Double folders after update to latest factory image - Google Pixel 5 Questions & Answers

Hello, since updating my rooted Pixel 5 to the November Image (via fastboot, flash-all.bat without -w switch) several folders in my internal storage are shown twice. The mentioned folders are in fact identical, if I create a file in one of them it also shows up in the other. After deleting a duplicated directory its twin is also gone but when I recreate it the twin gets resurrected as well.
Please see the following example (excerpt from ls -l in /data/media/0, called in an adb root shell):
Code:
drwx------ 2 u0_a250 u0_a250 3452 2020-11-08 14:31 Download
drwx------ 2 u0_a250 u0_a250 3452 2020-11-08 14:31 Download
After deleting the Download directory it looks like this:
Code:
d????????? ? ? ? ? ? Download
Any ideas how to solve this (without wiping)?
Thanks in advance.

Still nobody?

can anybody help me with this command line

this used to work when i did on my mytouch
cd /data/app-private/
ls
cp */sdcard
when i enter the command on my nexus i get error
cp: cant stat '*': no such file or directory
can some body please tell me how properly write the comand for a nexus one
What exactly are you trying to accomplish with the command? Are you trying to copy everything from /data/app-private/ onto your microSDHC card? If so, I would just (as root), do:
cp /data/app-private/* /sdcard
Make sure that you su to root before issuing the command, or you will get a permission denied error.
doesnt work either
What are you trying to do?
Can you link the place where you originally saw this command?

so from the command and the errors you get using your and nathanzachary's version it looks like
a) your missing a space between * and /
b) you need root access to read anything in /data
perhaps you can tell us what the output of the "ls" is and maybe exchange that with an "ls -al" ? that would show us the access rights. please just copy the whole session.

i know about the space typo. "ls" shows all of the protected apps on your device. this command line would basically let you save any protected app to the devices sdcard. in a nut shell paid apps for free but it wont work on my nexus. can anyone figure out what the command line should be for a nexus.
i am running cm 5.0.5.3 if it helps any
"ls" is the same as "dir" in windows. it just lists the content of the directory you changed into with "cd". thats why we need to see the complete output of your console session. that includes your input, the output and the error messages. this is the reason i wanted to see an "ls -al" to see the access rights of that directory. if you dont want us to see the aps than please cut out the names, but leave all dots
this is up till know a purley "linux" problem, we just need the right data.
EDIT: and do an "id" please, just after the ls -al, copy that output as well.

I just want to see which user you are on the shell and if the access rights match. Because if you are not root you don't even have list rights on that directory, which causes the "cant stat *" message
Did you root you N1? How do you access the shell? ADB? SSH? App? This is getting pointless

ok first of all how would it be possible to run cm 5.0.5.3 witch i posted my n1 is currently running if i didnt have root. i am using this coomand as i have been through better terminal emulator. if you would be so kind as to give me the exact command lines to get the output info you want i will gladly do so. besides what is the point of terminal emulator, adb, or fastboot without root.

Whichever method you use you'll have to use the su command to get root access first.
Connect your phone to your computer via USB cable, and make sure USB debugging is enabled on your phone (Settings > Applications > Development)
Enter adb shell to fire up Debug Bridge and enter shell mode
Enter su to become superuser
Enter cat /data/app-private/filename.apk > /sdcard/filename.apk to copy the file to the SD card.
exit
exit

i was talking about what command line to find the output info and if i should run that though terminal emulator or adb.the link is were i got the command line from. so r u telling me that the termial emulator method will not work on the nexus.
Yes you can use the terminal in the phone to back up your paid apps.
Which part of the steps (in the link) do you not understand?

Why so troublesome.
By using below two apps, you can simply copy out your purchase & install apps:
- Root Explorer
- Titanium Backup
Yeah, my guess was that he isn't logged in as root, thats why I need the output of "id".
I think it doesn't matter how you access the phone, trough a terminal emulator on the phone or though adb.
Just write us down the uid and gid value from "id", that should be little enough text to copy manually
for example, write down the red part:
bash-4.1# id
uid=0(root) gid=0(root)

[RECOVERY/BOOTSTRAP]Tweaked Safestrap v2.00a (ICS Leak) 06-13-2012

************************************
************************************
Note: Please uninstall Hashcode's Safestrap before you try installing this one. To accomplish this properly, you have to do two things:
1. Open up the Safestrap app from your launcher, and choose "Uninstall Recovery". Let it finish. It'll tell you whether or not it worked.
2. Then, go to Settings - Apps and find Safestrap. Click "Uninstall".
************************************
************************************
Installation of this app requires root privileges. If the installation does
not work, it is likely because you either:
a) don't have busybox installed.
b) you do have busybox installed but it doesn't have the functions we
need.
No problem. Just do this through adb or a terminal on the phone:
Code:
$ su
# mount -o remount,rw /system
# cp /system/xbin/busybox /system/xbin/busybox.old
# cp /data/data/com.hashcode.droid4safestrap/files/busybox /system/xbin/
# chmod 755 /system/xbin/busybox
# exit
Now it should work without a hitch.
************************************
************************************
Those of you who came from the Droid 3 might remember my customized version of Hashcode's Safestrap, which included a console, improved user-interface, non-safe flashing, etc.
I've finally got it to the point where I think it would be okay to release out in the wild. That being said, I'm not responsible for anything dumb you do to your own device.
I wouldn't bother using the non-safe flashing capabilities yet, seeing as how there hasn't really been any official releases using the new ICS kernels that have been leaked as of late. This feature is handy if you're a developer testing out update.zips for /systemorig, but for the average person you'd best pay heed to the warnings and just use Safestrap as it was originally intended; that is, leaving your /systemorig partition intact and only mess around with your "safe" /system. (Or /preinstall, actually, but that's not really important.)
The console is beyond useful. Editing build.prop settings on the fly without having to boot up and do it in a terminal emulator or via adb on the phone is much easier. If you know what you're doing, you can even extract single files from your old backups, modify your old backups, etc. That's just a small fraction, but those of you who would care about this functionality don't need me to say how important it can be.
I've included statically compiled versions of "bash" and "vim" so that there aren't any dependencies on the libraries usually found in /system/lib. Thus, you can use all of these utilities without having either /system or /systemorig mounted. You're free to add your own binaries in your home folder, which is located at /cache/.safestrap/home, or just pop them onto your sdcard.
Also, I have a battery monitor running so it will tell you what level your battery is at, and have put a lot of work into the visual appearance of the user-interface. There are so many things I've modified that it would be impossible for me to list them all here.
Anyways, try it out and let me know what you guys think. I hope you like it!
For those of you who are interested, I always post my sources on Github. You can find my code repositories here:

The .APK can be downloaded from my DropBox via the link below:

=========================
RECOVERY MENU REFERENCE
=========================
Select Highlighted Item - Enter or Power
Scroll Up - Volume Up or Left Arrow
**Note: The Left/Right Arrow keys may sound weird but since the menu is displayed in portrait mode, it just feels like you are pushing Up/Down.**
Scroll Down - Volume Down or Right Arrow
Direct Menu Selection - Hit the corresponding number/letter at the beginning of each menu item.
**ie: from the main menu, hit "6" to jump to the advanced menu.**
Go Back / Cancel - Caps Lock
===================
CONSOLE REFERENCE
===================
Keys:
--------------------
Tab - Tab
** Note: The Tab key is your best friend when using bash. It will auto-complete file/directory names for you, or list out the possible choices if you double-tap it after entering a few letters.
SYM - Alt
Shift - Shift
OK - Control
Caps Lock - ESC
OK+Shift - Toggle Caps Lock
OK+SYM - Toggle Alt Lock
** Note: The LED beside the Caps Lock button will illuminate when either Caps Lock or Alt Lock is enabled.
OK+Backspace - Force exit
OK+A - Home
OK+E - End
OK+C - Stop current process, ie: if a program you are running chokes up.
=========================
bash Commands:
--------------------
Here are a few of the more useful bash commands that you will use:
===========
ls, ls -a, ls -l, ll
===========
Code:
/ {}$ ls
- "ls" lists the files and directories within the current directory.
- You can also add a path after it to look for certain files or directories.
Code:
/ {}$ ls -a
- "ls -a" will list all files and directories, including hidden ones starting with a ".", ie: .bashrc in /cache/.safestrap/home. (The bash startup script).
Code:
/ {}$ ls -l
- "ls -l" will do a long listing, showing permissions, file sizes, etc.
Now, instead of using those parameters, I've made aliases within the .bashrc script so you will probably just want to type:
Code:
/ {}$ ll
- "ll" is an alias for "ls -a -l", so it will list all files/directories, hidden or not and list their properties.
Code:
/ {}$ ll
- By putting a path after "ll", it will single out the file. Add a "*" in there to act as a wildcard to list multiple files with the same first few characters.
- ie: "ll /system/lib/libc*" would display all the files and directories starting with "libc" within /system/lib as well as their properties.
========
cd
========
Code:
/ {}$ cd (path)
- Change directory. Pretty self-explanatory. Try doing:
Code:
/ {}$ cd ~/
- This takes you to the home folder. Pretty useless here but this is usually pretty handy in other scenarios.
Code:
/ {}$ cd ../
- Using "../" as your target will cause you to drop down a single directory in the tree.
**** Don't forget to hit tab to auto-complete directory/file names for you whenever you've already entered the first few characters. More accurate and much less typing. ****
=======
mv
=======
Code:
/ {}$ mv (source) (destination)
- "mv" is short for move. The source is the path to the file/directory you want to move, and I don't think i need to tell you what the destination is.
=======
rm
=======
Code:
/ {}$ rm (-r -f) (target)
- "rm" is used to delete the targetted files.
- "-r" means to recurse, or go into every inner directory automatically, erasing as it goes.
- You'll use the -r flag a lot, because you can't delete directories without it unless you use "rmdir", which is just more typing.
"-f" means force in case of permission errors, as long as you are root.
========
cp
========
Code:
/ {}$ cp (-f -a) (source) (destination)
- Copy the source file or directory to the destination.
- Use "-f" to force the copying, in the event of a potential overwrite.
- Use "-a" to maintain permissions of the original, you'll want to use this whenever you are copying anything important. I just use it all the time, but sometimes it won't work, such as when copying from an /sdcard to either the /system or /data partition.
-This is because the file system of your /sdcard doesn't care about permissions.
=========================
============
[VIM REFERENCE]|
============
Vim deserves, and has, entire websites devoted to it's use. Here are some of the basics.
------------
Using Vim|
------------
From the console, simply type:
Code:
/ {}$ vim
Where is obviously replaced by the name of the file you are editing.
Multiple files can be opened at once by just adding them as parameters to vim:
Code:
/ {}$ vim file1 file2 file3 file4 filen
---------------
Insert Mode |
---------------
This is the mode you want to be in to make any visible changes to the file you are editing.
- Enter Insert Mode by pushing "i" when vim opens.
- Exit Insert Mode by pushing Capslock.
Keys:
------
Backspace - In insert mode, deletes the previous character.
Capslock - Exits insert mode
---------------
Visual mode |
---------------
By typing in "v" instead of "i", you will enter visual mode; this is Vim's fancy way of saying you will be selecting text.
Keys:
------
- Copy or Cut text by hitting "y" or "d" after you've made a selection
- Paste with "p" or "P" (that is, Shift+p). Shift-"p" puts the text before the cursor whereas plain lowercase "p" will paste it after.
- When you're done highlighting what you want to either cut or copy, just hit Capslock to go back to Command Mode.
-------------------
Command Mode |
-------------------
Vim starts out in Command mode. It seems confusing but once you get used to it, you can't help but hate Notepad.
Some of the more common commands are listed below.
Keys:
------
u - Undo
Shift+r (Usually denoted as R) - Enter Replace Mode, where you are replacing text instead of inserting it.
[#]yy - Yank (copy) the current line if you just entered "yy", or copy "#" lines if you enter #yy, ie: 5yy to copy 5 lines.
[#]dd - Delete (cut) the current line, or delete # lines if preceded by a #.
p - Pastes after the cursor
Shift+p (usually denoted as P) - Pastes before the cursor
:[#] - (Ignore the square brackets; a colon followed by a number goes to that particular line in the text file you are editing. eg: ":5" goes to line 5. (Obviously, don't type the quotation marks in.)
Note: - If you are in Insert mode, you will have to push Capslock to exit and be allowed to enter Command Mode by entering a ":"
- It's fairly common practice to just hit Capslock twice whenever you're done inserting so that you are sure to be able to hit ":" and proceed to enter another command.
:w - Write (save) the currently open file.
:q - Quit. If you haven't saved since making any changes, it will prompt you to either save your changes or append a "!" after "q" to quit without saving. (See below)
:q! - Force quit without saving.
:wq - Save and then quit.
:e [path to filename] Opens up another file; you can use bash command-line completion to scan the current directory, or otherwise just enter another path.
:next or rev - Aptly named, move to the next or previous file if you opened vim with two or more files as parameters, ie:
Code:
/ {}$ vim file1 file2
:/[text] - Search for "text". ie: ":/search" will find instances of the text "search" in the current file and highlight them.
Note: You need to make sure you are aware of regular expressions/escape characters before using this reliably; it's not broken if you can't seem to search for a quotation mark or other special characters, you need to precede them by a \. ie: to look for a double-quote symbol " you would enter :/\". The \ tells it that the next character is meant to be taken literally and not symbolically.
:/[text]/[moretext]/gc - Replace "text" with "moretext" everywhere in the file and ask confirmation for each change. If you forget to type in the "gc" at the end, it'll just replace everywhere without asking you for confirmation.
That's all I'm going to put here. There are tons of guide out there and I've already preloaded a pretty awesome configuration (.vimrc located at /cache/.safestrap/home) and runtime files. If you want to quickly access the configuration file, you can type ",,e" in Command Mode and it will automatically pop open.
================
COLOR CHANGING
================
1. If you want to change the color scheme, you need to figure out what the RGB code for the color you want is. Here's a website that provides a large table of colors and their corresponding RGB color code:
http://web.njit.edu/~kevin/rgb.txt.html
For example, let's say we like the "SlateGray4" color from the table linked above want to use it for the menus in both Safe and Non-Safe mode. As you can see, in the "R;G;B; Dec" column, the three codes we are interested in are 108, 123 and 139.
2. Now that you know the color codes, in our case 108, 123 and 139, we simply do the following:
a) Push 7 from the main menu, or scroll down and select "console menu".
b) Push 1, or scroll down and select "open console"
(Don't panic if it takes a few seconds to load the console; on the first initialization or after wiping the /cache partition, it will take a few seconds to reconfigure itself.)
c) At the prompt, enter the following:
Code:
/ {}$ ns_rgb 108 123 139
/ {}$ s_rgb 108 129 139
/ {}$ cc
/ {}$ exit
Now, it'll take another second or two and when the menu pops back up, you'll see that it is the color we chose from the table. The "ns_rgb" command takes three parameters, each of which correspond to the R, G and B values of the color code, and uses them for the "Non-Safe" (hence the "ns") menu color.
Similarly, the "s_rgb" command, (well technically, it's a bash function but anyways...) takes the same three parameters. It is applied to the "Safe" menu color.
The "cc" command actually sets the color, so don't forget to enter it. Otherwise, you won't notice a change when you exit out from the console.
Feel free to experiment with different colors! If you don't what you've done and just want to reset it back to the way it way, just wipe the cache partition:
a) Push 3, or scroll down to "wipe menu".
b) Push 1, or just hit Enter on "wipe cache".
c) Confirm your selection by pushing 8 or scrolling down and selecting "yes - wipe cache".
=================================================
More to come as I have more time.
Awesome, just a couple questions:
1) where is the dropbox download
2) if I already have the hashcode safestrap installed, how does one install yours? And what happens if I am already running a custom ROM?
Sent from my XT894 running ICS
Good call, I should make that clear.
Make sure you uninstall Hashcode's Safestrap, both inside the app and from the Android Settings menu before you install this .APK.
- download the pimped apk, uninstalled safestrap recovery, uninstalled old safestrap
- installed pimped safestrap, install new safestrap recovery, reboot
looks fine
anyone who restorerd a full backup of ics leak with safestrap 2.0?
friend got a problem, and system was unbootable and lost root....
Yeah, I've done it about four times today. No problems using either my modified version or Hashcode's original Safestrap v2.00.
It was no problem recovering from a busted /system partition either; just fastbooted the /system and /preinstall partitions only from the .219 leak, then rebooted the phone into the stock recovery and re-applied the .208 leaked update .zip file. Re-rooted with the technique I posted the other day without a hitch.
Didn't even lose any data...

I'm not following you here, this happened to you using my version?
I've done it countless times while testing this before I released it and have been working with this code for a long time; it's pretty foolproof.

Having some issues with getting safestrap installed in the 208 ICS leak. The app installs fine, click install and it says install complete, but I have no safestrap. Even after a reboot it still says "Not Installed" in the safestrap app. Anyone else experiencing this issue?

So I have tried to restore 2 different backups using your safestrap and I keep on getting MD5 mismatch errors. I have tried deleting and regenerating the checksum file via ADB, disabled signature check, changed the folder name, pretty much everything I could think of. So whats going on?
An MD5 error would indicate that your backup files don't match the checksum that was generated at the time the backups were initially generated, which most likely means that your backup files may have become corrupted... unfortunately, this can happen with any files stored on an SD card.
Don't worry too much though, there still a really good chance that you can manually restore your data, although if your MD5's aren't matching there's a tiny possibility that your backup files are toast.
*** I'll assume you are trying to restore a "safe" system backup. If it's a "non-safe" backup, then just interchange "/systemorig" and "non-safe" for "/system" and "safe", respectively. ***
You have to manually wipe your /data and /cache partitions in the wipe menu, then format "/system" in the mounts menu. This way you have a clean slate to extract your backups to.
Try this from within the console in the recovery. (Depending on whether you backed up to the internal (/emmc) or external (/sdcard) card, just mount the required partition as follows:

Code:
{}$: mount /emmc
External card:
Code:
{}$: mount /sdcard
(To be sure, it won't hurt if you just mount both of them.)
I'll assume you used the external sdcard which is mounted at /sdcard. Now:
Code:
{}$: cd /sdcard/safestrap/backup
If you list this directory (using "ll", or "ls -l"), you'll see a list of backup directories, prefixed by either "safe" or "nonsafe" and followed by the date and time of the backup. Remember, you can use the Tab key to autocomplete file/directory names so you don't have to type in the entire path. Here's an example:
Code:
/sdcard/safestrap/backup {}$ ll
total 192
d---rwxr-x 6 1000 1015 32768 Jun 24 04:42 ./
d---rwxr-x 3 1000 1015 32768 Jun 6 04:41 ../
d---rwxr-x 5 1000 1015 32768 Jun 6 04:41 nonsafe-2012-05-25.19.22.55/
d---rwxr-x 2 1000 1015 32768 Jun 8 20:42 nonsafe-2012-06-08.13.35.00/
d---rwxr-x 2 1000 1015 32768 Jun 20 03:13 safe-2012-06-19.20.10.44/
d---rwxr-x 3 1000 1015 32768 Jun 24 13:17 safe-2012-06-23.16.25.49/
/sdcard/safestrap/backup {}$
Let's use "safe-2012-06-19.20.10.44" for my example, substitute your own directory name as I'm sure it'll be different.
Go ahead and list the contents by entering the next two commands:
Code:
/sdcard/safestrap/backup {}$: cd safe-2012-06-19.20.10.44
/sdcard/safestrap/backup/safe-2012-06-19.20.10.44 {}$: ll
You should see something like:
Code:
/sdcard/safestrap/backup {}$: cd safe-2012-06-19.20.10.44
/sdcard/safestrap/backup/safe-2012-06-19.20.10.44 {}$ ll
total 1117760
d---rwxr-x 2 1000 1015 32768 Jun 20 03:13 ./
d---rwxr-x 6 1000 1015 32768 Jun 24 04:42 ../
----rwxr-x 1 1000 1015 74135552 Jun 20 03:13 cache.ext3.tar*

/sdcard/safestrap/backup/safe-2012-06-19.20.10.44 {}$
Now that you're at the proper path for the backup you want to restore, we can manually extract the files from the backups. (If you haven't already done so, remember to wipe /data, /cache and /system.)
We have to mount /system, /data and /cache:
Code:
/sdcard/safestrap/backup/safe-2012-06-19.20.10.44 {}$ mount /system
/sdcard/safestrap/backup/safe-2012-06-19.20.10.44 {}$ mount /data
/sdcard/safestrap/backup/safe-2012-06-19.20.10.44 {}$ mount /cache
*** Don't worry if you get a message saying the device can't mount because it is busy, that just means it's already mounted. ***
Code:
/sdcard/safestrap/backup/safe-2012-06-19.20.10.44 {}$ tar xvf system.ext3.tar -C /
Wait a minute or two for it to finish, then:
Code:
/sdcard/safestrap/backup/safe-2012-06-19.20.10.44 {}$ tar xvf data.ext3.tar -C /
Wait some more... then:
Code:
/sdcard/safestrap/backup/safe-2012-06-19.20.10.44 {}$ tar xvf cache.ext3.tar -C /
Done. If you want, you can restore your /systemorig partition now but you probably don't want to do that, not if your MD5's don't match up.
Assuming you just restored a "safe" system backup and you are in "safe" mode, you can cross your fingers and reboot. If you aren't in safe mode, switch over to it from the safe-boot menu before you reboot.
At this point, you should have restored that backup manually. Hope that helps, it's always a bummer to lose your data.
You sir need a medal. That was the best response I could have expected. I will try this later at work. I regenerated the checksum file but like you said, it has to be at the time of the backup.
Hey man, no prob. I figure I might as well do it step by step so that others can reference this in the event of a similar situation. Hope it works out for you.
To be honest, I got frustrated and gave up. I have discovered that on the 7-4 AOKP build, if I lose data all I have to do is wipe cache and dalvik cache and boom, I have have 4G. Now if only I can get a init.d tweak to clear both on startup then all I would have to do is reboot the phone to restore data. So long story short, I'm sticking with the non ICS-Leak AOKP, no need to risk going off the upgrade path and alot less of a hassle.

Dual Boot Atrix: Simplified and Standalone (30 Jan 2013)

Quickly and conveniently leverage the strengths of mainstream ROMs and kernels using my new simplified and standalone dual boot tools!
Here I assume that your rooted Atrix with unlocked boot loader already hosts a ROM on EMMC. Even if you're not dual booting, I think you will find some or all of these tools helpful!
Steps
Code:
1. Boot to Recovery
2. Flash SmartPart FZ (partition SD card right on your phone!)
3. Flash Copy-ROM (copy ROM --- all except boot image --- from EMMC to SD card)
4. Flash Atrix Boot Emporium V3.0 (boot ROM on SD card to verify success)
5. Flash another ROM of your choice to EMMC and reboot (optional)
Links
SmartPart-V1.0-signed.zip: http://www.mediafire.com/?wm96y92g3lla3ot
Copy-ROM-V1.0-signed.zip: http://www.mediafire.com/?i068xs1ktdkd183
Atrix-Boot-Emporium-V3.0-signed.zip: http://www.mediafire.com/?zsf4is8fbzs7sf9
All zips tested working on my AT&T Atrix + Samsung 32GB Class 10 SD using ClockworkMod Recovery 5.0.2.0.
If everything goes well, you will have demonstrated "standalone" dual boot capability on your Atrix beauty without a computer! In fact, "unlisted" ROMs may be supported. For example I downloaded upndwn4par's CSROM V7.0 (26 Jan 2013), ported it to SD and then successfully booted it with faux's 1.0 GHz GB boot image featured in Emporium.
Walk-Through
Step 1: I prefer ClockworkMod Recovery 5.0.2.0 as it appears to be the most compatible recovery for Atrix.
Step 2: SmartPart FZ shrinks your (external) SD card's FAT32 partition by 4GB and adds three new “ext” partitions: /system, /cache and /data of ample size to host virtually any Android ROM. SmartPart FZ takes about 30-45 seconds to partition a Class 10 card.
Important! You MUST flash SmartPart FZ from internal memory (“choose zip from internal sdcard”) because if you flash it from external memory, your SD card gets mounted and you can't partition a mounted filesystem. Also it is a good idea to flash SmartPart FZ immediately after booting to CWM; else your SD card could get mounted accidentally.
Not sure you want dual boot? Just select the “Restore” option and Smart Part FZ restores your SD to its original state by removing any existing ext partitions (up to three consecutive partitions) and growing your FAT32 partition back to its original size. This takes about 10-15 seconds on a Class 10.
Note: SmartPart FZ is fundamentally the same as its shell script predecessor ( http://forum.xda-developers.com/showthread.php?t=1651356 ) --- except that FZ runs unattended and does not backup anything.
Step 3: Copy-ROM, with the “EMMC to SD Card” option selected, copies all files on /system, /cache and /data files to the equivalent SD card ext partitions created in Step 2. Your EMMC ROM becomes a “live backup” on SD that you can boot to, thus freeing up EMMC to host another ROM of your choice.
One advantage of copying a ROM to SD is that you can first configure it the way you wish (GApps etc.), and then copy it over instead of having to flash individual customized zip files to SD. Then you're ready to flash a different ROM to EMMC, or blast off with a fully redundant system.
Copy-ROM uses the “cp -a” command, which I have found to be several times faster than cloning partitions. How much faster depends partly on disk usage since cloning copies everything, including empty space. Example: Port CM10 Liquid Smooth with ~100 total apps to a Class 10 SD. Clone ROM takes 15 minutes. Copy-ROM takes less than 2 minutes.
Another advantage of copying files over cloning partitions is that you don't have to worry about partition size mismatch. And I would not want to modify EMMC partitions --- too scary for me.
Step 4: Use Emporium V3.0 to boot a supported ROM whether it is hosted on EMMC or SD. Emporium contains boot images and corresponding /system/lib/modules for:
Code:
ICS MROM
ICSROM
CM10 epinter (Stock and OC1300)
CM10 Th3Bill (AOKP, Liquid Smooth and MIUI)
CM7 MROM (HV and SV)
CM7 Neutrino (EE, GT and GT+)
GB MROM (HV and SV)
GB NottachTrix (ATT and faux 1.00, 1.30 and 1.45)
Emporium V3.0 is less than 120 MB compressed and 10-15% more uncompressed. Each file named “boot.img” was lifted from its respective ROM zip. Each file named “boot-sd.img” exactly matches its big brother boot.img, except that ramdisk was modified to redirect ROM filesystem mounts from EMMC to SD:
Code:
/system: mmcblk0p12 to mmcblk1p2
/cache: mmcblk0p15 to mmcblk1p3
/data: mmcblk0p16 to mmcblk1p4
except for CM10 boot images. Please read CM10 Notes below.
Emporium Options
One of the dilemmas associated with dual booting is how to clear /cache and or /data. Of course CWM can do this, but only for ROMs hosted on EMMC: It does not recognize ROMs hosted on SD. And CWM is a little cumbersome to use since the clearing options are not all on one page. Emporium addresses these issues by displaying a single page with options to:
Code:
Clear /cache and /data/dalvik-cache
Clear /data (BE CAREFUL)
on EMMC or SD depending on the option selected on the first page. Now you can conveniently boot to a jet clean ROM whether it is hosted on EMMC or SD. Of course if you just copied a healthy ROM to SD, it is probably not necessary to clear.
I will explain the third option: Extract Boot Files to /sdcard/Boot later.
All three options are null by default.
Step 5: Nothing new here if you've ever flashed a ROM.
Now if for some reason you want to reverse the process and copy a ROM from SD Card to EMMC, just flash Copy-ROM and this time select the “SD to EMMC” option. Then flash Emporium or fastboot your EMMC ROM with the boot image of your choice. You may want to Nandroid-backup or Titanium Backup before doing a reverse copy.
Of course there are faster ways to switch between ROMs. But the tools presented here give your Atrix a simplified, standalone dual boot capability using all flashable zips.
Once you're comfortable using these flashable zip tools, you can then move onto “live” boot switching using all soft keys. To that end, I rolled up all of Emporium's boot images and my simplified boot switcher “boot-rom.sh” to a single directory named “Boot” which also includes the user-configurable subdirectories ROM1 and ROM2. Just select Emporium's option: Extract Boot Files. This extracts Emporium's Boot directory and its contents to the top directory of your SD card. After that you can copy your ROM boot images to Boot/ROM1 and Boot/ROM2 using Root Explorer or other suitable app. Copy boot.img to {path-to-SD}/Boot/ROM1 and boot-sd.img to {path-to-SD}/Boot/ROM2.
Now you can switch “live” between ROMs or boot to recovery using the appropriate command string:
Code:
sh boot-rom.sh (reboot to current ROM)
sh boot-rom.sh 1 (boot to ROM1)
sh boot-rom.sh 2 (boot to ROM2)
sh boot-rom.sh 3 (boot to Recovery)
Here is Emporium's boot-rom.sh:
Code:
#!/system/bin/sh
echo Motorola Atrix Dual Boot ROM1 emmc or ROM2 SD card
echo sendust7 @ xda developers
echo
echo Usage: sh boot-rom.sh N
echo where N = blank \(reboot to current ROM\)
echo 1 \(reboot to ROM1\)
echo 2 \(reboot to ROM2\)
echo 3 \(reboot to recovery\)
echo
echo "Home directory: $HOME"
echo
if [ $# -eq 0 ]; then
echo Rebooting to current ROM. Please wait...
sleep 3
reboot
elif [ $1 -eq 1 ]; then
if [ -f $HOME/ROM1/boot.img ]; then
cat $HOME/ROM1/boot.img > /dev/block/mmcblk0p11
echo Rebooting to ROM1. Please wait...
sleep 3
reboot
else
echo "boot.img not found. Check home directory."
exit 1
fi
elif [ $1 -eq 2 ]; then
if [ -f $HOME/ROM2/boot-sd.img ]; then
cat $HOME/ROM2/boot-sd.img > /dev/block/mmcblk0p11
echo Rebooting to ROM2. Please wait...
sleep 3
reboot
else
echo "boot-sd.img not found. Check home directory."
exit 1
fi
elif [ $1 -eq 3 ]; then
echo Rebooting to recovery. Please wait...
sleep 3
reboot recovery
else
echo "Invalid option. See Usage."
exit 1
fi
return 0
Note that boot-rom.sh is more robust than previous versions. The improved logic displays the $HOME directory and also displays an error message if it can't find ROM1/boot.img or ROM2/boot-sd.img under $HOME. If you are using Script Manager to launch boot-rom.sh, go to Settings>More>Advanced>Configuration, set Home directory to {path-to-Boot} (for example, “/storage/sdcard1/Boot” for CM10), press field at bottom to select Home directory, then select “Export $HOME” and “Browse as root”. So when you launch boot-rom.sh from Script Manager, the $HOME directory should be: {path-to-SD-card}/Boot. If not, you get an error message if you enter an argument of 1 or 2 in the command string.
Be sure to launch boot-rom.sh as root.
CM10 Notes
If you unpack any of Emporium's CM10 files named “boot-sd.img”, note that I made two small changes in ramdisk in addition to rerouting filesystem mounts:
The “init” executable was replaced with the MROM ICS init
init.olympus.rc was modified to grant elevated privileges in mkdir /storage/sdcard{0,1} per the MROM ICS init.olympus.rc
I found these two additional steps necessary to successfully boot CM10 from SD and to make apps run properly. That said, these “boot-sd.img” files should be viewed as experimental, as your mileage may differ. But no kernels were modified.
I think that porting CM10 to SD has some merit as the /system partition is easily up-sized to hold apps moved from the /data partition. Why would I make this obscure statement? Well it turns out that CM10 apps running under /system appear to have more privileges than those running under /data. I demonstrated this behavior on at least two different CM10 builds hosted on both EMMC and SD using “aLogcat” a GUI-based system logcat generator. When I launched aLogcat under /data/app, it would not display logcat to screen nor save results to a file. Then I moved it to /system/app and the problems disappeared.
Enjoy.
Troubleshooting
No wifi? Try re-flashing with Emporium since it refreshes /system/lib/modules.
Soft-brick? You may have attempted to boot a non-existent, corrupt or incompatible ROM.
Unusually fast completion of zip flash? An error has probably occurred, and you may need adb and recovery log to debug.

It generates a "live" backup of your existing ROM on your SD card --- a ROM you can boot to. Then you can flash another ROM to internal memory just as you normally would.
If all goes well, you will have successfully dual booted your Atrix.

Hi sendust. Thank you very much! :good:
Managed to succesfully run TheBill's PA 299 from my sdcard (using AOKP boot.img) and restore and run a backup of a GB rom (nottachtrix based) to/from emmc.
I also managed to reboot from GB to PA299 using Script Manager by following the above quoted steps.
I can't seem to get Script Manager to run the same script from PA299 using 1 as argument to reboot into my GB rom. I did set Home directory as instructed to /storage/sdcard1/Boot but the log still says Home = / and it returns boot.img not found.
Any help would be appreciated

I experienced similar behaviour with Script Manager (SM) running under /system/app. Then I moved it to /data/app and the problem went away.
If SM resides in /data/app and still doesn't work, uninstall it and download the latest version from Play Store.

I realise the problem is with SM and not with the script cause it runs fine in GB
Are there any other options?

I would check permissions for SM. Below is what I have for CM10 Liquid Smooth (scroll down to "os.tools.scriptmanager-1.apk"). Note that the permissions match those of the other apps.
Another option would be to configure a different app like Terminal Emulator to execute boot-rom.sh as root from the Boot directory.

After few hours of trial and error finally managed to get it working!
Sendust you're a star!
SM just didn't want to configure (probably) because it was installed while running rom from sd. Once I got it installed running the rom on emmc and copied emmc to sd it kept the configuration. I just had to change the argument.
Thanks and keep up the good work :good:

I duplicated the problem on my Atrix. In fact I couldn't even get ICSROM 1.4.6 to boot from EMMC. I tried reformatting /system, /cache and /data and re-flashing. Got a fixed Big-M with fadeout, followed by a single-blink and then blank for many minutes.
Then I CWM flashed MROM boot.img using Emporium 3.0 but it hung up at the pulsating Big-M. In retrospect, I may not have waited long enough.
Then I flashed MROM ICS right over ICSROM and it booted.
Then I reflashed ICSROM 1.4.6 and rebooted. Same behavior as at the start.
Then I CWM factory reset and flashed ICSROM 1.4.3 (previous version). This time, I got pulsating Big-M for several minutes (expected due to factory reset) followed by Location Consent screen, indicating a successful boot. So ICSROM 1.4.3 appears to work.
Then I flashed Emporium's ICSROM 1.4.6 boot.img (EMMC) and rebooted. Big-M came up and then... blank --- as before.
So I reinstalled 1.4.6 ROM, factory reset, fastbooted the 1.4.3 boot image (pulled from ICSROM 1.4.3 zip file) and voila... 1.4.6 came up.
These results intimate an issue with the ICSROM 1.4.6 kernel.
Unfortunately there is not a straightforward means of obtaining kernel debug messages (dmesg >> dmesg.txt) on a failed boot: http://bootloader.wikidot.com/linux:android:kmsg
Now if you Copy-ROM ICSROM 1.4.6 to SD, you need a modified boot image. Try this one:
Link (boot-icsrom-1.4.3-sd.img): http://www.mediafire.com/?57b25z5hkid2bc2
Modified init.olympus.rc code (ramdisk):
Code:
mount ext3 /dev/block/mmcblk1p2 /system noatime nodiratime wait ro barrier=1
mount ext3 /dev/block/mmcblk1p4 /data nosuid nodev noatime nodiratime wait barrier=1
mount ext3 /dev/block/mmcblk1p3 /cache nosuid nodev noatime nodiratime wait barrier=1
[UPDATE, 05 Feb 2012 1630 PST]
OK. I may have found a problem with the stock ICSROM 1.4.6 boot.img. If you unpack it and navigate to /ramdisk/default.prop, you will notice several "read-only" settings --- ones that can only be modified in ramdisk. I made one small change: Set ro.debuggable=1 (instead of 0). Here is the modified default.prop:
Code:
#
# ADDITIONAL_DEFAULT_PROPERTIES
#
ro.secure=0
ro.allow.mock.location=0
ro.debuggable=1
persist.sys.usb.config=mtp
After making this one simple change, I repacked the 1.4.6 boot.img (boot-repack.img) then did the following:
Code:
Reboot to CWM
Perform factory-reset
Flash ICSROM 1.4.6
Reboot to fastboot
fastboot flash boot boot-repack.img
fastboot reboot
This time, I still got the familiar Big-M fadeout followed by the single-blink Big-M. But then 30 seconds later, the pulsating Big-M appeared, and several minutes after that, ICSROM 1.4.6 finally came up.
Link (boot-icsrom-146-emmc.img): http://www.mediafire.com/?5da1ngcny8px14w
Note: In the ICS MROM boot.img, "ro.debuggable" is already set to 1.
The short answer is that the ICS kernels are presently not stable, which is why I hesitated to include them in Atrix Boot Emporium.
Hope this helps.
what happens if i use the smart formater to my ext.sdcard and on the card are swap partitions and webtop partition? do i lose them??

I deliberated much about this and decided that for V1.0 I would stick with three (primary) ext partitions.
So yes, if you flash SmartPart FZ V1.0 and select the "Create" option, it will first do this:
Code:
echo "We first remove any existing partitions beyond the FAT32 partition..."
#echo "ENTER to continue; CNTL-Z to exit." ; read
parted /dev/block/mmcblk1 rm 4 > /dev/null 2>&1
parted /dev/block/mmcblk1 rm 3 > /dev/null 2>&1
parted /dev/block/mmcblk1 rm 2 > /dev/null 2>&1
parted /dev/block/mmcblk1 print
and then it wll create three new partitions, one each for /system, /cache and /data:
Code:
parted /dev/block/mmcblk1 mkpartfs primary ext2" $val3" "$val4"
parted /dev/block/mmcblk1 mkpartfs primary ext2" $val5" "$val6"
parted /dev/block/mmcblk1 mkpartfs primary ext2" $val7" "$val8"
where the $val parameter values are partition boundaries based on the FAT32 right-hand boundary and fixed partition sizes defined in the shell script.

oh thats sad. i wanted to try this because i love to test roms but i dont want to give up on my webtop partition.
Using your 1.4.3 boot.img and it still doesnt want to boot in the rom Dont know why, but after i flash the emmc with another rom it doesnt boot, before that it booted from sd

OK that's good info. The file: boot-icsrom-1.4.3-sd.img was intended to boot 1.4.6 on SD. But of course it does not have the "ro.debuggable=1" fix. So when I got 1.4.6 to boot on EMMC using the fix:
Link (boot-icsrom-146-emmc.img): http://www.mediafire.com/?5da1ngcny8px14w
I realized that boot-icsrom-1.4.3-sd.img probably would not boot 1.4.6 on SD. And such was the case for me.
Did you try this:
Code:
Reboot to CWM
Perform factory-reset
Flash ICSROM 1.4.6
Reboot to fastboot
fastboot flash boot boot-icsrom-146-emmc.img
fastboot reboot
I would not be surprised if you got different results based on what the ICSROM author says...

But please don't your hopes too high guys. Remember this ROM runs different on every device.

[UPDATE 07 Feb 2013, 0745 PST]
So I unpacked the ICSROM 1.4.6 and MROM boot images and found that the ICSROM init.olympus.rc (the device-specific script launched at boot time by the init process) is three times the size of MROM's init.olympus.rc.]. More to follow...

[TUTORIAL]How to unbrick your N4

How to unbrick your N4 ​I'm not responsible for anything that happens with your device!
I accidently flashed a S4 ROM.
After I noticed that, I tried to flash a factory image, but it booted for a very long time and WiFi, signal and other radio stuff didn't work.
Then I searched for help here, but anything they suggested didn't work, so you might be thinking that the only solution would be to send the device for repair.
But I searched for a solution anyway and found it
So this is what you need to download:
Nexus 4 Unbrick.zip
For Nexus 4 16GB you also need to download this files:
Nexus 4 Unbrick 16 GB Files.zip
OK let's start:
First thing we need to do is extracting everything and installing the LGNPST (this is for Windows 8, but I don't see why it shouldn't work on other versions).
Open your extracted Nexus 4 files folder
Open the LGNPST folder
Install "LGUnitedMobileDriver_S4981MAN38AP22_ML_WHQL_Ver_3.8.1.exe", it's located under "LG_USB_Driver"
Install "LGNPSTv1.3_Lab_Verison_RightClickReg.exe", located in root of the folder
Install "LGNPST_GenericModels_Ver_5_0_12_0", located under "NPST Generic Components and Models"
Install "LGNPST_Components_Ver_5_0_20_0", also located under "NPST Generic Components and Models"
Copy the Models folder to C:\LG Electronics\LGNPST\
Start a command prompt as admin
Type: regsvr32 "C:\LG Electronics\LGNPST\Models\LGNPST_LS970.dll" (yes, I know this is a .dll for the Optimus G)
That's it
If you got no ADB or fastboot drivers installed, install the Universal ADB Driver.
Now start the LGNPST and get your N4 into download mode:
Turn the phone off.
Make sure the phone is off.
Plug a USB cable into your PC, AND ONLY INTO YOUR PC. THE PHONE PART COMES NEXT.
Hold down the volume up and down buttons for 2 (two) seconds on your Nexus, and continue to hold the volume up and down buttons while pluging in the USB cable which is connected to your PC. Continue to hold the buttons until the download mode screen appears. Now step five.
Once the download mode screen comes up, let go of the volume buttons.
Thanks to @Connor Baker for sharing this method
Now you should get a screen like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Now your LGNPST should look like this:
In the bottom center you see DLL and BIN File.
Click on the folder symbol and select LGNPST_LS970.dll (and again, yes, I know it's for Optimus G, trust me I know what I'm doing)
Then select the .bin file you extracted before.
Now click start and it'll flash it.
Your N4 will reboot automatically, but the LGNPST reached only 85%, thats's normal (but please wait until the 67% changed to 85% before you close it)
The LGNPST will say you, that you should reboot again to download mode to finish the process, but the only thing it does is giving you an error message.
So now you have a developer firmware on your device and it's encrypted so you can do nothing.
Reboot into bootloader with Vol - and power button.
Now start flash_all.bat in the flashfactory folder and the program will do the things by itself.
Now you are completely on stock and should have a fully working device
Next steps for Nexus 4 16GB:
First thing I need to say: No, this doesn't work!
First step is rooting your phone (search through XDA if you don't know how; thanks to Rockstar600 for remembering me)
Copy the files you downloaded for the 16GB Version on your Nexus 4 (without the CWM Image).
If "dd" got renamed to "dd.bin" rename it back to "dd".
Install Root Browser or an similar app and copy the files to your /system directory.
Then flash the CWM Recory Image.
To do that open the folder that contains the Factory Image flashable with fastboot and do CTRL+Right Click in that folder and select "Open Command Prompt here" or something like that (don't know the exact name).
Get your device into fastboot mode with Vol- and Power.
Now type:
Code:
fastboot flash recovery recovery-clockwork-touch-6.0.4.7-mako.img
Then reboot into recovery.
I think you leaved CMD open.
So now type:
Code:
adb shell
mount /system
cp /system/dd /
chmod 755 /dd
/dd if=/dev/block/mmcblk0 of=/system/pgpt8G.img bs=512 count=34
/dd if=/dev/block/mmcblk0 of=/system/sgpt8G.img bs=512 skip=30777311
umount /data
umount /cache
umount /system
df -h
Now the output should look like this:
Code:
# df -h
Filesystem Size Used Available Use% Mounted on
tmpfs 911.7M 48.0K 911.6M 0% /dev
There shouldn't be a extra line.
If there is no extra line then continue with:
Code:
mount /system
/dd if=/dev/block/mmcblk0 of=/system/DDR bs=512 skip=15267840 count=2015
/dd if=/system/DDR of=/dev/block/mmcblk0 bs=512 seek=30775296 conv=notrunc
/dd if=/system/sgpt16G.img of=/dev/block/mmcblk0 bs=512 seek=30777311 conv=notrunc
/dd if=/system/pgpt16G.img of=/dev/block/mmcblk0 bs=512 seek=0 conv=notrunc
parted /dev/block/mmcblk0
Then type p and press enter and the output should look like this:
Code:
# parted /dev/block/mmcblk0

25 15.8GB 15.8GB 507kB grow
Notice that userdata partition is 14.1GB in size
In case parted reports an error I suggest to return back to the old 8G partition tables, see below.
You can close parted with simply typing quit.
Now reboot the phone into bootloader: type reboot and hold 'Up' button to enter bootloader menu.
Then type:
Code:
fastboot erase userdata
fastboot -w
Now again start the flash-all.bat in your folder.
Now you have your 16GB back
Return back to the old 8G partition tables:
In case parted reported an error, put the old 8G partition tables back. This should not happen but never say never:
Code:
/dd if=/system/sgpt8G.img of=/dev/block/mmcblk0 bs=512 seek=30777311 conv=notrunc
/dd if=/system/pgpt8G.img of=/dev/block/mmcblk0 bs=512 seek=0 conv=notrunc
Fix for Bluetooth and MAC adress:
For bluetooth:
- In /persist directory create bluetooth directory. Under the new directory create a file named .bdaddr (don't miss the dot!)
Edit the file and put 6 random characters in it. Even better, if you can do this in a hex editor and put 6 random bytes, not just printable characters.
- Set execute and read permissions for everybody on /persist/bluetooth directory and change owner of .bdaddr to bluetooth:bluetooth and permission to 660 (read/write for owner and group and nothing else). In command line:
Code:
chown root:root /persist/bluetooth
chmod 755 /persist/bluetooth
chown bluetooth:bluetooth /persist/bluetooth/.bdaddr
chmod 660 /persist/bluetooth/.bdaddr
For mac address:
- In /persist directory create wifi directory. In the new directory create a file named .macaddr (don't miss the dot!)
Edit the file and put 12 random hex numbers in it (0-9, A-F), save.
- Set execute and read permissions for everybody on /persist/wifi directory and change owner of .macaddr to wifi:wifi and permission to 660 (read/write for owner and group and nothing else). In command line:
Code:
chown root:root /persist/wifi
chmod 755 /persist/wifi
chown wifi:wifi /persist/wifi/.macaddr
chmod 660 /persist/wifi/.macaddr
- run /system/bin/conn_init program. Can be run in root explorer(choose Linux Script Handler when you open it), or in adb shell:
Code:
su
/system/bin/conn_init
Then reboot and check if the changes got applied in settings

[GUIDE] Making Dump Files Out of Android Device Partitions

Use:
The main purpose is to make a file that contains all data in android specific partition. This is really handy in case of dumping leak firmwares.
Pr-requirement:
- Rooted device.
- Knowledge of how to use adb or Terminal Emulator.
The first step of making dump files out of device partitions is to locate its mounting points..!!
So in our tutorial, we will make it in 2 sections. Section 1 for how to get mounting points, and section 2 for how to get partition dumped..
Keep in mind that this is xda-university; so my target is to show beginners how to do that manually, without the aid of any tool, so they can get the concept behind it.. OK let's begin..!!
Section 1:
Getting mounting points​There are several methods to achieve this, but we will discuss the easiest methods that give efficient information about the partition that you want to know its mounting point.
All these methods will be described using adb shell.
Way #1
Code:
adb shell
cat /proc/partitions
This one needs from you to figure out which block belong to which partition name.!!
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Way #2
Code:
adb shell
ls -al /dev/block/platform/[B][COLOR="Blue"]dw_mmc[/COLOR][/B]/by-name
This one will give you info about the dev block names WITH their familiar names (i.e, boot, recovery, system... etc)
This command is not universal between devices, and you will need to gather its pieces (/dev/block/platform/dw_mmc/by-name).
How?
- In your device, use any explorer that can get you to the device root (personally I use ES Explorer, by pressing on "/" on navigation bar).
- Go to "/dev/block/platform/" folder
- Here you will see some files and folders, we need to open folders and search for the folder called "by-name" inside one of them; in my situation it was "dw_mmc" folder which has the folder "by-name" inside it.
- At the end, my targeted piece info will be (/dev/block/platform/dw_mmc/by-name)
- Now open adb shell and put that command..
Way #3
By pushing parted binary to /system/bin folder and run it (you can find it in attachment).
Code:
adb remount
adb shell "su" "" "mount -o remount,rw /system"
adb push parted /system/bin/parted
adb shell
chmod 0755 /system/bin/parted
parted /dev/block/[B][COLOR="Blue"]mmcblk0[/COLOR][/B]
print
Here, your mounting points will start with /dev/block/mmcblk0p* where (*) is the number shown in the table above for each partition.
example:
The hidden partition mounting point will be mmcblk0p10
The radio partition mounting point will be mmcblk0p7
The system partition mounting point will be mmcblk0p9
The recovery partition mounting point will be mmcblk0p6
and so on
Don't forget to "quit" the parted action after grasping your device mounting points.
N.B:
- You may need to run first:
Code:
adb shell
cat /proc/partitions
to know what is the initial name for your device partition.. In the example above, it was mmcblk0.
- Also to be able to do adb push to /system partition for parted binary, you will need insecure boot.img used in your ROM or adbd insecure installed in your device (Check this thread for that app), or just push parted binary manually by any root explorer and then fix permissions to rwxr-xr-x (755).
***​
Section 2:
Dumping ROM partition​After locating the mounting point of the partition you want to dump, open adb shell command prompt and type:
Code:
adb shell
su
dd if=[B][COLOR="Blue"]/yourMountingPoint[/COLOR][/B] of=[B][COLOR="Green"]/yourDestination[/COLOR][COLOR="Red"]/partitionType[/COLOR][/B]
Let's say I want to take a dump out of system partition from above example. So the adb commands will be:
Code:
adb shell
su
dd if=[B][COLOR="Blue"]/dev/block/mmcblk0p9[/COLOR][/B] of=[B][COLOR="Green"]/sdcard[/COLOR][COLOR="Red"]/system.img[/COLOR][/B]
This may take a while to complete the dumping process, depending on the size of your dumped partition; so be patient..
Note:
If the partition is formatted as ext3/4 then the dumped partition will have .img as an extension.
Other partition dumps have different extensions; examples:
radio.bin
param.lfs
Sbl.bin
zImage (without extension)
***​
Optional:
Read Partition Image​After dumping an image from android partition, you can mount it to extract a particular file for sharing, or the whole dump content in case the ROM chief wants to make a ROM out of dump files..
For Linux Users:
- Open terminal and type:
Code:
su -
mkdir -p /mnt/disk
mount -o loop [B][COLOR="Red"]yourImage.img[/COLOR][/B] /mnt/disk
cd /mnt/disk
ls -l
For Windows Users:
- Download LinuxReader from this site here.
- Open it -> Drives -> Mount Image -> Then choose your dumped image and hit Mount. A new driver will appear that contains all files inside the dumped image called "Linux native Volume 1". Just double click it to get inside the dumped image.

Actions Explanation
★ Tutorial Legends ★​
In this post, I will try to explain the use of each binary used in the tutorial, so you can make sense of each action taken.
#1
Code:
adb shell
Run remote shell interactively, as if you are in linux terminal.
Click to expand...
Click to collapse
#2
Code:
cat /proc/partitions
cat binary is used to concatenate file(s) and print them to standard output display. In our example, it prints the content of partitions file which is found in proc folder to screen display.
Click to expand...
Click to collapse
#3
Code:
ls -al /dev/block/platform/dw_mmc/by-name
ls binary is used to list directory contents.
-al is the used option for ls which means to include entries that started with "." in long listing format. There are a lot of options for ls binary. You can always print ls --h to display help menu for other options available.
Click to expand...
Click to collapse
#4
Code:
adb remount
Remounts the /system partition on the device read / write. This has been disabled in some devices (those with secure boot image); so you need to make sure that you have patched adbd that can run this command effectively.
Click to expand...
Click to collapse
#5
Code:
su
Used to get super-user privilege.
Click to expand...
Click to collapse
#6
Code:
mount -o remount,[B][COLOR="Red"]rw[/COLOR][/B] /system
Specific command to mount the /system partition on the device read / write (rw).
If you change rw to ro, you will get /system partition mounted as read only.
Click to expand...
Click to collapse
#7
Code:
adb push parted /system/bin/parted
adb push is used to copy file/dir from your local computer to android device. The usual format is adb push <local> <remote>
Click to expand...
Click to collapse
#8
Code:
chmod 0755 /system/bin/parted
chmod binary is used to set permissions for the specified file/dir.
The number after chmod is the permission used. See the next box for better understanding of chmod formatting:
Code:
[CENTER][B][COLOR="Red"]----------------
| CHMOD SCHEME |
----------------[/COLOR][/B][/CENTER]
[B] r w x[/B]
[B]4 2 1 [COLOR="Green"]= 7 (Full Permissions)[/COLOR][/B]
User ( ) ( ) ( ) [B][COLOR="Green"]--> 2nd digit[/COLOR][/B]
Group ( ) ( ) ( ) [B][COLOR="Green"]--> 3rd digit[/COLOR][/B]
Other ( ) ( ) ( ) [B][COLOR="Green"]--> 4th digit[/COLOR][/B]
Special UID GID STK
( ) ( ) ( ) [B][COLOR="Green"]--> 1st digit, ignored on most cases or put 0[/COLOR][/B]
In the above example, it is set to 0755 which means the following scheme:
Code:
[B] r w x[/B]
[B]4 2 1[/B]
User ([B][COLOR="Red"]*[/COLOR][/B]) ([B][COLOR="Red"]*[/COLOR][/B]) ([B][COLOR="Red"]*[/COLOR][/B]) [B][COLOR="Green"]--> This equals to 7 (rwx)[/COLOR][/B]
Group ([B][COLOR="Red"]*[/COLOR][/B]) ( ) ([B][COLOR="Red"]*[/COLOR][/B]) [B][COLOR="Green"]--> This equals to 5 (r-x)[/COLOR][/B]
Other ([B][COLOR="Red"]*[/COLOR][/B]) ( ) ([B][COLOR="Red"]*[/COLOR][/B]) [B][COLOR="Green"]--> This equals to 5 (r-x)[/COLOR][/B]
Special UID GID STK
( ) ( ) ( ) [B][COLOR="Green"]--> This equals to 0 (---)[/COLOR][/B]
As you can see, if you said 0755, it will be as same as saying ---rwxr-xr-x

Code:
dd if=/dev/block/mmcblk0p9 of=/sdcard/system.img
dd binary is used to copy a file with converting and formatting.
if means input file; here we pointed to the whole partition, not specific file.
of means outputting file to specific destination path; here it is to sdcard with system.img name.
Click to expand...
Click to collapse
#10
Code:
mkdir -p /mnt/disk
mkdir binary is used to make folder dir.
-p is mkdir option which means to create folder with sub-folder at the same time. Here we want to create mnt folder that contains disk sub-folder in it. If the folder and or sub-folder(s) are already exists, it will not give error but nothing will be created.

#11
Code:
mount -o loop yourImage.img /mnt/disk
This is linux way to mount images into specific directory (/mnt/disk in this example).
Click to expand...
Click to collapse
#12
Code:
cd /mnt/disk
cd used to get inside specific dir path.
Click to expand...

#13
Code:
ls -l
ls binary is used to list directory contents as described above.
-l is the used option for ls which means to list contents in long listing format.

another way to get common names
on way #2, I've often used:
Code:
cat /proc/emmc

can i able to mount boot.img in android itself...actually i wanted to extract boot.img frm mobile without any tools or without the help of PC...if there be any possibilities..??

if you mean extract to modify boot.img, then I don't think there is away to do that from device itself in the moment..
if you mean dumping boot.img then yes you can, just install terminal emulator from Google play and you can run adb shell commands directly from the device
Great guide hopefully makes it easier for us to get dumps! if you add logcats etc, i find they have trouble executing "adb logcat >> log.txt" -.-
also you should teach them the easy tar method, so while booted "tar -c /system/* >> /sdcard/system.tar" or via adb shell

Yup that is possible and easy to extract but it is only for partitions that is shown in android os,,, you can't use it for boot.img, sbl.bin, modem.bin...etc right

ofcoarse, i actually had a project going where it detects all partitions(modems, boot.img, system etc..) that archives itself into a .zip
it was going well until i did something in the script, now it only works on the s3 it shall be continued one day!
Such great tutorial, this is definitely going to come in handy for me. I have a question, how can you dump (extract) a bootloader? Can i use the same method as dumping the ROM?
Could you explain how to extract stock recovery image please?

Thx for this. On my HTC One there is no "by-name" folder. It only has "by-num". cat /proc/emmc works fine though.
Cheers.
I also wrote a guide, It just using the "by-name"
and needs root
[HOWTO] dump your rom
Code:
dd if=/dev/block/platform/msm_sdcc.1/by-name/system of=/storage/extSdCard/system.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/recovery of=/storage/extSdCard/recovery.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/param of=/storage/extSdCard/param.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/boot of=/storage/extSdCard/boot.img
Hi,
I tried this on my I-9505G. It is NOT rooted, so I thought I could enter the system through Clockworkmod Recovery.
I did it, but at first I didn't mount the DATA partition (later on I did through CWM Recovery); I still ran the command:
dd if=/dev/block/platform/msm_sdcc.1/by-name/system of=/data/media/TEST/system.img
Thought I hadn't mounted anything, the media folder was still there, I only created the TEST folder.
After the image was created I typed the "ls" command and the system.img file was in /data/media/TEST/.
I then rebooted once again in CWM and ran the "adb shell" command once again, I entered /data/media/ e neither the img file nor the TEST folder I had created were there.
My question is: where have they gone?? Are they still occupying some of my space or they just got deleted automatically when I rebooted??
Please let me know as I'd like to free that extra unuseful 1.2 Gb system.img file.
Anyway, just as side information, I later on mounted the /data through CWM interface and was able to see the folders ("/data/media/0/") I can see by plugging the phone normally to the computer. I then dumped the image.
I have some other questions:
I can I mount the /data folder (or the external SD) via command?
What extention should I give to the other partitions? (All of them)
Why did you say that it's MANDATORY that the phone be rooted if it can be done this way?
Are the images I'm dumping flashable through fastboot?
Thank you all for your time!
Anybody? Please.
•I can I mount the /data folder (or the external SD) via command?
I have not been able to find the SD card in clockwork on the I9505G, hence one of my rooting procedures send the root file vi "adb sideload".
I might be able to pull the data from the phone but the clockwork recovery is still not working 100% when fastbooting it.
•What extention should I give to the other partitions? (All of them)
.img are fine.
•Why did you say that it's MANDATORY that the phone be rooted if it can be done this way?
currently it is required that the phone be unlocked. Something need to be fixed in clockwork to make it work any other way.
•Are the images I'm dumping flashable through fastboot?
They should be, but I have not been able to flash anything on the I9505G vi fastboot because of the secure boot.
without a full official image this make my playing around a little concerning (slowing me down).
I will look into this at my leisure. I would love to be able to pull a rom off a phone with only unlocking it.
I will test some stuff using my old galaxy nexus.
I actually dumped everything WITHOUT being rooted. I only unlocked the bootloader... So it works.
Further, I tried to run "fastboot boot recovery.img" with recovery.img being the image file I dumped. The phone froze and I had to pull the battery... So I assume they're not flashable as well, though I'd like other feedbacks.
I've not clearly understood what "secure boot" means. Any guide or wiki?
Thanks!

Hey, great guide! I need some help but. I can't retrieve the common names / labels of my devices partitions. It's a GT-i8150 and there is no 'by-name' sub directory. Furthermore, parted does not work on mmcblk0 for some reason (unable to satisfy partition restraints or something). I also have no emmc file in proc.
Does anyone know how some other methods for getting the names of the partitions?
EDIT:
Another question - using ADB shell, is it possible to dump a partition straight from the phone onto the computers hard drive? My little 2GB sd card isn't coping! Thanks
a very basic but good guide
