Hey all,
I had the sense to use the Rotobackup method on my new Sprint Tab after rooting it with the Z4root package. I then proceeded with the ( now outdated ) CWM Flash process adapted from the Epic 4g. Now, I can get into CWM and the process appears to be functional, but I can't get the "Wipe Data/Factory Reset" to work. It all goes well, but when I boot back into android, all the junk is still there.
Now, I know this wouldn't normally be a big deal... However.. In set'n up for my Rotobackup, I punched in a spare Gmail account in case someone wanted a copy of the backup for dissection,etc... Now, since I can't get the factory wipe to work ( neither from the Privacy menu, nor CWM ), I can't get that acct off my Tab so I can get to all my purchased apps on my main account.
Since I have the Rotobackup, I'm thinking that I can just restore one of those packages and get the stock recovery image back in place. I just want to verify which one I should restore before I move forward.
My expectation is that I need to restore the 'boot.bin' file. Can someone confirm this?
For the record, these are the files I have saved:
Code:
-rw-r--r--. 1 root root 262144 Dec 22 19:00 boot.bin
-rw-r--r--. 1 root root 32768000 Dec 22 19:00 cache.rfs
-rw-r--r--. 1 root root 25620093 Dec 22 19:23 data.tgz
-rw-r--r--. 1 root root 86507520 Dec 22 19:00 dbdata.rfs
-rw-r--r--. 1 root root 6553600 Dec 22 19:00 efs.rfs
-rw-r--r--. 1 root root 336068608 Dec 22 19:00 factoryfs.rfs
-rw-r--r--. 1 root root 16777216 Dec 22 19:00 modem.bin
-rw-r--r--. 1 root root 1310720 Dec 22 18:58 param.lfs
-rw-r--r--. 1 root root 262144 Dec 22 19:00 pit.pit
-rw-r--r--. 1 root root 1310720 Dec 22 19:00 Sbl.bin
-rw-r--r--. 1 root root 7864320 Dec 22 18:59 zImage
Thanks in advance,
LK
Or, can I simply do an rm -rf /data/* to get the effect of a factory wipe?
Thanks,
LK
Ok, I figured it out..
So, the thought of flashing the recovery image came from my root experiences on Evo. I decided while waiting for a response to do more digging through the CWM installation routine and noticed that it made a backup of the original recovery file ( since on Epic and Tab, it's a redirector method instead of an image on the Evo ). AND.. it had a 'Remove root/CWM' option!
I modified the run.sh script to NOT remove root on that option and only put the original CWM in place, ran it.. and VIOLA!
Hope this may help someone else.
LK
are you saying you have a working CWM running on your Sprint-flavored tab?
Hello Zoinks,
Nope... the CWM wasn't working properly on my Samsung Tab. I reverted to the stock recovery on my Tab to regain the ability to wipe it.
Thanks,
LK
and you were so close to being my new best friend
which modem are you using? we have not been able to properly export the factory modem
I'm afraid neither of us are that lucky.
I'm still using the original modem. Nothing has actually been flashed to the device aside from what it took to root it.
Nothing to see here...
LK
ok, so I also just rooted my new sprint tab. using the z4root method. I also have learned about rooting through my evo. I have not however got as far as you have as in getting a recovery image. If i understand what I have tried to absorb on this from the board, is that A) I should have gone with tmobile for the tab!!!! lol and B) this aint no EVO!!!!!
So could you point me in the right direction/advice with what I should do now, because I am lost!!!!
thanks in advance
I'd install bash with the 'Bash Installer' app from the market, and then any other goodies you like for rooted devices ( Adfree Android is a personal fav ).
Aside from that, hang tight and watch for more advancements in alternative ROMS and Recovery managers. Don't install any recovery manager at this time as they are too buggy for normal use and don't really have much in the way of usable features yet.
Clockwork Mod is the closest, but still doesn't support nandroid backup and the like.
Oh, also.. you should check into creating a 'Rotobackup' of your device per the instructions found in another thread of this sub-form.
Enjoy!

I'm having the same problem, can you tell me how to do that? Where's the run.sh file?
Thanks.
Hello zephyrd,
The problem I had was because I used the CWM process outlined in this thread. The 'run.sh' script is the one included with the downloads in that thread.
I edited the run.sh file as follows:
* FInd the section that starts with 'function remove {'
* Inside that section, find the following two sub-sections:
- echo Running root file cleaner on device
- echo Removing remount binary
* Comment out the lines under those sections with # so that the final 'function remove {' section looks like this:
Code:
function remove {
clear
echo +++++++++++++++++++++++++++++++++++++++++++++++++++++
echo "Simple Root and ClockworkMod Uninstaller 2.01";
echo +++++++++++++++++++++++++++++++++++++++++++++++++++++
echo Bash Scripts by DRockstar and Firon
echo exploit by joeykrim, original uninstaller by noobnl
echo
echo REMOVES ALL ROOTS AND CLOCKWORKMOD REDIRECTOR
echo MODIFIED FOR USE WITH GALAXY TAB
chooser
startserver
checkroot
echo Mount device RW
$adb shell mount -t rfs -o remount,rw /dev/block/stl9 /system
#echo Running root file cleaner on device
#$adb push rclean /system/xbin/rclean
#$adb shell chmod 755 /system/xbin/rclean
#$adb shell /system/xbin/rclean
#$adb shell rm /system/xbin/rclean
#echo Removing remount binary
#$adb shell rm /system/bin/remount > /dev/null 2>&1
#$adb shell rm /system/xbin/remount > /dev/null 2>&1
echo Removing ClockworkMod redirector
$adb shell rm /system/bin/recoveryfiles/*
$adb shell rmdir /system/bin/recoveryfiles
$adb shell rm /system/bin/recoveryres/images/*
$adb shell rmdir /system/bin/recoveryres/images
$adb shell rm /system/bin/recoveryres/*
$adb shell rmdir /system/bin/recoveryres
$adb shell rm /system/bin/recovery
echo Restoring original recovery file
$adb push recovery /system/bin/recovery
$adb shell chmod 755 /system/bin/recovery
echo Rebooting phone
$adb reboot
checkboot
echo
echo SIMPLE ROOT UNINSTALLER COMPLETED.
end
}
When you run the 'run.sh' command, pick the 'Simple Root and ClockworkMod Uninstaller' option. This will restore your recovery manager back to the stock one, while leaving your Tab rooted.
NOTE: This same logic can be applied to the 'run.bat' file. The sections that need to be commented out are the same. Instead of using a # to comment the lines, place the word 'REM ' in front of them.
The run.bat 'remove' function will look as follows when done:
Code:
:remove
cls
echo +++++++++++++++++++++++++++++++++++++++++++++++++++++
echo Simple Root and ClockworkMod Uninstaller 2.01
echo +++++++++++++++++++++++++++++++++++++++++++++++++++++

adb push recovery /system/bin/recovery
adb shell chmod 755 /system/bin/recovery
echo Rebooting phone
adb reboot
call :checkboot
echo.
echo SIMPLE ROOT UNINSTALLER COMPLETED.
goto :end
If you have any questions, please let me know. It's better to ask now than screw up your tab.
Hope this helps!

Thanks so much for the help! However, this doesn't solve my problem, which is outlined in this thread.
I think my factory setting is modified somehow and can not be removed.
I don't expect any solutions any time soon but if you think you can help I can provide more info on the problem.
Thanks again!

Can you give me a guide to follow to
A. Return to stock: titanium back up on sd card. Unfortunately no way to get titanium bac on tab as market has disapeared. Unless I can down load .apk and then install from card.
B. Replace voodoo kernal with different one that restores screen rotation, market etc.

hey guys i'm trying to copy my efs partition using adb shell using ramads code
"cd c:/your_ADB_directory_name/platform-tools (Use cd c:/your_ADB_directory_name/tools if you are using an older ADK versions)
adb shell
su
cp -r /efs /sdcard/efs
exit
exit"
I get to the *cp -r /efs /sdcard/efs* and it spits out a million and one errors saying it can't create any of the files due to there being no space.
my phone storage has 1.65gb and my SD has 8.3gb free of space so i'm quite puzzled by why it's saying this.
Check my thread to see if it helps...

Hey Guys i'm trying to do the network unlock on my captivate, its rooted but when i do the command cat /sdcard/nv_data.bin >> /efs/nv_data.bin it comes back with not enough space.
so than i df efs and i get:
EFS: 6064k total, 6064k used, 0k available (block size 1024)
so than i ls efs and i get:
nv_data.bin
nv.log
imei
so since i am replacing the nv data anyways i figured i could remove the nv_data in hopes of clearing space so I do rm nv_data.bin and it comes back with:
rm failed for nv_data.bin, Read-only file system
can somone help? would my method of thinking even work?
thanks
edit would it work if i did
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# rm /efs/nv_data.bin
edit 2:
so i found out that when i removed it through adb it worked, but maybe the edited nv_data file is bigger than the original?
this is what i did to check
- adb shell
- su
- rm /efs/nv_data.bin (no error)
- ls /efs (did not see nv_data.bin in there)
- cat /sdcard/nv_data.bin >> /efs/nv_data.bin (gave me the no space error)
what can i do now?
Talk about timing - your second edit made my post pointless.
Just to satisfy my curiousity, why are you using the cat command? Wouldn't it make sense to cp /sdcard/nv_data.bin /efs/nv_data.bin, as there isn't an nv_data.bin file in /efs to use the cat command on? (My CLI commands are a little rusty, I'll admit...)
If you're using a rom with CWM, try rebooting to CWM and accessing the phone from there first. In my experience, adb access from CWM gives you the read/write permissions you'll need.
Also, if you're trying to replace the nv_data.bin file, I think the commands in adb be:
adb root
adb pull /efs/nv_data.bin (backing up current)
adb shell
rm -i /efs/nv_data.bin
cp /mnt/sdcard/nv_data.bin (or /sdcard/nv_data.bin)
(ls /efs to confirm)
Or something like that?
thanks for the advice, but I ended up just doing a factory reset and redid the whole process and it worked.
Hey all
I have the same error message. when i ls efs i had few more files in there than the OP they are
nv_data.bin
imei
nv.log
cryptprop_onetimeboot
cryptprop_securewipedata
nv_data.bin.md5
this to try putting the original nv_data.bin file back. Id like to put the a modified one which im hoping will let me unlock my captivate.
thanks
this is how i did to fix md5 missmatch due to restore from feamod recovery
-firstly make a folder clockworkmod/backup/2011-12-16.12.56.43 IN INTERNAL SDCARD
open terminal emulator
type su
#cd / sdcard/clockworkmod/backup/2011-12-16.12.56.43
#rm nandroid .md5 (if u get this rm failed for nandroid. read-only file system just leave it)
#md5sum *img > nandroid.md5
reboot to recovery
restore from internal
Good idea to post that (used it too with some backups). If you can't get into your device (bootloop etc) you should be able to do it on your pc. I tried doing it with md5sum (see attached) but it then adds an extra x0D (carriage return)... so if someone knows how to do this, please add to this topic
Regards,
Nika.
Thnx. can be very usefull
I have ca. 3 archives where I get md5 mismatch only one is restorable. Only for understanding do I only create an empty folder and make this or must I use the backup folder from my backup ?
Thx in advance

Please explain what you mean. You have 3 backups that give you this error? Then you should go to each of those backup-folders and run "md5sum *img > nandroid.md5" (without the quotes off course). This will regenerate the md5 file and then the restore should work if the backup files are intact (I've had some backups with 0 kb files too)
..I tried and get "bad substitution"
Dontron
Edit: I renamed the folders and now I can use the command..give a try.

You want to do it automatically through ADB? Here's a script:
Code:
@echo off
set FixMD5backup=[COLOR=Red][B]/mnt/sdcard/clockworkmod/backup/011-12-16.12.56.43[/B][/COLOR]
echo cd %FixMD5backup% >FixMD5.adb
echo pwd >>FixMD5.adb
echo ls -l -a * >>FixMD5.adb
echo chmod 666 nandroid.md5 >>FixMD5.adb
echo rm nandroid.md5 >>FixMD5.adb
echo md5sum *img *tar ^>nandroid.md5 >>FixMD5.adb
echo ls -l -a * >>FixMD5.adb
echo cat nandroid.md5 >>FixMD5.adb
echo exit >>FixMD5.adb
adb -d shell <FixMD5.adb
del FixMD5.adb
pause
Make sure the path is correct

If you are using a back from your sdcard, you will need to mount r/w.
Here is what I did, and it worked perfect.

For reference, attached is md5.exe and dos2unix.exe.
Here's the script to execute md5.exe (see attached) and make the nandroid.md5 on your pc:
Code:
@echo off
del nandroid.md5
for %%i in (boot.img,cache.ext4.tar,data.ext4.tar,recovery.img,system.ext4.tar,.android_secure.vfat.tar) do md5 %%i>>nandroid.md5 && echo %%i>>nandroid.md5
dos2unix nandroid.md5
pause
Btw, for everyone good to know, you can always run the md5sum from adb in clockworkmod recovery too (just before doing the backup, even when you're in the backup screen!):
Code:
adb shell
# cd /sdcard/clockworkmod/backup/[B]BACKUPDATE[/B]
# rm nandroid.md5
# md5sum *img >nandroid.md5
# exit

Nika.

Can you first check the filesize of each file that the backup created? If there's 0kb files you will not be able to restore them, do it with Advanced Restore one by one and you may be able to get back stuff...
If you don't know how to use the files I uploaded, I doubt a guide will help you

That does not seem like a complete backup. Normally you also have a system.ext4.tar, data.ext4.tar and cache.ext4.tar. I guess this backup failed.
The only things you have is a kernel (boot.img) and the recovery.

i am newbie
sorry for my question :
i have 03 clockworkmod backup in my ext_sd card named :
1 - 2012-05-08.16.48.10
2 - 2012-05-08.16.17.27
3 - 2012-05-02.02.25.41

1 - nitrox
2 - moon
3 - kqb
but when i try to restor i have md5 mismatch for all them
how to do for fix them all
please
EDIT : i finally understund the way :
i have moved clockworkmod from external_sd to sdcard
put the phone in usb debug
and than call adb shell with this :
adb shell
$ su
#
# cd /sdcard/clockworkmod/backup/nitrox
# rm nandroid.md5
# md5sum *img >nandroid.md5
# cd /sdcard/clockworkmod/backup/moon
# rm nandroid.md5
# md5sum *img >nandroid.md5
# cd /sdcard/clockworkmod/backup/kqb
# rm nandroid.md5
# md5sum *img >nandroid.md5
# exit
and then move back the clockworkmod to extrenal_sd and now all my backups work fine
thank you very much

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 pointsThere 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 partitionAfter 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 ImageAfter 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).

#12
Code:
cd /mnt/disk
cd used to get inside specific dir path.

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
