Getting root

Hi!
First post, but I've got a few things nailed down right through searching the forums and various guides and wiki's.
I've managed to install Google ION with firmware v1.5
I've SIM-unlocked the phone, using another carrier works splendid.
The Kernel version i'm using is 2.6.25.00894-g83efb08-dirty
[email protected]
My build number is CRB43
What I'm trying to accomplish here is getting root on the filesystem. I've tried various methods, guides and forum conversation tips but I can't make /system anything else than ro (Read-only).
I have installed Better Terminal from Market.
su and telnetd works perfect, I can connect to the phone using telnet. I'm using telnet to connect to the device, by forwarding ports through ADB.
I have tried using ADB shell to get root as well as telnet.
What I am trying to do is replace my current keymapping from an English one to an edited, åäö-capable one, because it's damn tricky trying to type these characters on the hardware keyboard. I haven't even found a way of typing åäö without replacing the keymap because of very little information about how the keyboard _is_ mapped using Android on the Kaiser.
Please advice wither on how to be able to type åäö characters without having to modify the keymap or give me a heads-up on how I'm supposed to get root on this filesystem, using commands such as;
# mount -o rw,remount /dev/block/mtdblock3 /system
does not give me an error but nothing else is returned either so I can't verify that the command actually executed or did anything to the system. I can however verify that the /system is still ro and still as a cramfs type no matter how I attack this.
Here's my situation on my mounts;
Code:
rootfs on / type rootfs (rw)
/dev/block/mmcblk0p1 on /sdcard type vfat (rw,noatime,nodiratime,fmask=0000,dmask=0000,codepage=cp437,iocharset=iso8859-

[Q] Mount /system in R/W

Root Explorer is unable to re-mount /system in R/W. The button simply does nothing when I press it. I am also unable to update AdFree, which re-writes the hosts file in /system. Anything I can do to remedy this?

stupid question, but I have to ask: are you rooted?

Try backing all the way out of the folder by pressing the (...) button at the top. Keep pressing that until you are at the root folder (it won't be there anymore). Now press the r/w button at the top. It should change, and will stay changed once you go back into the other folders.

Sorry, it was early, and my brain wasn't good for specifics. I am rooted, running SRE 1.2.
Root is mounted R/W, but /system will not change state. Is there anything I can try from the terminal?

Same problem here on my wife's Captivate. I used SRE 1.2.1a and noticed that I was still seeing ads. So I tried installing Adfree and updating the host file and ran into the same mounting error.
On my own Captivate, I had used 1-Click root before SRE came out and no problems updating there.

same here no ADFREE in SREv2b7. I tried R/W on Root explorer and even trying to change permissions on sys,system, data/data, and still get same error as you guys re-mount /system.

Let's see where /system is mounted:
Code:

At this point, we can see that /system is mounted at /dev/block/stl9. With that knowledge:

Now your free to do whatever it is you were trying to do. When you're done, don't forget to:

I can't update AdFree either.

Didn't work for me either--still got the "failed to mount read-only file system" or something like that. Also, when I tried the "-o remount,ro" adb said device or resource busy. I'm pretty sure this has been discussed in the SRE thread, but i really, really, want adree to work

system dump

Hey guys,
Here's a dump of /system from the Google I/O GT10.1. Let me know if there's anything else you're interested in.

Thanks mate. Can you dump boot and recovery as well? Not even sure if you can, but...

I could if I knew where they were. Someone more knowledgeable than I would probably know where they usually are. Unfortunately, I cannot search the device because most standard commands are not available(find, grep, etc.)

Cool. Thanks.
Have you tried adding busybox? Im surprised that the root 'package' didn't include them. I think Titanium Backup will add it for you but not the symlinks AFAIK so you need to prefix each command with busybox. eg:
Code:
busybox chmod +x <file>

it won't let me create a link to /system/bin/ because it's stuck at read only. I created a thread about this already, but does anyone know how to remount /system? I've tried the standard ways and they don't seem to work

This worked for me:
mount -o remount,rw /system

If all else fails, use Root Explorer to remount /system

Just thinking "out loud" here, but would it be fair to say that if someone could extract the boot and recovery images from these google 10.1's that they could be flashed onto a 10.1v with Odin or fastboot and allow the 10.1v to be rooted in the same way as the 10.1g?

That's what I'm hoping

wow, that was stupid of me. I was trying

but obviously that isn't needed.
Thanks

alright, so I have busybox working
but all the tutorials I've found have said to use
cat /proc/mtd
to find out what to pull but for me, it just returns
dev: size erasesize name
also, they say to use
cat /dev/mtd/mtdX > /sdcard/mtdX.img
but /dev/mtd doesn't exist on this device
any ideas what I could be doing wrong?

Stupid question, but you did do a
Code:
su
before running these commands?
Sometimes it's the simple things

it certainly wouldn't be the first time I'd missed something as blatantly obvious as that, but no I did remember this time. That's not to say that I'm not missing something else that should be completely obvious, but I did at least remember to run it as root.

Haha - yeah, Ive certainly been stumped by simpler things than that. Usually success if followed by a facepalm
Really appreciate your persistence with this!
Could you possibly post the output of:
Code:
adb shell mount
and
Code:
adb shell su ls -l /cache
You should see from this output which device is mounted as /cache and how the /cache/recovery is mounted/linked.

Rooting the Captivate using the command line under Linux

I've tried just about every automated/one click/whatever method for rooting my spiffy new Captivate, and they all failed for one reason or another. I finally got it to work using adb & the command line. Here's how I did it. Oh, and before someone asks "Why didn't you just use Windoze?", it's because all my computers run Linux so that's not an option.
STANDARD DISCLAIMER: If you root your phone, the ceiling will collapse on your head and your family will die. No one should ever follow these instructions. In fact, I should probably be banned for even posting them.
MY SETUP:
Ubuntu 11.04 (natty)
Samsung Captivate i897, stock, KB2
AT&T
1. Download SuperOneClick
http://forum.xda-developers.com/showthread.php?t=803682
I used 1.9.5, only because another poster told me he had successfully rooted his Captivate using that specific version. This may also work with the files from a newer version; I don't see why it wouldn't.
2. Extract everything
Duh.
3. Put adblinux, psneuter, busybox, su-v2, and Superuser.apk in one directory.
I don't know that it has to specifically be su-v2, but that one worked for me, so huzzah.
4. Put the phone in USB debug mode; plug it in to your computer.
Settings -> Applications -> Development (check the box for USB debugging). Linux users need no drivers.
5. Open a terminal, cd into wherever you extracted the SOC files.
6. Let's dance:
Code:
./adblinux push psneuter /data/local/tmp
./adblinux push su-v2 /data/local/tmp
./adblinux push busybox /data/local/tmp
./adblinux shell
$ cd /data/local/tmp
Make everything you just pushed over executable:
Code:
$ chmod 6755 psneuter
$ chmod 6755 su-v2
$ chmod 6755 busybox
Run the exploit:
Code:
$ /data/local/tmp/psneuter
Running psneuter successfully kicked me out of the shell, so go back. You should also notice when you re-enter the shell that your prompt has changed from "$" to "#", indicating psneuter was successful. This also means you have root privileges, at least temporarily, for the rest of your work.
Code:
./adblinux shell
# mount
"mount" should spit out something that looks like this:
mount
rootfs / rootfs ro 0 0
tmpfs /dev tmpfs rw,mode=755 0 0
devpts /dev/pts devpts rw,mode=600 0 0

On your phone, that output might look a little different, but you're looking for the line in BOLD. In the example above, "/dev/block/stl9" is the mount point for "/system". If "mount" gives you a different mount point, then use that in the commands below. The stuff after that tells you the properties of "/system"; "ro" is the one we're concerned with. That tells us that "/system" is mounted as "read-only". We need to change that so we can move some files over.
Code:
# mount -o remount,rw /dev/block/stl9 /system
"/system" is now writable. Let's move some files over.
Code:
# /data/local/tmp/busybox cp /data/local/tmp/busybox /system/xbin
# chmod 6755 /system/xbin/busybox
# /data/local/tmp/busybox chown 0.2000 /system/xbin/busybox
A functional copy of busybox now resides at /system/xbin, so from now on you can just call it with "busybox" instead of having to use the full path to the one we pushed over earlier.
Code:
# busybox mv /data/local/tmp/su-v2 /system/xbin/su
# chmod 6755 /system/xbin/su
# busybox chown 0.2000 /system/xbin/su
# busybox ln -s /system/xbin/su /system/bin/su
IMPORTANT: Do not leave your "/system" mounted as read-write; change it back and exit the shell:
Code:
# mount -o remount,ro /dev/block/stl9 /system
# exit
$ exit
You should be back at your basic Linux command prompt now. Install the Superuser app.
Code:
./adblinux install Superuser.apk
7. Reboot your phone
When everything loads back up, you should have root privileges. Update BusyBox from the market. If everything went according to plan, when you try to install BusyBox you should get a prompt from the Superuser app asking if you want to grant the BusyBox installer superuser privileges. If so, everything worked the way it was supposed to, and you're now a 1337 [email protected]><0r or something.
8. Troubleshooting
Mine didn't take the first time for some reason. After reboot, I installed BusyBox and Titanium Backup, both of which failed to get root privileges. I went back into the phone with adblinux, remounted /system as rw, again set the privileges for "/system/xbin/su" to 6755, then remounted /system as ro and rebooted. It took the second time, so I'm assuming I may have typed something wrong.
Another thing I was keen to try is installing the Superuser app FIRST, then running the hacks to root the phone. The phone does not need to be rooted to install Superuser, only for it to work as designed. I am curious if "SU->root->reboot" would work the first time, instead of "Root->SU->Reboot->Re-Root->Reboot", which is how it's been working now. If I happen to reinstall and try this again, I'll update. If anyone else gives it a whirl, post a comment and I'll update accordingly.
I hope this helps someone else. Please comment below with questions/criticisms/flames.

Thanks bro this is a very handy guide i to use only linux and it kills me how many people say ehh just install windows it easier BLAAA is what i say great work keep it coming...

I'm with you. I HATE hearing "just use Odin" or "you can buy a copy of Windoze for not much $$$!" If I wanted Windoze, I'd be using it already. If I could use Odin, I'd probably just follow the directions for that and not be asking questions about Heimdall.

+1 thanks. been running linux since 2002, wasn't looking forward to using a friends computer just to root a phone.

[Q] Read-Only internal storage?

Hi All,
(I've read tons of Threads here, but not yet found a solution).
My Galaxy Tab 10.1 is useless right now as it cannot write to internal storage.
Lots of apps crashing on use and doing a factory reset from the recovery menu does not help (Tablet is in exact same state aon reboot).
So, I've been using adb
Code:
C:\Program Files (x86)\Android\android-sdk\platform-tools>adb remount
remount failed: Operation not permitted
Here's the mount information from shell
Code:
[email protected]:/mnt/asec $ mount
mount
rootfs / rootfs ro,relatime 0 0
tmpfs /dev tmpfs rw,nosuid,relatime,mode=755 0 0
devpts /dev/pts devpts rw,relatime,mode=600 0 0
proc /proc proc rw,relatime 0 0
sysfs /sys sysfs rw,relatime 0 0
debugfs /sys/kernel/debug debugfs rw,relatime 0 0
none /acct cgroup rw,relatime,cpuacct 0 0
tmpfs /mnt/asec tmpfs rw,relatime,mode=755,gid=1000 0 0
tmpfs /mnt/obb tmpfs rw,relatime,mode=755,gid=1000 0 0
none /dev/cpuctl cgroup rw,relatime,cpu 0 0
/dev/block/mmcblk0p4 /system ext4 ro,relatime,barrier=1,data=ordered 0 0
/dev/block/mmcblk0p5 /cache ext4 rw,nosuid,nodev,noatime,barrier=1,data=ordered 0 0
/dev/block/mmcblk0p8 /data ext4 ro,nosuid,nodev,noatime,barrier=1,data=ordered,noauto_da_alloc,discard 0 0
/dev/block/mmcblk0p1 /efs ext4 rw,nosuid,nodev,noatime,barrier=1,data=ordered 0 0
/dev/fuse /mnt/sdcard fuse rw,nosuid,nodev,relatime,user_id=1023,group_id=1023,default_permissions,allow_other 0 0
So, I've tried to mount manually from adb shell:
Code:
[email protected]:/ $ mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
mount: Operation not permitted
[email protected]:/ $
[email protected]:/ $ mount -o remount,rw -t rfs /dev/block/stl9 /system
mount -o remount,rw -t rfs /dev/block/stl9 /system
mount: Operation not permitted
But, I have no SU command:
Code:
[email protected]:/ $ su
su
/system/bin/sh: su: not found
I've got the su binary from downloading off this forum, but I cannot copy that up either (even to seemingly writable mount points)
Code:
C:\Program Files (x86)\Android\android-sdk\platform-tools>adb push su /cache
failed to copy 'su' to '/cache/su': Permission denied
Any hints to what I can do now?

Hey, this forum is for Samsung Galaxy Tab 7.
Here is link for SGT 10.1
http://forum.xda-developers.com/forumdisplay.php?f=1050
But looks like your device is not yet rooted correctly.
The easiest thing is to find pre-rooted kernel and flash them via odin.

Thanks for the reply, yappoe!
I was following a guide I found linked on a forum to get the Tablet Restocked to factory settings.
However, when I try to write via Odin, I get an error message on the tablet in Red
Code:
Bct_sync_Odin: Error to NvBuBctUpdate![err:0x140005]
DownloadPartition_Odin: Error to Bct_sync_Odin![err:0x140005]
Tegra_Nand_Write: Error to DownloadPartition![err:0x140005]
Obviously a write error, presumably as the File system is in Read-Only mode ?

Yes, because permission is not set correctly. You need root access to do that.
I really don't know much about G-Tab 10.1, and I don't know what you were trying to do or are trying to do.
But if you are trying to go back to stock firmware, you can follow this steps.. it works on most Samsung. (Note: Unless you are moving from Honeycomb to ICS or vice versa, you do NOT need to re-partition).
you can download any official firmware at http://fus.nanzen.se/
1. Download Fus Check Downloader 2.1 and downloaded a Firmware for your region. It will automatically decode the .enc2 file to.zip file
(or find your firmware at sammobile.com, you can skip step 2).
2. Extract the .zip file generated from decoding file to a folder and I got
tar.md 5 file.
3. Start Odin - put the .md5 to PDA and leave everything else as is.
4. Go to download mode on the G-tab
and click start. It takes about 6 to 7 minutes to do the flashing.
Can't guarentee if it would work, but good luck.
Once you get it work with STOCK, go to the Galaxy Tab 10.1 forum
and find the instruction there to ROOT

Thanks yappoe,
That is a nice tool for firmware downloading.
Unfortunately I get the exact same error immediately when trying to write to the tablet via Odin.
Code:
Bct_sync_Odin: Error to NvBuBctUpdate![err:0x140005]
DownloadPartition_Odin: Error to Bct_sync_Odin![err:0x140005]
Tegra_Nand_Write: Error to DownloadPartition![err:0x140005]
I think I have a sort of chicken and egg situation where I my problem is my drive is mounted in read-only mode and I cannot change it without rooting/executing su
Ro

same situation
I have the same situation but with my omnia 2.
suddenly, the internal storage became read-only.
I have tried flashing the ROM and unchecking "preserve device contents".
I have tried spyware, malware, antivirus from PC via usb mode.
I have tried low-level format.
I have tried hard reset.
I have tried below cabs.

nueStorageManager-v1.1
Til now, i still have the problem.
Im using a micro sd instead.
Im planning on opening my phone and removing the internal memory chip instead lol.

I did open up my tablet.
The internal memory is part of a single mainboard.
(I think its the same in almost every device)
Looking into getting a replacement mainboard now.

It's possible to use an external SD card as the internal storage. This won't fix the internal storage, but your Tab will work again. See this thread.

Cheers for the pointer, but the Galaxy Tab 10.1 doesn't have a place for an SD / micro SD card addition.

Ah. But you asked in the wrong forum.
Go to Galaxy tab 10.1 forum

Yeah i asked a technician if he could do it, he said he has no idea where that chip is in the mainboard

The mainboard cannot have components removed/added ... You have to replace the entire mainboard.
