UnRoot Galaxy Tab 10.1 4G LTE with ADB Commands - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

Can someone knowledgeable please submit a detailed post, which instructs how to remove any files added during the Root Process, as well as any other file permission changes or modifications of any other type?
I see many half assed posts in these forums made by unqualified members, which are nothing but a waste of time and clutter this great resource. I would appreciate it if this post could be addressed by those who truly understand this process.
The file that was used to Root the SCH-i905 from Verizon was the one attached to this post.
Thanks in advance! This could be a great learning tool if answered properly.

Can some one please respond? Or is it that everyone is too scared to post helpful information?

Well, since no one was of any assistance, I was forced to piece together information and come to an understanding of how this works, and how to fully reverse what was done by this Root Update.
To begin, I would like to mention, that removing Superuser.apk from the /system/app folder, along with 'su' from the /system/bin folder, will negate your Root Access, and put you back to your default levels of access. This will prevent Mobile Device Management Solutions, such as AirWatch, Zenprise, or MobileIron from detecting your device as being compromised.
I was not successful in removing these two files via the ADB shell, however I was successful when using a Terminal Emulator App on the Device itself.
1.) I began by installing a free Terminal Emulator from the Android Market.
2.) Launched the Terminal Emulator and typed 'su' , then pressed Enter to gain Root Shell Privileges.
3.) From the Root Shell, I typed the following commands to remount the '/System' Directory to gain Read/Write Access.
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
4.) I typed the following commands to remove 'Superuser.apk' and 'su'.
cd /system/app
rm Superuser.apk
cd /system/bin
rm su
5.) Type the following command to remount the '/System' Directory back to Read Only.
mount -o ro,remount -t yaffs2 /dev/block/mtdblock3 /system
6.) Sync your device with Google under Settings / Accounts & Sync.
7.) Reboot your device, and you are good to go.
It might be a good practice to perform a Factory Reset on your device after doing this, however this is not completely necessary. I tested the Air-Watch Agent installation after performing the procedure mentioned above, and the Air-Watch console no longer detected my device as being compromised.

I will add that on my sch-i905 I found the bin directory under system not under system/app. For me, replacing cd /system/app/bin with cd /system/bin did the trick but the rest worked a treat - thanks for the post!

Thanks for pointing out my typo. I corrected the path in my Post.

Thanks for this.
Does this restore the stock recovery that was replaced with Clockwork when the kernel.zip and recovery.zip files were flashed to obtain root? I do not totally understand the relationship between Superuser and CWR. I found a reference to a flashable stock recovery in post 14 here http://forum.xda-developers.com/showthread.php?t=1205639&page=2 , but I'm unclear on the instructions.
I'm trying to understand how, if possible, to return my VZW LTE Tab to out-of-the-box stock, if desired.
Rooted: Droid Incredible / Droid X / Thunderbolt / 3G-4G Xoom / Galaxy Tab 10.1 LTE

I have the Superuser icon showing up in my apps folder, but I don't appear to have root access. I can't su in the terminal emulator nor can I load apps that require root access. I also tried removing the Superuser.apk via a file manager with no luck.
Any idea how to remove this thing if I don't actually have root access?

OK, I rooted again and fixed whatever was broken. Then I was able to apply these commands to unroot the device.
Thank you!

Stock Recovery isn't required to Root the device. However, if you wish to install CWM via ROM Manager from the Android Market, Root Permissions are required.
If you use an ODIN Flash of CWM, there is no need for Root Permissions because you are flashing via ODIN.
The stock recovery zip file that you referenced in the other post should be fine.
Just use ODIN to Flash back to Stock Recovery and use the process that I mentioned to remove Root Permissions and Super User, and you should be all set to return your device after a Factory Wipe.
Cheers!

Scott,
I'm sorry for just seeing your post. I'm sure that you figured it out by now. You need to gain Root Access to your device again to remove Super User. You are in a Catch22.
If you are using an SCH-I905, Root your device, then download Script Manager from the Android Market.
Run this very simple Bash Script that I wrote to remove Root and Super User.
Paste this into notepad and save it as Unroot.sh then run with Script Manager.
Code:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
cd /system/app
rm Superuser.apk
cd /system/bin
rm su
mount -o ro,remount -t yaffs2 /dev/block/mtdblock3 /system
Be sure to run the Script as Root from within Script Manager. The app will kind of freeze up as soon as it runs, which is normal. This will certainly take care of your problem.
Thanks for your post of stockrec in a different post. You saved me a month ago with that one.
Cheers!

Will Samsung know if I rooted my GT 10.1 LTE after using these commands, and sending in for warranty?

Does anyone know how often airwatch checks for the root? anyway to bypass the checks?

Is this the same for the US Cellular 4G Tablet? I have been reading and all that I have found was WiFi only files. Which if I were to root with those I lose the 4G radio.

Perfect.. Just what I need. Thanks

[Q] Rooted or not?

Hi, I rooted my Vribrant, both ways (manually and with one click root). I installed terminal emulator. I tried the su command to check if I am root. The # appears normally. However I tried deleting a file with Root explorer, inside the system folder, and when I get back it's still there. I also tried deleting it manually from Terminal EMulator with these commands:
su
cd system/apps
rm Swype.apk
and I get this:
rm failed for Swype.apk, Read-only file system
I also tried:
su rm Swype.apk
and this is returned:
Permission denied.....
I also tried the exact same thing from adb shell (which I had to allow in superuser permissions program), but it gave me the exact same results. What's wrong? Am I doing something wrong? Thanks
In root explorer, try hitting the r/w button at the top and see if that works.
Sent from my SGH-T959 using XDA App
I know about the button. The strange thing is that inside system folder it grands me r/w permissions, and no matter how many times a press the r/o button it doesn't change. Still gives the results I said. However, besides root Explorer what's wrong with terminal emulator and adb?
I'm not 100% sure how to mount as root in adb. I wish I knew myself heh.
Did any of those root methods install the superuser app?

I tried the first method but it didn't work. When I entered adb root, it said "adbd cannot run as root in production builds". I searched a bit and found that I must have a rooted kernel for this to work. (I guess it's different from the root method I tried in "how to root vibrant").
Anyway the second way worked, where i replaced mntblock3 with stl9 for my phone. I tried the rm command and it worked! However as soon as I exited terminal, I couldn't delete other files. I had to retype the command. I can't do this everytime I need access in System folder. Why is this happenning? Does this have something to do with the fact that root explorer cannot change r/w to r/o mode while in system folder?
what if you open Superuser
Click on Root Explorer.
Click on Forget.
Open Root Explorer and grant Root Access and check to remember it.
work now?
Moved to Q&A, please post in the correct section.

No it didn't work. I also installed the latest version of SuperUser 2.3.6.1. But without a difference unfortunately.
What works for me, is installing sgs tools, and whenever I want to do write operations on system folder, run the appropriate script from sgs and then use root explorer......
Although I think there's something wrong? Why doesn't the mount r/w button work in root explorer, and why do I have to remount the file system through SGS tools, every time for it to work?
makes no sense to me either. Have you uninstalled RE and the installed it back granting root once reinstalled?
Yes several times.....
I am giving up. I just have to go through the whole process every time. I found some other people having this issue. I am on stock JI6 firmware. Maybe when I read a little bit more I will flash a custom rom.
Download and install Super Manager. Pretty handy program to use for Root users.
I'm not sure what the issue is,but mine does it too. I'm running the "unofficial" froyo JK2 build,flashed via ODIN,and I'm having the same issues. root works,root file explorer is stuck in rw,won't let me switch to ro,and it can't do anything to files in / or /system. manually remounting it from terminal or sgs tools works.

At least I am not the only one with this problem.... haha
I forgot to mention that I use Root Explorer version 2.12.2
When I try a custom Rom I will post the results....
^ why not get the update, .4 is the most recent build. Do you have an illegal copy?
It's not only root explorer. It happens with other file explorers too like android mate and super manager... Inside system folder whatever, I do doesn't happen unless I unmount and remount like before

[Tutorial] Root Your EVO3D with Automated Scripts

Simple to use. Useful for those who want ROOT access via ADB or Device for Backup, etc. It is a modified scripts from Doomlord and some1 in the CDMA threads...
Prerequisites
1) Uninstall all HTC Sync & Drivers
2) Download and install http://downloads.unrevoked.com/HTCDriver3.0.0.007.exe
3) Make sure your device Display is set to NEVER TURN OFF & not locked in the lockscreen
Instructions
1. Download attachment
2. Extract to C:\
3. Execute file Step 1
4. Execute file Step 2. If doesnt work, go to C:\files and execute Step 2
5. Remount SD card again from the DEVICE SETTINGS page
This will work for all devices not limited to EVO 3D.
For locked bootloaders (any versions), this will result in a temporary ROOT access, and will be lost after reboot.
Please feedback for whichever H-Boot this works on.
Thanks to our following comrades...
Team Revolutionary with their ZergRush exploit
http://forum.xda-developers.com/show...1296916&page=2
DoomLord with the automated script
http://forum.xda-developers.com/show....php?t=1321582
For the third guy I cant remember where.. maybe the CDMA section with the permatemproot stuff..
With this script, Titanium Backup and Root Explorer will definitely work even on LOCKED bootloaders (will lose root after reboot, just rerun the script)
For problems especially with SUPERUSER FCs, please download and run the .bat file in the UNROOT.zip. This will clean the system of all old temp root stuffs like superusers, etc...
Appreciate your thanks..
i dun understand why but it didn't work as did ur last tool, it always saids adb server out-of-date, re running or sth, it does the same in every step, and when it comes to moving files/manipulating permissions, i just get loads of errors
I'm on HBOOT 1.49.0012
P.S. i cant unlock using HTC Unlock method too no matter how many times i try (i read the instructions carefully and followed them closely) but still got unlock token check failed error......

Reboot your device and try again... see edited post above..
Not sure about HTC Unlock method...
For UNLOCKED evos, it will give permanent ROOT access
For LOCKED evos, it will give temporary ROOT access
If you have problem unlocking, try grabbing a RUU file here and reflash your ROM... maybe factory reset wont hurt either...
it has run thru all the process with success, but when i try to open root explorer it show superuser force close???

Also the Same thing happened to me !!!!
Yup, not working here either.
It says it installs everything ok, but when I go to update the su binary, it force closes out. When I use TI backup, it says I don't have root access.
Hope this helps so that we can at least get temp root. I just want to remove the bloatware!
Thanks for the hard work in any event!
tried this on sensation xl and it worked, root access to some apps like root explorer but terminal says access denied. it seems to unmount the internal sd card which programs need to run and only a reboot remounts sdcard but obviously root is gone after reboot. hope one of the XL devs can use this to create a working solution for our XL

dont need to update the SU binary.. just run the scripts and they are good to go...
however, SYSTEM/APP are in locked partition of the bootloader.. you may need to unlock your bootloader first.. but you may remove some in the Data/app llike gmail and stuffs (i prefer Exchange email than using Gmail app)

If your bootloader is unlocked, then you may be able to reboot and still have root..

FULL ROOT if UNLOCKED BOOTLOADERS

Just tried on my HK Evo3D (HBoot 1.49.0012, completely stock, no HTC unlock) and it works. But it took me a few trials to get it working.
For those who have problems with the script (e.g., permission problems during the script) try:
(In the following steps, make sure ur evo3d is disconnected from ur pc when you reboot it. Just to make sure that it is clean.)
1) reboot your phone
2) run the unroot script
3) reboot once more
4) run the root script "Step 1.bat"
5) *** go into the "files" directory ***, and run the "Step 2.bat"
6) at this step you should see the superuser is installed (check the app drawer)
7) go to Settings to mount your sd card
I have managed to root it and run through a titanium backup successfully. Thanks for the great work!
Though temp root is gained, system is still mounted as read-only
tried these, neither one worked:
1) adb remount
"remount failed: Read-only file system"
2) su; busybox mount -o remount,rw /system
No messages, no errors. But still system is in ro mode:
# busybox mount -o remount,rw /system
busybox mount -o remount,rw /system
# mount | grep system
mount | grep system
/dev/block/mmcblk0p22 on /system type ext4 (ro,relatime,barrier=1,data=ordered)
3) su; fixit; busybox mount -o remount,rw /system
Same result.
Seems, after running "Step 1.bat", the /system is temporary mounted as "rw", (that's why the script could complete without warnings/errors). But after Step 2 finishes, /system is back to "ro" no matter what...
Any insights?

You may have previously attempted some other methods, therefore you need to clean the system first...
If your bootloader is LOCKED, you still can gain TEMPORARY ROOT access and run you Titanium Backup (restore settings, data apps).. however, the SYSTEM partition is still locked, which means, whatever changes you done to the SYSTEM partition (like restoring some SYSTEM apps) will be lost after reboot.
I got forceclose with the superuser.
I dont know why, but i guess the root process was finished

Thanks for your inputs. But my phone was completely stock and I have never tried other root methods before trying this one.
I observed that, /system actually get rw for a short time after the mount -o remount,rw command in step 1. But somehow it will get back to ro by itself. The time is unpredictable in a sense that sometimes step 1 script cannot finish successfully (cannot copy busybox, su to /system because it changes back to ro so quickly).
I know that the SYSTEM rw is just an overlay and all changes will be gone once rebooted. I am asking this because I just wonder if I could playaround and test something like changing fonts without s-off or HTC unlock.

[Q] How to ADB push?

I'm trying to push files to /system via ADB. However I'm having problems (getting permission errors). I am running Eclipse 2.0.2, so yes, my phone is rooted, I have su and busybox.
Phone is connected to PC and is set as "USB Mass Storage".
USB Debugging is ON
Here is my CMD log:
Code:
C:\android-sdk\tools>adb remount
remount failed: Operation not permitted
I tried to remount and it failed
Code:
C:\android-sdk\tools>adb push C:\myfile.apk /system
failed to copy 'C:\myfile.apk' to
'/system/myfile.apk': Read-only file system
I tried to push, and got a READ-ONLY FILE SYSTEM error (keep this in mind)
Code:
C:\android-sdk\tools>adb shell
$ adb push C:\myfile.apk /system
adb push C:\myfile.apk /system
adb: permission denied
I try to push inside of ADB shell. Nothing again...
Code:
$ su
su
# mount -o remount,rw /dev/block/mtdblock4 /system
mount -o remount,rw /dev/block/mtdblock4 /system
# exit
exit
I go into SU and attempt to remount the /system
Code:
$ adb push C:\myfile.apk /system
adb push C:\myfile.apk /system
adb: permission denied
$ exit
exit
I go back up to ADB shell and try to push again... same error as before
Code:
C:\android-sdk\tools>adb push C:\myfile.apk /system
failed to copy 'C:\myfile.apk' to '/system/myfile.apk': Permission denied
I go back to the main command line and try to push again. This time I get PERMISSION DENIED. This error is different than before.
Any help on the matter?
I've read about ro.secure needing to be set to 1, but I need to edit the boot.img in order to do this, correct? Does that require an unlocked bootloader? Is root ADB even possible on the DX2.
Thanks!
I am no expert (don't even know if i know enough to b called a newb) but maybe try a root explorer. I use es file explorer because it's free. In settings check root explorer and mount file system. I received similar errors and this solved my problem.

I'm familiar with root explorer, it's easy. I'm wanting to be able to use ADB though. Your post made me try something new though. I plugged my phone into my PC, then went into root explorer and mounted everything as RW. But, still was unable to push via ADB. Thanks for the reply though
So, how can I get ADB working?

Make sure there are no spaces in the file path to your android-sdk folder. Can't say if this is your issue but its worth a shot as it has always caused weird problems with android development since day one.

Ro.secure is in your local.prop on the root of your phone. As far as your issue you have to reset permissions in order to push to /system. I saw that you were trying to do that but with no success. I believe I know what will help but I will have to find it and repost.

Ok look at the command lines at the bottom of the op. You are going to use adb shell. Follow that almost exactly but adjust according to your directories. Should go into adb shell, gain su permissions, mount /system rw, push your apk, then don't worry about remounting as ro, just reboot. Pay close attention to spaces.

Took me a few days to be able to getting around to trying this, but it didn't work :/ I'm still getting all of the same errors. The /system just doesn't seem to want to mount as RW (even though it is possible when using root explorer).
As for ro.secure in my local.prop, I'm able to edit this but it resets on reboot because (from what I've read) this is a file generated by the kernel
Anyone else have ideas?

Moon shadow has a post in development to mount system rw
It's some type of script u run before adb or something
I don't know anything bout adb
But I do know he created it for this reason
Check it out
It's prolly got the info you need

Thanks for that! It's not quite what I'm aiming to eventually do, but did give me more insight on how the whole adb/shell/su systems work. From inside of su, I was able to mount the /system as RW, however I'm only able to do this from inside of SU. I want to be able to do this from the initial CMD so that I can ADB PUSH from my computer to the phone.
Here's my latest log:
Code:
C:\android-sdk>adb shell

So now the question is, how do I mount as R/W so I can use ADB push?
Wes
Maybe its because im tired but im confused as to why it wont let you push your files if you have remounted as rw. At that point it should be cake. You gained access to system by remounting it as rw successfully already.

Try:
Code:
adb devices
adb remount
adb push [filename] [destination]
adb reboot
the "adb remount" remounts the fs RW instead of the default RO.
I'm no expert in ADB, but I had run into the same issue as you and for me the fix was to go into ADB SHELL , then type SU to get SU access, then type exit twice to get out of shell completely. Then I tried pushing the APK and it worked fine with no read only errors.
This worked for me on my SGS2, could work for you ! Goodluck !
Come to IRC and I can help you with this. http://webchat.freenode.net Come to the #cm7dx2 channel. I'm usually there... Look for the nick(s) Moon|Work|(something), Moon|Home|(something), or MoonShadow-NM. If the (something) says Busy, I might not answer right away. If it says Away, I'm away from the keyboard and you won't receive a response until I return.
Ciao!
Any update
did you ever get this figured out? I'm having the same frustrations on mine. Mine won't install the 2.3.5 update due to it not recognizing the Quickoffice.apk and I'm trying to push the files manually, but I'm having no luck getting past the same you've posted here.

Do this
Sbf to 2.3.4
(or 2.3.3& take one ota To get to 2.3.4...however you want to do it..just be bone stock 2.3.4 )
Root your device.
BUT DO NOT USE ZERGRUSH TO ROOT
Use petes Motorola one click root method.
Then continue the process as normal from there on out.
Trust me in this. Zergrush root method is not playing nice with your /system partition, (if you notice during the root process it might say something like "making room in system,"= or "moving/deleting app to make room" something similar)
And when it does that, it's messing up how the update checks for untouched stock apps.
Let me know how it goes.
This solution has worked for COUNTLESS others so far, zergrush has always been the culprit when it comes to failing to find certain apk or system file that needs to be there for the update to install.

This won't work with Eclipse since it's not using 2nd init. I asked this question in the Eclipse forums and Nitro responded with the following:
Not without using 2nd init. All of that works due to being able to load its own init.rc which starts services and passes parameters, etc.. during boot time. It is possible to make a stock rom use 2nd init. CM9 will not even have root enabled by default. The only other way to push stuff is to enable root shell prior to pushing.

I know that CM7 allows using the adb remount, but that's because it's using 2nd init. I had also asked the question about why CM7 defaults to root shell when you adb shell into it and that's why he mentions how CM9 won't have root enabled by default.
The way I push to Eclipse is to run root explorer on my phone and mount the directory r/w. Then, I can use "adb push" to the phone.

I think I may have tried that in one of my iterations. Originally I had it rooted with One-Click and then I was having issues with the 2.3.5 OTA update (quickoffice.apk) and at this point I've SBF'ed and rooted it probably 5 times this week so far. Rooted with both One-click and zergRush at various times. Actually I think every time except this last time has been with one-click. So I don't think that has seemed to make a difference for me so far. I can try it again, but if there's any other advice to throw out in the mean time, I'll take it.
Alternatively, I may take the new phone (the first replacement they sent had 2.3.5 on it, but a bad menu key causing the phone to flip out), load Titanium Backup on it, backup all the system apps and restore them to my original phone. Worst case is I have to SBF it again. But that seems like a logical process since I will have two phones available.

Easy regain partial root with jellybean!

ok guys so i wanted to post this because ive been sitting here for two days trying to regain root on my prime after doing a factory reset to speed it up! It was pretty damn slow so i bit the bullet and its much faster now but unfortunately no root I tried to use the debugfs root method and it wasnt working multiple errors and still no root. Now a few things first i had used voodoo in the past to protect root, it sorta worked, voodoo stated my device had root but no program could actually get root. Also like i said the debugfs method was a no go and a few other options i tried. Im currently locked and rooted with full permissions. These are not my instructions but they solved my problem way too easily so i had to share. I found this over in the tf300 forums at this thread Nooktablets tf300 rooting thread i dont know if this will work if u have never rooted or never once backed up.. But i was having problems with errors in other methods so try it out and let me know how it works..
directions:
1) Download the unsure su from here and put it somewhere on your C Drive. It will be used in the following push step (Assuming windows) (This is a WIDE OPEN su without any controls). (sparky root i believe?)
https://www.dropbox.com/sh/jcpilpgoeta516e/tCB-Ep-3YQ
2) start a CMD window and logon to adb
3) su -
4) verify you have root:
id
uid=0(root) gid=0(root)........
If you don't you can try these instead of 'su':
"/system/su-backup" or "/system/su_backup"
5) remount system as RW:
mount -o remount,rw /dev/block/mmcblk0p1 /system
6) make a backup of current su just in case in adb
cat /system/bin/su > /system/bin/su1
7) open a new CMD window and push the su binary from step 1 to the sdcard using the path from where ever you put it.
adb push c:\<some path>\su /sdcard/
8) Then copy it to /system/bin from the adb session where you su'd.
cat /sdcard/su > /system/bin/su
9) Change permissions for SU
chmod 6755 /system/bin/su
10) download superuser (NOT SUPERSU) from play store if you do not have it already.
11) have superuser upgrade the su binary. It may fail to remount system as RO. Just rerun the update in superuser and it will work the 2nd time. You don't need to remount system as RO manually since superuser update of SU will do that for you.
12) congrats. your now rerooted.
13) remove the backup after you know your OKAY.
mount -o remount,rw /dev/block/mmcblk0p1 /system
rm /system/bin/su1
mount -o remount,ro /dev/block/mmcblk0p1 /system

This procedure worked for my TF201 with partial root after updating to 4.1.1. The only issue was step 11, the forced update of Superuser's su binary. The message was “Making sure new su works..." but the result after several minutes was still "Waiting....". Should I rerun the forced su update? Despite this Vodoo OTA Rootkeeper did restore root without problem and Root Checker says thumbs up.
At this point, is there anything to do like switching to SuperSU that would make the root more future-proof?
Thank You! I have been trying to regain root after jellybean ota on my Motorola Atrix HD for the last week and a half. Finally success . I cant thank you enough!
After I upgraded ota to jb. Su ceased to work entirely the binary would not update. and all root apps were no longer working. i did have a su-backup but was getting nowhere in my attempts to use the app. i was only able to invoke a root prompt. i looked all over the internet not just the xda forums. i tried mattigriffs root restore. i typed into a command prompt for several hours each day.. all i ever got was a root prompt in adb shell. no prompt on the phone emulator. this is the only page that has worked for me. i noticed right away that the code was written differently than any other that i tried. also the su used is different(it is described as wide open) any way because of this i felt that others who were /are in the same boat. no root. may be able to get root back. I hope that answers your question. have a great day! .
You should be able to switch to a different root app. Never used this method but I have switched from superuser to supersu. Install superuser and run the binary update. Should tell you your binary is out of date with the name of the binary for the other root app. Update and reboot, then go back to superuser and check the binary update again. If it says it's up to date, uninstall the old root app and move superuser to /system/app. Reboot and you're good to go!

i think i tried that. istalling and uninstalling and subdstituting su and supersu. was not updating no matter what. also my adb push was not working so i copy pasted the su with my laptop while in adb shell. also updated su binary while in shell. it was already a system app from my previous attempts. anyway im good now
any one get it to work with no root/first time root? my prime wouldnt update via ota once on ics so i had to use the sd card update method to update. and from then on i never rooted again i then updated to jb and until 2 days ago i wanted to reroot but noticed there was no root method for jb yet. voodo root keeper just has super user app installed and ./system supports root protection both checked.
I'm in the same situation as fcortes626, I had to upgrade via sdcard method, and voodoo root keeper didn't maintain the root. I can't find any su backup in my filesystem.
I wonder if we can downgrade using the sd card update then root and go on from there........?

[Q] 4.0.3 HTC Temp Root Question

Hello everybody,
i have gained root access to my phone via backup/restore method through adb where local.prop is stored in /data/. So when i log onto my phone with adb i have root access. I copied busybox, su and the superuser.apk to the right place and removed the local.prop file again. After a reboot I was hoping to remove some crapware off my phone but to my surprise the binaries i copied vanished from the filesystem. So the phone reverted the changes by itself. I did this process several times copying busybox and su to various places referred to by $PATH, but it´s everytime the same after i reboot. The files are gone.
After the first attempts failed i tried to make changes to my phone while logged in as root. I wanted to uninstall unnecessary packages with "pm uninstall" but that failed also. The command just responds "failed". Even when /system is mounted rw (it remounts itself to ro after a while though). I´ve also made changes to /init.rc but they are also gone after a reboot as other changes i´ve made. Basically i wasn´t able to accomplish anything with root access no matter what i did.
So what i want to know is how this black magic works andy why i cant do anything with root. I know how to achieve real root through htc dev and various other methods.
Thanks for reading!
