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.

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?

From a terminal write
adb root. (will give root)
adb remount. (will remount system as r/w)
adb shell cp /system/app/swype.apk /system/app/swype.apk.bak
Adb shell rm /system/app/swype.apk
This link is what i used to use to gain rw permissions

Alternatively from terminal on the phone type
su
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
Assuming your sys partition is mntblock3

Yes both methods installed the "Superuser Permission" 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
I have recently switched back to Project-V and adb does not seem to have root access. When I try the command "adb remount" I get the error: "remount failed: operation not permitted"
I am able to manually mount my system r/w with Root Explorer, but not with adb. Any ideas?
Check your permissions of root with superuser.
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........?

Hey guys,
I'm having a problem with ES file explorer. After several days I managed to root my HUawei U8800 Ideos X5 (Android 2.3.5) and obviously one of the next steps is installing CWMR. Unfortunately I'm failing here too. I tried to copy the recovery.img to the .cust_backup/image, but it keeps to say copy failed. Root access was given and I checked all four boxes in root settings. Someone in a german forum told me to update the binarys in SU, which failed too (it says sth like copy su to /system -> failed!). I'm not even sure ES FE would work if the binarys would be current.
Is there someone who can help me? Any ideas?
I already tried the app Mount /system (rw / ro). It didn't work with this too.
Thanks a lot.
no ideas?
You must have the /system folder mounted for read and write, default is read-only.
Different folders in the file structure could be located on different file systems, the easiest way to be sure that you have read and write access were you want to put files, imho, is by using root explorer.
If you are rooted and ES have root permissions then the problem is that the folder is non-writable. I don't know the app you tried to use to mount the /system as r/w but it's easy to do in root explorer or through adb shell with a little bit of *nix knowledge (su and mount -o remount,rw).
Should work from terminal emulator app as well.
C:\Users\...>adb push C:\recovery.img /.cust_backup/image/
failed to copy 'C:\recovery.img' to '/.cust_backup/image//recovery.img': Read-on
ly file system
before I typed
adb shell
$ su
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
Doesn't work. adb etc. is installed.
I'm really desperate about this now, I think something is really wrong with my system partiture or something like that. I consider formatting it, the problem I obviously have is that without CWMR I have no clue how to do that and how to flash an OS after it. Does someone have ideas about the whole issue? Interesting facts about my device: Often I'm not able to flash a stock ROM, it stops somewhere in the middle of the process. Rooting works often, but not always with SuperOneClick or zergrush. At the moment my superuser app says "root app_63" in a red font instead of "root root" in a green font, at least I have current binaries at the moment, but this doesn't work always as well. Seems like I am pretty alone with all these problems, that's why I want to format /system...
Please help me! Thanks
Give root explorer a try!
Sent from my OC ed mind.!
Why would you think that would work? ES File Explorer does basically the same...
Dont EVER try to format /system or u r gonna end up completely bricked. Just take your phone to a service centre and see what can be done. If you are under warranty, replace the mobile.
Hope i helped .

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!

Thanks for the reply. i use mount -o remount,rw /system as mount command to get read/write permission on /system. If there is something more to do please let me know. And if the behavior i ve seen is caused by the recovery.img is there something i can do about it?
