[Answered] File System read-only after permroot S-OFF

So I just rooted a Glacier out of the box using VISIONary and gfree. Did everything exactly as was supposed to: temprooted, ran gfree, permrooted with "Set system r/w after root" checked, flashed engineering bootloader. Still running stock ROM.
Whenever I try to use adb remount, it fails saying "Operation not permitted." I want to use adb push to write to the file system, but I can't do that without the remount command.
I've tried using terminal emulator to copy a file from the sd card and failed:
Code:
$ su
# cd /sdcard
# cp -f hosts /system/etc
cp: cannot create '/system/etc/hosts':File exists
I've also tried outright deleting a file and failed:
Code:
# cd /system/etc
# rm hosts
rm failed for hosts, Read-only file system
I'm stupefied.

To be sure you could download a root explorer and see if you can mount R/W

Is there a free application that does this?
Unfortunately, I won't have access to it for the next few days (someone else's phone, and he's going out of town).

the stock rom doesn't except the remount command.
I believe that astro has the remount ability in it. You might want to consider flashing a custom rom though, even if its one of the stock based ones.

I see, thanks very much for the explanation. Is that also why the terminal commands didn't work? Does the stock ROM not allow r/w permissions even if you have superuser permission?
Since it's not my phone, I didn't flash a ROM, only ClockworkMod recovery 3.0.0.6. Next time I see him I'll ask whether he wants to do any firmware changes or not.

That's correct... I think. all I know is that the stock Rom doesn't usually play well with root lol so yes flash a custom rom

You can make the stock rom rw, but its a pain and I dont really remember the command. Its something like
Code:
mount -o,rw remount /dev/block/mmcblk0p25 /system
That may br right, but if not it wont do any damage. just give you a syntax error.

Ah yes, I remember using that once before. I've since forgotten it since I never use it with my own phone. Alrighty, I'll mark this as answered.

Cant acquire root privileges

Im having trouble with root privileges, I rooted my phone for the first time the ohter day using the user guild for noobs and had a froend help who knew what he was doing. Everything went well and the phones running a treat. Only issue I got is I dont have root privileges and I dont know why? Any suggestions?
Not sure what info you may require.

Explain how you rooted and your software (os) version so we can help you better.

So you flashed the CF rooted kernel?
Try putting your phone in debug mode and open a shell to it using adb. Once inside check to see if the su binary is in /system/xbin.
ie:
Code:
adb shell
$ ls -l /system/xbin/su
if you see something like this, you're golden:
Code:
-rwsr-sr-x root root 26264 2011-08-16 15:49 su
(also notice the permissions, it needs to be setuid, although I would guess if it is there it is unlikely it is not setuid)
if you see this, something's wrong:
Code:
/system/xbin/su: No such file or directory
if you have su, have you installed the superuser app from the market?
if not, you have to figure out why..for example, do you have space on your /system filesystem?
Code:
$ df /system
Filesystem Size Used Free Blksize
/system 275M 256M 19M 4096

[Q] Rooting a rooted Verizon Droid 2 to Gingerbread 4.5.601.A955.Verizon.en.

Does GingerBreak work with this version of Gingerbread 4.5.601.A955.Verizon.en.us? My phone is currently rooted with Z4Root 1.3. Is there an easy way of doing this?
Sam

Use the d3 root method. Works fine.
CM7GB-601

The D3 one click didnt work for me. It tries to reboot and the phone sits at the "Battery OK OK to Program Transfer Mode: USB" mode.
I was rooted before the update. I never used ROMS or anything just rooted for wireless tether and T backup. Not sure how to proceed but Im pretty happy with the update, fixed a bunch of issues for me.
Anyone else not able to root after the ginger ota?

I have the phone in PC Mode (instead of Mass Storage.) I don't know if that makes a difference.
The D3 Method worked great for me and my wife's phone.

Hi everyone,
I have the same question as CSSZiegler, but want to expand on it a little bit...
I have a Droid 2 that was rooted with Z4Root 1.3 several months ago. I also have SetCPU, SuperUser and Titanium Backup. No custom ROMs installed. Big Red just pushed down GB, and of course, I've lost root access. I'd like to regain root again without losing any contacts, Handcent messages, etc. I've read on several forums that the D2 can be rooted just like the D3 with a simple "one-click" operation referenced by quarky42 earlier.
Any opinions or experience with this? I greatly appreciate any and all assistance!

update
My phone downloads the update, I click install now... it reboots and starts the install, then about 35% of the way through, it turns to a triangle with ! Inside. Phone reboots and displays message software update failed. Anyone know where to find a logfile or have any suggestions?
Droid2 android 2.2.. rooted. No custom rom.

Did you fully SBF to stock using RSDLite?
Also http://forum.xda-developers.com/showthread.php?t=1246673 has a flashable version.

I will as soon as I get a computer again, thanks for the link. Unfortunately my mobo died yesterday. So I was hoping for an alternative solution. It would also be nice to keep all my texts.. I'll google that one.
So any ideas on the logs or an alternative solution?

Ok... I have also used Z4root. I got the update, it failed. I unrooted with Z4root. Re-downloaded the update, it failed.

I had the same problem, and I think it is is because we already had Superuser installed. To remove it, from the directory where you downloaded the one click root, open the command window, then type adb shell
when you hit enter, the next line should end with a #
if it's $, run the one click again, then start this over
once you have the # prompt, type
mount -oremount,rw /dev/block/system /system
rm /system/bin/su
rm /system/xbin/su
hitting enter after each line.
After doing this, run the one click, and it should be fine. Worked great for me.

I'm having the same problem as the original poster... Installed gingerbread with z4root... phone was already rooted.. Now I have superuser and can't get rid of it.. .Tried unrooting through z4 and it doesn't work... Tried gingerbreak and the one click root through windows... Neither of those worked...
I either want to root through gingerbread or just get rid of the superuser.
when I type adb shell in command prompt (in windows 7) it says adb is not recognized as an internal or external command, operable program or batch file.
Any ideas? Thanks.

I would SBF back to Froyo with RSDLite and install the OTA GB from phone info updates. After that use the D3 one click root method and you're golden.

That error is usually because your trying to run the program from the wrong directory. Make sure your command line is started from the folder that adb.exe is located in. You can do this by Shift and right mouse button and “open command window here”.

I searched the phone's sd card.. I couldn't find it... do you know where adb.exe is located?

The fact that he said to hold shift and the right mouse button should tell you he's talking about a folder on your computer and not on your SD card.

Finally got it to work... now.. I used motorola one click root.exe where you use the exe on the computer. Just out of curiosity, is there a one click method to unroot? Thanks!

Titanium backup can't get root permissions

I have the 16 gig Nexus 7 which I have rooted but having tried to backup my ROM I find I am unable to reboot into Recovery to perform a ROM backup. I also cannot flash to the latest version of Clockworkmod, I have version 6.1.0 when I am told that 6.2.3 is available. When I try to flash the download reaches 100% and says flashing before telling me an error has occurred. Also Titanium backup can't get root. Is it possible I am not fully rooted and is there a way to check? Thanks in advance.

There is an app called "Root Checker" ... Do you have SuperUser installed and does it open?

Yes I have superuser installed and it does open OK and does list some apps as having root permissions. I will try the checking root app and thanks.

Have you tried wugfresh's root toolkit? It's easy to use. I've rooted, and reset and rerooted several Nexus 7s with it and never had a problem.

Why do you have 2 SU apps installed? That's probably what is messing you up.
Remove super user and re flash supersu from fastboot. The supersu flash will make it work.

Hi mate
Seem like you lost root ...yes re root again , it should solve your problem

Up.. any ideas pls?

Any ideas on how to solve this? I'm having the same problem on my Galaxy Note 2 (SPH-L900) running 4.4.2. Re-rooting with Odin and the latest CF file doesn't help; it still reports the same problem. I've tried un/reinstalling SuperSU, but that doesn't make any difference, either. Any help would be wonderful.

I'm already running a custom Community ROM that already has all the Knox stuff removed. It came rooted, and worked fine for several months, until it magically lost root access a month ago.
I *REALLY* don't want to wipe the phone and flash a new ROM, because my lack of root access means I haven't gotten a complete backup in over a month.
