[Q] Root help - "Read only file system" - Android Q&A, Help & Troubleshooting

Hi, any help with this one? I get as far as being able to push su and busy box but get "failed, read file system only" or "directory doesn't exist" Thanks in advance!
model PMID700
Android version 2.3.1
kernel version 2.6.32.27
build number 20110918.170336
Firmware version 2.2

I also have this tablet. The issue is the file system is cramfs which is read only so we can't move files to any /system folder. This is where every current one click root tool is failing.
On the positive side it appears we have shell root.
This is the output from doomlord's v3 root script:
Code:
...
--- copying busybox to /system/xbin/
/system/xbin/busybox: cannot open for write: Read-only file system
--- correcting ownership
Unable to chmod /system/xbin/busybox: No such file or directory
--- correcting permissions

--- installing busybox

link failed File exists
--- pushing Superuser app
failed to copy 'files\Superuser.apk' to '/system/app/./Superuser.apk': Read-only file system
--- cleaning
--- rebooting
ALL DONE!!!
Is there anyone out there that has converted a cramfs image to ext3 (or possibly something else, not sure what this supports yet)?

i got cat /proc/mounts to work in terminal emulator once and i did notice some others partitions were marked ext3 so hopefully a conversion would be possible i just don't know how and i cant seem to get the mounts again
*edit* cat /proc/mounts works in terminal emulator everytime
attached the important part of the output

Cool that's the same thing I'm seeing.
Code:
/dev/block/mtdblock4 /system cramfs ro,relatime 0 0
/dev/block/mtdblock7 /data ext3 rw,nosuid,nodev,noatime,nodiratime,errors=continue,data=ordered 0 0
/dev/block/mtdblock6 /cache ext3 rw,nosuid,nodev,noatime,nodiratime,errors=continue,data=ordered 0 0
I suppose its a little ambitious for me to try to go directly to ext3 so what i think i will try to do is to try to download the system image from the phone and then modify it with the proper files (from doomlord's oneclick v3) so it can be rooted.
I will update this thread with my progress.

Returned it...I'm all for tinkering, but not willing to go that deep good luck!

Hi just tryit but no luck i get this
failed to get shell root
thanks
Can anyboddy help me please
I'm having this same issue, none of the usual methods have been working.
try running:
adb remount
and then your root script.
what it does is it remounts the system partition r/w instead of read-only, so you can chmod and such

Check your phones development thread, there are separate threads for each version of the SGSII make sure you have the correct thread for your phone.

zergRush is not able to root ICS ROMs.
Do you now which one i can use to root my device but i don't want the yellow triangle on the boot up
Thanks
Yes, I do. You can too by doing a little looking.
Find a matching (or closest match) CFRoot kernel (assuming you have an I9100/T), flash it. Done. Root + CWM. Not rocket surgery.
Unless you're having a whole heap of problems you haven't told us about I.E "I have the same issue as bartoloandre98...I am on 4.0.3" is vague as you know what. Bit hard to help you without details
P.S - Zergrush won't work with 4.0.3
Edit - Oinky is right. This stuff has been done to death on here.
Oh well
Thanks for the update and your kind help
Thanks
Just downloaded Odin. Open it via a pc and flash a kernel like siyah which contains CWM. Make sure its tar format and open this in pda in Odin then your flashed.

I rooted my Mango once... and can't do it now o.O

OK, here's what I've done. I downgraded and rooted my SK17 several hours ago, and then removed some bloatware. everything went great, but then I decided I want to replace stock camera app with this one. as I didn't know how to do it, I thought "hey, why don't just delete the SemcCameraUI.apk from system/app and replace it with downloaded one"? so I did it, but it still didn't want to work. so I tried to reboot the phone. the app still wasn't working [by then I guessed it's not the way it's done], and then Root Explorer decided that it doesn't want to work with such a stupid human and told me that it can't delete the apk nor change the permissions because it's a read-only file. and the SuperUser app was force-closing.
so I flashed the phone with .58 again, I learnt that I lost the root, so I tried rooting it again, and then I got the message from the zergRush script:
failed to copy 'files\SuperUser.apk' to 'system/app/./SuperUser.apk': Read-only file system
Click to expand...
Click to collapse
any suggestion what should I do to root it again?
note: every time I flashed .ftf file, I was unchecking "wipe data", "wipe cache" and "wipe apps log".

er, yeah. that's how I rooted. I did it once, and then, as I said in post #1, lost it.

There's your fault.
As I had suspected it..
The anti-virus removes the ZergRush file even from the .zip or .rar file..
Disable anti-virus, download the rootingkit files again and the unpack and root your phone..
NOTE: While rooting, using flashtool, flashing kernel, please disable anti-virus temporarily.
And also while rooting your phone close flashtool if it's open.
all done, thanks! turns out I'm too dumb to remember that antivirus can peek inside zipped files.
btw, can anyone hint me how to replace the camera app with the one I was trying to?

NP
And flash the MDPI-GB-CamExtreme.zip file using CWM..
It's only for stock ROM I guess.
And don't forget to backup first using CWM.
thanks once again! thread can be locked now.

[Q] /system/xbin Read only when rooting Android 2.3.6

Hi!
Question related to Samsng Galaxy Mini S5570.
After been using link2sd without problem, I restore the phone for cleaning propurse and I had the bad idea of update the fimware with Kies, It stop at 80% and after two hours, desesperate I disconnect the cable. Good point of that I could do an emergency recovery with Kies.
The problem now is when I try to root, I get this error log with 'Easy rooting toolkit' (and many others):
Note: I have tried also with the same Universal Gingerbread that worked with other Mini 2.3.6 like a charm.

[QUESTION] Rooting a read-only device.

Hello Guys!
This is my first post on the forum, I will try to make myself as clear as possible. I have got a LG Optimus L5 (known as Swift L5), which I am trying to root. But there is a problem. I have been doing a bit of research, and I have found out that the Optiums L series are read only (the internal storage). And because they are read-only, I cant push the files onto the device, in other words I cant root the device! This is really freaking me out a bit. I hope You guys can help me solve my problem. Best regards
Please help guys
Again the problem was not looking for specific device forum.
However, here's your answer

Hi!
Thanks for replying to my thread. I have already followed that tutorial, and all I get is a message: failed to copy blablabla device is read-only.

You aren't understanding me. I didn't see ANYTHING in guide that was to be pushed in any partition that returns with read only error.
I was asking that what you were trying to push when you got that error. I know that you're trying to root. Tell me what I need to know to solve your problem
I suggest you to read the guide again thoroughly and then tell me WHERE you are getting error.
I get the error, when I start root.bat:
