hello guys. i own a micro-max a90s running ICS. it worked fine but few days back it suddenly showed errors like acore stopped, calender stopped, etc no app works properly. i tried every possible solution i could fine but vain.. tried to factory restore from phone but it id ok no use ... tried to format cache and data partition from stock recovery but it just completes but nothing really happens. Then i tried to format using SP tools but it also completes but in vain.... i am no able to side-load apps...
Finally i figured out that my /data partition has been set as read only . i tried to remount it as read write but it doesn't work. Now i need to help to change my /data to read write. or any other solution that will work. thank in advance

As of yesterday, my CM7.1 phone won't boot - it gets stuck at the "rotating arrow" blue Android for ever. It's a Samsung Galaxy S II GT-9100.
I have been running CM 7.1.0 for several happy months now, and haven't tried to install or upgrade my ROM. The last action I took before this happened is that I made a full system backup (using CWM 5.0.2.6).
That backup is present on the internal memory. I can boot into recovery, mount drives and access devices using adb shell. So I do have an opportunity to fix what's broken, if I can work out what it is.
Given that the last thing I did was a backup, I checked to see if any of the partitions were full, but none are. (None is more than 42% full according to df; although strangely, df does not show any partition mounted on /.) I tried making another backup, watching carefully - that worked fine. I tried restoring the first backup - no improvement.
I've also tried wiping everything Recovery allows me to that's non data-destructive - cache, Dalvik cache etc. It hasn't helped.
How do I work out what's wrong? Is there a boot log file anywhere which might give me a clue as to what is wrong? I've searched for "*.log" but can't find anything obvious.
I don't want to do a factory wipe if I can avoid it, because obviously that will lose all my data. If I do a factory wipe and restore just the data partition, does that put me pretty much back where I was? If so, how do I restore just the data partition? The Restore option in CWM Recovery seems to do full backups only, and only from a particular directory.
The original CM and Google Apps zips are still on the internal SD (same versions as are currently not working). Would it be worth trying to reinstall those, without wiping? Or would that be data-destructive?
Any other ideas?
Thanks!

SOLVED - remove 0-byte data/system/profiles.xml
I tried doing a full factory reset from Recovery. This got the phone booting again, but without any of my data . Fortunately, ClockWorkMod has a "partial backup restore" function. I restored the data partition... and the phone stopped booting again.
So this is progress. I now had some idea where the problem lay. I finally found it using a laborious 5-minutes-per-cycle manual bisection technique. Delete half the stuff on the data partition, reboot, if it still fails, delete more, reboot... once you get it to boot, restore the data partition, narrow it down further. Once you find a top-level directory, repeat the process inside it.
The result: the existence of a single 0-byte file stopped my phone from booting entirely. The file was: data/system/profiles.xml.
I have no idea what that file does (there are only a few references online), how a 0-byte version of it got created, or why having it existent but empty breaks things but if it's not present everything works fine. I have no idea if anyone else will ever see this problem, or if they will ever find this forum post. But still, here's my Wisdom of the Ancients (google the phrase for the relevant XKCD comic).
This error is still not answered on the forums so im starting a new thread.
i get the error as the title.
sd card space is not the problem.
i tried formatting the sd card.
i have less than 50 apps installed.
wiped dalvik cache, and all other sorts people say on other posts.
(my phone is LG P936 so "fix permission" screws up the phone. all text disappears)
have latest cwm recovery.
and still get the error.
any answers please?
and please dont reply if you are going to write an opinion.
only answers please.
sorry for my rude behaviour but I'm sick and tired of reading posts full of opinions and "maybe"s.
Not sure if you ever got this fixed but I 'm suffering from the same error. I tried pretty much everything you tried (even fix permissions) and I have about 20GB free on my SD card so space shouldn't be an issue. I have not yet tried formatting the SD card since it has always worked and CWM is able to write to it because the following files are created:
- boot.img
- data.ext3.tar
- recovery.img
- system.ext3.tar
The files that are missing are (based on older backups):
- .android_secure.vfat.tar
- cache.ext3.tar (probably because I wiped it first?)
- nandroid.md5
I have attached the log from CWM in the hopes that someone can tell me what is wrong. The error occurs at the end of the progress bar of 'backing up /data'.
hey just use TWRP Recovery. It's way better than CWM. normal backup on cwm took me like an hour but twrp was never longer than 10minutes.
Today I have formatted the SD card and tried again, but as expected it did not change anything.

I guess I will give this a try. Can I just install it over CWM or can they run side by side?
different reciveries cannot be run side by side as they are installed on a different partition. so it will always be installed over your current one.

Well, I tried TWRP and it also fails at backing up my data partition. The log is a bit more clear though and it seems to get stuck on "/data/data/com.android.vending/cache/images" which is the last line before it gives an error. I checked the "images" folder and it seems empty but I cannot delete it. Tried ES File Explorer and Terminal Emulator but no way to get rid of it. The folder appears to be related to Google Play, so I cleared all data and cache from Google Play, even uninstalled the updates but there 's simply no way to get rid of it. I 'm not sure if this is the reason why the backup fails, but I CAN copy the folder and even rename it.
Pff looks like I 'm going to have to do a clean install after all .
Hello, I too have this problem and unfortunately TWRP is not available for my phone.
I used to be able to do CWM backups fine on my old phone, and they work great on my tablet. But they consistently fail at "/data" on my Galaxy Ace II x. Might it be because I'm using Link2SD? I don't see why that would cause a problem, but maybe it's having trouble with the symlinks?
Hmm. Seems the issue was that, despite having only 1.28 GB total available storage space on stock, the backups wanted more than 4 GB. Cleared some room on my microSD card and suddenly backups worked fine! Of course, shortly after I installed CyanogenMod, which has much smaller backups...

I forgot to report back here but the only way I found to fix the problem was by doing a clean install. After that, I was able to backup my data partition again. I then restored my apps ' data with TB and was unable to backup the data partition again. I 'm guessing one of my apps had corrupt data, but never got to find out which one it was.
maybe your partition not match with recovery, like something wrong vold.fstab
Just in case anyone still wants to know how to fix this, I managed to solve it by running these commands:
1. run adb shell in recovery.
2. unmount data partition (umount /dev/block/mmcblk0p26). -> this one failed so I skipped it
3. run e2fsck /dev/block/mmcblk0p26
See http://forum.xda-developers.com/showpost.php?p=48659092&postcount=868 for original post.
I got a few HTREE errors and a bunch of duplicate names which I renamed when prompted. Booted the phone and rebooted into TWRP and now I am able to backup my data partition again. :good:
EDIT: Problem reappeared so I tried the above commands again but it said that the filesystem was clean. Ran 'e2fsck -f /dev/block/mmcblk0p26' instead and had to fix a bunch of HTREE errors from Facebook again and duplicate names from Xprivacy but now I 'm able to backup my data partition again.
Dude just selest the backup format as both zip and tar filea
Allo gents here's the issue as quick as I can explain it:
- had back ups of everything
- installed Slim Bean i9300-4.2.2.build.6-OFFICIAL. Failed to format the right folders properly.
- wiped Data, Cache, Dalvik
- found that CWM couldn't mount /sdcard, /efs, or /data
- as a result, no backup, and god knows what is destroyed.
- currently downloading stock ROM hoping that will help (6 hour left on download though...)
- installed TWRP hoping for some better options. No avail.
I'm stuck at Samsung loading screen. TWRP is accessible but no OS. I need options, anyone have ideas?
Thanks for your time.

Have you backed up your EFS folder ??
If so restore no backup take it to a service centre .

Hi everyone
I'm facing a very annoying problem. my Atrix show and explain the problem to me even though I telephonist is all programmatically, they said I need to format but I think I have hardware.
When I turn off my phone every December 6 turns. For example, when I delete one to two applications, photograph shoot, when I reboot the phone by the programs have come back, if my photography is gone, WhatsApp My speech is going back to December 6.Connect the phone to the PC in the same way music, rom, etc. when I threw the zip file .. usb disconnect the look of the phone seems to have deleted files, seems to throw more precisely, I cant go to the factory settings, I cant format sd card.Fastboot mode operations such as hard reset formats'm doing. When he opened successfully but says does not change anything from December 6 phone again Cwm in the mount process data, cache, system, Preinstall, gives an error when formatting. Original GB Stock ROM flashing with RSD, but the phone while flashing process is going repositionable 6 december. Most application itself off, the process terminates, etc.. In short, I can not do any operation with built-in storage, screwing with my head.
Restore backup operation did with cm7 but it did not work .. I'm going crazy I stayed at this rate

motorola turkey on the forum topic I said like a friend;
data partition in a way locked there is no problem, linux to interfere with necessary, the easiest services to take, If it fails either of these issues knows linux expert to find, or the phone to open the internal mmc card, remove the atrix in accordance with partitioned, separating reformat back will wear a hardware specialist you need to find. Or one of them will make an application in android professional applications because newly started dating, they needed to find an application that partition control.

My english is not good.. When you translate text in many places i used google translate
I hope you can help me and understand. :silly:
Greetings from Turkey !
That was hard to understand, being a non-native english speaker
Please, after recovery fails to write /data, go to main menu-> advance-> show log. There will be the cause of the error.
Hit the damn thanks button instead!

Hi,
I'm new around, hope this is the right forum...
I have a galaxy s1 (i1900) which I flashed with a new ROM (2.3.6) in the past and then installed 4.2.2 from a zip, and it worked fine for a few months.
Having the same ROM file I used before, I tried to get it back to 2.3.6, as the 4.2.2 didn't work quite well, causing some problems when trying to make phone calls / receive calls.
After flashing the 2.3.6 again, the phone kept rebooting itself. Having read a few different guides online I tried all options - wipe data, wipe cache, wipe dalvik cache... then did some dramatic things like formatting /system, /cache /sdcard... I know it's not a very smart things to do when you don't know what you're doing, but I guess I felt I have nothing to lose at this point...
I also tried to reinstall 4.2.2 again and it only rebooted to the recovery mode whenever turning it on.
When mounting to USB I see no files in the device at all, only a folder called 'clockworkmod' with file called '.recovery_version' inside, and 2 empty folders named 'external_sd' and 'LOST.DIR'. It also shows it has 13.2GB free out of 13.2GB, which is weird, because the os doesn't occupy any of the capacity.
How do I save this poor device?
Many thanks in advance for your kind help!
