Data corruption / can't backup

Fat Free Froyo, sys on NAND, data on EXT2 partition
getting a lot of corruption issues, e.g. woke this morning to find it locked up, so had to reset, lost two apps, google account settings and my wallpaper
will try moving the dalvik cache as per this thread http://forum.xda-developers.com/showthread.php?t=853852 but I don't know how to open a terminal!
I thought I could solve this by regularly backing up and then restoring whenever I am forced to reboot but when i try i get a ton of errors (supposefly mke2fs related) and it says it couldnt copy.
so basically I'm shafted, help!

You need to clean data or connect to a linux machine, and try to check the disk

My ubuntu partition is not booting on my laptop since i swapped the wifi card, lol, today is not my day!
Are you saying the failure to backup is because the data partition itself is bad?

Seems to be fine now. I had a ton of corruption after a crash last night. rebooted a couple of times, clearing dalvik along the way and then on the off-chance tried to restore /data and it came back. Seems like it WAS backing up and only a handful of files were throwing errors.
Got myself a terminal emulator and ran mount -o remount /data, shutdown, cleared dalvik then did a new backup and this time it ran without complaints.
Hopefully now if i get any crashes and bad things happen I can just restore, as I have all my email/apps/accounts set up just right

Indeed, have been keeping a keen eye on that thread and spotted the recent excitement, thanks

[Q] SGH-T989 frozen in time, advice requested, any ideas?

Hello, everybody. I have a T-Mo SGS2 SGH-T989 that's frustrating me, and I'm hoping one of you might understand what's happening and how to fix it. Its software seems to be frozen in time. Every time I reboot it, no matter what I've done to it, it opens on the homescreen I had in place as of last Thursday (6 September). As soon as it boots it downloads updates for every app that's had an update come out since then. Any apps I have tried to install since then give me a "could not be downloaded due to an error. (492)" message, and any already-installed apps I delete magically reappear unchanged as soon as I reboot. Not only that, but all the app cache data is frozen in time, too; Poweramp opens with the player cued to the middle of a track I had last listened to over Bluetooth in my car last Thursday, the Kindle app opens to a page within a book I had read last Thursday, etc. I can't make any permanent changes to my phone for no obviously apparent reason, though it's for the most part functional. To top it all off, though, after being powered on for a few hours, apps start randomly force closing until I reboot it again! I've been running essentially the same software environment on it for a couple of months, and up until last Thursday it was rock-solid reliable. I'm not a complete n00b, but I don't have nearly as much time as I'd like to devote to progressing beyond rank amateur status, and having my phone not completely functional is bugging the spit out of me. I've been trawling this and other forums as much as I can since then, and I can't make head or tail of this problem. Anybody have any ideas?
I've already tried wiping the cache and dalvik cache, I've tried restoring a backup from cwm, I've tried doing a factory reset and data wipe, I've tried darkside super wiping it, I've tried flashing new recoveries, I've tried to update the firmware through Kies, I've tried to flash it back to stock with ODIN, and I even downloaded the Android SDK so I could open an adb shell over USB and chmod all the file permissions to read/write! I keep encountering error messages in cwm and adb saying error mounting /sdcard, error mounting /sd_ext, error mounting sdcard/android.secure, etc. What really blows my mind is that everything seems to be working just fine in ODIN while I'm flashing it - until the phone reboots and shows me exactly the same environment it had before I flashed it. I had avast! Anti-Theft installed, and I disabled its device administrator privileges and uninstalled it before I made any of these attempts to fix it, but it keeps reappearing too. I'm at a loss.

This sounds like an Android virus... Did you download anything "suspicious" recently?

Yeah what he said.. You could always try a virus scan, however I have heard they aren't that reliable.. Easiest fix would be get a warranty replacement and be done with it.

Oh, dear.
I wouldn't have thought I had downloaded anything especially sketchy. I won't install an app unless it's got a lot of positive reviews, but I suppose that's no guarantee of absence of malware. The trouble with sending it in for warranty service is, I've voided my warranty by rooting it and installing a custom ROM, and I can't flash it back to stock.

If you already have a back up try this out. Format system, Format data, Format cache. Wipe cache partition, Wipe dalvik, Wipe data/Factory Reset. Do all these twice not once but twice then reinstall backup rom and reboot. See if this fixes the problem.

Creating a backup was the first thing I did after I rooted it, so I did what you suggested. The first four steps went well enough:
Reboot to recovery ---> mounts and storage ---> format /system ---> Yes - Format ---> Done. (x2)
mounts and storage ---> format /data ---> Yes - Format ---> Done. (x2)
mounts and storage ---> format /cache ---> Yes - Format ---> Done. (x2)
wipe cache partition ---> Yes - Wipe Cache ---> --Wiping cache... Formatting /cache... Cache wipe complete. (x2)
When I went to wipe dalvik, I got this error the first time:
advanced ---> Wipe Dalvik Cache ---> E:unknown volume for path [/sd-ext]
So I tried it again, and it seemed to work:
Wipe Dalvik Cache ---> Dalvik Cache wiped.
Just to be sure, I tried it a third time and got the error again:
advanced ---> Wipe Dalvik Cache ---> E:unknown volume for path [/sd-ext]
After several more tries, it seems to be alternating back and forth between telling me it works and giving me an error message, so I moved on:
wipe data/factory reset ---> Yes -- delete all user data --->
It seemed to partially work, but also gave me an error:
-- Wiping data...
Formatting /data...
Formatting /cache...
Formatting /sd-ext...
Formatting /sdcard/.android.secure...
Error mounting /sdcard/.android.secure!
Skipping format...
Data wipe complete.
I tried it again three more times and got the same results, error mounting /sdcard/.android.secure. Moving on, I tried to restore a backup:
- backup and restore ---> restore ---> E:Can't mount /sdcard (x4)
The thought occurred that it might be trying to access an external SD card rather than internal storage, so I re-installed the one I had removed prior to mucking about trying to wipe things and tried again:
- backup and restore ---> restore ---> Couldn't open directory. No files found.
This was new, so I went back to the wipe data/factory reset step:
wipe data/factory reset ---> Yes -- delete all user data --->
This time it seemed to work without any errors:
-- Wiping data...
Formatting /data...
Formatting /cache...
Formatting /sd-ext...
Formatting /sdcard/.android.secure...
Data wipe complete. (x2)
Since that seemed to work, I repeated all steps from the beginning and moved on to the restore step:
- backup and restore ---> restore ---> Couldn't open directory. No files found. (x2)
I tried the restore from internal sdcard option:
- backup and restore ---> restore from internal sdcard ---> Couldn't open directory. No files found. (x2)
I then tried the "- advanced restore" and "- advanced restore from internal sdcard" but with the same results ---> Couldn't open directory. No files found. (x2)
Then I rebooted it:
- reboot system now --->
And yet again, it behaves as though it's been powered down since Thursday before last.

Q TWRP Cannot wipe data/factory reset due to multiple lost+found folders

Using TWRP 2.6.3.0, I'm unable to wipe data. Every time I try, I get
"wiping data without wiping /data/media
E: error opening '/data/lost+found'
done."
I excluded the nonessential bits, if anyone wants a full log (something something partition details), I can make one.
I using ES File Explorer with root explorer on, I checked out /data and found two lost+found folders, which I think is causing my issue. I've tried deleting just one, but a second one is automatically generated. If I delete them both, then they're automatically recreated as well. If I delete them both and then remake one immediately after, another one will be remade.
I also checked the rest of the /data folder, and I did not find any lost+found files, so I'm pretty sure it's just the folders messing things up
I checked this thread, but I didn't find anything useful
http://forum.xda-developers.com/showthread.php?p=39497772
I ended up here after I accidentally wiped my internal storage with TWRP. I went from a 4.3 AOSP rom to 4.1.2 stock (HD RLS16). I wiped the 4.3 rom, but I think I accidentally wiped internal storage then as well, or maybe something was messed up with TWRP because the storage folder for 4.3 isn't in data/media (or at least not for the rom I was using). After that I used hyperdrive, which was super buggy with Gapps and didn't work at all. After adding an account, everything kept force closing, and things were extremely slow and took minutes to open, even after removing the account and wiping cache+dalvik.
I thought it had to do with the rom, so I went and wiped stuff, then went to CM 10.1.3 stable, but that didn't boot at all, so I tried wiping again and going to liquidsmooth 2.9, which is where my problems started again. I attempted to wipe again and go back to cm10.1.3. The wipe failed, but cm10.1.3 worked.
any ideas on how I can fix this? I was unable to find help on google.

Anytime you get that error format data (the one where you type yes) the folder gets corrupted and a format fixes it.

Im getting the same E:Error opening '/data/lost+found' im my twrp 2.6.3.1 after flashing Official CM11 nightly dec 12.
So now my recovery is very messed up, i cant properly wipe or restore nandroid with ease anymore, did you by any chance find a solution to fixing this issue?

This has happened to me twice and the only solution i have found was to wipe internal storage. unfortunately i wasnt able to backup my internal storage before wiping so eveything i had on my phone was erased. Everything in your external is safe you dont have to worry but if you had important files or anything that you wouldnt erase on your internal storage then that is very unfortunate.
As for me, i now backup everything maybe like once a month or so, just in case something like this happens again.

Its happened to me also and I could not resolve it without the wipe, that was the only viable solution that worked for me.

Although if you're using twrp I just found out you can still save some of your precious files.
How? Simple
You can go into recovery and into the file manager. I think it's in settings or advanced I'm not sure. But I know that is built into twrp. So then just go into your internal storage and select the files and move them to the external storage.
If it's your first time using the file manager then you'll have to get used to it because it's not 100% noob friendly
And remember the bigger the file the longer it'll take to move so just be patient.

Use AromaFM!
search bar will serve you..

Thank you very much, saved my life today!

Can i get some help please. I cant format data via TWRP, it says "E: unable to wipe data, unknow fle system, auto, unable to format to remove encryption". I did not put any encryption. What to do?

Have you tried using different versions of TWRP to wipe?

Solved: Play Store app causing a lot of issues. Factory Reset failed.

Update: Using Smart Switch (Kies), I was able to flash the Stock rom. By using the software, I didnt have to know what version to download or where to download. It flashed everything on its own. Just ensure that the cable you are using is proper ( i had a loose cable which was causing a lot of disconnects.
Hi All,
I'm on this abominable 4.3 version (T889UVUCOH4).
I see that after some partial update from Play Store for some games and stuff, the Play Store app stopped working altogether and is frequently showing the message "Unfortunately, Google Play Store has stopped" (pic1.png)
Tried a reboot, cache wipe, dalvik wipe before the dreaded factory reset. At this point I realised its either the factory reset or my phone getting drained to to constant messages from stoppage of the Play Store app.
I backed up all that I needed and decided to get rid of this completely by doing a Factory reset. To my sheer disbelief, factory reset is failing. I am using CWM recovery and Note 2 is rooted.
Code:
ClockworkMod Recovery v6.0.4.3
-- Wiping data...
Formatting /data...
Error mounting /data!
Skipping format...
Formatting /cache...
Formatting /sd-ext...
Formatting /sdcard/.android_secuure...
E:unknown volume "/sdcard/.android_secure"
Data wipe complete...
Rebooting
After this the phone boots up normally and goes on to throw up those "app stopped" messages.
If I do the Factory reset from Settings->Accounts->Backup and Reset -> Factory data reset -> Reset device then the following set of logs appear during the reset
Code:
ClockworkMod Recovery v6.0.4.3
E: Invalid command argument
Formatting /data...
E:format_volume: make_extf4fs failed on /dev/block/mmcblk0pl17
Formatting /cache...
Data wipe failed.
If anyone can guide me to either install a Custom rom at this stage or simply recover to stock rom, I would really appreciate your help.
I feel some guidance at this stage for me would be good as I have flashed roms and tinked a wee little bit performing Rooting and using Rooted apps and SU (maybe its useful or maybe not)
So please help me !

I would try using TWRP Recovery instead of CWM to wipe the device.
http://forum.xda-developers.com/showthread.php?t=1966105
If that fails then get a stock ROM you can flash through Odin (this will wipe internal memory)

I was able to flash the stock rom using Kies (Smart Switch).
I still cannot imagine why that error happened when I was doing partial App update.
Marking it as solved. If you have any concerns, please PM me.

Encryption Unsuccessful, data and system partition can't be mounted

I've been running Cyanide L for a while and today I see a message that says "Encryption Unsuccessful" and when I tried to reset, TWRP threw errors about how it couldn't mount the specified folder. Anyone know of any way to fix this?

I'm not sure if you found a solution but I would flash back to stock and start over. Flashing stock will probably require a complete factory wipe which means you'll lose your data.
