[TPT] CM10 Cannot wipe cache

Hi everyone, I recently rooted my 16GB WE TPT and installed cm10 v.0.8.1 and I love the performance and everything, if only there were no reboots. After reading in this forum I wanted to try to reinstall things from scratch wiping everything. For some reason I don't seem to be able to to anything with the data that is on my TPT. Neither can I do a factory reset from settings nor can I wipe data from Recovery. It doesn't display an error but it just doesn't delete anything. Then I tried to restore my backup from my original rom but this doesn't work either: it says error while restoring data (after recovery and system).
Can anyone help me? Could I have accidentally locked the data or anything?
Btw, Google Play has stopped working after my last try to restore stock and then install cm10 again.

In cwm you find under advanced a setting called "fix permissions". Try that

Hi, i had big problems with my Data-Partition. The Partition was read-only. No wipe with CWM was possible. Is that the same problem what you have? Do you have an logcat? Any error-messages?
Wiping was only possible with adb...

When it is the same problem, it exist an solution...

I don't have the same error messages you have/had, but I could image that my data partition is also read only since I can neither delete or install anything. What did you do to get rid of that problem?

The solution was to completely format the data permission. This can't be done in CWM directly because CWM tries to keep the folder /data/media, which is your internal sd-card and only deletes the other files (That's obviously not formating). In the link you can find a zip files that you can "flash" in CWM, it will format the data partition and does nothing else. After using it you should also manually wipe the cache using CWM.
Like i said, this will include your internal sdcard! Make backups first if you have important data stored on it!

I need to clear it - if I do "wipe data/factory reset" in stock ICS recovery menu - will it cause deleting ROM (and reboot will make brick) OR just will get it back to clean factory ROM?
I found few threads here about "wipe data"-thing, but it seems to me, that every version of Android / custom ROM / recovery type could behave different.

[Q] A200 data wipe failure -- no longer

Hi all,
I tried to update the custom ROM on my A200, but in the process, the data wipe failed.
What I did exactly, is use ROM Manager to load the latest JellyBean CM ROM for A200, selecting the option to wipe the data partition (do a factory reset). My device rebooted, and it started trying to wipe the /data partition, but it just stopped right there. No error or anything, the system just hung there for 2 hours before I turned it off. As I feared, the system was rendered unbootable.
However, CWN Recovery *is* still available, which I guess is a good thing. So, I can boot in recovery, but I can't really get it to function. I tried formatting the data partition again - system hangs. I tried installing the image from sd card - system hangs.
Does anybody know how I can recover from this? It seems to me that there's nothing *really* broken, just that my data partition is corrupt somehow -- and I suppose there has to be a way to recreate these partitions.
Thanks!

I've had CWN Recovery run for 24 hours now, and still nothing. It fails to format the data partition.
Anyone knows how to tackle this problem?

[Q] Factory Data Reset on Encrypted Phone: Trials and Tribulations

Hello All!
I've owned every Samsung Galaxy and both Nexus 7's and have successfully done all the basics (rooting, CWM, custom ROM) using Odin, ADB, and Fastboot. I've reached a problem that has stymied me, and Googling has thus far revealed no solutions.
Hopefully this question isn't as stupid as it seems to me.
Background
My AT&T Galaxy S4 has been rooted, has CWM recovery installed, and is running SlimBean's version of Android 4.3.
The phone was encrypted using the ROM's encryption (Settings >> Security >> Encrypt Phone). There is no decrypt option.
I installed the latest version of the ROM without realising that CWM's "Wipe Data/Factory Reset" option yielded errors due to the phone's encryption. Very stupid of me. Now, the phone works if I can get it to boot, but getting it to boot is a huge hassle that involves wiping /cache and re-installing the ROM every time.
Problem
I need to wipe data/factory reset and re-install the ROM in order to prevent the reboot problem from constantly occurring. I cannot do this from CWM due to the encryption of the phone.
Things I have tried:
1) Using ADB to mount and format system, data, cache
2) Using recovery to mount and format system, data, cache
For both, mounting and formatting system and cache were successful. Mounting and formatting data was unsuccessful.
3) Rebooting into Fasboot and using fastboot -w
For this, my Windows PC and my friend's Mac didn't recognise the device.
4) Using AirDroid to wipe data remotely
Using avast! to wipe data remotely
Using Android Device Manager to wipe data remotely
Asking my Exchange Admin at work to wipe the data remotely (maybe?)
None of these worked. The phone just rebooted like normal.
Basically
1. How can I wipe data/factory reset my encrypted phone?
2. How can I format the /data on my encrypted phone? Is this the only way to achieve (1)?
3. If I borrow a friend's Mac, and install Android SDK, would fastboot -w work on an encrypted phone?
Thanks bunches,

Format the phone completely via TWRP, and flash AMDL via ODIN. That should resolve your issue.

[Q] Can't mount /data after Quarx's CM 10.2

After installing Quarx's CM 10.2 october 30th nightly (defy, not plus) the device seemed to be working normal but I then soon noticed that no internal storage is detected. (meaning I also could not install apps from the play store) Upon restarting, I go through the entire 'first time' sequence again and any thing I did before I restarted was not saved. I think this is because, when entering TWRP and going to mount, data is the only partition that it will not allow me to mount. Attempting to wipe the data partition yields the result 'unable to mount /data'. Is it possible to mount somehow in adb or terminal? Is anyone else having this issue? And is there any known fix?

Well , I had this problem too , but not with this ROM , enter in Motorola stock recovery , and make a wipe , after that , you should flash again a SBF , and put it again.. , or if you can still flash something , try to flash the 10.2 CM again.

But it won't let me. :/ Like I said before, attempting to wipe the data partition just gives me 'Unable to mount /data'. Does that mean the partition is corrupted, or can it be mounted somehow in the terminal? This has really become a headache...
As an update, I actually was able to wipe in the stock recovery, but going back to TWRP now shows that both my data and cache partitions cannot be mounted (or still corrupted). Would flashing a new sbf fix that? I can still access cyanogen if I boot normally but it is the same as before, no internal storage and nothing is saved after reboot.

Did you try to wipe data and cache in stock recovery ? I don't know if you will flash a SBF will fix that , try to wipe data and cache too , and after that if you can't boot , flash a SBF.

Unable to decrypt data

Hello,
So I tried to install LineageOS 17 (Android 10). And there were errors. So I decided to return to RR. And what i see is that the data is encrypted and I have to format my phone. When I click on this button phone restarts to recovery(orange fox) where I have to enter PIN. And everything is fine but in logs I see this:
Failed to encrypt data.
Unable to decrypt with default password. You may need to perform a Format Data.
Unable to mount storage
I can't use my device now. After booting to system same button and text appears. Please help
Update.
When I was writing this thread I couldn't find option Format Data but when I was searching in the recovery I finnaly found it. Now everything works fine

I don't think you can flash anything without first formatting the storage . This happened for me on Redmi6pro (sakura). That was the only option left for me that time.

hope you had a back up otherwise you will lost your files.
if you had a pin to unlock your phone put that ping in the box asking for decrypt the phone. if that doesn't work you may need to format data and reinstall.
If that's the case, restart into recovery (power+vol_up)
-go to manage partitions, format data partition.
-restart to recovery
-full wipe (data, dalvik, cache system)
-flash rom (can be the same) after a format and full wipe should work well i had lineage and was great.
-restart to recovery
- flash gapps and magisk if you like.
-restart into system.
Hope you get luck.,

If you this exact text, then you can pretty much say goodbye to the data from internal storage. At this point, there no way to rescue the files... Sadly, had the exact thing happen to me & I lost all my stuff
