I have a galaxy pro 12.2 rooted with CM12.1.
I tried to install a nightly but I couldnt wipe the cache. The console always says "can't mount cache"
I tried it 300 times and rebooted 300 times and it wouldn't mount.
After googling for a little bit, a majority of the pages I found said TWRP isnt stable with partitions and I was supposed to choose rm -f instead of formatting the partition or it corrupts the partition.
I'm assuming this is what happened to me because I just wiped the cache instead.
I wiped the cache and dalvik and system and did a factory reset and then I installed the nightly. It would boot but then it got stuck on the boot screen. So I tried to clear the cache again but I got the same error.
Then I reset my phone and wiped /system and data but not cache because I couldnt mount cache. And then I installed a stock rom. This rom also gets stuck on the boot screen. So now I have a tablet with a stock rom installed and what I'm assuming is a corrupt cache partition.
Also, I did back up before I installed the nightly. I have a working backup on my phone. It worked fine when I used it and it gave no errors when I backed it up and I got no errors when I restored it other than cant mount cache.
So I tried to boot into my working backup too. Still didnt work.
How do I fix this?

Been running CM10 and CWM 6.0.1.9 for ages with no issues and loving it. Yesterday morning (while on vacation) picked up the tab from charging and it was boot looping. Tried formatting cache and Dalvik cache as 1st attempt to fix and it reboots when trying to format Dalvik cache, regular Cache deletes just fine. Next reflashed CM10, but still boot loops. Started manually formatting partitions and when I get to Data it reboots.
So this sounds like Brick Bug, but shouldn't be since I'm on CM10/CWM6.0.1.9 and wasn't wiping when it occurred.
So questions for the braintrust...
1) Is there anything I can do to fix this while on vacation when the only PC I can access is Windows RT? Basically it needs to be something I can flash with CMW.
2) Assuming #1 isn't possible, my next step was to try flashing a stock rom when I get back home. Make sense or other thoughts?
Thanks,
Todd
try removing your ext sd card and boot it up. See if that helps. If not, I'd Odin the stock ROM
I have experienced this too. My fix was to delete data after reflashing CM10. I tried just clearing cache and dalvik like you did but it continued to boot loop. So I flashed CM10 because I was at school and it was all I have but it was still stuck and so I cleared data at CWM(Didn't flash CM10 again anymore). And yeah, it pretty much deleted everything, but I had a backup at home. It was fixed.

Thanks. Formatting data causes a reboot, so I think I'm stuck until I get back home and can use Odin.

[SOLVED] [Q] [P6210]Boot Looping and Corrupt Data Partition
For the sake of the archives...reflashing stock Honeycome fixed the partition problem and allowed me to re-install CM10.
Hey,
I've been running several Lollipop ROMs on my Nexus 5 in the past few months.
Today my Nova Launcher suddenly stopped working and froze instantly on restart, so I rebooted the phone.
It got stuck shortly before ending the boot, after several seconds of those colored dots whizzing around the screen they froze.
This issue was reproducible, so I first cleared the Cache and Dalvik Cache and rebooted, same problem. I then tried to Fix Permissions to no avail.
I then erased System, Data, Cache and Dalvik Cache and reflashed my current L-ROM of choice, OptiPop.
The device still doesn't boot, same problem.
Now TWRP is showing an error in red font whenever I try to wipe or flash.
The error I'm getting is:
Code:
unable to stat '/data/data/com.google.android.feedback/cache/com.android.opengl.shaders_cache'
Does anyone have an idea on how to fix this?
Try reflashing TWRP and then wiping. If it still doesn't work flash the factory images from fastboot using either the script or ( optimally ) by hand one by one.
Your filesystem might have gotten corrupted well enough for TWRP not to make heads or tails of it.
If that still doesn't work search the forum for how to format the needed partitions - and triple check what you are formatting.
hey guys
i was installing cm12.1 nightly and i though to fresh install it. so i opened twrp and swiped dalvik cache,cache and data but factory reset failed for some reason.i found out that twrp couldnt format data.so i googled it and found that changing file partition system can overcome this problem so i changed the file partition system to fat. then i tried to install cm12.1 but it got stuck in the boot animation.
then i again tried to factory reset but this time i got error 'unable to mount /data'
i tried cwm and touchwiz recovery but both of them couldnt even format data as it was un mountable
so guys can you help me as my phone is lying dead now and there's nothing i can do about it
if you need any log /screenshot pls let me know
hoping for working solution
having a good day
so i wanted to backup my oneplus one using twrp 3.0 and for some reason i decided to wipe the cache before i backed it up. I went to wipe (just the regular cache) and it kept trying to wipe but it never succeeded so i just forced rebooted it went back to twrp and backed up my phone. Once the backup was done i tried to boot it up and i was met with a boot loop. Then i kept rebooting my phone and no luck. then i tried to completely wipe my phone. well just a factory reset. it didn't work i was greeted with an error saying my cache is not mounted or something like that. so now i cant even wipe anything at all and i think twrp has a feature where you can access files from recovery and that doesn't work for me. adb isnt working either i was trying to push a file. What im trying to do is flash a newer version of twrp or try to adb sideload my same rom. but i dont have access to my same rom cause the links are down. my rom is minimal os btw. any ideas ?
Edit: I've fixed the problem by booting into fastboot and flashing a newer version of twrp 3.0.2. then i wiped the cache and it was successful. then i booted up and it works!
Hello, thanks for your help.
It seems I bricked my galaxy s7 while trying to format the /data partition.
I installed TWRP 3.2 and a custom rom, and everything went smoothly until then.
I tried installing an audio mod which throwed a " can't mount /data" error, searching for solutions I read that formatting the data partition to fat and back to ext4 should solve the problem, I tried formatting it to fat with TWRP, however on the first try I got a message that it suceeded, followed by a message that /data could not be mounted, TWRP seemed to be still working (there was no reboot button or any other buttons, just a "working" bar). After giving the phone 3 hours I decided to restart it, now I can't access TWRP; it stays on it's "splashcreen", and of course the phone won't boot.
I'm having a rough time with this so I will appreciate it a lot if you can help me.
Thank you.
Boot to download mode, flash stock firmware using Odin, then retry the TWRP installation.
For wiping data, you have to make sure you use the wipe option that makes you type out 'yes' to wipe, the other factory wipe methods don't actually properly wipe the partition.
iirc you also then need to flash the dm no verity zip from the TWRP thread.
Bro you didn't have to do anything but just formating the phone in the first place. Aassuming you're on oreo , it happens to a lot of people and myself, after flashing a kernel twrp was unable to munt data, all i had to do is a data format in twrp that fixed the problem .
