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

Hi guys, I'm so frustrated, I can't fix my Nexus 5. I'll explain.
I wanted to flash stock firmware and did it but now my Nexus 5 is stuck on bootanimation, I don't know what to do!
Tried with TWRP, and it says Unable to mount /data, same with CWM...
Hope you help me, thanks in advance.
- EDIT -
I fixed it, by flashing every img inside the image-hammerhead...zip, TWRP and wiping cache. The first time it booted I had unknown baseband and IMEI and like 4 fc's. Then I found this post, so I flashed it all again and now it's 100% working.
All you had to do is perform a factory reset from the stock recovery to fix it.. Or even a /cache format could have fixed it..
Anyways, glad you fixed it yourself!
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?
I am having a Yuphoria 5010 and when I flash TWRP via PC its started and even I can also able to flash Stock ROM in it. And all flashing successfully done but the device doesn't boot up it stuck on boot logo.
And if open TWRP and go to mount> "I am unable to select any of them". Also if I go to wipe> "unable to wipe anything", it says-
"unable to mount storage
unable to mount data
unable to mount cache
unable to mount system"
That cause I am unable to install any custom ROM by TWRP itself. So it may be a unique situation, I tried to format cache, data etc to all formats like ext4, ext2, f2fs, fat and It says-"DONE" but still problem remains.
And this all problem cause after somehow I get option called "ENCRYPTION or RESET" which automatic pop up on my device and I don't have any other option so I have to click on RESET and after that my device doesn't boot up, so after I try all method of Yuphoria's solution such as flashing custom ROM, stock ROM by PC, Installing TWRP and Wipe all of them and etc. But nothing works for me.
SO IF ANYONE IS THERE WHO KNOW HOW TO FIX IT, PLEASE HELP ME TO GET RID OUT OF THIS PROBLEM.
THANK YOU
Please anyone of developer reply to fix it. Thankyou
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 .
Hi all, so i didnt install any custom rom or anything, phone has all stock, today i got message "Encryption unsuccessful" i try to reboot phone if recovery and to factory reset but i got error like " Mount /data error, force format /data mount /data error. i also wipe cache but same. then i downlaod some roms to try only to update but still has error, i did even try from adb but i get msg installation aborted.
so does anyone know can this be fixed or its dead?? Thanks
srsly no one?
