Ever since I updated to Android 10, I haven't been able to mount the data partition in TWRP. I'm using the newest TWRP version. Does anyone else have this issue? And have you been able to fix it?
I've already tried the following:
- Removing any for for password
- Using password
- Using PIN code
- Wiping the phone through TWRP
- Formating the Data partition (After formating I can mount the data partition, but after booting the system, it can't be mounted again...)
- Changing to ext2 and back to ext4 (Had same result as formatting)
- Normal Factory Reset
I have absolutely no idea what is wrong. Any help is appreciated
Are you using twrp 3.3.1-70, 71 or 72? These are the modified version for the one plus 7 pro. other version will have problems.

I've managed to get that awful Rom (Destroyer) Manager off of my TF101G and have got Rogue on via PERI and now I'm trying to flash the stock ASUS ICS Rom but can't delete the Dalvik Cache because I'm unable to mount /data
Code:
- - Wiping all user data - -
Formatting /data...
Formatting /cache...
Formatting /sd-ext...
Formatting /sdcard/.android_secure
Cache wipe complete.
Formatting /cache...
Cache wipe complete.
Wiping dalvik-cache...
Error mounting /data!
I'm assuming that /data is stuck on read only?
Manually fixing permissions and then mounting /data also shows the same error.
HELP :crying:
I have the same problem. I know what lead me to it.
Its an Asus SL101
I have cyanogenmod correctly installed. In order to install a megatron rom I downloaded their app called megatron apps. Trying to download a rom from them I got validation error at end of download and I make the stupidity of change the download dir from /mnt/sdcard to /sdcard and then when I restart again it doesn´t load and CWM recovery give me the same errors (unable to mount /data or unable to mount /sdcard when cleaning cache or trying to restore a backup ).
The only thing I have been able to do its to install Rogue XM Recovery 1.5.0 instead of CWM 6.x ) but the problem to apply an update or restore a backup persists.
Any idea ?
Aaargh.
After a year and a half of heavy CWM and TWRP usage, this has suddenly happened to me too, possibly after flashing the updated TWRP blob from Goo Manager (although that's conjecture at best). My ROM (RaymanFX' CM10 v6) is fine in everyday use - no problems whatsoever, but now I want to update, and my recovery won't let me.
In the hope that something simply went wrong during recovery blob flash, I successfully deleted TWRP and flashed a different recovery (latest CWM) from ROM Manager, but the new recovery can't mount anything either - neither sd card, data, or cache. The error messages are more or less identical to TWRP's errors. My system MAY be readable, but I can't backup or restore or flash anything anyway, so I don't dare format it.
I don't have a Windows PC, so I haven't tried Easy Flasher. I could try it on my work computer if there's no way around it and if neither OSX or Ubuntu can help.
Any suggestions?

Erasing those partitions didn't break your phone, so don't worry! Most people format those when performing a reinstall of a ROM (most people don't format the SDCARD though since you lose all your personal files!). Now that you've erased them you have to flash a ROM before you're device will boot. The system partition is where Android is installed. By formatting the system partition you basically erased your installation of Android and all your apps/games (data partition) along with it.
Now just flash your ROM of choice as you did originally to get to Cyanogenmod and then make a backup!
Hey all. I have a rooted TF700 with CM 10.2 on it. I have encrypted the tablet (via SETTINGS - SECURITY - ENCRYPTION). I'd like to do a "Factory Data Reset" - it's my understanding that this will remove the encryption, along with all my user data. This is what I'd like to do.
However, when I go to SETTINGS - BACKUP & RESET - FACTORY DATA RESET, it doesn't work. It asks me to enter my password, then asks me to 'erase everything', and when I click it, it reboots as if to perform the reset. I get the little android guy after it reboots, then the ASUS screen, then CM boot screen. However, the tablet boots like normal, is still encrypted, and all my user data is still there.
I recently upgraded from CM 10.1 to 10.2 - getting the gapps package to install took several tries for some reason, but eventually it worked. I have clockwork recovery installed, but because the tablet is encrypted I am unable to mount or format the /data partition from clockwork.
Anyone have a clue how I can get the 'Factory data reset' to work, or otherwise decrypt my tablet? Thanks!
Factory reset is done by your recovery. Which recovery (and version) is currently installed? Maybe you need to choose "format data" explicitly in the recovery.

I cannot touch (either mount or format) /data from Clockwork recovery because it is encrypted by android. any attempt to do so, and I get an error
"ERROR cannot (mount/format) /data!"
doing the 'Factory Data Reset' from within Android is supposed to decrypt and wipe /data, but that is not working.
I flashed TWRP and got rid of Clockwork recovery - that enabled me to mount /data in recovery (TWRP asks for my password to decrypt /data when TWRP starts), which is something. However, when I go into /data using the terminal I only see the lost+found directory and nothing else?
However, formatting /data from TWRP doesn't work, neither does a reset. They just give me errors.
I then tried abd shell - mke2fs -T ext4 /dev/block/mmcblk0p8
but that gives me a '/dev/block/mmcblk0p8 is apparently in use by the system; will not make a filesystem here!' error, even after unmounting it manually (umount -a)
Next, I tried using TWRP to reinstall CM 10.2. After that, the boot process took 40 minutes or so. Once it came up, there was no user data and cyanogenmod was fresh (yay!) - but the partition is still encrypted - it asks for password during boot, even though the OS has no password lock on it.
In addition, my WIFI is now not working!
anyone have a clue here? I REALLY want to remove the encryption on the /data partition!
I wanted to follow up here with closure. Im not exactly sure WHY what I did worked, but it did, and maybe it can help someone else.
last I left off, I had CM11 installed, but no wifi, and the partition was still encrypted. At this point, I decided to try to downgrade again to CM10.2
Now, when the tablet was booting, it was asking me for my password to decrypt so it can boot. Except now, after loading CM11 and going back to 10.2, the password wasn't working and couldn't boot. I was convinced I was bricked.
I went back into recovery, and reloaded CM11. This time, when it came up asking for my password to decrypt before booting, it worked. So something in CM11 changed the encryption on /data so that CM10.2 couldn't read it anymore.
once I was booted into CM11 (still with no wifi), I went to SETTINGS - BACKUP & RESET - FACTORY DATA RESET again. This time, it worked! Asked for my password, said are you sure, then rebooted. BOOM, /data was no longer encrypted! CM11 came up, and with the fresh /data partition, wifi even worked!
For other reasons (Netflix) Ive since gone back to 10.1, but now /data isn't encrypted, so wiping and flashing is easy and works great now.
It seems there is a bug in CM10.2 (or android) where the FACTORY DATA WIPE doesn't work with encrypted /data partitions, but CM11 was able to do that just fine.
Hi,
I wanted to reset my 510 to a fresh 4.4.4 install. So I decided to "restore to factory settings" within the android system settings menu.
kitkat CM12 4.4.4 by shreps was working fine before, I just wanted to get rid of the data in order to give the tablet away.
now I'm stuck with a soft bricked device, it seems:
- when starting the tablet, the CM screen shows, but freezes after a while
- flashing any CM version in CWM 6..0.5 by shreps shows a "error: can't mount /data"
- wipe cache / data shows the same error
- wipe dalvik cache doesn't seem to respond in any way
- I reflashed CWM 6.0.5 using fastboot flash recovery, but to no success..
what options do I have now? can I format and remount the /data partition via ADB? do I need to go to stock?if, so, how?
Thanks for your ideas!
ok, via
fastboot -w -v
i could reformat the data partition somehow.
I still got an
E:unknown volume for path [/sd-ext]
error, but it continued and works for now.

Glad you dot it going.
I just pulled my 701 out of retirement (broke my Sony z2 screen trying to change my battery) so taking a look in here.
The data format has always been a bit twitchy, but I run the latest version of TWRP for KK. I remember bricking my original Data partition wiping it because some bozo used the wrong partition info making the original recovery for JB. Exchanged the tab.
I recall the bootloader version had to match what version of the ROM you installed (JB, KK, etc), and maybe the recovery also (can't remember). Latest TWRP for KK seems to work for me as I installed Pac Rom before I retired it. TWRP Ver 2.7.1.0
As with the "Path to ext SD", that's always been there if I recall. Just means you have to install a ROM from internal memory. Although my TWRP seems to mount it fine.
But I will say, feels like I've entered the dark ages again.
Hello,
i Have recently upgraded to android 10. When flashing twrp i get a message failed to mount system partition. If i reformat system to ext 2 then back to ext4 i can mount system in twrp. When i re flash latest factory pixel 2 image and go back into twrp i can no longer mount system again. Is this some new thing with Android 10? Without it mounted i can not access my system partition with root explorer or other root apps. is there a way to force system to mount after flashing a new image?
After reflashing with magisk system was mounted somehow. Not sure how this happened.
