Unable to mount /data

Hi All, i have been trying to flash rom but it keeps restarting back to recovery. I have flashed stock recovery, did wipe and reinstalled TWRP and still the same. I was earlier getting message unable to mount /data. I have tried wiping only data and also tried mounting it via USB connected and it works but unable to flash any rom. Please help.
Edit: I have tried TWRP 3.0.2, 3.0.0 and 2.8.0.1

Any help appreciated. When i flash rom from external card it reboots recovery but when done from internal it says unable to mount data rom works but partitions are not the way they should be. Have i bricked this?

@Entropy512 please help

Is there a way i can remap all partitions?

guys i am out of ideas. Please help. I can boot into recovery and bootloader. I can switch recovery. I have also tried to flash stock recovery and stock rom, nothing is working for me.

put the phone in fastboot mode and then try to format the data partition from there with "fastboot format data"

Ended up in a bootloop during restoring twrp backup

I was on pixel experience rom and wanted to try out other pie based roms on my device. So i backed up all the partitions from twrp recovery and went on with flashing arrow os. But when i wanted to revert back to pixel experience by restoring the previously made backup, it showed that system partition mount was failed during the restore process. So i tried booting into twrp again but the device just bootloops. I tried entering recovery mode by using volume up and power combo. But twrp starts bootlooping after the logo appears on the screen. I also tried flashing redwolf twrp but it also fails to boot. Any help would be appreciated.

I already did that. But the result was the same.

Try this:
Go into twrp, wipe, advance wipe, select system filesystem only and the option to repair/resize file system and repair it...

I flashed the fastboot rom. It is working fine now

seems like /data partition encryption / decryption issue!
fastboot rom reset everything! so you are fine now!
if you ever stuck in such situation again!
boot in to ORANGE FOX recovery 8.3 (NOT From recovery parititon!) - load it as FASTBOOT BOOT recoveryORANGFOX.img and let it boot .. goto partition, and change format DATA , YES and do it, if it doesn't allow (OR IF IT DOES ALLOW) the next step is to select the DATA partition again and change the file system from ext4 to xFAT, it will give error, NOW again change the FILESYSTEM of DATA to ext4, you will see that even after error the DATA partiton was set as xFAT and now back to EXT4. do the SAME with /SYSTEM (if necessary)
power off the device from recovery
boot recover again (fastboot boot recovery orangeFOx.img ) and FLASH the custom ROM you wanted to!
you will be fine!

I experienced that too.. i think some ROM does something to vendor partition, example:
1. You backup data,system,boot etc...lets say u do that on "A" rom..
2. then u install "B" rom, and u like not satisfied on that..
3. Then u wipe everything and restore your "A" backup..
if you do that like what i said.. you will ended with bootloop or just stuck on mi screen..
I found a workaround ..
You just need to re-flash the "A" rom (clean install), then wipe everything again , and restore your backup..
? Sorry for my english btw

In my 16GB model, when I did a recovery through TWRP, I had a bootloop problem.
However, 'OrangeFox Recovery' does not cause this issue.
And, SD card with 'exFAT' format is recognized as normal.
I strongly recommend.

[HELP] im stuck with no os and mtp wont work in twrp and also ADB isnt working

i flashed miui 9.3.28 and then booted twrp , but it was asking for password so i went to wipe and repaired data using ext4 ,and then procceded to wipe data, vendor, cache, system and now im stck with no os and i cant use adb sideload to install a rom please help :crying: :crying: :crying: :crying: :crying: :crying: :crying:

Reboot into fastboot(keep pressed power and vol - buttons until you plug cable to pc otherwise it can start rebooting system) and flash latest fastboot miui(you need to unzip it first): http://en.miui.com/a-234.html via XiaoMiFlash tool with clean all option. If you can't see your device in tool press refresh in MiFlash tool you have also Driver section check this. Another option is to install google latest_usb_driver via device menager(right click on your device->update-driver->browse pc -> and select usb driver.

I got the exact same problem after flashing the same beta build. Nothing worked for me so I had to flash the fastboot image and roll back the stable channel.

Op next time don't wipe vendor partition.In your case you should get recovery with supports MIUI on androind 9 and if ou had encrypted data you should format the data. Here you have similar situation: https://forum.xda-developers.com/redmi-note-5-pro/how-to/recovery-pie-update-miui10-t3916963 (I didn't try this one)

Remember For decryption it only needs to format data partition only.
How will it boot if you wiped system as well as vendor partition.
If you can get in recovery just flash the update file 9.3.28 and u r ready to go.

I did all that and formatted the data partition which was decrypted afterwards. The problem is that internal storage gets re-encrypted after I boot to system.

Can you give the version of twrp which worked in Pie.

Regarding your problems
Copy any rom to a micro sd card and flash it through twrp if done ur done

Try using OrangeFox Recovery, I had the same issue ADB & MTP connection with TWRP for Whyred.

Thanks. My main problem was that mtp driver of Miui was wrong. And the decrypt error was solved by Redwolf recovery. i have yet to try OrangeFox one.

MIUI 12.5 Data Encryption

MIUI 12.5 Encryption is very different. I am now unable to decrypt data in any Recovery.
As usual, I formatted data, wiped System, Vendor, Data, Cache, Dalvik Cache. Installed MIUI 12.5 China Open Beta. I don't like it. So I went to new TWRP, I disabled MTP and Formatted Data, then I flashed Havoc-OS Custom ROM (usual process), setup it. I went to recovery again, and it was not able to decrypt the data. I thought to change the ROM. I went to Fastboot and Formatted Data via Fastboot: fastboot erase userdata. It's success. I went into recovery and installed Resurrection Remix 8.6.5. I setup it and started using it. I went into recovery and so that it cannot decrypt it any more. What ROM I install, or what recovery (tried two ver. of TWRP and OrangeFox R11), I am unable to decrypt /data on Recovery. It's working on ROM and I can boot. Now I can't even access /data on Recovery.
Anyone please help. Have anyone faced this problem?

I think that you must use a recovery like twrp_ginkgo-willow_RN8-T_3.5.A9_11-01-2021_bl-l from geoanto555

You saved me with this recovery.
Cheers.

I was indeed saved by this revovery as well. However, I flashed Magisk 19.3 and it did not root though the dialogue said it did. I was unable to open Magisk Manager from app drawer.
Is there a specific Magisk to use with this particular TWRP?

Question (Please help me) Mounting problems

Hello,
I recently tried to flash a custom rom on my poco f3, but I couldn't install twrp, because I didn't have the option to install it when i boot to it.
So I followed some instructions online and formated data partition to ext2, and then back to ext4. Now I can't copy any files to the phone storage and can't do anything else.
I can reboot to fastboot, and I can boot to twrp, but it's pretty much useless because I can't sideload anything, and can't install twrp anyways.
Did I do something wrong? Is it easily fixable?
Thanks in advance.

I don't understand what you mean, sorry. I'm newbie.
Should I format the data partition to f2fs？

Idk depends on ROM. MIUI is f2fs

Oh. I tried a different twrp version and could install it on the phone. Now flashed crDroid and it said my system was broke so had to factory reset. It is working now. Thanks.

But now I can only access the crDroid recovery, how can I install back twrp? if I try to fastboot boot twrp.img it simply reboots back to system.

try to boot TWRP from other slot maybe? (don't forget to switch back)
Code:
fastboot --set-active=other
fastboot boot twrp.img
if that fails just flash TWRP into vendor_boot partition, and restore vendor_boot.img from crDroid right after
