I have the following problem with TWRP. When i boot to TWRP the language is set to chinese and the internal storage is 0. Also, no password is asked in order to decrypt the data. I tried to change the password (pin or phrase) and it didn't work. I have also tried the method that change the mount points and repair. Has anybody faced the same issue?
Which TWRP ? And what rom are you using ?

Hi XDA,
I used to try out every new ROMs out there and today I just did the same. I downloaded and installed Dot OS and now the device's internal storage is not accessible. When I try to wipe the data it says unable to mount storage.
Nothing is found on the file manager.
I can't download anything from the internet since there is no internal storage available.
But it is available from Red Wolf a recovery mode. I can see all the files from the recovery but not able to see or access it from the file manager.
please help. Now I can't install new ROM since I can't download new one.
I haven't tried factory reset yet. Please help me if I can do something on the device or inside the recovery.
please help
Wipe everything through Recovery EXCEPT internal storage. Then there are three things you can do:
1. Try flashing any ROM you have saved in your internal storage.
2. If you have saved some ROMs on your PC (good habit), you can flash one using Adb side load.
3. Download a ROM using someone else's phone and use either a microSD or USB-OTG to flash it.
Found any fix for this issue
Because I'm also facing same problem
security
Flash any custom rom before remove all password (fp, pattern, pin, etc)
This is just an encryption problem you have to decrpt your phone. If your phone is encrypted your twrp will ask your password to decrpt and you have to remove password or pattern from twrp go-to youtube and search for how to remove pattern or password from twrp watch vj mehta's video and do it and enjoy but all file in internal storage will deleted so you must copy everything before you doing this ok
I'm on Android 10 (Xiaomi EU ROM - MIUI 12). My phone is encrypted, still I can access all my files inside /data partition and internal storage (which is inside /data too right?).
When I boot into TWRP recovery mode, it asks me for decryption password. If I provide password, it does decrypt, that's good.
BUT even if I don't provide password, still all files are accessible. how is that possible?
also if the device is not encrypted somehow (bug maybe?), then what exactly TWRP decrypt when I give the correct password?
Helo! I will explain the case.
Device: Samsung Galaxy S Duos S7562
Custom ROM: Lineage 15
I selected to perform device encryption in the default option of the system, after the whole process, the phone got stuck in the Samsung logo and won't start. So I accessed the TWRP and saw that it is not possible to access /data and it is also not possible to clean it.
Through the computer I can't get the device to be recognized by the ADB.
Is there any solution or can I schedule the wake?
TWRP >> Wipe >> format data >> type "yes" .
It appears the ROM does not support encryption/decryption, the phone is indeed encrypted, but the problem is when trying to decrypt the data, it seems to fail.
If you had any important files, there has been some tutorials on decrypting /data in TWRP using the decryption password.
Mohamedkam000Thanks for the tip. I went to research and found this tutorial. It worked for me from step 8.
I found it on another site, I don't know if I can quote the source here, but here are the steps, in case someone else needs it:
1. The first thing to try is whether the internal storage was somehow encrypted using a legacy screen lock method.
2. Go to Settings > Security > Screen lock of your Android device and change screen lock method to Approved or Pin. Create a new one.
3. Reboot into TWRP, and it should ask for a password - enter the pass or pin you just created.
4. TWRP will attempt to decrypt your device's internal storage and, if successful, you should have no further problems. However, if that doesn't solve the “unable to mount data, 0mb internal storage” issue, continue with the rest of this guide.
5. Reboot your device into TWRP again.
6. Navigate to Clean > Next Clean > Data and choose Repair or Change File System.
7. Press Repair File System to see if this resolves the issue. If not, continue.
8. Press Change File System, choose Ext2 and swipe to confirm.
9. Now go back to Ext4 and swipe to confirm.
10. Go back to the TWRP main menu, then to the Mount menu and check if your partitions can be mounted now.
11. If you are still unable to mount your partitions, you will need to repair the internal partition, which will likely clear your internal storage.
There are four points to clear it out:
For /data partition to show 0 MB, or failed to mount, it doesn't mean it has broken its filesystem, it didn't, it's just encrypted, that's how the protection works.
Choosing to repair filesystem or change filesystem may result in a bootable/mountable filesystems, however, you'll lose your data. Not all phones has decryption on TWRP, it needs a modified recovery.
Encryption has different security key than the regular lockscreen, it doesn't use pattern. So it doesn't matter what you've set on your lockscreen.
It seems to be your first time encountering this issue. On modern phones (S6 and above), when you flash TWRP, you won't be able to mount /data, because all phones come with forced encrypting mechanism, so in order to flash custom ROM, you'll have to format data (the option where you write "yes"). And any mount of /system will result in a bootloop haha.

Thanks for the information. Next time I'm going to look for an encryption-compatible TWRP.
hi, just want to know why my phone data are crypted....never put a code on it....
I just try twrp at startup, it ask me a password for user 0, password I never enter, so I pass and go to format data, but got error 255, unable to wipe data, unable to format to remove encryption...I go to mount and can mount almost all partitions execept data..I return to wipe and got multiple errors with same result...
when I go on twrp in data/media/0 I have many folders with numbers and letters..
so on fastboot I set fastboot erase userdata so start again setup and on TWRP, I can mount data partition but can't still not format data, got error 255 and in data/media got same strange folders.
how can I solve it..thanks
maybe important thing, my twrp recovery is not installed, I just boot on it with fastboot..
try to boot to system, set a pin code.
go back into twrp and then you should be able to decrypt with the pin you added.

Hello,
I own a Xiaomi Redmi Note 10 Pro (sweet). Its bootloader is unlocked and I use TWRP 3.6.1 as recovery. The problem is that when I install a rom (EvolutionX), everything works until I reboot to TWRP. At that point, my recovery is unable to mount the phone's internal storage and it shows as 0 bytes. I have followed a few help topics already, which stated that the solution was to change the data partition format to Ext2, then back to Ext4. However, this makes my phone unable to restart to system. The problem is that when I format my data, the data partition is by default formated as f2fs. I'm guessing that any other data format makes it unable to boot.
So the problem is:
When data is formatted to Ext4, TWRP is able to mount my phone's internal storage and install roms. However, in that case, my phone won't boot to system.
In the other case, my data is formatted to f2fs, which makes my phone totally functional, but my recovery useless. Which means I can't root my phone or update it.
What could I do?
Thanks in advance.
are you mixing up file system type with encryption? if your android is 12, TWRP is not able to decrypt (yet). then just disable encryption and format userdata f2fs (unencrypted).
otherwise claim it to TWRP maintainer he forgot f2fs support.
