TWRP does not mount encrypted storage: Password failed

Hi there,
I recently installed XZDualRecovery on my device and activated the encrytion of internal storage. Unfortunately, TWRP is unable to mount the encrypted internal storage. It always fails with the error message "Password failed, please try again". The password is correct though.
Has anyone experienced the same problem and solved it? I couldn't find any solution for this.
Thanks in advance!

Was going to ask the same question since I'm facing the same issue with TWRP v2.8.7.0. No solution?
//EDIT: Only solution is a factory reset. Made backups using Titanium Backup and I used SambaDroid for the storage data (much quicker than MTP). All good now; without encryption.

[SOLVED] Help! "encryption unsuccessful" message!

I was running oos based nougat custom rom with blu spark recovery. Then flashed official ob1, didnt like it, wiped cache/data/system and reinstalled my old oos nougat rom (audax 4.7.6). Now i get the above mentioned message..
Things i tried:
- addionally wipe internal storage and media (installed rom via adb sideload then)
- reformat system/cache/date with ext4
I googled the error and for most people (threads werent particularly concerning the op5t however) it seems that just wiping data and reinstalling the rom did the trick. Not for me though..
What can i do now?
Solution: reformating the data partition with ext4 is not enough. I had to format to FAT and right after that again to ext4, reboot to system and boom, it worked!
PS: i wonder what data is on the internal storage partition that i deleted? I didnt have any data on the phone, i just wonder.. It isnt somehow crucial to the phone?!

I think the decryption key is somehow embedded into the internal storage as wiping /data does not delete the PIN/pattern. Might be a hidden partition or something similar that is not wiped when wiping /data as long as it is ext4.

Your data is gone. It failed to completely encrypt and now there's nothing that can be done. Format /data as ext4 and let it try encrypting again

I have the same problem exactly. Can you explain in steps you have installed then format or how?

I had the exact same problem. But it is an easy fix but does require wiping your internal storage.
So the save way of doing this would be:
1. Backup all your data by going to TWRP or your ROM if that still works. Plug in an USB cable and use MTP or the adb pull command to backup your data
2. Reflash OB1 with no root (like Magisk of SuperSU) if you have TWRP. This will cause you to have the stock recovery again. I also recommend to do a clean flash (Wiping system and data before flashing the rom).
3. Download the rollback build from Oneplus [HERE] and copy this to the internal storage.
4. Boot into the stock recovery flash the rollback build. THIS STEP WILL WIPE YOUR INTERNAL STORAGE.
5. Now you have OxygenOS 4.7.5. Download OxygenOS 4.7.6 Incremental Update [HERE]
6. Go back to the Stock recovery and flash the incremental 4.7.6 zip.
7. You have the latest version now. So boot to fastboot reflash TWRP and flash SuperSU or Magisk in TWRP to regain root

Guys I did a fail, i had OB3 installed, and I wanted to try RR so I wiped system and when I tried to install I have seen error 7 saying its for dumpling not for oenplus5t.
So I restored.... But instead restoring OB3 I have restored stock Nougat rom -.- I have even stock recovery now, what is the best way to fix it?

Can i change to FAT and stay and dont go back to ex4 again?
Hi i don't know if u r reading this but if you are please help me cause I'm so lost and confused over this since yesterday...
so 2 days ago my phone started lagging and hanging and freezing until i realized i have got this issue with data encryption
i have a rooted sony z2 with TWRP Custom recovery
first i didn't know it was with data encryption failure so i literally factory reset and installed all my apps and data again and again!!! after every time my phone started to lag !!
after one whole day of trying everything i finally realized its actually with the data encryption and i should change my ex4 to something else... so here again i wiped the phone and changed to ex3 and installed and all my data and apps all over again
but after a couple hours...same problem again.....
im literally so tired of not knowing what to do ! my head hurts so much due this ugh....
i havent changed to FAT from ex3 so im wondering if it will finally solve my problem permanently if i change to FAT ??
And if it did can i just keep it on FAT forever ?
Please guide me thanks ...!

Decryption/Encryption unsuccesful

Hi, i have a problem where i encrpted my device in PixelExperience rom and every time i flash a rom i get the ecryption was interrupet/ unsuccesful error. Now im flashig miui to see if it helps, formatting data in twrp doesnt help, but twrp can see contents of the internal storage and decrypts it with default password. Please help me

I can only boot succesfully if i restore my PixelExperience backup and remove locksettings.db from /data/system/, and i cant boot any other rom even after formatting data in twrp. What can i do now?

Question: Howto understand the TWRP encryption problem

Hi guys,
I'm a little bit confused about the TWRP problem to mount encrypted data partition.
My Lineageos ROM and TWRP combination, I had the last years, were all encrypted and I had never problems decrypt data with TWRP and my password.
Now I switched to A5 and it's only possible to encrypt my phone or, to make backups with TWRP!
All threads I found about "can't found crytpo footer" or "can't decrypt /data" were the solution to format data. But I want to keep my encryption to keep my phone more secure! For remove the stock rom encrytion key, ok. But not for daily usage.
I'm on Lineageos 16 and TWRP 3.3.1. My A5 2017 is on the latest firmware A520FXXUBCSHB.
Please enlight me, may I sort something wrong, or something important has been changed on newer devices!
For me it looks like:
Encryption on = Data Encryption on + TWRP Backup off
Encryption off = Data Encryption off + TWRP Backup on
Is it possible to get both, encryption and TWRP backups? Or to get fix for TWRP?

Unable decrypt FBE device

I flash rom EU stable v12.0.3 on my redmi note 9 pro 5g, after time of used, i wiped dalvik, cache, data without sign out of my google account. The system reboot and show a notice that my decive was not certified by play protect.
I flash china rom v12.0.3 by miflash and flash twrp 3.5.2. But it cannot decrypt storage.
I flash china rom and twrp again, the same result. What's happen with my device and what can i do now. Thanks for your help so much.

Did you format data? This is different from wipe data
Format data is the option on the right next to advanced wipe option.
Formatting data removes encryption so backup anything on internal storage first
After formatting data reboot back to recovery
If all else fails flash stock firmware via fastboot and start again

After many times format data and try to connect with 3 pcs, i had an eu dev rom on my device. Because stable eu rom still notice about play protect. Hope that next eu stable rom will fix it.
Thanks bro alot!
