Problem with encrypted phone / unable to decrypt phonencryption

[thrdroom]

Problem/Bug:

When i encrypt my X5 CyanogenOS i cannot longer use TWRP to backup, flash etc.
TWRP is asking for the password to decrypt, but even with the right password TWRP is unable to decrypt the data.

Error Message in TWRP:

Updating partition details...
...done
Unable to mount storage
Full SELinux support is present.
Failed to decrypt data.

Steps to reproduce:

1. Flash clean CyaogenOS image (cm-12.1-YOG4PAS9OI-paella-signed-fastboot-08a5c4b830.zip)
2. Flash newest TWRP image (twrp-3.0.2-1-piccolometal.img)
3. Set a password for the lockscreen
4. Settings app -> Security -> Encrypt phone
5. Boot in TWRP -> TWRP tries to mount the data-partition -> Enter password

Thanks for your reply @Kra1o5

Thats awesome! Can you give me an ETA for this release cause this problem bugs me for months now and i cant do any critical testing like e.g. CM13-nightlys witout a full-system backup.

Last update is nearly 5 months old.

I will try to get new update asap.

[thrdroom]

[Kra1o5]

@Kra1o5 THX for the Update 👍 But the problem persists even with "twrp-3.0.2-2" :(

Failed to decrypt data.

Can you please fix this issue? Ive been waiting for so long :/

[eloimuns]

Probably only work with stock X5.

[thrdroom]

Do have the stock-rom Installed? Can you test this @eloimuns ?

[thrdroom]

Problem does not persist with CyangenOS 13. But is still present with CyangenOS 12.1, which is kinda annoying as it makes updating an encrypted device without a full wipe impossible.

[Kra1o5]

Oh, yes

The fix affect 13.1

I have the same problem.
At Moment with the I think early March LineageOS build and with newest TWRP.
It would be perfect if it would work.

same problem at TWRP 3.1.0-0 and actually LineageOS_14.1 nightly_build (03-23).
TWRP is unable to mount encrypted phone, the right password will not accepted.

So at the moment I can´t install updates and making backups.

[LineageOS-User]

No one who can take care of this issue?

[Kra1o5]

If you use stock firmware as base will not have any issue with encryption and since CyanogenOS not exist anymore is the best idea.

Sorry I don't get this. What do you mean with standard firmware? Do you mean the factory default Android? But I am using TWRP to run LineageOS and in the moment I am desperately waiting that I can backup my encrypted device und update it again.

Download the stock firmware from https://www.bq.com/en/support/aquaris-x5/support-sheet and flash these files. It will replace all your data, so make a backup.

Alternatively, edit the included script and skip flashing of system, userdata etc.

Once this is flashed, you can install TWRP and LineageOS again and as usual...

Thank you very much. Indeed it worked, although it was a time consuming task.

Issue can be closed. @8FordPrefect8 thanks for your feedback!
