Mi A1 Forced Encryption

I'm sorry if this is posted again but I can't find anything about my problem.
My Mi A1 in unrooted.
I had installed gcam without rooting it to continue receiving OTA, after the latest update I wanted to disable gcam. During the process the application unlocked the bootloader but didnt lock it again.
When I disabled it after the reboot my phone did a factory reset and enrypted itself. I want to decrypt my phone so I used some ways I found on the internet like:
Simple factory reset.
Locked bootloader.
Factory reset again, even though after the lock it did it itself.
Flashed fastboot stock rom.
Flashed twrp read only, wiped system and flashed fastoboot stock rom again!
Still the phone forced encrypt itself after every way I tried:
For gcam I used this way: https://forum.xda-developers.com/mi-a1/how-to/tool-google-camera-root-magisk-enable-t3747585
I didn't check the thread because I already had the app to do the installation.
For fastboot installation I used this: https://forum.xda-developers.com/mi-a1/how-to/ota-official-fastboot-image-n2g47h-7-12-t3728929
EDIT: What if I unlock the bootloader with MiUnlock and relock it via fastboot?

Phone is encrypted by default. Why would you want to have it decrypted? But if you insist.. you have to install magisk, disable forced encryption and reformat data partition in TWRP.

Locking or unlocking the bootloader after May update wipes your data, this is normal for Android and now our phones.
Encryption is default, it would have been encrypted before the wipe as it is now after the wipe, why do you want it unencrypted?

Thank you very much, I never experienced this again after unlocking so I thought it was because of the encrypt, I hadn't checked if it was encrypted before the wipe and I assumed it wasn't.

I didn't know the phone was encrypted by default.
Thank you for the possible way though.

Yeah, it is encrypted by default and hw encryption is used. So don't think that it can affect your performance in any way.

After reformatting data partition, do I need to do anything else?

Keep Magisk installed, otherwise it will probably get encrypted again by stock boot image. Not sure, I didn't try it.. I want my data secure.

LineageOS 15.1, default encryption pin/key?, no mount on TWRP

Hi, sorry for my bad englich,
i have install LineageOS 15.1 and GAPPS (it is a lidle bit tricki, but ist works after that i have no pin protection to phone und eable encrytion filesystem, i was not ask to pin/key for that, encrytion was finished, reboot of OS work fine. Then i secure the phone with a pin, all works fine, reboot, unlock...
Bevore i update to next new lineageos OTA version i would make a backup, but twrp can't mount filesystem and ask for pin/key to mount. But my pin don't work???
What key use encrytion without display lock pin on default???

Hi,
TWRP can't decrypt the data partition when it has been encrypted with Oreo.
If you want have an encrypted data partition, you will have to go back to LOS 14.1 (format the data partition before!), then enable the encryption there.
Afterwards you can upgrade to LOS15.1 again. Important: Only perform a "Wipe" of the data partition, do not format it again (upon formatting the encryption gets lost).
Alternatively you can wait until TWRP will support Oreo encryption, but no one can tell you how long this will take.

thanks for info.
this is a not a bug, this is a function
I hope this will implemented, although the phone is getting old.
I will probably make your way over 14.1 for testing.

Trebleizing + Encryption

Hi guys
I currently have stock encryption on my phone and running lineageos 16. I want to trebleize my phone. On one thread it says that I should format data to remove encryption but on others it doesn't say to.
Can anyone confirm that I have to remove my encryption?
Thanks

Yes, you should format data via TWRP to remove encryption

Decrypt mi 9t global/eea

Hello everyone,
How I can decrypt mi 9t with global/eea ROM?
Which recovery I have to use?
And what steps should I do?
Thanks

Simply remove your lockscreen security. Once you done tbat, encryption is gone. However, if you factory reset while you still had encryption (lock screen security) you have no other alternative than wiping your internal storage.

Youre wrong. If You remove lockscreen security Your data is still encrypted. You can check it in Settings,Addatoonal Settings,privacy,encrypt phone.
Only way to remove it is format data but beckup Your data first to computer or USB drive otg.

I'm currently using the 4pda twrp and formating Data does NOT decrypt the Partition for some reason. I even got the xiaomi.eu and havocOS working in encrypted Mode before. Ist there anything I am Missing / can decryption bei done manually? I dont want to run into problems later on.

renable encryption after format data

what to flash to reenable encryption after flashing magisk ?
