Change Encryption to "new standard"

You do not need encryption support in the recovery to do installs or updates.

Thank you very much AnotherElk & chrmhoffmann!

“Possible” in the sense of “don’t count on it in practice” .

Oh, it worked well for me. The decryption took a “long” time (approx. 10 minutes, I thought the app crashed - in the end it was successful) but I was able to navigate through the storage and install the LOS 17.1 update from the encrypted storage. In the future, I’ll consider that maybe I just got lucky.

@AnotherElk

No. Encrypting “the phone” really only encrypts the data partition. Updates don’t affect the data partition.

Ah, okay, that makes sense!

@AnotherElk

Any kind of solution is currently unlikely … the custom TWRP 3.2.3 was a good shot, I’ve seen it decrypting Android 8 encryption a few times myself, but never with a “real” installation with Apps and stuff, only in “lab conditions” with a freshly installed OS … and never Android 9.

Thanks again for your detailed answer! I think I will just leave it that way. My main concern is to be able to install updates, and thanks to the root access I can store the files necessary for the update in /cache, as lklaus mentioned here.

Have a nice day!
