Fairphone 2 TWRP 3.3.0-0/3.3.1-0 can't decrypt Android 7/8/9 encryption

What does “can’t decrypt” mean in your case? Does it not accept the correct decryption pattern oder does it not even show the pattern request to decrypt/mount data?

It doesn’t ask for the password/pattern.
Message on the terminal output is:

“Could not mount /data and unable to find crypto footer.”

I’m running a system with /e/ (version 0.5-201905018716, resp. Android 7.1.2). Decryption in TWRP 3.2.3-0 works perfectly, but when using TWRP 3.3.0-0 it even doesn’t ask for decryption password/mount data partition.

Oh, ok. I hadn’t checked with my LineageOS 14.1-encrypted data partition, but I did now, and I can confirm your finding. It’s the same as with the newer encryption.

@z3ntu: TWRP 3.3.0-0 also doesn’t seem to be able to decrypt Android 7 encryption. So regarding encryption, the Fairphone 2 TWRP 3.3.0-0 seems broken in general.
