Format your phone, you have to type 'yes' in twrp.I just bought the 5T and testing this rom since i like the devs work on the 3T. There is a lot of weird issues on the 5T though. I am not able to disable encryption with either fastboot format userdata or format data from recovery. Then there is encryption in TWRP. I have only found one recovery that will pass the pattern (bluespark). Anyone that have some ideas about this? I would prefer an unencrypted device.
When it comes to rom, if i try to login to the phone with fingerprint it just stops at the background image saying "Mobile is starting" if I choose with pattern, it will work instead. Hard to get a log about this.
When it comes to features - Is it possible to kill apps with longpress on back button? Is it possible to add a function somewhere so i can get menu by short press on the right nav button and recents when i long press?
Now move your files over. This is where you need to pay attention. Flash the ROM, gapps, kernel (optional), magisk (optional), then no-verity. Always flash no-verity last whenever you flash a new ROM. This will keep you decrypted. There's a v4 of this zip, but I don't have it.
If someone has the v4 zip, please post it.
Also, your new 5T. Did you flash the latest official zip, 9.0.6? If you don't have the right firmware, then the ROM will not operate correctly. Make sure you flash the correct firmware release.
