I’m trying to install the TWRP img files (here https://dl.twrp.me/h815/) and none of them seem to work. after adb’ing to recovery, i only get an android icon with a " ! " on it. i’ve been installing TWRPs with my other phones and they work fine except for my H815
i’m on v20a, bootloader is unlocked, marshmallow. i’m using h815, vd2 (vodafone germany)
is there something wrong that i’m doing?
