hello this is wrong it think. i managed to install twrp and root my htc d820u while on kitkat. but when i tried to install on lollipop the twrp will just give me a black screen. concerning root it i could not test because the phone reboots to the twrp black screen..
the twrp is responding though, i think it's an incompatibility problem with lollipop.
