[Q] TWRP won't install on rooted device
I have xperia s (st25a) phone with android 4.0.4.
I already have rooted it (SU installed) and bootloader unlocked. Fastboot reports the correct version "5".
However, when I try to install TWRP, it gives the following error:
>fastboot.exe flash boot stock-6.1.A.0.452-twrp-184.108.40.206.elf
sending 'boot' (8124 KB)...
FAILED (remote: The Device must be rooted first)
Why does TWRP think it's not rooted? I have setup SU to grant every root request too!
Another issue - when I try to enter recovery with stock image, my phone gets stuck on boot with Sony logo and I have to remove battery to shut it down. Any ideas why wouldn't stock recovery work?
Thanks much for your help!
