I have successfully installed TWRP 3.1.1 on my HTC Desire 510. I have rooted the phone with a modified ROM (so I think). But supersu keeps complaining: "Die SU-Binary muss aktualisiert werden. Fortfahren?" (i.e. super-su binary must be updated. continue?) If I continue, I can choose between "normal" installation and "using TWRP/CWM" for installation. Neither works.
- "Normal installation" yields "SU update unsuccessful" and leaves me a reboot or a link to some tutorials.
- "Installation using
TWRMTWRP manages to boot directly into TWRMTWRP (yeah!), but does not change anything. super-SU comes up with the same message after reboot.
- I also downloaded the last super-SU zip and installed it from
TWRMTWRP, but with the same outcome.
I have some suspicions.
- the phone might not be rooted properly? I unlocked its bootloader according to the HTC standard process (fastboot and token generation on HTC's website). This at least allowed me to install
TWRMTWRP and a modified ROM. I checked root access with two different root checkers and they told me, my phone was properly rooted
- supersu is somehow broken?
