  1. Hi there!

    I’ve been trying to root my HTC U11 using TWRP + SuperSU/Magisk with no success. I’ve follwed every tutos I found, but still can’t root my phone. Actually I’ve been able to install TWRP and it works flawless, but not the “root” itself.
    Can you help me in this process giving me a path or a link to follow?
    Have you ever seen this issue before somerwhere else or someone who has passed through it?

    Thanks in advance,

    Adriano (from Brazil)

    1. Hi Adriano. After installing TWRP, did you flash the latest Magisk ZIP file via it to root? Avoid using SuperSU as it has been discontinued and doesn’t support any new Android versions.

      Normally, that’s the most straightforward way to root a lot of OEM phones.
