Hi,
I was trying to flash UT in my fairphone with Ubports. It didn't work and now I want to use another OS instead. However, when I start my Fairphone OS, it now says powered by Ubuntu. And the TWRP necessary to flash the other OS doesn't work. So my question is: how to get rid of Ubports elements left in the bootloader?
I tried Factory reset but it doesn't change boot.
Thanks!
