@kophamerla I think it is just another step, at least I did not have to reinstall the binaries afterwards and it works just fine now. Good luck!

@herkovb I tried that too, did not work though. I managed to do it by now, it worked just fine after installing TWRP and erasing the above mentioned data

@Andreas-Pokorny Hi Andreas, I just tried to install Ubuntu touch as you described. It worked fine until I started with the Installer. Somehow my phone goes into a loop of booting as soon as the Installer is downloading the OS and preparing the image. It then asks me to reconnect my phone and try again. Any help is appreciated
