i noticed on the n100 you have to start up msm and have it ready use "adb reboot edl" and quickly hit start in msm before your phone reboots

@rocket2nfinity Just thought I'd post my results for the N10 as well. In the past, I tried to repackage BE2026 Global firmware as BE2028, but I was not able to get the bootloader to unlock. Perhaps someone else is able to try something a bit different and get it to work, but just thought I'd share. Happy to share info as well. https://forums.ubports.com/post/93798

Personnellement, je n ai jamais réussi faire fonctionner waidroid (sur mon xperia X). Je mets ca sur le dos des capacités de la machine... Mais j essaye encore d installer UT sur oneplus6 (sans succes pour le moment - je trouve pas la version android d origine) pour utiliser confortablement les app libertine et essayer waydroid.
