@keneda I totally agree, i would reboot my phone multiple times a day to gaze a tux. ... just saying.

It seems to be the nature of the beast. the annoying boot loader screen isn't a huge deal, but it does beg the question, how secure is the OS? Does this mean google has a back door?

@rosenfeldpj i got the same error, however i changed pc's and boom it installed no problem. are you using a windows or linux pc to try and flash. for the record the machine that was failing was a desktop running ubuntu 21.04, and the machine that worked was a laptop running 21.04. Also try using an older version of the installer.
