Hi Julia, Thanks for the answer. I didn't know for the update break, I'll be careful on the future and wait that some programs get a native Ubuntu Touch program - or forget them.
For the factory reset, I didn't do it via reboot "Power + Volume Up", but in the menu you have an icon for Parameters, and below the "Updates" row there is a command for doing a factory reset, one just for the launcher, the other for a complete reset. That's what I choose, confirmed the message for all datas that will be lost, the phone restarted, reset process began but E4.5 never started completely on Ubuntu, and since I get only a dark screen -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1569718 Title: Ubuntu Touch (BQ Aquaris 4.5) - Does not boot after "[Volume Up] + [Power]" factory reset To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1569718/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
