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 Touch seeded packages, which is subscribed to unity-system-compositor in Ubuntu. https://bugs.launchpad.net/bugs/1569718 Title: Ubuntu Touch (BQ Aquaris 4.5) - Does not boot after "[Volume Up] + [Power]" factory reset Status in Canonical System Image: Incomplete Status in Mir: Invalid Status in mir package in Ubuntu: Invalid Status in qtmir package in Ubuntu: Invalid Status in ubuntu-system-settings package in Ubuntu: Invalid Status in unity-system-compositor package in Ubuntu: Invalid Status in unity8 package in Ubuntu: Invalid Bug description: Today, I tried to factory reset my BQ Aquaris 4.5 Ubuntu Touch Edition with the [Volume Up] + [Power] method but since then, the phone won't boot.
