Hi, did you get an answer from BQ support ? I have the same issue.
Some weeks ago, I tried to install Prey on Ubuntu Touch BQ Aquaris E4.5 with this method : http://wayneward.co.uk/ubuntu-touch/prey-on-ubuntu-touch/ It failed, but after that, even if I can't affirm it's correlated, updates apps were working but not OS : I got the notifications of OTA 33 available, if I ran the update, phone reboot, began installation, then continued the process, started... and I was still on the current version, unable to update to the last system. So I decided to save my contacts + SMS / Calls, and did a factory reset, directly from the GUI Parameters menu. Phone restarted, stayed long minutes / hours on black screen without anything written. Sometimes I make a long press on "Start" button, I well see the BQ logo on the white screen, like Antoine Denis described, but just after the complete empty black screen comes again, and nothing else... I'm in big trouble now, as I used it with 2 lines, a professional one included. Any help on this, something to do to get logs ?
