Hello out there,

yesterday I've read about flashing my old bq aquaris 4.5 ubuntu edition phone on twitter. But - sadly - the ubports installer on windows 10 does not identify my phone. It stops working on the "Please Reboot to bootloader"

There are two modes on the phone:
The First one is a menue with a blue font to test the hardware (power on + vol down I think)
the other mode is "select a boot mode" (recovery / fastboot / normal) (power on + vol up)

Are there any hidden hints to flash? Has anyone a tip for me?
