So I was going to root this (previsouly healthy) BQ A4.5. Unlocked the bootloader and flashed TWRP from here:
$ fastboot oem unlock (bootloader) Start unlock flow OKAY [ 32.954s] Finished. Total time: 32.960s $ fastboot flash recovery downloads/twrp-3.3.1-0-dendeone.img target reported max download size of 134217728 bytes Sending 'recovery' (11342 KB)... OKAY [ 0.378s] Writing 'recovery'... OKAY [ 0.335s] Finished. Total time: 0.727s $ fastboot reboot bootloader rebooting into bootloader OKAY [ 0.003s] Finished. Total time: 0.058s $ fastboot reboot Rebooting... Finished. Total time: 0.058s
The first reboot to bootloader didn’t do anything. Now it’s on a bootloop which states:
Orange State Your device has been unlocked and can't be trusted Your device will boot in 5 seconds
Pressing Volume Up + PowerOn used to work for recovery (that’s how I got into fastboot mode). Now, pressing Volume Up/Down/Up+Down + PowerOn doesn’t do anything, fastboot stands indefinitely
< waiting for any device >, and adb always responds with
error: no devices/emulators found regardless of when it’s run. If I press Volume Up+Down it turns off. Plugging in USB it turns on. Nothing else seems to respond.

The disconnect happens before the bq logo appears.
Trash bin time?
