Recover from Bootloop in Ubuntu Phone If Flashed Non Stable Channel Ubuntu Touch Image


Today, I tried installing latest build of ubuntu touch from staging channel for Ubuntu Phone BQ Aquaris E5 HD Ubuntu edition. Even though the installation was quite smooth and successful, the phone got stuck up in bootloop. I kept it going for almost 30 minutes but it did not came out of it.

I tried to go to recovery parition by pressing POWER + VOLUME UP buttons. But it was not entering recovery. The only option I had was to enter fastboot mode. 

I could recover the phone with stable image available. I thought of sharing the procedure as this might be the case with many other users too. Below is what I tried from my Ubuntu desktop with Ubuntu Phone connected in fastboot mode,

sudo apt install ubuntu-device-flash

sudo apt-get install phablet-tools

fastboot erase system

fastboot erase userdata

fastboot erase cache

fastboot erase boot

fastboot format userdata

fastboot format cache

ubuntu-device-flash touch --channel ubuntu-touch/stable/bq-
aquaris.en --bootstrap --recovery-image /home/nikhil/Downloads/recovery-vegetahd.img

Please note that you will need to download recovery for BQ Aquaris E5 HD Ubuntu edition which needs to be supplied as argument during the flashing process as shown above. You can use below thread for downloading the recovery and why its required to download.
