@advocatux white screen of blue circle doom after 5 min. Looks like OPO stuffed up

Hi all,
I don't understand how to re-install another version... I don't think developer mode is enabled on my machine and I can't enable it any more due to the white screen of death we are seeing... so I can't see the solution?
Thanks, Marc

@truscellino have just put my OPO back to 428 on the dev channel following the instructions given above by @advocatux using ubuntu-device-flash. You need adb on your pc/laptop and can install ubuntu-device -flash with sudo apt install ubuntu-device-flash. Make sure you have the correct device code name (bacon in my case) and update version that was ok for your device (428 for OPO). So connect your device to pc/laptop start adb then for me it was
ubuntu-device-flash --server=https://system-image.ubports.com touch --device=bacon --channel=ubports-touch/16.04/devel --revision=428
hit enter and let it run. Good luck. Only up now as daft enough to try an update this late at night. Let us know how you get on back tomorrow.

OK sorry I got there finally... back in 16.04/rc now. My main problem was not to succeed in rebooting into recovery mode...
Thank you for quick response, very much appreciated!

Thanks to @advocatux I could flash the old image to my Moto G2 Titan. The command is
ubuntu-device-flash --verbose --server=https://system-image.ubports.com touch --device=titan --channel=16.04/community/walid/devel --revision=121
I had success and my device is fine again.

@advocatux Welcome back 431 works on my OPO!

@lakotaubp kudos!

BTW I see @Nikfrager has added the verbose parameter. Good idea.

If anyone want to know about all the ubuntu-device-flash parameters available, see
