Currently stuck in Installing Update screen so don't know what to do...

Flashed successfully but when rebooting, Nexus 6P, is stuck in the "Installing Update" screen that is the first screen that appears during UBport installing.

This was eventually resolved by flashing repeatedly and trying with a different UBport image for the Nexus 6p.

The problem was either:

1. Flashed with the wrong image initially.
2. UBports installer during first boot of first flashing failed.
