Installing current trunk esults in bootloop.
First I tried to install it over stock firmware with recovery/tftp but it was stuck in bootloop.
Then I reinstalled 19.07.02 via recovery/tftp - which worked fine.
After that, I tried to install trunk via recovery/tftp, but it also gave bootloop.
The symptoms looks like the ones mentioned below. The problem was fixed, and maybee the same solution is missing in trunk
