Hi, I just download the latest Raspbian (2018-06-27) and flashed to a 32 GB SD on PI3B+. It starts booting but after a few seconds (and a lot of kernel messages) it gets stuck to the rainbow screen and reboots.
I tried replacing the SD to no avail. Now, next, it's checking the power adapter.l when I get it.
In the meantime, is there anything else I can check? Maybe someone ran into the same issues and know how to solve it.
Thanks a lot.
