2nd Devo 8S w/ white screen. help needed.

just got another 8S today for my friend. After flashing deviation 3.0, I got a white screen

I can still go into the firmware upgdate screen by pressing EXT / power on
I can see the filesystem in PC pressing ENT / power on

after disassembling the back cover, I find that the label is 1.0A while my old 8S is 0.9A......

The PCB version and date are the same. So I think the hardware is not different for the main PCB.

Does anyone have the same case with me??

You should flash a nightly, Devo 8S has a new screen. PB added a driver for it but it but after 3.0 was released. If you want I can build one for you.

EDIT:
Try the attached build.

EDIT2:
And read this thread for more info:
deviationtx.com/forum/6-general-discussi...tible-with-deviation

Bingo!

Many Thanks. My friend practiced 4 days of SIM and wish to play tomorrow, almost get him disappointed.
