Jumper t8sg blank screen

Will try today
And post findings

Sorry for late

Everything is working with the 1/12/18 build

Thanks again

Need help here, I have upgrade my t8sg from quite old firmware t8sg-v5.0.0-e50fce3 to last nite build t8sg-v5.0.0-d21bf92, and blank screen occur, I can do nothing now, even old firmware e50fce3 was removed on download list, plase help. thanks.

I encountered the same situation.

Work as USBmode(USBdisk),so connect to PC.

Format that USBdisk by slow format and copy file system to disk from back up or firmware archive.

Turn on that again.

Have a good time!

Finally, I've found a old version firmware (deviation-t8sg-v5.0.0-8ab3744) to solve this blank screen, now my T8SG back to normal, however, still has problem to receive the RSSI info. from Frsky or FrskyX protocol, anyone can give me a suggestion? or its old firmware bugs?

Which file did you use to get your screen contrast working? I am now having this problem after flashing the control. I just got it and i manage to connect the control to a SIM and used it a bit but then the Pitch started to stay in -100 position although the stick was back to center i thought maybe the firmware needed updating now i have the controls not working and the screen with very low contrast.
