Hi guys, I have just received my first Gameshell yesterday and I have managed to assemble it today.
I am working as a Hardware Engineer. I am pretty sure I have connected all wires correctly (especially the Display FPC). I have applied an USB meter and the board current consumption is looking normal as it is not turning ON.
The Gameshell is unavailable to UP no matter what I have done as shown below:
Double check the orientation of FPC
Measure battery voltage level (3.9xx - 4V)
Disconnect all modules except mainboard and display board
Unplug and replug SD card
Re-flash SD card (original A) with New GameShell OS Image v0.6 gamma OS image
Try connect a micro HDMI - HDMI to my desktop monitor
Re-flash another SD (B) with Custom D.E.O.T. V2.0+ OS image
Try connect a micro HDMI - HDMI again to my desktop monitor
There is NO display output signal can be found
Confirm that the ON/OFF switch is workable (two pins are shorted when pressed)
Confirm that the reset switch is workable (two pins are shorted when pressed)
None of these above approaches can bring my Gameshell alive.
I suspect my mainboard and display board are defected.
Please share your opinion if you have solved this issue before, thanks a lot.
There is an orange color LED when I charge the battery via mainboard, no other LED flashes in any circumstances when I disassemble the battery from the mainboard. No display output signal even I plugged a micro HDMI to my desktop monitor.
Try using a different tool to flash your SD image. The Gameshell is kinda picky and if the image isnt exactly right it wont boot. If it doesn’t boot fully you wont get any screen output, the blinking green light, or any other obvious signs of life.
With that said, this could be a bad mainboard. I had this same exact issue with my Gameshell. I contacted support via email and they sent a new one after some quick troubleshooting. Make sure you include all the info you have here if you end up needing to contact them.
