I bricked my remote controller gl300e while trying to return stock DJI go app, i tried to use fllashfire, found a firmware that i thought i could flash through FLashfire(cuz my dji assistant didn't recognize the RC).
So, generally remote works: i can fly, make shots/videos, but there is no any activity from the back android board > doesnt work the display. PC doesnt see the remote at all now.

The question: is there any chance to restore with a stock ROM/firmware the board that i bricked? As i think the question is addressed to android gurus cuz the board replaces the hardware of the phones which are the brains on other DJI remotes.

p.s. sorry for my english, i hope everybody understood me.

                        
        
                                                           

Hi there, thank you for reaching out and we're sorry to hear about the trouble. With regards to that, Unfortunately. We don't have an official tutorial on how to restore the firmware of the device and your only choice would be sending the unit into the facility. You may still wait for the best recommendation from other members, however. You can just reach out one of our support channels in order for them to guide you on how to send it in, just go to this link https://www.dji.com/support
Best Regards!

This is probably a long shot but some PC motherboards have a CMOS reset jumper on them to reset the BIOS back to factory.
