Jumper TX error "Not a valid EEPROM"


#1

I guess is goofed and I updated something wrong on my Jumper T12. After trying to load a converted “OTX” file with OpenTX Companion, which the file was originally setup for a Taranis x9d, Opentx companion told me it would convert the file so I could use it on my Jumper T12. Things have gone bad. Now when I turn on the Jumper transmitter. I get the flash screen “Jumper TX” and I do get sound, but the screen goes black and nothing else happens. When I try to reload the EEPROM I get “Not a valid EEPROM.” Did I brick my transmitter or is there any thing that can be done?
