Hi I am seeking help because when I was replacing the battery in the mpu6 since it had died for not being used for many months I accidently erased the software on the mpu6 screen now when i turn it on all there is is "self test" "bootloader" and "erase" how can i get the firmware back onto the machine with a usb or something else?
its a Rainbow Riches : Reels Of Gold game with 5 reels and in horizon + cabinet
thanks a bunch in advance!
