Reconnect it to the car to make sure the bootloader actually flew out or not. The thing about NBT headunits is that when they're in flash mode, they only need power to go back to the blue screen.
If you do not see anymore your nbt2 in esys and bltd was 100% and then fail, it means that your bootloader fell out. I have done flash with gps retrofit many times but it is better to turn off gps in adjust block and then do flash. Now you need usb serial, so If the bootloader loads using usb serial, there is a good chance you will write it again, using right commends.
