I have a few G90s and TBP12s. I have managed to update all of them to 2.0 (G90s and the transmitters) with my X75 receiver unit. However, there is one TBP12 that will not go into "Loader On" mode. When I power the unit on with the select button pressed, it scrolls the firmware as 1.02 which is the listed minimum version to be able to update to 2.0. However, no amount of holding the value button, powering it off, and then pressing the select button 8 times gets it to go into loader mode. Is it possible there are some versions of 1.02 that do not support this mode? Really can't figure it out. I know the buttons can be hard to press but I've double checked that the buttons work fine during normal operation. I have even put a few of the 2.0 receivers into loader mode just to verify I'm still doing it correctly and they all easily flip to that mode.
Any other ideas at this point?
