GT3C Failure at flash v 0.6.1 Swim Lockout

[bender615]

I attempted to flash v 0.6.1 to a new GT3C and it locked the transmitter. It flashed properly but it would freeze every time I turned it on. It would not initially let me even finish calibration. Also, it will not let me connect through the st-link mini, it give an error about the connection and to reset the application. My soldering is fine, no problems there. I spent a week troubleshooting it, it will not program. I finally was able to get it to work, but it was a lot of trial and error. I finally put the battery back in, turned it on, it froze. So with it open I connected the GND and RST pins - this reset the transmitter. I did this repeatedly until I could complete the calibration. Once I was able to complete the calibration, specifically the battery level (4.2v on the fully charged lipo that came with the Tx). Now that the battery is calibrated it seems to finally be stable. Is there any way to write into the firmware the battery level at 4.2v? Perhaps that would solve the failure issue.
