Describe the bug Transmit is disabled after flashing the radio with NUNU v20.5. Always I press PTT only message appears "VOLT HIGH - TX DISABLE".

Details:

Firmware version: NUNU v.20.5
others: F LOCK = DEFAULT + 137-174 400-470 (doesn't mather what is set, behavior is the same as described)

Radio is classic UV-K5 with 1600 mAh battery bought on Banggood. Audio level is very low outside of FM radio or beep tone from keyboard.

It is not a bug. Voltage is too high. You might want to read Wiki on how to calibrate the battery or use a different battery.
