Hey Guys,

I dont know if this will help you or not but only try on your own risk.

Mine one (Kingzon M42P) was just rebooting when connected to USB and was not getting detected.

I put a jumper from one voltage regulator ( form IN pin) to the VDD. Basically raising the core voltage and after that it stopped rebooting and windows can detect it.

My chip = AK1025
My VDD = original about 1.6 to 1.8 (max is 2V) - Now its 4.10 V

Its written that chip can get damaged if VDD is more than 2 V ( please read the datasheet of your MC)

Its running hot but i couldn't manage to work it out in any other way. I cannot find which component is faulty but when i measure the voltages on the chip, all are with in the limits. So i have no idea why its rebooting. May be battery is gone but still i couldnt find a reason why its rebooting with USB plugged in. But i still cannot flash my chip.

Try it if you really can really solder on SMD's.

Hope it works for you
