MPPS problems

Hello, can anyone help me with this one - I resoldered MPPS MCU with version V12.0.10.6 now the device is recognized as AMT Flash, but I can not make it work, as no drivers can be installed... Anyone?

instal v12 software
right click icon in device manager
click install driver and look in mpps program folder

Yes, that helped, but now the message no external voltage appeared. Anything? :|

D Don't be funny. It might be bad MPC solder?

.im sure if you have the mcu on and the drivers updated then your there...

download and take a look at my 2 photos of mpps pcb....

on picture "mpps 1" you see where voltage comes in to pcb and goes to the diode es1b then on picutre "mpps 2" you can see where the voltage goes out over one smd resistor 4702 and then goes to the mcu pin that is marked on picture "mpps 2"

check out with multimeter if you get voltage till the resistor 4702 and then check the solder of the mcu pin that reads the voltage.

check also this both resistors where the voltage goes trough on picture "mpps 2" if these are not good soldered you will get that error with voltage too.
