are you able to put the PHM into the original state and test it (with GSM modem and VOC SIM)?
if nothings change then the PHM (main board) is probably dead.
but if VOC is enabled then it is possible that some unexpected command has came to Bluetooth module. in this situation the module sends an error message (unknown command). and it (maybe) can cause that PHM is now switched into non-standard mode. and it is possible that after you put the GSM modem back and you turn it on that it starts operate again.
but it is just a speculation. it looks that the PHM is probably dead.
