I checked the solder points on the mod chip... they are all fine 100% sure about it... I scrached the protective paint further down the PCB on the same circuit and checked if currect can pass from the mod chip to the solder points with a multimeter and all of the points were fine.

i got no idea what to do now... is there anyone who can confirm/deny
