Member: 28095 Status: Offline Thanks Meter: 0 | 7250i Sim card reader contacts broken HOW to fix???? Very bad i know, but i would like to try and fix it, does any one know where the pads lead to ? As i could solder some thin wire from that point to the sim card reader pads and solder them to the legs of the reader, hence gettin it to work (hopefully) Any help would be greatly appreciated Regards NaaN |
