Sony CMH-333 Cellular Telephone There seem to be two types of cmh-333's out there, with two different NAM programming sequences. One is the marsbar.txt (old method),so called because I had it before the cmh-333.txt (new one). To change the ESN, there is a program by The Cheese Factory that requires a cable to be built. Here's a diagram of the cable required: The end of the cable that connects the phone is a bit tricky. I myself have a load of little PCBs that slot into the correct part of the phone and I solder the wires onto this every time I make a cable up. If you know me personally I can sort you out with an end, if not they're easy enough to make up on a PCB machine, and if you're _really_ stupid you can buy the cables at next to nothing prices out of Exchange & Mart or something these days. _________________ _________________ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | \| | | | | | | | | | | | | | | | | | | | | | |_________ | _ | _| |_______ | ___ | _| | | | | | | | | | | | | | | | | [R] | | | | | | | | | | | [19] [20] [11] [8] Value of Resistor R = 10k Numbers in square brackets represent Pin number on D-Plug (-> Printer Port) The large squares represent the top and underside of the phone end of the cable. You should have a small PCB with 7 contacts at the end (represented by | in the diagram above). | As you can see I was never any good at ASCII diagrams... That should set you on your way. =(*)=Pulse=(*)=
