To cIVIc,
Have you tried your "10000%" wrong pinout
with any 'EXPENSIVE' T28s, the main wrong
point is the pin 11, it is the +3.5v from phone, you can measure it with a VOLT-METER. I have a service manual from Ericsson, I guarantee the first schematic is working (although it is not same as the Ericsson original design, at least it is 100000% working), I am selling this cable to the GSM market!!!

Hi,
I posted on the subject the first working pinout for the T28 ,i tested this before posting so you can be relaxed on what GSM-Starter Says.
Be carefull on what flashfile you use,even if you screw up,later with the correct flash you can allways recover your phone.

this pinout is 100% real but I think the t28 cable only can work with 3232 normal 232 chips can't work.if you have another good idea pls let me know it.
