Hey,

Has anyone found anything about this yet?

I am working on the vibrant which is a galaxy S model in the USA.

So far I've been able to do the following:

Doing some searching around I found the CPU is a S5PC110 and i found a dev-board.

I took apart the SIM part. It did not reveal much.

What the person claims to have done.

HOW IT HAPPENED: Software-wise, just the JP1 downgrade to UVJE8. That's it.

Flip the PCB around so that the battery connector is on the right side.
Look at the very right (low) edge of the PCB.

Just above the hole (a bit to the left) you see a vertical row of five (rectangle) contacts.

From up to down:

AP_JTAG_DI
AP_JTAG_TMS
AP_JTAG_TCK
AP_JTAG_DO
AP_JTAG_EXTRST

A bit to the left there is a horizontal row of three (rectangle) contacts:

From left to right:

AP_JTAG_NTRST
GND
VCC_2.8V_PDA

A bit above the previous trio there is two (round) contacts:

From left to right:

AP_RXD
AP_TXD

I think the ones you are looking for are:

VCC_2.8V_PDA, GND, AP_RXD, AP_TXD
