ALL JIG VALUES here!

3rd June 2011, 01:12 AM |#1  
I've found the datasheet for the FSA9280 online today. So, now I can post about it.
http://www.mediafire.com/?d4e21efhuktctcb

This datasheet is valid for all GalaxyS and GalaxySII devices.

Ok... So, first off.. A JIG is the line on the FSA chip which leads to the processor. The JIG line is usually high. Any resistor which makes that line go LOW is a JIG resistor.
These are the JIG values. They are used on the usb port between pins 4(X or ID) and pin 5(ground).


Here are the rest:

Ok, so obviously the most interesting is the the factory mode boot on UART. Good stuff.

Didn't get much, but would be very happy if this helps in the development of devices/JIGs that would help in unbricking the dead devices. And this what is intended of all this, as I get it.

There's 32 bits. This is all resistor values.. All 5 bits are taken. 32 choices.

I graphed it out.

I just realized I missed both short and opened values... They set bits. Everything is taken. There cannot be any more. I updated the picture as well

I see there is an audio remote thing. Would it be possible to make an app in visual basic and use my sound card and a aux cable in the phone 3.5mm jack and send that into my phone?

Edit: there is also alot of commands on there with diffrent Ohms what do those commands do?

Great finding Adam!

I would like to prepare a rescue set for the SGS-2, from a JIG and a microSD. If I read your table correctly, the 301kOhm USB JIG forces the device to boot in "Factory mode 1".

Is there a description somewhere, what these modes mean? (my goal is to convince the device to look for the bootloader on the microSD)
