Flash Tsop With X2 (and Others) 12c508 Code, here's what we've thrown together so far Options

[Ubergeek]

Not had any time at all to work on this - so we knocked this together last night to give budding coders something to have a crack at

pls no questions - if you now what you are doing all your answers will be on this page

This hasn't really been tested and may need adjusting - but it basically controls d0 and a15 similar to the matrix for flashing your tsop

TBH i dont know why this hasnt been released to the scene before now as the code is really really simple

CODE

some info that this code was based on (found on xboxhacker.net)

Programming the Onboard TSOP using a X2PRO or X2LITE.
This can be done and has been done on 1.0 boxes.

1) Connect TSOP Write lines (See matrix instructions)
2) Ground A15 (T1 on the matrix instructions)
3) Program X2Pro with EvoxMatrixTSOP bios
4) Turn power on and after 1/2 second turn DIP switch 4 off
5) Wait for EvolutionX to come up
6) Remove A15 Ground
7) Use EvolutionX to Flash a 1 meg bios to TSOP

Make sure your Evox xbe is named and placed somewhere that the EvoxMatrixTSOP bios can find it. I used a CD-RW with Slayer's 2.0 disk and Flashed 4974 onto the TSOP.

Look at the TSOP Flash Matrix Instructions floating around for pin locations etc.

This works with both the PRO and LITE but ONLY on 1.0 boxes until a EvoxMatrixTSOP bios is released for 1.1.

BTW, After you remove the A15 ground but before you flash the TSOP, if you use EvolutionX to backup your Box, you will have a copy of the orignal bios from your box. But you must do steps 1-6 first before you do the backup or you will just backup the X2.

yeah there is look at PhoenixBiosLoader 1.3 it allows you to load the bios trough the ram works great still a few probs with it but it wil be the next best thing to the 007 and soldering the points on the mobo
