Step 3: Solder points the points explained in Step2.

Step 4:Install Matrix, "Before I powered up the Xbox I switched the chip to MODE 3 (this is important) and held the end of the T1 wire on the screw (which I think is just Ground and you can use the Xbox Silver housing and it will still work)" pasted from Ravencry's post (This could not be done without Ravencry,THNX!!)

Step 5: "powered up the Xbox and the led on the chip turned from green to red stating that the chip was now in the original bios. I let go of the T1 wire (as stated in the pics)

After that The evox dash booted (I don't know how they did it but it works)
I went to the Settings tab and selected Flash BIOS

I selected the EvoX 2.5 Color Blue 1 megabyte bios file and it stated that it found the ID of the TSOP!

I Clicked 'Y' and it Began to erase the TSOP and after that the Flashing process started!!! You should have seen me jumping with joy!

I now have an Xbox with a flashed TSOP and a Matrix chip

What now?

The options are so many! here is what I am going to do next
Use the tutorial on how to have multiple bios files on the TSOP (here) and have a setup like this

2x 256k bioses (evox 2.5 and original 4034)
1x 512k bios (devkit or any other 512k bios)
1x 256k bios on the Matrix (playing with evox to flash it with anything new)

I never doubted the Evox skills and the capabilities of the MatriX chip and this makes it even better now that more features are out for it!

Thank you EVOX and Xodus Team for your effort" also quoted from Ravencry :)
