Hice la misma pregunta en el hilo oficial del Slayer en Xbox-scene y esto fue lo que me contestaron:
" I am sorry that I wont help with TSOP flashing as it is very easy to kill an xbox in the process, How do I know this. Well during the Beta testing of the installer there was a bad Bios file it was a D6 bios untouched by us and when I flashed it to the 1.3 256K TSOP it killed the xbox. This xbox I purchased just for the testing of the installer to confirm the bios we included in the installer worked with both TSOP and mod chip.
So for this reason we will not offer help with TSOP flashing, I will say that the bad Bios was removed from the installer and only those that were tested and functioned properly were left in the installer. "
Hay muchos riesgos en estos modelos de dañar la Xbox si hacemos flash al TSOP ,,,o sea no aconsejo eso...
Saludos.
