New problem, that i think is related to the modchip:
When the Xbox is arrived, i realise that the modchip was not installed in the xbox, but i had to solder it (there have been a misunderstanding between me and the seller)
However, when i took the modchip, I've seen that the part that have to be sold to the LPC was completely gone (probably the pads got damaged when the chip was desoldered)
However, the chip was a "gift" by the seller, so i didn't get angry so much...however, I thought that this problem might be solved soldering every point of the LPC (looking to the scheme, obviously) and using the pad along the circuit of every point. I've done it, but when i turned on the xbox, the chip didn't start...I've tried to turn on and off the xbox many times, pressing the power button and the eject button for 1 second and so on, but nothing happened.
However the xbox loaded the ms dashboard without problem (it ask me to set the date). (I tried also to sold D0 to ground, to make modchip always on, but nothing happen..the situation was the same)
After some minutes, however, the problem: when i turned on the xbox, it turned on and turned off for three times, then it showed me the frag (flashing red and green light) and black screen.
So I immediatly turned off the xbox. The problem was present every time I turned on the xbox. So i think that could be the modchip the problem (even if I checked every soldering). I desoldered the modchip and, indeed, the xbox started correctly again. So i tried to turn on and off many times, and it worked.
Then, I leave it on for some minute (to see if something was ok), but after, i think, 10-15 minute, the xbox got the black screen with the yellow flashing light. I've read that this could be a problem of overheating (and probably it was, because i hadn't close the case)....however after some times, i tried to turn on the xbox again...but here the bad surprise: Frag. The xbox, as before, turn on and off for three times and then show the red/green led flashing... What is happened?
(Before installing the modchip, I've changed the EEPROM phisically from the motherboard, because the original hard drive was broken, so I've taken a drive from another xbox and to resolve the problem of the key i swapped the EEPROM...however, after this operation the Xbox turn on without problem so i don't think that this can be the reason).
EDIT: Another think: when i soldered the D0 point to ground, I've not soldered the one on the modchip to ground, but the on the motherboard...I don't think if it could be the reason (sincerely i remembered that the point to sold to the ground was the one on the motherboard), but however after i remove it (alongside with the modchip) the xbox worked, as i said before, so i don't think that this is the problem.
