I have modded a 39004 with Magic3.1 (original).
It had traces of one previous installation.
Ended the installation the console had many anomalies: it remains with the black screen, or very rarely the browser goes but when I open the tray and closing it does not work more, etc.
I have controlled all and all is ok. Then I have removed the chip and the ps2 has resumed to work correctly. The owner has confirmed that the same had said the first installer about these anomalies and I have thought that the ps2 has some problems.
I have had same experience today with other 39004 and now I do not think that I can find in three days 2 console brand-new with the same defect that never I had seen before.
I ask this ps2 can to be a v8? how can I recognize it?
