Problem with Thai PS2 and Matrix Infinity

[squarefan]

hi@all....

i have here a very unusual ps2.... it was bought in Thailand...

is a Japanese Model GH-022... BUT 220V and 50Hz... never seen this before....
I fitted a MI but the chip is not working.... connetions are OK (I know what I am doing)... but it seems to me, the bios cannot be patched. As if the chip is not there...

Chip is OK.. rechecked it with a another one!

maybe somebody else had a similar problem one time????

thx

I'm guessing that the model is SCPH-39006 NTSC/J aka v7. I've install MI on NTSC/J v9 with no problem only have to force flash the firmware to 1.5 as I got the bad batch using Homebrew firmware and you must connect the H point.

hi, i also installed the H wire.. but still no go!

i can acces the bios menu.. the disk will be recognized.. but then... over.. goes to browser and stays there.....

i checked the via (I and H) --> OK
remeasured the bios pints --> OK

even did the diode VCC fix... no go....

its just weird.....

Have you tried forcing upgrade to Infinity firmware, might be you also got the Homebrew chip instead of Infinity like I did before. Here is how to do it quoted from MI website.

Put Upgrade CD into PS2 and put PS2 into standby.
Press "reset button" and keep pressed until blue light turn ON (on V1-V11).
(For the V12 press reset button from standby for 2-3 seconds as there is no blue light).
Leave "reset button" and Upgrade CD will boot.
Follow on-screen instructions to complete the Upgrade procedures.

there actually are all sorts of different "breeds" of ps2 consoles for parts of asia including PAL/J consoles. The asian consoles still use the J designation for their consoles instead of using a seperate designation such as A or something. These consoles are quite the mutants however i havnt heard of any modern modchip not working on them.
