Modbo v4 - GH-041-04 - RSOD

[D-BlooD]

Hi all i started this thread some other place but since i wasnt getting any replys there i thought I try here. Its total of 3 posts that you can read under here.

I have searched and tried about anything i can think of to get this PSTwo (v14) working with my modbo modchip but no luck.

The problem I am having is that the machine will originals but no backups of any kind. It will only give me a RSOD (Red Screen Of Death).

Wires installed after the following diagram http://www.brisbane-mods-brisbane-mo...scph-75002.htm

Tried with and with out H wire (this is a PAL machine so I shouldn't have to use H)

YIGBHA is checked against the CXD chip diagram by Team Matrix http://www.infinitymod.com/matrix/fi...XAlternate.JPG I used the multimeter from the soldier points on the modchip and to the pins on the CXD.

I also soldiered the SX to the CXD chip.

Matrix Logo shows at startup.

I am able to go into the config meny without any problems.

I have tried replacing the modchip with a new one and redid the wiring twice and no change.

I have also checked the mother board for splashes and found none.

Laser is also replaced and that changed nothing.

have been doing some more research and I have read that there are installers having the same problem and that the solution is to downgrade the firmware to v1.93/v1.91.

Have anyone here tried downgrading a modbo v4.0 with 1.99 firmware ? Is possible at all? If so can the Matrix Infinity firmware be used or do modbo's have their own firmwares?

Recovery mode works so I am able to boot the matrix firmware on CD-R just fine, also the same with toxic firmware.

I tried downgrading just to see what happens to the official 1.93, 1.88, 1.82 and 1.75. All of them load up fine but when I press the Start button to "upgrade" nothing happens.

Please come with suggestions

Thanks..

what type of wire do you use to install the mod chip

I don't think you can upgrade firmware on the modbo chips. At least I couldn't.
Which modbo 4.0 have you got ? has it got an F pad on it ? If so that is the so called "new" modbo4.0. I tried these a while back and had trouble. So I sent them all back and returned to using the "old" modbo 4.0 (no F pad) which I have had very little trouble with over the years. My advice would be to steer clear of the "new" ones. Where did you buy them ?
