New Matrix Infinity in a V3 - does not work with firmware 1.75 ?

[pstwo4u]

I installed the green dot Matrix Infinity (the new ones) in a V3.
This worked and could change the config settings.
PS2 backup games on DVD-R and DVD+R could be played.

Upgrading to 1.75 could only be done by holding the reset button until the blue light was seen.

When the upgrade finished, PS2 backup games on DVD-R and DVD+R could not be played.
Also I could not access the config menu.
Reinstallation of the 1.75 firmware, did not solve the problem.

So my conclusion was from that point, the 1.75 firmware is not compatible with V3's.
I only tested with 1 green dot MI chip.

Solution in that case, was to remove the chip, and install a new MI, and tell the owner not to upgrade to 1.75.

But, when I used the old chip in a V7, the chip did not work with the 1.75 firmware.
Reinstallation of the 1.75 firmware solved the issue.

In both cases, all the solder points were double checked.

So my conclusions could be:

1) The 1.75 firmware is not compatible with SCPH-30004 (PAL V3).
2) The 1.75 firmware could not be loaded on the MI (green dot) successfully (by whatever reason).

Has anyone seen this before ?

Also with V12/V13 I had to hold select button, in order to upgrade the green dot MI to 1.75.
Also the new MI is not working in a HK NTSC version SCPH-39006.

I think the v1.75 is a little buggy. I was having some odd problems as well. I installed a green dot Infinity on a v10 and tested a hdloader on it with no luck. It booted hdloader and put me to the game selection menu but once I run the game it doesn't load. Even though the games I loaded were working great on other consoles. I flashed back to v1.68 then to v1.75 again and it worked... I have no idea what happened.

I updated ti 1.75 in a pal v7 and now every time i first start I get the RSOD then its ok, went back to 1.68 and perfect again so my conclusion as tony said, buggy

i have installed in already a 20 greendot matrix infinity's in a v3 with out any problems also upgrading to 1.75 works without any problems

only problem i have seen with matrix infinity and v3 was with the v1.5 firmware
after that upgrade i had 2 v3's where the Bachip blow up
possible a coincident but it was very strange
