MI on V4 - Can`t Flash - Programming Failed

[clemente]

Hi Folks..

I mounted an MI (Green Dot) in a V4. Before i had an Magic3 - Working Fine.

After soldering i test the Wiring with an Multim. From MI to the pins of the Chips. Everything looked good.

Then i boot with FW 1.91 Disc - But the only thing happens was an White-Screen for a short time and then a Black Screen.

Then i boot again without Mem-Card in the socket.

After a short Time appears the Matrix-Flash Screen. When i hit "x" to Programm, the Programmingmode starts, but then comes the Message
"Programming failed"

I`m Sure that the chip is no Clone.

Somebody told me, that the problem is the Laser. Maybe too old and can`t read the FW_Disc correctly....

Any other Idea`s ???

Please help me..... THX

try this m8:

install a previous firmware first, like 1.88 or so, or even older, then gradually upgrade to 1.91

maybe it will help

probly a poor install. post a pic

I tried out other FW. Down to 1.75.

Always the same.....

My Digi is not at home - post an picture on Friday...

I checked the wiring with the Multi.

From Matrix-Chip to the Pins of the Chips on the PS2 Board. Not only to the Soldering-Points. Everything`s ok !!!! ????

The only thing - maybe a Problem ????? - i wired Q,T,U,V,R,W on the

Soldering points of my magic3 installation (marked Red), because they are directly connected to the points of the MI wiring diagram on the chip.I checked this with the multi....


I read in an other Thread about a GND-Wire which is too long....

Can this a reason be ????

THX

[broodje]

could be, but the chip should not work at all if the GND or + wire is too long i think.

So....

i cut the GND and 3.3 to a short lenght. (About 3cm)

Now, following happens:


1. If i press the power button for about 4 Seconds, the Console boots, an load the FW Update, but asks wether i would Programm FW 1.82.

(But it`s an FW 1.91 Disc. With this Disc i updated the PS2 from a friend up to 1.91 it works... )

If i press "X" the Programming starts and Prog the FW. It reaches 100% and say Programming complete....

But if i boot the PS2 again it shows no Matrix-Logo, and when i press Triangle+Circle for Menu, it doesn`t show the menu....

2. If i press the power button short, the console boots, the Disc spin for an short time - but the Screen is black.....

What`s going on here....

[clemente]

So...... tried out another thing:

I removed GND + 3.3V to switch the MI off.

Hmmm, the console only boots if i press the PW-Button for about 4 Sec.

If i press him shorter, the PS2 Fan go on, the Disc spin around and the Screen will be black....

Damn... Maybe there is an "short" Problem...

[mabcom]

check for a short between V and R
this results in a behavior you descripe

[clemente]

Ok.... Checked this with the Multi:

No short between V and R. (resistance >20MOhm)

I checked every Pin at the Bios-Chip... Against all other No short.

Holy Crap....

F*** o**!!!!

I ripped of the Chip out of the PS2 complete incl. Wiring.

Now the PS2 works fine.... (Nothing broken )

I put the Chip in an PS2 of my friend and flashed it to 1.91. So the Chip is ok.

I install it at noon today again... We`ll see what happen

I`ll Post the result
