DMS4 Läserbara Orginal

[Troca]

Hej köpte ett DMS4 chipp installerade det i min Ps2:a SPCH 50004 det är väll en v9:a hur som helst jag kan disabla chippet genom att hålla fyrkant intryckt vid startup + att orginal spel tar den men då jag ska flasha chippet men en Toxic BIos så vill den inte Läsa skivan =/ har provat en MASSA skivor som funkar Klockrent på Polarens ps2:a någon som vet vad det kan vara för fel ?

DMS forum users may have noticed a number of almost identical sounding problem reports regarding DMS4. We felt that this was highly unlikely and so began the task of unravelling the mystery. However unlikely claims are, the DMS team takes any such reports very seriously, and we have asked several forum members to forward their problematic consoles to us for testing and further investigations. Our findings were that it was their installations which had various problems, such as:

- CDVD OE wire (O) connected to wrong point on DMS4
- Broken wire to BIOS
- CDVD points shorted to ground
- Eject wire (C) trapped and broken under metal shielding
- Badly burnt flash upgrade CD's

It is also interesting to note that many of the forum members reporting problems were brand new users with 1 post, and many of them shared the SAME IP ADDRESS - now, I wonder what's going on here?

The DMS4 lite and pro were extensively tested on 24 different console versions before release so we can therefore be certain that the DMS4 mods are relatively bug free and are very high quality products. For more detailed information regarding our investigations please see the ongoing forum thread HERE.

We would like to remind users to take greater care with their installation, ensuring that the wires are soldered cleanly to each point and without shorts. Furthermore users should ensure that their solder connections are intact, by checking each point on the modchip and the motherboard with a multi-meter for continuity. If you do not have the skills required to do the installation, then please ask someone who has to do it for you. Otherwise you may be left with a broken console and possibly damage the modchip too.

The DMS Team take customer service seriously, we take every conceivable precaution to ensure that you get a quality product. We are sure that it's this dedication to quality which has driven our sales this season.

Users can be sure that we'll continue the pursuit of high standards and innovation."

Post subject: DMS investigates reported problems with DMS4 solder chips
Updated: 10/12/04

As many of you are probably aware, during the few weeks after the release of the DMS4 series modchips we had numerous reports via the forums from people having problems with their new modchip. The most common problems were 1) black screen on boot, and 2) "red screen of death" while attempting to boot homebrew software via the factory default flash such as the ToxicBIOS upgrade disc. We have been in contact with several forum members and have arranged for them to send us their problematic consoles so we can investigate. Well, we have now received about half of the consoles which we've arranged to have sent to us and in each case have found a cause for the problems as well as a solution. So far in all but 1 case the problems have been due to errors with the installation. Below I have listed some of the problems accompanied by the corresponding solution. I'll update this thread as more of the consoles arrive in our hands.

Symptom: RSOD while booting upgrade disc
Problem: Installation with modchip was fine, in this case the problem was actually the burnt upgrade CD-R. The upgrade image was not written correctly resulting in corrupt data on the CD-R.
Solution: Make sure you use up-to-date burning software, which knows how to handle BIN/CUE images (2352bytes/sector). We recommend Nero. This is a common problem, please make sure your burning software can handle the cd images properly!

Symptom: RSOD while booting upgrade disc
Problem: Wires were not secured properly so when the console was put back together the C wire (for the EJECT signal) was damaged. This means the modchip will never have known that a new disc was put in, so when the upgrade CD-R was inserted re-authentication would not have taken places resulting in a RSOD.
Solution: We replaced the C wire and secured all the wires properly before re-assembling the console. Everything worked perfectly after this.

Symptom: RSOD while booting upgrade disc
Problem: The person who originally installed the modchip had mixed up the O and Q points on the chip, connecting O from the PS2 to Q on the chip.
Solution: Once we connected the O wire to the correct point on the modchip it worked perfectly. PLEASE people, make sure you don't mix these two up. It might be a bit confusing since the O and Q look similar - O is next to A, Q is in between P and R.

Symptom: Black screen on every bood.
Problem: Something went wrong when the user tried to flash ToxicBIOS and the flash content became corrupt. Normally the checksum routines would detect this and display a red screen however this time it wasnt the case, probably due to very corrupt content.
Solution: We booted the console into recovery mode by the "hit reset 3 times from standby" method. This results in the backup flash bank (which is read-only) being booted instead of the standard flash bank. Once the console booted using the backup bank, we inserted the ToxicBIOS upgrade disc which then booted and flashed the chip successfully. On resetting the console everything worked fine.

Symptom: Random black screen on boot
Problem: Bad modchip. We are still investigating the actual cause of this problem (faulty flash chip suspected).
Solution: We swapped with another DMS4 Pro, worked perfectly after this.

Symptom: RSOD while booting upgrade disc
Problem: Bad solder joint on 3.3v (A) on PS2 motherboard. Its possible that with a bad 3.3v connection BIOS patching will still work ok but CDVD authentication will not.
Solution: Once the 3.3v point was re-soldered, everything worked fine.

It seems that more often than not, when there is a problem with a DMS4 install it is down to installation rather than a faulty chip. This is also reflected by the fact that so far we have not had any complaints from our larger customers, the only problem reports have been submitted via these forums. Please, if you have problems then double check your installation before blaming the modchip If you think that you have a damaged DMS4 chip then the best way to verify this is simply to swap it for a different (if possible, known working) DMS4 chip without changing anything about the installation such as shortening wires etc. If the console starts working normally once the new chip has been swapped in then you can be fairly certain that the chip is at fault and not the installation. While we do have quality control measures in place, occasionally faulty chips can make it through. In the case of a mal-functioning flash chip this can be very hard to detect at the manufacture stage. We openly admit that a very small percentage of chips may be faulty, however these chips will be replaced with working ones. If you are sure you have a faulty chip then please contact your vendor for a replacement.

I am going to be posting a troubleshooting thread soon based on our current good soldering practices but updated with findings from the consoles we have received from forum members.. keep an eye out for this!
