Hi guys,

I recently attempted an Aladdin XT plus modchip install on my xbox V1.0. Other then trying to suck out the solder from the LPC ports, the process was relatively smooth. When I first went to boot the box, the Aladdin instantly smoked hard so I it off. At the moment I'm trying to figure out whether it was my install error or a faulty chip. When I remove the chip and boot the xbox, it boots fine and normal. As soon as I add the chip back on, which doesn't smoke anymore, the xbox FRAGS. I tested the LPC pins and didnt get any continuity between ones I shouldnt have. I then tested to make sure the 5 and 3,3 voltages were still good and they were. I was gonna test each individual pin and see if maybe Im seeing 5V/3.3V where I shouldnt, but other then  that I'm not sure if it was the install, but instead just a faulty chip. I bought it from Modchipcentral and I've gotten good stuff from them before. Any input would be appreciated.

 

Thanks

Could be.  I usually order those in batches.  But I have had one that was bad.  Swapped in another and bam.  Also, give it a little wiggle jiggle.  I had one that was similar that just needed to be re-seeted.

As far as I could tell it wasnt the wrong way around, the installation orientation being with the red light pointing towards the controller headers. Im surprised that the chip wouldnt almost be reverse protected, at least I would think all pins would be 5V tolerant unless for some reason it shorted it to ground within the chip itself. Oh well, ill be sending it in for a return and hopefully this time itll be better. Thanks

It is quite likely at least part of the circuitry of your chip is burnt out. I would buy some more aladdin XT chips if I were you, then plug one into the LPC pins and test for continuity with each pin before turning it on again (I've broken three in my lifetime through incorrect installation). If possible could you show some photos of the LPC area on the top and bottom please?

Really?

5 Volt it to a chip made for 3.3 volt that's about a 1/3 more.

Reverse protection would not be needed if it's fitted correctly!

The supplier will probably swap the faulty chip as for what it cost them it's not worth the hassle.

      Hi Mates,
      I met the following issue, I try to explain everything... I'm totally lost in space, so I hope, you have some idea what happening...
      So, first, what you have to know:
      - I've got an xbox classic v1.6 without video and sound output.
      - When opened it, I found a MuppetX modchip in it. My friend inform me, he try to flash this modchip, but 1MB always gave an error message "mismatch bios size", so he flashed it with 256KB bios. That was the mistake of him, so the modchip never works again... (The LPC Chip is 49LF020A, like in Aladdin)
      - I flashed it with USB Programmer with many types of bios.bin, tried 256, 512, 1024 evom8+ for v1.6, I tried everything to use it again... But the only working solution was to flash it with 4*256kb = 1MB XBlast OS bios. But when I use XBlast NET bios flasher (cause I can't use any other way, just USB programmer), the flashed bios never works.
      - I checked all capacitors and all of them is in good conditon... I checked traces and all of them in good condition.
      - When I push (more than 5 sec) the power button, the xbox started and loaded the XBlast OS. Without modchip (power up with eject or just push power button) there is no video or sound output. If I change the Bank (I do not know is it bank0 or bank1), the Xbox turn off and turn on again...
      My questions:
      - Is there anyone who has an original dump of a MuppetX bios?
      - Which is the Bank0 and Bank1 on MuppetX?
      - Which BIOS size the correct for that? (As I said, I try 1MB first and all other sizes, but won't work...)
      - Why Xbox doesn't give video and sound output without modchip?
      Is it maybe an EEPROM error?...
      Thank you in advance!
      BR, Zsolt
