1.0 XBox Crashed During Modchip Bios Flash.

Recommended Posts

Hi I'm after a bit of help; my Xbox 1.0 just crashed during a bios flash (I was using HeXen 2018)

My Xbox will no longer boot (HD Error 05) and I don't have the adapter to flash my modchip on my PC.

Unfortunately I can't even recall what my modchip is, and I've long since lost the PC (Parallel?) adaptor it came with.

I've included a picture of the modchip, in case anyone remembers what it is.

Should I buy a new modchip? My soldering skills are not great so if there is any way of salvaging this solderers chip I'd be grateful.

Was it working befroe you tried to reflash it?

And why and what did you flash to it?

There is 10 points to solder with a new mod chip the hardest would be the D0 point.

You have nothing to lose try changing the switches 1 at a time and have the DVD and Hard Disk pluged in and try and reboot.

10 points eh? Thanks for the intel. I'm hoping i can find a way of reprogramming the chip via the port, the chip is a Xodus matrix.

It was partially working; it was reporting the size of the F drive differently depending on whether i was in XBMC or the HeXen application.  I thought a bios update might help.

No I get error 5 as I've got a new 1TB drive in it that I was in the middle of setting up, I don't have the original 8gb drive... If I could lock the new drive would it theoretically boot? ...I don't have they lock code either though... Got myself into a pickle here!

This is where it gets harder a new mod chip($5 Ebay Alddin chip) could be held in place to get the xbox to boot from a DVD in order to softmod it.

You could try asking your local electronics repair place if they could solder the chip in for you.

Once you have the device booting from a hard drive without the chip you could then reflash the BIOS using conductive paint to link the flash enable points.

Then the xbox will not boot because you have the softmoded hard disk but boot from the DVD and do a new full install.

With the BIOS flashed you don't have to worry about locking the drive and it will boot to your dash with either the eject or power button.

The software was no reporting the correct size of the drive because the bios did not support drives bigger than 137gb.

Even if you did find the programing adaptor finding a PC with a printer port and running XP.

Yeah that's what I figured about the bios, thanks for the help. I was hoping I could jury rig something to update the modchip however that's seeming remote. I've ordered a new modchip in case I can't find a way forward. I am thinking I may get another unmodded xbox and soft mod it then I can potentially reflash? (I'm building this machine for someone else and so far I've really enjoyed working with it so I may want one for myself)

      Hi guys, newbie to the forum. I've just ordered an Xbox One X and am now looking at a few games to go with it. Keen to buy Skyrim and Forza Horzon 3 (interesting contrast I know). The local game store has a deal for 4 Xbox 360 games for $20. Skyrim and Forza Horizon 3 are included in the deal, while their Xbox One counterparts are triple the price. So my question is, is it worth paying extra for the Xbox One version vs the 360 versions considering they are both "Xbox X enhanced"? Hope that makes any sense. Thanks to anyone with any advice &/or knowledge on the subject. Cheers

      Dvd drive power cord got shorted out now the xbox turns on and off twice then stays on with no video.
      No visible damage to mother board could I have wiped the tsop by shorting out the cable?

      Hi, i bought an xbox for 10€ a couple of months ago, i had to clean it, removed the clock capacitor and i also did a tsop flash (evox m8 bios)
      I added a 500gb hard drive, wich works quite fine, i tested it on another xbox and even a xbox 360! The thing is, the xbox takes a long time to boot, like 30 seconds, my other tsop 1.4 xbox takes no more than 15secs (give or take).
      I took a cheap chinese ide to sata for the xbox, it work well on my other xbox so i don't suspect that the problem can come from this. At first i thought that it was coming from the 80pins ribbon wich wasn't long enough, so i bought a longer one, but it didn't change anything.
      And on top of that, when i press both triggers + start + back in order to go back to my main dash, the xbox take at least 10 to 15 seconds to give me an error 07
      I suspect the dvd drive to be the issue, but why will it start with no other problem that the long boot when i press the power button, but fail to reboot when i press both triggers+start+back ? By the way i can hear two spins from the dvd drive, i think the xbox check if there is any dvd on it, so i tryed to insert a xbox game and the hexen disc, it loads, it takes a long time to load, but still..
      So, is there any way to bypass the dvdcheck to see if it's come from this, whithou having to make any power modification ? i read that it's possible by disable dvd check on a certain bios + hardwares modifications wich i'm not feeling quite comfortable with..
      Or if you guys think that it could come from somewhere else?
