Physical Eeprom Replacement
« on: June 22, 2005, 04:08:00 AM »

Well, I talked with someone from xboxrepairguide.com (wish I knew their name so I can thank them), but I asked if my v1.1 box EEPROM chip could be used in my v1.3 box w/ the boot problems. He said this: "You should use a 1.2-1.4 eeprom, certain 1.1 eeproms could work but the 1.1's have two types of video encoders, the conexant and the focus, if you uses a 1.1 eeprom from a conexant system on one that has a focus chip it will cause problems." Mine are both Conexant chips, so if my friend that installed the chip isn't able to repair my EEPROM by: placing the ICE in a working box, setting it to instant boot to my X2 bios, then when the chip is placed back in my box it will boot to my EVOX dash, where he can hopefully get the Enigma Switchdisc to pickup (I got a samsung so I hope it reads) and from there he should be able to press "b" to switch it to NTSC-M, restart the box and have it work. Hopefully this will work otherwise I will have to desolder my 1.1 box's eeprom and place it on my 1.3 box, which I dont want to do, but I can get all my gamesaves back, so it is a mixed bag, and hopefully all goes well and nothing fries.

I have a v1.4 with audio and no video, I think it's and an eeprom issue.  I was refered to this fix.  I haven't tried it yet because I don't have a good v1.4 EEPROM yet to use.  It seems like it could fix your problem.

Yea I have heard/seen that, but I am not quite able to follow it. So maybe if one of the smarter board members sees this maybe they could explain it some more, because I am totally lost.

That only would work if you could see the xenium os, but since you can't in this situation, its useless.

Physically swap the eeprom chip to one not set to ntsc-j (can even be one from a different version...), then boot to the xenium OS and reflash your old eeprom. Should work cool.gif

Not really, in this case, send your box to xboxrepairguide.com for $70 bucks (dont have to include anything but box) and then go buy yourself a new one. I have my friend trying to swap my v1.1 box's EEPROM and put it in my v1.3 (both Conexant) so we shall see if it is a success, hopefully it is because I want to buy a psp and if I have to buy another xbox I am going to be mad as hell, but hey, you win some and you lose some, and it was my wrongdoing that got me into this mess anyways. So we shall see how it goes, I will keep you guys posted

guys this can be much easier to fix with a modchip that has a bios embed with an eeprom.  it will boot fine and u can run configmagic and load your xbox eeprom and change to the right video mode.  all you do is your chip has 2 banks flash the second bank with x2 4981 embed with an eeprom using xbtool.  make sure its a backup of your eeprom from when it worked
