Hello guys 👋

I have two Xbox consoles - a 1.6 PAL unit and a 1.4 NTSC-J unit, and both of them are chipped but have stopped working.

The 1.6 PAL unit can no longer power on. It was working fine for two weeks, before it suddenly stopped working one day. I suspect the PSU's the problem.

The 1.4 NTSC-J was working fine, but I think I killed the Winbond modchip after flashing it with the wrong BIOS image fro, the Hexen disc. The EvoX badge no longer appears when I power it on, and I am always getting error 05 from my unlocked hard drive.

I just ordered this item (https://www.ebay.com.my/itm/193680862468), it's a 1.1 motherboard with XeniumICE modchip and 128MB RAM upgrade.

The seller assured me I can transplant this to either one of my Xbox case.

I read somewhere (I forgot where) that 1.6 Xbox cases are different, and will short circuit motherboards from earlier revisions, but I was unable to find concrete evidence of this.

Can anyone confirm this?

Also, what else can I do to try to revive my NTSC-J 1.4 console? I don't have soldering skills.

You cant put a 1.6 board into a 1.0-1.5 case or it will cause damages to the bottom of the board. 
 

I think you can put a 1-1.5 board in 1.6 case though you’ll just have one screw hole with no place for the screw.

With the 1.4 you could just use a modchip instead of the onboard flash that should fix the problem

Yes you can fit a version 1.0-14 motherboard in any version case but you need to modify the 1.0-1.4 case to fit a 1.6 motherboard.

Also just i case you are not aware the PSU from the 1.6 is not compatible with the 1.2-1.4 and the same the other way a 1.2-1.4 won't work on a 1.6 board.

It sound like it may have a modchip already, maybe post a pic of the board

The easiest way is to fit a new modchip.

Soft modding is like masturbating, It gets the job done but it's nothing like the real thing.

Yeah my 1.6 almost die by that, I put my motherboard in a 1. Something case bough in Mercadolibre and blout out a transitor, for my lucky was easy to fix, just put another npn transistor there and done, the next stuff is cut the metal from the screw hole and reassemble the console

This is the modchip installed on my 1.4 motherboard, which has been soldered on.

This is the modchip installed on my 1.6 motherboard. Whoever did the mod did a better job, because it has the headers allowing the modchip to be easily removed and replaced.

In the case of this particular console, I believe the chip is fine. I believe the problem is either with the power supply, or the five capacitors on the motherboard.

The BIOS being flashed was most likely not the problem just the method used to flash it to the modchip erased it but never wrote the new BIOS to the modchip.  The Winbond flash chip on the modchip is most likely blank now.  Not being socketed makes it a bit hard to remove it from the socket, like most Aladdin XT's have, and use an external programmer to reflash then resocket it.

I got in touch with a local guy here... he usually works with PlayStations, but he is willing to give my Xboxes a look
I figure there's two solutions

1. Remove the modchip from the PAL console and install it on the NTSC console

2. Rewire the 1.4 power supply to work with the 1.6 motherboard

I know the odds of me walking away with two working Xbox consoles is slim to none (which was why I ordered the 1.1 motherboard from Australia), but I do hope I can get one working Xbox out of this.

It's not just a simple rewire the 1.6 needs a 5 volt standby and the other versions have 3.3 volt standby.

dammit 😪

sold the only real solution left is to transplant the modchip from the 1.6 PAL to the 1.4 NTSC?

Or get a new PSU.

Even if you fitted it to just lock a HDD to the main board the you could TSOP flash it.

on the version 1.6 board there is a transistor that fails that will stop it from powering on, you should be getting close to the voltages on these 2 transistors

I'm sending both Xboxes to a guy tomoorrow... I am hoping he can bring them back to life.

At least if the 1.6 motherboard is confirmed to be working, i can order a replacement 1.6 PSU from eBay

Yup those transistor blout out if you put the mobo in the wrong case, and yes is pnp not npn, I don't know what I thinking when write my first comment

 

Here go a trick if you damage some of those transistor and the local store don't have surface mount, put a 2n3904 in replacement, is the same transitor the difference is the pin out and package, but is easy do it just compare the datasheet and check what pin is colector, what is emissor and base, them solder in the place of the pads, that's how I fix my console on the cheap 🤣 I guess the trick works too for the mmbt4403 reemplacing by 2n4403 vertion

      Pulled my og xbox out of storage, used it for a few weeks and then packed up and moved. Now when I plug it in and turn it on, I get the Christmas lights. Would like to replace the motherboard with a 1.2 - 1.5 model so I can use the same power supply I already have. I have an openxenium coming so don't need any of the drives. Thanks.

      I've two 1.0 motherboard sets (ie. motherboards, controller daughterboards and power supplies) for sale. Both have clock caps removed. Both working - no issues. 
      One of them has some clock cap damage (namely C7G6 missing). That cap (C7G6) is part of clock circuit so as long as you don't plan on bringing back the clock cap it's not used and not needed.
      Price for the lot: 50 Euro plus shipping (I'm in Ireland). Shipping to UK should be around 5-10 Euro max. Other EU countries - please ask.

      Hello.
      I am doing an expression of interest post here, have any of you done a polymod recap to a Original Xbox motherboard?
      I have a 1.0 and a 1.1 im looking to recap before I can put them up for sale (I do this with all my Xbox consoles once I receive them to ensure that they go for another 20+ years or however long) and noticed that the 1.0 and 1.1 units are 1500uf 6.3v for each four capacitors near the CPU and GPU, I have seen on AliExpress that they do indeed have 1500uf 6.3v polymer capacitors available.
      Would it be worthwhile to recap them with solid capacitors? the capacitors I am looking at are low ESR which is recommended for Xbox recapping, and if anyone here has done so please share your information and pictures of the motherboard after polymodding if possible
