SS_Dave Posted October 27, 2019 Report Share Posted October 27, 2019 I was playing with a different 007 Agent Under Fire game save hack and while flashing a new BIOS on a version 1.0 Xbox I flashed a 256k BIOS(STUPID I know). Yep it was FRAGing afterwards now you can either fit a mod chip and be done with it or do a 3 wire flash recovery by following the instructions that can be found by working the Google on the interweb. The instructions say 1 wire soldered to ground and the other 2 get soldered to points on the bottom of the mother board(pain in the butt as you now have to remove the PCB again), Me been lazy and not wanting to remove the PCB again found an easy way to do the 3 wire trick. {pic 1} You need a test lead with alligator clips both ends and a pin. {pic 2} Clip the pin in one end and the other on the metal shield(you did leave the metal shield in didn't you)and the point of the pin is gently held on pin 1 and 2 of the TSOP chip. {pic 3} Power on the Xbox and if all goes well your Xbox boots. Remove the pin that's shorting the 2 pins to ground. Now flash the correct 1024k (1 meg) BIOS. If you don't like the idea of shorting the pins on the TSOP IC the points in the pic below show the same points on the top of the PCB and the bottom of the PCB. {pic 4} 1 2 3 4 Inside the box on lower right of pic 4 are the same points as in pic 1 On side note I did try a mod chip and with some BIOS's the Xbox booted but with no video out but the Xbox was still showing on my home network and I was still able to network in to the box.

Ok, so I gave this a go, having never soldered before, I bought a practice board and did a few tests first. However I tried doing this by eye, and the wire kept moving, and for now I gave up, the 19 hole has solder in it, so I need to remove that. Silly question, does the wire go in the whole, or just has to touch the outer ring, and could I tape it instead? Quote Link to comment Share on other sites More sharing options...

my2k2zx2 Posted January 1, 2023 Report Share Posted January 1, 2023 I bought a 1.0 that boots 3 times then frags. I installed an Aladdin chip and it boots to the dashboard. Would this be something to try? I'd rather flash the tsop instead of using the modchip if possible. Quote Link to comment Share on other sites More sharing options...
SS_Dave Posted January 1, 2023 Author Report Share Posted January 1, 2023 I would try the 3 wire trick 1st as flashing the onboard bios chip when is failed needs the actual chip attaching to a external programmer. Fitting the mod chip is the easiest way to fix it. Cheers SS Dave Soft modding is like masturbating, It gets the job done but it's nothing like the real thing.

my2k2zx2 Posted January 1, 2023 Report Share Posted January 1, 2023 Nope, the 3 wire trick didnt change things, still did the 3 boot frag. Now to figure out how to update this mod chip as the console has a dead dvd drive. I'm all new to this, never owned an xbox before. Quote Link to comment Share on other sites More sharing options...

What is the mod chip? can you upload a pic to a file share and add the link here. Cheers SS Dave Soft modding is like masturbating, It gets the job done but it's nothing like the real thing.

SS_Dave Posted January 2, 2023 Author Report Share Posted January 2, 2023 I am assuming you have the pin header fitted? That chip looks used but it may still be ok ( see the solder at the black arrows) Add a wire link to join the 2 arrows Then you will need to ground the D0 point on the motherboard by adding a wire link (Black line) a per the pic below I highly recommend you use the alternative point on the bottom of the board Once that's done then refit the motherboard to the shell and plug the mod-chip on the board You don't need the DVD or HDD connected at this point. Power on the Xbox and hopefully you will get a image on the TV. Let me know what happens. Cheers SS Dave Soft modding is like masturbating, It gets the job done but it's nothing like the real thing.

my2k2zx2 Posted January 2, 2023 Report Share Posted January 2, 2023 (edited) That's my solder job, all pads were clean when I received the chip. I have the pin header and the bridge is on the other side of the board. I have the wire ran to the bottom of the board as well. I needed this hooked to the mainboard for it to boot to the dashboard. Without the chip it does the 3 boot frag. From here I'm not sure what to do without a working disc drive to try and update the modchip. I take it at this point the board's tsop is a goner without a full reflash/replace, which is out of my abilities and equipment.

SS_Dave Posted January 2, 2023 Author Report Share Posted January 2, 2023 I would say the onboard bios chip is toast.. With the chip fitted you can make a new HDD using a PC that will boot so you don't need a DVD drive or with the mod chip working you can fit a PC DVD drive to load the OGXbox 2021 v1.5.4 install disk to either use that disk to reflash the mod chip and setup a new HDD. You might be lucky and beable to reflash the mod chip as a lot of the new aladdin chips have a fake EEProm (49lf020) and can't be flash in the Xbox But you have nothing to lose by trying to reflash it plus you only need to reflash the bios if you are fitting a 120gb or bigger Cheers SS Dave Soft modding is like masturbating, It gets the job done but it's nothing like the real thing.

my2k2zx2 Posted January 2, 2023 Report Share Posted January 2, 2023 With the chip any dvd drive will work? I might have to go thrifting again for an ide drive if that would work. Quote Link to comment Share on other sites More sharing options...

I might have to go thrifting again for an ide drive if that would work. In a hard modded ( chipped or re-flashed bios) any PC DVD drive ( I have even tested a Sata DVD drive with a Sata2Ide adaptor) will read a copied disk like the OGXbox installer or Hexen but it can not read an original game disk.

my2k2zx2 Posted January 3, 2023 Report Share Posted January 3, 2023 Is there anywhere to get a new tsop? I'd try swapping it out and see if that does anything. I'm guessing that with a modchip the system wont care if on board tsop is missing? Quote Link to comment Share on other sites More sharing options...

I'm guessing that with a modchip the system wont care if on board tsop is missing? No as the eeprom ( TSOP = Thin Small Outline Package) that was used for the bios chip is no longer available. The only option is a mod chip or salvage a bios chip from a dead board but as the donor board is dead it may have the same issue.

my2k2zx2 Posted January 4, 2023 Report Share Posted January 4, 2023 No biggie. It's booting with the modchip so that's good for now. I've got a new 2tb hard drive and adapter on order. What is the best bios to try and flash the aladdin chip with? Quote Link to comment Share on other sites More sharing options...
