Xbox 1.0 FRAGing even after modchip install


Recommended Posts

So i have got an xbox revision 1.0 for parts. Inside the motherboard was pretty much immaculate with non-leaked clock cap. Sadly the xbox just FRAGged. I did lots of troubleshooting including dumping the eeprom with raspberry pi, testing it with different psu or trying the TSOP bank split trick for coma console.

I thought, that the TSOP must be faulty so i ordered aladdin xt. However the holes on 1.0 are filled with solder and hard to clean up. In the end, i soldered each leg of the pinheader individually. It looks ugly, but there are at least pretty wet solder joints and modchips do fit in it. Sadly it still frags.

I have:

1. Grounded the bottom d0 point

2. Grounded BT on the aladdin

3. Tested the aladdin in my 1.6 and then reflashing it with indbios

4.  Replaced a R7D4 resistor i accidentally desoldered

I also remember, there was possibly a short at Q7R1 part. I fixed it, but two pins next to each other are still shorted according to multimeter. The two pins are those closest to the Q in the Q7R1 marking (left down side on the bottom side picture)

Where's the modchip?  I don't see it connected to the LPC Debug port.

 

Double check all of the soldering to the pins installed in the LPC Debug port header location.

The modchip is a normal aladdin xt clone from ebay, that worked normally in my 1.6. I even tried flashing indbios into it. I have checked the soldering and i can say there is definitely good continuity. Only non-clean thing there is the flux residue. I'll check again if i haven't burnt the trace at the point, where it connects to the via tho.

 

EDIT: Fuck the 1.0's filled holes. I can upgrade RAM, but i can't solder pinheader to 1.0 xbox :D

Next time i'll install it probably with wires or something

Use a solder removal tool (solder sucker) or solder braid to remove the solder from the holes so you can install the pin header.

I don't suggest using the quick solder installation method for any modchip.  Quick and easy to install - a pain in the @ss to take off later. :)

 

Never removed one. But I also never have soldered one my self that way. How ever, it was just a suggestion (maybe not the best but better as wires - I think).

Some solder braidand, flux and a "hot" iron are ofc the best way to do it. In case it will not work, I do it some times with a cannula of a syringe, that works pretty well.

I might have been using maybe a shitty chinese soldering tip with bad heat transfer, but i don't really know. Anyway the problem is not anymore with the pinheader install, but with the fact, that it still frags even after installing the modchip

Is it Red/Green flash or some other colors like Red/Orange or Green/Orange or possibly Green then Red flashing.

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

It always reboots three times and on the third reboot it flashes red and green

FRAG'ing with a modchip installed is generally a bad connection from the modchip to the LPC debug port.

If you disconnect the D0 ground connection, does it boot the stock BIOS or FRAG as well?

the xbox did not work before in the first place. i thought it was tsop corruption

If it was already FRAG'ing before the modchip install, it's hard to say what the problem is.

Do you know what version the console is?  Edit: Went back to look - v1.0

I believe the most common cause of fragging is a dead hard drive.

Is there a number displayed in the upper left-hand corner of the Your console needs service screen?

Edit: A v1.0 will not show the number to aid in determining the cause of the frag.

However with a modchip installed, the modified BIOS should have an error number displayed on its error screen.

The xbox does the Triple-reboot frag. nothing ever gets displayed on screen and xbox just reboots. EEPROM dump was fine when i tried dumping it

Some major component checked at startup has failed: CPU, GPU, hard drive, or DVD drive. Most likely the hard drive has died or a cable is not connected well.  Disconnect all of the cables from the DVD drive and hard drive and the IDE cable at the motherboard.  Reconnect them all, power on and see if anything has changed.  

Edit: Measure the voltage levels present on the hard drive's Molex power connector:

  • Yellow = +12Vdc
  • Red = 5Vdc
  • Black = ground reference (0Vdc)

I am testing this xbox w/o hdd and dvd drive connected. PSU voltages are well and i tried it already with different psu. Sadly it seems, that this xbox is not going to be easy fix. i am envious of people, who have "bricked" xboxes, that are just non-ejecting dvd drive, fucked softmod, faulty hdd or bricked tsop

The Xbox will FRAG (Flash Red and Green) without the DVD and HDD connected.  The BIOS checks that all components are responding and if not displays the error screen.  V1.0 consoles with the 3944 version of the BIOS/kernel do not show a number in the upper left-hand corner of the screen to assist in determining the cause of the problem. Later versions of the Xbox BIOS do which helps immensely in determining the cause of a FRAG.

It is still fraging  with a modchip. I think this one is a lost cause.

I just want you to know that I am basically working on the same thing you are. I posted my first ever XBOX forum question last night (or 5 AM this morning however you want to look at it) since I started modding last year. Then I found this thread which begins to answer some of my initial questions about general diagnosis. For example I was not happy with my LPC header soldering at all for the same reasons you had removing the pre-loaded solder that exists on the 1.0s. There is a YouTube of a guy just doing it like it's nothing but at my pace it was going to take me a week with either soldering wick or my solder sucker. At least with my heatgun it was over. 

The statement below was kind of confirming yet my XBOX doesn't boot without the modchip too so it's less obvious what the problem is.

      Not sure if anyone has yet, but I have been running a diff between Barnabus Kernel Repack and the 4400 leak Kernel Tree..
      I've only just started looking through, and I have next to no C++, C and C# coding skills so bear with me lol
       
      They seem somewhat the same, but there are quite a few files with parts of code removed or added, on both branches. But Barnabus is reliant on precompiled objects (obviously as it's a smaller, almost stripped down and made 'easy' release of the full tree)
      There are some comments in Barnabus code that isn't in the full tree + CPXXUPD code, and some are recorded more 'formally'
      (i.e private\ntos\init\init.c line 244 - 254 in both branches)
      One other thing is the 4400 tree is set to have 'complex's' edits definable where possible, which there are a lot..
       
       
      One thing that really interests me, is Barnabus uses BIOSPack to pack: 2bl, remainder and kernel into a 'Working' rom (I use that word loosely).
      The 4400 tree uses rombld, which requires: preloaded, init table, bootloader, kernel and a rom decode file(I think).. this is a drastic difference to BIOSPack.. But the main issue with Rombld is it will not produce a full rom.. by default it will error on the 'preloader' being to big (9008 bytes not 1664 bytes)..
      To get around that, we can either build for XDK Systems.. 
      Or as I discovered today: modify 'private\sdktools\rombld\rombld.cpp' Line 879 from (2 * 1024) to (21 * 512), to allow rombld to accept the 9kb preloader file.. (I haven't tested a bios rom built with this edit yet)
       
      I will post here anything else I discover!

      Hey guys,
      I just found this forum googling for an instruction for my modchip. Probably 14 years ago i installed this modchip and it worked fine for years. A few years ago after i moved i wanted to use my xbox again and it dind't work at all. So today I atemped another try. I reconed a loose cable which supposedly needed to be connectet to ground, which i did. Now the Xbox does boot the original bios. I can see my copied music and game saves. Trying to start it with pressing the power button for  2 seconds sometime leeds to atempt to start in whatever bios is installed on the modchip, but it restarts in the original bios. Nevertheless the LED on the modchip does light up on start. Do you have an idea how to get it to boot up with the modchip or a procedure to test if the modchip itself is actually working? Maybe you can point me to thread i missed.
