Botched Tsop Soldering - 1.0 - Repairable?

Recommended Posts

I have an Xbox 1.0. I have an Xecuter 2.3B Lite+ mod chip (solderless with the pogo pins).

It was working fine both with or without the mod chip, however I was keen on changing this to a TSOP as the d0 pogo pin can sometimes move out of position causing 3 boots then FRAG (Christmas Lights). Through a combination of bad skill, a bad iron, and bad solder; I managed to lift all of the solder pads in question (R7D3 and R7R3), plus one of the alternate solder points to R7D3.  See the attached images of the board with the lifted pads highlighted.

Now without a mod chip, it Christmas Lights. I wasn't expecting this as I thought lifting the solder pads wouldn't actually cause any issues (since they are all at the end of a trace rather than in the middle), just prevent me from performing a TSOP.

With the mod chip it still works fine. Also strangely if the mod chip is switched to Disabled, it now boots the mod chip. My understanding is that this indicates there is something so screwed with the TSOP that it's booting from LPC even without d0 being grounded.

I'm wondering if there is anything that can be done to repair the TSOP here? I have checked every trace I can in the vicinity with a multimeter and they all seem to have continuity. The R7D2 resistor seems to still be connected just fine. There are a few traces I can't really check as they go under the Nvidia chip.

Or am I best to give up on the TSOP and get an Aladdin XT-4032?

Found these two pictures for v1.0-1.1 and v1.2-1.5 showing the traces to be connected to enable writing to the TSOP.

Thanks both (and thanks Kaos for replying to my Reddit post too :)).

I will give it a go.  But can I just understand, is this likely to repair Christmas Lights (3 boot then FRAG?).  I get that these are alternate ways to bridge the points to allow writing to a TSOP,  but I wasn't aware this would solve the failed boots.

I would suspect that the stock Bios Is damaged as the damage to the board is not that bad

There is a post about a version 1.0 Fraging.

You could try that as a fix thats providing that's it not the 1st 256kb of the bios

Fitting your mod chip with out using the spider option would be the way to go.

      Purchased a Xbox V 1.0 that has the Xecuter X3 mod chip, unit wouldn't even boot at time i received it ( sorry been otta this for like forever and just getting back into it ). After numerous trials and errors i finally got it to boot up, switch configuration on front. Anyways seems like its missing the backup that should be on the mod chip itself, doesn't seem to matter what i try cannot find it, other problem is it only stays on maybe 45 mins and shuts down, i think its a power supply issue, going to try another power supply this weekend since i do have a good replacement for this version. Other issues is cannot turn unit on with power button, only with the eject button, also another weird issue is when its first plugged in it comes on without touching any button on the front, lots of strange issues going on here, maybe someone may have a bit of insight to help resolve these problems. First thing i did was remove clock cap, had leaked a little but not bad at all, area around it got a very good cleaning and looks great

      Hello,
      I recently got two broken Xboxes and was able to build a working console from both.
      The Xbox has a softmod and I'm thinking about flashing the bios. How do I do that best?
      It is a XBOX version 1.4 (Winbond) and I would like to transfer everything via FTP, because I don't have a DVD burner. 
      I have read something about HeXEn and Tsop but I am now rather confused.
      Can I also bottle the Bios over FTP, if so how? 
      Do I have to remove the softmod and is it still possible via FTP after flashing?
      Thanks in advance.

      I have a TSOP v1.0 that I did a fresh install to a 2TB hard drive using HeXEn 2018.  I then installed XBMC4gamers as my default dash.   Now I am wanting to know what I need and what I can get rid of from the HeXEn install. Since I use XBMC4gamers I had two copies of dvd2xbox.  I already deleted the one HeXEn installed, and I deleted xb partitioner, figuring I won’t need it again on this Xbox.   What else don’t I need?  HeXEn put a lot of stuff on the E partition.  I’m wondering about the contents of the HexIns folder, HeXEn Tools folder, and the delete me folder.  What is Config Magic for?
       
      And unrelated but, can anyone point me to where I can find a copy of the controller tester?
