TSOP Flashing Unlock points 

if you are unsure which Xbox version you have click 

TSOP unlock points for version 1.0/1.1 Xbox

This is the top of the motherboard
Connect the two solder pads at R7D3 as in photo above.

This is the bottom side of motherboard
Connect the two solder pads at R7R3 as in photo above.

All Ver 1.0/1.1 Xbox's with a 'SHARP' TSOP chip must also connect the additional red wire as in the photo above. All other TSOP's DO NOT require this step. 

TSOP Unlock points for all Versions 1.2/1.3/1.4/1.5/ Xbox's

This is the top side of the motherboard 
These Xbox's have both points located on the top of the motherboard, for the first point connect the two solder pads at R7D10 as in photo above. For the second point locate the junction between R7D2 and R7D1 and connect the two solder pads as in the photo above.

After the solder points are completed you should re-assemble your xbox (but leave the top cover off) when the power button is pressed it should boot normally as it did before you started.

Note if you get the message TSOP write protected while attempting to Flash the TSOP you might need to check and resolder the points to ensure a good connection was m while attempting to Flash the TSOP you might need to check and resolder the points to ensure a good connection was made.

To split Split a 1MB TSOP (v1.0, v1.1) into 4 banks of 256k, the following picture explains how to accomplish this:


Note: If you have a 1.6/1.6b Xbox, it has no TSOP and therefore you cannot flash it. You will have to install a modchip or softmod.

Just an additional note for Blake's post, you can split the TSOP in the 2-way split to have two 512k halves. if you complete this, it is recommended that you cut the A19 trace shortly after your solder point to keep the chip it is connected to from getting too hot.

I take a speaker wire, strip out one tiny strand of copper, tin it, and lay that across the write points and solder it down.  Then I wiggle the excess till it breaks off. Never pulled a pad using this method and it takes much less time. 


I don't use alt points though

I’ve used 30awg kynar because I was using a crappy iron. Now I use a good iron and learned the air bridge technique and can do it in 5 seconds per bridge.

the wire method is a safe way to go for beginners and as long as it gets the job done. Glad this guide was reposted, had to bridge the alternate points on a board with missing pads.  Using 30 awg kynar it was a breeze.

using wire on the alternate points is actually quite easy to do.

elaborating further,

what does the boot look like after this soldering job is done?
how do we proceed with unsigned code?

"flashing the tsop"; is that done with hexen?

which bios works best for 1.0/1.1 VS 1.2-1.5... any difference at all?

Thank you kindly for this thread,

I successfully TSOP flashed my 1.4 on the weekend!!!

used ind-5003 67

Stupid me didnt realize you need to softmod it then tsop it, which is just SO MUCH FREAKING FUN!!!!

really it was, so far this seems even better than a modchipped box. Why? some kind of placebo thats making it emulate better.

      Hey everyone, I'm new here.
      I have two OG Xboxes. The first I bought pre-softmodded and which cannot be turned off by the power button, I gather because a trace was eroded; I did take out the clock cap and cleaned it up, however. And the second I softmodded myself as a project because a guy was giving it away for $5. This one doesn't have power/tray eject button problems, however, it did start to make a buzz (the HDD?) or loud fan noise before this happened, but I'm not sure if that's normal for this model. Yesterday it died on me as I was playing a game, for the first time. I took it off power and gave it a rest and then tried again, and it died after a few seconds. Now it doesn't turn on at all.
      I did some research and given that this one never seemed to have leaked capacitor fluid, and given the caps all over are fine, no swelling, I think it must be the power supply.
      I thought I would check with you guys first, as I am not very computer savvy and if all I have to do is solder these, I'm not sure I could do it myself tbh, or if it would be cheaper to just hire someone who already has the tools and know how. But I need to know if these are indeed the culprit.

      I was given two broken original Xbox consoles to try and fix. After fixing the issues with one of them, I tried to test it. As I didn't have a controller for it I bought an adapter like the one in the picture (Adapter) to try and use either a USB arcade stick or one of my wired controllers for PC, Xbox 360, or Xbox One. I eventually bought a controller for it as I could not get anything to work with this adapter. So I am wondering, does this adapter serve any purpose? Has anybody gotten an arcade stick kit like the one in the second picture to work on the original Xbox?

      Hello, I recently bought a used OG that was modified by its pervious owner. It appears to be a soft mod.
      The Xbox first boots into the stock MS dash, but with the "Xbox Live" tab replaced with "Phoenix" 
      Selecting it boots into the UnleashX dash. 
      I like this setup since I think the stock dash is cool, and has a better game saves system than any of the dash big replacements. However, when I first tested it out it was fragging, and the HDD (which was replaced at some point via chimp with a 128gb one) seems to be in poor shape based on the sounds it was making. I am considering on giving it a tsop flash for the sake of keeping it alive, but It would be cool if I could keep the dash replacement. 
      Any info on this "Phoenix" softmod and its viability as a hardmod dash replacement would be great.
