TSOP Flash Tool

Anyone have a wiring diagram for a TSOP programmer?

I've got a box here with a bad flash. Perfect hardware, just a bad flash. And I'd like to get it repaired.

Failing that, anyone have a source for an old style 26 wire modchip and the associated programmer?

Thanks in advance.

Well installing a modchip basically replaces the tsop. So get a duox on their with cromwell then flash your hacked or dev bios

 

If I use a chip I need to be able to disable it on the fly (as can be done with the original 26 wire chip) after boot and then reflash the TSOP properly. I didn't think any of the "smart" mod chips with multiple banks could do this, if they even work with the MCPX X2 boards. Don't they require MCPX X3 boards?

It's more a matter of just wanting to restore an otherwise fine piece of hardware.

Hmm,do you mean 29 wire modchip.

 

That's probably correct. I never had the need to deal with chips for retail systems. Got the box from a friend awhile back. Some idiot tried to flash a EvoX BIOS to it. Of course that didn't work.

By the time I got it the 29 wire chips had already been phased out by resellers and I'd been advised that the new "smart" chips wouldn't work on a X2 board, let alone the fact that they can't simply be shut off on-the-fly. As a result the box sat in a box.

I'm being told that I need to make space though so that means either fix it or kick it and I'd much rather fix it.

Since I know exactly what the problem is, I also know that reflashing a proper BIOS will revive the board. It's just a matter of figuring out the easiest way of getting the BIOS onto the TSOP. Were I a bit better at soldering I'd just flash the BIOS I need to a retail system and then swap the TSOP chips but sadly, I can't hand solder surface mount. Just not that good.

This should do the trick.

Those chips bring back such bad, bad, memories.

Best of luck installing one hl7 ;p.

I could solder the points fine, the amount of wires and mess it created was impossible to manage though.

is that the only way to fix the TSOP? I have a DVT4 that apperently have been through lots of stuff (before anyone asks this was done but the previous owner and not me, I take care of my stuff ) and are need of a reflash of the TSOP..

 

Well you could always desolder the chip, reflash it in a programmer and then resolder it.

The chip Pikkon linked should do the job, assuming one can get a dev BIOS into the 512k bank. After all the chips don't ship programmed.

Christ why are you getting a 29wire chip when a 1 wire one does the job. Well not one wire but still its 1 if you only count the D0 point since the rest of the conections go on the LPC.

get a duox chip and flash what you need

 

It was always my understanding that if you boot the system via a chip connected to the LPC port that any attempt to flash will flash the chip on the LPC and not the TSOP.

So while a LPC chip would allow one to get the system up and running (you'd still have to program it outside the system on an external programmer) I don't believe it would allow you to return the system to "stock" condition, which you could do with a 29 wire connection.

I need to read a little more before I post OH: I missed your second post, ignore that post^

 

No worries. It happens. I've made the same mistake before.

For most situations something like the DuoX is ideal. Unfortunately I have one of those "non-ideal" situations.

You can flash tsop with lpc modchip, but not sure if it'll work on debug/devkit...
http://forums.xbox-scene.com/index.php?showtopic=459116 - guide here, basically flash special bios, remove chip after boot, flash bios to tsop.

 

Retail BIOS will not work on a dev kit.

That's what messed up this one in the first place (as mentioned earlier in the thread).
