Great job MadBoxer.

There are not enough people that can solder, take good pictures and know thier way around photoshop too.
Also very nice of you to give credit to myself and blackaddr.

Thanks for sharing your work.

Great tutorial all 3 of you all

So will the new cool shrimp jtag tool be able to flash these fine without any issues. I remember when i did my zephs i had to do it manually with freeboot toolbox and copy the files, but if the the coolshrimp does it automatically then great.

Also on a side not boxxdr, i assume you have an electronics background? How did you go about figuring out this new method? Currently i use tuts to do my work. But would hope to actually figure things out and contribute such as you and others have.

Cool shrimps tool should work. If not there are other tools and methods so try it and if it don't work someone will help you.

I do have a decent eletronics background but the brains behind this is all blackaddr. All i did was come out with a very neat way of installing this. I also traced the jtag lines to find that alternate point mind you others had already found it before me. blackaddr actually uses my method to install it now so i am good for something.

Thanks for the kind words! I'm Glad to help. I've spent years on these forums as a guest learning from posts and tutorials just like this. I figured it is about time I make an account and start giving back.

Hey!

my box is randomly rebooting often in gameplay.

Its wired up with diodes now. I'm definitely going down and getting me some transistors and trying this.

Wish me luck

Not sure if this will fix it but it is worth a shot.

Nice tut. I followed and all went well.I have one question though , are the 2n3904 transistors the only ones that work? sorry if this has already been anwsered. thanks

Other types will work but they might have different pinouts. They also might not work right with 10k resistors if you use something else. So if you want this to work nice with the least chance of problems just get the right stuff. I really should start selling a boxxdr jtag kit with some nice wires, shrink wrap and all components.

Often when a circuit calls for a 3904, you can subsitute almost any NPN transistors and you wont notice a difference. However, why would you want to use others? 2n3904's are very cheap and one of the most common avaialble. Unless you have others laying around, there shouldn't be any reason to use anything else.

[syst3merror]

so can this method be used on all motherboard revisions? (Aside from where the other end of the wires end up soldered to the mobo)

Yes, eevn though this method was originally developed for the HDMI consoles, it'll work on Xenons as well.  MadBoxer posted a pic of a Xenon earlier in this thread.

awesome, thanks!

And awesome tutorial/mod Boxxdr!

back again and finish with the new wiring. had a little problem finding a 2n3904 transistor but found a replacement called BC547b but reversed pinouts on emitter and collector and works like a charm.

Thanks for the tut and time will tell if there was any wrong with the diodes I had earlier when i was experiencing random shutdowns and restarts. prob bad soldering.  

Good job finding a replacement and noticing the pinout was differnt.

[PimpleX]

I have about 90 x BC635 laying about doing nothing, ...dont suppose I could use them could i? Or are the specs too far off?

Cheers

Hi, first post here.

I have a jasper 16MB nand 7371 with cb of 6723 which I believe is exploitable. MFG date is
I followed this tutorial and the one mentioned earlier in google docs. I was using coolshrimp JTAG and read the nand with no errors.

When I flashed xell which comes with jtag tool the jasper won't boot with old diode method and bridging pin 4-7. Tried with jasper_6723_hack.bin and it just gives E79. I have checked and rechecked my soldering and its fine, no solder splashes or lose connections as I am using the alternate pin on the underside of the board...

Anyhow now I'm using the transistor mod for the jtag xell stage and modified xell so that it uses aud clamp for TMS and alternate point for tdi and all i get is rrod with 0031.

How are people flashing their jasper's to get xell booting?

p.s if i flash original nand back xbox boots just fine.

1) did you write your keyvault afterwards to the nand?  (or put it in the image before flashing it)?
2) or.. why didn't you use XBR_Jasper16_8955_3.bin as your starting point?  <<probably more important to answer.  then answer #1.

[boflc]

i just completed my first aud-clamp.  reading (for comprehension) how to build the appropriate xbr_*_8955 w/patched smc's took a while.  

i am concerned, to be honest, that if this unit ends up in someone else's hands it'll be coming back to me; either with an incorrectly flashed smc or just to update it.  bestpig REALLY needs to add smc_io support; or at least have a set of options (TMS == [drop down], TDI == [drop down]): there's only 6 popular combinations.  if folks have more complicated than that (and frankly, i'd be happy if TMS==AUD_CLAMP vs TMS==ARGON_DATA was the only option).

btw, the preceding paragraph is based on the fact that i only work with jaspers.  i completely understand falcons & zephyrs needing this method.  insanity4all highlighted the support issue about 3 weeks ago and it really did shift my perspective on methodology, at least as far as jaspers go.

anyway, i thought i'd share my work with this box.  it took me quite a bit longer than greg, and certainly much longer than RoL wiring or bottom ARGON_DATA wiring.

first, cleaned pins 1,2,4&7:
