RGH3 Chipless Glitching!!

FAST6191 · Nov 29, 2021

Very shiny. 9.86A supply on slim says I have a corona as my main machine so will probably look at that as I really do miss having a homebrew 360 (USB /HDD loading, region free, cheats, XBLA and DLC is so nice to have. RIP little JTAG), though I also have a 360 that failed the DVD update and have been meaning to RGH for years now so might look at that too. Do also have a Jasper with the NAND reader already wired in (and possibly even some dumps, was set to be JTAG but owing to an unfortunate event in a LAN session about 2 weeks before that dropped for real...) so might have to figure out if I have a machine with a suitable parallel port.
Also I am really not a fan of soldering in NAND bothering options for the 360. So tempted to get a nicer to use setup here even if it is ultimately going to be less than 5 machines I do this on.

question is will rgh 3 work on E since it attacks a different part of the 360 w/o a chip (iirc you had to desolider something to reach the attack point on the E For RGH 2

Corona E's yeah, Winchester no. It's the same exploit but glitches at a different post bit. Still uses the RST line which is still cleaned properly on a winchester

I decided to get my dead dvd drive Trinity and have a crack at this.. I've Dumped 2 (matching) Nands and soldered the SMC_PLL and SMC_POST1 Points..
Now I'm not sure where to go next..
Do I Flash the "RGH3_Trinity.bin" as a ECC? I have Jtagged and RGH a couple Consoles before but it was so long ago I forgot most of the steps

EDIT: Crap just realised I haven't got a 1K-10K Resistor.. Down tools for a few days till I grab some, 2K should be ok..
May as well grab some thermal paste while I'm at it

Is it a 2 wire mod?

I have a RGH with a chip.
Would be interesting to understand what you need to do to go from chip to chipless.

Why would you though? Just for little faster boot times? Not worth the troubles and risk to me, imo. But is def cool for future mods.
Depending on Mobo, some 2 wire, some are more.

I wouldnt call instaboot a little faster boot times. Def worth it for me.

Nice. Maybe one day I'll redo my trinity. Installed it when rgh first appeared before all the timing files, different installs etc, when it was more install it and pray for good boot times. Not terrible, generally goes within 15s, but a big difference to the more modern stuff.

Just not sure I can be bothered yet, don't really use it. Was a backup for my jtag falcon, but apparently that's immortal and just goes on and on.

I have a RGH1 chip and it only takes about 10-20 seconds to boot. If people can't wait that long to play, more power to ya! I normally turn on the x360 and go get drink/snacks/go pee, and by time I come back, it's ready.

It's not about waiting anymore since boots are like retail. It's about having the best.

Sad but I gave my 14 year old nephew a RGH xbox couples years ago, w 500gb drive and full of games/ homebrew/etc. I asked him few days ago about it and he said he doesn't touch it anymore at all. (Dumbass Fortnight Fan) So I told him I want it back! I already have 2 of em, but not letting him just throw it away, or let it sit in garage for years!

Wow that PPL point is absolutely tiny

I originally soldered to the resistor next to it..
Luckily I realised my mistake before it got too far.

guess r-jtag name is taken

Rgh can be done with a microcontroller, but it needs to be pretty fast, iirc the Rgh prototype was done with a mcu, but moved to asic (cpld)

I can try this on a jasper board I have

RGH3 be like:

View attachment 287457

Or buy a Devkit 360 and have a "factory" chipless rgh

It's like jtag and Rgh had a baby

What are boot times like compared to a chip, as rgh 1.2 gives instaboot for me, trinity was the only one I had that took a few cycles

If you already have a chip and instaboot just leave be, you still get the same end result

Just makes it easier for those who don't have a modded unit

Update!! Falcon RGH3!

Ooh, I'm pretty sure mine's a Falcon. I never bothered doing any mod to it because it's a Lite-On drive and I didn't feel comfortable sticking a metal probe in there to get the key, RGH seemed complicated (some tricky solder points) and the parts for Xbox 360 modding are so overpriced. But this looks easier.

$20 for Jr programmer

$5-10 for cpld board

If you have soldering equipment it's not that costly

Now the only thing left is cpu and nand swapping to convert retail consoles to native devkits, wonder if one could install a cpu socket lol

Buy a xdk instead of hacking together a ghetto xdk, in a nutshell that's what you're doing

efuses don't really matter, you can run any dash you want natively, and some have 1gb of ram instead of 512mb

Don't buy a Devkit if you don't know how to really use it, they operate different from a jtag/rgh/retail

I wonder if it's possible to upgrade a retail unit to 1gb

ploggy · Dec 3, 2021

Muhahah I only gone done did it

Trinity from Stock to RGH3! LOL

ploggy · Dec 3, 2021

Bits of advice before I forget:
For me J-runner wouldn't flash the RGH_Trinity.bin says it wasn't a ECC file, so I had to go into "Advanced>Custom Nand/Timing File Functions" Then select.. Command "Write" Size "16" then "Run" it says write failed for all blocks but Xell still booted and displayed my CPU Key

(saw this tip on Reddit)
Don't boot Xbox with Nand Flasher still attached (I not 100% sure it's necessary, but I wouldn't do it

everything else is in the Readme..
