OMFG ive read the techinal read out
So what don't you understand about the coolrunner being a hardware pulser?

By your argument, why do you still need the JTAG wiring in place once an exploitable Dash'd Xbox has the CPU key?

My point about A+ etc is it's meaningless in this field of work. Common sense about basic functionality of electronics is far more useful.

What 2 boards switching between each other? I hope you are talking about NandX and Coolrunner

To switch between RGH and normal, you need a dual nand solution and a way to enable/disable the power to the coolrunner board. that's all. NAND-X is a programmer for NAND/Coolrunner etc.

JTAG hack is a software exploit. When the software is upgraded efuses are burnt.

The "reset glitch hack" cannot undo the efuse burning so the old jtag exploitable kernels will not run.

The reset glitch hack is a hardware exploit allowing access to the boot chain early on. and patch checks, hashes etc if that's what you want to do.

If you change the nand then boot the Xbox without the rgh the the new nand will fail checks and wont run.

if you change the nand (eg with xell or patched kernel) with the rgh the checks are bypassed and the "hacked" nand will run without problem.

Took me ages to write this on me HTC desire so any typos blame that!

So I would need to buy something else to work with the Coolrunner? man this is the most expensive mod ever I already put 60 dollars into the coolrunner and the NandX, not to mention I have to get a cable to program the Coolrunner which I am looking into. Why can't it be just one item to solder in and you are done, I guess nothing is simple or cheap anymore.

As far as I understand nandx, coolrunner and cable will be enough.

60 dollars???? come one that's like 1 game........If you're serious about this and it's potential, even 100 dollars would be a good initial outlay......
and at OP - I hold no qualifications in electronics or computing to any extent although I have been using computers since the tender age of 8 - OMG that's 23 years lol, but I clearly understood from the start why the coolrunner needed to be a permanent fixture..it shocks and amazes me that you didn't, especially aftrer claiming u read the tech documents and understood everything

For the OP, if you read the tech docs and you're as advanced as you claim in Electronics, then -why- can't you grasp the fact that the RGH requires the Coolrunner to stay in place???

Coolrunner sends a timed pulse attack (assuming I read correctly) to glitch the XBox and allow unsigned code to be ran (IE: Xell). If you remove the Coolrunner, the board isn't getting a pulse, therefore it isn't being glitched and therefore cannot run unsigned code.

That's why it has to stay in. Coolrunner sends the pulse to cause the system glitch that allows Xell in the first place. Without that glitch, anything flashed to the NAND other than the original MS dashboard will be rejected by the system.

If you want it in simplistic terms, think of it like an old modchip. PS1 and PS2 consoles couldn't boot games from other regions without a modchip. Slims can't boot unsigned code without the Coolrunner, no matter what you do to the NAND.

OK i think im getting a better picture... i was under the impression that this mod would allow u to fully edit your nand and if that was the case then older freeboot would be plausible... i didnt claim electronics, and this is what i was stating as my theory. But having the coolrunner 24/7 is fine to me

It just sounded weird that after a hacked nand was flashed, to run US code something was still needed to run it so i thought hmmm? wats up here... does anyone get what im saying in theory? and also i thank you all for your input... good and bad,

i never intended to desolder the orignal jtag points and such... no thats required lol no point

---------- Post added at 09:00 ---------- Previous post was at 08:58 ----------

And yes i understand the pulse thing, thing is ive been to busy to read up on as many forums as i would like.. and yes i realize takin it away would not enable xell to boot... yes i knew that at the beginning of my post

sorry for the stupid post... not intending to waste anyones time

---------- Post added at 09:06 ---------- Previous post was at 09:00 ----------

Khain 13 thank you also u cleared up some fog.
But im sorry i was not able to do as much reading i only read the documents offline that came with the hacks and not much of TX forums, since it was the Big cheese documents, so which part of the M$ dashboard and where is it stored atm that cannot be edited (that requires the coolrunner) and such my field btw is more IT electronics are still foggy for me... i understand a bit, but havent gone down the road full speed... soldering is a passion. love it

---------- Post added at 09:14 ---------- Previous post was at 09:06 ----------

Well also yes i did read the tech docs i and i do understand electronics... u get into the math of it like deep sh*t it becomes a bitch, but just bc i dont state everything perfectly and the world was made out of curious questions, does not make me an idiot of a sort... if u can grasp what i was asking which would be if u put old freeboot on there if u could fully edit that nand (which it didnt entirely specify on the tech read outs.. from what i saw) thats y i had this ?.. been rolling it around my head then bam u can have old freeboot... just not the new mods like which coolrunner but old one... BUT yes i also know that jtag, and glitch are 2 totally different thing... one software which requires exploit. ker. and the other... pulses, yes i know.. i find it irritating to go on any forums to ask a question and if u ask it wrong or dont include any points of reference u will be treated like crap

---------- Post added at 09:17 ---------- Previous post was at 09:14 ----------

This is what i needed to here "That's why it has to stay in. Coolrunner sends the pulse to cause the system glitch that allows Xell in the first place. Without that glitch, anything flashed to the NAND other than the original MS dashboard will be rejected by the system"
this is the point about it being an eeprom and stuff and that any patches that are requiring the glitcher to be in place could be erased... but i guess once again the inquisitive mind is wrong

---------- Post added at 09:20 ---------- Previous post was at 09:17 ----------

"Without that glitch, anything flashed to the NAND other than the original MS dashboard will be rejected by the system" this part... and sorry about the excessive posting for some reason my computer hates me and is only letting me do so much :/ ... sh*tty school laptop

thank you... thats EXACTLY what i needed to hear.. i assumer by the way u answered my ? u understood it... in that way It makes sense in theory but just not possible ... sadface :( but The glitch seems better than jtag as it can exploit any kernel and this is a giant plus to being on xbox live and updating :))

holy moly man that was a lot of typing lol.........there's a lot to take in I guess no matter who u r....
I'm looking forward to the ability to have the dual boot tbh......XBL and homebrew...interesting ;)

indeed i ordered and nand x and coolrunner as i have 512 and lpt is not fun with that, but then DB comes out and im thinking bahh i want it but now i have to buy a DB nand but i thought there werent any for the 512mB only 16mb with cygnos... or am i wrong?:(

nand-x and coolrunner is all I'm interested in tbh at the moment lol.....
wow - could u imagine sitting there with 512 and an LPT......I'd probably rather cut off a nut lol

as for the DB function........I think you'll find TX have it covered ;) just wait and see :D

I tried to read your post but it hurt my eyes and head between alternate lines.

You say you understand, then by reply you don't.

If you have the intellect to digest the information, it's all in the reset glitch 1.1 documentation. Please read it. If you have and you're posting questions like you are, you DON'T understand.

Comprende?

Mentioning 512MB Read/Write, you only need to dump the 1st 2MB or so:

nandpro lpt: -r512 small_dump.bin 0 60

You could dump more but it's not necessary.

Once you flash the .ecc file and boot into XeLL, you can dump the remainder of the NAND via http and then rebuild the NAND:

nandpro fulldump.bin: -w512 small_dump.bin

Then you will have a full 512MB dump in a lot less time.

Yes i understand, i think i just worded it wrong alot, and alright ill just use the nand x, as the LPT i used to read the whole nand, took.... 5....days.... haha

---------- Post added at 11:29 ---------- Previous post was at 11:27 ----------

just realize it hard to make a perfect post ya ive read the technical read out since it was released... i havent seen the 1.1 though will have to..

The 1.1 release was really to support Falcons, but the tech explanation is the same.

Well usb to Jtag cable would cost me another $50 so I will be over $100
If you're planning on purchasing an Xecuter Coolrunner mate then I wouldn't go off buying a general jtag usb cable just yet. Wait to see what cable TX release, I'm sure it won't be $50.

If you are not buying the TX Coolrunner then ignore me :)

I am buying the coolrunner it is on pre order from modchip.ca. The cable I am pretty sure is 6 pins just need it to go to usb, that's why it is $50 but I have someone looking into getting one like it for cheaper price
