SpIdErXeN,
here's a tip also. DONT FORMAT your onboard memory device on the XBOX settings.

if you format your memory device, you'll lose LOSE the Avatars and maybe some other important things as well. If you format , you'll get a message asking you to connect to live and says you an "UPDATE"

DONT, NO WAY, DONT

I also wonder what version MoBo I have  , box says 256meg Xbox 360,   but memory device says 322megs, and  466megs If you  decide to format  which I think would be a mistake

if anyone does format, there might be a way to re-install 7363 kernel on Jaspers so far, but i dont know if thats gonna burn any "Efuses"

I plan to make a circuit board with mini swithes for the RT63 resistor and a switch for the "grounding the NAND" to avoid access to it

first i need the LPC-H2148 USB Jtag baord ,  looking for 1 now

keep in touch

Hey bro, I actually lucked out. I remembered buying the jtag lpt adapter/connector a while back when xell was originally announced and running on xenon boards only. I think I got it for around 15 bucks on ebay if i remember correctly. I didn't know that it would take around 9-10 hours to read the nand over that thing for us though lol. If you run across one that has a usb connector, definitely let me know, I'd love to get my hands on one of those as well.

Thanks for the tip on not formatting, the "what if I format, how much space would I have?" thought actually crossed my mind last night, but luckily I didn't. lol, thank god, that'd have been a real boneheaded maneuver on my part, heh heh. I'll let you know how my efforts to xell this thing goes. Take it easy Solo, thanks for all your help so far, have a good rest of the weekend.  

[SoloStyl]

yeah bro, no problem

learning myself and helping as I can

the 256meg Jasper takes about 9-10 hours on LPT, 20+ hours for a full 512meg  

...and thats just for one NAND dump! i like to get 3-4 NAND Dumps just in case
thats why im going the USB LPC-h2148 route

it should only take 30-45 mins for the 256meg Jasper  and 1-2 hours for the 512meg Jasper

LPC-h2148 reads:
16megs in 2 mins   FULL NAND Dump 256/16*2mins = 32 mins(PC dependent)  compare 9-10 hours on LPT
16megs in 2 mins   FULL NAND Dump 512/16*2mins = 64 mins(PC dependent)  compare 20+ hours on LPT

someone already posted write speeds somewhere

[SoloStyl]

Just order my LPC-h2148 and RS-232 SMD Shifter

SparkFun   total: $64.00 US (including Shipping)

takes 3-5 buisness days to get here from FedEx

WOOT  

[SpIdErXeN]

Sweet, hell yeah! You're the man Solo! I'm gonna grab one of these as soon as I get paid. Definitely the 3-4 nand dumps are the way to go, for sure, I totally agree. Aww crap, it looks like their website is down currently. Wonder when that happened.

[SoloStyl]

im the man? lol  nah i just love all this stuff

all credits go to xbox community for sharing their knowledge

btw  did you try sparkfun? site should be up

dude i quit trying to type on this PSP    lol

going back to my Pc

UPDATE: Dec 18,2009

XbRebooter is now available for 256/512 Jaspers.
You can find what you need at "the usual places"

Thanx Go To The Entire Xbox360 Scene (you know who you are   )
We Appreciate all your hard work fellas

Oh HELL YEAH! Thanks Solo, best news I've heard all week!  

Crap...sparkfun is out of the Header board for LPC2148. >_<


Well, I believe I found them on a couple of different sites, a little more expensive, but they look the same. Solo can you please look at this one for me and verify if its the right one before I buy. Thanks a bunch bro.

http://microcontroll...roducts_id=1393

[SoloStyl]

yup, thats the one  

dont forget you still need the RS232 Shifter SMD board to be able to flash the lpc-h2148
(some use other types, but this is easier i think)

its about $14 US  http://www.sparkfun....products_id=449

I received my boards on friday so gonna get started on wiring and programming later

i did a 256meg Jasper earlier on LPT and it works great, just took forever getting orig.bin

USB is best so far for these big blocks until CygnosV? if ever its made

have you verified your CB's on your 360 2meg or 16meg NAND? dont want you to waste your cash if it cant be Jtaged you know

i found a bunch of Jaspers with Good Dash Versions, but they were 6750(un-exploitable Kernels) after a quick Nand Check

[supes]

guys I just have quick question I have a arcade manufactured october 2008.  I have no way of doing a nand dump, but is that most likely exploitable?

Ehh crap, I havent verified the CB's yet. Damn, kinda scared now. My box had the same kernel and dash version as yours though...man, I hope it's doable. I gotta call this friend of mine for some soldering help.

SpIdErXeN
supes
anyone else ....

solder 5 wires(diodes and resistors may vary) on a LPT port
dump 2-3 megs of your NAND with NandPro20b
then check your CB's etc with this:

Good luck

[SpIdErXeN]

Hey Solo, a few quick questions man, I apologize.

0. If I build the db25/printer cable with the 100ohm resistors, and the diode switch, is that enough to read the NAND, obtain my CB value, and if the CB value is good, install/flash Xell to the NAND?

1. How do I install/flash XBR/Freeboot from, or to Xell?

2. Do I need the RS232 Shifter SMD for this process if I use the db25/printer cable?

3. I believe I have a cable that has a RS232 Shifter SMD built into it. 6 wires are attached to it, each of them are labeled, (RTS, GND, CTS, RXD, VCC, and the last wire is blank with no label). I bought it when the jtag xploit originally came out. Think I can use it?

4. Also, do I plug the 6 wires from my RS232 Shifter SMD cable into the corresponding points on the LPC2148 Header Board if I buy one? Is that for flashing XRB, or freeboot to the NAND from Xell?

5. What are the points on the LPC2148 Header Board that I connect the rs232 cable's wires to when I want to flash XBR/Freeboot?

6. If I use the LPC2148 Header Board, the same one you've got, what are the points on the Jasper motherboard that I connect the wires that run from the LPC2148 to?

7. After I have the wires connected to the Jasper motherboard, do I just plug the LPC2148 into a usb port on my pc?

8. Can I run a usb cable from the LPC2148 to the 360's usb port, then from the LPC2148 to a usb port on my pc? (Kind of like connecting the 360 to my pc via usb cable with the LPC2148 in between the two. Not sure if that's possible because I havent receive the LPC2148 yet lol.)

9. Will I still need the 100ohm resistors, and the switching diode, if I have the LPC2148 Header Board?

Sorry man, I'm a n00b at this, but I'm trying hard to figure this out. I have somebody that can help with the soldering, I'm trying to get the directions down first though. I really appreciate all your help man.

[SoloStyl]

sorry i haven't replied sooner, I was dumping the Nands with the new LPC-H2148

answers:

0: yes. and you can install Xell, but dont need to. install XBR instead. it contains Xell already and you can start using homebrew
1: extract your KeyVault and then inject it to XBR.bin using nandpro. freeboot only works with dual Nands
2: No, SMD Shifter is for programming *.hex file to the LPC-H2148
3: I think so, but you have to solder the wires to the LPC-H2148 to be sure
4: yes. make sure you solder correctly(Rx,Tx, VCC,Grnd) or you can burn out the LPC-H2148 or lock it. dont forget to Ground pin0.14(Ext1 If i remember) hold the reset button, THEN plug in USB.
5:  http://img188.images...2shiftersmd.jpg
6:  http://img188.images...2shiftersmd.jpg
7: No. Dont plug in the USB UNTIL you flash the "xspiflash.hex"(its in Nandpro directory folder)
8: No. Might even damage something
9: Nope. Not needed

it was a pain in the ass for me too(got it running today finally, ITS FAST), once you get your LPC-H2148, I'll run it thru with you step by step, just be carefull or you can totally mess those boards up,and the 360

i modded my 360 too, i'll try to post pics and make a Tutorial.  lemme know when you get your board

[SpIdErXeN]

Thanks so much for all the help bro, I'm still a novice at soldering, but I'm working on it. You have really helped me out, this seemed very confusing, but I think I'm getting it now. I'm itching to crack open my 360 and do it myself. I know I probably can, but I don't want to end up frying something lol. Since I've got nearly an identical arcade unit to the ones you have, what would you say are my chances of having a CB value that isn't 6750? I'm crossing my fingers here lol.
