Is there any way to read the NAND to get the HDD function back without soldering to the board on the xbox? I'm not one for soldering.

No, you must solder and read the NAND.

you dont have to solder to the board...have a look at CLICK ME

I can live without it for now, dont know anyone in my area to do it for me and I dont want to pay to ship it to someone.

not sure if you saw my post since we posted at the same time, but have a look at that link

Very nice guide dude thank you!!!!

I bought one of these myself,

Looks like its the same circuit. Still waiting for it 4 weeks on

Yeah, I've been considering making a solderless connector.
We used pogo plugs for the Dish Network IRDs back in the day, but those units were actually designed so the service men could connect to them in the field.
Making a viable connector like that for the 360 is a bit more work and nothing to "latch" it down with.
I think the community would benefit in a properly designed unit, maybe I'll start working on that once I finish this jtag unit for my friend.
I've built the usb reader and installed it internally for him to use if the need every arises. I like the usb version much better.

FRICKING AWESOME! Wow. I'm ready to build this thing. Have you tried building the programmer?

This is not my guide, i sourced it from elsewhere

Hey guys, Ive seen enough info floating about about a USB flasher and how to use them but instructions on how to build them are rare. So here is a guide on how to make yours for under $30 (if you live in Australia and need to pay shipping):thumbup:.

Here is what it should look like if you follow this guide. Theres a couple of mods shown that you can do but ill come to that later.

So to start you want to get all of your parts together.

1448128 RESONATOR 12MHZ �0.27 1
1579600 PIC18F2455-I/SP 8BIT 24K FLASH �4.35 1
VAT �5.43
DELIVERY �0.00
TOTAL �5.43

maplin.co.uk
VH01B 0.1uf CAPACITOR �0.14 1
AU08J 0.22uf CAPACITOR �0.18 1
D10K 10KΩ RESISTOR �0.23 2
D100R 100Ω RESISTER �0.23 5
JP48C STRIPBOARD �3.45 1
FZ57M 0.3IN 28 PIN SOCKET �1.03 1
SUB-TOTAL �6.41
DELIVERY �2.98
TOTAL �9.39

After you have got everything in front of you, you can start cutting the tracks on the stripboard ready to solder everything in.
A couple of points.......
I have removed pins from the IC Socket (marked in RED) so there are less tracks to cut (pictured). You can cut tracks instead but that will take alot longer. To remove pins from the socket, hold the tip of your iron on the bottom of the pin while applying a little presure. The pin should just drop out easily.

There is a jumper cable linking pins 8 & 19 on the PIC that can either be connected on the front or the back of the board.

There is also a jumper linking pin 18 on the PIC to ground that needs to be connected to flash the chip (enter bootloader mode) but this must be disconnected to read or write to your nand. You can either solder two wires and connect them when needed or solder a header and use a jumper.

Notice the polarity of the capacitors. If you get polarised capacitors make sure you wire them in right.

Now look at the pictures below to see where everything goes.

R1 = 100Ω RESISTER (Brown Black Brown)
R2 = 10KΩ RESISTOR (Brown Black Orange)
R3 = 100Ω RESISTER (Brown Black Brown)
R4 = 100Ω RESISTER (Brown Black Brown)
R5 = 100Ω RESISTER (Brown Black Brown)
R6 = 100Ω RESISTER (Brown Black Brown)
R7 = 10KΩ RESISTOR (Brown Black Orange)
C1 = 0.1uf CAPACITOR
C2 = 0.22uf CAPACITOR
RZ1 = 12MHZ RESONATOR

If you wanted to make things easier for yourself, you can add an RJ45 plug on the cable that goes to the xbox, and have an RJ45 connector that can stay inside of the xbox so you don't have to open your xbox up everytime theres an update (pictured).

You can also add pin header/plugs so that you can disconnect the cable easily (also pictured).

Now that you have soldered everything together you need to flash the PIC with the bootloader. To do this, you need an additional programmer. You can build one for a couple of quid (ART2003 LVP) or if you know someone that can do it, give it to them.

If you are going to build one yourself this might help.

To build it you need 8x 1N4148 Diods, 1x 220 ohm Resister and 1x 47Uf Capascitor.

If you built the ART2003 programmer, open "WinPic800_V3_59.exe", go into hardware settings and choose the programmer. Then on the main page, set the options shown, open the hex file "PicXBoot.hex" and click the green right arrow to write the file to the PIC.

Once you have programmed the bootloader, put the PIC in your reader and connect the jumper to enter bootloader mode (remember above) then connect to a USB port. When asked to install a driver, point windows to the driver in the install folder.

After you have installed the reader, open "PDFSUSB.exe", set the board to the one pictured, load the HEX file "PICFLASH.hex" and click program device. If everything goes well you should see the same message pictured.

Now just remove the jumper and reconnect the reader to your USB port. Windows should detect and install the reader automaticly.

Connect the wires to the xbox (see picture) and your ready to read your nand.

Why don't you homebrew your xbox360 with the xell/xellous?
This is realy the best and fastest way to do it. It always works for me this way and i really did a lot.

Budreaux · Mar 15, 2010

And how did you go about writing the Xell.bin file to your nand?

wabashman · Mar 15, 2010

there are many guides on how to use xell/xellous, just google it and pick one.

Budreaux · Mar 15, 2010

I don't need to know how, I was going to make a point.
