This thread is specificly for dumping the 512mb Jasper NAND in 10 minutes, instead of 16 hours by lpt. This is how I was able to accomplish this.
Before you attempt this, you need to have Xell already installed into your NAND, a copy of gentoo livecd beta 2, burned to either a CD-R or DVD-R (i had to burn it to a DVD+R, it was the only way for my 360 to read it, and it doesn't matter if your DVDROM is flashed or not, with hacked firmware) a usb mouse, a usb keyboard, and a usb memory stick larger than 512MB formatted to FAT32. (i used a cruzier Sandisk 4gb)
The link below does have a great description on how to perform this, but the way it was written, didn't work out for me, and I had to do some things differently to accomplish this. I'd like to thank "duggyuk" from xboxhacker.net, for taking the time to go over this with me.
First you need to create the lflash.c file
How To Create lflash.c
http://forums.xbox-scene.com/index.php?sho...p;#entry4588976
Once you have created the file lflash.c, copy it onto your usb memory stick, and place the usb memory stick in the rear usb port on the 360 (i had to use an extension since the body of my memory stick was too fat to reach the port)
If your 360 is standing up, plug in your usb mouse in the left usb port, and plug in your usb keyboard into the right usb port
Eject your 360 tray, (which will turn on your 360) place the gentoo cd/dvd into your 360, now shut the 360 off.
Now, turn on the 360. After about a minute, linux should be booting up. If it seems that a certain part of linux is frozen for 5 minutes or more, power off the 360, and start again, (this is normal, usualy happens only once)
When linux has finished loading, you'll be heading into gentoo. Gentoo will first present to you a pixel looking gray screen with a mouse cursor. After a few minutes, the screen will change, and a username window will pop up. DO NOT WRITE ANYTHING IN IT! LET IT DISAPPEAR.
Continue to let gentoo do it's thing, and after another few minutes, you should be presented to a Desktop similar to Windows.
Now, for all of you that are using an HDTV and xbox 360 componet cables, you will not be able to see the top toolbar. I found this out by moving the mouse around, letting it sit, and seeing an info box pop up for some odd reason.
So, when on the gentoo desktop, move the mouse cursor to the upper left part of your screen. Wait until you see the infobox "Browse and run installed applications" when you see this, left click the mouse. (if nothing happens, move the cursor higher into the upper left corner)
A dropdown menu should appear. Goto "Accessories" then goto "Terminal"
Here is where I spent most of the time scratching my head. But hopefully you won't have to. What I'm about to paste, is what you have to type into the "Terminal". What you see pasted below is EXACTLY how your supposed to write it. Uppercase, Lowercase, Symbols, you name it, it all has to match. Pay no attention to whatever "Terminal" says when pressing Enter after certain commands, just don't worry about them. Just make sure you type everything written below correctly, and in order. just to give a heads up, when it comes time to type in the password, you won't be able to see it.
sudo passwd
su
su
cd Desktop
mkdir flash
dmesg | grep -i "SCSI device"
sudo su -
sudo passwd
su
su
mount -t vfat -o uid=gentoo,gid=users /dev/sda1 /home/gentoo/Desktop/flash
cd /home/gentoo/Desktop/flash
gcc lflash.c
chmod +x a.out
./a.out backupnand.bin
Once you press Enter after inserting the last command, gentoo should begin dumping your NAND onto your USB memory stick.
Now, I must warn you, most likely this process will freeze on you. I found out that again, this freezing is normal. It happend to me 3 times. Each time I restarted the entire process, gentoo got further into the NAND. By my 3rd time, I had a complete backup of my 512MB nand in less than 10 mins!
My 512MB Nand file size was "540,672MB"
However, when it came time for the Verifying part of the process, it froze again.
I take no responsibilty/credit for anything here. All I'm doing is letting everyone here know, that has a 512mb Jasper, my methods on how to accomplish this with little to no headaches.
Also, if it does freeze on you during the dumping process, this is what I did. I reformated my USB stick, copied the lflash.c file back onto my usb memory stick, and started all over, until I got my backup of my NAND.
谁翻译一下。 |
