As you can see, main kernel form forensic server and from mediafire are the same. The main kernel from hostar differ from main kernel form forensic.
pastebin images are 4.0.1. Hostar's images are older 4.0.0.

Possible problem?

Nobody panic (yet), this may be a false report from the arm mkimage tool!

Code:
 $ gunzip main_kernel-5.1.0.img.gz
 $ file main_kernel-5.1.0.img
main_kernel-5.1.0.img: u-boot legacy uImage, Linux-2.6.31-rt11-lab126, Linux/ARM, OS Kernel Image (Not compressed), 5173248 bytes, Wed Apr  4 22:41:49 2012, Load Address: 0x70008000, Entry Point: 0x70008000, Header CRC: 0xD06DD1C2, Data CRC: 0x723AAEFD
 $ mkimage -l main_kernel-5.1.0.img
mkimage: ERROR: "main_kernel-5.1.0.img" has corrupted data!
That message is coming from u-boot/tools/default_image.c when it does a crc32 on the data area.
I don't see anything wrong with the code ...
(and the 64 byte header already passed the crc32 test)

Will be taking a closer look at this.
Since I want to re-use parts of the tool sources for an un-make-uImage tool.

Edit:
Theory #1 - This kernel image file was bspatched to 5.1 in the field from an earlier version and our friends at lab126 did not bother to also bspatch the crc32 checksum to match.

Hi All,

Been pointed to this thread by Silver18 in regards to help with replacing the files on a K4NT so that it is reset to factory conditions.

Firstly my Kindle isn't bricked and completely works, it has just had a screensaver hack done to it.

I was wondering if I can copy over the file mmcblk0p1.img (from K4NT 4.0.1 forensic images) to my Kindle in Windows using a normal USB transfer, and then run the following commands in Putty when in Diags mode.

(From Silver18 noobs guide)

dd if=/mnt/us/mmcblk0p1.img of=/dev/mmcblk0p1 bs=4K

followed by

rm /mnt/us/ENABLE_DIAGS
idme -d --bootmode main
reboot

Would that do it? Or are other steps needed?

Thanks

You can try it. If it does not work, then use fastboot to flash the matching 4.0.1 kernel. Beware that some have reported problems with the 4.0.1 images, so you may want to try the 4.0.0 images you can download from the second forensic images (hostar's) link in simple debricking first post.

Then you can upgrade to 4.0.1 or newer if you want. In fact, if you leave wireless on, it will probably automatically upgrade to 4.1.0...

If your Kindle was (is) running the 4.0.1 kernel now, then just re-installing the image as noted above should do it.
Otherwise, you also need to re-install a matching (main-k4-4.0.1 or whatever the matching name is) kernel also.

The reason:
These kernels use drivers and features as loadable modules, the kernel is in the kernel image but the kernel modules are in the file system image.

Grumble: It didn't have to be that way, but it was the way lab126 choose to do it.

Ok Thanks.

I doubt I can do this now then as when I replaced my original screen savers back in, I could upgrade to 4.1.

The problem now is the Kindle does not shut off ever from the screensaver. Permanently shows and image when it is off.

EXCELLENT! Previous fastboot firmware reported "Success!" status even though it failed for exactly that reason.

What you should do is read the "simple debricking" sticky, or the simplified instructions in the "small debricking guide for noobs". You can find them in the Master Index sticky in the Dev Corner Forum.

Why did you fastboot flash a main partition that is clearly documented to NOT work?

Which files did you use?
I had the same problem, if you used the 4.0.1 files.
Grab the 4.0.0 files.

Yes, I did, but you still might have the same issue, which means you need to go look at the link I gave you about undoing the ssh screensaver hack, if the runme restore doesn't work

MAJOR UPDATE: There has been a successful debricking of a K3, using the freescale AdvancedToolKit (K3 version of MfgTool)! Click the success report from qlob below for details.

There is currently a separate thread for development of K3 debricking using a similar "simple debricking" method: http://www.mobileread.com/forums/sho...d.php?t=183147
