Need Kindle Touch firmware 5.3.2.1 kernel
I screwed up a lot... So here’s the story:
I compiled the Kindle Touch 5.1.2 Linux kernel (linux-2.6.31, I believe), and I flashed the uImage using fastboot to my Kindle. Of course, I forgot to backup my kernel, forgot to extract and compile the initramfs, forgot about kexec, forgot that I was running 5.3.2.1, and forgot that I downloaded the source code a few months ago. Can someone send me a backup of their kernel? I’ll use it for extracting the initramfs and restoring. Use geekmaster’s getkernels script: https://www.mobileread.com/forums/sho...65&postcount=1 Thanks a lot! By the way, I also unpacked the 5.3.2.1 update file using kindletool as an effort to get the kernel, see screenshots for details. In the folder 15, there are 4 new update files following the pattern of update-15-*.bin. When extracted, each contains a file called update-kernel.tar.bz2 that in turn contains an uImage patch. I do have the 5.1.2 kernel, so any advice on how to apply these patches is appreciated. Last edited by AeroFengBlade; 04-23-2013 at 04:09 PM. |

KUBRICK it back to 5.1.2 - then update to where you screwed up.
PS: Haven't you ever heard of "netboot" (network booting untested firmware) ? |

UBoot can load executables from the network (you'll need a serial port connection to talk with UBoot). This can be a Kernel, a Kernel with an initial filesystem, or both (two images, Kernel and Filesystem). In addition, the Kernel can netboot its filesystem (note in the stock Kindle kernel cmnd line the: ip=0 argument? That turns off that feature.) Step-by-step directions? Still way down on my to-do list. Maybe someone else will write it up before I get around to it. |

I'm grateful for all the work and explanations you and many others have given to the Kindle projects.
Thank you. maybe I'll even look into this further sometime... |
