I added the 4.1.0 link to the pastebin and snipurl, but they still need a matching 4.1.0 kernel to go with them.

Maybe give them the link to your kernel extractor script?

I've already PM'd Solaris on how to extract the kernels.

It would be much simpler - and safer - to "extract" the kernel from the official 4.1.0 update.bin using kindletool This is the only way to ensure that future upgrades will work smoothly.

Explanation: While it is possible to determine the size of the actual "required" kernel image, the kernels bundled in update files are usually padded with 0xFF bytes up to some boundary (IIRC, that's *usually*, but not always, the next multiple of 0x400). And, all the updates I've seen so far check for MD5 sums of the installed kernel (*including* the padding) to verify that the device is in a "known good" state, before performing the update. If you now flash a kernel obtained using the getkernels tool, that kernel *might* actually be shorter than what the update file provides, resulting in some of the "padding" bytes not being overwritten. And if you're out of luck, the next update will fail to install, because the md5sum of "kernel+padding" on the device does not match the expected one. I've seen it happen.

Good point, ixtab.

I've uploaded the main kernel extracted from the official 4.1 update to the same location as the root filesystem image.

The pastebin and snipurl now contain both the 4.1.0 kernel and main partition URLs. Thanks for providing those URLs. I added a note that the black K4 needs at least version 4.1.0.

I suppose the getkernels tool should add 0xFF padding to match what the updates use. It may need to be updated to support that.

I added your your K4B (black) debricking success report to the list in the simple debricking sticky thread first post.

P.S. All K4s are Non-Touch, so the NT in "K4NT" is not useful. It is just a K4 (or K4B for a black K4 when you need to distinguish it from a silver K4).

First I wanted to greet everyone. I see you guys are awsome and you realy help people out.

I have perhaps stupid question but, where can I find this pastebin mentioned above? I've just purchased K4B and I'm gathering the knowledge to unbrick it.

Cheers

I've just flashed & registered my black demo Kindle from ebay.
Thanks to everybody who made this possible.

Added to "the list". Thanks.

Some silver K4 demos do not successfully register after debricking. It is good to know that your black K4 demo registered successfully...
