Hi, Am on KDXG 3.2.1 (got one off ebay). I am not able to purchase games from amazon.
I think DX with 2.5.8 compat check is failing.
Is there a way around this? Spoof the version or something like that?

Yes, I got the same issue, actually I could not buy any book... I had to call Amazon customer service but finally I found I can recovery it myself... that is:

put the original system back and do factory reset then install KDXG 3.2.1 again

Thumbs up

Hi Yifanlu,

thank you very much for the asesome install package.

I could manage to install V3.3 (from my updated Kindle K3W V3.3) to my DXG by simply repacking (and signing) your update_k3w-3.1-create_updater.bin with 3.3 key.

Also nearly all the other hacks I'd tried are working after the same repack procedure.
(f.ex.: usbnet, german language pack v0.91, launchpad, fbreader, etc.)

If you also want to try it, do it with the kindle_update_tool.py - and updated V3.3 sign key included (but still at your own risk :-):
1. step: unpack .bin to .tgz with e option, then
2. step: repack .tgz to .bin with c option and --dxg suboption

Only TTS I could up to now not make working, don't know if this is a side effect, because I've not resetted my DXG before upgrading.

Greeting

DrNWM

Thanks to Yifanlu for the great install package, and to the whole community for supporting the efforts of all Kindle DXers to get the most out of their reading devices!

I would also like to "downgrade" back to 2.5.8, at least temporarily. Unfortunately, I somehow have lost the backup file, update_restore-k2-os.bin. Is there anyone in the forum that would be willing to share their copy of this file with me? I am using a Kindle DXG, and I assume that the file should also come from a graphite Kindle to be sure it will "take" correctly.

Thanks!

That would also install the 3.3 version on your k2/dx kindle. But it would "restore" the device - including a factory reset - to 3.3, not update it.
So the only concern when using the bin-file generated by your scripts is that it will factory-reset the k2/DX?

And just to double-check: to make your 3.3 script create the correct bin-file do I need to use the rootfs.img which was created by the back up script while DX was on 2.5.8 or do I need to generate a new one on my DX (which is now on 3.2.1) if I want to migrate from 3.2.1 to 3.3?

Well, technically it's neither a script nor is it from me
I've only made very minor modifications to the source provided by yifanlu to get it working with a k3 already running 3.3.

You should use the bin file from 2.5.8. It's probably possible to use newer images also, but that may need some modifications.

The package generated on the k3 is always a full recover package for the k2. You can use it for up and downgrades.
(Also be handy if you bricked the kindle. Should be usable to revover it as long as the recovery menu still works. But never needed that...)
That's also the reason it factory resets the kindle. The complete OS partition will be overwritten. It will keep books, through. They are on another partition.

update kernel on DXG with yifanlu's recovery kernel

I'm running updated DXG with yifanlu's recovery kernel and now I would like to recompile it with kexec support.

I guess I can create custom package based on prepare image from this update, but I wouldn't want to loose recovery features or brick Kindle on first try.

@yifanlu can you point me in right direction or provide recovery image for DXG with kexec if you have toolchain setup for kernel recompile handy?

@dpavlin: Yifan's writeups on this are here (building) and there (patching the update/recovery).

Seaniko7 also did some stuff with Kindle kernels, here for example.

And here's a small patch for the 3.3 kernel to at least *build* on a recent system.

If you intend to flash *everything* (kernel + modules + support files), I think any (working ) toolchain will do, but if you want to mix & match, you'll have to use something mostly matching Amazon's TC (twobob might steer you in the right direction here, he's done it ).

Is there any hope that the new K3 3.4 software can be used on the DXG? I know the update just came out today, but I thought I'd ask anyway.

You (or somebody else) would have to go through the steps yifanlu did to create the older 3.x for DX. Because of the smaller RAM in the DX, you might also have to remove some services or other memory hogs to get it to run with enough RAM left over for apps.

The new GPL source code is now available so you can build a custom linux kernel.
