Had to get creative, so, hopefully this doesn't break on old devices.

Here's a completely untested DevCerts build that *should* update your on-device keystore (and *only* that)...

Hi, recently I found my old kindle and I am starting to use it again. I had it jailbroken, with Kual installed and so on. However it wouldn't worked because of the expired certificate.

So I put this under "keys" folder in my kindle 4 NT and re-run Jailbreak Installer, kindle-MKK installer, Kual installer, but still it says that "this content is not signed by an authorized developer". What should I do? It is not clear to me.

Thanks in advance and thanks for updating things to make it work .

Can I ask how you managed to update your kindle touch? I tried the method as described by amazon with the update_kindle_5.3.2.1.bin and then following that with the update_kindle_5.3.7.3.bin but upon running 5.3.2.1.bin- it fails and cannot get any further. I have tried running rescue packs / jailbreak uninstallers to no avail though.
I even tried fastbooting and flashing it back with amazon original certs but I cannot seem to even get fastboot working through the few ways possible.

I feel quite stuck so any help would be appreciated!

Sorry for the delay.
I just used the stock firmware from Amazon for 5.3.7.3 then installed everything again (jailbreak etc).
Firmware was downloaded from Amazon site.

Did you install the DevCerts update? You should have downloaded the DevCerts zip file from here, copied the .bin installer from it to your Kindle's root directory, and then used the "update your kindle" option in the settings menu.

Also, you need to make sure that your Kindle has the latest firmware, version 4.1.4. The latest KUAL version won't work if your firmware isn't up to date.
