Hello,
The title has the tldr version of my situation. I used WinterBreak to jailbreak, applied the hotfix, installed mrpi, installed Update_KUALBooklet_c6ac782_install.bin, ran ;log mrpi, but get the white screen. I see the KUAL FAQ says I could get a white screen and to use coplate's version, which I did.

Is a reset of the PW in order or does someone know another way to resolve this?

Thanks for any help,
Doug

After putting the "*-k4-*.bin" file into root folder and doing a restart everything is working fine again.

I was too quick to write here. After installing the certs and also reinstalling updated KUAL from NiLuJe's first post, it's possbilbe to start KUAL for only a couple of hours. After that I get the error again.
How to make the cert-update permanent?

I just downgraded my KT11 (serial number starting with G092) to 5.16.2.1.1 for armel instead of armhf. When I try to install linkss via MRPI I get "Really failed to remount rootfs RO A reboot is recommended". After a reboot and a reinstall I get the same error and the linkss folder is not created on /mnt/us afterwards. Any assistance would be appreciated.

@Gruztn By registering it to an Amazon account? Or by keeping the device always in airplane mode.
IIRC there were report made by other people about DevCerts / MKK getting cleared on unregistered older Kindle models when device gets online and registering fixed that problem.

The device is registered to an Amazon account, and I need Wifi.

Hi there I'm a newbie to Kindles (never had one til given an old DXG) but knew they ran on Linux. Been jailbreaking then installing Launchpad and Kual by following this. But on trying to open Kual get the "The title is not signed by a registered developer" error.
Like others I'm dropping the .dxg file into root and updating the Kindle DXG and sadly still getting the same message. Any advice gratefully received!

For some reason, the latest KUAL version and/or the keystore update are broken on DXG (and on the other 2nd-gen Kindles).

The previous version of KUAL stopped working because the old keystore expired. You can get around that just by having your Kindle's clock set to a date before it expired.

The old keystore is included in the MKK installer. You should install just that and not the DevCerts update.

Here's a download link for an old version of KUAL that should work:

Hi Spartan-Heavy, sorry for radio silence... looking at kindle-mkk-20141129-r18833.tar it only has a directory called Dev Certs - can you please point me to the MKK installer keystore you mean ...

btw. I installed the update_setdate_B009_dxg.bin via root on the kindle - that's a mistake, no, given what you say above about making sure the clock isn't up to date (screenshots of current dxg file creation/modificaiton dates), but again not so sure how to set the clock without connecting to wifi...
best and many thanks for your generosity and help to all!

I meant the .bin file. Update_mkk-20141129-dxg-B009_install.bin

Copy it to your Kindle and use the "update your kindle" option. That installs the old keystore on your Kindle.

That file should have set your Kindle's clock to July 2024, which is before the keystore expired.

You can check the clock by entering @time in the search bar on the Kindle.

Having the same problem as a lot of other people on this thread.

I had the "KUAL permissions have expired" problem, which I understand to be due to expired certificates.

I updated the DevCerts from the binary in https://www.mobileread.com/forums/sh...postcount=1295, which I now understand will not work properly on my Kindle DX Graphite. I now get the error "The title is not signed by a registered developer."

If I understand correctly, the only answer to the original problem is to reset the clock to a time before the certs expired. I'm not sure I want to do that, it's going to play havoc with the "most recent" dates in my documents.

But first, how do I undo the DevCerts update to get back to where I was at the beginning?

I forgot that, first, I updated to KUAL 2.7.37, which is when I started getting the error "The title is not signed by a registered developer."

Then I tried to updated the DevCerts, to no effect.

I have now reverted to KUAL 2.7.29, my original version, but the "The title is not signed by a registered developer" error persists.

How do I revert the DevCerts changes?

Also having the same problem on my K4 trying to run KUAL... i manage to get it to work through the following process:

- flash new firmware through Kubrick
- update k4 to 4.1.4
- install jailbreak
- install mkk (Update_mkk-20141129-k4-ALL_install.bin
- install mkk (Update_mkk-20250419-k4-ALL_keystore-install.bin
- add KUAL-KDK-1.0.azw2 to documents (KUAL v2.7.37, i think it's the latest)

after these step KUAL is working fine. As soon as I connect to wifi i get "This device is not authorised..." even after trying to rename `/etc/uks` to e.g. `/etc/uks.disabled` as it is stated on the wiki to prevent updates. also placing a folder in the root directory (forget the exact naming of the folder) didn't help.

After reading a little in this thread about the kindle's clock I think it might be that the Kindle updates the clock after getting internet connection, thus rendering the cert useless.
Also i read that disconnecting from wifi and restarting or reinstalling mkk should fix it again, which is NOT the case for me. The only fix that works reliably for me is to completely flash a new firmware and redo the whole process above. (probably again because the clock resets, idk I am a noob).

This is really frustrating, cause I would love to be able to use KUAL for my project, which requires the Kindle to be connected to wifi for image polling.

If anyone knows what I need to do in order to finally fix this, PLEASE help, cause I am going crazy. (already flashed it 8 times now, thanks Kurbrick tho).
