PW, FW 5.6.1.1, winter break, coplate's KUAL, white screen

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

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?

Question Can't install linkss on 5.16.2.1.1

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:
