Thanks!

I was able to keep the JB of my Kindle updated to 5.12.4!

Just for reference, I report here the steps:

1. Install the most recent hotfix from here
2. Reboot the device
3. Copy the new firmware (downloaded from amazon), install it via "Update your Kindle", reboot etc.
4. Execute the recovery steps from this page (do all the required reboots)
5. Install MRPI again (maybe it's not strictly necessary, but why not), by copying it
6. Install Kual (Coplate) (Update_KUALBooklet_*_install.bin), by putting it inside the mrpackages folder and using again the ";log mrpi" command

I did not use the Update_KUALBooklet_hotfix_*_install.bin install package, which is supposed to be installed via UYK, since when I unplugged my Kindle, the UI showed a dialog about an invalid update package and it also removed the bin file!
