I'm also having issues, similar to above, but I am using the latest versions of MRPI and Kual (copilot) (31/10). I _think_ I'm doing everything right, but obviously missing something as the logs say the firmware isn't supported.
Code:

[2023-11-01 @ 09:26:02 +0000] :: [MRPI r19292] - Beginning the processing of package 'Update_KUALBooklet_d0eb25b_install.bin' (KUALBooklet d0eb25b I) . . .
Package 'Update_KUALBooklet_d0eb25b_install.bin' (KUALBooklet d0eb25b I) is not targeting your FW version [!(1679530004 < 05392502 < 18446744073709551615)] skipping . . . :(
I have a Kindle 10th (which I believe is a Paperwhite 4th?), running 5.15.1.1 after following the language break Jailbreak (which is showing Jailbreak successfully on reboot).
What are the next steps/is there anything additional that would be helpful to figure this out?
