Afternoon,
Firstly, my sincerest appreciation for your responses to me, very thankful you're willing to help me out
I replaced the
extensions/MRInstaller/bin/mrinstaller.sh file with the one you provided and restarted the device.
I then added the
Coplate version of
KUAL (Update_KUALBooklet_f54e864_install.bin) through
MRPI, placing the file in the
mrextensions with the command
;log mrpi after ejecting and unplugging the device.
After a couple minutes, the display resets and reloads with the loading bar. Upon returning to the main screen, I use the search bar for KUAL.
There are no items returned.
The results of the log file are in untruncated form!

[2020-03-06 @ 17:09:29 -0001] :: [MRPI r$Revision$] - Beginning the processing of package 'Update_KUALBooklet_f54e864_install.bin' (KUALBooklet f54e864 I) . . .
Failed to parse package 'Update_KUALBooklet_f54e864_install.bin' (KUALBooklet f54e864 I) [return code: 126], skipping . . . 
KindleTool output:
env: can't execute '/mnt/us/extensions/MRInstaller/bin/PW2/kindletool': Permission denied
I decided to give the
UYK route a try.
This returns immediately,
Update Error: 007, then changes to
Please wait whilst your Kindle starts up
The Kindle appears to restart itself, returning to the loading bar.
The device returns to the main screen, KUAL unfortunately doesn't install.
I hope this helps one way or another
