The script may need updating to include B023... Thanks for bringing that up...
In mntus.params (inside data.tar.gz), change this:
"B00E" ) MNTUS_PART_SIZE=1423352 ;; # K4 (mini)
"B00E"|"B023" ) MNTUS_PART_SIZE=1423352 ;; # K4 (mini)
You do not need to use that RUNME.sh script or data.tar.gz to use MfgTool and the custom uboots. Although MfgTool is still useful for debricking (or booting demo kindles to diags mode), a better way to jailbreak a working K4 may be to use NiLuJe's K4 jailbreak:
