I've been reading posts here and there. Information that perhaps contradicts itself? Not sure.
FYI - Kindle PW5 on 5.14.2 (Jailbroken), I've used RenameOTABin (KUAL extension), I have the otaupd.bck and otav3.bck in /usr/bin/
I saw somewhere that Jailbreak withstands one update, no problem? But I'm also reading in another post, a more recent
post, saying to not update and stay in Aeroplane mode.
EDIT:
Just for further information, my Kindle's 'Update Your Kindle' button
is greyed out
