Edit: 111222777
I know you can do it by doing all the permutations of 1-9999 but what is the simpler way?
If it’s a Kindle Paperwhite with a forgotten lock-screen passcode, Amazon’s supported method is to factory-reset it directly from the passcode screen:
Tap the passcode field. Enter 111222777. Tap OK. The Kindle should reset itself and remove the passcode.Important: this erases the Kindle’s locally stored content, personal information, registration, and settings. Books purchased through Amazon can generally be downloaded again after you sign back into the same Amazon account, but locally stored personal documents that aren’t backed up may be lost.

Thanks for the reset pin, got it up and running again with a 5 book cap :)
Thats ok, it was polluted with too many books, this time im going to stick with 1-3 books at a time before I can swap them for new ones. Too many choices
