Yeah once you jailbreak you can replace the ota binary with a dummy and it won’t update anymore.

Personally i would not buy a kindle with the intent to jailbreak it, just buy a kobo.

The exception being if you want a scribe. There is no other 10” 300dpi ereader. I bought mine from an eBay seller who had one on the correct version and jailbreaking it was a bit anxiety inducing, given the cost and the fact I had no use for it if it were unsuccessful.
