How do you connect your Kindle to the internet to access OPDB/Calibre-web without losing your jailbreak?
Every time I connect my Kindle 4 to the internet, it disables developer mode and I have to rejailbreak. This is despite using an update disabler plugin (I've tested them all).
I used Winterbreak [0] and used the renameotabin extension to block updates.
It probably depends on your model, I jailbroke my paperwhite 7 (10-year old model) back in January, and it hasn't been reverted since, even though it's always connected to the internet.
