Kindle firmware 3.1

[adq]

This blog has moved I've been doing some playing about with the recent kindle 3.1 firmware release. The salient points are:

1. The jailbreak can no longer be installed because Amazon have patched the busybox tar exploit which allowed unrestricted writing to the root filing system. Keep an eye on this thread over at mobileread for information on 3.1

So if I bought a kindle now would I be able to jailbreak it before it updates or will it be forced to update as soon as I switch it on?

I'm not sure if the upgrade is pushed or not yet; certainly it wasn't to mine or Nicola's, I downloaded it and manually copied it to it for it to install. I've heard various rumours though, so I decided to err on the side of caution.

They /will/ start shipping them with 3.1 eventually though; currently Amazon say 3.1 is a "preview" release.

Forgot to mention; there's an externally accessible serial port hidden in the case which gives you access to the bootloader so you can (not tried myself yet) always hack it through that. As long as you know someone with the right hardware for it :)

Resetting?

Do you know if a manual reset uninstalls hacking upgrades?

My Kindle has 3.1 now (or even shipped with it, I'm not sure) and I haven't had any luck installing your dev keys. Any suggestions of how to get root access?

Manual reset should keep the upgrades.

I guess by now, you've found the new jailbreaks for 3.1?
