Advanced Users: Dingleberry Jailbreak v2.1 Persists Root Access With Latest BlackBerry PlayBook OS

DingleBerry PlayBook new

The Dingleberry team just followed through with their confirmation of jailbreaking RIM’s first attempt to keep them out by patching the Samba exploit. The latest PlayBook OS 1.0.8.6067 has been jailbroken in a way using a new exploit. According to one of the devs on the Dingleberry team, @cmwdotme, this jailbreak actually has you downgrading to a previous OS than the latest OS 1.0.8.6067 using this method for setting up your own PlayBook update server.

Keep in mind this is only for advanced users but according to @cmwdotme the trick is to run the new Dingleberry v2.1 that you can find at www.dingleberry.it and:

  • before you upgrade to the latest OS 1.0.8.6067 a then Login via devuser and run /tmp/setuidgid root /bin/sh to gain root
  • Once you confirm you have root access you can then upgrade to the latest v1.0.8.6067 and you will still have root access persisting

It should be interesting to see what exploit this latest Dingleberry is using to persist the root access now that RIM has patched the Samba exploit. Let us know if you figure it out!
