Jailbreak ATV2 without losing photo cache

ATV2 is great but thanks to no updates boring as it can be so I want to achieve two things…

  1. get the photo cache as there are photos on it I have lost (long story) and can only get it off there
  2. jailbreak and give it some life

I’ve tried to SSH in with port 22 and the IP and Apple-TV as host with root as username and alpine as password but zero luck. Connection refused by ATV2.

So my question is this… can I jailbreak or how can I without risking losing the photo cache or how do I get it off first then jailbreak? Will Jailbreak also wipe out the photo cache?

Thank you in advance!
