I would like some advise on a situation I am in. I sold an AppleTV 2nd gen on eBay. It had OS version 5.3, so it was jail breakable and thus more valuable. I took photos before sending to prove this. The buyer claims the remote doesn't work and he can't jailbreak it, and thus wants a refund. He also updated the OS to 6.1 and now it's no longer jail breakable, nor is it possible to downgrade it back to 5.3. I told him he needs to send it back to me first before getting a refund. What should I do about the OS version? This buyer essentially made the item less valuable by updating it. Would it be alright to refuse the return, because it's not in the same condition? Should I refund him less $20 because he ruined the value of the item? Or should I just eat the loss?
