Hello all. I sold my iPad mini 1 on eBay and now I need to downgrade it from the PB of 8.4 to 8.3 so the buyer isnt stuck with beta software. I am currently downloading the 8.3 ipsw from here: http://www.iphonehacks.com/2015/04/download-ios-8-3.html Will this work if i just restore it to this? If I have to let the buyer know that it will be on the PB, will it be unlinked from my account and stuff? I already unenrolled it but beta 4 of 8.4 still shows up when you go to software update. What should i do??? Please help whoever can, thanks!
