i have a problem. i bought one of those "trade in your water damaged iphone" on ebay, and when it came in, i jailbroke it. so then a guy said he could unlock it for me, so i had him do that, and when i got it back, he said the best he could do was a "tethered" unlock. well, the battery died on me, and ever since, all i can get is the apple sign, i plug it into itunes, it gets half way through a restore, and kicks me out with "error 1015" i've tried it with or without the sim, that made no difference, tried running greenpoison and pwnagetool, that didn't help, somebody mentioned i may need to run a custom IPSW, but i have know idea what that is or how it works, i don't even care if it's jailbreaked anymore, i just want it to work. anyone have any ideas?
