I hope someone can help me with this. I've been jailbreaking different versions of the iphone for years. Recovered via DFU on many occasions but I am stuck. I did purplera1n and just install cydia and then a few apps. I then installed winterboard and it asked to reboot which I said yes and I am stuck at the apple logo. If I have it plugged in via usb cable and hold both buttons down it shut down after 10 secs or so but then it comes right back online at the apple logo. If I don't have it plugged in it appears to turn off after a hard shutdown but then when I turn it on it goes to the logo. I can't go into DFU since I can't shut it down. Any ideas? Also, the one time I had brought the phone into the apple store I did a factory reset before hand. If it's indeed bricked and they can't get it to boot either is there still a way for them to know I jailbroke it? Thanks!
