Crazy DFU iPhone!

[googleuser]

Hi,

I've bought an iPhone I lived happily with until some crappy things happened.

First, the Wi-Fi was grayed out, so I tried the ZiPhone fix (I was desperate) and it didn't work. Finally, I pwned it and used an iLiberty payload which apparently fixed my Wi-Fi. But one day, the speaker started making a cracking noise, and finally the phone displayed black and white stripes, then multicolored dots and booted in and out of recovery mode at will. i tried everything! Finally, I tried to restore to 2.0 (5A347) with no luck, then to 1.0.2 and to 1.1.4. With these last two firmwares, it started restoring, until it reached the "Restoring iPhone Firmware" part where it would end with an error. I tried every iTunes version I have (7.4.2, 7.5, 7.6.2 and 7.7) without any success!

I think that the problem is the baseband, and that if I erase it the phone will finally restore.

But how do I erase the baseband when the phone is in DFU mode, and I cannot restore?

Thanks for your help!

You need to put the iPhone _into_ DFU mode to restore it. Plug the iPhone into the computer and have iTunes on, wait for it to give you any errors, and just disregard them. First, turn the phone off by holding home and sleep/wake until it shuts off. Then, hold home and sleep/wake for exactly 10 seconds (count it out in your head) then at the 10 second mark, let go of JUST the sleep/wake, but keep holding the home button until iTunes says it detected a device in recovery mode (the screen on the iPhone should be completely blank, there should be no iTunes connect or anything on it). Then restore (iTunes 7.5 for 1.1.4, or iTunes 7.7 for 2.0).
