Hi all, I'm a new user
I've bought a used iPhone which is stuck in recovery mode (iTunes logo and data cable screen on iPhone). Previous owner said to me he tried to upgrade from 1.1.4 to latest firmware but it did not work.
Now I tell you what I've done. I used a Mac with OS X 10.4.11 and a PC with Vista Business 32bit. When you'll read Mac, I used my Mac, whe you'll read PC I used my PC.
1) I've tried to downgrade to 1.1.4 again, to 1.1.2 and to 1.0.2 but with iTunes 7.7.1 (MAC) I got unknown error (1600). I downgraded to iTunes 7.5 and 7.4 (both Mac and PC) but my iPhone stays on "Waiting for iPhone" with Apple logo and Apple cursor (I mean the tipical icon which rotates, I don't know its exact name) on my iPhone.
2) I've also tried to disconnect from USB cable my iPhone after 15-20 mins like I've read on other sites, and tried again restoring it but it freezes on "Preparing iPhone" (I mean previous "Waiting for iPhone" stage on iTunes).
3) I've tried to force it in Normal mode with ZiPhone (PC) but it didn't work.
4) I've used iBrickr (PC) which gave me 2 options: Boot the phone and Downgrade to 1.0.2. The first one turns my iPhone screen green, and told me I've to use iTunes to restore iPhone; the second one put my iPhone with blank white screen, then told me using iTunes to restore but as I've already wrote above I had "Waiting for iPhone" problem.
5) I've tried iPhuc but no solutions.
6) I've tried iFuntastic, to force Recovery Mode exit, it downloaded 1.0.2 firmware, it did all the necessary but stays about 30sec on "Waiting for Normal mode" without success.
7) I've tried to use iNdependence but all buttons are grey and status said "Disconnected: waiting for iPhone".
8) I've followed this guide:
iClarified - iPhone - How to Unlock/Jailbreak Your 2.0.x 2G iPhone (Mac) [Updated] but it didn't ask to me for bootloaders and when I'll have to put my iPhone in DFU mode I cannot do that because my iPhone reboots itself in recovery mode before those 5/10 sec expired (I hope you understand what I've said).
Please help me I'm desperate and noob with iPhone. Sorry for my english mistakes, I'm Italian.
