Black Screen DFU iPhone 4, Error 1601/1602 on Restore
I have an iPhone 4 that is stuck in DFU mode and will not restore through iTunes. The following are the processes I've tried to get the iPhone 4 to restore. All are performed with firewalls turned off.
Restore Process 1
1. Backup hosts file. Do not replace.
2. Use iReb to enter Pwned DFU.
3. iTunes restore 5.1.1.
RESULT: 1602
Restore Process 2
1. Create custom 5.1.1 IPSW using redsn0w
2. Enter Pwned DFU using redsn0w
3. Shift-click restore to custom in iTunes
RESULT: Hangs up on "verifying with Apple" 1602
Restore Process 3
1. Insert "74.208.10.249 gs.apple.com" in hosts file
2. Enter Pwned state with redsn0w
3. Shift-click restore to custom in iTunes
Result: Hang up on "verifying with Apple" 1602
Restore Process 4
1. Put phone into normal DFU mode
2. Normal iTunes restore
Result: Hang up on "verifying with Apple" 1602
Restore Process 5
1. Remove hosts file.
2. Enter recovery mode (screen is black, so I'm not sure of recovery vs. dfu)
3. Normal iTunes restore
RESULT: Hang up on "verifying with Apple" 1602
Restore Process 6
1. Create custom 5.1.1 IPSW using sn0wbreeze
2. Start TSS Server in tinyUmbrella and select Upgrade iPhone 4 baseband
3. Enter Pwned DFU with iReb
4. Custom restore from sn0wbreeze using iTunes
RESULT: Hang up on "preparing iPhone for restore" 1601
I also tested the battery voltage at 3.8 volts. Any ideas?
is your phone currently on 5.1.1?

Not sure. It came to me in this horrible condition.
