I bought an iphone that was passcode locked and find my iphone turned off. It booted fine to the password screen. I put it in recovery mode and neither of the computers I used will recognize the phone. If i put it in DFU mode itunes will see the phone. It will extract the software, but as soon as it reboots the phone to start the process, the phone won’t turn on. After a while i get a 4005 error. Help! It won’t even boot to the lock screen anymore.
try disconnecting everything apart from the charge port and battery then put through iTunes, if it still errors then try hanging in a new charge port and battery then iTunes again, if it wont flash with everything disconnected then you have a component failure.
For your problem, it is suggested that you try Joyoshare UltFix. It offers a standard mode to rectify the error code 4005 without data loss and gives an advanced mode to remove the passcode from your iPhone.
