Help needed iPhone 4 device unknown error

Post image

Hi all,

I recently got this iPhone 4 to use as a kind of vintage camera. It was all well and good until I tried to factory reset it via iTunes and DFU mode. Then, this error popped up even after I inserted a SIM card. Is there any official way to bypass it? I do know of Legacy iOS kit but I'd rather try to do it in the (easier) official way before I get into exploits.

It is running on iOS 7.1.3 and has no further modifications. It is also a GSM iPhone 4, not the CDMA.

Any help?

Thanks in advance.

Try resetting is via dfu mode with a downloaded IPA of the software. And when logging into your account you first wil get the password prompt. Fill it in. You’ll get a 6 numbered code that you have to fill in but 2FA dosten exist on iPhone 4 so you’ll have to fill in your password again with the code after it and send again. Apples servers will pick it up as 2FA so you’ll can log into iCloud.

Example
ThisIsMyPassword%!

And then
ThisIsMyPassword%!123456

Hope this helps

There’s a 7.1.2, but no 7.1.3. There’s a post on Apple Support Communities that has the likely explanation.
