iPhone 3G Recovery mode restore failure 1015
I have an iPhone 3G, purchased when it was first released in Australia. It was sold as Network unlocked, which I discovered a year or so later when it underwent an iOS upgrade, meant it was Jailbroken. With the network lock back in place, and the prospect of my partner not having a functional phone the next working day, the process of Jailbreaking it again to get it running back on the network. The process was successful, and the phone was kept away from further iOS upgrades for fear of rendering the phone inoperable again.
But eventually software outgrew the phone and it entered retirement.
Now it is needed again, but for someone else, and the iOS phone architecture would them well, and they have no need for the cutting edge.
According to the great resources of the internet, the phone can be restored from recovery mode, which is the state I found it in when trying to get it back into service, by plugging it into iTunes and performing a restore. The restore process does not succeed however.
The following steps happen, as listed on iTunes;
Restore iPhone Software: iTunes progress bar completes; iPhone progress bar, about 1/3
Verifying iPhone Software: iTunes progress bar completes; iPhone progress bar, about 3/5
Restore iPhone Firmware: iTunes progress bar completes; iPhone progress bar, about 2/3
Verifying iPhone Firmware: error 1015; iPhone goes back to recovery mode.
I suspect that it is having trouble with the firmware restore.
So the relevant questions are;
1. Can the iPhone 3G be recovered in a usable state?
2. Even if it is recovered, can the network lock be removed?
