How to fix some mysterious problems.

I've searched extensively on Google on how to rectify this error and all of them say the same thing, that is remove the line in the hosts file.

I've tried many times, but the line keeps appearing (I guess iTunes is editing it). And I still get that error.

I also don't know for what reason can I not do "erase iPhone". It keeps hanging and giving those spinning circles.

I also tried TinyUmbrella. I started the server and I get a different error from iTunes (error 21).

Please help me erase my iPhone. (I don't want to go to 6.1.3)

SHSH blobs work only with certain devices and certain firmwares. Unfortunately, iPhone 5 on 6.1.2 is not one of them. The only supported restore option for an iPhone 5 is to a currently signed firmware; 6.1.2 is not signed anymore so you are out of luck.

You have 2 choices: - restore it to 6.1.3, be unjailbroken for an indeterminate amount of time (possibly forever). - try to accomplish what you want using a less destructive method.

Why exactly do you want to "erase" your iPhone?

It is causing certain problems. I would prefer it be erased. I thought Apple always signs one FW less than the most latest. So, shouldn't 6.1.2 still be signed from Apple?

No, they pretty much instantly disallow all previous versions when a new one is released. Perhaps you could, instead of erasing, do an iTunes data restore from a date previous to when the problems started. Also see ml05019's suggestion

If you want to erase your iPhone, you can restore an empty backup on it. To create an empty backup, get another iOS device, restore it, set up "As new", make a backup. Note that if you create that backup on a device with iOS 6.1.3 on it, you won't be able to restore it onto a iOS 6.1.2 device.

To do this you would need an iPhone 3G or earlier; or an older iPod Touch; or first generation iPad; since those devices' latest firmware is less than 6.1.2 you would be able to restore one of those and make the empty backup file.

Interesting option. But can why can't I simply erase from my iPhone? Any ideas as to why such hiccups? With iTunes, all your answers must be valid.

Because when you jailbreak the device, some of the system files and applications get moved to a different location. When you run "erase all content and settings" it doesn't work properly and instead breaks the operating system because it expects files to be located somewhere other than where they are. By the way, this is the same exact answer as for the question "Why can't I do an over-the-air upgrade of iOS on a jailbroken device?"

regarding this - "To do this you would need an iPhone 3G or earlier; or an older iPod Touch; or first generation iPad". You may also use any device that can use SHSHs, such as iPhone 4, iPT3G, iPT4G, iPad 2. You can even use someone else's backup, maybe someone of this community can upload theirs. I used to have such a backup muself but I've deleted it when I needed disk space, so, sorry :)
