If you are doing restore to finish factory IMEI unlock you need to insert non-supported Sim card in i Phone first. Also you can use this guide for all times and all version if nothing change.

UPDATE #1: Did you try to update to i OS 5 and getting error 3004? If you have upgraded your i Phone’s modem firmware or baseband to version 6.15.00, you will notice that you are not be able to restore to the stock firmware (IPSW) via i Tunes.The difference between updating and restoration is when you restore the device to factory settings” (clean system), all user data will be deleted. If your device is jailbroken and running i OS 6.1.2 and you need restore but don’t want to lose jailbreak you can use i LEX RAT to restore i Phone and keep evasi0n jailbreak. Click Shift Restore for Windows (for Mac Alt Restore). But if your i Phone is jailbroken this method will not work, you’ll get stuck on the Apple logo and have to use i Tunes to restore it. Or click update button in i Tunes, specially do it for i OS 6.1.2 evasi0n jailbreak or go to Settings – General – Software update.Recovery is usually carried out at: Important NEVER update jailbroken devices! If you restored or updated i Phone and preserved, then you can use tool you used before (Ultrasn0w or Gevey or any other solution that relies on the baseband).If the IMEI field is blank, your i Phone has hardware issues and you are better off bringing it to an Apple Store for repair.If the issue is with your computer or a laptop/notebook you should try using the Reimage Plus Software which can scan the repositories and replace corrupt and missing files.In this guide, we will take you through the step by step procedure to jailbreak i Phone running i OS 5.0.1 without updating the baseband using Redsn0w.

Here are some important points to note before you proceed. Step 2: You need to download the i OS 5.0.1 firmware file (use Firefox or Chrome to download the firmware file instead of using Internet Explorer or Safari): i OS 5 firmware file for i Phone 4 from this link (i Phone3,1_5.0.1_9A405_Restore.ipsw) i OS 5 firmware file for i Phone 3GS from this link (i Phone2,1_5.0.1_9A405_Restore.ipsw) Step 3: Double click the Redsn0w zip file and extract the application to the Redsn0w folder.

Often, this leads to “Connect your device to i Tunes” issue (Recovery Mode, i Tunes icon on the screen). First enter DFU mode and only then begin the process in i Tunes. Now choose to Backup your i Phone to not loose your data like photos, songs, docs, etc. Holding the Shift key on your keyboard, click the Restore button (for Mac, press Alt Restore). In the window that appears, select the IPSW firmware loaded in step 2 and click Open. Download the latest official firmware (IPSW-file) for your device. But if you didn’t preserve the baseband you can choose factory unlock for your device.

NEVER restore or update to the official i OS firmware the locked i Phone that unlocked by Gevey Sim or Ultrasn0w tool. The restore process begins so don’t interrupt the process and wait for the end. First you need to activate your i Phone with Sim card of the carrier your i Phone is locked and only then you can use IMEI unlocking service.

Among these error messages, the “This i Phone could not be restored due to an unknown error (-1)” error is probably one of the hardest to fix because this error is said to be caused by hardware issues on your i Phone.

Specifically, this error is somewhat related to a corrupted baseband chip and it usually comes up towards the end of the restore process when i Tunes is updating the baseband of your i Phone.

It would seem that it may be nothing easier than restoring i Phone from i Tunes. And so, in this article I’ll describe the processes of restoration and renovation of any i OS devices (i Phone, i Pad or i Pod Touch) to i OS 6.1.2 and without updating to i OS 6.1.3 in the future to keep jailbreak. If your i Phone is not jailbroken you restore i Phone without i OS updating.
