Here I will show you how to backup and recover iPhone baseband NOR memory. This backed up file will give you info of your baseband. It is really crucial to use that data if you are trying to unlock iPhone. Using NOR memory of your iPhone baseband you can find different exploits which you can apply to unlock your phone. The program  will help you to dump NOR memory of your baseband. This program is OpeniBoot which is used to port Linux to older iDevices and you can download it here below. In case you don't know NOR is a storage medium like BIOS boot in PC. NOR seczone: This is a protected area of baseband’s NOR memory that includes encrypted data. The phone’s lock state depends on that information. This area is commonly called the NVRAM by mistake. The referring to NVRAM as the part of iPhone’s baseband is totally incorrect. The iPhone baseband doesn’t have any NVRAM, and everything (lockstate, IMEI, NCK) is stored in encrypted state in the NOR memory at the range between:

0xA03FA000 – 0xA03FC000

Here below you will see two action that help you to backup and recover NOR  memory file.

How to Dump NOR Memory (recommended)

Step 1. Download OpeniBoot using link below: Download OpeniBoot After downloading just unzip the file in the directory you've created and ensure that OpeniBoot guide is not installed on your iPhone. Step 2. Open terminal and type x: (switch to the folder where the letter), and then type: cd xxx is (to switch to the folder). Step 3. When terminal indicates your iPhone then enter Recovery Mode.

Step 7. Now type:

nor_write 0x09000000 0x0 0x100000

Step 10. Wait fore Done and type:

And that's it. Now you know how to backup NOR and use that NOR file to recover NOR. I hope it was not difficult for you but if there are some questions then let me know in the comment section below and I will help you. However I'm learning too. Remember: All you do is on your own risk because this method was tested only on my iPhone and I can't say for sure about others. And this method works only on iPhone 2G and iPhone 3G. Also there is another method to dump NOR memory of iPhone baseband, just go here and you will find out how.
