What is NOR memory? How can I find it in my iPhone?
NOR flash is used by iPhone's baseband. This is actually the flash chip for booting up the application processor. NOR can be accessed by using a kernel hack or patched version of iBoot.
S-Gold NORDumper - the iPhone Dev Team's NOR memory dumper. Extract the contents from the S-Gold2's NOR memory. Used strictly for analysis and development purposes. S-Gold 2 is the baseband chipset used on iPhone 2G devices. It's also known as baseband chip PMB8876.NORDumper Features:
- dump NOR memory in the bootloader interactive mode (S Gold 2 baseband)
- dump bootloader
- dump the main code
- dump eeprom information
How to Dump iPhone Baseband NOR Memory using NORDumper binaryStep 1: Install openssh (standard Cydia package) and wget (add http://cydia.myrepospace.com/etgamingx/ repo to your Cydia sources) pachages from Cydia. (you could also use MobileTerminal or any other SSH software) Step 2: Login into your iPhone and navigate to /usr/bin/ directory
cd /usr/bin/Step 3: Download NORDumper using following command
wget /scripts/NORDumper.tarStep 4: Extract the bin file from archive:
tar xvf NORDumper.tarStep 5: set the executable flag to NORDumper with chmod command:
chmod +x /usr/bin/NORDumperStep 6: We are almost done. Now you have to make some changes to com.apple.CommCenter.plist file in order to dump the memory. Just enter this command in terminal:
nano /System/Library/LaunchDaemons/com.apple.CommCenter.plistEnd enter the following files your file
NOTE: Remember to remove the Disabled key from your com.apple.CommCenter.plist file after dumping the NOR, then reboot, otherwise you won't be getting any calls. Step 7: Reboot you iPhone. You can manually reboot or as soon as we are using the terminal we can execute reboot process by entering
rebootStep 8: Now here is the time to launch our binary file and dump that S-Gold baseband
./NORDumper dump.binIf everything from the previous setup steps is okay you should see ......... Don't touch your iPhone while the dump file is writting. Here is the question I've found online about baseband dumping process. Question: I know this is possibly the most time consuming step of the entire (some waiting as long as 30-40mins for this step to complete) and i'm just wondering, what does this "NORdumper" really do? i understand that it is "dumping" something into the file that we are creating "dump.bin" but besides the dump, is there any munipulation happening? Are we writing information into the phone while the dump is taking place? Or is this process strictly dumping the information from the sgold2 chip inside the phone?
- Software unlock with ultrasn0w package from Cydia.
- Hardware unlock (the first iPhone unlock developed by GeoHot). Designed for iPhone 2G.
- Unlock with help of SIM cards aka Gevey SIM, Gevey Ultra, TPSim, RSim developed mostly by chinese guys. Those unlock are for iPhone 4/4S which couldn't be unlocked by any software methods right now.
- The iPhone NCK unlock method. This method is imposible unless you dump the iPhone baseband. There is a nice software from Dev Team called iPhone NORDumper. It can dump iPhone 2 baseband memory into the binary file.
wget /scripts/dump.binExamples: Modified com.apple.CommCenter.plist file
Remember another way to Dump the iPhone Baseband is to use OpeniBoot Software from Cydia. I am going to release the short guide soon. NORDumper, hnor, norz and speedynor (the other iPhone baseband dumping tools by Zibri and other iPhone Elite Members) all give the same results when dumping the NOR Resources: NOR Flash Chip: theiphonewiki info
