[strongarm]

RT. Can anyone give me a hint to do so? I don't known whether A4 CPU and access basedband NOR flash memory.

I'm sorry to send my question again in this thread. It seems here are more people.

First, why "other devices" thread?
Second, why You want to dump it? Want to unlock or it is bricked? (btw, if You search google for it, will get answer as @MuscleNerd from @devteam was dump it long ago)
Third, if You still willing for procedure, follow this:
Step 1: Install openssh (standard  Cydia package) and wget (add http://cydia.myrepospace.com/etgamingx/ repo to your Cydia sources) packages from Cydia. (you could also use MobileTerminal or any other SSH software)
Step 2: Login into your iPhone and navigate to /usr/bin/ directory
Step 3: Download NORDumper using following command

Code: [Select]

wget http://www.letsunlockiphone.com/scripts/NORDumper.tarStep 4: Extract the bin file from archive:

Code: [Select]

tar xvf NORDumper.tarStep 5: set the executable flag to NORDumper with chmod command:

Code: [Select]

chmod +x /usr/bin/NORDumperNOW HOLD ON AND CHOOSE BETWEEN THOSE TWO STEPS (6a or 6b but NOT BOTH!!!). If You use 6b, skip down to step 8!!!
Step 6a: Enter following in terminal:

Code: [Select]

launchctl unload -w /System/Library/LaunchDaemons/com.apple.CommCenter.plistStep 6b: Enter this command in terminal:

Code: [Select]

nano /System/Library/LaunchDaemons/com.apple.CommCenter.plistOn the end enter the following lines to Your file:

Code: [Select]

<key>Disabled</key>
<true/>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 (in case of step 6b).

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

Code: [Select]

rebootStep 8: Now here is the time to launch our binary file and dump baseband

Code: [Select]

./NORDumper dump.bin Don’t touch your iPhone while the dump file is writting. NOTE that it can take a time to finish!
Hope this help.
