Recover data from an iPhone
If you have lost your data (pictures, contacts...) from your Iphone, it's still possible to recover them.
- a Jailbroken iPhone. Warning: Jailbreaking, according to Apple, voids Apple's warranty on the device.
- BSD Subsystem and OpenSSH installed on your iPhone
- Terminal (or MobileTerminal) installed on your iPhone
- An SSH server installed on your computer (Standard on Linux and MacOS X)
- The 'DD' utility installed on your computer (Pre-installed on most Linux systems)
- PhotoRec installed on your computer
- a wifi connection
- Turn off autolock on your iPhone: Settings > General > Auto-Lock > and select "Never".
- Connect the iPhone to its charger
- Start the Terminal on your iPhone
- Use "su" to become root
dd if=/dev/rdisk0 bs=4096 | ssh -C username@computer_IP 'dd of=iphone.img'
usernameby the user account on your computer and
computer_IPby the IP address of your computer.
- This command is case sensitive, don't get it wrong.
- Don't confuse
dd of=, otherwise you may overwrite your iPhone memory.
- It can take a few hours, so be patient. There will be no progress bar.
- If you want an indication of progress (dd statistics), put the job in background (Ctrl-Z, bg). Then send the USR1 signal to the dd process (kill -USR1 `pgrep dd), and it will print to stderr. For awesome points, wrap that call in a watch loop. If you're really good, you can make your own progress bar, since the numbers are all there.
- Once the copy is finished, on your computer, run
cd testdisk-6.12 ./photorec ~/iphone.img
- Follow PhotoRec Step By Step guide if needed
Note that data is encrypted by default on iPhone 4, so you need to decrypt the data first: http://code.google.com/p/iphone-dataprotection/
Fixing the partition table from image extracted using UFED
Image extracted using Cellebrite 'Universal Forensic Extraction Device' (UFED) may not contain a valid partition table, so the image isn't usable with other Forensics tools. To fix the partition table,
- run testdisk with the image name in parameter:
testdisk "Bram_Image (iPhone4GSM_5.0-5.0.1_Physical_Physical_02-12-11_12-10-17.img)"
- Select EFI GPT for the partition table type
- After Analyse and Quick Search, several HFS/HFSX partitions should be listed
- Select the first partition (it begins at sector 64), press 't' to change its type to
- On next screen, choose Write, confirm, Quit
Now the disk image can be used with almost all forensics tools.
