I have a Samsung SCH-i535 (CDMA) that I'm trying to process with Cellebrite. I've completed a logical extraction, but am unable to process a physical. I am unable to get the phone to PDA mode using the code prompts. Anyone else had this issue and worked through it?
You can try JTAG. The process should work on SCH-i535.

Thanks for the info. I am unfamiliar with JTAG… Can you provide some info?
The Article/URL referenced above explains very well about the JTAG method.
Basically speaking, JTAG (Joint Test Action Group) is an advanced data recovery method, which is used on devices which cannot be examined via normal methods. The circumstances include, if a device was locked and you need to bypass the master lock code or/and if a device was damaged etc. JTAG is a non-destructive method, unlike it's boss Chip-Off wink It is used alot on Android/Windows devices.
During a JTAG procedure, you would solder wires to the TAP's (Test Access Ports) on the device in question. The opposite ends of the wires would be connected to the appropriate JTAG emulator, such as Riff Box. The Flash memory is then read via the Riff Box software and the raw data is extracted and can be analysed using forensic software.
You will need the appropriate equipment and also have good soldering skills!
