Physical Extraction - Spreadtrum

This method provides the possibility to create a physical dump of internal memory from devices with a Spreadtrum chipset without knowing the passcode or pattern lock.

SPD Bootloader mode is used for data extraction.

Spreadtrum chipsets are manufactured by UNISOC.

SPD Bootloader mode is a special mode supported by devices with Spreadtrum chipset. The device can be put in SPD bootloader mode by key combinations or via test points.

In some cases, the physical dump may be encrypted.

HOW TO

On the main screen, select “Security bypassing”.
Choose a security bypassing approach.

By model

This is the best option as you will know immediately if your device is supported or not. Also, if supported and test points have to be used to get the device into Spreadtrum download mode, you will be presented with a graphical image showing the location of the test points.

Select the exact device model from the list and choose “Get physical dump from Spreadtrum”. Follow the on-screen instructions. If your device is not listed, try another approach.

By chipset

If the device is not recognised by model and the chipset is known, use this option and select it from the list. Then follow the on-screen instructions.

In cases where the specific chipset has multiple variants, try one at a time or you can try all. The variants for each chipset are shown on the left side is a list of devices for a given variant. We first recommend choosing variants for similar types of phones however, it is safe to try all variants and it has been known that a variant for a particular device has worked and gained access for a physical image where a phone/chipset was not listed as supported.

Generic profile

Use this option if By model or By chipset has not been successful. Follow the on-screen instructions.

For this approach, you will need to search the internet for the device FW and create a PAC file which can then be loaded into MOBILedit Forensic.

There are videos online that show how to create a PAC file, you can find them on YouTube, Vimeo or other sources.
