What Rockchip chipsets and Android versions are supported?

Passware Kit Mobile supports a wide range of Unisoc-based mobile devices from Blackview, Oukitel, Doogee, Umidigi, and other manufacturers.

Passware Tip: Check out the full list of supported devices on our website.

How to put Rockchip-based devices into Boot ROM mode?

Some Rockchip-based devices support various button combinations, which differ based on the device model. The options include:

1. Both volume buttons.
2. Both volume buttons + power button.
3. Volume down button only.

If none of these combinations are effective, the next option is to use test points. Typically, this involves holding DAT0 or CLK contacts. For instructions on disassembling mobile devices, visit iFixit.

From which mobile applications can data be decrypted?

In addition to passcode recovery, Passware Kit Mobile detects installed applications and either performs their instant decryption or initiates the password recovery process. The decrypted device data is typically saved in plaintext or DAR format for file-based encryption, which is compatible with most forensic tools. Application decryption results are saved as an SQLite database in the “unprotected” folder of the output project folder.

The list of supported applications is as follows:

What encryption methods are supported for Rockchip-based devices?

The following encryption methods can be used on Rockchip-based mobile devices with file-based encryption:

• Secure Startup 
  NOTE: Instant decryption is available for phones with disabled Secure Startup
• PIN, Pattern, Password

Decrypted data format is DAR or plaintext.

Passware Tip: The passcode length and symbol set can be detected by PKM automatically. Additional information is displayed on the top panel. Use it to customize the attack settings and recover the passcode faster.

Can GPU acceleration be used with Rockchip-based devices? 

For Rockchip-based devices with Secure Startup enabled, Passware Kit Mobile performs GPU-accelerated brute-force and distributed password recovery.
Once the encrypted data is extracted, the device can be disconnected from the computer running the PKM.

What happens if the computer powers off or restarts while I am brute-forcing the device password? Will I lose progress or be charged an extraction credit from my license balance?

The recovery state is automatically saved, so progress is not lost if the computer powers off or reboots. No additional extraction credit is required to resume the process as long as the same PKM Product Key is used.
To continue the passcode recovery process, launch Passware Kit Mobile again and select the project from the “Recent Projects” tab on the right pane of the start page. Passware Kit Mobile will resume the process from the most recent state. 
You can also resume the project by clicking the “Open project” button on the start screen and locating the pkm_project.pwproj file in the output project folder.
