# zypper install android-tools testdisk photorec

Install BusyBox on your device.

Attach your device to the computer via the USB cable, with USB debugging enabled

Check if device is connected:

$ adb devices

List of devices attached
BV6800Pro006871 device

Enter adb shell

$ adb shell

BV6800Pro:/ $

To provide adb root access to the device:

$ su

BV6800Pro:/ $ su
Permission denied

For devices with ROM that have Developer Options -> Root access, choose "ADB only" to provide adb root access to the device.
If rooted with Magisk in Settings screen switch from "Apps and ADB" to "ADB only".

Magisk v18.0

BV6800Pro:/ $ su
BV6800Pro:/ $

$ ls /dev/block
