How do I install the firmware?

When switching from any other firmware, you need to wipe user data!

For stable operation of the device, it is recommended to update the MCU firmware to the current one, released in March 2021 or later.

If there is no such firmware for your device, use the latest available one.

MCU firmware can be obtained from your radio dealer or look here

MTCE versions can be installed instead of MTCD

If you have Android 10 installed:

The installation is similar to a regular firmware update:

Copy the firmware file update.zip to a USB flash drive / memory card formatted in FAT32

Connect the USB flash drive / memory card to the device

Set the "Wipe data ..." checkbox and click the "Install" button in the window that appears.

After installation, the device will automatically reboot one more time to complete the Magisk installation.

Installing from a SD memory card may take longer!

If you have Android 9, 8 or 6 installed:

Requires updating the recovery version to Android10

Simple and safe way: Use the ModInstaller Pro application (link to the application in the readme.txt file, which is located in the archive with the firmware or in my signature at the bottom of this post)

Complicated and unsafe way: look for information on this forum

Additions:

Automatic backlight control for PX5-based head units

Internet speed in status bar
