Click the bottom-left corner of the screen and then click Setup. Enter your password.

Now click System, then Maintenance, then Upgrade. Click Select File.

If the USB stick does not appear, swap the USB stick and USB mouse around.

Now choose the file: QV5152 - D315X(5.0-NAND)_128M_ELECTUS(CONCORD)_V8.2.1.2-20220304_2322_8110.tar.gz
