Need firmware update

[Jefri91]

It worked, but I just realised I need to find a way to do system update from 4.4.4 to something higher. When I do it from "System Update" option it tells me it cannot be found

You should be doing it from the recovery menu by holding down the power button for like 15secs
Make sure your file has the correct name and stored in the root of the sd or usb

Plus the highest I've seen on these units is 5.1.1 ... honestly I had all the headaches to start with, my unit came with really buggy software. Just keep flashing software unitll you find what works for you

Also according to the link provided to you , you need a higer mcu version for 5.1.1 kld5 version 2.97 upward it looks as though mtcc is basically 5.1.1 sorry I can't be more accurate as I did mine over a year ago
