MECOOL K3 PRO REINSTALLING IMAGE PROBLEM

Hi gurus

I have a problem to reinstall my original image on mecool k3 pro from malaysk firmware to my mecool k3 pro image that came with the box. When I try to reinstall it gives me error this package is for KII PRO VSDVB DEVICES, THIS DEVICE IS A KIII PRO. Please I need your help because I can not continue with malaysk firmware since DTV does not work. I have tried to format sd card and put image there but still same error.....This package is for KII PRO VSDVB DEVICES, THIS DEVICE IS A KIII PRO. Could you give me step by step recovery process. Many thanks in advance

Have you tried the original Firmware or just your backup ?

You can try KIII_PRO_AVL6862-NHG47L-20180908.182748.V0213.img if you have the old hardware-version from 2018.

Many thanks its sorted out now
