2.1 What is NVRAM?

In the context of MediaTek (MTK) devices like the Tecno KG5k (which utilizes the MT6765 Helio P35 chipset), NVRAM refers to a protected partition on the onboard eMMC storage. It acts as the "identity vault" for the hardware.

When this data gets wiped, your phone’s radio turns off. You will see a red "X" over the signal bar.

Instead, you need an empty or generic engineering NVRAM for the KG5k.

A Healthy Backup: NVRAM is device-specific. It is always recommended to use a backup from your own device or a "clean" file from the same model. General Procedure for Restoration Preparation: Load the Scatter file into the SP Flash Tool.
