(help) UMI eMAX NVRAM fix

JAlejandroM

Hello
I have my UMI eMAX for a long time ago, is an awesome device

recently I formatted my UMI eMAX device with the SP Flash utility and the STOCK ROM

I successfully reconfigure both IMEI for the mobile network using the EngineerMode Menu -> AT command option

Unfortunately I do not know how to recover my old Wi-Fi MAC and Bluetooth MAC and every system restart I have a different Wi-Fi MAC
in my city we access to internet using hotspot service, Wi-Fi MAC address is necessary to be static cause we have MAC access security

Could anyone assist me with it?
* I add that I have already tryed with the known utilities for the procedure, but the MT6752 SoC apparently works different than other MediaTek SoCs I think

the moderator bencebacsi in the published guide for SP Flash Tool_ mentions something about formatting the NVRAM partition, which I don't know the procedure cause is not describbed in guide
