I managed to permanently restore my IMEIs on my Xiaomi Redmi (having MTK 6589T) with SN_Write_Station_Tool, that means also after a facory reset I do not get "Invalid IMEI" again.
But so far I was not successful to restore my WIFI MAC address (and my Bluetooth address) permanently so that it will also remain after a factory reset, instead I keep on getting "NVRAM WARNING: ERR 0x.." after full wipe (after using SN_Write_Station_Tool and booting everything is fine).
: Did you try a factory reset after applying your proposed procedure and is the NVRAM warning still gone?
