If you have formatted your MediaTek (MTK) MT6765-powered device (such as various Tecno, Infinix, or Xiaomi models) and are now facing severe network issues, "Invalid IMEI," or "NVRAM Warning" errors, you have likely damaged the device's NVRAM partition.

Disconnect the USB cable and hold down the button to boot the device normally. Safety Guidelines and Disclaimer

The "NVRAM Database File" or "Modem File" acts as a reference for your modem software to read the hardware configuration. If you have "Invalid IMEI" or permanent "No Signal" issues, flashing a valid NVRAM dump can fix these issues by restoring the baseband configurations. Download MT6765 NVRAM Database File Free
