This issue is mostly caused by wiping / corruption of the Secro and NVRAM (or NVDATA) partition(s). Quite a number of MTK users have been having this issue on their MTK devices after flashing one ROM or another. This is because your Baseband, IMEI, WiFi & Bluetooth addresses are important for radio communication. The issue generally happens when you install a custom ROM, update your Android device, or manually modify the IMEI.Ī null IMEI or unknown Baseband could make your phone unable to detect SIM Card(s), network signals (Emergency Mode), make calls or dial shortcodes (to check your account balance, etc). The Invalid IMEI is a common problem that mostly occurs in Mediatek based Android smartphones, including Xiaomi Redmi, Micromax, Oppo, Samsung, Vivo, HTC, Sony, etc. Problem with Unknown Baseband, NULL or Invalid IMEI & SIM / Network not detected
