The International Mobile Equipment Identity (IMEI) is a unique 15-digit code that identifies your phone on a mobile network. A common cause of IMEI corruption is incorrect firmware flashing, which can overwrite or erase the NVRAM partition that stores the IMEI and other critical calibration data. This often results in "Invalid IMEI," "Null IMEI," or "No Service" errors, effectively preventing calls, texts, and mobile data. oppo f11 imei repair unlock tool top
