If you own an older smartphone or tablet powered by the MediaTek MT6572 chipset, you may have encountered a frustrating problem: "Invalid IMEI" or "Null IMEI" after flashing a custom ROM, performing a factory reset, or corrupting the NVRAM partition.
If you continue to see “Invalid IMEI,” your modem firmware may be damaged, requiring a full stock firmware reflash before IMEI repair. The MT6572 may be aging, but its IMEI repair process is well-documented and reliable. Tools like SN Writer and Maui META remain the gold standard. Always back up your NVRAM partition after repairing to avoid repeating the process. Have a specific error code on your MT6572 device? Drop it in the comments below for targeted help.
