Introduction Mobile devices using MediaTek (MTK) chipsets sometimes show IMEI issues after firmware flashes, ROM changes, or corrupt NVRAM. An “MTK IMEI repair tool” refers to software utilities designed to restore or rewrite an IMEI and related radio parameters on MTK-based phones. This post explains what these tools do, how they work, legitimate vs. illegitimate uses, and guidance on safety and legality.
Warning: Do not use an IMEI generator. You must restore your original IMEI (printed on your phone box/purchase receipt). Using another phone’s IMEI is a crime.
Prevention is better than cure. Before flashing any custom ROM, backup your NVRAM using MTK Droid Tools or Wwr_MTK.
Depending on your device model and the severity of the issue, you can use these software solutions: ChimeraTool
