If you have a MediaTek Android phone and have lost access to network by not being able to make or receive calls and you can see “Invalid IMEI” notification on the status bar, that means your phone has most probably lost or malformed NVRAM. But you can fix this.
This method is only possible if you have had a full nandroid backup of your phone prior to loosing NVRAM (by whatever means e.g. by formatting). Nandroid backup would also have backed up your phone’s NVRAM in an nvram.bin file which you can use to restore your phone’s NVRAM as it will fix the Invalid IMEI problem. But if you don’t have such a backup, you can still recover from the issue by following another Method 2.
However, this method involves flashing with SP Flash Tool, so you must have MTK PreLoader driver installed on your computer prior to flash with SP Flash Too.
Steps:
It should take only a few seconds to flash NVRAM. That’s it. On completion, disconnect the phone and boot it up. It should now work fine with no IMEI issue. You can watch video demo below to understand if you got any problem with above steps.
