How can I fix an “Invalid IMEI” error on my same old phone that has faced a factory reset recently? I am using an Android 2.2.1 version phone with a CPU chip Media Tek MTK6516 416MH. I have to see this pop-up whenever I want to use the caller-interface. Please suggest me a solution.
Invalid IMEI Error Shows up After Factory Reset
Well, there is a solution to this, but it is a little risky for your handset, as tampering with live IMEIs is against the law. You need to “root” your phone. If you are sure to do this, please follow the steps mentioned below:
Using Root Explorer, replace the .modem.img from the archive to the .modem.img to the path: /etc/firmware/.modem.img
Change the permissions for the .modem.img file to both read and write.
Restart the phone and go to the location where IMEIs are usually stored: /data/nvram/md/NVRAM/NVD_IMEI/MP0B_001. And then, replace it with the temporary IMEI file located in the archive. But make sure that you discover the original IMEI (the one before the factory reset) soon enough.
