Invalid IMEI Solved
Invalid IMEI is a common problem faced when you install a custom ROM or update your Android device. The issue mostly occurs in Mediatek based Android smartphones. The problem causes the network to be unrecognised by the SIM card and the SIM will not show any signals or network.
Here I have come up with a couple of methods to fix the problem.
Step. 1 In MTK Engineering Mode App select MTK settings.
Step. 2 Go to connectivity and select CDS information.
Step. 3 In CDS select Radio information.
Radio Information under CDS
Step. 4 Select phone 1 and in input box enter AT+EGMR=1,7,”Your IMEI Number” and press Send AT Command. Now reboot the device.
IMEI Command
Step. 5 If you have a dual SIM device then again go to the MTK Engineering App and now select Phone 2 and enter the command AT+EMGR=1,10,”Your IMEI Number” ,send command and reboot the device.
Step. 6 Once done you will see the network.
Note: If the command doesn’t work just simply put space after AT i.e AT +EMGR instead of AT+EMGR.
Step. 1 Open the MTK tool application file and First enter the command Y and hit enter.
Step. 2 Now Enter the IMEI number and hit enter.
Step. 3 Again enter the IMEI number and hit enter.
Step. 4 Create IMEI.bak file and copy it your device storage.
Step. 5 Open the mobile uncle tool, choose IMEI Backup & restore the .bak file
Step. 6 Once done reboot the device. You will see the network again.
Note & Conclusion: Do not make any unnecessary changes in MTK App it is a very sensitive tool. ***DigitBin is not liable for any risk so do not use any other tools in MTK settings. I hope the post was helpful do comment below for any assistance required.
