It happens, you have just flashed your Phone ROM and then boom you don’t have a network connection. You can’t make a call or receive one, send a text – just about everything that requires your phone to connect to a phone mask. Reason? Invalid IMEI. There’s no need to panic this is a pretty common issue, especially for older Android phones. So how do you fix invalid IMEI after factory resetting your phone? Here’s a simple solution to help fix invalid IMEI.
How to fix invalid IMEI error after factory settings
Step 1. Check your phone’s IMEI address
Open the Settings app and go to “About phone” then “Phone status” and check under “IMEI.” If your phone is a dual SIM device, you will see two sections for IMEI – one for SIM card slot 1 and the second one for the second slot. Because your device tells you IMEI is invalid, you won’t see anything under the section. Let’s fix that.
Note: It allows you to run Advanced Setup from Engineering Mode Menu of MTK phones, also called SERVICE MODE. It only works for phones that run a MediaTek chipset.
Using this app will enable us to manually assign a new IMEI address to your device.
Step 3. Download an IMEI Generator app –
In this case we’ll use the Bb IMEI Generator app. It’s available on Google Play.
Step 4. Open the MK Engineering Mode app and go to > MTK Settings > Connectivity > CDS Information > Radio Information > Phone 1 or Phone 2
Step 5. Manually assign an IMEI to your device
After clicking on Phone 1 you’ll see a new page with an input space filled with AT+ . Fill this in the following space: +EGMR=1,7,”ENTER-NEW-IMEI-HERE” To find a new IMEI address, open the BB IMEI Generator app then copy the shown IMEI address. E.g. AT +EGMR=1,7,”990000862471854” then tap ‘Send AT Command’. A pop-up will inform you when the AT command has been successfully sent.
N/B: Remember to leave a single space between AT and the plus sign, otherwise it won’t work. If you have a dual SIM device, use AT +EGMR=1,10,”ENTER-NEW-IMEI-HERE” for under Radio information on Phone 2.
Step 6. Restart your device
After manually inputting the IMEI code, restart your device. This will get the job done – you shouldn’t get invalid IMEI notification.
