Recently, I have my friend whose Android phone got a problem with the "pattern lock". She went all by herself fixing it. The phone returned back to the default settings, cleared everything that were stored on internal memory including her messages, contacts and even the IMEI.
What is IMEI, anyway? IMEI stands for International Mobile Station Equipment Identity which is really complicated when explained to persons who are not keen with deep technical terms.
To make it simple, IMEI main purpose is to connect the phone to your network and it serves as identifier as well. Stopping or corrupting the IMEI built may caused serious problem like unable to access your network or losing the signal.
How come the phone's IMEI was damaged? Android phones are prone to this issue. My friend's Myphone Agua Rio Craze had a "pattern lock". As long as she have that problem, she can't use her phone.
What she did was to "hard reset" her device. This fixed the "pattern lock" issue without knowing that she also deleted the phone's IMEI.
Dialing *#06# will give you the IMEI. When I checked her phone both IMEI for SIM1 and SIM2 shows "Invalid IMEI". So, I need to restore the IMEI to have this resolved.
- First, dial *#*#84666364#*#*.
- Go to CONNECTIVITY, RADIO INFORMATION then CDS INFORMATION
- Phone 1 is IMEI 1 or SIM 1
- Phone 2 is IMEI 2 or SIM 2
- Tap PHONE 1 then type
Note: You should place the IMEI inside quotation marks ("xxxxxxxxxxxxxxx")
Tap PHONE 2 then type
- Reboot the phone.
- Check IMEI by dialing *#06#, IMEI should be restored and your phone is ready to use!

Additional Helpful Tips!
Userbuild does not allow you to send the command to rewrite the IMEI when you typed the command like this AT+EGMR=1,10,"123456789012345". As you can see there is space between AT and +EGMR. It should be AT +EGMR=1,10,"123456789012345". Again, watch carefully for the space so that the Engineering mode will allow you to run the command of rewriting the IMEI.
Please check my video here for better reference:
Set by the default, the command box has "AT+" already. Try to type any character and delete it using the backspace. Engineering commands like AT+EGMR=1,7,"" and AT+EGMR=1,10,"" should be available on the dropdown. You don't need to type them manually, just the IMEI inside the quotation marks and all is up!
