How to Fix Invalid IMEI Error on Android

Invalid IMEI error may occur after a ROM installation or after upgrading the android. This error causes a network problem which doesn’t let you make and receive calls on your handset.

Recently, I got this invalid IMEI error after installing ROM in my Micromax mobile. There are two simple ways to fix this IMEI error. In this post, we will see both methods in detail. Let’s get started.

Fix Invalid IMEI Error

Method 1

This method has two requirements.

Requirements:

  • Rooted device

If you have the above two needs, then you are good to go.

Steps:

  • Install and open mobileuncle tools [This app isn’t currently available in the play store. But, it is still available in other stores.]
  • Click on IMEI Backup Restore (MTK) option.
  • You’ll see four options and the last two options are meant for the IMEI restoration task.

Restore IMEI from SDCARD(MTK) – If your IMEI backup is in the internal storage, you need to use this option.

Restore IMEI from SDCARD2(MTK) – If your backup is on the sd card, then you need to use this option.

Make sure you have the IMEI backup in the root directory of the storage. Now, use the option and restore the IMEI.

Method 2 [Rooted Device Only]

Steps:

  • For this process, you need to know the IMEI numbers of your handset. Dialing *#06# doesn’t show the IMEI numbers now. Instead, it will show the error like this:

  • So, I suggest you check out this article (take a look at “Remove Battery” and “Your Device is Lost or Stolen” section in that article) to find IMEI numbers and note it down.

Now:

  • Go into engineering mode. To do this, download and install Mobileuncle Tools app and open it.
  • Select engineer mode. Tap engineer mode (MTK).
  • Navigate to connectivity tab > CDS information > radio information > Phone 1
  • At the top, you’ll see the AT+.
  • Beside the AT+, type the following command.

EGMR=1,7,“IMEI NUMBER”

  • Within double quotes, type your IMEI number. Press “SEND AT COMMAND” button. You’ll see a message like this “AT command is mSent.”
  • Now, reboot the phone.

You’ll see the first sim is working. If you have the dual sim mobile, you need to use the same procedure for the second sim.

  • Go to phone 2. Beside the AT+, type the following command in the input field.

EGMR=1,10,“IMEI NUMBER”

  • Remember, you need to use the second IMEI number in the input field and press “SEND AT COMMAND” button.
  • After you were done, reboot the device.

That’s it. Both the network problem and the invalid IMEI error got fixed. Dial *#06# to check the imei number of your handset.

Additional Hint [optional]:

I’ve also faced another error after installing ROM. That is NVRAM WARNING: Err = 0x10 error. You can go to the wifi settings and confirm whether you have this error or not.

If you have this NVRAM error, then I suggest you visit this page which has the solution.
