fix for adding IMEI to new mtk64bit SoC topic

hey guys n gals,
recently a friend of mine had to restore his IMEI numbers back onto his Ecoo Aurora mtk6752 64bit device,as you may or may not know mtk droid tools and mobile uncle toolbox will not allow you access to do this with the new 64bit chipset so lucky for us my friend @percymama over at china-devices.com came up with a solution

original thread in link below

i will apologize if this solution has already been posted here on XDA

no responsibility will be accepted by anyone if you brick,break,dissolve,eat or throw your device against a brick wall whilst attempting this fix

So there a few tutorial on how to fix/reinsert your IMEI numbers if you have flashed a new Rom, or performed a Factory Reset, sometimes this will clear the IMEI numbers, meaning you get no signal anymore.

The IMEI number needs to be placed back into the phone, the easy way is to use MTK Droid Tools, but as I have discovered this wil not work for 64bit new generation systems! and using Mobile Uncle to restore the IMEI from a BAK file also will not work, essentially these Two programs are waiting for updates.

There is however a solution, there is an app called "MTK Engineer" on the store

In this app you can amend the IMEI number

(1) Open the app and click the MTK Settings
(2) Go to Connectivity
(3) Go to CDS Information
(4) Go to Radio Information

Once there you will see Two options

(1) Phone 1
(2) Phone 2

So choose Phone 1 to begin

Once in this section, you will see at the very top AT+

Tap this and it will open the keyboard - type any letter, and then go back, as this will show an auto selection for you to choose.

Choose AT+EGMR=1,7,"" (insert IMEI here)

This is where you will type in your IMEI Number

Once its typed in hit "Send At Command" and reboot your phone and type *#06# and see what it says
(if its still invalid see below)

Now there may be an issue, so if you get a userbuild error when you type in the IMEI number and hit "Send At Command" there is a quick fix

In other words if you use the above method but it says "Blah Blah User build error" then what you need to do is alter the AT+ section

Where you begin AT+ make sure you make a space between AT and + so instead of AT+ it will be AT (space) +

Then proceed as before to insert you IMEI at the end of the line

Sometimes even though you will see the message "Command Sent" - when you reboot and type *#06# it may still show IMEI is invalid.

So go back to the app and do everything as before except this time at the end of the text where there are 2 Quotation marks you need to type the IMEI in between these!

So instead off having AT +EGMR=1,7,"" and then typing in your IMEI

You need to have AT +EMGR=1,7,"123456789123456" (Obviously your IMEI number here not 123-----)

Just double check that there is a space between AT and + and that the IMEI number is between the Quotation marks as above and then hit "Send At Command"

Reboot your phone and type *#06# and you should have a working IMEI again

Any question just ask

all props go to @percymama for this guide....good luck
