If you are a newbie completely, lets get familiar with Aftersales IMEI tool. If you look at the Aftersales too, you will see options ranging from Device Settings, Brand, Configuration, and Model.

Device Settings: This is where we have our Models Configuration through which we can add more models be it Infinix, Villaon, Tecno, Itel e.t.c
Configuration: This is where we can generate our IMEI TAC. You can genrate it online by using this link https://repl.it/@joelrf/Generate-IMEIs-based-on-TAC-code
Brand: which talks about brand of the phone i.e Tecno, Infinix e.t.c
Model: This is the model of the phone e.g x606, x608, la7, ca7 e.tc,
IMEI TAC: This is the 8 numbers that starts off our 15 digits IMEI, PSN, DevID, IMEI1, IMEI2, IMEI3, IMEI4, the initialize DB Button and the Space area.

How do we add More Models:

From the above Model Configuration, go to the empty column to add, by right clicking and picking Add Model.
Immediately after picking, it pops the next number, in which you can add Brands which could be Tecno, Itel, Infinix e.t.c
Select the Model you want to work on or have the DB files. Select the coresponding Model, Platform, Smart Phone, SIM SlotS, AP DB and BP DB files as illustrated before with TECNO F2LTE which is an MTK secure boot phone,using 2 SIMS and its AP and BP files.

How to fix MTK secure boot IMEI:

Select your right Model that you want to fix its IMEI. In this tutorial we are writing the IMEI for Infinix X606B
Click on Initialize DB
When it has successfully initialized the DB, you have the options/space to enter the 15 digits IMEI number.

Then input your IMEI numbers in the provided space, the first IMEI rectangular box and the second one too.
However, it has a rule. Since you know from above that IMEI TAC is the first 8 digits of the IMEI you want to write, then it must start it, you can complement it with the last 7 digits of the IMEI on the phone or generate based on IMEI TAC on this link.
If you are having two IMEI TACS as illustrated in the above, you must have the TAC start the IMEIs respectively as illustrated below.
After this, click on START and plug the phone.
