How To Access Engineer Mode

There are few ways to access engineer mode and I am going to share these two simple ways.


First is to dial these.
*#*#3646633#*#*

3646633 is equivalent to ENGMODE so better keep that in mind.

If the first one failed, try this!

You need a root access and Mobileucle Tools. You can download it on Google Playstore for free.

If you have installed Mobileuncle Tools already, open it.
It will ask for root access and just grant it.

Click Engineer Mode

Click Engineer Mode (MTK)


Voila! You have now accessed the Engineer Mode!
