 How to unlock Samsung Galaxy Avant (SM-G386T) T-Mobile

The Samsung Galaxy Avant (SM-G386T) cell phone from T-Mobile USA is using a custom firmware preventing the phone from being unlocked by code as there is no way to enter it (the phone is simply not asking for “SIM Network Unlock PIN”).

So what do you do if you get an Unlock Code but you cannot use it?

Now there is a solution consisting of an upgrade to the firmware of the phone with MetroPCS Firmware instead of T-Mobile, and this will allow the phone to ask for the Unlock Code. Below you will find a tutorial about how to do this. Once you flash (update) your Phone with this New Firmware, please make sure that your Samsung SM-G386T is asking for “SIM Network Unlock PIN”. And if the answer is yes you can then click this link to order the Unlock Code of your Samsung Galaxy Avant from T-Mobile USA.

Step by Step Tutorial Firmware Upgrade
