Update 19th June 2015: Too complicated ?! Don’t want to risk to flash your phone with new firmware ?! Please take a look to our new Official mobile “Device Unlock” app method to unlock your Samsung using official Android App.

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”). Before this post, the only way to Unlock the phone was by using the official T-Mobile  “Mobile Device Unlock App” which is an Android app called “Device Unlock” that allows you to request and apply a mobile device unlock directly from the device.

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.
