Will this custom ROM unlock the phone?

I have bought this phone from T-Mobile, but chose the wrong option when buying (not the unlocked one) and now the only way I could find to unlock the phone would be paying for the network unlock code (around $30).

Would anyone know if by flashing this ROM it will unlock the phone to use another carrier's SIM card?

Any other option on how to unlock the phone using another method would also be greatly appreciated.

No, the custom ROM will not unlock the phone

Already found the answer to my own question. I flashed the custom ROM to the locked phone and tried to place a SIM card in it, but still get the Invalid SIM card message and it requests the network unlock code.

I can also say that kitkat metropcs twrp backup works on the Univision variant and it works with a sim card from another country, thanks!!

EDIT: This ROM won't unlock your phone, this is another part of the device that is not dependant on the rom, to unlock you'll need an unlocking box like z3x, or pay for an imei unlock code, mine could be unlocked with 13 dlls from unlockscout, samsungs made in china.

What is the version 4.4 or 4.2?

Phone is now unlocked and updated to Kit Kat

Indeed, the part of the phone responsible for the network lock is not messed with by the custom ROM or the update to Kit Kat method, but I actually found a way to unlock without a z3x box or having to buy the unlock code online.
The phone I was trying to unlock is a friend's phone, but I have my own phone and it was bought already unlocked, and is the same model. The trick here was to find out that the network code lock was part of the EFS partition. I made a full backup of my phone (unlocked) through TWRP and restored it in my friend's phone. It did unlock. Then it was just a matter of resetting to factory defaults and performing the procedure to update to Kit Kat and it now is unlocked and updated. \o/

Heres my question, if the phone is from tmobile how did you get kitkat? Unless you did it with the METRO backup

cm version

Thanks. Looking forward for that CM ROM.

One potentially noob question: cm11 is based on 4.4 while this device is officially still 4.2.2. Would that be OK?

 

[tazmaniondvl]

Yes thats why people started making xustom roms

I read somewhere that someone was trying to download KK update from T-Mobile this could be just a 4.2 update or they could be pushing it. Maybe new lights are shipping with KK as well who knows

There are many phones who are stuck on outdated firmware. Gnex, nexus s, htc mytouch 4g/slide all running kit Kat. Many many more examples. The Roms may not be stable due to various reasons (no source, outdated hardware, lack of Dev etc) it is possible

Is there a test that will show if a phone is locked or not. I hosed my efs partition a while back and had to format it, change permissions, and reset to factory default to get my Galaxy Light to boot. Does that mean that my phone is unlocked?

Yes, I did it with the MetroPCS backup. Tried to flash the kernel of KitKat straight from the T-Mobile system on 4.2.2 but it did not work.

The work I'm doing is based on the metro PCs released kernel source and device files which are 4.4. They have the same everything just different bloat from carrier.

I believe you are looking for an app that is able to test if the phone is network locked or not. I do not know of such an app. The basic test you can do is try to insert a SIM card from another operator and see if it allows it or displays the message of it being an invalid SIM, asking for the network unlock code. And you don't need to buy another SIM, just borrow a friend's, it will only take a minute...

 

[GJSmith3rd]

Thanks, that's my little problem in that I don't have access to a micro or mini SIM like the one in this device.

 

[tazmaniondvl]

Anyone know where the boot animation is? Or how to change it?

Greetings XDA Zombies!
Got the T399NUVUANH1 working on my T-Mobile T399. Having issues getting ViPER4Android FX drivers to work. Have BusyBox Pro and seems that it wont install property. The ViPER4 2.3 version says the drivers are installed but actually not working, and the ViPER4 4.x version I keep getting the drivers failed.

Appreciate any help.

Footnote: X Tether works!
Bummer. Think TMO watching XDA and clamping down on whatever loose ends they can bind.

Metropcs GL

Will this work on a galaxy light with Android 4.4.3? Does the build have to be the same?
