How to Unlock APN Options for Factory Unlocked SM-G900V? [Unable to Root?]

[LukeCodes]

Hey everyone, thanks for your help.

So I recently bought a SM-G900V that was originally used on a Verizon plan. It was factory unlocked and sent to me. I have been using it on the AT&T network through Cricket for about two years. Recently I decided to add a data plan to my phone, and I researched and found I have to add a custom APN profile for it to work with the AT&T network. I discovered that the original Verizon APN is locked, and I cannot add any other options or change the original.

I researched for a bit and found that I can change the settings and add a new APN after I root my phone. I have previously owned Nexus 4 and 5 phones, so I have had experience in this subject. However, I didn't realize what a task this would become. I have tried towelroot (with all possible modstrings), kingroot, and multiple other sources, but all say that my phone is not supported.

Do you have any suggestions? This is very frustrating as my Nexus phones were VERY easy to root in comparison.

Thanks, Luke

You need to backup all important data to your pc and know your Samsung sign in info

To root phone it has to be on bok3 firmware or pb1 firmwares you can download these firmwares on sammobile.com once they are downloaded

Download Odin to your pc and got to samsungs website
And download the driver for your device

Then get a usb cable for your phone and connect your phone to your pc

Open Odin on your pc and place the firmware file in the ap/ pda slot

Boot your phone into download Odin mode

Then click start
Your phone will bootloop

Boot to recovery mode and wipe data and cache

Then phone will boot

Now find ok3 root method on xda under s5 Verizon section

Okay thanks, I'll try that tomorrow. :good:
As a side note, if I try this method, will I be able to bring my GS5 to Verizon later and use it on their network with a different SIM?
Thanks, Luke

As long as you don't return the phone for service or warranty you will be fine if ou need to return it or get it repaired just flash an official firmware first

It passed Odin and I'm setting it up now.
I'll update you after I attempt to root.

Okay! It's finished! Now I just need to work on changing the APN profile. Thanks for all your help!

As another side note, can I update to Marshmallow and keep root?

Thanks, Luke
