I recently acquired a Motorola Droid Bionic from a relative. Their contract ran up and they've upgraded to a Galaxy S4. They are on Verizon and I am on AT&T. I have searched for a way to unlock the SIM so that I can use the phone with an AT&T SIM card. Could someone explain to me how to do this and what I would be losing and gaining by doing this. I am running 4.1.2 and have read that unlocking on Jelly Bean won't work correctly. Please help. Thank you.

That thread contains all of the best information including a link to an updated guide for doing the necessary modifications.
You can get H+ on ATT using the Bionic but not LTE and the radio performance can be sub optimal depending on where you are located.
I suggest you read the last few pages and decide if you want to do the work required which involves several procedures including rooting and editing the NVM with RadioComm.
It all works but none of it can be characterized as simple. Good luck!

Originally, I posted this on the beginner's thread, but no one would help me
So I decided to make a new thread.
I have an unlocked HTC One 32GB purchased directly from HTC, and discovered that it could not use the wifi-calling function of t-mobile. So, I managed to unlock the bootloader and root, but don't know what to do now.
How can I just add the wifi calling option in the settings, and restore the apps I lost while unlocking the bootloader?
Also, can I get official updates from HTC, even though I'm rooted?
Please, make the answers user-friendly (I'm very new to this community and android- first android phone!)
Any help is very much appreciated.

You need a ROM that supports wifi calling. After you unlocked your bootloader, you need to either flash the stock T-Mobile ROM or a custom ROM that has wifi calling built in. Keep in the mind that a lot of the newer ROMs using 4.2 base do not support wifi calling yet so you need something with a 4.1.2 base. I'm using ARHD 9.4 and wifi calling works flawlessly. Hope this helps.
As the subject stated, I have AT&T version of the Galaxy S4 Active. The phone is unlocked (code provided by AT&T) and now I have a T-Mobile SIM card.
I want to do Wi-Fi calling, but couldn't find any information in this forum or when Googling it.
Can anyone provide step-by-step information on this? Preferably, I don't want to install a custom ROM - I use stock ROM (rooted) and it has been stable so far.

Check this thread for T-Mobile WiFi calling ( http://forum.xda-developers.com/showthread.php?t=2302313). You've got two things working against you though. First you have the AT&T version of the phone, so ours locked down and you can't fully flash ROMs to the phone. You can use SafeStrap to flash ROMs but because of the bootloader being locked your stock with the stock kernel. Second, nobody has got T-Mobile WiFi calling working on non T-Mobile ROMs. So basically you can't do it with the phone you've got.
Thanks for the detailed information. Looks like it's not doable given the locked boot loader. :sly:
My current biggest problem with mod'n the i537 is primarily with my objective to convert it to a TMobile master piece.
Speak up IF anyone has done this successfully please. It is challenging because....
1) I have yet to find a version of SafeStrap or other similar program to assist in the ROM install that states it is compatible on i537 running 4.2.2
2) I have not found a thread confirming that there is a stable TMobile ROM tested on the i537 active
please chime in if you have any experience with these objectives. I would like to get this phone working at it's full potential ASAP.

what @Devo7v said, that method works for 4.2.2 and if you do upgrade to 4.3 you can follow this http://forum.xda-developers.com/showthread.php?t=2721726. I personally still am on Tmo and using the 4.2.2 method cause I don't wanna redo everything unless I update to 4.4.2 which as of now doesn't exactly have anything to change the QCN. ;[

I am convinced there is NO WAY to get ALL TMobile services to work on the i537 active. There is a rumor that it may be possible on the international i9295 Active BUT it does not have the LTE 4g receiver frequency!!!
No one seems to have successfully restored wifi calling and tethering on a TMobi ROM on the i537 active so I am selling mine back to an ATT customer and picking up a TMobi s5 or standard s4.
Hello I have a verizon note 4 and am using it on tmobile my question is this, Now that the 910v can be rooted what happens if I root it and download a tmobile rom and install it on the phone? Will it work or will it brick the phone? I have no idea if there is any real difference between the verizon note and the tmobile note besides the carrier. Any input would be appreciated as I cant stand the verizon bloatware and would love to have my tmobile stuff back
thanks in advance
As far I know not possible
Tmobile is GSM model and verizon is CDMA frequency bands different.
I did something similar with AT&T G2 and loaded a Tmobile ROM on it. First you need root and TWRP or equivalent. and then some developer have to created a modified bootstack that are tailored for your phone model to work with the rom. Once you load the bootstack, then you load the rom without the radio. Not for the faint of heart.
Hi all,
Im new to this website but not new to installing customs ROM's on phones. Its been a while but i did it years ago on my S3. Also, I know there are probably threads out there already for this so if this is just a redundant question please forward me to the right place b/c i haven't been able to find a clear answer on my own.
So here is my situation. I have a SM-G900A that I requested and unlock code from AT&T for and is now "unlocked" and I am running android 6.0.1. My girlfriend has a SM-G900V that is supposedly been unlocked by verizon and i moved over to my AT&T account and its working fine (with the exception of lack of LTE data). To my understanding it is not possible to flash a custom ROM on either of these if they are on anything post android 5.0 release. Is this true? I have not been able to find any custom ROM build that say they are made for these models and TWRP doesnt have a version specific to these either.
Has anyone successfully put customer ROM's/bootloaders on either of these 2 devices? I have really only used Cyanogenmod in the past and was very happy with it. But all i have seen is that people say that these 2 models are SOL if they have android v.6 on them.
Any help would be appreciated. Thank you!
Check the link below, the first 4 posts or so have the information on downgrading and rooting. I don't know about the Verizon version, the AT&T version bootloader is completely locked down so we can not flash a custom recovery like twrp. Flashfire works like a charm though. The custom roms are limited and pretty much lollipop variants. There is currently no root or custom Rom for marshmallow.

flashfire gives the error "Please update SuperSU to v.2.40 or newer" which I already have. I tried the older ones 1st and it gives the same error. I am not sure what to think about it except I got it to work before with the exact same files from what I recall. is there another proceedure perhaps?
