Ok. so after being with AT&T since 1998, I went to T-mobile and activated an account today. Last night I also did the mod enabling all the T-mobile AWS, HSPA & LTE bands on my AT&T Galaxy S4 and it was a success. Everything works great, I already have the T-Mobile Sim card installed, and T-Mobile LTE and HSPA is very fast.
I've been flashing ROMS, Kernels and radios for several years on many many different phones and tablets, However this is the first phone I've delt with, with a locked bootloader and also the first time wanting to use a different carriers ROM. The phone is already rooted, with TWRP recovery and I'm running CM 10.2.
Should I flash a T-mobile radio and ROM now that I plan on sticking with T-mobile. If I do, can I flash any T-Mobile based rom, and TWRP will automatically Loki Doki it or whatever it does lol? I don't usually have these questions, but this locked bootloader crap really sucks. The phone is only a month old, so I don't really want to buy a T-Mobile version when I got all of T-Mobile's bands working.

You need to flash the rom, then your loki doki kernel, I do not recommend flashing a different radio, that could brick the device, although, it has been done, and I think our MDL and MF3 modems are sufficient enough to get the correct speeds for your device.

Thanks for the reply, my last question is, how do I Loki Doki the Kernel. The MDOB ROM i was using, and also CM10 did the self locking thing, Is LOKI something I flash after flashing the ROM.

Go to my guide here, at the bottom of post #1 is a patch called loki-doki.zip, that would be what you flash after every rom, I do that everytime I flash roms.

I have an ATT S4 I337 and am trying to install T-mobile ROM because i am using a t-mobile sim and want to use wifi calling. Is it possible and how?
Here is what i have tried:
1. Installed safestrap 3.72 and rooted my i337
2. Installed a Tmobile NB4 rom (Fenny Rom) through safestrap and/or loki doki kernel
3. Installed deadly venom magic tool files through ODIN
Upon reboot, the animation screen shows up with T-Mobile 4G LTE logo but phone stays stuck on this screen.
I also tried Insane ROM and this time i get the animation screen with smoke going over but never moves forward.
Is it at all possible to utilize a t-mobile ROM on this phone or not....help would be apreciated.
Sorry mate
I'm not sure if you can- if you're on NB1, you can only install ROMs with the stock AT&T TouchWiz kernel, AKA Safestrap ROMs. I don't think T-Mobile ROMs use the AT&T kernel, lol. Maybe you could try hacking together a T-Mobile ROM with an AT&T stock kernel and see if that works. Sorry man, but I don't think it's going to happen. However, if you do hack a ROM together, I'll be more than happy to test it out, as I'm on an AT&T Galaxy S4, but I'm using it on the T-Mobile network. (SIM Unlocked using my own method without dialer codes or an AT&T SIM).
Best of luck! :good::good::good:

I was looking for exactly something like that and found out joseph230 has come out with step by step guide. Works like a charm!!!

I downloaded hyperdrive rom and installed it 3 times and it would break data and wifi.
I used att modules.
then I tried the tmobile modules on install and it works great.
so my question is should I use tmobile roms or att
I just wanted to know before I go download crazy because of excitement I just came from a locked down Verizon s4 and now my i337m has unlocked boot loader and cmw on it yay
Just ordered my wife a G2, it is unlocked however it is the AT&T variant and we are on Tmo. I have read that someone took a Tmo rom and made it possible to flash this to the AT&T model along with the KK baseband so that we can use Tmos wifi calling. However I would like to know if I can simply just flash a Tmo stock image and flash the KK baseband if this will work or am I looking into this all wrong?
This is where I read about the Tmo on AT&T rom:
http://phoneprouser.com/lg-g2-rom-that-supports-wifi-calling-on-att/1007/
Can anyone tell me if the ROM mentioned in the link above is this the latest ROM for the G2? Thank you in advance.
Side Question, if I want to flash Cyanogenmod and still want to retain the wifi calling can I flash the Tmo rom along with the aforementioned KK baseband?

THIS IS AN ABSOLUTE AND COMPLETE NO GO, FLASHING A FACTORY IMAGE FOR A DIFFERENT MODEL CAN HARD BRICK YOUR DEVICE, IN FACT I'D PRETTY MUCH GUARANTEE IT!!! GO INTO THE ATT DEVELOPMENT THREAD AND FIND SAID T MOBILE ROM FOR YOUR DEVICE, FLASH THAT IF YOU WANT TO. As an answer to the side question there is no way to retain wifi calling on cyanogenmod, especially on a non tmo device. Finally as for the baseband find out what baseband the respective ROMs need (the tmobile one for ATT G2s or the CM build you choose to use).
Hello!
This might seems a little strange but I can't seem to find a straight forward answer. So everything I read, talks about the 900V being restricted due to it's boot loaded being locked and there are very few options with choosing ROM's. Is this common:
1) I have the 900V and i have safestrap 3.75 and Alliance Rom 2 with NE9 kernel, currently not in the states and i'm able to use a different sim card. It is using a 3G carrier vs Version LTE, my phone still says sim locked to Verzion but i'm connected to the current SIM card and pulling data off of it. I did not think this was possible with Verzions choke hold on everything.
2) Am i truly limited on what ROM's i can load on my phone? I feel like having safe strap i should be able to install more ROMs than the few options listed on here.
3) I enjoy the Alliance ROM a lot, any recommendations on what ROMs i should experiment and might enjoy. And can i install them with safestrap?
Thank you all for your time!
All Verizon phones are unlocked but the bootloader is locked. This means only stock ROMs will work, and they've locked out most other carrier's LTE bands.
stick to Verizon development thread and try all of them there.
Got a used S4 with "custom unlocked" boot screen. Is it limited to SafeStrap?
As mentioned in the title, I just got a used S4. It has AT&T software loaded on it (NC1). I can load SafeStrap *but* my provider is T-Mobile.
The first screen shown when I turn on the phone has an unlocked padlock icon with the text "custom". Does that mean I can use a recovery other than SafeStrap? I ask because I want to run T-Mobile ROMs (or Cyanogenmod preferably) which aren't always TWRP compatible.
If I am stuck, are the AT&T ROMs going to work well with T-Mobile?
As long as you have AT&T S4, you'll be limited to using Safestrap recovery only. The problem is AT&T's choice of locking the bootloader that prevents you from flashing any other recovery or any non-Samsung ROM. You can't flash a T-Mobile ROM for this reason, either.
Someone successfully got WiFi calling working on AT&T phone, though. If you're interested, check it out.
Almost all AT&T Samsung ROMs work perfectly with T-Mobile service. You can even flash some i9505 ROMs, too. Again, Samsung ROMs only
Is the "unlocked custom" boot screen normal for these phones?
This seems like a pretty interesting phone! Haha, so if I understand you correctly, the phone is the T-Mobile variant of the Galaxy S4 with an AT&T Rom loaded onto it with the Safe Strap Recovery? OR is it the AT&T variant of the S4, with a fancy padlock boot screen and you're a T-Mobile customer?
As @xymic posted, there is a way to get a T-Mobile rom on the phone!
I have two AT&T S4's and both are being used on the T-Mobile network. One is running a Lollipop AT&T rom and it works great with my T-Mobile sim! No problems. Another is running the Kitkat T-Mobile rom and it's working flawlessly as well!
I'm not too sure about the unlocked custom boot screen however. It appeared once for me but it didn't come back after I started flashing different roms.
I don't know what carrier the phone used to have. I assume AT&T because it has an AT&T ROM loaded. If that "unlocked custom" icon is something you've seen then this is probably a very normal carrier phone.

That custom unlocked thing is normal for anyone on here at least. Means there's either root or modified system files, or there were either of those and the status hasn't reset yet.

False. If you're on the AMDL bootloader or older, you can use Loki. The chances of finding a used Loki'd phone are slim and you're are better off with the international version with the correct bands, if buying a used S4. MUCH better access to ROMs.
