Does this mean they work on Verizon ATT T-mobile all the same? I won't brick my phone by flashing a ROM no matter what, unlike some AOKP projects where you have to flash the right carrier's ROM?

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.

Hope this helps...
Is it possible?
Are there any international based Roms?
Always been my experience they run better on AT&T phones, idk about Verizon...
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:

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).
With the S5 devices with the eMMC 15 chip to aquire an unlocked bootloader, which ROM's from other variants would they be able to use without issues. Just trying to get a thread going for users and Dev's to share their opinions for others to gain knowledge from. Along with Pro's and Con's and 'how to's'. Happy ROM'n
T-Mobile variant seems to be the most supported ROM-wise. It's not locked down to 5.0 TW ROM's like the G900V (Verizon Variant).
The Verizon variant is the most locked down.
That is the question and for any helpful users to post.. Which T-Mobile, Sprint, AT&T(if any) and other variant ROM's can we "safely" install on our device. And what are the Pro's and Con's and the fixes(if any).... i guess this is more like a R&D thread to where everyone can post anything that may be helpful to people having questions of which ROM is suitable since we're now new to the unlocked bootloader and hoping more(the eMMC 11's) will be able to be unlocked as well. I'm pretty new as far as setting up a "guide" type thread. But as info is passed out, I'll try to update the thread for information of the ROM's and Pro's and Con's about them.

Well now that we have an unlockable bootloader... Well, that has to go to AT&T now
To my knowledge, most variants use a generic G900F rom, because those carriers strictly use GSM bands. Verizon and AT&T use CDMA bands, which aren't fully supported in these roms. @jrkruse has released patches (thanks ) that will help with compatibility, but I think these are confined to 5.X at the moment.
I **think** there may be some modifications made to Verizon & AT&T roms regarding firmware, but I can't be sure. It seemed there was more than just CDMA support in the zips provided by JrKruse.
When flashing a G900F rom (should be safe) without patching, you'll probably only have glitchy and cutting out 4G/LTE, with no calling or SMS. Some modifications of the APN settings can maybe help a little, not much. The use of third-party texting apps has been shown to provide some support, but not complete.
Of course, all of this is just based on my strange reasoning, I could be completely wrong on some parts.
Besides cell services, these roms will work fine. Quite fast, too.
As I have stated in the other thread, if a rom is 6.0 and not touchwiz as long as it has a dev build it will boot and work without much more than verifying the apns. 6.0 Touchwiz is simply a no go, just dont try it. It is not worth the headache to get it to work.
I know cm, aokp, aicp, and Resurrection remix all have dev builds there is a couple of others that I think but havent really looked.
@camcorder123 ATT doesnt use cdma technology, they were just dicks and locked the bootloader like Verizon.
@limeaide Oops, you're right about ATT. Sure, a dev build will be easy to run, the problem is that nobody makes them. We've got a few ported but no official developers (from what I know) are actively developing for the phone. That'll probably start up sometime soon but until then we need to find a way to make the generic roms work.
Upon further research, I think it's gonna be a *tad* harder to get G900F roms to work than I thought. The reason only LTE works is because the LTE standard requires a sim card, so there's no problem in getting the phone to read the card and connect to the tower. But, CDMA is separate from the LTE standard - each phone is whitelisted on Verizon's servers (I'm assuming with the IMEI number) and does not need a sim card to access voice and SMS. This is unlike GSM, where everything is through the sim.
So I dunno, we might be stuck for a while. I wouldn't flash roms made for variants other than the KLTE edition, it might be the same outcome even though they may support CDMA.
Looking to pick up a GS5 and put on Nougat via LineageOS. Is there a certain carrier's phone that is more desirable than others? Since I do not already have the phone I would like to acquire the best one to get to my ultimate goal of unlocking and putting on Android 7. Phone will eventually be used on the AT&T network.
Thanks in advance,
Bob
Try and see if the international G900F works on AT&T, or simply get the G900T, to not go through the hassle which involves an international version.
If you like using custom roms and such STAY AWAY FROM AT&T!!! Bc they lock there bootloader's haha
AT&T Galaxy S5 has Locked Bootloader, which means you can't flash custom ROMs. Sprint variant has different hardware for CDMA support, so some ROM may be incompatible. If you can invest on G900F (International Version), G900F is the most ideal one for custom ROMs (Or G900W8, which is Canadian version) Otherwise, you would want to get G900T since it has unlocked bootloader.
