I have an att s iii and I want to use it on tmobile with a custom rom. Can I just grab a Rom from here, or do I have to push some sort of tmobile raidio (I'm not even sure if I have the terminology correct)?
I think you have to enable aws in order to use anything other than 2g on T-mobile.

Im looking to flash a custom rom to a Sprint HTC Touch Pro 2 for the sole intention of getting rid of my work phone (AT&T Blackberry). What is the best ROM (and easiest to switch between radios) to do something like this?
Thanks for any tips!

So far as I know you cannot flash a GSM ROM to a CDMA phone. It will not work.

The CDMA touch pro 2 is also a "world phone" so it has a built in GSM radio. The key is unlocking it for domestic GSM carriers. There are some unlockers to do this, but I am assuming there are various different radios and ROMs you can use that may make this work better or be easier to use.

I am aware of the "world phone" capabilities, and I stand by my statement. You will brick your CDMA phone if you flash a GSM ROM. You need to flash a CDMA ROM.
I believe that it is possible to "un-brick" back to CDMA, although so far as I know no one has "un-bricked" a GSM phone that was accidentally flashed with CDMA.
for better results... aka answers.
i suggest asking this question here --> linky.
because primarily your phone is CDMA,
therefore a CDMA ROM would be needed/required.
i also suggest a read of this --> linky.
it is very informative.
and should help a lot with answering your questions.
hope that helps.

As a CDMA/GSM phone we have the capability to use a GSM sim card, but we can only use tools that were specifically built for CDMA, including ROMs/radios. Flashing a GSM rom/radio will seriously hurt your phone, possibly rendering it unusable.
To unlock for a GSM carrier in the continental US, you will first need to SIM unlock, either through calling your carrier and requesting a SIM unlock or using the olinex SIM unlocker found in the CDMA forums: http://forum.xda-developers.com/forumdisplay.php?f=517
There are a couple guides to getting the tp2 working on various carriers.
Wellllll... Where are the guides
Please some help,
I have read and reand and dont find the answer.
i have a world phone, i just to know if there are custom ROMs for them, i use it mainly on GSM but i would not like to lose the CDMA option.
My device is a sprint TP2, i am using it in Mexico, with telcel GSM. I Just want a custom ROM for it, please Help!

Hi mate, even i have Sprit TP2.. with radio unlocked,even i use GSM network. u can switch to any ROM u want.. i m using ENERGY roms, n its working pretty well..
<< http://forum.ppcgeeks.com/showthread.php?t=86489 >> i m using this.
but only upgrade the phone with CDMA roms, as GSM Rom wont work on it. n u wont loose ur CDMA option.
I apologize if this is a stupid question, but I couldn't figure out the answer clearly after doing a search. I currently have the S3 with Sprint and am using a custom ROM. I want to switch to T-mobile (b/c their service is better in my area) and I know that I will have to get a new S3 that works on their GSM network. My question is will the same ROMs that worked on my Sprint S3 work on my Tmobile S3, or are roms carrier specific? Thanks
For the most part, roms are carrier specific. There's a sticky thread in development that you can make any rom work for your phone, you will have to get your hands dirty tho. Not just a zip and flash type thing.
Hey folks. I'm really tempted to get the T-Mobile S4, have it unlocked so I can take it to AT&T but I know at some point I'll be doing custom roms and probably radio upgrades since they come out once in a while. But will doing any of that break the SIM unlock? The one I fear most is probably radio upgrades but I've never moved a phone to another carrier so don't know all of the implications. Roms I doubt will be an issue but anyone know or have previous experience? At worse I have to keep calling T-Mobile to get it unlocked again if radio upgrades mess it up but I'd rather not be calling them all the time and if it is a problem then maybe I need to rethink this a bit more.
No, when you unlock it, it will be permanently unlocked, even you restore to stock rom, flash any other rom, radios, recovery or anything to OS or software related.
Before you flash a rom, make sure to try it in another provider with the factory/stock version, so you can make sure that the phone is working fine since the beginning,
T-Mobile S4 (SGH-M919) has a lot to offer in connectivity such as LTE Bands 1/2/4/5/7/17; in HSPA+/UMTS: 850/AWS/1900/2100MHz and finally GSM: 850/900/1800/1900MHz, so it surely will work on the AT&T network.
While the AT&T S4 (SGH-I337) only has LTE: Bands 1/4/7/17; HSPA+/UMTS: 850/1900/2100MHz; GSM: 850/900/1800/1900MHz.
For unlocking your T-Mobile S4, here is the link to the new T-Mobile Unlocking Policies: http://support.t-mobile.com/docs/DOC-1588. I bought my new S4 recently and they declined to unlock it before the first 40 days (postpaid) and before the first 60 days (prepaid) and there are certain other requirements to comply.
Lucky for me I found a trick on this forum to unlock it without the subsidy code (since my requests were rejected), it worked flawlessly and even I restore or flash any stock or custom rom, the unlocked state stays permanently because it's based on the NV system, just don't mess up with the NV base system.
If you want a phone with full LTE bands coverage, go for the M919 and it's bootloader unlocked from factory unlike the AT&T version which is bootloader locked. So, you can't go wrong with this model.
In terms of performance, the international version I9500 (without LTE support) is faster than any other S4 with SnapDragon 600 processor, I tested it myself since I have both I9500 and M919, the I9500 is octa-core (4-core of 1.6, and 4-core of 1.2) but only 4-cores work at the same time, in order to have a better power management, but even works in 1.6, it's a little bit faster than the 1.9 from SD600, i noticed on the graphics performance too.
And custom roms and other mods will come thru time for this specific model, just be patience, I have my M919 working with a non-US carrier sim card and installed custom rom Wicked v2 and it's working fast and stable.
I hope this info help you to decide!
Cheers!

hi guy,
i tried to find out how to make my m919v work on virgin LTE network. See many different answer but no one actually get it work. will that be possible to use lte on m919v? should i flash a tmobile stock rom on it or just tmobile radio? please link me for the download
thank you
I own the HTC One M8 16Go gold Asian version, phone is rooted with ElementalX kernel but stock rom. My phone works with 700 (b28)/900 (b8)/1800 (b3)/2100 (b1)/26000 (b7). I had the TW Mobile carrier in Taiwan. I want to add frequency bands to enable 4G LTE in Canada. Most carriers work with 1700/2100 (b4).
So how to add these frequency bands?
You need s-off ($25 by sunshine app) to change radio baseband (which changes band support).
You can flash AT&T or T-Mob US firmware to change to the corresponding baseband (both support Band 4 LTE). Or the correct Canadian carrier version's firmware; if you want to, and can find it (ATT and T-Mob are probably easier to find).
But you should also verify what bands your carrier uses for 3G, and that the new baseband supports it.
In my experience, AT&T has past or current associations with some of the Canadian carriers (still has partial ownership in some); and the networks share a lot of similarities. So AT&T firmware may be the best bet.
I installed Sunshine app but can't perform any test because it says Xposed Framework has been detected. I delete it but still the same error.

Try to restore the stock ROM, then root and run sunshine.
One thing to keep in mind, its not guaranteed that you will have LTE even with the proper baseband radio firmware. I've seen a number of folks that were not able to get LTE, even after s-off and flashing the proper radio firmware (that supports their carrier's LTE band). Don't know the reason for this, and never saw a solution. But just want you to be aware, in the event you spend the $25 on sunshine, and still can't get LTE.
But the fact that the Canadian networks seem to be very similar to AT&T, leads me to think the AT&T baseband radio will work for you. Not based on any specific/exact experience, just a hunch. So don't come and yell at me, if it doesn't work!
