I am confused on why there is an entirely different section for the TP2 CDMA versions. It's especially confusing considering that it is a global phone that can run on both CDMA and GSM. So what's the difference?
Does a CDMA version of the phone have a different OS somehow, which is why there aren't any CDMA roms out yet? Would it screw up my phone to install a GSM ROM to my TP2 (Verizon)?
Any help would be appreciated.
cdma and gsm are 2 different cell phone technologies. kind of like vhs and betamax. 2 different ways to provide cell phone service. normally your phone uses one or the other. sprint and vzw use cdma while att and tmobile use gsm. this is all related to the built in hardware not the os. the att version only has gsm built in and can only use gsm's network. to compete with with gsm providers bragging about world wide coverage vzw and sprint have world phone version that have both cdma and gsm radio's built in. they are locked to use the cdma radio in the usa but can roam on gsm networks while traveling abroad. they have similar os's but are different enough that you can not use the gsm version on a cdma phone unless it has been modified for it. the cooked roms you see in the cdma section i believe are gsm roms that have been modified and tweaked to work on the cdma phones. since the gsm version has been out longer the 6.5 os has already been release officially. sprint and vzw will eventually get a 6.5 os from htc which they will tweak and cripple to their liking and then they will each release their own version. also remember these roms contain both new os versions and radio software. the main danger of loading the wrong version is probably with the radio. the gsm version will not have the information to run with sprint or vzw's cdma radio hardware. if you want to load a new rom you need to use the tweaked ones here in the cdma section or until vzw releases a new rom.
It's coming together..
Alright, so I am beginning to understand about the differences, thank-you so much for your information. But I am wondering if there is someplace that I could go and read up and the specific differences and how to start helping tweak roms, write them, or such. I am interested in actually coding, or however the people here make their programs for cell phones. Any websites that you could refer me to or anyone here who is looking to take on a student?
http://lmgtfy.com/?q=difference+between+CDMA+and+GSM
Nice.
Alright, I get the picture. From now on I shall not ask questions to which I can find answers on Google.
That link was very cool by the way, I have no idea how you made it so I could then interact with that search query.
They're just two different types of technologies.
The main difference is what frequencies they operate on.
On the TP2 the difference is deeper then just the radio technology that you can Google.
Externally it means you have a headphone jack on the CDMA version.
Internally there is an FM radio on the GSM versions. And the CDMA version as noted has a GSM radio secondary to it. And some GSM versions have a front facing camera.
That helps a bit, but not all the way
Alright, so I can understand the differences in technology that comes with the two diffferent carriers. But why are the ROMs so different between CDMA and GSM? If there are only a couple of technology differences, shouldn't it be easy to change that and make them work? Or does have it to do more with the radio frequencies and coming out with a working ROM that makes them still be able to connect? If so, I thought the different Radio installers came in different packages and were installed after the ROM.
Thanks for all the info.

WTF? There are plenty of CDMA Roms, check out forum.PPCGeeks.com it's the main CDMA Windows Mobile forum. smh
I guess I was looking in the wrong place...
Alright, I will go check out over there. I was looking around here for a CDMA ROM, and I just didn't see any. Thanks for the point out.
my fault re-readin what I wrote I see that I'm coming off rude I really wasn't trying to be. Here's some Rom tips once you unlock for Sense 2.1 (with weather clock and fullscreen weather animations) go with MightyRom, it's by far the fastest most stable with great battery life that I've tried. For Sense 2.5 you can try JuicyRom or EnergyRom I found Juicy's to be very fast but 2.5 just doesn't compare to the stability and speed of 2.1. Good luck.
No worries
No problem, I thought it was just becuase I was a new user asking obvious questions. Thanks for the help.
OKAY so I decided to update this thread:
There are two versions of the One X. One with aws bands and one without. I have a device without AWS (I am about 80 % sure). There are reports of people getting 4g on AWS with the Rogers Version as of now, and more testers need to check it out as it could still be possible on ATT.
This flash here theoretically could enable the One X radio to lach onto AWS (The radios here are for the One S Ville.)
http://ville.giev.de/?page_id=42
I have flashed all three, and although I did not get 4g, I got faster ping and a near immediate connection onto T-mobile. To all the people saying this will "brick" the phone, it does not and you have nothing to worry. But as always make sure to do a backup. The radio hacks for the Skyrocket/Note were also based on flashing the Galaxy S2 radio directly on top. This should work the same.
I'm interested in this as well. What does is involved and the risk? I don't have warranty on my phone, so I'm a little bit leery in being first.

if your rooted ull should be fine just make a back up of ur current set up. this is just a clockwork flash, it may not even flash, but if it does then there's a high chance of 4g.
i've done radio hacks before for the droid 3/skyrocket/note all from a similar concept. ex. flashing the t-mobile galaxy s2 radio on the note, to enable 4g.
if anyone could provide me with a better solution for an unlock i am sure i can get this to work. seems that the htc unlocker server is down right now
it's the same thing as flashing different radios via clockwork posted in the One X android dev forum
I'll give it a try, hopefully it won't mess anything up. So I just flash the radio in recovery. If no good, I just flash the correct radio again?
There is a one click no HTC Dev bootloader unlock in the Dev forum.

I flashed:

0.16.31501S.17_2_10.23.31501S.10L
From your link. It flashed correctly. The phone on data and voice still works. I confirmed the version in Settings is not my original:
0.17.32.09.12_10.86.32.08L
I'm still on Edge, but I'm in a crappy cell area, so still not certain if radio or my area. I might give the:
Radio from Stock T-Mobile US (update by rhcp)
0.16.31501S.02_10.18.31501S.08L
Radio a try too.
good to hear no negative results got my phone unlocked so i will be testing tonight. also do u guys have the newer sims or older ones?
I have an older sim I believe. It is one that came from an activation kit I bought off ebay. I tried the T-Mobile radio and same results, still on Edge, but still could be my location.
What in gods name are you guys doing! ? Are you trying to brick your phones? It's already been confirmed that the hardware on this phone does not support the proper bands for T-Mobile 3g!

It's not just the SOC that determines hardware compatibility. There are various radio amplifiers and filters which are tuned to the specific frequencies that the phone is likely to encounter. If a phone is going to be sold in multiple markets, sometimes the hardware filters are set up for all frequencies and some are disabled via software, but often times this is not the case.
It's not impossible that a radio reflash can make it work, though highly improbable.

Interested in this. There might be better luck flashing the tmo radio since I don't think any European operators use AWS bands, correct me if I'm wrong.
Can anyone explain why flashing this radio from a different device won't brick our phones?

I have a tmobile one s, but i also have the one from att and i am so interested on using this phone over tmobile 4g let me know if i can of help. I am using my micro sim that came with the one s and i am getting edge (asume its the latest from tmobbile 4g mucro sim. I am on 1.85 rooted but i did not unlock. though i am sure we can flash through CWM. any ways i am sure there is a way out to get 3g or 4g on the one x on tmobile did not find the way yet.
flashed both of the t-mobile modems no luck for me either, although my ping is significantly higher and connects to t-mobile a LOT quicker.
does anyone know how to edit the LTE settings. it is odd but for most ATT LTE phones they have the 1700mhz frequency i think it would be a matter of just defaulting that....
the radios also show up in my baseband so i have successful flashes
EDIT: one more thing, before i was not able to use data at all considering i had the newer t-mobile sims but now data works but on edge speed.

it's just a file in your system. it could potentially brick your phone but you can always get into recovery and restore. which is why i stated you should create a back up of your device before trying it out.
however, i was fairly certain it wouldn't do that because the internals of the One S/One X are nearly identical, they both share the same processor and most likely similar (if not same, radios).
either way, the the radios work, getting me higher ping, and working data without having to switch out my sim for an older one, hope there is a way to activate the 1700 band !
http://www.gsmarena.com/htc_one_x_at&t-4614.php
EDIT 2: apparently there are two models of the ATT One X/XL one with the 1700 band and one without

Likely the software has been changed to support T-Mobile, but the hardware (filters, amplifiers, etc) are non-existent, so you'll never get actual 1700 MHz AWS support.
Of course, this is just a 50,000 foot view perspective without actually trying it myself.

you might be right about this one but there are certain One X/XL's that do have the 1700 band found out through some searching and trying to figure out the reason behind it.
If that's correct.... the people with the 1700 band would have 4g when they flash this radio! also use *#*#4636#*#* to change network type to lte/gsm
--- for other phones though like the Skyrocket/Note they were directly compatible with T-mobile radios.
Okay, I flashed the Tmo One S radio and did not receive a brick. What I did receive is a not-so-good connection that will switch between HSPA+ and 3G quite often.
I don't have a WIND sim to test with, but I tried running AT commands on my phone and they don't seem to be working. I tried doing a network scan with AT+COPS=? waited forever and had nothing displayed.
Strange...

Rebooted and ran the commands again. Still don't see any AWS carriers.

Don't you need a wind sim to connect im pretty sure the Canadian version will work on aws
Confirmed on my end that even with the T-Mobile radio, I'm not getting HSPA+. Even when I drove by the Moscone center where 1900Mhz was refarmed during Apple's WWDC (maybe it was just that day?). I was hoping this would be like the Note and Rocket where I can flash different radios.
Any other new phone capable of this? The S III? If not, I may have to either wait for 1900MHz refarm or switch to Straight Talk.

Picking up an att s3 today to test it out. Most likely there's two versions of one x one with aws and one without. I know mine doesn't though.

I'm not exactly sure of this one.
If someone is willing to let me cut up their WIND sim (or lend me their WIND microsim), I'll re-flash the tmo radio and meet you somewhere to test it (Toronto, please).
~dan
-----edit-----
Just popped in an old WIND sim that I used to test AWS connectivity at first. Saw WIND Away with the standard radio, and after flashing the Tmo radio I see WIND Away and AT&T (AT+COPS=? shows Rogers, ATT, Telus, Bell).
I live by the lake, that would explain why ATT shows up.
-----edit again-----
Check this out http://imgur.com/Nb984,rUvM6. Not using the One S radio...
Of course, i don't have a clue how to :laugh:
I ask the community here if its possible, for the carrier T-Mobile, to add basebands to the Samsung Infuse 4G
Its very possible as the tech is closely related... but you have to program the modem... correct?
If this isn't possible..even to gain some sort of band... root... any sort of way to gain more then 2G speeds with t-mobile..yes im using att phone and yes its unlocked... im willing to do whatever to get better speeds xD...and not switchover to att..
It is my understanding that if you flash an improper radio you will hardbrick. Have read this in the N1 forums and would guess it would apply here. The problem is more so the different bands that T-mo uses vs AT&T. Others more knowledgeable than I hopefully will post. Regards.

Possible...yes-chances of it happening...most likely not
People are asking the same thing over in the vivid section (one guy offering a $100 to the first dev to accomplish it) after a little reading...I've found that "bands" are not really bands...its just deep coding that basicly tells what frequencies to use per channel and all that...it requires software hacking to the extreme...only very extremely expierenced/knowledgeable devs and Samsung themself would be able to do it...
Here's the vivid thread http://forum.xda-developers.com/showthread.php?t=1807740
And here's a link to another thread http://forum.xda-developers.com/showthread.php?t=1548553 (that was in the vivid thread op) with a guy explaining how it is possible and proving everybody wrong that were saying its impossible
Now...I can't be positive its possible but after reading that guys arguments I'm convinced it is possible...but only the experts would be able to do it...

I saw that the Binaries for GSM/LTE were posted, but didn't see anything for CDMA. I can't find the thread now, but I recall reading a post where somebody mentioned that AOSP ROMS wouldn't be fully functional on N5 phones on Sprint's network. Does anybody know what I'm talking about? If you do, please elaborate. I want to slap on AOKP or CM 11 once they are available. Since this is a Triband device, I hadn't consider AOSP ROMS would be an issue using Sprint.
It's disappointing isn't it ? Developers ignoring a genuine question because the lot if then don't care about CDMA even though it's a nexus and their supposed to improve upon the device and they completely alienated sprint users on aosp Roms. They refuse to even acknowledge LTE not working on aosp roms and don't even treat it as a bug.

I have had the ****s of CDMA anyhow -- I'm tired of the locked down mentality. I use Ting (and love their service), but they use Sprint as their backbone and, just once, it'd be nice if I could use any damn phone I want simply by popping in a SIM and adjusting the APN settings. I think I need to try a decent ATT MVNO for a while. I returned my nexus 5 and will try again in January. The audio issues caused by software and manufacturing goofs are unacceptable to me. I'm more than happy to switch to a GSM Gnex for now, to get away from CDMA.
Is there a list of AOSP ROMs that will allow full functionality on Ting (or any CDMA network, if they're all the same)? Are there viable alternatives?
On my Galaxy S3, I ran a Touchwiz-based ROM to work around the issue. I don't mind using the stock ROM for now, but I'd like to know if I should just look for a new MVNO that won't cause these headaches.
Hey guys,
I have been noticing, ever since the MM update came out earlier this year, development has slowed to a crawl for this phone. There are a few roms that look really nice, but are not really good as a daily driver, as some have missing functions such as Phone and Contacts, and other stuff is glitchy. But over on the international G900F forums they are overloaded with different great roms with tons of support and updates and all that good stuff. And looking at the difference between the Sprint G900P Galaxy S5 and the Unlocked variant (The G900F in particular) they have 95% of the same internal components, with the only difference being the Modem to communicate with the CDMA (Sprint) and GSM (every other carrier basically) Towers. This is the reason why the roms will boot, and everything will work perfectly hardware and driver wise other than picking up a signal for the Sprint Users.
So what I am asking is if there is a Developer out there who can compile a flash-able zip or something alike that includes the drivers for the Modem and sprint Libs. Or even if there is someone who has a background in this that could point me into a good place to start, I would be glad to do it. What does everyone think about this?
my question for you is why do you want this? I only ask because i was running MOAR 7.0 for my trip to Romania and Bulgaria this summer. I spent 2 weeks in a town 5 hours northwest of Bucharest and tons of town around Transylvania and a week down by the black sea in Bulgaria and my S5 was working perfectly on vodafone, never had an issue at all. Im domestically sim unlocked, but that shouldnt matter as the SSU apk should get you internationally unlocked and ready for use abroad. That being said, none of the international ROMs would give you an unlock for international or domestic use.

I think you read the question wrong (perfectly fine, i didnt really word it very well on my part). What i was asking is if there could be a universal patch to make the Sprint LTE and Messaging and all that good stuff work on an international rom. I think it is possible as there is currently something that is exactly that, except for Verizon (the G900V variant).

Oh, my bad. Well, sprint lte isn't going to work overseas. To get lte, you'll need to do quite a bit of finagling with an nv calculator, qpst and qxdm. You'll first need to fine out what bands the carrier you'll be using utilizes, get the nv figures that they run on and make some changes to the modem you have installed on your phone. That involves getting into the diagnostic port of the device and, well, there's a whole thread devoted to exactly that. Anyways, hspa+ will work without too much effort, and hspa+ is pretty dang snappy. Messaging will work right out of the box after registering on the GSM network(+1 to gsm ) MMS and data will work also once you've entered the correct APN settings. If you REALLY need lte, then you're relegated to some tweaking, but if you can live with 5 to 7 Mbps(which is all a phone really needs, unless you're tethering for a laptop or several tablets or something like that), then just do the hspa+ thing. I was happily able to tool along quite well on that streaming YouTube, Netflix, Google map navigating, etc etc without issue. The reason there isn't a universal fix is because it would take quite some doing to maintain an app to have all those apns and so forth, but that being said, the idoneapps apk does do that for the available gsm carriers in the states. I didn't use it abroad, but might be worthwhile to ask in their forums. The admin of that site "nodial" is an Android genius! Their app costs $35, and it won't add the lte bands, but if the lack of hassle is worth it to you, it couldn't hurt to ask him. He's on XDA also with the same nick. @Nodial, does your app do the APN fix abroad too?
