I just ordered my sprint galaxy nexus and I'm curious as to whether current cdma ROMS (cooked for the Verizon galaxy nexus) will work as is our will need to be ported?

I would think so, because most ROMs/kernels (that I've seen) are compatible between the GSM and CDMA Nexus phones, so I would think it would be the same for the Sprint version. But I'm not a dev, so I'm not 100% on that.

The rom's are different versions...not the same that can be flashed for either.
And no, they won't be compatible from what I've heard.

If the device repo on AOSP is correct and complete, they will indeed be compatible.
No the Verizon galaxy nexus usually needs a different from than the GSM version

sprint is not GSM, it's CDMA just like VZW.
if adrynalyne is right, they should be cross compatible

Without going into too much detail, how would they be compatible when they use different radios and towers and such? Especially when sprint launches their LTE in like 2020 or so. I would also assume that we would be able to use the same hotspot hack as well? I don't know how roms work, I just know I like them

Because when you flash a ROM, you aren't flashing the radio/baseband.

I won't go into much detail. When your Sprint phone roams you're using Verizon's network.

Thats cool. I figured it would be like say a computer and a usb modem. You can have them both but if the computer doesn't have the drivers for the modem it will not recognize the modem.

Yes but LTE doesn't roam.
I thought that also, since these are two different phone (GSM /cmda) it might have different radio frequency?

Verizon and Sprint both use CDMA and LTE. Neither use GSM or HSPA+. They'll be the "same" hardware. The only differences we see now is that they're operating on different frequencies.

The difference between the two will be the hardware lte modem and the baseband software. These are independent of the rom.

I'd imagine there would be a slight amount of tweaking involved still. For example, the ROM includes the build.prop which makes reference to the specific carrier. But whatever the differences are maybe a flashable zip could be easily created to convert ROMs made for the VZW Gnex to the S'G'Nex.

As long as you flash a 4.0.4 rom it'll be fine the AOSP code already has sprint nexus references so it'll run fine. The CDMA development section will encompass Verizon and Sprint nexus

Yet. They don't roam yet. It wouldn't shock me to see Sprint work some kind of agreement with Verizon to get LTE roaming.
Is the sprint version compatible with the Verizon network? With some unlocking or something?

The frequencies are different. And Verizon/Sprint won't activate phones of each other's networks anyway even if they were compatible.
So there is no way to change said frequencies? And thank you.

I honestly haven't really looked into it, but as far as I know, the LTE/4G radio is different, but the CDMA radio should be the same. So, if you can find someone at Verizon that would be willing to activate a non-Verizon phone (extremely unlikely I would say), then you should be able to get regular, non-LTE Verizon service on a Sprint device, assuming the firmware was flashed properly. The guys in this thread have made some progress on CDMA devices.
you could, but you wouldn't have 4g. The same way you'd flash a verizon nexus to cricket, you'd flash it to sprint. There are already small mods out there to get a sprint g'nex to operate on verizons bands, so to me, that proves the hardware works. The only thing wierd about the sprint version is its embedded sim. Its worth a shot, but good luck getting anyone to do the leg work for you.
Interesting. I might have a few connections at Verizon Wireless retail stores. A friend of mine, his mother works at one. So I might be able to get her to activate it.
Its not as simple as just activating it. At Verizon, our 4g phones are activated by the sim, not the imei. If the sim is not in Verizon's system, it will give a sim validation error.
Even with 3g phones like the iPhone, if the imei is not in Verizon's system, it will give a device validation error.

Just... buy a Verizon model? Why would you take a Sprint model and gimp yourself to Verizon 3G, dealing with the hassle, when you can very simply and cheaply buy a Verizon one with LTE and absolutely no hassle.
Will the switch to LTE in 2013 (I'm assuming to facilitate the MetroPCS merge) impact us Galaxy SIII users negatively? Does our device support an LTE functionality?
Also, if there is to be a switch in networks, would I be able to "switch off" LTE --to the lesser 3G-- to preserve date usage?
It won't impact us negatively. Heck it could even help us as it would lessen traffic on the hspa + bands as more people switch to LTE. And no our devices cannot use LTE.

I guess in a sense of it clearing the roads,it would be okay. It's too bad we wouldn't be able to handle LTE. Are you sure it isn't able to be activated via an update?

I'm probably going to have to agree with you, unfortunately. However, T-Mobile recently sent a pamphlet to me with a provided "FAQ" section, claiming that all of their devices will be able to support the LTE. I just didn't believe it, hence the thread's conception. It wouldn't surprise me if I had missed the fine-print-three-font saying "*this excludes the Galaxy SIII". It's still a glimmer of hope, though.
I'll continue researching the matter.
All of their future devices maybe. As of now, the only phone T-Mo has that is LTE capable is the Note 2.
As stated, T-Mo will still support HSPA+ as well as they do now. Gives T-Mo the edge over AT&T from how I see it.

Our devices may be able to support lte depending on the frequency T-Mobile uses for it.
Sent from my SGH-T999 using xda premium
Here's a pic to kind of show what the network will look like after refarming and LTE deployment is complete. Our S3s or any other phone that can use the 1900 band shouldn't take any performance hit. In fact, as newer devices are released with LTE support (and after deployment) it will reduce the number of hspa+ devices, leaving even more bandwidth available for hspa use.
It has been confirmed and questioned a number of times, but the T999 radio is not capable of using LTE. Besides, LTE is still far enough off that most of us probably won't see it in our areas till after we've upgraded to a newer phone.
But in the meantime if your areas been upgraded to hspa+42, you may already see speeds that rival current LTE offerings by competitors.

Not sure which forum to post this in. So here it goes.
I bought an unlocked AT&T Note 2 and using it on T-Mobile. I decided to open it and see what it was about and noticed these solder points.
Has anyone seen these points on there phones and done anything with them?
I've flashed a stocked T-Mobile ROM to the phone to get the features that a T-Mobile Note 2 would offer except the modem and getting LTE.
Those look like the different model numbers...
i317 is at&t T889 i think is the tmobile and im going to extrapolate Cana as Canada or the i317m
Not sure what they would do though. Maybe something to do with the radio. I cant think of anything that is inherintley dfferent between the models but might be to enable different bands or something

I'm going to desolder that i317 point and solder the t889 point and see if I can flash a T-Mobile modem with success.

Well, my experiment didn't work. I flashed the T-Mobile modem and it booted up, the Baseband said it was "UNKNOWN", then after about 2 minutes it would reboot and keep rebooting after a few minutes.

Are there any traces on the other side of the PCB for these points? If not... Then the only difference between them is the radio module. And these points are only to id the destination of the board.
Why make three boards if all you need is a different radio module and a dot of silver to make an id in the factory.

After further investigation of these points, they are connected to one another. Used a VOM to check continuity.
It's just for identification purposes. Oh well, worth a shot.

Those points are for the wireless back plate that Samsung was suppose to release for the note 2 but never did. You can find a thread in the n7100 of a user who jerryrigged a wireless charging solution.
As for using your phone on tmobile, why not follow the tutorial readily found to unlock the AWS band instead of just flashing a modem and possibly bricking the phone?

I guess you didn't read the whole thread? Those aren't for wireless charging, identification purposes. All of them are connected to each other, like a common ground.
I already flashed a T-Mobile modem and didn't brick the phone. Already did the AWS band thing.
Sorry I did miss what you wrote. I think those points are carrier identifiers before the software AWS unlock came about. So if anyone has a stock at&t phone and desoldered the point and soldered together the t889 point and stuck in a t mobile sim, I guess it would work fully on the AWS band.
Sent from my SGH-I317 using XDA Premium 4 mobile app
No problem. I do get UMTS3 and it switches to HSPA+ 15 and its slower than UMTS3 most of the time.
I'm sure I did the AWS unlock right. When I found those solder points I was hoping to be able to get LTE like our S4 does but, I don't.
I took the sprint training today for sprint spark and in the training it states that tri-band phones will have issues connecting to most current LTE networks and will receive an update sometime early 2014 to resolve the issue..
Just thought I would pass this on if some people with the Sprint G2 have noticed this issue over other LTE devices.

Good read. Very informative. But what about the device upgrades I was told about. In the training it says the G2 will have an update early 2014 to fix this issue and allow the g2 to connect normally to all available lte networks. From what I was reading it sounds like that would not work that its up to sprint to update the old LTE towers to support csfb which is needed for triband phones.
I'm either not understanding this fully or getting conflicting reads.
Sent from my LG-G2 using Tapatalk
This is really random, but I know someone who sells the towers to many carriers (including Sprint), and they told me Sprint would be switching to/releasing TDD-LTE (currently US carriers use FDD-LTE). This isn't something that the average person could tell the difference between, but it could mean a better network for Sprint in general in the future. I don't have a time frame or any more info than what I've mentioned; just that it's coming.

I'm by no means an expert, but I'm fairly sure that the 2014 update you're referring to will enable all three bands (25, 26 , & 41) on everyone's handset and has little to nothing to do with CSFB. That said, you can already activate all three bands via ##DATA# provided you have your MSL,and getting your MSL is very easy with this device.
Edit - Some people in Spark areas have already managed to connect to bands 26 & 41 with their G2 using the above method.
