So since this device is coming out on three (US) networks as well as the developer edition. Let's say someone makes a ROM for the Developer edition of the phone, is it expected to be able to work on the At&t version (obviously after we can unlock the boot-loader)?
Or for example if someone makes a ROM for the T-mobile version, is it expected to be able to work on the Sprint version?
I'm just curious because if this is not the case, then i need to make sure i get the developer edition (I'm trying to avoid shelling out that much cash up front).

CDMA and GSM have always been separate roms. So the Sprint version won't be able to have ATT/Tmo roms put on it. The Tmo version supports the 1700mhz frequency and the Dev/ATT version doesn't but I am not sure that will cause a difference in the roms.

Hello xda, I was Judy wondering if any of you could help me out with a problem I'm having. I might be getting an android phone, the only problem is that I'm on us cellular and there doesn't appear to be top many options. My phone options are the htc hero s, Motorola electrify, Samsung repp, htc wildfire s, htc merge and huaweii ascend ii ( sorry if I spelled that wrong).
IM looking for a phone with some support of development community behind it, whether it be on xda or some other forum/ website.
Thank you and IM sorry if this its in the wrong forum.

They are CDMA so if may be possible to activate an unlocked Verizon or maybe Sprint phone but you wouldn't get carrier subsidized pricing so it would be more expensive and may be harder to activate.
Motorola doesn't want to unlock bootloaders while HTC has recently made it possible to unlock bootloaders on recent models. Unfortunately the US Cellular versions of any android phone are going to have less dev support because US Cell is a smaller carrier meaning less device owners.

I didn't know that, (sorry I'm a noob at phones). I remember when my dad broke his phone (some cheap thing), my brother's old phone was the same model, os he went into the store and they made it his phone without a problem. Do you think they would be willing to do that if I brought in an unlocked verizon phone?
Thanks for replying.
I'm not for sure if a Verizon phone will work, technology wise it has the hardware to communicate with US Cellular since its CDMA, but it may require some software changes to work on their network. Also it depends if they will activate non carrier devices.

Yeah they probably wouldn't allow it.
Hopefully at least one of these phones has some rom development somewhere on the internet, or I can get the wildfire and just remove sense from it without a problem.
Hey guys,
If this has been answered previously, then please forgive me, but I wasn't finding anything definitive in the related threads. I've got an unlocked Developer Edition that I plan on using on T-Mobile. I really wanted the extra space and I *believe* San Diego is refarmed and so should work reasonably well (although if I get Edge speeds I'm gonna be bummed).
Anywho, has anyone figured out whether there is:
1) any way to get WiFi calling working? Not positive I'll need but wondering if I need to flash a T-Mobile modem or rom to get that to work on the DE version
2) if tethering will work if my plan supports it (it does - I've done it on my T-Mobile Galaxy Note II)
3) does flashing one's modem cause the phone to show as "tampered" or "modified"? My preference would be NOT to add the bloat unless I'm going to lose out on the aforementioned features OR if the signal ends up being dramatically affected.
Lastly, has anyone else had any experience with the Developer Edition on T-Mobile in San Diego? Wondering what to expect.
Thanks in advance for any and all help!

To answer your questions.
1.Quickest is to flash a ROM, try this http://forum.xda-developers.com/showthread.php?t=2266025. Its stock (missing apps like calculator, flashlight etc due to bootloader unlock). It comes in odexed and deodexed flavors. There is a way to flash radios but I havent researched it enough.
2. Tethering will work once you pay for the add-on through T-Mobile
3. Im not particularly sure at which stage it changes to Tampered. But I noticed it after flashing a custom kernel. So maybe it occurs after unlocking the boot loader or flashing custom recovery. This does not affect the phone performance in any way that I know of. Im not sure what relevance this question has to the topic discussed tho.
Regards
I think the jury is still out on the question of whether or not the radio hardware is actually different between the TMo version and the Dev version. I, personally, don't believe they are physically different. HTC probably sat down with TMo and said, "by the time they get S-Off it won't matter anyhow".
Hi,
I'm considering picking up a rezound for the GSM flexibility but I'm having trouble wrapping my mind around how it all works. Is there a stable and convenient way to go between GSM/CDMA besides dual booting/rom swapping? What's the point of the new OTA if it's not even JB? And is s-off necessary for everything? I'm not confident in the risks involved...and the wire trick.
Sorry for the noobness. Thanks!

You do realize that switching between GSM and CDMA/LTE requires swapping out sim cards? You would need an AT&T or T-Mobile sim card to use a GSM network in the United States. So basically you would be paying for two separate wireless plans, one on AT&T and one on Verizon in order to switch back and forth. The purpose of the global GSM on the phone is so that if you go to say another country that only has GSM you could buy a cheap prepaid plan and insert the sim into the phone and be able to use the phone. And like myself who no longer has service with Verizon I can still use the phone as a GSM only in the United States by putting my AT&T sim card into it.
The phone once updated with the latest OTA will do this without being rooted or s-off. Verizon marketed this phone pretty much from the start as being a global phone right out of the box.
Yeah of course. I do a fair bit of traveling so I'd like the ability to jump to GSM on some foreign prepaid plan without having to purchase a secondary GSM-only device. My concern it's whether or not there's an easy way to switch without completely flashing a new ROM every time, or risking s-off (if it's even that risky?). Hot-swapping would be fantfantastic but rarely are things that convenient.
I'm not too keen on the OTA since it's not JB, and I usually go straight to custom roms anyway.

You should only have to swap out sims and change APN settings as the global GSM feature is built right into the phone now by default. There's noting you need to flash as long as you have the latest OTA update installed.

I'm thinking of getting a used phone, and I'd rather flash simply because stock Sense + bloatware is most likely terrible....unless the easiest way for global roaming is actually sticking with default software, which would suck.
Is there no convenient combo of custom 4.2 rom with some method for global roaming?

You would have to go into the development section and look at each individual custom ROM and see what build it is based off of to see if it had the gloabal gsm features baked in. I'm sure someone has already built a debloated custom ROM based off of the last OTA already. This is a spare phone I play with very infrequently and I don't use a custom ROM on it so I don't know which ones to suggest.
Android newb... will I lose anything flashing my unlocked international phone on AT&T
Hi everyone, and thanks for all the great info here. Let's assume I have my "how to root" links bookmarked and ready to go, but like a good boyscout I want to understand the gotchas/subtleties before I cliff jump. I'm also within my 15 days to exchange my s6edge AT&T for an unlocked one at Best Buy, which I plan to do today... :highfive:
(I'm technically savy, but a real newb in the world of android versions, manufacturer changes, and carrier versions and conflicts...) :crying:
1) How do I do a full ROM-level backup before beginning my adventures in rooting? Titanium Backup is no good since I need root to use it. I'd like an iPhone-style backup that I can just restore should I brick my phone.
2) After I exchange my phone I'm going to immediately airplane-mode it to prevent autoupdates (my current phone already autoupdated to unrootable OF4)... once I root how do I effectively get-latest? I'd obviously like the latest security updates, and 5.1 if I can manage it, and to maintain root.
3) AT&T doesn't have 5.1.... but if I go unlocked then can I run 5.1 on AT&T? (I've been iPhone forever -- carriers messing with you is really foreign to me). On a related note, can AT&T send some update/profile-change OTA to my phone that will conflict with updates I'm doing locally? If so any tips to avoid this?
4) An unlocked phone will perform just as well on AT&T as an AT&t phone, right? (looks like the 925F has all the AT&T bands and more, whereas the 925I is missing 1 AT&T LTE band)
Thanks for any info, help, and/or pointing me to resources where I can find the info, in advance. I'm technically savy, but a real newb when it comes to the gotcha-ridden ground of android and carriers.
Thanks again.
- Jason
So can I upgrade a 925F to 5.1 and use it on AT&T? I'm trying to work out if AT&T has _all_ edges locked down or just the official AT&T versions.

At&t does not have the power to lock down all variants; only the variant with its branding. Just make sure 925F is compatible with the network of you want to use that variant.

Thanks so much. Is there a reason I can't to seem to find any people running 5.1 or rooted phones on AT&T? Just that not many people are buying unlocked phones?

The at&t variant is the only variant not to receive 5.1 yet. It has nothing to do with root and everything to do with at&t's corporate policies. Most people who use a smartphone in the USA buy it through their carrier. So those users on at&t likely bought there phone from them. This is why no 5.1 for them.
I grabbed this phone (free) from Metro about 7 months ago. I was able to use their app to "unlock" the phone after 6 months. I'm unclear about what the official "unlock" will actually allow me to do with the phone. I haven't bothered to try to load a ROM or even root it yet--is this possible? The toggle to unlock the bootloader now seems to work, but I haven't bothered (yet). FWIW, I've rooted all my Nexus, Pixel, and OnePlus devices for the past decade (as well as loaded ROMs), but this is the first phone I've purchased that was carrier locked and I don't know what all that entailed. I honestly don't even know if the Metro variant is the same (as in bands, etc.) as the vanilla North American version or not. Hell, I don't even know what other carriers it might work with. I know I sound like an idiot newbie, and I guess I am with this phone. I've actually google'd quite a bit, but I just can't find much information regarding the Metro version of the phone.
Erm... what do you WANT to do with it?
Backup gets easier as root. Some don't care and real-time stream to the cloud.
Some are paranoid of what certain large companies *cough* Google *cough* might install on your phone in the middle of the night without telling you... unlocked bootloader lets you go to an OS build from AOSP or its ilk that allow you to see source code (if you are really, really, bored enough to check it all).
Some want to kill bloat (rather than just disable it).
Some may want to keep their phones for well after they are supported officially, with an OS like Lineage, or eOS (this not so much for Nord with a fixed battery, although I suppose you can replace it if you are determined enough).
Likewise, I have old phones I've turned into MP3 players for the kids- strip all the "phone" stuff and prevent connections to Internet/cell (eliminates the security threat of an old OS) and simply sideload AIMP, VLC, or whatever your favorite player is.
GSMArena has a very easily navigable feature list, that will show for some phones the different bands each supports- and you can compare to what your preferred carrier uses. USUALLY - but not always- there is an "international" version and a "US" Version. Verizon sometimes gets their own model with/for CDMA bands, but most support all the GSM Carriers and their resellers. If you are sim unlocked, you should be able to use them on any carrier, YMMV.
T-Mobile and Metro usually don't screw around with the cellular bands of the phones they sell, so the Metro/T-Mobile N10 does support the same bands as the factory unlocked version.
And you can start off by flashing the unbranded firmware onto the phone if you don't want the Metro junk and boot animation.
