Hey Guys,
So, I bought a AT&T LG G2 phone (I had a gift card at Best Buy- they don't carry T-Mobile). I heard that AT&T had the same towers so it's easier to work with an unlocked phone through them, so I bought it there instead from T-Mobile itself.
However, now I realized I don't have some of the features I would have on a T-mobile LG G2, such as my wifi calling, etc. Now, since the phone is unlocked (and I just got it rooted), would installing a T-Mobile rom affect my phone in any way, good or bad? Should I only use AT&T roms? How would I use T-mobile app services?
I searched google for 2 days and couldn't find anything relevant to my question. I've used this site a lot in the past year-two for rooting and such. Thank you guys in advance for continuing to support open development for android.
Wondering the same, about to switch to tmobile.

Well, seems like no one has an answer to it...
Anyway, I went ahead and bought the phone. Since I do a lot of testing and rooting myself, this was the first time working on this type. I'm glad you posted, because I would have just forgotten about it now that I've solved the question I had... However, I figure it'd help in the future in case someone is also wondering the same.
Now, with that all stated... down to the answer.
If you bought an AT&T phone, and do an unlock code to use it on another carrier (such as T-mobile since they use the same towers), the rom you MUST use are the AT&T roms... NOT the T-mobile roms. The problem is, when you buy a AT&T phone, unlock it, and root your device to use another rom, it will not be compatible with T-Mobile roms because of the image files, etc. So yes- you will be losing all the features a T-Mobile rom would have such as wi-fi calling, etc...
However, a way to go about this (and it won't work with ALL the features that comes in a T-Mobile phone/rom), is to install a AT&T rom of your choice without all the crappy AT&T bloatware that you can't even use, and go to the T-Mobile section to look for an APK version of the files. Most of the time, T-Mobile roms will also remove the bloatware, however, some developers are kind enough to provide the bloatware APK files in case users would like to have certain one of them features, such as WiFi Calling.
So, that's how I did it, and it's working good.
PS- One last thing, you may have trouble going on the internet or playstore when you're unlocked to a different carrier. All you need to do is find the APN settings for your carrier. So in this case, I bought an AT&T phone, bought unlock code to use on my carrier T-Mobile, and got the T-Mobile APN settings set up, reboot, and I get all my 4G data, etc. You can get this by calling T-Mobile. Just say, you bought an unlocked phone and can't access data, internet, etc, and was told to set up a APN. Or, you can use google. :good:

So, would I be correct in stating that you will only get 4G in areas where it is offered @ 1900 MHz? What about 2100 MHz? Otherwise you will only get 3G HSPA+? As you can tell I'm a bit confused about compatibility between networks. According to wikipedia they will be doing away with 1900 MHz 4G by 2015. I'm trying to decide if it's worth buying an AT&T or Verizon phone to use on the T-Mobile pre-paid network because it seems the T-Mobile phones are not getting very much development.

hey johnny, so you were able to get wifi calling feature on at&t branded lg g2 unlocked?
AT&T phone switch to T mobile Wifi calling do not work

Bought phone from ebay, it is an AT&T phone unlocked and want to use for T-mobile./ With T-mobile network I have to use wifi calling features in order to use in the house.
Could you please explain me how and how much it cost to get wifi calling feature in LG G2 ?
Ok,... a NOOB question.. (ok.. three questions) (and yes, I have looked around, and I did not see answers to my question… or i was too dim to understand it….. :/ )
Question 1)
I switched from AT&T to T-Mobile. my Note 3 is is unlocked, and rooted.
This is probably a silly question, but When I look at “ROMS” and “MODS” for my phone, should I be looking for an “AT&T “ phone? or a T-MOBILE” ?? is there any actual HARDWARE difference?
I have a SM-N900A (branded AT&T) … does that mean I can not use ROMS that are for the T-Mobile note 3s? or do I have to only use ROMS that are for the AT&T note 3?
Should I just sell my AT&T note 3, and buy a T-Mobile Note 3 ??
I would like to get rid of the AT&T bloatware… especially since I am no longer on their network.
I am not trying to go over the top with my phone, and I would like to be able keep the s-pen features (but I have to admit, I still need to LEARN how to use it better!)
Question 2)
I just tried to use my hotspot on my Note3, and I am gettingan "invalad sim" error...
I am guessing that I do nto have enough of the AT&T stuff out of it?
Question 3)
Another “feature” that I would like, (maybe a second question/thread?) if about tethering.. I have unlimited data on my phone, but as I understand it, they will only allow 2gigs as a hotspot. I think I read somewhere that some ROMS combine the two…
Thank you for any advice…
Danny
Okay, I can help you with a few of your questions...
Q1. Since your phone (the service provider doesn't matter, the hardware does) is ATT, you will need to get your Roms and such from the ATT area.
ATT, in all their ridiculous glory, locked the bootloader on our phones, and thus we have to SafeStrap in order to use roms.
It's a little wonky, but it's almost as good. Our development is growing and more roms are getting ported over every day.
But if you want more control over your device and can afford it, I would personally recommend to switch to a TMo device.
As for removing bloatware, most of the roms are pre slimmed, and you can fix the rest by freezing apps with TiBu. And you can still do that without losing the TouchWiz and SPen functions.
Q2. The Invalid sim issue is likely because you have a TMo sim card in ATT software. There's a Tether Provisioning app that can be frozen to prevent that.
Q3. I'm not too sure how TMo handles it's Tethering monitoring. You'll have to ask that in the TMo note forum.
I hope I could help you at all. =D

I have decided to buy myself a T-Mobile Note 3, and sell my AT&T version...
I had rooted my (using Kingo) about a month ago, to fix the GPS driver problem... But that was ALL I did, after rooting it... and I think this week, AT&T sent out an update (mandatory... cause I never saw it!)... which not only broke my "root" ... but broke my GPS again as well.
So now I say good bye to my brand new, with the EXTRA insuarance plan from Best Buy phone, and start looking for a used Note 3 that is not bootloader locked
AVOID AT&T

I caveat by saying the forum would not let me post anywhere but the general forum right now so that's why I'm posting here.
I've read a bunch of conflicting threads and info lately but nothing concise in regards to what I'm trying to do and need some help.
This is my first ever android phone. I'm coming from an iPhone 6 as a heavy business user. WiFi Calling is extremely important because my house has terrible cell reception. I recently purchased an SM-G935FD (duos phone) and I'm a USA AT&T customer. I rooted the phone day one but had not yet swapped the SIM card. I chose the DUOs because I do quite a bit of international travel and I liked the hardware of the XYNOS platform better than snapdragon. Unfortunately I didn't realize or suspect that WiFI calling would potentially become a problem. I could care less about Samsung or Apple Pay for that matter, nor do I really care about Voltos. But wifi calling is a deal breaker.
I rooted the phone, and I put flash fire on there but really don't know how to use it. I found some people saying that my phone can accept both the SM-G935F firmwares and FD firmwares, but others who were skeptical. And people saying that there were firmwares that did have wifi calling enabled and others who said no.
At the moment I am back on the iPhone 6 because the Samsung is useless to me until I figure out how to get wifi calling enabled on there.
So... I'm confused. IS there a firmware I can flash my rooted unlocked S7 that will enable this? How exactly do I go about doing that with either flash fire or smart switch? I looked, but I am having difficulty finding a guide on doing this. The phone is already a paperweight, but I don't want to brick it as well lol.
Thanks for the help.

Actually I think I got it figured out. I changed the CSC using TWRC over to an att USA CSC and that seems to have at least enabled the menus for this functionality. I haven't moved the SIM back over there to test it though.

I would move this thread to the AT&T specific section. My understanding is that specific drivers are needed to do WiFi calling on AT&T and it's not baked in and the model you bought is not sold in the states whether it's sim unlocked or not. Also, why would you root/jailbreak a phone running an OS that you have no real experience with? If you can't get it to work then I'd return it and either buy the AT&T version outright an have them unlock it for you or go to Best Buy, Amazon or Samsung themselves and buy the single sim unlocked version. You may still have issues with that unlocked version if AT&T's Wifi calling is as locked up as I remember. T-Mobiles wifi calling works with your handset but it also has oddities such as the TMO sim must be in sim slot 1 to work. Because that model is not normally used with U.S. carriers .. they kinda don't give a crap about it so the work is on you.
Since this is your first Android phone .. I don't want you to think this is a problem with the OS or even with Samsung. It's just how things work. Apple allows carrier specific network files to be pushed to iOS where that's not the case with Android. I think maybe backup and stop hacking on things would be a good piece of advice. Take it for what it is. I just would like to prevent another iOS switcher from running around saying Android suck because things didn't go the way they thought would.
Cheers.

Ok slow down. I don't think any of that at all regarding saying or
Thinking android sucks nor would I make such a conclusion. Lol. Also couldn't put the thread there, wouldn't let me create a thread over there (said im "too newb")
I'm a LONG time older comp sci major who works for a software company and has been doing consulting for a number of years. All day every day I deal with every software imaginable. It just HAPPENS that this is my first android phone, and Therefore is not that familiar to me yet. The only reason I had an iPhone and idevices (all jailbroken) in the first place was because at the time, my company was locked to Apple mobile devices. I'm actually simultaneously working with piemessage to try and get a VM up and running to allow me to use iMessage on Android
Also I understand their may be some nuisances of screwing with other packages and drivers. I did do the CSC update and that "enabled" at least the menus and the ability to turn the features On. Whether or not it's working, I have no idea. Without a SIN card inserted however, I was able to place a cal using google hangouts dialer without any issue whatsoever, but as that is a different app then the actual phone dialer... I'm not sure if that proves anything. Feel free to correct me if I'm wrong, but making a wifi cal through Hangouts Dialer connected to my google voice number without a SIM card inserted is different than dialing a number using the phone app.
Unfortunately, the only real way for me to test it, is to take the SIM back out of my iPhone, call att again and have them switch the IMEI again. At least google voice wouldn't configure properly until I did that and it took forever to get the call forwarding reset. And my problem is I'm going on a business trip tomorrow and don't have the time to be swapping SIM cards back and forth.
Maybe I'll just put it in letter without calling AT&T and see if it works anyways. Are there any prevalent icons up at the top to indicate it's a wifi call being made vs a cell call?

Yeah, ya never know what folks know.
I've just encountered a lot of folks who are smart techies who have used iPhones for a long time and Android frustrates them and then they freak out. My bad. I apologize.
I still think you need to check the AT&T specific section. I've read that the proper support for AT&T's wifi calling isn't baked into AOSP like T-Mobile has theirs baked in. This could have changed but I don't think so. The other calls ie. Hangouts, Google Voice and Skype aren't controlled by AT&T so I would assume they'd work regardless. The wifi calling registers with AT&T's servers/routers ... what they require for this handshake I'm not entirely sure. I know that when I tried it out using my Nexus 6P it didn't work out of the box but I didn't spend a lot of time on it either.
Ah. I get you about the business trip thing. It's why I bought the unlocked S7E .. I have to swap to often when traveling. I did this after I bought the version you have. I found that 1 sim slot would do LTE/3G/2G and the other was stuck on 2G only and that it would random switch from sim 1 to sim 2 when I was in the States with my personal TMO sim and my work AT&T simcard. It was too irritating so now I just expense the TMO account and gave back the AT&T sim. Not an option for everyone .. I get that.
Also, I did read that AT&T likes to jack folks around on speed when it's not one of their phones and there is a fix involving the EMEI number being changed in your account .. I can't remember where on XDA I found that trick but I'm sure a search will find it for you.
Hope you get it working. The S7E is a nice phone.
Safe travels. Cheers.

What was your result? I'm in the same boat, thought this model would be useful for business trips. Also need Wi-Fi calling at home, but no dice.
I'm kind of newb at this S7 stuff, I'm more of an HTC guy. Yesterday, I bought an unlocked G930P (sprint) and am not sure, but think I learned that normally, people don't change out the ROMs to use a different carrier, they simply unlock the phone and live with the old carrier's bloatware. I started reading up, and first learned that TWRP apparently isn't available on a Snapdragon processor, so the G930A, G930P, etc, aren't candidates for TWRP. At first, I was kind of dismayed. Then, I found the G930U ROM and on a whim, I tried punting the G930U ROM to the G930P. I bought the phone off craigslist, and he said he didn't know where HE got it from, but it was unlocked. Anyhow, the phone took the rom without a hitch and now it looks like a U model...
My goal: Go with T-Mobile. Use Wi-Fi calling. Eventually have Nougat. Remove bloatware, but possibly keep some nice T-Mobile add-ons, if any, because I don't have their service yet (I hated ATT's crapload of stuff). Note this isn't specifically a "TMobile" question, substitute your carrier of choice for the questions...
Get to the damned question, you say? Ok, here goes:
1. I'm not going to ask any "do these bands work" when moving from a P model to T mobile. You guys seem to fight about that stuff until you can't type any longer. I'm going to assume what whatever bands work, that's what I get. Unless I get a T-Mobile specific phone.
2. But I will ask this: do the over the air bands it uses depend on the baseband ROM that is on the device? This is something I can't figure out.
3. I heard T-Mobile uses an updated boot kernel (3.0?) and ATT & others use an older boot kernel, and that if I move to T-Mobile boot kernel, I can't go back to any of the older ones. This process I seriously don't understand. Can I run a T-Mobile OS (or any OS) while using an older boot kernel ROM? I would think NO, right?
4. I don't like all of Carrier X's bloatware. I'd rather use a stripped down, cleaner ROM. I guess there are apps for that, but is it cleaner to do it with a stripped down generic ROM that I see floating around?
6. Speaking of ROM's - I saw a lot of Xetheros or whatever ROM's floating around, but it seems like there aren't any for the snapdragon-based ones. Is this true? The posts on this site don't really talk much about the snapdragon-based phones and why there aren't any ROMs for them, and why it won't work, and what, if anything, is being done to get around this. I guess the G930U is Samsung's answer to that, and allows fooling around with roms, but will the other phones ever be actually rom-able, or should I ditch this G930P and actually buy a G930U? Now that my phone THINKS it's a G930U, did that get me around some weird barrier and NOW I can update other funky roms intended for a G930U?
I'm considering selling the G7 I just got and going from a G930F (now that I'm a bit wiser). Any common sense why not to do that? I already HAVE an ATT G7 (not the sprint one I just bought), but it has a "bad signal". It gets only about 1 bar indoors, on a good day. I took it to a repair facility and they said, "nothing wrong with the antenna, it's your mainboard, don't bother just buy a new phone". Anybody have any advice on that?
thanks

All U.S. models are built the exact same and will all accept each others firmware if done right , so any unlocked s7 you put the U firmware will essentially be a g930u other than the number stamped on the back , I dont believe the U firmware supports wifi calling or VOLTE , There is a t-mobile nougat firmware floating around if you want to try that , your att g7 if it has a hardware issue should be under warranty but if your using it with a different carrier I would flash the appropriate firmware to it and see if that fixes you signal issue and if not put it back to stock and call Samsung , as far as switching from the international model , Well i bought a international edge as soon as they release and it took a crap on me within 4 months and I was unable to warranty it , that was my only issue with using a international model but also i dont think you can get wifi calling on those either . hope that helps
edit* and yes the bands are dictated by the rom , U firmware opens all of them otherwise carrier roms unlock specific , and T-mobile nougat dowgrade back to MM will be dictated by the baseband , I know the Sprint nougat can be downgraded but not T-mobile for sure

I don't believe those features are supported on AT&T (probably at AT&T's own request). Perhaps that might change in the Nougat version but I wouldn't bet on it.
Hello all,
Like many others, I unknowingly bought a blacklisted phone on eBay. It's a Samsung S7 with T-Mobile from the US. I live in Costa Rica, and I'm trying to use a SIM from a local service provider. Sending the phone back for an uninteresting list of various reasons is impossible at this point. So, I am attempting to unlock it.
I rooted the phone with SuperSu thinking that would work, now I know better. After hours and hours of research, I found a xda dev that can remove the lock, but with my slow internet speed, he says it's impossible.
I was suggested to use one of the paid services, but I'm concerned that if my slow connection will not work for the xda dev, why would it work for a paid unlock service? My connection is 5/1. Anyone have any luck buying the expensive @$$ service and successfully receiving the code with a slow connection?
Is there really no way around the T-Mobile Unlock App?
Is there truly no DIY process or program that I can do, being that the paid unlock services may not to work?
I really need this phone to work. I just moved to Costa Rica, and I use my phone to work. So, I am pretty damn stuck between a rock and a hard place with spikes. I'm pretty desperate, almost willingly to pay my last money to a dumb unlock service.
But some of the services say that it will not work if the phone is blacklisted.
I just don't know what my options are at this point.

Might be able to resell the phone with a *disclaimer* that it is blacklisted, I would recommend Swappa over Ebay though, (I got a really decent chunk of change for my Galaxy S Blaze that I sold on there), and then use the proceeds from that to acquire a phone that isn't stolen.
I got mine unlocked in a repair shop at gaffar market,delhi,india for rs 3200 inr and it was blacklisted on tmobile's website, when bought it was unlocked but after few days it automatically got locked to tmobile.
I mean to say if i can get it done in india you guys can also get it done in your countries.
You would have to do a firmware swap - which you could do yourself - you just won't be able to use it on that particular carrier, even via an MVNO on that carrier. My own S7 is ex-VZW (network locked); but I could take it to T-Mobile (and did) via firmware swap. My carrier (Tracfone) uses both VZW and T-Mobile towers ; while VZW was out, T-Mobile, however, works fine. If you sell the phone post-swap, include documentation that a firmware swap was done, so the buyer does not try to take it to T-M by mistake - some folks insist on following the labelling unless expressly told not to. (My S7 still has VZW labelling.)

Firmware swap? So you're saying you can take a Note 4 on T-Mobile that is blacklisted and you can fix the problem just by flashing a new firmware from AT&T? Am I understanding that correctly or no? Because I have a Note 4 that is on T-Mobile that someone left at my GF's work and never came back for, so they wanted to throw it away, so I took it, I rooted it, deleted all the bloatware and have it working great as a small tablet, but I can't use it as a phone because it is blacklisted. Been trying to find a way to use it for years now with no luck, I will not dish out any money to one of those sites, I don't trust them. If there is a way I can do it myself I would surely try it.
Indeed You Can

A blacklisted IMEI only affects the blacklisted carrier in question - it does not affect ALL carriers. (I cannot take my Snapdragon S7 to Verizon or that side of Tracfone due the IMEI being Verizon-blacklisted; however, it does not affect T-Mobile or the T-Mobile side of Tracfone - which is a separate network/carrier - which is why I was able to take the phone there.
. In your case, your Note 4 has a T-Mobile blacklisted IMEI; therefore, you can take it to AT&T Mobility, Verizon, the Verizon half of Tracfone, or Sprint - you simply need the apropos firmware and SIM. If the phone itself has T-Mobile labeling/branding, and you are trying to sell it, you should include documentation indicating what was done, and why (honesty). The biggest issue is sellers that DON'T do that (document what was done) or worse - don't do a firmware/ROM change for a phone with a blacklisted IMEI. So you can actually use it as a phone - you just can't take it to the original carrier.

This is what I am saying - that and a SIM from a carrier other than the one that blacklisted the IMEI - I took my own phone from VZW to T-Mobile (Tracfone supports both carrier networks). Because it was an internal swap (same MVNO), it cost me nothing.
