[Q] Questions about unlocking and more.

I have an iPhone 5 and I'm on AT&T and have it up for trade.
Someone has a tmobile note 2 and wants to trade
He said he can get them both unlocked. And the tmobile will work fine
On AT&T.
My questions are will it work and if I want to flash custom Roms will this mess up the unlocking?
I have searched all over and can't tell some people say everything but LTE works and some say not.
It's confusing. I need the phone to work on AT&T and not have to worry about messing up the unlock.

It should still be unlocked but you should get the code just in case.

Once it's unlocked, it's unlocked.

Just make sure that note is fully paid for or you may end up with blacklisted phone

I would just say, not sure specifics but who in the right frame of mind would trade away a GNII for an I phone 5... just sounds 2 good to be true, especially with all the horror stories out there...

[Q] Enabling T-mobile LTE on an AT&T Note 2

Have an AT&T i317 unlocked with a T-mobile data sim.
I've done the tweak to enable the 3G/4G bands, a la http://forum.xda-developers.com/showthread.php?t=2068041
But now T-mobile added LTE in a few markets. I drove through one and suddenly got no data access. This is with "preferred network mode" set to LTE/WCDMA. If I switch to GSM/WCDMA, all is well (it sticks to the HSUPA and H+). So clearly it thinks it's on LTE but the phone can't access the T-mobile LTE.
I'm using Cyanogenmod 10.1, android 4.2.2, which also makes the model number show GT-N7105 instead of i317.
any tweaks to add the LTE? do i need to dump CM and use a diff ROM? do i need to go back to stock first to do any of this? (Right now, I can no longer dial *#7284#)
Thanks!

I am having a similar issue, I have a sgh-i317 with aws mod and the phone is not picking up t mobile lte even when placed next to a sgh-t889 that is getting it. Lte works with att sim but not working with tmobile sim. Any help would be great. I have tried many roms and modems and reflashing aws mod. Roms inculde jedimaster13/14 jedi x13/14 both att and tmobile versions and clean rom and stock 411 and stock 412
I figured it out see

Does the AT&T version have LTE? If it doesn't have the capability, but he modem is telling it to access it when it sees it, that might be why it dropped out completely. I'm mostly curious to see if AT&T LTE devices can use t-mobile's LTE network because I want to get an s4 active and I don't want to lose LTE by making that switch.

Try this for me, instead of that model number you have. Change it to the T-Mobile model#. Which is going to have to b done thru the build prop. Then reboot. Then go try and c if you pick up lte.
Because I just flashed a AT&T Rom on a T-Mobile GN2. And I pick up lte just fine with my AT&T SIM in there! And no AWS MOD what so ever. But the MODEM is still TMO, it'll always b TMO. Flash a att modem on a TMO GN2. Brick city.
Let me know what happens just curious!!
Edit: the Rom I flashed was SKY NOTE 9. No modem included!!!

I don't have any solution for the question but I do have a question of my own.
Why do I keep reading of people buying att devices for t mobile, why not just buy the t mobile version?

WELL, here's your answer.
Maybe they getting the device at a cheaper price. Which would make someone but it. Instead of spending a lot more to have have the carrier brand you need. FYI
Both the phones are exactly the same. Besides the model# and done bloat. Like I said above, if it's unlocked it'll work, with both carrier's. So why not have that option to switch... and one more thing being able to take the phone internationally, and pop a SIM inside and ya have service. No roaming !!!
Just my 2¢® 2 you're question...

Att now has prepaid lte plan almost same as tmobile only .5 gb less of data everything else the same at 60 dollars . Plus att has better coverage well at least in the areas I frequent .

When a t-mobile version is available, I do buy it, but with ATT exclusives, that's not an option. For instance, I want the s4 active for its water resistance. T-mobile will soon offer the xperia Z, but when you compare the features and perormance, the s4 active is better, so for the money i'm willing to spend on a smartphone, i'd rather have the s4 active.. the hardware is capable of t-mobile LTE, but it still has to be configured properly with firmware and software to use the radios correctly. Since radios are some of the hardest pieces of firmware to alter, it's worth doing this investigation / collaborating to find work-arounds.

I didn't get tmobile lte on my at&t note 2 until I flashed the new at&t radio. That's all that had to be done. I'm using Skynote9 too. I did the aws mod again so I could get h+ 4g speed enabled and now is a flawless tmobile phone. Let me know if it works for you.

MetroPCS Version

I have the MetroPCS (SGH-M919N) version of the S4. I don't see a specific forum for my model. I was wondering, since T-Mobile and MetroPCS have merged, can I use the same instructions on this forum to root my device. Thanks in advance.

Truthfully, I was wondering why the MetroPCS version didn't have its own forum.
The S4 is particularly important, since it's the first MetroPCS smartphone to use T-Mobile's GSM network instead of their standard CDMA. You can use your S4 in places where you never had MPCS coverage before -- in Portland, Oregon, for example.
The next place I'm going to look for comments on the SGH-M919N is in the T-Mobile forum, since we're already using their network anyway.
The standard T-Mobile version of the phone seems to be called the SGH-M919 (sans N).

Let me know if you find anything. I'm dying to root this phone and get rid of all this Samsung and MetroPCS bloatware, thanks.

Well as far as the S4 all the S4 and even the international quad core version are the same phone. So you wont have any issues there. And as far as not having it's own forum. XDA dont use lower class carriers like MetroPCS and Cricket. You could go to AndroidForums.com they have metro pcs phones in there

Thats not true at all. If they were all exactly the same they'd have one root method for all the devices.

I was able to root my metropcs S4 using the instructions for the T-Mobile version. But now I can't see the contents of my SD card. The funny thing is when I install CyanogenMod, I can see it just fine. The Sd card seems to not be mounting in CWM or in the stock rom. Is this a permissions issue or what? Any help would be appreciated.

If it wasn't all the same devices then people couldn't flash roms in between carriers and international. These are the same phone hardware. Only thing that change is the modem. Unlike the S3 where you can't flash roms from international but you can between US carriers.
And for root. On my S3 they had to get a stock rom Odin with root in there because it would striped the flash counter.

That's not entirely true. Most of the s4's are the same excluding the i9500.

You seem unaware of this: T-Mobile not only bought MetroPCS a few months back but are using their own network mainly -- not simply MetroPCS's -- for the Galaxy S4 currently sold by MetroPCS.
The whole reason I bought a MetroPCS S4 is because I can use it anywhere in the US that you can access the T-Mobile network and because I can unlock it and switch to T-Mobile if I like in three months' time.
Both T-Mobile and MetroPCS have confirmed this, and it isn't true for any other current MetroPCs phone.
Also: Most analysts have concluded that the introduction of a cutting-edge phone like the S4 is unprecedented for that carrier and is likely T-Mobile's idea.
The phone was was $100 cheaper than from T-Mobile and the monthly service is a lot less expensive (unless you can use Google Voice with a legacy plan on T-Mobile).
So why was it again that you felt the standards of XDA members were too high for them to use MetroPCS?
Oh, and the single difference in iterations of the phone itself appears to be one added letter. T-Mobile's S4 is the M919; the MetroPCS/T-Mobile version is M919N.
Those are the reasons I'm hoping that someone at XDA might confirm that this is essentially the T-Mobile iteration.

For people who've been wondering whether these iterations of the S4 are the same:
They really are.
Have a look at this conversation between a person rooting their MetroPCS S4 and a ROM dev for the MetroPCS S3:
http://androidforums.com/metropcs-galaxy-s4-all-things-root/740568-metro-pcs-gs4-root-sgh-m919n.html
the metropcs sgs4 is literally the same device as the tmo one with a new model number, after talking with the cm folk it seems they arent going to make a seperate build, just adding support to the tmobile one
when you install rom manager and tell it to flash cwm you can pick the tmobile/metropcs variant
thanks, and no there wont be any updates as far as you can tell, you are best off . . . installing it and choosing tmobile sgs4 as the recovery.
this phone is so tmobile they dont even mention metropcs in the apn's to connect to data :/
after consulting with the cm guys they arent even going to do a separate cyanogenmod build for the metropcs versions, you guys will be expected to flash the tmobile roms.
everything ive been told is use teh tmo cm10.1 builds (id hold off on 10.2 for now). make a nandroid, if it doesnt work out well revert

Son in the end, is it gonna get its own forum section or would any tmo ROM work with it? Correct me if I'm wrong but doesn't the s4 use MetroPCS' LTE and TMobile's HSPA+ 3G, thereby bringing the best of both, real LTE and high speed 3g?

I've had no problem using CF-Auto-Root method on my two metro S4s. Have rooted, unrooted, and rerooted a couple times without issues.
http://forum.xda-developers.com/showthread.php?t=2294005 post #2 is how you root metro s4.
Do you have latest version of Odin, Samsung USB drivers installed, and Kies turned off? If you have all these covered, it should be just downloading and flashing the CF-Auto-Root TAR file and done. Not sure why your phone would be bricked from this.

I know it is late but if you are still using metoPCS S4 then root is now very simple.you can do that with Odin.You have to download CF-Root file.Then just Flash it via Odin Flashing tool.Done!!

[Q] Tmobile Samsung S3 soon to be on Aiowireless, Which Roms?

Ok so I have just received my unlock code from Tmobile for my Samsung S3.
I have just ordered a micro sim from AioWireless since I have decided to give them a whirl and see if I would get better signal in my area (my signal has been blah for the last year).
So with that in mind, Do I still install roms from the this forum(s) and just change APNs or do I have to start using roms from the At&t S3 forum?
Just trying to figure out the best way to go, and most importantly the correct way.
Thanks in advance.

You can still flash ROMs meant for the t999 and change the APNs...you should also be able to flash AT&T Roms without an issue, just make sure the APNs are correct.

always flash for your device, not your carrier. just a good simple way to look at it i think

[Q] Using T-Mobile Note 3 N900T on Sprint?

I just SIM unlocked my T-Mobile Note 3. I have the opportunity to join a framily plan at $45 for unlimited data and want to test it out and see how coverage compares. Currently I'm on N900TUVUFOB6 running the Tweaked N3 3.95 ROM. Do I need to switch the baseband, or ROM, or do anything else special to get it to work? Or can I just pop a Sprint microSIM in and be good to go? I tried searching N900T Sprint but really didn't come across anything.

I'm guessing cause one (T-Mobile Is GSM) Sprint CDMA

It's not going to work. The bands are completely different in GSM and CDMA.
