Flash Tmobile ROM on AT&T or vice versa - Future Proofing the best!

So I've read thru many threads on here and found people that seemed to have flashed their tmobile ROM onto their AT&T device in order to get proper 3G+ speeds.
1) Does this actually work?
2) Is it better to flash the other way (if possible, AT&T rom onto Tmobile) in order to get maximum service from both phones? What is the best/better phone to purchase for future LTE future proofing?

I am also on the t-mobile Q&A section looking for answers... the best phone for future proof and LTE is the AT&T version... no doubt... now... I am waiting for an AT&T Stock Rooted WITH MODEM included in the same flash zip before I begin testing myself... I already ordered from ebay a dual sim card adapter for the Note 2, and the Note 2 is already unlocked... so... any news on this would be great...

I just flashed Tmobile Jedi X3 with my att note 2...all working perfectly....the steps I took was just to flash rom and one of our att kernels and youll be fine...didnt have to flash modem....just put my straight talk apn in done....Everything perfect...btw jedi X3 is super fast....:good::highfive:

Sounds like you might be in the same boat as me. Anxious to get a Note II but not sure which network to commit to with it. Your comment about needing to get a TMo ROM to get "proper 3G+ speeds" is disconcerting. It also pushes me a bit towards TMo since it's got the LTE radio promised for future update.
What exactly is wrong with the stock device's 3G+ speeds on AT&T?
Where I live and work (Los Angeles area - San Fernando & Santa Clarita valleys), LTE's not activated, and no firm date when it will come our way. AT&T's HSPA data speeds here aren't anything to write home about, but neither are TMo's when I tested one of their devices in the local shop. My AT&T phone is lucky to get 4Mb/s down, 0.2Mb/s up, and generally only about 2-3Mb/s down. The TMo Galaxy SIII I tested got 4MB/s down. Hard numbers to swallow when I've got an SIII on VZW LTE pulling down 20Mb/s in the same area.

Jedy 3 is an international rom, not T-Mobile with wifi calling... with 3.5G on T-mobile on Jedi 3? (HSPA+)

I need clarification on this. Just because the ROM flashed worked, doesn't necessarily mean the proper AWS radio's were activated to attain 4G speeds that are required on T-mobile (this is nothing to do with LTE).
Are you saying that by flashing the tmobile ROM onto your at&t note 2, you are able to attain all connections (not just Edge, but HSPA+ 4G) with your AT&T device to tmobile using AWS? I know Tmobile has begun refarming out to 4G on a different band that is compatible with more handsets, so you might just be in an area where they have already done so, which mistakes you into believing that you are actually connecting via the old school AWS Tmobile bands, when you aren't.
I really need to decide which phone I want to take the risk on - The tmobile LTE is locked apparently, doesn't seem to show as many capable bands as the AT&T version, and also, I'm not sure what to bank on in terms of there being a software vs hardware lock (Would be nice if the tmobile can be unlocked via software to fully operate on all LTE modes that the AT&T supports).
I'm actually in Canada, and would probably end up needing to purchase the Wind version in order to get what I'm looking for (since Wind operates on the same AWS frequencies as tmobile). But losing out on Bell/Rogers/Telus LTE in the process is just something I don't want to do either.
Going to have to see what can be unlocked via software on all these different phones................

I would also appreciate a response from someone if this is possible... using T-Mobile ROM and modem to work on At&t (with aws frequencies).... just like the S2 I717 mod which after flashing was working with aws frequencies....

Yes... it should... as soon as I get my dual sim card adapter for the Note 2... I will post a million results/combinations here on T-Mobile and AT&T forums... I just don't want to open the back cover 30 times a day and swap sims a bunch of times... with the adapter I just insert the 2 sim cards and done... testing all the way from that point on...

I have the SAMSUNG-SGH-I317 from AT&T, unlocked via unlock code from AT&T. No root, stock AT&T android 4.1.1. I got the t-mobile microSIM card with an unlimited talk and 2GB unlimited data plan, but I can not get tmobile 3G/4G working reliably. I get HSDPA/HSPAP/UMTS/EDGE randomly. 80% EDGE, 20% high speed between 4-8mbps down, 0.7-1.9mbps up. I am in Los Angeles, CA.
I know my SGH-I317 does not have the 1700MHz antenna needed for t-mobile 3G/4G data, but somehow I get 3G/4G 20% of the time. I have not adjusted any special settings on my phone, other than to reset the APN to default epc .tmobile .com. My guess I am getting 3G/4G via the 2100MHz antenna for download, but without the 1700MHz for fast upload, I get 0.7-1.9mbps only. But most of the time I am stuck at EDGE.
So has anyone gotten the AT&T Note II to reliably work on t-mobile 3G/4G? is there a special setting I need to enter on my phone? does flashing the t-mobile ROM on the AT&T phone solve any of the 3G/4G issue? or will I lose the unlock on my phone when I root or when I flash t-mobile ROM on my AT&T Note 2?
Any help greatly appreciated.

Hey I got a unlocked & Rooted At&t Note 2 on T-mobile running CleanRom with perfect 4g. Before I rooted my phone I changed my phones modem to T-mobiles because I only had edge. After that I have flashed several different At&t Roms and still have 4g. On speed test I get about 7-9mbs download and 2-3 mbs on upload not the best but way better than edge

You have the exact set up that i am currently using.I also have an unlocked At&t Note 2 SGH-i317 on T-mobile running CleanRom SE1.5. I absoulutely love it. I like the stock look with better performance. Are you using another Kernel? And im also thinking about flashing a new Rom what would you recommend? Im kinda looking for something Similar to Clean but better battery life. Any Suggestions???

I am actually using the CleanROM 4.5 (haven't flashed 4.6.1 as I do not see much new on that ROM). I am actually using it on the stock kernel because I am not a huge flasher like many of the members here. Since Note 2 is my daily driver, I don't want to keep updating it and customize it after each ROM flashing. I like the CleanROM 4.5 since it was the way I got it and I just updated to the new version. The battery life is pretty good as I can last a day or more with moderate use.

AT&T Samsung SGH-i317 Galaxy Note II LTE on Simple Mobile

Morning guys...
This is my very first thread on this forum so please bear with me if something was not done the right way.
Since I couldn't find an specific thread for this specific topic that's why I decided to post a new thread on this.
This thread will help you get a Stock AT&T Samsung SGH-i317 Galaxy Note II LTE phone with a stock ROM into Simple Mobile network with working 4G.
I can't guarantee this method would work on other Galaxy Note II models so please make sure your phone is exactly the same as the specs described on this link.
Also please be aware I cannot and will not be responsible for any damage this thread could cause to your phone. All I can say is, I tried this myself on my own phone and it worked for me and my only intention here is to share my experience to other users on my same situation.
So let's get into business!
Verify the phone specs. Please make sure your phone is an AT&T Samsung SGH-i317 Galaxy Note II LTE phone and that it matches the specs described here.
Get your phone unlocked. On a personal note this appears to be a must, so if you can't get it unlocked for some reason don't even bother moving forward down the list. I followed this thread to unlock my phone. Yes, the thread is for a Galaxy Note I, but it still worked for me.
Get it rooted. That can be done here.
Flash a stock T-Mobile ROM. That also can be done here which is the same thread as of step 3.
Enable AWS band. Is worth mentioning if you made it here successfully, then you already can use Simple Mobile just fine!, however you'll be stuck on 2G/EDGE unless you Enable AWS band here. This will let you enable 3G and 4G on your phone!.
Now at this point I'm sure you may be able to use another ROM of your desire, but I'm not 100% sure if that would work. On my personal recommendation I would first try the 5 steps EXACTLY as described above. Then if you still want to use another ROM, then you may need to repeat steps 4 and 5 with another ROM.
Now I also want to say, the credit is not all mine here. All I did was to compile the information altogether for you guys. Please don't forget to thank me, as well as the original thread owners compiled in this list.
Good luck in the Kitchen!

Reserved!

^^^Thanks, thread moved to general and stuck for easy reference.

Wait, You Menchtened LTE and 4G, And in which T-Mobile doesnt have. T-Mobile has 3G/3.5G HSPA+ but not 4G..

U dont need aws band on at&t phonez lmao noobs all u need is your phone unlocked and youll get on t-mobiles fake 4g .its cause t-mobile now shares at&t spectrum stop giveing people false info.

That is not entirely true sir. Not ALL areas have the 1900mhz Tmobile yet. You do need to unlock the AWS band for some areas to get the 4g. In my area (South Florida) they happen to have the 1900mhz 4g. I know because I sold an unlocked Infuse 4g (AT&T phone) to a buddy with a tmobile sim card and he got 4g on his phone.

Good information man. Ignore the OTHER GUY that is giving false information.

Everything worked for me, except one thing: CDMA VS GSM preference.
My CDMA signal is weak, so 4g cuts out. The phone just wants to default to EDGE as a first priority. How can I make CDMA the default preference so I always get 4g when available?

thanks!

I have a sgh-i317 with at&t radio uamc3 or something like that and jedi master 14 with aws mod. I also restored my friends nv item backup from his sgh-t889 with jedi master 14. I am getting the 4g bands but my phone will not connect to the lte bands of t mobile. is anyone else having this problem? I have tried everything to get lte includes odin to stock wich should allow me to connect to tmobiles lte but wont. other people are connecting with no problem. can anyonw help me think of more ways to fix this. or is this particular phone not support 1700mhzaws. I really dont get it as the specs everyware state it does. also when I select all lte bands and selct t mobile it say unable to connect, try again later. I put my sim in a s4 t mobile and lte works so it cant be the sim. I also put at&t sim in my phone and lte works so my lte chip/radio is working fine. is maybe the free unlock methode not unlocking my phone completely? any way to relock and do it with an an unlock code. franky I am puzzled. I am in an area getting t mobile lte, confirmed on both my friends with a note 2 and s4 from t mobile.

Running T-mobile on ATT note 2

Hello everyone.
I'm sorry if i write bad English because I'm not really good at it. Sorry in advance.
I have a ATT Note 2 which i bought from a friend and i unlocked it by using the free method from the forms.
When i first unlocked it my phone went to lte signal and my data was working fine and i was getting lte speeds.
I made a phone call which usually drops the single to HSPA+ aka 4g/3g but for some reason my phone doesn't go back to lte after.
I even called t-mobile they said they see my phone was on lte but they don't know why it's not going back to lte.
If anyone here running Tmobile sim in Att note 2 and still getting lte speeds after phone call is made please provide me some instructions as because I've tried everything possible i can from the forms. I've been trying for almost more then 3 to 4 months i still haven't found any solution to this problems.
If anyone can help me out that will be great.
Thank you and sorry for my bad English.

That's odd, mine is unlocked and I use Tmobile but I dont have those problems... maybe it's the modem, could be reception... sorry to head you're having issues dude.

I'd verify the APN and make sure you have the most recent modem flashed.

First things first, what solutions have you tried? If we don't know what you've tried it won't help much. Also what method did you use to unlock it?

If you used the free unlock then you have the J2 modem - that's the earliest stock AT&T modem. Since you were able to downgrade, I'm assuming you can upgrade too. Depending on your location (whether t-mobile is using the refarmed AT&T bands or using their own) you can use the latest modem or you can search for a t-mobile modem.
But speed is what matters, not what icon is displayed. Check the phone status under the settings menu to see the actual network type you're connected to.

Can't get my Verizon Note 4 (n910v) on T-Mobile. No service.

Hello everyone,
I was using the Verizon note 4 on tmobile until I got the 5.0.1 lollipop update. Now it won't register on tmobile at all, and there is an "x" next to the signal meter, indicating that it isn't getting any service. I triple checked my apn settingssettings, network modes, restarting. Nothing works. Did the lollipop update simlock the phone?

Anything is possible culprit..I would take out the battery and make sure the Sim card is inserted properly..and if that doesn't work do a factory reset..

Getting TMobile 4G_LTE Working Again
Hi,
I had the same issue with my Galaxy Note 4 (SM-N910V) edition. I needed to go back in and add the APN for TMobile US LTE, then all was well. I have included snap shots of mine for reference. Also, make sure you set your "Network" to Global.

In my situation, I'm a tmobile user but had the chance to get a verizon note 4 at a cheaper price. At this rate though, I may just sell it and get a tmobile version.

Has anyone figured out the issue?

I got another N910V with 5.0.1 today, it has the same problem (not being able to use other carriers' sim cards). I'm pretty sure the 5.0.1 locks the phone. WTF Verizon??

Sorry you're having that issue. I bought a Verizon Note 4 on swappa the other day that already had 5.0.1 and Build ID ending in BOAF. I was able to get signal on it, no problem. Downgraded to 4.4.4 and service was still available. Have your SIM card replaced at a Tmobile Store to see if that resolves the issue. I'm curious as to your APN settings and whatnot.

Sent from my SM-N910T using XDA Free mobile app

Well I can't say for sure either, but there are too many people having the same issue (no service on tmobile after upgrading to 5.0.1) to deny that 5.0.1 has anything to do with the problem. Also, the ones that are saying lollipop has nothing to do with sim lock, can you guys check if you're using 5.0 or 5.0.1? The ones that are saying that they stopped being able to use the N910V on tmobile are all on 5.0.1.
EDIT: If you're on lollipop + tmobile on a n910v, can you tell me if you're using the new ISIS sim card?

trouble with note 4 mobile hotspot
Need help, when my verizon note 4 was root, I was able to turn on xposed tether for mobile hotspot. I was able to connect other devices to it, but had limited connectivity meaning no internet. I tried everything but had no idea. I almost want to give up note 4 even love it. Is it because xposed tether does not work on note 4? I have same issue with foxi. Is sqlite editor better, can someone help me with setting for sqlite for Verizom note 4 to try? Thank you

Found solution.
For those having issues with not service when changing SimCards after 5.0x.
The solution is http://forum.xda-developers.com/android/software/debloater-remove-carrier-bloat-t2998294
Just disable Verizon activation (VzwActivationAgent apk) app. NO ROOT NEEDED
I also disabled some Knox services that where already pre-marked.
Now I have service with T-mobile Sim and don't have the annoying "unkown sim" message.
The tool is created by @gatesjunior so, show your appreciation on his thread.

I followed the instructions and also disabled "VzWActivationAgent.apk", still unable to get TMobile sim to work. Any other suggestions? Thanks in advance.

Samsung S4 3G issue

Hi guys
I’m new here and I need your help.
I have Samsung S4 International bought on amazon in US, no simlock.
I use this phone in Ireland in Europe.
Everything was ok until a few months ago when I lost 3g connection. Science then my phone is working in 2g only mode (gprs/edge speed)
Phone was running on stock rom android 4.4.2, I thought it is a software issue so I rooted phone and installed CyanogenMod. Unfortunately it did not help 
Phone still synchronise with 2g network instead of 3g even in capital city next to BTS.
I was wondering is 3g module broken and what could be a reason of that? Do you have any idea how could I fix it, what would be a cost of doing it and is it even worth it.
Except that, phone is working ok. GPS with finding a fix is a little bit slow but this is not a big issue.
Thanks in advance

Current details about phone:
