The ability to do cool stuff with phones doesn't surprise me so I'm going to ask. I've seen it done going the opposite direction.

I think you can flash a custom .zip rom thru recovery then do some apn edits, but do not flash stock verizon firmware to your att device through odin. there is a difference!!

I am not 100% here but...
As far as I know the Verizon Note 2 works on AT&T and other carriers because in addition to being VZW device, it is also a world phone, meaning it has a GSM radio in addition to the CDMA VZW radio.
The AT&T Note 2 is a world phone by default due to AT&T being GSM so it only needs that one radio.
I do not think the AT&T version has the required CDMA radio in it to access VZW service.
I will do some checking and post back in a few.
**EDIT**
I checked the AT&T forum for the Note 2 and can not find any mention of a CDMA radio or anyone successfully using an AT&T Note 2 on Verizon.
**EDIT 2**
Verizon also gets to "approve" any device they let on their 3G CDMA network, so without some fancy hacking that we are not allowed to talk about on XDA.... you probably could not even activate the phone on Verizon.
^I believe you are correct...I was thinking the other way around not att on verizon.

I have an original ATT Note that was hacked to use T-Mobile with a Saurom Rom .....not sure which Radio....
My question is when T-Mobile releases their version next month can my original hacked Note be rehacked with the new T-Mobile ROM and radios?
Or do I have to restore the ATT files and sell to an ATT customer...then buying a new T-Mobile Note?
thanks for the help....

yep that's what I thought the answer would be....just hate to take a $ hit on it which I no doubt would...plus with Note 2 coming out soon it would be nice to be able to use the one I have with the real T-Mobile Rom and Radio....until the Note 2 comes out....

Is it because no developer will be working on it or what?
I dont think the t-mobile radio alone will help. But, if a replacement speaker/anntenna assembly becomes available, that should do the trick.
IIRC the phones are internally different. At least the antennas are. Thats the weak point of the at&t model. Personally id sell yours and get the one specifically madefor AWS. Plenty of people will want yours (LTE). Not everyone will want a tmobile branded phone.
Pretty sure the tmob phone will have superior AWS reception

Correct me if I'm wrong but T-Mobile is supposed to be rolling out with LTE next year, will the att note support that LTE since the phone supports it. If that's the case I will stick with the att note in hopes that I could get LTE.

Going to go for the T-Mobile Note
I guess I'm convinced that selling the ATT version and just buying the new T-mobile Note is what I'll do..............I figured that was the wisest thing from the start but was curious as to the "why's"........
I'm on T-Mo with the note too, but have come to the conclusion that I'll hold off for the note 2, assuming it comes to T-Mo, and if not then I'll get the T-Mo note later. I'm basing this on the marginally acceptable d/l & u/l speeds I'm getting and that 90%+ of the time my data use is on wifi anyway.
Just sharing another T-Mo users thoughts.
T-Mobile Note....Wait or Not
[My download and connectivity issues are such that without wi-fi dialing my service at home is unpredictable and marginal....so looking towards T-Mobile having their own Note makes waiting for Note 2 not a good option unless the ATT Note I'm using could be flashed again with updated radio and perhaps ROM.
Was hoping that taking those from the new T-Mobile Note would be possible, but if not then I'll have to go the buy-sell route and move my ATT version as soon as the new one is out and in my hands.
Even with this fix: http://www.xda-developers.com/android/galaxy-note-i717-hacked-to-work-on-t-mobile-3g4g/ you are getting poor results? I am thinking of getting a used note to use with my t-mobile 2 year plan, I will probably not going to be able afford the "no contract note" even if its released for t mobile soon...
I'm getting 3-10mbps average and that's when I'm NOT on wifi. I really see no reason to why you would sell your current note for a newer phone but with the sake exact specs at such a higher price. Wifi calling would be the biggest reason and 42mbps? Even with my galaxy s2 on T-Mobile I hit 5-12mbps all day. But I use data only for BS poker, Facebook and BS like that. I don't see at all why u would bother switching especially if its only to flash roms ans radios. Several threads talk about getting the tmobile galaxy note radio working on the att version.

Background: Work bought me an S4, but they use Verizon...I use T-Mobile. I must solve this issue. (Plus it's been so long that since I've even opened my QXDM/QPST that I almost...almost forgot how to use it, man, I miss it)...
This is more of a running log to potentially help others in their endeavors. This is an advanced topic...by today's standards. There is a LOT you need to know before just jumping in on this...unless you're like me and don't mind bricking a device for the sake of learning...then, carry on.
BTW, As you can clearly tell..I don't do super formatted frilly assed colorful posts...
ONWARD!!
What is known so far:
1. The modem MDM9615m is capable of anything...(Maybe even making you tea).
2. Using either 2009031920090615 or 2010031619780721 as the 16 digit PW in QXDM allows you to use "Software Backup" to backup and restore QCN files...(Both work, only one puts the phone offline)
4. The AWS band method that is floating around here (337_aws.qcn) doesn't work...it actually breaks the phone. (more on that later)
5. Putting your backup on again leaves whichever fields the 337 file had intact...so say you put the 337_aws.qcn file onto the phone, it stops working...however, you restore your backup...and the phone starts working again but all the fields of the NV that were written by the 337 file remain. Though phone functionality is restored.
6. MDK or ME7...doesn't matter at this point...no effect on functionality.
7. Flashing an MD1 modem/NV Backup from a T-Mobile Note II (which also has the 9615 doesn't seem to work...yet)...It actually kills the phone...I'll update when/IF I revive it...
8. You can Odin your modem back...whew!
What needs to be explored:
1. Whether or not flashing (shoehorning) another carriers radio will help (or if it's even an option)...this would probably have to be a regional carrier or maybe an international (non US) carrier's radio. Usually the bigger carriers can tell the manufacturer what to leave out/put into their phone...
2. Which NV Items need to be modified in order to get AWS (maybe even LTE) working.
3. Can a backup of another phone....let's sayyyy a T-Mo S4...be made and dumped onto the i545.
4. What complications are there? Is this permanent, can the phone be put back to "normal"? etc. etc.
5. If, as a last resort, we can edit the current parameters that are in the NV of a stock i545 to simply "reroute" (work with me here)...what bands it uses for which function...(this is the most tedious...but most undoable method...that I can think of....so far).
Troubles I've already ran into:
As mentioned before...after you write the 337_aws.qcn file to the phone it's pretty much set in stone...for now. When this happens, the modem starts boot looping...I'm sure this is due to bad parameters since the 337_aws.qcn file was probably from a 9215, i545 uses a 9615...you will not be able to access it again in QPST/XDM...
You'll have to get into Settings, More Networks, Mobile Networks, Network Mode, and select GSM/UMTS...this will keep the modem alive for you to be able to play with it again.
So far that's it. I've only been able to start messing with this phone in the past day or so...so, I'm sure this thread will be my dumping ground for my progress/findings/ideas...etc. Again, I encourage anyone that wants to help....to do so. I'm always open for collaboration.
This is where I start filtering down and organizing what I'm doing.
I believe that the best course of action right now is to utilize the 9615m radio from a Note 2...and perhaps a ROM from a T-Mo S4...
The main reason is because when you flash the 9615 modem but still use a VZ Rom...it tries to force it into a "WCDMA Preferred" selection. Which as we know...isn't an option in the menu. However, it's still trying...but I think the ROM doesn't know what to do at that point (could be way off here). I'm thinking that there has got to be a specific combination that needs to be used....for example...a Note 2 modem with a Tmobile ROM and NV backup? or that...but with a VZ NV backup...
I'm not a programmer/rom guy, (I'm more RF engineering etc...), so I don't know if there are things in the ROM itself that dictate which options are available and how the modem is used...
More exploration to be done...
Build.prop indicates to the system what network options should be available
Tmo rom looks like the way to go
On these newer phones the modem dictates pretty much everything else network-wise

That's good information....I tried running Paranoid Android but it wouldn't boot and any other rom told me that the device ID was wrong. I'm going to look into bypassing that check and try some more...
It hasn't been fully proven/disproven but it seems that there may be a "hard" block for US CDMA devices to use US GSM.
It can certainly see it but won't connect based on the threads I read.
But I don't think anyone has documented it in thorough detail what has and has not been tested.
Now if that setting is in NV data and can be modified... you may have a shot.
But if it's something hard coded and/or physical (QFuse) it may not be possible.
Q: Would it not be easier to find someone to swap with you? Or sell the device and get a Tmo?

Haha, leaps and bounds! easier, but what's the fun in that? How will we learn what can and can't be done if we take the easy way? Plus...maybe someone runs into a stellar deal and can't afford a full priced S4...they might nab a VZ one for cheap...this could potentially help a lot of people...
This is more to learn than anything...
Any progress?
Any progress with this? I'm in the same boat.
Thats a shame. Would be nice to have found out if a CDMA S4 could be fully used with GSM network.

HSPA on this divi e. Not LTE.
It makes me confused that band 4 LTE is locked on the phone
I always thought verizon had the open access regulation from FCC and that's the reason all verizon LTE phones are gsm unlocked
in fact some posts indicates it's CDMA unlocked also. Some CDMA carriers use R-uim card such as China telecom,and people were able to insert the ruim and have cdma working.
From this post, it seems verizon only had the regulation on LTE 700 band 17, not AWS band 4?
or is it just because verizon hasn't really deployed AWS LTE yet, so the relative software hasn't been released yet?

just for clarification, Verizon uses LTE 700 B13 not B17. According to Samsung and some other website Verizon S4 support LTE B4 and B13. and according to the guy in this post http://forum.xda-developers.com/showpost.php?p=44206677&postcount=20 he is using or have used VZW S4 on T-mobile LTE.
This is one of the oddest things I've ever run into.
I can put a T-Mobile Sim in the phone and it works almost like it was a Verizon Sim with the exception of needing to switch it to global mode when prompted.
If I stick a GSM Metro PCS Sim that I am currently using on the M919 it wont connect to anything except Wifi.
I hate locked bootloaders.
What about with custom roms?

Sorry that was a typo, yep att use b17 and vzw use b13
Verizon is going to deploy a second LTE network using AWS spectrum in congested areas
Why you guys don't install "android data tool" to be able to enter the *#*#4636#*#* menu so you could set LTE only to see if Verizon S4 pick up T-Mobile LTE?
If you are rooted and have access to write system data you could edit the "sale_code.dat" file under system/csc and change from VZW to SPR, AWS or any other code, so you can have more network mode options under mobile network settings.
Just for some clarification... This is done on Stock Touchwiz rom or is the device rooted and / or rommed and loki-d
Thanks,

So I can put a verizon sim card in my tmobile Gs4?I thought Verizon didnt use sim cards like tmobile and at&t.my tmobile Gs4 is unlocked so basically I just need a Verizon sim card and a Verizon plan. Thanks!!!

I don't think that works that way. Verizon is a CDMA carrier and T-Mobile a GSM carrier. Verizon sim card is for LTE only (LTE is GSM based technology). Voice works over CDMA radio which T-Mobile S4 lack of it. T-Mobile sim works on Verizon S4 because Verizon S4 is CDMA/GSM/LTE capable.

I have a rooted phone with jelly beans rom I am able to ADD Networks to the ROM Software also I can do it with HIAPN Software. But nothing works. What am I doing wrong. Its a Verizon i605 Note 2 which I would like to Try STRAIGHT TALK using AT&T Towers. I have tried 2 different At&t straight talk SIMS. Neither one will bring up SIGNAL on my screen. The last card I bought says for At&t compatibly phones or UNLOCKED GSM Phones. My phone is UNLOCKED am I imputing the wrong DATA in the APN Info area can someone help me here find what is causing my problem. Frank [email protected]
The only CDMA-based phones that work on Straight Talk are the ones that Straight Talk sells directly. The "bring your own phone" method only works with GSM (AT&T, T-Mobile) phones.

I just bought a brand new Verizon S4 that has never been activated on Verizon for $125. I am trying to get it working with a prepaid carrier in the US. I have been reading that it can be done with T-Mobile and ATT but am not sure where to start with this thing. For starters, the Android OS version is 4.3. I know there is an update out for it through Verizon. I can't do the update OTA with no Verizon service. I'd like to get this thing as close to stock Android/Samsung as possible and kill all the Verizon BS and then get it working on StraightTalk, Cricket, SIMple Mobile, or MetroPCS. Can anyone give me a good place to start or any tips. I've flashed ROMs before, changed PRLs, etc, so I'm no dummy when it comes to this stuff. The terminology/technology has changed some since I was messing with Boost Mobile phones. Any help would be greatly appreciated! Thanks!

Try searching.
You will need to ODIN to 4.4.2.
You will then need to root with "towelroot".
The phone should work with most any GSM carrier with the right setting. (T-Mobile, AT&T and Metro GSM).
Which will give you LTE, I can't answer.

I have used ODIN before when working with my Samsung Galaxy Prevail through Boost Mobile so I'm sure I can figure it out. Thanks for the info. I tried searching and found all kinds of different terminology such as SafeStrap and talking about the different bootloaders. It's a little overwhelming, but I'm sure I can figure it out. I did all of my original stuff through AndroidForums and there as a root section with all kinds of guides, FAQs, etc. Is there a beginners guide or FAQ for the Verizon S4?
I have read where I need to change the APN settings to get HSPA+ or 4G LTE with the different GSM carriers. It seems like HSPA+ is the best I'll get and that's through ATT. I'll keep digging! Thanks!
I currently have a VERIZON Galaxy note 3 that has a bad motherboard - I am being given a SPRINT Galaxy note 3 that has a busted screen / Digitizer.. but has a good motherboard.
I want to put the Sprint motherboard in my Verizon note 3 and use it on Verizon 4G LTE. I've been told the bootloader is unlocked, but that the sim is locked by Sprint and can't be used on Verizon or any other carrier, let alone 4G LTE.
Can anyone confirm or deny this? I want to use Alliance ROM (Verizon) and keep / use my 4G LTE. I don't care about any of the Verizon or sprint apps. I usually delete those.

Go ahead and give it a shot. Both phones are jacked from what you say so it won't hurt anything and will give you some knowledge on swapping internals out on the phones themselves.
Good luck and keep me updated on how it goes. Thanks.
