I am trying to find solid answers on this before I do it, but can't find any evidence it will work, and without issue. I just want to gain my T-Mobile wifi calling, and be able to use IPv6, but the ROM that my Note 3 came with, does not allow any of this (APN protocol is perma-greyed out and of course no wifi calling).
So here's what I have: Mexican N900W8
The ROM I want to flash: N900T for T-Mobile. Stock ROM.
Can I just simply use Odin and just flash it without rooting or anything since both are stock ROMs? Or do I still need to root it?
Also, if it will just flash right over, will my phone identify itself as a N900T and get over the air updates for T-Mobile, or will it ID itself as a N900W8 still, and possibly have future update problems?
Lastly, will all the other hardware work fine without issue? Wifi (most important obviously), NFC, etc?
Thanks.
I tried looking for this kind of cross flash but could not find anything whatsoever concrete that re-assures me this will work.
I would really like an answer for this.
Can I cross flash a stock ROM or not, and in this case N900T to N900W8 without any wifi issues?

You can flash 900T ROMS on the W8, however, not via Odin. Has to be done via Custom Recovery and you still have to flash the W8 kernel for it to work. - Essentially yes, You have to root, but I don't think you can get your T-Mobile WiFi calling unless you have an actual N900T.

As radical said, you can flash it using custom recovery.
It will show up as N900T instead of N900W8, but you can change this using "build prop editor" from the Play Store.
You will not get any OTA from T-mobile, custom ROMs don't get official OTAs.
I went and got a N900T then from T-Mobile. Have a N900W8 for sale now.

Is there anyway that I can install T-mobile firmware on my N9005 Galaxy Note 3? I tried to do it but it fails everytime. is there any way I can change my model number or something so I can install different firmwares from different variants? I ask this because I used to own a HTC One and I was able to change the model number so I could install different firmwares.

The better question is you have an international model so what is your goal? Are you trying to install a specific ROM to enable features (like modem frequencies) which have been disabled? You cannot install another model ROM on your device or you will just go into a boot loop or soft-brick your device and you will need to go through a recovery process. I'm going to assume you want to install a ROM for a specific feature or set of features which can be done but you simply need to ROOT and find a compatible ROM with the features you require.
Hope this helps!

yeah I was going to see if I would get LTE speeds if I'd installed the t-mobile firmware. also I want to be able to use Wifi calling as well. but the main reason I wanted to try out t-mobile firmware was, so I could get LTE speeds.

I've seen people saying they have a baseband for GSM and another for LTE. Where can I see this? All I see in "About phone" is "Baseband". It doesnt say specific for GSM or LTE.
And How can I get different basebands for each radio? In baseband collection thread all of them are just 1 zip file, so it updates both, right?

I see .zip packages that are supposed to upgrade GSM modem to one specific version and LTE to other version at the same time. Where can I check that?

Thank you!
I was thinking that as well, but in Omega ROM's thread there is a zip file that flashes a modem for GSM and another for LTE
**If you are having the old bootloader XXUB flash GSM_Modem_XXUEMJ5_and_LTE_Modem_XXUBMH1.tar file with odin by selecting phone.
**If you are having the new bootloader XXUD flash GSM_Modem_XXUEMJ5_and_LTE_Modem_XXUEMJ5.tar file with odin by selecting phone.
That's why I'm asking.
Any idea?
You shouldn't need to touch/flash another LTE modem unless you have problems, the one already on the device should work just fine. I don't know specifically what might be in Omega rom to require those instructions as I've never used it, but I'm running XXUEMJ5 GSM modem with the 'old' bootloader on Foxhound 3.1, and everything is working as it it should. I've never touched the LTE modem/the one that was on the device when I bought it is still on it & LTE works fine in areas where my carrier has LTE coverage.
If you're about to flash Omega rom, I'd say follow the instructions (or ask in the thread), if you're not, I (your mileage might vary though, obviously) wouldn't touch the LTE modem at all unless you have problems with LTE connectivity, WiFi or sound.
Edit - Going back through some posts/threads I have bookmarked from months ago, people who messed around with non-HLOS.bin files seemed to have a funny habit of borking their WiFi & other stuff. As I said above, I wouldn't be flashing one separately unless you had a good reason to (I.E something like the Omega thing where it's a specific instruction as part of flashing the rom), or flashing a rom/something else borks your WiFi/LTE/sound or whatever as I said above, the one already on your phone should do the job.

thank you vey much, but....
too late hahaha I've read your post right after flashing that zip. Everything seems fine but can't test LTE yet because my plan doesnt support it. I'll try to upgrade to LTE this week and I'll search for a method to revert LTE baseband if I need it in the future.
Thanks again sir.
I'm unfamiliar with Samsung phones (never had one), and I'm looking at getting a used/mint Galaxy S 4 for my wife. Here are the requirements:
1. SIM unlocked. I need to be able to use it on AT&T and T-Mobile networks in the US, and also other international carriers as need be when traveling, without a problem.
2. I need to have root access. Some apps that need to be installed on this phone requires root. It's not necessary to have the capability to flash custom ROM, etc. so stock ROM (or any ROM, for that matter, as long as it's stable) is fine. I just need root.
3. It has to have at least 4.3, or if possible 4.4.2. OTA capability for further update (if there will be any) is a good bonus but not required.
I likely won't be modifying this phone (flashing ROM/mods/etc.) after I set it up the first time. I'll set it up, give it to her, and forget about it.
So, which version of GS4 should I look for in ebay/swappa (and if there are any firmware requirements for easy rooting)? I'm going to be using it almost solely on a GSM-based network (currently a T-Mobile MVNO, but may switch to an AT&T MVNO soon) so AT&T version seems like an obvious choice, but I've heard that this model is a pain to SIM unlock (is it true?), while Verizon version is factory unlocked completely out of the box, and will work without a problem on AT&T or T-Mobile (and obviously overseas as well).
Can anyone give me any suggestion?

Yeah I deserve that. I basically set myself up to get this answer. This is what I get for not being clear enough from the get go. Doh.
Obviously the international unlocked version is the most ideal, because there's no potential for headaches as I explained above. I of course knew this.
And yes, there are several of them available at Swappa, but they are all (understandably) much more expensive (some more than 150%) compared to the local version.
So, I guess my real question is whether I should get AT&T, T-Mobile, or Verizon version for my purposes above.
I also just examined the title of this subforum and realized that I may not be asking this on the right place. So, sorry about that. I'll switch over to the correct forum and ask this again. Thanks for answering!
Hi,
Currently I have a i337 galaxy s4 which I am using with tmobile sim card. I made it unlocked by ATT before I switched to tmobile. It has baseband UFNI1 and Android 4.4.2 installed. I managed to get it rooted using the Odin software, so I can use the tethering with the tmobile.
Now I am trying to find a way to use the Wi-Fi calling. I searched it a lot and figured out that I need a tmobile rom installed but it quickly got very confusing. It looks like what you need to do also depends on what android version you are using. For some you need safestrap, change the kernel for some you don't. For some you have Wi-Fi issues and need to change the modem etc.
So, I am trying to find the easiest and safest way that will make the Wi-Fi calling work. I don't necessarily need the very latest android version or the fancy custom roms etc,I only need something that will work without any issues. I am perfectly fine with a tmobile stock Rom if that's the most convenient way.
So,I would really appreciate if someone can help me on this. It would be great to have a set of noob friendly instructions. Thanks a lot.

Hi There,
Were you able to root your device for Wifi Calling. I followed the instructions of http://forum.xda-developers.com/gal...nvert-i337-to-m919-wifi-caling-t2896719/page6 and went into the same issue. After TMOBILE stock rom, the phone does not boot. I was able to install the first rom and then able to get onto the latest version and able to use phone again with AT&T latest software update (android 5.0.1). Actually, this is the version I have when I started rooting.
If you find any solution, please let me know as I am on the same boat with you on installing TMOBILE ROM using the other thread.
thanks

You cannot install a T-Mobile stock ROM to an AT&T device. Samsung has safeguards in place to prevent it. You would need to root and then install a custom ROM, which on an AT&T is difficult to do with its encrypted bootloader.
However, this is not the appropriate location to ask this. Questions related to AT&T devices belong in the AT&T S4 forums.
Hello everyone,
I'm a long-time member but seldom poster; owned several Samsung/Android devices in the past and rooted/installed custom ROMs in all of them, so I'm a not a newbie, have read the FAQs, searched, etc. I just got an I337M on my Fido renewal and was somewhat overwhelmed by warnings about requiring different approaches to rooting depending on the basebands, etc. Anyway, I have a couple of questions I did not find adequately answered and I hope you guys would be so kind to help.
In the course of composing this post, I took the plunge to root using CF-Auto-Root and install TWRP 2.8.3.0 - I guess Knox is now tripped and the warranty on my week-old phone is gone - oh well. Next on the agenda is to:
1) Unlock my phone;
2) Try to improve cell reception with a different modem (I have noticed I seldom have more than 2-3 bars while I have 2 other different devices in the same room on Koodo with full signal strength);
3) Flash @Danvdh's awesome 5.0.1 Lollipop GPE ROM.
My questions:
1) To unlock, it seems I have to downgrade to 4.2.2. first. @veryluckyguy suggests to get the MDJ ROM and only extract/flash the modem.bin and follow the rest of the instructions. Does the modem.bin get flashed over with any new complete ROM I flash or are they separate things? Will I lose the unlock when I flash a new ROM?
2) Are modems generally interchangeable across Android versions? For example, can I flash a 4.x modem in 5.0?
3) Anyone have experiences with poor reception on Fido/Rogers and solve it by flashing in different modem? If so, which?
Thanks for all help.
Like you I was on Fido and switched
1) To unlock I simply used online service for SIM unlocking. Cost $20
2) I am using a 4.x modem in 5.0.1 GPE ROM
3) I cannot answer your 3rd question as I simply switched service.
Hope this helps
I'd recommend you to not try any software related unlocking methods, they tend to give problems with some sim cards lately. requesting an unlock code with your imei is the best and safest way to unlock.
Thanks for the advice guys. Part of my wanting to do this was as a learning and tinkering experience. I could take my car to a garage to have it repaired or hire someone to do home reno work, but like most members of the site we are tinkerers. I don't have an immediate need to unlock my phone, so I'll wait for now until I have more time and maybe unlocking procedures/tools become more mature and robust. I'm happy that my phone is now rooted, TWRP'ed and 5.0.1 GPE'ed without having bricked it .
I'm still going to try to flash a different modem to try to get better reception.
Thanks to all the amazing help here!

If you're still willing to unlock, consider flashing stock MDJ, rooting, then unlocking with RegionlockAway. From there, you can work your way back up to GPE 5.0.1 and the unlock will remain. I'm my experience, modems can be Odin flashed across Android versions, but compatibility discrepancies may subject the device to overall instability (ie. bootloops etc). I have found though that the modem from stock NC1 allows for Rogers LTE in 5.0.1.
Long story short, I was in a similar boat, but thanks to the help and advice from the members and contributors on this forum, I managed to find the solution. Here is a step-by-step. Good luck
