Umm... how? I don't think it's possible. Apparently you know a way but don't want to share? Also, iv wouldn't count on EVER getting good speeds in your basement. The bands TMo uses aren't meant for it.

I don't think you can

Of course you can flash radios. Why wouldn't you be able to?
Assuming, of course, you know what you're doing..

As long as you have a T999 model, you can flash any of the radios released in the dev section. Any radio on any rom. some work better than others but everyone has a different best one. Its up to you to test them all for yourself.

ddont know if this applies... but i used to flash radios, through my galaxy S (first generation), usually through odin, or a zip file and cwm... not sure how it would work for the gs3, but pretty sure itd still apply, if any method is best, probably through cwm as that shouldn't (in theory) affect your flash counter

Correct, though I personally recommend twrp. Just read the ops for any of the many released modems in dev section for more info.

[PATCH] *** N7105 AT&T and VZN ROMs on your SPH-L900 *** [N7100 works for ADV Users]

[PATCH] *** N7105 AT&T and VZN ROMs on your SPH-L900 *** [N7100 works for ADV Users]
DISCLAIMER: I am not responsible for anything that happens to your phone. You brick it, you fix it!​
This is a combination of work from scrosler and myself. I saw where Scott did this for the VZN GN2 and I modified it to work with the Sprint (SPH-L900) GN2 phones. With this modification your are able to flash N7105 ,AT&T (SGH-I317) and Verizon (SCH-I605) Roms to your phone. Both of those rom bases are confirmed working. Please make sure you do not flash modems/radios for the above listed devices. N7100 INT roms can be flashed using this method ONLY AFTER they have been ported to the N7105/i317 following madmack's guide in this thread. I can confirm that a port I just did of a N7100 rom works as well.
First download the SPH-L900 patch from HEREhttp://www.androidfilehost.com/?fid=9390248398092764671
Download a stock SPH-L900 kernel from the bottom of this thread -- Perseus kernels work as well, found HERE
Choose a N7105, SGH-i317 or SCH-I605 rom that does not install modems/radios - The Swedish N7105XXDLL1 4.1.2 stock rooted base can be found HERE
Follow the steps to flash below:
Reboot into recovery
Make a full backup
Perform a complete wipe (cache, dalvik, factory reset, system) in TWRP
Flash the N7105 or SCH-I605 ROM you downloaded
Flash the SPR_GN2_Config zip file
Flash the Stock or Perseus kernel
Wipe Dalvik/Cache
Reboot System
If you happen to do exactly what I told you not to and flashed a rom that installed a modem/radio and you no longer can get signal, if you didn't brick it and can still boot into download mode, you will need THIS FILE to flash in ODIN to restore factory SPH-L900 specs.
WARNING: Data may or may not work if you do not change the mount point for the DATA partition to the correct one in the updater-script!

Holy crap. Nice. The Galaxy Note 2 is truly universal. Thanks for this.

roms that don't have the modem.bin in the zip file. if they do, you can delete it and edit the updater-script and you should be good to go.

Sounds a bit too advanced and risky for me personally but kudos for letting this over for us!

It didnt work with the MIUI they have on ATT. ROM installed fine, but no data. I did the procedure in the OP step by step.
Possible cause - I think that even thought it is Touchwiz based, it uses MIUI base phone and framework (I am the one who got data to work on the port by lbx_mobbin_1 by tweaking the framework)

The zip replaces all the csc data with sprints....thats the main difference on these phones. Other than that, they are mostly the same. I have flashed a lot of crap on it from other carriers, so not too worried anymore.

Flashing non tmobile roms.

Edit: only issue across the borad is that theres no wifi calling. But nfc, data, mms, calls and text working. Incase people wanted to know but not willing to risk their phone being brocked, I've now successfully flashed a couple custom roms for every carrier including international roms. I installed rom, then tmobile csc files to get data and what not working and a tmobile based kernel. I'm currently using an aosp themed rom in the sprint forum, been using all day and no issues. Milage may vary, but I didn't want to point out its possible to flash all note 3 roms. Cheers

Good topic. I was watching a YouTube vid about flashing the international LTE type roms and it seemed to work fine just as long as you used compulsion kernel and some kinda wifi/Bluetooth/NFC flashable fix. I had a note 3 a while back and I'm getting a new one on Monday (super excited) so I'm really curious about this cuz I'd really like to have some more rom options. Is your mms working too?

Mms, data, tethering, wifi everything works. What I did learn though is that it's best to start from stock tmobile rom in our dev section then once that's all booted up go to recovery and flash the rom you want without wiping data then cc files and tmo kernel. A few roms wouldn't get data unless I placed a call 1st after rebooting.

Download Darthstalker ROM and pull the CSC folder from /system/csc/ then put it in the INT ROM of your choice. I do it this way since the CSC_TMO from miscom causes PHONE app to FC when trying to make a call. I use WINRAR to open and repack ROM files.

I have flashed virtually every 9005 rom out there - and as long as you flash the Blue tooth Wifi Fix file mentioned earlier (from the stainless rom post) everything works beautfiully well.
I also use a variety of kernels - Compulsion - saber - and a few others work fine.
I had also flashed several Verizon ROMS - Hyper Drive is awesome -
BUT, I have never needed to flash the CSC files - Flash Rom - flash Wifi Fix - Flash Kernel - reboot - all is good.
Just thought I would share..

Don't forget that flashing an International Rom will wipe you internal storage.

That isn't true of custom roms.
The reason why I change CSC files is because some roms prevent you from editting the APN protocol so you can change IP4 to IP6. It's all user preference really and depends on the ROM you're using.

Why is this in our forums
Sent from my SM-N9005 using Tapatalk

For the people that have not been around for a while or have not been following the TMO Note 3 Dev. There is no TMO N900W8 forum.
The Canadian rom (Miscoms) has been posted here since the beginning. Which it makes sense as this is the T-MOBILE NOTE 3 FORUM.
And before somebody says Canada is not T-Mobile its Rogers, note that Rogers and TMO are Identical in bands and radio. Just one says W8 to identify it as a rogers phone. Both will work perfectly on the others networks. (Trust, we have tested this theory out extensively)
With that said.
Thank you very much for the contribution.
For the poster that asked about the bootloader. All of us that work on these roms have bricked a phone or 2 trying to figure out how to force the bootloader. The N900w8 rom, has been out for a while, BUT, you have to have the NA2 bootloader to be able to flash the rom or it will fail, or brick your phone.

Original Dev roms are reserved for people that put out original dev roms. like. AOSP, CM, IOKP, bla bla bla. Stock Roms put out by the OEM and modified go here, not in the Original development section. Modded Stock roms are not "original" developments
Hopefully that makes sense.

without the proper bootloader, that both 900t and 900w8 phones need. you stand to have problems. As with the N9005 roms, they all suggest having the bootloader before you start flashing the roms to insure you do not brick your phone.

I guess I'll be the adult here and say thanks. Always love new additions to the catalog of ROMs. I'm sure all the Canadian users will be happy. Doesn't matter what forum its in. I'm sure if most people read the threads they would know that the Canadian variant is pretty much the same phone.... Please read before you post.... And I don't post much I read read read.....

Sent from my SGH-T999 using XDA Free mobile app

CM doesn't update their updater-scripts when new builds are released. So even though it'd probably work just fine, NC2 isnt included in the asserts and so it refuses to flash.
You'll have to edit the updater-script and add your build to get it to flash. Be aware though, the asserts are there for a reason, and if you are not absolutely 100% certain its safe to flash on your device, you shouldn't edit it to allow the flash.

Just the Updater script? Are u sure
Can u do it for me
Sent from my SGH-T999 using XDA Free mobile app

Yes I am sure. You are getting a status 7 error about the assert right?
I can do it but I cant promise it'll be before late tomorrow.
All you have to do is this:
Open the updater-script with notepad++ (regular text editors will not work).
At the very top you'll see assert lines with different build numbers. There may be two for each build. Replace one (or two if there are two already) with your current firmware build.
Delete the 3 signature files in meta-inf.
Rezip
Flash
If you dont know your firmware build, open terminal emulator and enter this:
getprop ro.bootloader

I will try it, I will let you know thanks

But can u modify the ROM for me because maybe if I do it it I will mess up that so u could do it and upload the rom fixed
Sent from my SGH-T999 using XDA Free mobile app

Id only be uploading the updater-script. Its the only thing that'd be changed. Dont be intimidated by it though. Its a very quick, easy edit. Just replace one or two of the builds in the asserts with your own. If you search xda for updater-script asserts you'll probably find numerous examples.
Just make sure you use Notepad++, and remember to delete those 3 signature files.
Someone else may have already done so btw. Have you searched through the roms thread? CM11 might be more likely to already have it done.

Im going to wait for you to upload the file and I just copy the Updater script to the Zip and where are the signature files?

No idea when a stable version is coming out... I'd imagine soon though, they are on milestone builds. And you know you don't need to download apps everytime right? That's what app backup apps like Titanium Backup are for... And you can also dirty flash too... That allows you to keep your apps installed... Just wipe cache and dalvik after dirty flashing and most of the time you'll be OK. Keep in mind dirty flashing should only be done on the same ROMs with only minor changes...

Yes. Sorry I didnt get back to you yesterday. Got caught up with too many other things and just didn't get around to downloading and editing the script.
But that does look right to me, so you should be good to go. And if you did make some mistake, it'll simply just not flash, so there's not too much to really worry about.
Do you still need help on this?
