Hi all. I have looked around and searched and not been able to find an answer to my question. If a thread has escaped me, I apologize now and please point me in the right direction.
I have a Note 2 T889V formerly from Wind Mobile, now on Virgin (Canada). I bought it off a kid broke it after he flashed the wrong modem on it, so now it runs baseband T889UVBMD1. It's currently running Android 4.1.2
As far as I know, nobody has sucessfully restored a T889V modem after a T889 modem has been flasehed (please! correct me if I'm wrong). Has anyone with this strange combination of modems been able to upgrade to Andoird 4.3? I'd love to be able to.
Your experience would be appreciated.

I am using a Wind Mobile T889v, but here using TMobile. Here is my experience:
In Android 4.1.2, I flashed TMobile/Wind radio/Modem as ease, never got any problem, even TMobile/Wind ROM too, different combinations and all worked as a charm. Eventually I ended up with Wind ROM with TMobile radio since I am here to use TMobile. I used TWRP to flash, and it always worked as expected using the ROM/Modem from MrRobinson:
http://forum.xda-developers.com/showthread.php?t=1975560
And once I even flashed Videotron's ROM/Modem and still no problem.
However, after updating to 4.3, I got big trouble by playing around. First I flashed Wind ROM/Radio without problem and phone worked good using mattlowry's work:
http://forum.xda-developers.com/showthread.php?t=2554226
Then I tried to flash TMobile radio as in 4.1.2. But IMEI corrupted after I flashed TMobile radio TWICE. The first time I flashed a TMobile modem, it actually worked fine. But the second time(supposed to be same radio for 4.3 but from different source) it ruined my T889v. And I had to send it to repair to have it fixed.
Currently, I am running Wind ROM with TMobile modem in my phone, stock 4.3 ROM. And the guy who fixed my phone said there is NO problem if I want to flash Wind modem, which I think yes too.
Thanks. I updated to 4.3 using the Wind ROM, T Mobile modem and devil kernel. Everything good so far. WiFi and LTE working on Virgin.

tried it once without any luck. going back to stock telus ROM at the moment.
has anybody had any success flashing an AT&T modem onto an i747M?
i am using the telus variant
edit: reason i wanted to do this was b/c i was getting some consistent signal drops. after having to go stock telus -> CM10 nightly (8/20), i'll see if i'm still getting any drops. that was the reason i wanted to use an AT&T modem, but if the issue doesn't come back i'll withdraw my inquiry

I'm using 8/18 and I'm not having too many issues. CM has been my daily driver for 2 weeks. I'm on telus as well. I haven't tested LTE, but once I'm back at school I'll figure it out and make sure everythings working smoothly.

CM10 8/20 nightly works great, i'm not getting any of those signal drops i had from before. maybe the phone just needed a full wipe. anyway, i'm not too curious about flashing an AT&T modem anymore. it would be nice to have a choice of modems, but that's definitely the lowest on my list now that there aren't any drops
I am using the LLE8 stock Bell modem even though my firmware is the latest ATT LH1: I did attempt to flash the full LH1 leak including the modem, but lost my IMEI in the process. Seems the modems do not play nice across different carriers, even when the phone is an I747 -- the developers then removed the modem out of the firmware package and the LH1 release installed without any issues. So my experience is that the ROMs are quite compatible, ATT to Canadian users, the source code for the kernel is standard across all SG3 phones according to the developers and the experience of people using kernels irrespective of carrier designation BUT the modem (baseband) does not appear to be cross-carrier friendly. So until a fix is developed and/or one of the Canadian carriers updates their firmware, we are stuck with LLE8 or its equivalent..

yep. i came to the exact same conclusion. i'm not too worried about it; phone takes a few seconds to hop on to LTE where i am, but no big deal
Wondering if this was possible I have been looking at the new JEDI rom however I have tmobile and a ATT branded note 2 (i317) and really looking for the wifi call I onle seen one port and it was this one, but it seems to have quite a bit of trouble still.
http://forum.xda-developers.com/showthread.php?t=2026569
I was wondering if anyone just tried a t889 rom on thier i317 also seen a few people say they have just wanted to hear back from them and how everything works ect.
For instance it was mentioned here I can dont know if anyone has done it though

Yes gsm is the same. Just flash your modem. Correct?

why use a jedi t-mobile rom, if you have the same for at&t.
you need carriers files

It'll work fine. Just make sure you keep you're running an AT&T modem. The ROM itself shouldn't flash another modem, but if it does, just flash back an AT&T modem. I'm also on T-Mobile using an AT&T Note 2. I even flash the bone stock T-Mobile ROM and it ran 100% perfectly out of the box (because I had an AT&T modem on my device). You can enable AWS 3G/4G via a mod here, by the way if you haven't:

This mod sticks across ROMs, but anytime you flash or reflash a modem, you have to redo the mod.
so even if im on a MDB baseband and ive flashed MDL roms but my baseband still says MDB afterwards.. it updated me to MDL? Because ive noticed that after flashing serval MDL roms my baseband does not change. That sounds kinda fishy to me that it wouldnt say MDL. i was thinking that i needed to flash to MDL to insure it will work properly with MDL roms. i was about to odin a MDL root injected rom once i found one to fix this issue but now im skeptical since i think im aready on MDL. Your modem is your baseband? Can i just flash a MDL modem and it will show MDL afterwards not MDB in the about phone. How come it doesn't change when i flash a MDL rom. i rooted and flashed on the a stock MDB baseband and its read the same a dozen roms later. i also rolled back in odin my friends OTA updated MDL to MDB so i could use moto chopper to get root. it rolled back fine. I was able to get root with moto chopper but it still read MDL even afterwards. I was pretty sure it was on MBD even though it didnt say so.

Thanks for the link, but even after flashing the MDL modem in odin it still shows that im on UVUAMDB. is that right? shouldnt it show that im on UVUAMDL now? is it only a s4 problem? i heard on a youtube video that the baseband reads the same but DID update. i've flashed dozens of modems on my s1, s2 and s3 and i knew the modem changed because it say what modem im on. i just want to make sure im using the best modem for my area. i am having an issue with death star 4.0. i use to get a strong lte signal at my home now i barley get 4g and it goes on and off mostly off. lte does work if i drive down the street but most of the time i dont have internet connection at all then it pops up for a couple of minutes at like 4 bars then back to no connection figured it might have been a problem with the modem. other roms i used i havent had any issues with data yet. just test driving this rom because a buddy of mine wants it. i personally prefer aosp roms.

I did the same as you; got the phone with MDB and wasn't on the stock ROM for more than a day or so. It took a few flashes for my baseband to report as MDL once that was out.
I flashed the Root66 KitKat update for Wind Mobile using Odin. As I was looking through the settings I noticed there were no APNs set. I googled for Wind's APN configuration and manually entered them (before I even tested data, perhaps it was working regardless).
So far I've seen a number of mentions warning against flashing the 4.4.2 modem before flashing the 4.4.2 firmware update. However, I've yet to see the modem posted anywhere. The most recent one in the baseband thread was for 4.3. What am I missing?
Normally 4.3 modem will be working for 4.4 too but you should not have older modem then 4.3

It hasn't been posted for that same reason, so nobody will attempt to flash.. Anyone can make a flashable zip for the modem, that it why we are letting people know what happens when you try to flash on older firmware

Ill still post the modems in the near future, but wanted to first get that warning out so as many people as possible already know about it when I do. Flashing the 4 4.2 modem on 4.3 firmware has bricked quite a few devices in the Spirit and AT&T forums already. And despite all our efforts, we have yet to get the debrick method to work
That said, if you have a need for the modem, ill get it for you as soon as I can.
And just fyi, after updating to 4.4.2, you cannot use any older modems. They won't brick the device, but you won't have a working radio/signal.

Heya Doc
I have a Gs3 T999v from Videotron and have been running the 4.3 modem since early this year. I'm currently running CM11 4.4.4.
I was wondering if it would be possible to provide a link for their 4.4.2 modem so I can give it a shot. I know I won't be able to come back from it, but reception with the 4.3 has not been that hot and I've been meaning to get those kinks out. Also since the phone is nearing the end of it's life, at least to me, I don't mind the extra risk. Even if it should technically be entirely safe to do so since i'm running 4.4.2+
Cheers!
I have a friend's M919 that just got modem upgraded to latest 4.4.4 however wifi toggle /the wifi connection does not work.
Is there way to fix this?
If I remember correctly when first Tmobile m919 4.3 upgdate came out there was patch that allowed 4.3 modem to work properlyon MDL bootloader. I ve been searching but I could not find it anymore. I found couple guideson modem so sound is working but the wifi is not.
My poor friend is without a working phone at the moment.
Any help is appreciated.
Thank you all.

You need to upgrade bootloader to current 4.4.4 firmware.
Mismatched bootloader and modem will cause WiFi not to work.

Thanks for your reply.
As far as I know, updating bootloader is a no no for ATT and Verizon variant if you have one of the older MDL boot loaders.
I get mixed responses on Tmobile version. Should I be worroed about anything in particular? As upgrading bootloader on these S4s is like crossing a bridge that you can never come back.

If the model number is M-919 T-MOBILE phone then there is no issue as long as you follow M-919 model thread instructions in op.

HELP!!
I just flashed latest NK2 firmware and the phone has no wifi.
Ah,,, what do I do?
I flashed it several times and it went through ok but wifi toggle does not work. Wifi does not work period. It won't even pick up...
Nobody has ever had wifi problem on M919? Anyone?

And check your info, make sure your bootloader matches the firmware number.
This will give you all the pertinent info on your phone.
