Looking for a wind 4.3 modem

I have a wind t889v, I am stuck on stock after taking a 4.3 OTA update, i rooted and flashed the 4.1.1 modem from here http://forum.xda-developers.com/showthread.php?t=2061031 so that i could unlock my phone, but now I am stuck with this old modem since there is no link there for the 4.3 version. Does anyone have a link to the wind t889v 4.3 modem?
EDIT: I am going to try flashing a stock 4.3 wind rom for now, but how can i upload files to my phone? I have installed kies and kies3 but neither seem to detect it, and windows explorer does not show my phones storage. I have had to transfer files through my mega cloud folder in order to get them on my phone, but that is going to be a pain in the ass for a 907mb rom...
And my next question: How do I know what roms are flashable for the t889v after taking that stupid 4.3 update? I found this guide but its for a verizon note 2. I am rooted and I am hoping there is some customized odin flashable firmware for me

all roms are flashable while on the 4.3 bootloader. you will need to install a custom recovery (CWM, TWRP, etc). here is a link to the modem: http://forum.xda-developers.com/showthread.php?t=2554226 you can flash this in said recovery

Oh alright, I suppose I can give it a shot. But I have been told its not possible to flash anything other than stock factory 4.3, for example here:
Baenwort said:
If your phone has factory 4.3 you can not downgrade to a lower version as the KNOX functionality that is built into the 4.3 bootloader will prevent the flashing of a prior version.
You can still root with stock factory 4.3 but you'll need to either trip the KNOX counter or use one of the more involved methods. Is there a reason you are trying to flash such an early version?

I have already rooted with saferoot, can i just flash the recovery and then custom images as normal?

what that is referring to is the bootloader. which currently can not be downgraded. install a custom recovery and you can flash rom zips not images. most roms do not have a bootloader in the zip so there will be no conflict

thanks you were right, i used the unified android toolkit to install twrp and it worked. so can i just flash any rom for the t889? because i believe i read that only touchwiz roms work. if thats true i havent seen many roms that i can use.

N7105, i317, and SGH-T889 ROMs are usually OK. Don't flash another device's modem. There is a whole mess of ROM options out there.
Make certain your APN is correct in other carrier designated ROMs. Don't flash recovery from automated recovery installers as they will not put the correct version in unless you are on a ROM with the correct build prop settings for the SGH-T889 (if your using a Tmo US device).

So I flashed DN3, it was for n7105, its an AROMA installer. I jsut realized that thats what you meant when you said dont flash automated installers. It required that i flash an n7105 modem to complete the installation. Can i fix my build.prop after? How do i flash this rom without using AROMA? aaah
EDIT: I am going to try to flash the wind 4.1.1 t889v over top of this using mobile odin since my modem doesnt work now.

I was more referring to ROM Manager and Goo Manager. ROMs that flash modems are atypical. Usually they leave you with a choice to install one of a couple choices or leave it as is. Sometimes they don't.
You may be able to find the 4.3 modem appropriate to your device around here somewhere. That will work much better than the 4.1.1 if you can get it to stick.

I flashed the wind 4.1.1 modem with mobile odin but i still have a "no network" icon. ill try to find a 4.3 wind modem and flash that. hopefully i havent bricked my modem, i thought this rom would be cross compatible. damn...
EDIT: I used mattlowry's 4.3 wind modem above, but still "no network" icon (the one that looks like a no smoking sign. not really sure what to do now. i was told this rom would work but i guess not. hopefully if i flash back to a t889v firmware i can get my modem working again....
any advice?

You could mobile Odin the stock image from sammobile or the root66 to flash everything but the bootloader. Kies recovery could maybe work. T889V is stubborn with modems IIRC. Teshx had problems with this very problem quite sometime ago IIRC.
This fits in my "this is a problem" category, backup and save your data.

yeah i did some wiping in recovery and managed to soft brick my phone, then using pc odin to flahs a stock image got my phone back to life and showed signal bars again, then i flashed the custom recovery back on. so at least i know i can save my modem when i do this again. i then tried replacing the modem.bin files in the dn3 istall zip with t889v modem.bin files, tried reflashing it with the new modem.bins but it still gives me the no network symbol instead of signal bars.

Sgh-i747 4.4.2

Hello all. I just received a galaxy s3 from my sister in law running 4.4.2. I am aware I can't downgrade the complete firmware using Odin. The phone it's rooted. My question is what can I do with this thing as far as playing with roms and what not? Can I only install 4.4.2 based roms? Can I even unroot? I have been rooting and installing roms for years now but never have a phone felt more unfriendly before this. Thanks in advance.

Is the phone running stock 4.4.2?
You can install a custom recovery to the phone, copy some custom ROMs to an external SD card, and try out a bunch of ROMs.

Yeah its stock 4.4.2 rooted with clockwork mod recovery. Do the roms have to be 4.4 or 4.4.2 based? Tried cyanogenmod 4.3 and failed. I pretty much would like to flash via odin to go back to stock unrooted but 4.4.2 was over the air. Got 4.3 via sammobile but that fails. Kies won't show my device for firmware recovery. Shows it as normal to sync.

What error did you get when trying to flash CM10.2? Is your CWM up to date?
I would have assumed that CM10.2 would be comaptible with your KK bootloader and modem.
Do not make anymore attempts to flash 4.3 via Odin. This could result in a bricked phone because a KK modem on a 4.3 bootloader cannot be fixed using any method available on XDA.

Yeah I'm aware of the boot loader and modem downgrade issue. Tried odin once and just left it as is.

Is your CWM up to date? What error did you get when trying to flash CM10.2?

I don't remember the error. According to Rom manager, my recovery is up to date

What version is the cwm? I prefer to manually flash a custom recovery instead of relying on ROM manager.

Cwm 6.0.4.7. I've always used rom manager except for my galaxy nexus. Flashed with windows terminal and fastboot.

Since CWM is up to date, try flashing the most recent CM11.

Older cm roms, and any older roms should run fine on NE4. Some may not flash though, such as cm10. This is because the updater script doesn't include NE4 as it wasn't out when the rom was built. If you edit the script to make it flash, any of the available roms should run just fine.
As it stands though, the easiest thing would be to do as audit13 suggested and flash cm11. That and most other recent roms should flash just fine w/o any extra work.

well, after downloading the most recent cm11 nightly and gapps, rebooted into recovery and wiped. when trying to flash cm11, sd card not mounting. couldn't mount, restored a backup only to be greeted to a display that would not go to sleep and a fury of app and processes stopping pop ups. settings-accounts-backup and reset-factory data reset-etc did nothing but ask for a password. did it through recovery to a perfectly working phone with baseband version: unknown, IMEI: unknown, IMEISV: unknown. flashed the NE4 modem Doc posted in another forum, no dice. same message from cm as before. this time i remember. it was a bunch of basebands not including NE4.

And getprop ro.bootloader says NE4. first said unknown but maybe i typed it wrong.

Got it all back running. tried the S3Rx NE4 aroma zip that would end with installation aborted. found enewman17's post on updating using a stock-rooted 4.4.2 zip after flashing Doc's modem zip. all is well! So thank you DocHoliday77, and thank you enewman17!

Glad you got it working!

[Q] No carrier/SIM support after 4.3 stock restore

My ATT SGH-i747 was rooted and running 4.4.2 until an OTA this past weekend soft-bricked the phone. Phone would boot to a blank screen but still allowed access to download and recovery modes, thankfully.
With help from this awesome forum, and a stock 4.3 flash via ODIN, thanks to enewman17's epic efforts and thread , the phone is back, but now won't recognize the SIM - and baseband version is "unknown" - I suspect I need to now go up to 4.4.2 to get the hw recognized by the sw. Went to ATT and they put a new SIM in but to no avail
CWM recovery is gone, but I can reload that easily enough...
Do I need to just flash the modem, or is the bootloader involved too?
Is there a single flash or .zip that will get the ROM (incl CSC and Modem) up to 4.4.2 in one shot?
I never really wanted to go this deep but here I am so now I'm looking for advice or direction as there are so many directions to look... thanks in advance!

Mismatch in firmware
Digging deeper, using Phone Info *Samsung*, I have noted the following
bootloader version: I747UCUFNJ1
baseband version: <blank>
pda version: I747UCUEMJB
csc version: I747ATTEMJB
skip a bit...
modem version: <blank>
hardware revision: <blank>
mobile operator name: <blank>
mobile network code: <blank>
So it would seem I have a mis-match of versions, where it seems all should be the same..
Would it be safe to flash to MJB following this thread?

Your modem (baseband) appears to have been compromised in the process of downgrading from Kitkat. You could try either of the following solutions...
1) Flash the UCUEMJB modem via custom recovery to return you to complete stock 4.3. You can see the modem file here ....
https://www.androidfilehost.com/?fid=23269279319197285
2) Do a complete stock restore to 4.4.2. You can find the stock update zip via the following thread ...
http://forum.xda-developers.com/galaxy-s3-att/general/ucuemjb-to-ucufne4-firmware-update-t2808654
If you can reflash the 4.3MJB modem, you can check to see if you can get an OTA update to 4.4.2. Using Option 2 requires you to be on complete stock 4.3 so this may not work if you currently don't have the baseband/modem. I would strongly advise you stick to the custom recovery flashable files for now and avoid Odin. You would, however, need to restore custom recovery via Odin.
Hope this works for you.

Thanks for the detailed reply with links, Larry :good:
So I guess my plan of actions will be
1) re-install custom recovery w CWM to my external SD card as was previous
-do I *need* later version of CWM? Previous one of mine was 6.0.2.3, IIRC, that is what I can easily flash back to the phone
2) install .zip (from https://www.androidfilehost.com/?fid=23269279319197285) via CWM
If that doesn't work, I was interested in the S3Rx ROM vs. a stock 4.4.2 ROM - is there any way to go straight to a custom 4.4.2 ROM or should I get the modem working in 4.3 first?
Lastly, Where can I find a later version of a CW Recovery Touch .tar to flash via ODIN? (third stoopid noob question in this post, I know...)

You aren't the first to have this issue. This is why I am still on NE4 and did not take the OTA to NJ1. The update is pointless anyway, all it does is patch the kernel so towelroot won't work anymore aside from updating the bootloader.
Since your bootloader is NJ1, that is your firmware which cannot be downgraded. If you try, you will brick. You have to work with NJ1 files here only. Sure you can flash older modems, but stick to NJ1. I suggest using ODIN to flash a custom recovery, then use enewman17's NJ1 .zip file in said recovery to reflash all the NJ1 stuff. Then do a complete factory reset. You might need to flash stock recovery to do the hard factory data reset, as I am not sure if it can be done in CWM or TWRP.
In the future, I suggest freezing the update and not upgrading until people on here do it and report how it's working or rather not working in this case.

Still can't connect properly to the network

It's been another few months and still the same problems with all ROMS i try, when the screen is off i lose connection to the mobile network, When i turn the screen back on it will connect and start buzzing and alerting me to every unread message and e-mail Which gets annoying very quickly let alone missing messages and calls.
This happens on CM 12, Pac man rom, GPE and others. Both with 4.4.4 and 5.0. CM 11 works fine for me without this issue.
I see people say they are using these roms without this issue so something is definitely wrong but I can figure out what.

Baseband M919UVUAMDL

You may need to update the baseband a bootloader in order for the phone to work properly with the latest ROMs.

Thanks for the reply, before i screw anything up there doesn't appear to be any explicit guides. I'm assuming i use this guide http://forum.xda-developers.com/showthread.php?t=2678774 with the OK3 Rom. beyond this is there anything i should know, like will i have to unlock and root my phone again, or anything like that?

The stock ROMs for the sgh-m919 are here: http://www.sammobile.com/firmwares/database/SGH-M919/
The simplest way to update to the latest bootloader and modem would be to flash the phone back to stock using the above-linked software.
Once you are on the latest stock ROM, flash the latest TWRP to the phone. Once TWRP has been installed, you can flash a custom ROM. Rooting first is not necessary if you intend to run a custom ROM.

Sorry for the late update but I got it working thank you.
The FOK3 and FOH3 didn't work for me, once installed it still showed the MDL version. Once i did the FNK2 it worked.
Is there a reason to upgrade to the FOH3 or FOK3 from the FNK2 versions provided i can get them to work?

I always recommend running the latest bootloader and rom but, if the bootloader and modem work without issue, you can hold off.

I747 doesnt reconigze the sim card after install custom rom

good afternoon, I have a Galaxy S3 SGH-I747 Model using ClockworkMod install the [ROM] [4.4.4] SlimKat d2att (at & t) Stable 9.0 and [Gapps] [4.4.x] Official Slim GApps TRDS (Slimkat) and now not recognize me the sim card. i bought this phone in amazon for use it here in Madrid. i dont know if is a Modem issue. I appreciate all the help you can give me. Thank you. (sorry for my english)

Does your sim card have a pin code that you enter each time you boot the phone? If yes, does the phone ask for the pin before unlocking the sim? What bootloader and modem are currently on the phone? Did the phone work before installing a custom ROM?

@audit13 , mine said "no service available" after moving from KK to lolli and i flashed a "write to extsdcard fix zip" and it fixed the issue , i.e. can now make and recieve calls. dont know if is same issue (or why exactly that fixed mine) but i have a KK "write to extsdcard fix.zip" if you think it would help.

@mrrocketdog, I've never heard about that zip until your helpful post. I must keep that in mind for the future even though I haven't had an s3 for quite a while.

The problem is the bootloader and modem. They need to be updated to work with the latest ROMs.
If the phone is sim unlocked, I recommend flashing back a stock rom using Odin and the firmware from sammobile, set up the phone, run ota updates until the phone is running the latest bootloader and modem. This is tedious and takes the most time but it is the safest method in my opinion.
If you don't want to go this route, just flash the latest modem and bootloader using twrp, flash the custom rom, flash gapps.

@Budare , here is the thread to upgrade bootloaders and modem if you decide on this route rather than flashing back to stock and running ota updates as @audit13 suggested , which IS the safest route. (always always always a certain % of risk ; no matter how small , to flash anything. not trying to scare you , just being honest)

The problem is the bootloader and modem. They need to be updated to work with the latest ROMs.
If the phone is sim unlocked, I recommend flashing back a stock rom using Odin and the firmware from sammobile, set up the phone, run ota updates until the phone is running the latest bootloader and modem. This is tedious and takes the most time but it is the safest method in my opinion.
If you don't want to go this route, just flash the latest modem and bootloader using twrp, flash the custom rom, flash gapps.

thank you audit13, but how i run ota updates??

To run ota updates, you need to use Odin to flash the stock att 4.1.1 rom using Odin. After setting up the phone, check for software update under the phone settings.

i dont know if is because im in Madrid, but the phone doesnt get updates, thats why i want to use another rom. what can i do?

Not sure but I have received OTA updates even when the phone is not in the phone's original country. The OTA updates came over wifi.
If you want to use another ROM, you can install TWRP, boot into TWRP, flash bootloader, flash modem, flash custom ROM, flash gapps. If flashing the modem bootloader in TWRP, DO NOT reboot the phone in between flashing this files and make sure the bootloader and modem version are made for each other.
