I was happily using 4.4.2 stock on my rooted SGH-i747M, however rooting it tripped the warranty bit, then I had the phone unlocked and changed carriers from Rogers to Bell and because of either of those my device is blacklisted from getting OTA updates.
I decided to try CM and was advised on the CM IRC channel to update the modem firmware first. I updated (or perhaps downgraded?) to I747MUMUEND3 per this thread (http://forum.xda-developers.com/showthread.php?t=1831898) and rebooted but found that I no longer had sound or WIFI and the SIM card wasn't detected. I tried other versions from that same thread with no luck.
I went ahead and flashed CM 12.1 nightly for D2ATT which worked well, however still no sound or SIM. WIFI works but slowly. I also tried 11.2 for D2LTE but got the same result, and flashing 10.1 for D2ATT gave me an assert error. In 12.1 I experimented with other modem firmware versions (I747MVLUEMK5, I747MUMUEND3, I747MVLUEND2) but it made no difference.
I'm not quite sure where to go from here. According to a CM12.1 debug log my boot loader is I747MVLUFNF2. Do I need to match the modem firmware version with this, and if so, where can I get this version? Would flashing stock from sammobile do it, would I lose root while doing so, and how can I get root back? I forget how I rooted it originally but soft bricked it but fixed it with chainfire.
Anything else I can try at this point? I might just be happy back on stock with cellular connectivity.
The latest modem for the i747m is FOB1. The END2 modem is about a year behind the FOB1.
The assert error occurred because d2lte or d2can ROMs are to be flashed to the i747m.
Fixed
I flashed the stock ROM that matched up with my current bootloader version. Inside the stock ROM everything worked as normal. I then installed TWRP and flashed 12.1 and everything worked in there as well.

I am not very much familiar with all intricacies of Android system but i have played around rooting and putting customer firmwares on few devices.
I have AT&T Galaxy S3 with following detals:
Baseband: I747UCUEMJB
Version: 4.3
I had the device rooted in the past but recently un-rooted it and reset the flash counter as well and did factory reset. Did all that since i wanted to use ISIS and couldn't make it work on a rooted S3. Seems it used to work before till they updated ISIS app to patch it.
Now AT&T got 4.4 update and my phone detects it, downloads it but while installing fails at 32%. I have seen many threads where people faced similar issues due to their phones being rooted. Seems something on my phone didn't reset to default.
I found one post which mentions that i can download UCUEMJB_to_UCUFNE4_Firmware_update.zip and load it to phone using TWRP. As i understand, this will update the baseband but android version still remains at 4.3 (?). Is that the path i should be looking for or i am shooting in wrong direction? I want to stay on default firmware since i like to use ISIS till they keep running those cashback promos
Would appreciate some feedback.
Download MJB firmware (thread in General) and flash with Odin. You can stop there or try the ota again.

Thanks for the reply.
Just to confirm so that i don't mess up, i will apply the following(is modem same as firmware?) and then try OTA.
I747UCUEMJB: modem_CWM_I747UCUEMJB.zip
No. The modem is only one part of the firmware. Firmware includes bootloaders, kernel, system, modem and more.

modem T999VVLUFNH2
Hi everybody,
I try to find the updated modem for my S3 (videotron SGH-T999v)
I have the modem T999VVLUFNF1 (ROM LS 3.1 stable KK 4.4.4, KT747 kernel)
When I unzip the official ROM of samsung (older like 4.1.2 and the last samsung update from september 2014) , I only find the file NON-HLOS.bin
According to sammobile the last videotron modem is T999VVLUFNH2, but I cannot find the file. This is the first time I try to update the modem because I have a poor reception in my house.
Thank you for your help
I haven't decided if I will post those or not. Too great a risk with the 4.4.2 modems. If you want to try the latest I can only recommend fully updating as a safe way to do so.
If you really want to be the one to test if it's safe, I'll get it uploaded for you, but understand there is a chance it could hard brick the phone beyond repair.
Reason for all of this is because we know if you flash a 4.4.2 modem on 4.3 it'll permanently brick it. I have no idea if flashing an older or newer 4.4.2 modem on 4.4.2 firmware (like you want to do) will result in the same. Normally, I would guess it wouldn't be the case, but it seems a lot has changed in these new builds that no one understands, and there have already been too many bricks for me to be comfortable trying something new like this without exercising great caution.

Thank you for your reply and your advise.
As I don't have enought money to take the risk, I will keep my actual modem.
Thank again
Don't blame you a bit! But don't forget, you can still fully update and that may help. (From what I've seen, flashing older modems on 4.4.2 doesn't brick, so i think if you updated, it should be ok to flash the NF1 modem if the newer one doesn't help. It might not work, but I don't think it would cause any harm. Just food for thought, but again, I can't guarantee anything with these latest modems...)
If it's a bad signal issue that you did not have before, call your carrier and ask if there are any tower/network/account issues they are aware of.
Your carrier probably doesn't do this, but Tmobile will sometimes give customers a signal booster for home use only. You can buy them online too, but I'm not sure how my h they are these days. (Just make sure it boosts the frequencies used by your carrier if you look into this.)

Just noticed today that my phone is on T999VVLUFNF1 but that there is a newer 4.4.2 release for the T999V phone that is T99VVLUFNH2. Would it be good to update via Odin to this? Is it just a newer modem?
I have a T mobile T999 that is currently flashed with CyanogenMod 11-20141008-SNAPSHOT-M11-d2lte which is kitkat 4.4.4. The baseband version is T999UVDMD5. I have a Lebara sim card in it now, and I'm in France. I'm not getting any signal and I suspect it is because the baseband version mismatch. Is there anything I can do to make this setup work or do I have to downgrade to a different version of CM? Is there and updated modem I can flash on this device or any way to make it work?

Latest baseband is NC2, flash it, and if the device still does not pick up service flash back to MD5 firmware and see if it will pick it up. If not then it might incompatible with your provider..
Thanks!!!! Also Those using T999 switched to ATT
Just wanted to say thank you!!!
Also just wanted to say for those who have a T999 that switched to AT&T this works (I wasn't sure if this would work since it didn't say anything about AT&T working with it. To be perfectly honest I didn't read everything but again THANKS!!!!!!
Hi Guys,
I got the OTA update ( T999UVUENC2 ) about a month back and since then, my Wifi has stopped working. It stays greyed out when I try to turn it on. Just won't turn on.
The logcat says that the "WiFi driver is unstable".
What I have tried so far (with no success):
1) Flash the same build again (T999UVUENC2).
2) Flash the root666_T999UVUENC2 build. (Currently, I am on this)
3) Flash Cyanogenmod 11.
4) Factory reset.
5) Pull the battery out when the phone is on and put it back again.
6) Modify/delete the wpa_supplicant.conf file.
Can someone please give any directions on how the "Wifi driver can be fixed"? I understand from going through the forums that downgrading from 4.3 to 4.2 can cause a brick. However, can I downgrade to the previous T-Mobile 4.3 build (T999UVUEMJC ) without causing a brick? Do you guys think that can help fix the Wifi?
Any help would be greatly appreciated.
Could you point me to what one exactly i need for T999LUVUBNF4
SGH-T999L Will Not Mount Ext Sd/No root or load file from .zip to root
I always get stuck at the boot screen where I am supposed to Update from Zip, but my phone NEVER lets me Mount the External SD card, I have a 64GB card, failed, 16 GB card, failed, what am I missing. All the good tutorials, ESPECIALLY yours, get me to that point but being unable to load that .zip file from sd just murders me. The Phone is on 4.3 and I believe I loaded your stock 4.3 firmware after failing to get this part done and then trying every single rom possible (didn't realize this had murdered me) until I managed to get back to this stock rom. Why does it not want to load from ext sd? Is it the file system? I've never had any issues with any of these sd cards, and they aren't generic cards, one is a samsung other a sandisk,

I bought a LTE Samsung 10.1 P605 from Verizon some months ago. It came with 4.3 already on it factory. I have been able to root it but that is all. I would love to get to a custom rom but with the Verizon boot loader issue not sure if totally possible get around the lock with 4.3.
I have read P605XXUCNE2 has been made available for the P605 LTE 10.1 models but my device does not show from it for update. I have gone to Sammobile and downloaded the P605XXUCNE2 (Nomadic) download listed for it.
Issue:
- Kies does not show for an update nor I see no way to push this rom NE2 manually
- Odin fails each time I try to push P605XXUCNE2 I assume due to boot loader
- Odin will not let me install TWRP (openrecovery-twrp-2.7.0.1-lt03ltexx.img) posted for the LTE model
So I cannot install a OEM firmware like NE2... How can I force or push a firmware to this darn device if ODIN fails? Am I locked in no mans land since I pushed a model that has 4.3 already on it? Am I stuck since it is a Verizon LTE model...?
Anyone can provide any steps who know a little about this model how I can get NE2 on it or TWRP even though OBIN says fails each time I try??
Model came as 4.3 with firmware P605VVRUCNC2
I'd guess the issue is that your device is not an SM-P605. Your device is an SM-P605V. The latest firmware SamMobile is showing for the 605V is NC2 (which should be 4.4.2, not 4.3).

Thx...I read it work...
With this info is there a way to get TWRP to install on the 605V?
I am pretty sure you are screwed if you want to flash Roms. Probably best bet is to sell it pay off what ever you owe or break contract and go to T-Mobile or buy WiFi (better for flashing Roms if you can handle not having LTE)
Hey guys. I just got a galaxy s3 from virgin mobile SPH-L710 last week and I managed to install cyanogenmod 11 m10 on it. But to go to cm11 m11 asI've recently learned needs the latest bootloader and baseband.
I know there's two threads in the development section on how to get the latest stock nd8 update.
One had a link to download and open in Odin however the link doesn't seem to be good anymore.
The second thread is for the Odin one click full restore but when I run it it fails on aboot.nbm. I've tried using different USB cables too but it doesn't seem to do any good. Any ideads on how else to upgrade?
I can assure you this is false. I have a Virgin Mobile SPH-L710 on baseband MK5 and I am running a nightly build that is newer than M11 and have no issues.
You should be fine with a dirty flash over M10. Just wipe the cache before flashing.
OK that's intriguing. How did you get MK5 baseband? I just got my s3 last week and its on NF4 which I have no idea where that is in relation to any of the others i've seen around.
I've used the cm updator in settings to try one of the m11 nightlys earlier last week but I had no service so I restored a recovery of m10. Would performing a dirty flash of a nightly build be any different?

My phone came with MK5 on it, when the phones were shipping with 4.3 installed.
To be honest with you, I would disregard the modem/baseband concerns altogether if I were you. These phones do come with KNOX on them and flashing bootloaders and modems is seriously a huge risk. Flashing a bootloader older than the one you are currently on will trip the killswitch and you will have an irreparable hard brick.
The only time I could possibly think considerations with the bootloader would need to be made is if you were looking to flash a rooted stock TouchWIZ ROM that needed newer bootloaders/modems. But, I really can't speak to that, as I am trying to avoid TouchWIZ and am only familiar with AOSP ROMs.
You may need to flash an APN fix in addition to the ROM and GAPPs. I also use @decimalman's custom kernel, the DKP kernel and have no issues. Basically, when I am clean flashing nightlies the order goes like this:
In PhilZ Recovery found here: https://goo.im/devs/philz_touch/CWM_Advanced_Edition/d2lte/
ROM
GAPPs
Kernel
APN fix
Re-Root system for SuperSU
Reboot
I sent you the link for the APN fix, available in another active VM S3 forum, in your inbox. Download and flash the zip and that should fix any service-related issues you're having.
OK I did a clean flash of the latest nightly, flashed the apn fix then booted. Still no service. No apn are on the device nor is it able to save any I manually put in. And settings shows the baseband version as unknown as well as anything else that has to do with cell service.

And, you tried flashing all of those with the lateat version of PhilZ recovery?
Yes. I tried it with the latest version of philz and flashed all the zips you had listed in order but still the same old issues. However I noticed that WiFi still works. I can also go back to M10 and have no service issues. The other thing im noticing is that CyanogenMod thinks this is a SPH-L710 but apperently its really a SPH-L710T. The difference being that my phone has a tri-band radio for something to do with Sprints Spark.

When you're on M11, have you checked in system root --> /etc folder to see if the apns-conf.xml is there? You might tru copying that over from the M10 build.
In the meantime, I'll look into the modem a bit more. The CM forum users all seemed to agree on that as a fix.
I'm getting error status 7 when trying to install gapps on my Rogers sgh-i747m. Here is the file I'm using gapps-lp-20141212-signed.
I'm trying to get CM 12.1 running smoothly on this device if thats even possible. So far all I've been able to do is get 12.1 running no wifi, receive messages but can't send them. If there a version of CM 12.1 specifically made for the Canadian version of this phone? Right now I'm running the sprint version, it wouldn't let me install att version, saying my phone was d2spr.
Any help would be greatly appreciated.
What bootloader and modem are on the phone? Are you using the latest release of twrp?
Your phone is identified as an i747m in download mode?

Gapps installs fine using TWRP but I've still got no WIFI using Canadian version of Galasy s3. I've tried installing a few att, verizon and tmobile versions, all give me network connection but no wifi. Wifi works fine using stock rom.
Which bootloader and modem are on the phone?
The wifi is working now. Not sure why but it seems to take a bit for the wifi to kick in after the software has been loaded. I'd say it took about 30 minutes. I experience the same issue if I let the battery die. It always comes on though so I'm happy with the way CM 12.1 is running on my S3.
What bootloader and modem are on the phone? Wifi should turn on immediately with all ROMs IMHO.
