[T-Mobile, Samsung Galaxy SIII] Synthetic.Nightmare:
True.

And although I'm not aware of any immediate benefits of updating, I also don't see the harm if you're already KNOX'd and want to give the latest firmware a try. I moreso posted it in case anyone wanted to pick apart the firmware without having to dl the full update package (including system, cache, et al)
[T-Mobile, Samsung Galaxy SIII] Perseus:
Going Bit OT here.

I wouldn't recommend updating to Knox enabled firmware either. There's a nice discussion on the latest firmware here.

End OT

Yes Spot on and I applaud you for posting! I am picking that firmware apart with the intention of making just a Rom without Bootloader and Recovery. Needless to say without Knox either. I think [MENTION=3760726]saranhai[/MENTION] may beat me to it.
[T-Mobile, Samsung Galaxy SIII] JustZaphod:
Got adventurous thinking this was for the LTE T999L..

Flashed it and in setting it read "No Baseband" so I reflashed the MK4 modem..

I flash the NC2 modem and it mess up my wifi , wifi would not turn on had to flash back to MJC and wifi is working again.
[T-Mobile, Samsung Galaxy SIII] nirogu325:
That's weird. I flashed the whole NC2 firmware, even went back to 4.1.2 with the NC2 modem and bootloader and all is working normally, just as MJC.
[T-Mobile, Samsung Galaxy SIII] pp085ster:
I have the same problem! I even tried flashing the whole firmware and modem package (instead of just the modem) to no avail. Wifi still did not work. Went back to MJC modem while keeping the NC2 bootloader and wifi is working again. Definitely has something to do with the new modem :confused:
[T-Mobile, Samsung Galaxy SIII] nirogu325:
By "whole firmware" I was referring to the ODIN firmware. Are we referring to the same thing?
[T-Mobile, Samsung Galaxy SIII] pp085ster:
Nope! I meant the flashable package including firmware and modem.
[T-Mobile, Samsung Galaxy SIII] nirogu325:
I am always weary of those unofficial methods. Try flashing the full ODIN firmware first. It is what I did since the day the firmware was released and I've no issues at all.
[T-Mobile, Samsung Galaxy SIII] Richcar:
The wifi problem is coming from the kernel we need the new updated kernel for wifi to work I flash the NC2 modem and wifi doesn't turn on I flash the NC2 modem with the AT&T insecure kernel and wifi work perfect so may be we need to flash the NC2 bootloader and kernel for wifi to work
[T-Mobile, Samsung Galaxy SIII] Synthetic.Nightmare:
Interesting. Is this only on tw? Were you running a custom kernel before? I haven't had any problems, but I've been running CM11. Been forever since I've seen the TouchWiz UI on my device.
[T-Mobile, Samsung Galaxy SIII] saotua:
Same here. I have to flash the ATT insecure kernel in order to use wifi. running the S3Rx rom with the lastest bootloader.
[T-Mobile, Samsung Galaxy SIII] pp085ster:
I'm on TW so i wouldn't know if wifi works on AOSP based ROMs. I was running stock kernel (MJC) before. Curious thing is I tried the AT&T insecure kernel too and wifi didn't work for me either on that kernel :confused:
[T-Mobile, Samsung Galaxy SIII] WhoWhere:
I'm running slim with the new NC2 modem and haven't had any Wi-Fi problems.

Guys thats awesome news/issues that you shared...

Who,What,Where,When,Why = [on XDA] is Device,Rom,Kernal,Modem,Mods.

Without the above info it is very hard for anybody to search for "Device 234 fa" if you leave out "Device 234 fa" from the problem list!

Save someone a bricked device by including the Device,Rom,Kernal,Modem,Mods it will also help people searching.

Just my 2 cents :)
[T-Mobile, Samsung Galaxy SIII] pp085ster:
Ok guys so [MENTION=3875215]Synthetic.Nightmare[/MENTION] was kind enough to upload a modded NC2 kernel. So those of you (that included me) that had problems with wifi not turning on on the NC2 modem can flash this to get it to work again :thumbup:

http://xdaforums.com/showpost.php?p=51226677&postcount=12

Oh and SElinux has been set to permissive even though it shows it as enforcing in settings>about :D
[T-Mobile, Samsung Galaxy SIII] kingston73:
I just want to double check before making any changes, the newest Modem can still be flashed as is even if we still have pre-knox firmware? And there is still no real reason to update to the latest full firmware package?

And for the people who said the newest modem broke wifi was that running TW? For people who are on AOSP/CM the new modem works fine?
[T-Mobile, Samsung Galaxy SIII] pp085ster:
Q1: Yes

Q2: That's right

Q3: Yes

Q4: From what I understand, AOSP is not affected

Is that clear? :good:
[T-Mobile, Samsung Galaxy SIII] Perseus:
Just so we put in Perspective, I just now tested the NC2 Modem replacing the MJC Modem I had before. My bootloader has been MD5 from the begining. I am on AOSP Rom (Slimkat ). There are absolutely no trouble with Wireless or Signal.

@pp085ster, I do not mean to belittle or discard your issue. I was just trying to put a working Scenario on the table. For your specific problem, may I suggest you flash a Custom Kernel such as KT747 on either Touchwiz NC2 or Touchwiz MJC Roms ? Do note KT747 is an AOSP kernel that has Touchwiz version as well.

I strongly feel that the Wireless issues are Kernel related and ATT Unlocked kernel is probably not compatible with NC2 Rom. Again the intent is to put perspective for posterity.

[MENTION=3630560]kingston73[/MENTION] does this answer your questions ?
[T-Mobile, Samsung Galaxy SIII] pp085ster:
No worries [MENTION=3639717]Perseus71[/MENTION] :) between [MENTION=3875215]Synthetic.Nightmare[/MENTION] and [MENTION=2972841]enewman17[/MENTION] they got the NC2 kernel on board and flash-ready :D If anyone wants it, its here :highfive:
[T-Mobile, Samsung Galaxy SIII] joeyrivGIN:
Help.. I'm using NC2..in my hometown in Indiana it's GREAT, but I'm on vacation in Wisconsin and the best I can get is G or E. And I've tried EVERY T999 Modem on here. Wondering if there's anything else I can change in the settings?.. Sorry if this is the wrong place to post!
[T-Mobile, Samsung Galaxy SIII] Adreaver:
Check the map for the area in Wisconsin you are in, and try the data speed tweaks in post 2 or 3 of the OP.

[T-Mobile, Samsung Galaxy SIII] sonnykaiboy:
Just flashed to NC2 and everything is working fine including WiFi. I'm on quantum 3.6 ROM
[T-Mobile, Samsung Galaxy SIII] bwb8771:
Would the modem-only flash fix my Bluetooth issue?

Attached is picture of my phone's rev levels. I thought I was fully patched-up (maybe that's my real problem) but now I cannot pair to my BT A2DP speakers - phone doesn't even see 'em.
[T-Mobile, Samsung Galaxy SIII] Perseus:
You could try the UVUMJC modem to see if that makes a difference. I highly doubt that's going to matter. Bluetooth is controlled by NFC implementation in your Rom. So I'd try a different Rom if I am not on stock.

Since you are on stock, I will bet its the Speakers. There's usually a small Caveat that puts them into paring mode. Please refer to their documentation. Usually after they are powered on, there's a couple of minutes of time when they are in paring mode. You just have to be quick enough.
[T-Mobile, Samsung Galaxy SIII] bwb8771:
The phone + speakers combo were working beautifully prior to the 4.3.0016 update, which is why I thought it was ROM/modem related.

If/when I find the culprit and/or fix, I'll be sure to come back here and post my finding.
[T-Mobile, Samsung Galaxy SIII] matrixzone:
Do you plan to release the latest TW kernel also??
[T-Mobile, Samsung Galaxy SIII] bwb8771:
For all of my technological prowess, I'm still a doofus at times. I had to go back and set the A2DP speakers to being "pairable" again - as you suggested above.

No problems with the new firmware - just the old "Chair-Keyboard Interface Error"
[T-Mobile, Samsung Galaxy SIII] Perseus:
Its all good. We all can have that moment every now and then.

So Im Switching back to mjc. I'm getting a ton of random reboots with nc2 installed
[T-Mobile, Samsung Galaxy SIII] chrisram88:
Nc2 dropped me to edge speeds :( . Back to mjc
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
What build is the rest of the system running? Out of curiosity....
[T-Mobile, Samsung Galaxy SIII] chrisram88:
Md5 bootloader with aosp ROM. I tried it and did some test didn't get near 1mbps
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
It may be that it requires the rest of the 4.3 firmware to be installed to function correctly. I've no real way to test this now though.

Anyone else try the NC2 modem with MD5 firmware? Results?
[T-Mobile, Samsung Galaxy SIII] chrisram88:
I was thinking that as well or it could just be my house. Some days is great, some days its spotty.
[T-Mobile, Samsung Galaxy SIII] kingston73:
I've been on md5 firmware since it was first released, I never upgraded my firmware to the knox stuff. I've been getting really good results with the nc2 radio on a couple different 4.4 AOSP roms (AOSB, Resurrection Remix, Quantum). It is giving me consistent 7-9 mb download speeds when I have H+ and even though it doesn't best the md5 modem it seems to keep connections steadier (doesn't jump as much from H to H+). I'm on the east coast in MA if that helps any.
[T-Mobile, Samsung Galaxy SIII] Perseus:
[MENTION=4081205]DocHoliday77[/MENTION], I too have MD5 and the NC2 Modem. Pretty much the same experience as [MENTION=3630560]kingston73[/MENTION]. I too go with AOSP Kitkat Roms. In my case SlimKat. Same speeds too.
[T-Mobile, Samsung Galaxy SIII] BriskT:
Wind Mobile build.prop data tweaks?

It seems that the OP's data tweaks were geared for T-Mobile only. Are there data tweaks that are customized for Wind Mobile?
[T-Mobile, Samsung Galaxy SIII] Perseus:
Yes they are indeed geared for T-Mo. However there are quiet a few among these that do actually work well for other Carriers. Keep the H+ settings aside as they are specific to T-Mo.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Well I guess that answers it, NC2 modem will work on MD5 fw. Those having issues may be in a market which hasn't been upgraded, or it could be any other number of factors. I'd say try it again in a week or so, or on a different rom.

You can still use the info as a starting point to test and find the best values for your area. Those are probably a bit out of date at this point anyway since the rollout of HSPA+42 and LTE here in the states. I'd imagine they'd still be pretty close for the Canadian networks though.

There may be new values for hsxpa and maybe additional lines related to LTE. I can't say for sure right now though as it's been a while since I researched the stuff.
[T-Mobile, Samsung Galaxy SIII] Perseus:
Doc if you don't mind, can you add NC2 Modem to the OP ? I believe its been posted here by @Synthetic.Nightmare
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
OP Updated!!!

Updated OP to include latest T999 modem from build UVUENC2.

This is not the one provided by another member (synthetic.nightmare?). Nothing at all against his work and I appreciate that he provided it for everyone, but the rest of mine are done a little differently and I like to build them the same when possible for ease of support. His is still available if you prefer. Just search this thread for his link. Though done differently, both will flash and provide the exact same results.

I have tested and flashed successfully on my S3.

I will try to build and release the latest modems for the T999V, T999L, and T999N in the next day or so.
[T-Mobile, Samsung Galaxy SIII] Perseus:
Doc it was not my intent to indicate that specific modem to be linked. I just wanted to suggest that the modem be made available in the Op. Hope that makes sense ?
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Yeah, its no big deal at all. I only mentioned it for sake of full disclosure. Id been meaning to get to it, just havent had a lot of time to do much with the old s3! No worries, I took no offense or anything if thats what you were concerned about. I am glad it was made available and to see you were still here helping everyone out while I was awol!
[T-Mobile, Samsung Galaxy SIII] chrisram88:
Going to try the modem later this week like you said Doc and see what's up.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
OP Updated!!!

Updated OP with latest 4.3 modems for the T999L and T999N (UVBNC1), and the Videotron T999V (VLEML2).

Everything here should be all caught up! Finally! Thanks for your patience guys!

[T-Mobile, Samsung Galaxy SIII] SeanFloyd:
Sup guys. I am having an issue. I was on CM11 and used root66_TMO_T999UVUENC2.tar.md5 to go back to stock and am just getting stuck on the Samsung screen. It started to boot up on the "Android is upgrading apps" screen but then went right back to the Samsung screen. The hardware keys start to light up but it just hangs on the Samsung screen. I've tried probably 5 different firmwares (rooted and non) and I have had no luck.

I'd really appreciate any suggestions - thank you.
[T-Mobile, Samsung Galaxy SIII] serio22:
Did you boot into recovery and factory reset?
[T-Mobile, Samsung Galaxy SIII] youtashiro:
Hi! I have a Tmo T999L with the latest baseband NC1 , so I am trying to install the older MB7 baseband , but even as the baseband installs without issue, when the phone turns on I have no signal at all, and no baseband info in the phone , no imei... if I install NC1 baseband again all gets back to normal, am I doing something wrong?? or just those basebands are incompatible ??
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Incompatible. Once updated to 4.3 firmware, the older modems no longer work. Will likely be the same in Kk.
[T-Mobile, Samsung Galaxy SIII] mp3deviant721:
If I'm on a 4.1.2 boot loader I should be able to freely flash newer modems and go back to a 4.1.2 modem without an issue right?

GS³: Carbonized, LeanKernel'd, Philz'd
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Shouldn't be a problem. Download the MD5 modem too though, just in case something doesn't work right. You'll be able to quickly go back.
[T-Mobile, Samsung Galaxy SIII] mp3deviant721:

[T-Mobile, Samsung Galaxy SIII] nirogu325:
Did you do a full Factory Reset after updating? If not, please do.
[T-Mobile, Samsung Galaxy SIII] Ditamae:
Hey guys. Thanks so much for maintaining this thread. I've referenced it time and time again. I have a quick question... I noticed that when flashing a modem in recovery it states that a "backup" is being created just before the radio is flashed. I was just wondering if anybody knows where this backup is written. I can't seem to find it. Perhaps it doesn't exist.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
I did this in the early days as an extra measure of safety. It was never really needed though, especially when we started getting so many others. In the end it was just wasting 60Mb on the sd card so I stopped using it. You probably flashed one where I just commented out that part of the script and forgot about it saying one was made.
[T-Mobile, Samsung Galaxy SIII] Ditamae:
Ah, gotcha. Makes sense. Thanks again.

Im on the 4.4.2 with d2tmo t999v and the network signal is very poor in my home. Which modem should i try?
[T-Mobile, Samsung Galaxy SIII] Perseus:
Check the Coverage Map in the Op. Choose accordingly.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
You can only use the 4.4.2 modem. Nothing else will work, sorry.
[T-Mobile, Samsung Galaxy SIII] londheaakash:
what will happen after flashing modem on my t999l ?

1 ques my mobile giving very weak signal will modem increase it ?
[T-Mobile, Samsung Galaxy SIII] Perseus:
A Modem is the only way the phone communicates with the carrier. So yes, a different modem can have different effect with signal strength. If you are going to flash different modem, make sure it is for your precise device. Otherwise you may loose IMEI.
[T-Mobile, Samsung Galaxy SIII] londheaakash:
thanks for your valuable reply

can i u tell me which modem can i install on my T999L phone m on xperia rom now

and os is 4.1.2

my baseband is bc1 nw can i change it to mk4 or mb7

os matters or not ???
[T-Mobile, Samsung Galaxy SIII] Perseus:
OS does matter to an extent. Please Try MB7 from OP. The other 2 might or might not work given you are on JB 4.1.2

Make sure you have a flashable version of your current Modem in case none of the 3 work for you. If you don't have this, then keep the original 4.1 firmware handy.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
If I remember correctly, if you have updated to 4.3 or beyond, the older modems will not function. You will only be able to use the 4.3 one.

If you are not sure if you have updated your base firmware, open Terminal Emulator and enter this:

getprop ro.bootloader

If it says you are on a 4.3 build, you will probably have to stick to that modem.

so i was asking how to get best battery backup or which rom giving it ???

which kernel should i use ????
[T-Mobile, Samsung Galaxy SIII] Perseus:
That is a Question which should be asked in T-Mobile Galaxy S III Q&A, Help & Troubleshooting

Battery life is a very relative term. The rom does not determine how much battery you will have. Its your usage and the apps you have there will determine your battery life.

It is available for now, but it seems only through Kies OTA or official OTA. This was taken from the T-Mobile Support page.

[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
They get attacked by hackers all the time. Plus they really are always expanding and updating things. Add to that your usual everyday networking issues and there are bound to be occasional issues felt on the user side. It's very rare that something isn't available from any of their mirrors though, and they've been pretty good at solving any problems quickly imo.

I personally love the service they provide us all! where else could I host nearly every full firmware build for all T999 variants, plus roms, modems, and more! All for free! Even paid cloud services usually don't offer what I would need w/o paying crazy monthly fees!

Hi.

I am having intermittent cell phone drops. (My phone sometimes misses calls or can't call out). Would this be modem related?

Should I update my modem to the latest version for my model phone? It is Galaxy S3 on Tmobile.

Thanks.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Could be, but it's unlikely. More likely to be tower/network issues on your area. You can try other modems if you want, but if you have updated to 4.3, only 4.3 modems will work. They will not work on older firmware either.
[T-Mobile, Samsung Galaxy SIII] FlyingPoo:
My Contribution

In case, files disappear, here are the T999 modems only.

[T-Mobile, Samsung Galaxy SIII] gaww:
So if I update my friends S3 to the latest modem (I accidentally KNOX'd it when I ODIN'd the previous firmware - lol), I can flash back to it if it does not work as good as the current one? She is in an area with marginal TMo reception {been that way since Voice Stream days}, so want to see if this would help. It is better on my S4 LTE, but still not great.

A bit off topic but related - I have her on StockMod 4.3 with KT kernel and am thinking about trying S3Rx 3.0 TouchWiz 4.3 NC2, but do not know if it is as stable as the former one. I have seen your posts over there and thought you might have some thoughts. She really gets p----d when I screw up her phone but she likes the new features when they work - lol.
[T-Mobile, Samsung Galaxy SIII] Perseus:
You can consider alternate modems from here. But read Doc's warnings on which ones can go with what firmware.
[T-Mobile, Samsung Galaxy SIII] gaww:
I flashed the latest about 5 minutes after my post.

It is running fine. Cannot tell if any improvement even with using same test servers. There is more variability in re-tests of same modem that there is between them.
