This is probably not relevant to the modem, so Mods can delete this if I piss them off, but i have solved my own WiFi speed problem and want the world to know:

I am not sure if this helps you all as well. I have been getting only 3 to 4Mbit/s down (I have a 40Mbit/s at home) on both phones and played around in the wifi settings.

In the advanced WiFi settings of my i9300 and my t999, I changed the WiFi frequency band from Auto to 5GHz only and voila, now instead of 3 to 4Mbit/s i get 35 to 39Mbit/s down and 5Mbit/s up.

I hope this helps a couple of people out (say thanks if it helps you so I can see if this is a bug).

No more buffering and waiting for stuff to load.

I can only imagine that it tried to use the b/g band instead of n, which is faster - or maybe was toggling back and forth preventing it to go full (retard) speed.

Again, I hope this helps.

CM10.1 running latest nightly on both t999 and i9300, same result. works like a charm now.
[T-Mobile, Samsung Galaxy SIII] rpgdev:
I wonder, can I make the phone connect to a 3g frequency that it isn't intended to by changing the modem? For example, this phone doesn't connect to HSDPA 900mhz frequency, can I enable this frequency by changing the modem? At first glance I say that that's not possible, but I don't get all the talk about modem files (why do you really need to be messing with that?) and that reason would provide an incentive to do so.
[T-Mobile, Samsung Galaxy SIII] niphoet:
Flashing a modem from a different device (even for the same device from a different carrier) is almost always a recipe for a brick. The only exception I know of is that, I believe, some people were able to flash a Verizon modem to the Virgin Mobile (Sprint) Optimus V. Either way, you don't want to risk your phone.
[T-Mobile, Samsung Galaxy SIII] rpgdev:
Just as I thought. Thank you.

To strengthen edge

At home my signal is fine but at work I am maybe one bar and edge. Is there anything that I can do to boost the edge signal or at least get a more consistent edge signal? At this point I am not even worried about 4G at work; I just cannot imagine that happening. I have tried every radio and I get from G to E with one or two bars on most of them. Never 3G or 4G or H.

Any suggestions appreciated…..thanks
[T-Mobile, Samsung Galaxy SIII] Protricity:
I couldn't get 4G to work with anything but the Official Modem Release.

If you lost 4G, try that release. My guess is the 4G is broken on so many roms because they're using the newer modems.

I'm running jdeloach's ParanoidAndroid AOSPA 3.15 port with LJ4 and i can't seem to get any solid hspa+ connection. I'll bounce from umts:3 to hspa+ for a second then jump right back. At least i believe that is the right terms. I have tried both LI8 and LJA with similar results. Is there something i'm missing? Also, @ami2510 i did set mine to 2.4 and now i actually get wifi speeds as well, thanks for the tip.

Re: [Baseband] ALL T999(V) Modems! w/ MAP and Data Tweaks! Nov 14, 2012

Your welcome, man. Glad it helped! It's really odd that that worked in the first place!

I'm running li8 and get HSDPA+ from time to time but it really depends where you are in Seattle, where I'm at.
[T-Mobile, Samsung Galaxy SIII] adrake400:
Quick question, I went on a business trip a few weeks ago to Chicago from Charlotte, when I left Charlotte I had 4G no problem. I land in Chicago and the entire trip I was stuck on edge and even upon coming to charlotte I am still on edge.

I have tried both the LI8 and LJA modem and still stuck on edge.

Any ideas to help?

Flashing different kernels won't fix data issues.

Check your IMEI.

latest radio

Where do I find the latest T-Mobile radio?
[T-Mobile, Samsung Galaxy SIII] Perseus:
A Radio is a hardware piece inside your phone. I take it you are referring to Modems or CSC or Baseband. You need to specify your Device bro.

Anyway if its SGH-T999 (from your Sig.), You go here for UDVLJC Modem.
[T-Mobile, Samsung Galaxy SIII] pottyvick:
Really odd... Flashed the Lj4 modem on my tmobile gs3. Now my data speed doesnt change to hspa+ at all, just stays at 3g but the speeds seem faster. When i switch it to edge only it displays the old G netword only... Im so confused lol.... ill flash a different radio to verify

Update: Flashed the Li8 modem and its back to h+...Speeds are much better with this radio. And I Am in Central Phoenix Arizona...
[T-Mobile, Samsung Galaxy SIII] gyggyty:
Yeah the code is *#*#4636#*#*. Or just *#4636#* for ics. U can change the radio frequency with that command on ics but not on jellybean. Does any1 kno a way to do it for jb?

[T-Mobile, Samsung Galaxy SIII] jele:
After flashing these basebands now my googleplay doesn't work says "no internet connection" tried removing cache all that crap I tried adding a new Google account and it says cannot establish a connection with Google's servers, also Gmail won't sync either -- tried uninstalling play updates tried reflashing gapps - still nothing same problem - anyone else? Or any suggestions how I can fix this without wiping whole device ?
[T-Mobile, Samsung Galaxy SIII] Perseus:
Before you try all these apps, have you tried to see if you have basic Internet connectivity ?

Also do note this is a SGH-T999V thread. That's a Canadian variant of the US version Galaxy SIII (SGH-T999). Your device from the signature is American version. So as said in the Op, these modems are not meant for your device.
[T-Mobile, Samsung Galaxy SIII] PostMeridianLyf:
These modems work fine on my US t999.
[T-Mobile, Samsung Galaxy SIII] gyggyty:
No its both T999 and T999V. The canadian variant is clearly labeled from the US variant.
[T-Mobile, Samsung Galaxy SIII] nmyron:
I was about to say... According to the OP, this is the TMobile Galaxy S3 Modem store, and the TMobile S3 is the T999. Not the T999V. The V is the Canadian variant (if I'm not mistaken), however these radios work on it as well (also if I'm not mistaken)
[T-Mobile, Samsung Galaxy SIII] DigitalUnderground:
OP title says t999 (v) just sayin
[T-Mobile, Samsung Galaxy SIII] nmyron:
Because, I believe, its shorter than typing T999 and T999V. Kinda like people writing about an unknown person would write (s)he instead of he or she.

I was going to ask also. It does say ALL in the title and I bookmarked this as the be all end all location....
[T-Mobile, Samsung Galaxy SIII] Perseus:
You mean other posts in this thread. Doc has not updated the OP in a while. Although In an ideal world it would have been nice to have OP list UVDLJC modem too, others have posted the link to that modem anyway.

As to the T999 vs. T999v debate, I did think this to be T999v only. But now I stand corrected. Thanks a lot.
[T-Mobile, Samsung Galaxy SIII] stonew5082:
Well I agree the thread should not be sticky if it's not updated at least every few months. Or a current user could take ownership at least. Makes sense. Stickied posts should be accurate and up to date. I'm not complaining just commenting.

So Sorry to Everyone!

Hey guys!

I am so sorry for just disappearing like I did. I don't have a lot of time at the moment, so I won't get into any deep explanation right now. I just wanted to drop in real quick to let folks know I will try to get my threads updated within the next week. (hopefully this weekend). I do have an awful lot going on right now, so I may not be online to the extent that I was previously, but hopefully that will just be a temporary situation. I have a new computer and will do my best to keep up and help out like I did before.

I offer my deepest apologies to everyone for abandoning for so long, and to those who have been concerned about what happened to me, I am very sorry for not getting in touch sooner. (No, I didn't die, get arrested, or go to rehab!) Nothing quite so bad as that. More of a "Murphy exerting dominance over life" type of thing!

Anyhow, I have to go for now, but I am back and will talk to you guys more soon!

Maybe I don't understand how to use the map check thing in the OP... I'm in Dallas TX - and I don't seem to find any information about which modems work better in this area. So far I've been on JLA - JLC - LI8 - LI7 and LI6 and I don't think I'm seeing any significant difference between any of them honestly. Here in my area at least................

Anyone in the DFW area seeing any differences between any of these? or can somebody better explain A) how to use the map check feature, or B.) what are the differences between these?

I don't seem to see any difference in signal, speed, gps or even battery honestly. All seems the same basically...?
[T-Mobile, Samsung Galaxy SIII] sparkie6point0:
Hey there everyone! I followed Doc's instructions TO THE LETTER for the +42 mods. Not only did the internal modem go faster, the phone as a whole got faster too! Hey Doc - I can get back to you in a couple of days about any changes in battery consumption because of the mods. Before the changes, my battery would run for about 15-16 hours (100% down to zero) before I had to recharge. I also have Greenify on my phone to help curb unwanted background battery consumption.

Thanks again for the tweaks!!!

Yu may have to search first that phone i think if anyone can confirm this is not support it only the ones in the thread. Tried google it first the phone..
[T-Mobile, Samsung Galaxy SIII] mryounghc:
Most likely your imei is gone. Go to "about device" then "status" look for imei and there should be 15 numbers. If its a "0" then you lost it.Happened to me too and had to go the process yesterday. Do a search here for imei repai or lost imei.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Do check your imei. I doubt its the modem unless you flashed a different one or it wasnt working before. Flashing cm roms shouldn't affect the modem at all.

How to downgrade/upgrade the baseband version?

Any help would be much appreciated.
[T-Mobile, Samsung Galaxy SIII] Sixonefour:
Just download the modem you want to use and flash it like you would anything else in recovery. Reboot, done.

Make sure you're using your carriers modems though (T-Mobile, ATT, Sprint, etc).

The modems are in the OP. You can also have a look at the map to see if anyone posted any results for various modems in your area.

You can find the DMD5 modem here: http://xdaforums.com/showthread.php?t=2276670

[T-Mobile, Samsung Galaxy SIII] Misterjunky:
Just a suggestion.

I just wanted to make a suggestion about adding support for the 100% STOCK MODEMS and KERNELS for the T999

and T999V devices in this thread.

Since it's kind of difficult to find the 100% STOCK cwm/twrp flashable kernels and 100% STOCK ODIN flash kernels

it really would be very helpful if you would support these in this thread.

Thanks!
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Not sure what you mean by 100% stock modems, as the modems I have posted are just that.

As for the kernels, I was going to do this a while back, but I'm pretty sure someone else got to it first. Ill try to find the thread. I may still go ahead though just to make everything easy to find in the stickies.

Was going to try to do the same for all stock and custom recoveries too.

Ill try to figure a good way to add it all soon.

And btw, the other day you asked about the .md5 extension on Odin files. You can remove it so it is a simple .tar file and it will flash just fine.

Be aware though that without this check, it will not detect if its a corrupt or useable file.

Just swapping out the modem or removing it should be ok. But I haven't done that myself, just so you know.
[T-Mobile, Samsung Galaxy SIII] Misterjunky:
re: stock kernels

Thanks, I will be looking forward to seeing 100% stock kernels here soon then.

I have done so many searches here in xda as well as google and to be honest, so

far I have never found a 100% stock current kernel for the T999 T-Mobile phones.

Same holds true for the AT&T phones.

Many people here on xda after trying a lot of the custom kernels want to return to

the stock kernel without having to reflash their entire roms.

I know about Mobile Odin but not many people here have it installed, it's a paid app.

Thanks,

Hey guys,

I'm a newb when it comes to modems so I apologize in advance for these questions. I did some searching on xda and came up short or just didn't know where to look, so again, I apologize. I'll try and make this concise and organized.

* Baseband and Modem are interchangeable words/mean the same thing?

* The link in the OP for the tmobile HSPA+ fact sheet doesn't work. I couldn't find an updated link, do you guys have one?

* Searching the thread for San Diego, CA came up empty. Does anyone know if San Diego has been updated to HSPA+42?

* Loading the map on my device shows blue flags all over the ocean that should be on different states in the US. Is this happening to anyone else?

* It says on the OP "ONLY FLASH THESE RADIOS IF YOU ARE USING A MODEL SGH-T999(V) DEVICE!!!!!." I'm assuming that means T999 and T999V, but I just want to make sure

*I'm currently running FrostyJB 4.1.1 UVDLJA. Can I flash just the radios corresponding to 4.1.1, or am I able to flash any JB radio, meaning I can flash the most updated ones when they come out?

Thanks for your help, I really appreciate it.
[T-Mobile, Samsung Galaxy SIII] Perseus:
Is this the Stock Kernel Thread you are looking for ? There's one more thread for older kernels. Let me know if I need to dig it up.

My Question for you Doc if you please. One of the codes you posted here is *#2263#

This code allows you to unlock GSM & CDMA frequencies on the SGS3. Can you let me know which of the posted T-Mo Modem would allow such Unlocking ? Or they all will ?
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Correct

I just noticed this myself last night. I will either fix or remove it as soon as I can.

It most likely has. I will try to verify a little later, but in the meantime, try to google it.

I will have a look at this. You said when you load it on your device. Does that mean your tablet, smartphone, or PC?

Correct. Flash them to anything else or anything elses modem to the T999 and you will have a hard brick.

You can flash ANY radio, regardless of the ROM you are running. They are separate and will work as long as its the correct model device on the correct network. JB or ICS doesnt matter either way.

The link you posted is to the latest firmware. Its not a kernel thread.

I did find the one I was thinking about. Warlock posted it, but it was insecure stock kernels only. I dont think there is another, but if you know of one, by all means let me know!

I will take a look at the code and get back to you. Will probably be tomorrow before I can get into it much.

The modems themselves shouldnt be locked. I believe its related to the phone itself, not the firmware. If Im understanding what you are asking correctly.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
If anyone flashes the T999V Wind or Videotron VLDLL1 modem, please post confirmation that its working. I am un able to test it since I don't have the right phone.

Also, I still need the Mobilicity modem in case anyone is willing to pull it for me. Thanks!
[T-Mobile, Samsung Galaxy SIII] Perseus:
Ok My bad. I thought he had also a link for kernel alone. I will dig the other thread.

Basically there's this thread where they discussed steps to enable LTE, HSDPA etc on ATT or TMO phones. This code was discussed with the steps. But some people failed since they had different modems. Therefore my question. Appreciate if you could take a look into what the code does.

The T999 is the US model for tmobile. The T999V is the Canadian model used by Wind, Videotron and Mobilicity.

I would attribute that first to maintenance, then congestion, maybe other service issues and so on.
