So, I'm having trouble getting a reliable 4G signal. I'm in the Chicago area, so I think 4G coverage should be pretty good. I also asked a guy I work with who has T-Mo, and he said his 4G is good. Could the ROM affect it at all, or is it just the radio? Speeds also seem pretty good, so I can't figure out if it's maybe just the icons.
Could be a radio/modem issue try flashing a different modem like the blaze modem also check your mobile network settings
You can find most of the modems here http://forum.xda-developers.com/showthread.php?t=1426001

What about my network settings specifically?
Also, I replied in that thread (still the last post). I seem to have trouble flashing those.
I want to install the official UVDLJA T-Mobile Rom on my Galaxy S3 and then install Frosty Jb. I have the T999v of Videotron one. Will my phone gonna be bricked or not? And my network gonna work also?
Thank you

You're doomed bro. Turn back immediately.
Should be fine as long as you dont change your modem. I suggest you use mobile odin and unselect the modem. I did this with my t999v wind mobile and its fine.
I asked the same question with similar responses. But could those that had success maybe give a bit more detail on how they managed to odin the TMO stock? It passes the md5 but then fails when flashing, I have flashed numerous times in odin with no problem. Maybe an obvious requirement I am not aware of (stock recovery stock download or some such thing)
Thanks for the answer. I have another question. Before I turn to Frosty, my mobile network was only 3G and H+ but now with frosty, its only the 4G icon. So with frosty im on real 4g or its only a "fake" icon?

Used Mobile Odin and de-selected MODEM and RECOVERY worked great. Thanks for the tip!

T-Mobile has no real 4g. Some roms are coded to just show E and 4g for 3g, H, and H+, while other roms break it down more

Well, how much data have you used? You could be getting throttled especially if you've used lots of data in short amount of time.

T999UVLH2 is your baseband version. Then i would try flashing the T999UVDLJC baseband and test it out.
There is a new mdm5 baseband out. Im sure you cant search and find it here.
I flashed wicked v10 on my friends tmo s3, were getting slow speeds as well. Gonna try a different radio

I have the same problem in a certain part of Seattle where my hspa+ speed is around 4 - 10 kilobytes per second download..
Guess to many people using it
I don't think it's the rom itself. Try a different modem and report the findings. I'm on Wicked v10 in souther cali with latest modem and I'm getting great speeds. Can it be on tmobile end updating/refarming towers?

Click the link for Basebands/Modems thread in my sig. All flashable modems and a plethora of info about them is there.
Feel free to ask if you have questions. The thread is stickied in development if you need to find it later.

Wow I was just trying to find out if others are having the same problem and Bam I see this. My download speeds start high then go slow. Hopefully it's the modem
I noticed it didn't start until I used the new T999UVDMD5
Edit: nope tried other modems and problem is still there

Do you get different results during different times of day? Could be network traffic. Or if they're doing work on any towers it could also cause problems like that.

Indeed tmobile is upgrading their hardware and adding towers now that their LTE is spreading to more cities. Also since the merger didn't go through with At&t they are upgrading to compete in general.

No same results at any time of day and i also noticed it did start happening until i flashed the t999uvdmd5 but since then used different ones but same results

Call support to see if they are working on the network in your area.
If not, try the other modems in my baseband thread.

I tried the MC3 today. After installing I was able to pick up a weak signal but as soon as I walked around the house the signal dropped. At the office i had a better signal using the old modem vs MC3. I think I will try the one for t mobile. Thxs

Bajanman,
You saved me several hours. I will download the older ATT modems and see if that works.
I tried one of the old modems and got the same results. I continue to get varying degrees of signal strength. I saw some people saying this could be a hardware issue , any ideas.

That could possibly be it.. could be hardware based problem.
But first what modem do you have now?? J2 is the first one

Bajanman,
I tried all the modems available for ATT with the same results. I have a very weak signal especially indoors and depending on where I am it improves. What kind of hardware problem do you expect to be the problem? Is there any way to check this?
Thxs
Ive noticed since I moved offices, that in my office building I get absolutely no service whatsoever. And there is no wifi password available to use wifi via my phone. So today as I was leaving work and finally got service again, I had 12 missed calls, 5 texts, and 3 voicemails. Is there a better modem to flash that can help? Thanks!
Not exactly. Different locations have different best modems. You just have to try them and see.

Could anyone suggest an updated modem, or one they have had luck with if they are from the Chicago-land area?
You could check the map in the modem thread too. I know its a jumbled mess now, but the info can still be useful.

Do you think you could message me about what modem/radio might work better once that forum is sorted out? It really sucks not being able to use my phone at work for 8 hours. Thanks
I may not be able to unfortunately. I messed around a little before and got nowhere. May have to start a new map.
Have you checked T-Mobiles coverage map yet? There just may not be a signal there in the first place.

I never had a problem with my Blaze there. Even at home with the S3 I get maybe 2 bars. Which leads me to believe its the modem. On my Blaze I had an updated modem that made data very fast.
Can I use UVLI6 which is a 4.1.1 modem on a 4.1.2 rom I am currently using? Would that be compatible? i cant remember which way compatibility goes :/
Any modem, any rom, any build. Only make sure you use the right models modems, which it sounds like you are

It will work, but last time I did that I wasn't able to connect to hspa or hspa+ only umts.. If it gives you signal though I guess its better than nothing

You can use any modem version as long as it's specifically for your phone.

This is just strange... in roughly a year of doing this I think you're the first to report that happening. 4.0.4 and 4.1.1 modems have always worked on 4.1.2, and any other combo has worked as well. There are people who still use the LH2 (ics) modem because it still performs better than any other for them.
I think you may have been seeing it function normally though. When idle, its supposed to drop to UMTS to save power and bandwidth. If you check while a transfer is occurring you will see it change to HSPAP.

Has anyone else found another modem that they now use that gives them better signal/data speeds for their Tmobile T999? My work building is a complete dead zone for Tmobile, so I am hoping flashing another modem works. Otherwise, im not sure what else I can do.
I have to refer you to my initial response here. A modem that gives better speed and signal for me, might be one of the worst for you.
Just something to consider, you probably could test 2-3 different ones each day at work. Maybe more. If your main issue is signal, then flash, check service, if none then flash another right away. I could probably flash 5 different ones on a 15 min break if I was only looking for improved signal. Might be a better way than waiting for someone to tell you what worked for them, then testing only that the next day. Its your phone and your time though, so its your call. Just tryin to help
