I just got my T999 on Wednesday and on my stock ROM I had the original baseband but my IMEI sv was 03. After flashing the route66 ROM it's now at 02, same baseband....?

Made the mods above and wow. With newest modem
[T-Mobile, Samsung Galaxy SIII] aznmode:
It looks like FreeGS3 R6 already has this changed in his build.prop. His current ROM is already bases off UVLG1 so I'm not sure if that's default.

Can anyone share his Canadian wind version modem backup file.cuz I loose mine.I can't able to connect to my carrier wind.plz help guys
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
For those who have not seen any difference after flashing the new radio you can try this: open your build.prop file and make your corresponding lines match these

ro.ril.gprsclass=32

ro.ril.hsupa.category=8

ro.ril.hsdpa.category=36

These have significantly improved my speeds, and while not as consistant as id like, its still much better than before! Share your results if you give it a try!

I'm still messing around with the settings in hopes of finding something more consistent. Ill update my findings after I've had some more time to test.
[T-Mobile, Samsung Galaxy SIII] paullu:
i just flash it and data speed got slower!!

i am on cm9 NYC
[T-Mobile, Samsung Galaxy SIII] layzer253:
Quick question, if I use this modem, do I have to reflash it after changing roms? Back in the vibrant days that was necessary.
[T-Mobile, Samsung Galaxy SIII] aznmode:
Not necessary. I've flashed 3 other roms already and didn't have to reflash the radio.
[T-Mobile, Samsung Galaxy SIII] layzer253:
Cool, thank you.
[T-Mobile, Samsung Galaxy SIII] SimPRoBer20:
After a week of testing I find this does increase speed but it takes longer to establish the connection to h+ leading to longer waits to bring up what u r looking for. So in my case stock modem is faster.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Has anyone tried these build.prop edits?? Ill probably work on it a little more tonight now that I'm back home, but am very curious if anyone got similar results as I did with my testing.

I have heard that a couple people couldn't boot after editing build.prop, also heard it was most likely due to their file manager not saving the file correctly. I use root explorer and heard super manager works well too and i never have had a problem.

Anyway, make sure you have a nandroid and if you have a problem you should be able to just restore the system backup and not lose your data or settings.

Point of interest to me: I have done lots of these ro.ril edits on my last phone and now on this one. I have noticed that depending on my location different values in the build.prop give different results. I'm guessing that it depends on the tower you are connected to, but that's all it is...a guess. (Always tested with full signal) Values that are fantastic at my house may not work as well or may even work better a few miles away, and then provide entirely different results just outside of town. On my last phone I had several copies of the build.prop to use depending where I was. If anyone has any other info on any of this, or any ideas to try out, id be most happy to hear about it!

Ultimately id like to find a way to have consistancy regardless of location without having to sacrifice the higher speeds the phone is capable of.
[T-Mobile, Samsung Galaxy SIII] george241312:
Mine too lol NY bx however speeds are more consistent now the ping stays lower then 100ms sometimes on speed test the ping goes over 1000 ... now with new radio no moar of that..

[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
The ping gets high because when you are not transmitting data the phone drops to 3G, and it can take a few moments to jump back up to H+. That few moments is where your ping time gets high and then it should jump to H+ for the rest of the test. I'm not sure now if there's a way to make it either stay on H+ or at least make that jump quicker.

As for your speeds getting slower with the new radio, try some of the build.prop tweaks I mentioned. You may be surprised, but you won't know unless you try! Keep a copy of the original on sd if your worried about going back to orig values.
[T-Mobile, Samsung Galaxy SIII] Pete7ate:
Really is a good thread, very useful.
[T-Mobile, Samsung Galaxy SIII] Wildchld:
Your on the right track but like you said consistency is a problem also depends on that service is available in your area like downtown I get better speed than out where I live
[T-Mobile, Samsung Galaxy SIII] Cobra281:
so you're supposed to flash the TMOGalaxyS3UVLG1Modem.zip ONLY, right? the TMOGalaxyS3RestoreModem.zip file is only if your modem did not get backed up, due to flashing the modem twice- or if you want to revert back the old T999UVALG1 modem\baseband? where does your backup save? and what is the 60mb modem.backup file for?
[T-Mobile, Samsung Galaxy SIII] qpinto:
Yes flash the 19mb file. It will make a back up of your old radio for you. Only flash the recovery zip if you want to go back to the old radio. You can flash back and forth as you please.
[T-Mobile, Samsung Galaxy SIII] Android_Monsters:
this modem works good in Austin.
[T-Mobile, Samsung Galaxy SIII] DoNutsDC:
So, with those of us who don't have these lines in our build.prop, where would we add these to test out? Ever since I lost my IMEI back in late July, I haven't been able to get speeds above 4Mbps. Just wondering if this would fix the issue. Thanks in advance.
[T-Mobile, Samsung Galaxy SIII] Wildchld:
They should be in every build.prop just not the same numbers

But at the end is fine
[T-Mobile, Samsung Galaxy SIII] DoNutsDC:
Thanks Wildchild, just making sure because for some reason, I just really don't see those string in mine. Currently running CM9 Nightly and I was a bit concerned. I don't want to end up borking something. Thanks for the help, adding lines in now.
[T-Mobile, Samsung Galaxy SIII] Wildchld:
Ahh CM9 and CM10 they don't use it that's why you can still try and see should hurt. From what I have heard is the OS stability is first then they will work on the rest.

Yep, you are correct: nothing happened. Thanks for the tip anyways!

Why not use the new radio. I've used both on freegs3 r6(based on UVLG1 rom) and are the same as far as speed and reception. Atleast you'll be using the right radio.

Whoop, pulling in 2 mbps down more than usual (getting 10 instead of 8).

Does the modem affect WiFi signal as well? Or just the Carrier reception?

[T-Mobile, Samsung Galaxy SIII] spodie:
This may be a stupid question but since H2 is a leak.... does this mean that this radio is also a leak which will be changed during official ota? Or is this the official modem that will come when official H2 is released ?

P.S. why back up a previous modem when u can just reflash it?
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
The whole update is a leak. Leaks generally come with no documentation. There is simply no way to know until the official release.

If its ever part of a leaked file, consider it a leak, and therefore not final. It will likely change in official release.
[T-Mobile, Samsung Galaxy SIII] Wildchld:
Actually H2 is an official build it was just put on updated G3's. I had someone send me the system and modem images. BTW I'm getting to your PM

Oh ok. Sorry I missed that! Thanks for the correction.

No rush on responding to the pm. Whenever you have time. I just mentioned it because there have been two I sent this week that were never received. Figured this way youd let me know if you didn't get it.

Ouch. Not a good choice for everyone.

I'm in Hollywood, on the 4th floor of a building with a clear view and full 4G bars. You can tell from where I went from the last radio to this radio. . .

Not sure where everyone is with better performance but this cut my speeds to 25% of their original speed. No good. Going back. . . Wish I could see some 20Mbps in Los Angeles. We're only a major market. . . :-\

Update: returning to the last modem and I'm already back to 9.26 Mbps so I think I'll skip this one.

I noticed when I was actually running the jb leak my speeds were awesome. Fastest I've gotten actually. But with this modem and ics speeds are not great. I'm sure it has to do with the ril files in the leak. Probably different than the ones in ics.

When I'm doing a speedtest.net app something strange happens. The first .25 of the test is normal ups and downs, then the remaining .75 percent is just a straight line for the download portion. It's as if the test is getting cut short instead of testing thoroughly until completion. The speeds are just alright. Not high like I'm used to. Maybe it's just the specific tower that I'm close to right now and will have to test around in some other areas to see if it's phone specific or not. Anyhow, thanks for sharing Wildchild.

I'm with the same set up, Sonic + H3 ....however.... Before I flashed H3 I was on the H2 kernal (sonic stock) and I have a feeling that the H2 was a lot faster and more stable with the data speeds.

Flashed UVDLH3 and I had 6365, 2945, and 1183 on three runs.

Immediately flashed back to LH2 and ran the test again and I had 17688.

I'm sticking with LH2.

[T-Mobile, Samsung Galaxy SIII] iunlock:
Ahhhh you guys got me thinking now.....

Well although it all depends on ones area, there's one place I really want to test out where I get 0-1 bars at best.

My intuition tells me that LH2 will be faster....in the meantime I'll stick with LH3 until I get to that area....

Will report back....
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Heres my theory.

The LH3 radio was built for jb. So chances are its not working as well because the overall system and the way the modem works with it have changed.

Im wondering if you were on the jb leak would the LH3 then perform better?

Then again, so far it has seemed like each radio has performed differently for many different phones and locations. Some people are still getting their best speeds on LG1, so ymmv.

yeah it sucks, dunno why.. i get like 2-3 bars of 4g by morton grove, skokie and 0 bars at my house on 4g lol.. did they tell you anything that might remedy it? like did they say that they would send a tech to a tower or something to help reception at your place?

Wow I would be happy if I can get 3g around gross point and bronx lmao. I'm always full bars in Morton grove and everywhere else.

Yes, those tests are on the H3 modem and my place in south seattle. I would get 0-1 bar at her place in Pacific (near auburn super mall), and now I get 2-3. I haven't done a speed test there, but I'm now able to reliably use my data connection there.

Oh, really! You should make a trip here to Portland, lol. I flashed this modem two days ago not for speed but in the vain hope I can get signals in all the dead spots I have to go to. It cripples this awesome phone and drives me crazy. So far I've noticed I can get a strong "E" in an area where I was getting no bars at all. I'll wait until I can test some more, however, before I decide to stick with it. The interesting thing is that with UVLAH2, all the problems I had with wifi-calling on UVALEM pretty much disappeared, so I'll have to figure that in too.

I flashed to LH3 -> Then restored back to LH2 -> I still see the modem file....

so if I wanted to go back to LH3, just reflash the existing file I see on my SD?

Any draw backs from jumping back and forth?

What will happen to the restore file? Not that it really matters I guess... :)

No real drawbacks from flashing modems. Its the only real way to test!
