T-Mobile Galaxy III not getting 4G any more

I've searched the forus but no such luck.
I just flashed FreeGS3 (GSM) Release 3 & since then i no longer get 4g.
My download speeds are around 0.18mbps
Any thoughts or help would be greatly appreciated.

I don't know what that is, but why not flash the stock rom to revert whatever you did? Or a Nandroid backup?
..Or maybe your throttled if you hit your data limit? It throttles to edge .. so those speeds would should about right..

I'm getting the same thing I even unrooted to see if that was the problem but 4g still didn't work, I've put this phone right next to my old epic4g and all I get is 3g speeds, I called sprint and they blamed it on their towers being upgraded for September when LTE comes out

Did you guys flash the radio by chance? Maybe that the issue? Just a thought. Hard to say not knowing what you did.

I just flashed blaser, no one else seems to have this problem with that rom

At&t galaxy s3 to T-Mobile help

I got my unlocked s3 so I can use it on T-Mobile and hate edge so I was wondering if flashing the blaze modem would allow me to get 4g like the at&t galaxy note did.

Blaze is a .gs2, it would probably brick. I wouldn't risk it. If anything I'd try the t-mobile .gs3 radio.

I been thinking...instead of messing with all that and end up with a brick, why just not sell it on ebay and buy an actual Tmobile one or maybe trade with someone willing to. I would look at the selling price for an AT&T GS3 on ebay and how much would a Tmobile run and if it's not that much difference then pay the difference than end up with a possible brick. Plus I have read some forums where if you flash some things that are not meant for your phone you can even mess up the IME on your phone with no way to flash it back at the moment until someone comes up with a solution for it.

Not trying to be a jerk. Just a friendly reminder that this is not development related and needs to be in general or QA. I would repost there and report your thread to a moderator before the pitch forks come out.

When I put my friends note to t mobile it was the modem you had to flash , if your set on doing it , read a bunch on ways to do the note WITHOUT a custom Rom then find the same files you use in that ( the modem and if I remember right there was one other thing ) then go to the t mobile section in the sgs 3 thread and ask for help finding those files , but do a lot of reading first cause it would be a shame to brick your awesome phone

buy the t-mobile version. it doesn't work hardware not supported

im looking into this as well, i had the att note and flashed the tmobile modem worked like a charm so now im looking to do same with s3. if i find anything ill let you know

I don't thonk it will work at all. Att's S3 is LTE, correct. Tmobiles is not. Two different hw radios used.
If you do try it please post your results for others!

I seriously wouldnt count on it. The two networks run on different technologies. Im pretty sure the hw is different due to this.
Sent from my SGH-T999 using xda app-developers app

Have you guys tried the radios in the dev section by wildchld? I'm not sure it will work either but maybe worth a try. It has a script that backs up current radio and you can revert back. Atleast on T-Mobile s3 it does. Just need to reflash the restore zip to go back to previous radio. Again try at your own risk. There's a huge chance you can brick your device.

I don't think it matters if the Gs3 from T-Mobile doesn't have LTE, I used to have my Galaxy s2 skyrocket with LTE running on T-Mobile 3G/4G off a GS2 Hercules Modem.

Then by all means, give it a shot. I have no problem being proven wrong on stuff like this!
Just remember that was a different phone. And tmobiles radio Im pretty sure was confirmed to NOT support LTE. So they are different.
I'm definately looking forward to hearing someones results after trying! Just do some research on the two radios, and make sure the sw modem is on the same partition for each phone. (I think it will be. But if its not you could end up with serious problems)
Good luck to whomever tries it!

Probably won't, the T-Mobile phone is pentaband so it will run 3/4G on AT&T, but their version isn't. Try it though.

My signal is horrible. Need help[Solved]

I have had this phone for about 4 or 5 days. When at my house I get 3g and only about 1 or 2 bars. This happened on my Samsung stratosphere too. Could this be a SIM card issue or hardware. I have read about a lot of people replacing this phone and still getting issues with signal. If I do bring my phone in to a Verizon store to get a sim card do I have to revert my phone to stock? I don't know if I should send my phone back or if where I live is just horrible for data. Sorry for so many questions.

Flash another baseband radio and if you are using custom rom with custom kernel then flash stock galaxy nexus's kernel.

Since it is the case for two phones, then maybe the 3G coverage is not good in your place.
Try asking others living around to confirm if they also suffer the same 3G coverage problem. Also try in another place to see if it still shows a weak signal everywhere or only at your place.

I do get better signals in different areas. Even with the 3g and 1 bar my speeds for browsing are decent but I just was wondering if a sim card or replacement would help. Thanks and I will ask some people

If you would like to try another baseband radio as suggested by manumanfred then this thread should help you if you have a Verizon Galaxy Nexus as it seems
Check this for baseband radios if you have a GSM Galaxy Nexus

I flashed the 4.0.4 radios and they didn't change. Should I try flashing again?

Flashing radios makes a slight, if at all a difference. Your best bet would be to keep calling and complaining to your provider, ive seen some success stories where others have been able to get verizon/att to pay for a 3g extender

Edit:Alright thanks. I think I am just in a bad area and I use wifi at my house anyways. Thanks
I accidentally misread the radio labels. The 4.0.4 did install.

I am not sure that an old radio will perform better than the newer one. Give them a try then choose the one that suits you better

Well I am going to have to switch back to the latest. Data barely turns on when on these 4.0.4 radios. I am not going to return my phone because I doubt mine is defective. Thanks to everyone for helping

It would be great if you mark this thread solved by adding something like "[SOLVED]" at the beginning of the current title
One more thing please is to make a habit of hitting the "Thanks" button to those who help you
Good Luck

4.0.4 radios are old. Try running something a little newer. I'm using FC04/FC05. Although honestly I don't really see a difference. Most of the time it just adjusts the timings between switching in and out of 4G... which I have disabled.
I would also recommend looking at a cellular booster/repeater. I work underground in the bottom floor of an office complex and we don't get signal from any carrier. We paid like $200 for a repeater and now we're good.

Can You Develop 4G LTE Only Option On Sprint Nexus?

I am posting here because it seams no one knows why some phones have LTE only options and some do not.
I was wondering if someone can develop this feature somehow if the user is rooted and has there MSL code that doesn't have the LTE only option by Default.
Is this possible via development and if not why?

The only problem with going to LTE only is, on Sprint, LTE only supports data service. So if you went to LTE only you would lose voice service.

I want to lose my voice services. I just want to use my phone as a Data access point.
So do you know if someone can develop this feature?

ah ok, wasnt really clear in your explanation. any of the custom roms i have used i don't ever remember seeing lte only. sorry man wish i could help a little better.

It's possible to have LTE only, yet not many people can develop radios that shut out normal service. Good idea
Though!
Sent from my Galaxy Nexus using xda premium

Ya what if some one developed a ROM feature to where you can at least disable 3G so the phone could only connect to LTE. This could bypass the possible hardware limitations.
Sent from my Galaxy Nexus using XDA Premium App

Probably won't work but use efrants return to stock guide and instead of flashing both radios try flashing the LTE radio only and see what that gets you
Bloods thicker than water

I wonder why this is not more popular and why more people are not working on this possibility.
Sent from my Galaxy Nexus using XDA Premium App

Search in the Play Store for "Network" by Philipp Mangelow. It is actually a shortcut to the phone's built in diagnostics mode. It doesn't work for stock or ROMs with stock kernels, but I have used it to put the phone into LTE-only mode for testing. You will see both GSM and CDMA settings, regardless of which one your phone is. Try them all, sometimes the setting is mislabeled (its a bug with the ROM, not the app).
So in short, even if your ROM doesn't support LTE-only, you have a good chance of this feature with this app.

Okay there was nine options under preferred network tab and all of them did not force LTE. I do not know if I have to reboot or not but if you know anything else that would be great or have any other ideas.
Also there was something about ims registration but I do not know anything about that.

The LTE option only appears on certain ROMs. I forgot which ones, and I can't check right now because I flashed back to stock so I can take my phone to Sprint for repairs (overheating). Try Eclipse, Maddoggin, Carbon, Rasbean, or Jellybro. One of those will have an LTE option I'm sure. What I do is set the LTE option, then below I turn off the radio, and then turn it back on. Oh and sometimes the 4G icon doesn't appear, depending on the ROM, but if you do a speedtest you'll obviously see you're connected to LTE.

Okay I have tried all of them by turning off the radio and turning them back on. Also did not pay attention to names. It still did not work so I guess I will have to try one of those Roms.
Do you know if I can install one of those ROMs with the sprint nexus toolkit? And which ROM would you suggests first.
Also im afraid it might be a hardware issue do you think that is possible? Maybe I got one of the first Sprint 4G LTE Nexuses that you can't split the LTE signal.

no he didnt need to. that is why i reported them.

It takes about the same time to answer a question than to b*tch about it...
ANSWER: Download and flash Eclipse 2.1 ROM (Android 4.1.2) :good:
It has the LTE ONLY option you want. It also has a fantastic array of options and tweaks, and 2-4 times the battery life of a 4.2 ROM or Stock OTA. :highfive:
If the LTE ONLY option doesn't work on the the first try, use the Network app posted above to turn off the radio and back on again. :victory:

Using my T989 on AT&T

I am going to be passing down my unlocked S2 to my girlfriend that is currently(for now) on ATT. I am running "Jedi Bean" now and just like everyone else on a 4.1 ROM, I dont have signal strength bars.
My question are:
*Is there anyway for me to get Signal strength bars with a T989 on ATT?
*Should, or could I even, flash an ATT radio? Would it help reception on ATT?
Please give me some ideas as to what I can do to make my T989 run as flawless, and as "normal", as possible on ATT's network.

I know it cant get 4G, but I thought the T989 is capable of 3G on AT&T, it has the band for it...The main reason I am giving my girlfriend the S2 is so she can have all the Samsung apps and enjoy a better phone than she has; currently an HTC Inspire. I dont want to sell/trade it is because its my spare phone now that I sold my Galaxy S.
Side note: My girlfriend barely uses data, so the reduced speed is not a big deal.

It gets 3g on at&t because occasionally when I go out of my hspa 4g range like in middle of nowhere my phone will link up to an at&t tower on the edge network which is technically 3g. Sometimes its gprs 2g but it does get 3g on at&t signal.
