Hi there,
I know there are no options to turn off just 4G in the stock rom (without also disabling 3G), so I was wondering, is there an option to use only 3G and not 4G in any of the custom roms?
If not, can we do this by using *#*#4636#*#* options?
Thanks...

No this is not possible. The reason you can turn off 4G on sprint phones is because their 4G is wimax while 3g is cdma so they are completely different technologies. Tmo, on the other hand, is using the same technology as 3g just basically upping the available bandwidth on 3g towers. I guess it may be possible for someone to modify a rom (or possibly it would be the kernel) to run only on 3g but then the phone would not be capable of 4G at all.
Not sure why you would want to anyway as, since it uses the same network, the only thing that would change is slower Internet. It would not improve battery life over just running on 4G.

I have crap reception in my building. I went into network and selected WCDMA only. So it never tried to do Edge. Amazingly my phone now stays with at least 2 bars of 4G in my building and the battery lasts longer because it is not always switching between. I swear it just wanted to go to EDGE all the time, but obviously there is a 4G signal here... I toggle off GPS and Auto Sync while I am at work on the quicksense it is a vast battery improvement.

Actually, I have found with phones in the past that the EDGE modem does use far less power, if it is possible to turn off the 3G/4G. But I'm still awaiting my Amaze and can't say if there are any options for this - probably not.
The reason I am asking this is because I want to use my phone in Turkey, and since there is no 4G here, I can only use 3G...
So then my question becomes; can I use this phone without problems?

Right, I'm saying switching between 3g and 4G would not save battery. Switching between 2g and 3g/4G does save battery.

Looking at the specs, it appears that the phone should support the international 3g signal. However I'm not sure if there is an international model. If not, the phone would have to be unlocked to access 3g.

BTW, I suggest that you update your XDA profile to include your country, so people can know where you are located - it can make a difference in the answers you get. For example, my posts show that I am on T-Mobile and here in the US.
So, if I understand correctly, with phones that use 4G WiMAX or LTE, 4g CAN be turned off since it is a separate system from 3G. But in phones that use 4G as an upgraded version of 3G, if 4G is disabled, so is 3G..?
I just fear that, the phone (unlocked) will constantly look for a 4G signal when used in Turkey, and it won't be able to find it, and so not connect properly...
I've used 2G in the last two days just to tried out baterry without 4G. What I did is go to Setting=>Wireless&Networks=>Mobile Networks=>Network Mode and chose GSM only - that gave me 2G signal only
You can use several apps to get a shortcut which lead you straight to Networks to save you some clicks: Better Cut, Bar Control, WidgetSoid (give you a toogle on home screen to switch) ect ....

There is no difference between 3g and 4g - the modem is in HSPDA mode either way. It just depends on the cell tower infrastructure as to which speed is achieved.
There is no way to "disable" 4g and use 3g only. It IS possible to disable 3g and use only 2g.

if it drops 4g it should automatically switch to 3g, if its not, its either cause you have no data reception at all at the time, or you have a screwed up phone, probably not the latter. There are some toggle apps you can look into on the market though, elixir is really good, and beautiful widgets has a 4g toggle i believe as well... hope this helps ya...

It's kicking my phone down too and showing 2G and after running a speed test it's like 200kbps. I haven't really tried to kick it over to 3G.

Your choices are 2G or 3G/4G. The 3G and 4G signals are essentially the same, both WCDMA. This is why you don't see a 3G icon, it is all wrapped into the 4G icon.
If you want to stop 4G data, you can download the widget from the market or go to Settings > Wireless & Networks >Mobile Networks > and change Network Mode to GSM only.

This.
4G and 3G use the same "part" of the network.
T-Mobile's network is not like Verizon or Sprint, where a completely different communication channel is being used.
The functionality is quite similar to WiFi...With 802.11 B and G, they use they same frequencies and talk on the same channels. However, 802.11 B tops out at 10Mbps, while G is capable of hitting (theoretically) 54mbps. The only caveat being that both the access point and the client, must support the updated protocol.
So yes, although it's doesn't seem logical, your choice is either 4G (HSDPA and HSDPA+) or 2G (EDGE).
If 3 and 4g are the same on Tmobile's network, then when you're on 4G, does it use any more battery than it does on 3G?
My user experience says yes. The battery hogging is on par with the EVO and Sprint's wimax. There was a switch to revert to 3G, and all sprint users that I knew never used 4G because it drained the battery in a matter of a few hours.
On an AT&T iPhone 3G, the battery never drained this quickly.
Please keep all question based threads in the Q&A section.

Someone correct me if I'm wrong.. But our 3g and 4g has no dependence on our radio. It's dependent on the signal we receive. So to answer your question, no power is saved because 3g and 4g use the same part of the phone. Only on 2g because a lower power radio is receiving the data signal
Over 10000!!! You bet I am.
I really like this phone but want to make sure that the LTE connection issues are able to be fixed with a software update. I hope Sprint isn't BS'ing on this. I have a couple of days to return the phone and want to make sure this is fixable before deciding to keep it.
Anyone know if the Sprint rep who said it's a software issue is telling the truth or BS?
At heart it is a good radio. No reason it shouldn't work as it's supposed to. So, the majority of the issue is software. And it is fixable. Maybe just as good as S3 and iPhone 5 LTE reception?
The big question here is if Sprint will actually fix it this time. Know that there were fixes for LTE in 2 previous ota's. To what extent they worked on it before, idk. Thinking that this time is make or break it.
So, the answer is wait and see. U can get out of contract if LTE doesn't work for u though. It's apart of your service plan. Gonna require persistence on your part to get out after the 14 days is up, but u can do it.
If I were u and needed a good LTE capable phone, I'd go with the S3. Because at this point, it is up in the air if it will receive LTE like it should in the near future.
Correction first update was wifi, second was lte lol
Hope so. Has to be software related since both this and the s3 have the same radio. And, since the airplane mode on/off trick gets it working, I'm lead to believe its software.

Airplane mode trick???
I really hope they can fix this. I decided to keep the phone after looking at the S3 screen and build quality I just couldn't switch. I really love the screen on this!! It is just as good as my wife's iPhone 5 in color reproduction. The S3 is nice but don't like PenTile as I can notice it and I don't like it when whites have a blue color to it.
The Evo LTE has the same SoC as the S3. If the Evo was having hardware problems with LTE so would the S3, but that is not the case (according to what I have been able to look up). Therefore it can be concluded that the LTE issues are software and not hardware.

AKA Airplane Mode Dance
If you are in an LTE area and your phone is stuck on 3G, or if your phone is on LTE and it drops back down to 3G, then toggling Airplane Mode ON and back OFF will make the radio scan and re-latch to LTE.
That's the problem with our EVOs, it's an LTE threshold and handoff problem.
I live right on the edge of LTE coverage, so my phone will handoff to 3G because it decides the LTE signal is too weak. The problem is, in my area a "weak" LTE signal is MUCH faster than a strong 3G signal. If I go into my radio options and choose "LTE only" it will hold LTE signal all day long. So the signal is there, albeit weak.
What we need is a software fix that will change our radio's signal threshold so that it will prioritize a weaker LTE signal over 3G.
I'm tired of doing the airplane mode dance. If LTE is available, I want my EVO to latch on and stay on it even if it's weak.

Thanks guys! Installing app now and have the data code saved for a rainy day as well
Edit : after switching to lte only, I get no data (voice or sms) but im able to run a speed test using 4g. I live in L.A. but I connect to an Albuquerque, New Mexico server I'm not sure what else I'm to do to enable lte only and keep data
It's NOT true for me that switching it to LTE only will keep it connected. I still only keep the connection for about 10 seconds and then it goes back to 3G. My understanding is that option in both *#*#4634#*#* and ##DATA# is "preferred mode." It will drop back to 3G.
And I know for sure that Sprint and HTC have an open ticket on this issue of aquiring and keeping an LTE signal. They will eventually get a fix out for it.
I used the network tool post earlier and set mine to cdma/lte... So I get 4g and voice/text.. no evdo. Which is fine by me because evdo sucks anyway lol.
Works great I now can keep 4g in my house like my gfs gs3 and not switch back to crap-do

It doesn't really work that way. 3g and 4g are independent connections that are maintained simultaneously. You're still connected to 3g even when 4g is connected. If you aren't getting 4g, then it simply isn't connecting to it and there really isn't much you can do about it.

Since I am on the latest ICS global firmware and a custom ROM, I not sure if if this location is still accurate, but go to settings-call-preferred network. When you get to this you should see a number of options. One is LTE only (4G setting) if that is what you want to do. However, if you do this, then you may not get a data connection if 4G is not available. Also, if you have a weak 4G signal, if will eat up your battery time.
You might try downloading a 4G Toggle program from Play Store. It will take you directly to phone settings. Even though I live in a 4G area, I actually leave my phone in 3G CDMA only mode unless I really need the 4G speed to download something. I get much better battery life.
You could try getting into the hidden phone settings and changing your prefered connection to CDMA, LTE which should disable 3g if i understand it right. That option should also save you a bit of battery life as well if it works.
You should be able to choose lte only from the hidden menu

Quick question. Is it possible to disable the LTE radio so it doesn't draw any power?
I live in an area which I suspect isn't going to be seeing any T-Mobile LTE towers for awhile, so at the moment the LTE radio is doing little more than draining power needlessly. I've already configured my phone to GSM/WCDMA mode, but does that actually disable the LTE radio? If not, is there any way that does?

Go to your phone and enter *#*#4636#*#*
This will bring up a test menu. Select Phone Information and then set the preferred network type to an option that does not support LTE. Try out the options and see if one works for you.
I don't think you can disable the radio in the fashion you mean.

No I have the official T-Mobile version, it is running the latest firmware and radio as of last week. Running AOSP ROM AICP.
I mean it could possibly be due to them working on towers but it still seems weird that the phone wouldn't try to connect to LTE when ever it is possibly available. It might be a placaebo effect, but it just seems like the phone has been having way more delays loading things, even if the ping is low in Speed Test.

When the phone is set to LTE/GSM it will monitor signal thresholds to try and keep you from having a poor experience on LTE at the fringe. So that if it detects your LTE signal is low it will move over to 4G or even 2G to try and provide you a better experience. When you set it to LTE only then it stays on LTE as long as you have usable signal.
T-Mobile probably has the threshold set too conservative, but that doesn't explain your poor experience on 4g (HSPA). I live in DFW and my HSPA service is fast.
Im in Dallas. Main travel area is old east dallas and north central / north east dallas..
I can tell you that im happy with both HSDPA+ and LTE with them.
on the rare occasion i have had a reception / speed issue i find that power cycling my phone fixed it. Also make sure if you do that you have FastBoot disabled.
Thats under power settings, make sure its not checked.
