3G/4G Menu

Where is the hidden menu for the 4g preferred setting? Isn't there a hidden setting menu. My phone tried to stay on edge. My little brother has a blaze and is right next to me and his is on 4g and mine is on edge....
I still have IMEI so that isnt the issue. :good:

go to the play market and download phone info

Should it be set to gsm/cdma auto(Prl)?
It was on gsm auto (Prl).
It seems since I flashed a Rom and then did my Nan restore to stock rooted it preferred edge over 4g.

no if you want it to prefer 4g ovr edge then you have to have it set to wcdma preferred. that's tmobile's 4g! and then when it isn't available it will simply go to edge. that's definitely your best bet.

I did that now. It still was sticking on edge. I then switched it to wcdma only and it switched right to 4g. Thing is on edge it had full bars. 4g only two. I wonder if that's why it stayed on edge. Anyone know?

So I'm visiting family in Toms River NJ and I have full bars of Edge service, but no 4G service. Should I try switching network settings or what ??

try wcdma preferred. It helps stay on 4g. There may not be 4g where you are. Might want to check on that.

So I did this same thing and it's telling me I'm on 3G.
When I was on completely stock ROM out of the box, I was on "4G" all the time.
Now, every ROM I've flashed to test out which one I like, it displays 3G BUT whenever I click on a link it switches to H+. Then when that link is done loading it switches back to displaying 3G. Am I correct in assuming that it is supposed to do this?
Edit - After reading the NEXT post while I was doing my search, it seems that I was correct. :]

correct you are. while It's accessing data it goes to H+

I have my set to wcdma preferred. Keep in mind this setting might use more battery because it's constantly looking for four g signal rather than two g or three g

If I'm not mistaken, on stock it will always show 4G, even on 3G.
A lot of custom roms change this so it tells the truth. That's why you see 3G or H/H+.

Are you inside a building? Bell's LTE penetration is....enough said.

Did you get LTE with stock rom? If so it could be a setting in the rom somewhere. I also have troubles with LTE when in a building (if thats the case)

I've been outside a building and still don't get lte in the kitchener Guelph area where lte is supported I also changed the settings to gsm/lte but still never see 4G on the top

I'm on Virgin Mobile Canada (Bell) and was having issues getting 4G (LTE). I believe it was posted on the CM10 thread but I reposted this as someone else was asking the same thing, but if you can't get 4G working even with the correct APN, go to your dialer and dial *#*#4636#*#*
This will take you to the phone testing menu. Tap Phone information, scroll down to the selectable list which may say CDMA or GSM/CDMA. Change that to LTE/GSM or LTE/GSM/CDMA and that should get it working again.
This worked for me on CM10, but AOKP should be close enough that this may help you out.

I'm on Att but the 9-8 build of aokp defaults to wcdma preferred on boot up..I know I live in an LTE area so what I did was *#*#4636#*#* then choose LTE only to force it into LTE coverage after that choose LTE/GSM/CDMA prl auto then or LTE should stick..for me if I chose LTE/GSM/CDMA first it would still default to wcdma...hope this helps...keep in mind you have to perform this after every reboot until its changed by task if it ever is in future builds.

Hmmm, that's interesting. On CM10, I don't need to change that on every reboot. Not even after a dirty flash. Just after a clean flash.

I had the same problem on rogers in Vancouver also running cm10 make sure you change your APN to the lte version also where it says APN type I put default. Another thing that may confuse you is that there is no lte icon on cm10 it says 4g instead

Also what might help is don't keep to many APN stored delete all except the lte and the lte tethering one. My phone was also switching to the regular APN on booting it up

I can only access H+ and not LTE

I recently got a LTE sim card, and an LTE data plan with Fido. 4G worked for about 5 seconds (I even did a speed test) and then now it's permanently on H+.
APN is set to LTEmobile.APN but when I change to Network Mode LTE/GSM, my signal goes blank and stays like that until I go back to GSM/WCDMA, which doesn't make any sense.
I'm using Task's 10/28 Build, which is the only build that doesn't have black screen unlock.
I tried updating to his latest 4.2 but LTE still didn't work.
Any ideas on what is wrong?

did you not read what he said? He has an LTE sim card. To the OP try a google search and see if there are any different apn's. Its not rom related because task650 gets LTE speeds with his rom. Or if your phone is unlocked and you know someone else that has the same phone or LTE sim card pop it in and try it out

Some ROMs have incorrect Fido/Rogers APN settings; I'd go over what's in the ltemobile.apn settings and compare it to a known good set (such as the ones in the stock ROM).

Soft bricked my phone by going back to rooted stock ROM through Odin. Guessing I should have formated system. Anyways fixed it up. Got lte working on rooted stock. Then when to miui no lte. Read that lte is a problem with many on this ROM so I lose. Hope I can get it working eventually when off stock.

Carriers use different labels for H+/LTE - ROMs differ in how they interpret the actual signal speed.
Some ROMs accurately reflect the network speed, some don't.
Some carriers promote/sell speeds that they cannot provide in every area.
There are many possible explanations as to why you are experiencing this.
You should provide your ROM, carrier, APN settings, network speedtest results, etc. for more in-depth answers.

[Q] LTE = H+ for I9505 roms?

I was wondering if the H+ symbol I get for the Omega rom means it is LTE? There are times when it says E, 3G and 4G as well. I'm assuming the H+ is when it is on LTE here in Chicago.

I Would like to add, on TMO rom it seemed to me like they are marking H+ as 4G as well, which on normal roms (i9505) they are not.
i had 2 Galaxy S4 in my hand, one with TMO rom and one with i9505 rom. (With TMO sim in both)
the TMO showed up 4G and the i9505 showed H+
but when looking inside the debug menu, they both were in H+ channel,
speedtest showed the same speed as well.
so what i think is that TMO is "Cheating" by stating "i'm on 4G network" which should be only LTE,
but you are on 3.5G network (H+)

you could also correct that by just changing the build.prop lines to the tmobile values and you get your normal icons back for 4G and 4GLTE. I did this since I am running Omega as well.

I honestly do not know that this will work on an AOSP rom. My bet is that they probably wouldn't- and if you're running an AOSP rom built for the M919 you'd already have the correct build.prop values:
ro.product.model= SGH-M919
ro.product.name=jfltetmo
ro.product.device=jfltetmo

How do you change the build prop? Also, will this effect the changes I made with 3 minit settings?

I'm on omega. Change your build prop to get T-Mobile icons. You could also go in settings/status and check if your in hspa or LTE. I have LTE now in Cleveland and see 4g LTE for my data icons

A simple text editor works, it's located at /build.prop
Otherwise there are several options on Play, just search for build prop.

Thanks i changed the name, model, and device in build prop, but it still uses 3g and 4g.
Nevermind it now. Shows lte for lte and 4g for hspa after the edit of the build prop

Tmobile's 4g has always been hspa+ They are just starting to roll out LTE. AT&T did this also. They billed hspa+ as 4g, and then rolled out LTE later, which they currently market to compete with verizons 4g lte. Gsm carriers were able to debut hspa+ faster then verizon was able to debut LTE for the first time, giving them a leg up on the fastest network for a short time.

TMO rom /w LTE support

I'm in a real pickle. I have a AT&T (I747) S3 that's capable of LTE. I've flashed several T-mobile rom's on it and everything seems to work except I don't get an option to choose LTE in the Mobile Networks. I assume this is because T999 did not have LTE but T999L did.
Are there any roms that are touchwiz (I need wifi calling) and also support LTE?
Thanks folks!

Um... Why haven't you tried at&t ROMs if you don't have a t999* device anyway?
Sent from my SGH-T999 using Tapatalk

Because AT&T roms don't have Wifi-Calling feature. I should have clarified T-Mobile is my carrier.
I was able to figure this out. I downloaded this 4.3 Stock deoxed ROM for T999L and I was able to get everything working. Now onto theming it like an S5. Unfortunately majority of the custom roms out are for the T999 and don't support LTE. http://click.xda-developers.com/api/click?format=go&jsonp=vglnk_jsonp_14033932361886&key=f0a7f91912ae2b52e0700f73990eb321&libId=e2cc1c90-f9dd-49fc-b098-d6b1401acb32&loc=http%3A%2F%2Fforum.xda-developers.com%2Fshowthread.php%3Ft%3D2561670%26page%3D7&v=1&out=http%3A%2F%2Fwww.androidfilehost.com%2F%3Ffid%3D23252070760975307&ref=http%3A%2F%2Fforum.xda-developers.com%2Fshowthread.php%3Ft%3D2561670%26page%3D8&title=4.3%20Update%20for%20T999L%20now%20live%20-%20Page%207%20-%20xda-developers&txt=%3Cfont%20color%3D%22Blue%22%3ET999L_4.3_UVUBMK4_deodexed_KnoxFREE.zip%3C%2Ffont%3E

I still can't seem to get LTE on this AT&T S3 (/w AWS enabled). In the same area I'm able to pickup LTE on another AT&T S4 (/w AWS enabled). I'm able to pick up Edge and HSPA+ on both.

UPDATE: I was able to connect to LTE but I had to force the phone to use LTE Band 4 using *#BAND#. I was not able to make any calls at this point since it was the modem was running LTE only.
I then moved the modem to Automatic and the LTE remained and I was able to make some calls but on ending them, it went straight to Edge instead of HSPA+ or LTE.
The switch over between Edge to HSPA+ / LTE doesn't seem as smooth as the S4 and sometimes it just doesn't switch and sticks to Edge.
Ideas?

People have been trying to do this for a while and it is something I believe just isnt going to work. The I747 was built to use a specific set of frequencies on AT&T networks. T-Mobile uses different frequencies/bands and the I747 simply cannot make proper use of them. There's threads in AT&T forums about this. You should check them out.

I used an I747 before with T999 ROMs and had no problems connecting to LTE once I used the correct APN, can you please state what APN you are using?
Sent from my SGH-M919 using Tapatalk

Ok, I have realized that this is an error caused by the AWS patch going away when I reboot. I thought this wasn't supposed to happen with I747 and only with i747M's but it seems like it's happening to my unit.
Once I have the AWS patch on, it goes quickly from E - > 4G (HSPA+ - > LTE (when available). When the HSPA+ is only available, it has a much harder time moving from E-> LTE directly.
