i managed to get my captivate rooted last night and now i no longer have 4g it was replaced by an h+ and my internet only works now if the h+ is visable on the screen witch happens to be like 2 times a day for maby 3 or 4 min. how can i get my 4g back?
well for now im unrooting it and going back tot he stock rom to get my 4g back if anyone knows of the fix please let me know of it
The Captivate Glide isn't capable of actual 4G. The "4G" logo you're seeing is in reality HSPA+. Whatever custom ROM you had just said HSPA+ instead of "4G". HSPA+ is considered "4G" by AT&T.

something was wrong for sure. the stock rom saying 4g even if it is the same the stock rom still did my internet even without the 4g icon present where as the rooted stock rom would only connect online if the h+ was on the screen next to the signal bars. how could i get the internet working better on the rooted rom?
got it. installed cwm anp used a different rom. working great now.

I have the T989D from Telus in canada, and every single rom ive tried(cause theyre just modified t-mobiles)..says 3g instead of 4g. I was wondering if there was a way to fix this?
Thanks!

Did you try running a speed test? I am definitely getting 4G speeds even though it says 3G. I'm not sure why this happens.
it's just a bug in the icons
the speed is not affected
i wont be able to test that util later this week, as where i am right now gets like 5 megs tops no matter what

Lol that is definitely 4G speed still. 3G speed.. sucks
You know that HSPA+ is actually 3G right? To the phone it connects on the same frequencies and uses the same method, just uses a wider connection channel.
That's why a custom ROM identifies as '3G', Telus wrote some custom features into the OS that makes it show up as 4G.
Basically, they replaced the 3G icon with a 4G icon. The 3G icon never shows up on stock Telus.
I have my APN settings all set up. I am in a 4G area. I was getting 4G prior to flashing CM. I'm now only getting 3G. Any suggestions?

Does Straight Talk even support LTE? 4G on CM roms is LTE but 4G on stock AT&T roms is H+.

Straight Talk does support 4G (HSPA+) but does not support LTE. I was on the stock out of the box rom and I was getting 4G so I believe that 4G is HSPA and LTE is of course 4G LTE. Anyways the link from the previous posts claims in 4.2 that the data connection is slowed down when in idle but when strain is used on mobile data, the phone will automatically bump up to 4G (HSPA) , I am in 4G area.
On ANY AOSP ROMs, 4G is LTE. If you are on HSPA+ it will show HSPA+. Phone companies showing that their HSPA+ is 4G on stock ROMs is a lie. So, if it shows HSPA+ as your connection, then you are getting what phone companies call "4G." Thanks.
HSPA on Strait Talk
I also have Strait Talk and can say that HSPA/HSPA+ has not worked for me on CM10.1 however it was working on CM10 on a AT&T GS3, and it works on my Wife's GS2 Skyrocket(Stock).

Same here. No issues whatsoever under CM10.0 - was consistently getting H+ (which was fine for me). Upgraded to CM10.1 today and can't get anything better than 3G.
If I do need to flash a new modem, can someone suggest a link or other reference. Looked around all afternoon but couldn't find anything helpful.

Hey All,
I've placed a Tmobile sim in my Att unlocked GS3. Ive seen many posts stating that the Att version wont get 4g on tmobile but 4g works fine for me; regularly I can get 5 to 10mb downloads. My issue though is that Im sometimes dropping from 4g to 2g/Edge then back to 4g. Should my phone be dropping to 3g instead ? Im quite shocked when it happens since I usually had strong 4g not far away at all.
Is the general consensus to to simply get a Tmobile device instead of bringing something from at&t? I really dont want to root the phone or flash roms at this point since Im just testing out the service.

You are in a refarmed market from the sound of it. The reason you go from 4g to EDGE is because the refarmed spectrum is most likely not through your entire coverage area.
T-Mobile uses the 1700 band, which at&t does not support, as their primary 4G deployment. This is why it is always recommended to get a T-Mobile S3.
That said, there is a firmware image for at&t's GS3 that unlocks T-Mobiles AWS band not just for 4G but for LTE as well. It is in the at&t forum - you will have to read the entire thread to get the relevant files and information on how to do it. Note that this CAN brick your phone permanently so only attempt it if you are willing to take that chance and you are familiar with download mode and ODIN.
The upside of using that hack is that the T-Mobile S3 doesn't support LTE at all.

Thanks for the clarification and info about the hack. Assuming I get a Tmobile device, should I expect to see a 3g icon instead or would it still say 4g?

It'll say 4g.. A 4g icon really means 3g/h+ and a 4g lte icon means lte

Hi i have Galaxy s3 ATT i747 unlocked and every ROM i install give me 3G.. If i leave stock ROM it gives me 4G with know problems.. Is there any fix i can do that will give me 4G and modem i can install. Im on tmobile network
Can you see your IMEI number? I lost mine while flashing roms and the network couldn't recognize my phone, so it booted me down to 3g (but I'm on ATT).

Do your roms have the correct apn's?
I'm having connectivity challenges when trying 4.2.2 roms on Rogers w/ my i747m.
Tried most of the recommended modems on for i747m (complete modem list) http://forum.xda-developers.com/showthread.php?t=1831898
with CM10.1 and AOKP Task650.
The result, at worst little to no connectivity, at best intermittent connectivity. It doesn't seem to want to switch between towers and getting connectivity better than gprs or edge is pretty much non-existent
When I burn the rooted Rogers ROM - root66_RWC_I747MVLDLK4.tar.md5 I get good connectivity switching and 3G. I haven't seen LTE yet but it was only officially rolled out here 9 days ago so it's still crap and only partially out.
I'm about to roll back to the rooted ROM and apply the latest Canadian patch via KIES and give up on S3 mods. If some kind canadian has the time or inclination a faq/step by step on a S3 rogers install that actually works would be very appreciated. I've tried most of the recipes on XDA, task650, cyanomodgen and can't seem to come up with a working combination that gives me data/phone service that is at least as good as stock.
thanks,
rf

This may be correct. Do other ROMs switch between 3G and H+? Do you see 4G vice 4G LTE on stock rom? What download speeds are you getting on stock and other ROMs? With AT&T, HSPA was labeled 4G instead of H or H+. They had to add LTE to the 4G after LTE went online for them in order to differentiate a difference. The majority of places have HSPA labeled as H or H+ and LTE is considered true 4G. I have noticed that many ROMs will show 3G until data is received/sent and it switches to H+.
Hey all! Ok, so my gf has had this S2 from Koodo (Telus) since January. Out of the box it came with LTE/4G enabled and working fine. However, I rarely leave things alone and right away I installed TWRP, AOKP and I think, Tiberius Kernel. Have been using variations of each since. However, ever since I did that, the 4G hasn't worked. In the phone settings it says LTE/GSM Auto. However if I change it to anything else, like LTE ONLY, for example, it just stays at LTE/GSM auto. Nothing happens. So I am wondering how to get her 4G to work again since I know it is fully capable of it and my area does have working LTE.

4g is the same as H+ on custom roms. And now some say DC. Not sure why they left behind the 4g symbol, but its all the same thing. So if you see H+, DC or 4g, its all actually 4g.
You should be on GSM/wcdma preferred in mobile settings.

I have sorta the same problem, except I have a tmobile s2 t989. I flashed cm 10.1 nightlies and the newest radio. Phone works good except my phone no longer shows the 4G symbol above the signal bars. It instead says 3G. Before rooting it said 4G above the signal bars. Every once in a while it says DC. Any advice?

Explained the symbols in posts above. And if you are getting a lot of 3g....that's reception. Your losing your 4g connection and its picking up 3g. Usually for this to happen you'd only be getting about 1 bar on your signal.

I appreciate the info. I live in Orlando and I'm pretty sure we have tmobiles 4g or hspa+. I was just wondering why I'm only getting 3G date speeds instead of 4G speeds. The internet still seems relatively fast but wanted to make sure the phone wasn't slowing down the speeds to 3G speeds.

Aosp ROMs run on 3g (umts) until data is called. Once data is called it will pull up h+(hspa+)or dc(dc-hspa) depending on your area. Its a battery saving feature and the stock Samsung ROMs show 4g all the time. Unless on edge or GPRS. I think even touchwiz ROMs went to umts while idle.
