no 3g on epic after rooting - Android Software/Hacking General [Developers Only]

Ok i rooted my samsung epic 4g using clockworkmod using the syndicatedfrozen rom version 1.2 and it works great and im really pleased with it, but up in the right hand corner next to the signal bars it says 1X connection instead of 3g, did i do something wrong or not add something along with flashing the rom, because i know i am in a 3g coverage area because before i rooted i always had 3g service any help would be greatly appreciated
thanks sethman88

[Q] Locking Phone to WCDMA

I am having an issue locking the phone to WCDMA. I live an area where the EDGE signal is stronger and it constantly drops 3G. After rooting the phone, I locked it into WCDMA and it would stick all the time, even dropping all signal when I moved into an area with only GSM coverage. However, somewhere along the line, I've lost the abillity to lock it in. I have tried going into the Mobile Networks settings and selecting WCDMA Only and also doing the *#*#4636#*#* and neither one will lock it into WCDMA. Anyone else having this issue or know of a workaround for this?
If ur in a edge based area where 3g is minimal,then setting to wcdma is the worst way to go. Wcdma will lock u into 3g/4g signals ONLY! So if your in edge area only,wcdma will not give u data or signal due to the fact the phone is searching for 3g/4g signals only. And GSM or cdma is a different ball park. Set to wcdma preferred and let it pick up what it can. If a 3g or "4g" signal is avaliable,it will automatically detect it and connect.

Its not that I don't have 3G in my area, its just that it only gives me 3 bars as opposed to EDGE which will give me full signal. When it's set on wcdma preferred, it will connect to 3G and after a few minutes switch over to EDGE. With my Captivate and the Inspire when I first got it and before I rooted it, I was able to lock it into only 3G. Somehow after flashing basically every rom in this forum, I can't get that setting to stick anymore.
Ok then flash the ruu of the rooted stock inspire. It is a pd98img.zip u can load and flash via bootloader. It will stay s-off and will flash updated radio and patches. Get your data fixed and GPS and then flash a rom afterwards. Attn1 has it posted in the development.

Same issue here, I called AT&T and they said it's because the cell tower closest to my office is old and supports Edge only so my phone keeps attaching to that tower even though there are other towers in range (that will give me 3 bars of 3G) which are newer.
With the stock rom, even going into the testing menu and setting "WCDMA only", it kept me on the Edge network. I rooted and flashed a custom ROM (Android Revolution) and at first it was great. At the office I could force "WCDMA only" at my desk, when I went into the middle of the building or whatever I would just have no signal (which I was ok with).
Now with the newer versions of the ROM I could no longer force "WCDMA only"... And the OP basically ignores my questions when I ask. Something that worked fine, I flashed a new version of the ROM and it stopped working...doesn't take a genius to figure out it's probably something he changed in his ROM... Not to sound unappreciative of the developers here...they do great work. Just frustrating... >_<

[Q] Can i get 4G

I have a rooted samsung Fascinate. I want to know if there is any app or anything that I can do to get it to recieve 4g from verizion. Any suggestions are greatly appreciated. I only ask because my town has 4g, but I only ever have 1-2 bars of 3g data service at any time. So if anybody knows if I can get 4g, or any way to get a better 3g signal.
Addt info: It is not any problem with my phone, most people in my town have terrible verizon 3g ever since they added 4g
nope its a radio and internal drivers thing.
No, Verizon 4G or LTE requires completely different hardware for the radio inside. The reason your service is suffering from the advent of 4G is due to Verizon converting existing 3G sites to 4G.
When this is done, 3G signal will depricate as there will be less 3G radios serving your zone.

[Q] 3G?

well everyone i rooted my Inspire 4G and recently i have been getting 3G when i should have HSPA+ right now but its switching between the H+ symbol and the 3G symbol back when it was unrooted all i had was Edge (2G) and HSPA+ so idk but i need conformation that my phone is still in prime condition please help! and thanks if you do
From the dialer, type *#*#4636#*#* and see what it shows for network type. Mine shows HSPDA which is faux g. If it shows UMTS, then you are on 3G.
The symbols are different as to which ROM you have installed. They seem to mean very little as your real connection.
Thanks guys!

[Q] Sensation cant connect to 3g

Hello all,
I recently bought the HTC sensation with tmobile service. Im having a problem with the phone connecting to 3g service. It will connect to 4g then in the same location within my house it will drop to 2g. When i have 4g the signal strength is very low around 1 bar. I understand that it would go to a lower speed when it loses the connection but shouldn't it go to 3g before going to 2g? I used to have the HD2 (screen sensor broke) and it always had a strong 3g signal so i do have 3g coverage in my area. When the phone goes down to 2g it has full bars but as you probably know 2g is practically worthless when using the internet.
I talked to tmobile and they said the recent software update fixed some connectivity issues but after installing it, i still have the same problem and now tmobile is saying they dont have any further troubleshooting ideas. So i thought i would turn the the real experts at xda. Thanks in advance for your response!
I'm not even sure if the Sensation has a 3G option?
Nope only 4g and 2g buddy. 3g does happen but no icon for it. I know stupid!!!!!

Well if you flash a euro rom you get an h for high speed and thats your 4g and a 3 thats 3 g and then an e for 2g i believe.
Sent from my HTC Sensation Z710e
I guess its really not that big of a deal. I actually turned off the 2g capability so it always gets 4g. sometimes its only 1 bar but thats much better then 5 bars of 2g. I guess if i go outside the 4g range ill have to turn it back on but hopefully they will have an update when i do.

CM9 4G HSPA+ or 3G

Hi so I was under the impression that my skyrocket didn't have a 3G ability or HSPA+ ability and only either 4G or 2G edge because when I used stock GB when I wasn't in 4G area it would go to the painfully slow edge.but after flashing a radio and CM9 I suddenly DONT get 4G and only 3G and H? What happened and how?

As for my experience I only get the following when I'm in an area that has it:
3G = HSPA
H = HSPA+
4G = LTE
Thats just based on my experience, right now I'm in an area with LTE and it comes up as 4G. Whenever I go back home down south and theres not LTE coverage I get 3G/H signals.

Actually in some ROMs that doesn't not show the right signal code. I always got the 4G in the screen even thou I am leaving in a country where theres no 4G support yet. I Know that the max connection I will get is the HSPA+

This is using CM9?
ICS Roms usually show 3G/4G/4GLTE of course some themes can also change this.

in a Samsung/AT&T based ROM, HSPA+ is shown as 4G, and real 4G has a tiny "LTE" under the 4G. This is a marketing gimmick recently started by AT&T.
I've seen my CM9 cycle through everything (E, G, 3G, H, 4G).
I don't live in a 4G area but visited one once. 3G and G usually don't work (for me), it shows 3G briefly when downgrading from H to E, G usually appears when I lose E, and then internet access completely.
E = EDGE (usually slower than 14.4k AOL from 15 years ago)
G = GPRS
On cm9 I'm in lte area with a 4g icon and getting 30+mbps down. This is certainly lte speed whether the icon denotes it or not. As stated above, the icon sets for internet speed / capability will vary rom to rom
