4G On My Skyrocket Finally Working BUT........ - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Ok...i added the Blaze Radio Mod to my Stock 4.0.4 Firmware on my Skyrocket. All went good. I see a 4G now. BUT...theres no bars in the signal. Why is this? And when i do the speed test now...keep saying try again. Ok...just now as im typing this...i changed the WCDMA to 1700....an now the speedtest gave me 3.00 Mbps download and 0.49 upload. But only 1 bar in my signal. Any way at all to improve that? I know my bar was more then that when i had edge or my other 3G phone. Let me know something if your reading this....and thanks.
THANKS TO ALL YOU GUYS ON HERE THAT REPLIED TO MY COMMENTS TO HELP. ILL TRY TO GIVE THANKS TO ALL OF YOU. THANKS AGAIN.

so on at&t uclf6 you were not getting 4G LTE? i have had no problems... i would not recommend using the blaze radio as it just never worked as well for me. have you tried some of the other ics radios? there are a bunch floating around. good luck

No i havent. People seem to be saying Blaze's Mod one is the only or at least best one. I mean...the 4G is there.....but no signal bars. Why would that be tho?
Oh..its unlocked using T Mobile now. If that helps.

I suspect the signal meter with with blaze mod is not that accurate. I routinely get in the a high percentage under cell standby time without signal, even in areas I know I have service. These are areas I spend multiple hours at a time at making and receiving calls.

Man..i dont know. Something is funny with this. When i turn my WiFi off....the 4G comes on...no signal bars...Market take a while to load. Few apps even timed out. And i KNOW im in a good coverage area. Is the Blaze Mod radio actually the best one? Is there others to use for us thats unlocked using T Mobile?

By saying 4G do you mean LTE or HSPA+?

It just shows 4G at the top. Is there another symbol? In my settings...about phone....it says Mobile Network Type:UMTS:3. I did see HSPA earlier for a bit. Guess i still have some fiddling to do. Wonder if there is another Radio that may give me more Bars. Mine shows 1 or none. But has the 4G symbol.

on skyrocket 4G isn't actually 4G it shows it when your connected to HSPA and I think also GSM not sure about the latter.
When your connected to LTE it will show 4G LTE.
Also by choosing WCDMA your actually choosing HSPA or at least that's how it looks to me.
Try different radios before working by stuff you read people say, each phone has different hardware, everyone leaves in different areas and thus each modem works differently for different people.
Also download network signal app from the market and check your dbm which means your reception, you can't count on bars because it's programmed differently for each modem -65 dmb and lower(or higher if your a match freak) is excellent -65 to -75 is good and the close it is to -100 is the worse reception you have.

Hmmm. True. Man..im tired of swapping all these Radios. Wanna find one that works decent at least. Some people say they get 1 to no bars in the house like i do. Then go outside an get 3 Bars. Im gonna download that Signal app. Sounds very interesting. I have it on LTE in the *#2263* now. Let me try the signal thing. Thanks man.
[Edit] Love the Network Signal Info Pro. Even tho its showing a frown for my mobile. But WiFi really good. I saw some Network Signal Boosters. I mean...do those really work if anyone know? Tried 2...didnt really see anything.

Turning on HSDPA?

I've seen screenshots of Captivates homescreens from you peoples showing an H instead of just 3G. May I ask how you enabled this? Thanks in advance!

HSDPA and 3G are the same thing (i'm pretty sure)
or more technically speaking, HSDPA is one half of 3G, with HSUPA being the other half (HSDPA=download, HSUPA=upload)...
can anybody correct me if i'm wrong?
You're correct. AT&T requires all its 3G phone to display 3G instead of any other icon. Often times, ppl find ways to replace it with the native 3G icon, H, which is widely used by rest of the world. But that makes no difference in actual connection speed.

this is correct. when referring to both of them together they are commonly called just HSPA.

"3G" is the common short abbreviation for UMTS. HSDPA is an update to UMTS that gives faster download speeds (a version is widely deployed on AT&T). HSUPA is a protocol upgrade that enables faster upload speeds (installing HSUPA equipment borked upload speed on AT&T recently). Combining the two is called HSPA. HSPA+ is an update to HSPA that's even faster. T-Mobile is planning on rolling this out. LTE (AT&T's 4G pathway) is totally unrelated to HSPA.
Thanks for your replies! I appreciate the schooling

This is the correct post.
Also, I'm certain AT&T doesn't disallow the H icon because I've seen screenshots of the Captivate with that icon.
However, at the same time, I have a -51 dBm signal and no HSUPA which I know I should be able to get here because my iPhone 4 got it. Something is going on, but I'm not sure what yet.
Edit: Nevermind, it sounds like I'm wrong. In the manual there's no mention of an H icon. There's also no mention of HSUPA. I think we just got screwed by AT&T. What a surprise.

I'm pretty sure AT&T does disallow use of the H icon. They did on my Fuze. The reason is that there's ALWAYS confusion when people don't have a good operational knowledge of the protocol names. There's always someone on the EnergyROM or Cyanogenmod threads asking why "only" H comes up when they expect 3G.
Anyway, I have an AT&T band Nexus One as well as a Captivate. The N1 is definitely HSUPA compatible. I just tried speedtest.net a few times and got an average of 2.5M down and 175k up (5 runs no run over 256k) in midtown Manhattan. On my Captivate I'm getting ~4M down and 200k up. Upload speeds are about the same, probably limited by AT&T's current (under) capability.
I don't have access to an iPhone 4, but if you do, could you do a few runs on the speedtest.net app on both devices from the same location and let us know the results? At this point, I'm pretty convinced it's the HSUPA equipment screw-up at AT&T not lack of HSUPA on the phone.

That's what I was saying. My iPhone 4 got HSUPA here with no issue at all. When everyone else's HSUPA had issues, I still had no problem at all. So unless HSUPA decided to die in my area the day I returned my iPhone 4, I don't think the Captivate has it.

When did you return it? The iPhone 4 was released on June 24 and the AT&T HSUPA issue cropped up around July 6th or so. That's when my Nexus went from over ~1M up to ~200k up. If you gave it up after July 6, what sort of upload speeds were you getting? What sort of speeds are you getting now on the Captivate? Not trying to grill you or anything, I'm genuinely curious.

[Q] any way to force HSPA??

I'm f***ing tired with my connection keeps dropping back to 3g instead of H when the signal strength is strong enough and the speed as you know becomes miserably slow, very much slower! I know how to force 3g over 2g but not H. So, is there any ways to force HSDPA over 3g? Any help is appreciated
I think HSPA is based on coverage, you can't really forced it. I have no idea how HSPA worked in your country (mine is full HSPA coverage except underground though) but if you are losing HSPA easily probably means your area is lacking proper HSPA coverage. Try calling your operator and asked if there is full proper HSPA coverage in your area.
Oops. Should have explained more clearly. The area is well covered. The signal outside the house is 4/4 bars with H all the time. Inside the house is 3 bars also with H but sometimes drops to 3g. And in my room, the signal drops to 1 or 0 bars but sometimes the network is on H but most of the times is on 3g. So I need to use H all the time. How?
Well, seems like nobody cares enough about this issue(or good enough to know how to solve). but never mind. Got it all figured out. now at least I can use 3g in my room with 3 bars and not edge
What was the solution you figured out? I have the same issue...
You can change your 3g and h limits by editing your prop build using root explorer, have done it on my x10i to increase up and download speed, but dont know the settings for other phones. Try searching 3g+ on xda for relevant thread.

Well I see some settings relating to the Category for HSUPA/HSDPA but not a way to actually control whether 3g or HSPA is selected..

stuck on 3G!

my old phone was Tattoo and it was always staying on HSPA or something like that! now on my nexus I'm always on 3G!
what can you tell me about this, or how can I fix it?
Stock Android does not distinguish between 3G and HSDPA on the status bar. You should still be getting HSDPA speeds though.
that's kinda odd! thanks for the answer...
Most people don't know the difference between Edge, 3G, or any of the HSPA variants (HSPA, HSPA+, HSDPA, HSUPA). Heck they don't even know what 4G is and couldn't tell you what on earth LTE, WiMax, or HSUPA is. Stock Android doesn't differentiate because people know what 3G means and since HSPA is still technically at the most 3.5G it is a little confusing to change the symbol. The mass population dictates the way things work and we here at XDA find ways to make it work the better way. =) Hence the reason why a good number of custom roms allow for the OS to differentiate between each individual type of data network usage.

does the g2x even have a 3g indicator icon?

ive noticed that i get a 4g and a 2g icon but wheres the 3g icon? has anyone seened it?
Travling through the middle of nowhere over the last 3 days I've seen, no signal, G, 2G, 3G, & 4G. It's there.
I also have not seen the 3G icon. I drive through the city and would think when I get out if 4G I would at least still be in a 3G area. Wonder if something may be wrong....

Same here but this is the first 4G device I have had and I know for a fact most of my city is covered by 4G. What is also weird is that in areas where I would have 1 or 2 bars with my Vibrant, it is telling me I have full bars worth of 4G with the G2X.
its there in the framwork i checked..
Im just wondering why it doesnt display 3G when its on UMTS... it sticks to 4G all the time...
very strange in the instruction manual it also shows 3g icon!

A lot of this has to do with the fact that T-Mobile's 3G towers == their 4G towers so if you're in an area where all of their towers have been upgraded to HSPA+ you will NEVER show 3G because you're always on a 4G tower. The only time you will show a 3G signal is if you're in an older area where they have pre-HSPA+ upgradeable towers. This is how T-mobile can say they have the biggest 4G network because almost all of their old HSPA/3G equipment has been turned into 4G equipment via software upgrades.
I have had my g2x for about 5 days and all I ever see is 4G or E never 3g. I have been checking in the settings/about phone/status and even when the phone is showing 3-4 bars of 4G it is still on umts. In the exact same location and within a minute or so when checking it with my Vibrant I will have 3 bars of H or 3G and in status it shows as hspda or hspda+. What is that about? I have checked this out at least 6 to 7 times a day and it is always the same only umts on the G2X and Hspda or Hspda+ on the Vibrant. I called CS and they wanted to send out another G2X I reluctantly said yes. I do really like this phone and will try to be patient but the device I have now has multiple issues. I am going to take the stance that this is an isolated case and the new one will be golden!!!

This is true. There's pretty much no need for a '3G' icon. Though, technically, it's debatable whether or not T-Mo's (or any other carriers) offerings right now are actually '4G' (according to the standards committees that define those things), but that's a different argument
tl;dr: T-Mo's 3G and 4G operate on pretty much the same technology, so if you're in an area where there was 3G, you'll probably have 4G. It doesn't need to switch back and forth or be toggled like the other solutions (looking at you Wi-Max)

T-mobile LTE N4 vs N5

I just helped my son install the hybrid modem for his Nexus 4 and set up the T-mobile APN for it. I was about to tell him that he would have to go somewhere else to test it since I never get LTE at home, and then boom, the 4G icon shows up on his phone! I checked Network Signal Info and sure enough, it's got an LTE connection with about 6Mbps transfer rate. Sitting right next to him my N5 has only 3G with occasional switches up to HSPA and back, and a very low transfer rate. What gives? I am able to get LTE on the N5 in other areas of town and it works wonderfully, but around my home it is very weak and almost never runs in LTE mode.
Could it be that the N4 is connecting on a different LTE band? If so, why is the N5 not using that band as well? Is there something that can be done for the N5 to tweak it to improve its LTE reception or how it chooses how to connect to available LTE signals?
Both N4 and N5 have 1700 band so it should get perfect HSDPA.
It might be the towers in your area are busy or the signal is weak.
I use straight talk t-mobil and I get HSDPA around 15Mbps and my friend get a little more on LTE here in chicagoland.
Also for people on Straight talk if you want to get LTE att version you need to get a new simcard and change APN and for t-mobil
just get a new simcard and boom you get LTE.
Idk if I'd worry about it. In most places the HSDPA speeds for T-Mobile are the same or better than the LTE speeds you would get. I'm in the far north chicago suburbs and I get LTE and HSDPA downloads at 25mbps. The LTE coverage is still a bit spotty. Its probably only worth it if I you're in a developed urban area. However it is a bit strange that you guys have the same hardware, service and location but different connections. The only thing I can think of is that I've seen some people instruct to setup the apn as fast.tmobile.com. however mine only worked with fast.T-Mobile.com (with the dash). I would also check to confirm that your phone is set to lte preferred (LTE/gsm) and not gsm priority. Those are the only things I can think that I can think of. Hope it helps.

T-Mobile 4G LTE will properly works on fast.t-mobile.com, fast.tmobile.com is not the proper APN (the - matters)
There are just way too many variables. Maybe his modem has better reception, newer sim card, etc.

Fwiw there are other threads where people have reported that the N4 picks up LTE in the same place that an N5 does not. So you are not alone. N4 may have a stronger radio. That would be unfortunate... Never good to see a step backwards on something as important as that.

Good news everyone! I too has having this problem. My Nexus 4 was an LTE champ and then it was a huge let down that my Nexus 5 was treating LTE like it had cooties, but now my Nexus 5 works the way it should. What I did was go to my nearest T-Mobile store and told the representative what was happening. He called tech support and they ended up doing some sort of reset to my account. I also had questions about my SIM card and felt that it could have been at fault. He offered to switch it out to the new ISIS SIM and as soon as my phone booted up, it was on LTE. Since then, it has behaved like my Nexus 4. I am even in my office where the Nexus 5 wasn't picking up LTE, but my Nexus 4 was, and it is on LTE at the moment.
I am not sure if the reset that tech support did solved the problem or the new SIM, but I would definately give that a try--it didn't cost me anything and now I am happy with my Nexus 5. Good luck!
In my experience my N4 has slightly better signal pickup than my N5.
The real reason is probably differences in the radios' priority algorithms. Set your N5 to LTE-only and see what happens, I imagine you'll get LTE.

Did you not get LTE at all, or really poor LTE signal/speed?

I would get LTE eventually only to lose it when it reached 2 bars or lower. It was really weird. I would be in areas where one would get 5 bars of LTE and the phone would sit on HSPA until I would show the phone it was on LTE by switching to LTE Only under the secret dialer menu and then back to GSM/LTE (if you use LTE only, you will lose voice). Then it would hold LTE until it reached 1-2 bars and then go back to HSPA.
I hope this helps.
I am seeing strange readings of signal strength. I see a 10+ db difference between what is reported in the phone status and an app like rootmetrics.
I don't know which one is misrepresenting the signal strength but it seems the roometrics is more accurate because my nexus 4 the signal strength is roughly the same on lte.
Can anyone else confirm?
