Skyrocket getting tmobile 4g - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Hi, I know getting the tmobile 4g has been discussed before but im having a strange issue. I flashed cm10.1 and the umcm1 radio and successfully got excellent 4g in two different cities. Well I jusy moved somewhere new and it no longer gets 4g. A friend on tmobile with a htc sensation 4g gets the 4g no problem while I was getting edge. So I tried flashing numerous radios including the ucmc1, uxuma7, uvmb1, uvmc6. On all of these I either only got edge or flashing between hspa and DC with horrible speed and lag when I tested it.
I even installed a new rom, the fresh n slim one and tried new radios for that but same issue. Ive also tried switching between the fast and epc tmobile apns with no luck. The weird thing is when I installrd freshnslim it shows the 4g icon but its still the same awful speed and lag. Im at a loss for what to try next, please help!

You tried everything you can already...Now you have 2 last chances :either ditch T-Mobile or buy a T-Mobile phone...

4g down or buggered phone?

Im in the DC area and my phone wont connect to 4g for life of me (im in a strong 4g area). tried toggling. tried forcing LTE only(either 1x shows up or nothing at all). tried turning off data for 10 minutes. tried removing battery. tried full wipe (wiped three times cache, tried clearing davlik cache and battery stats...three times) reinstalling 1.7. I can still connect to 3g and 1x. Just no 4g
i was initially on bamf's 2.0b5 and noticed i couldnt get 4g. so i restored back to 1.7 and still no 4g. and no i didnt forget to flash the appropriate radios. i called verizon to see if there were issues with the network in the area and they came up with nothing. is my radio broken or am i missing something here?
Try starting the phone up once without the sim card in and then reinstall the sim card and see if it works.

just tried that. no dice. any other suggestions?
Maybe take it in to vzw and have them test the sim. It could be fried.

whoa. i didnt know that could happen.
same thing with mine I am in Manasasso area and i get 4g off and on but cant get on the market or google, then i back to 1x so is it a phone issue or a system issue.
Well with me its not even on and off. I get nothing at all.

I'm sure this is a stupid question but it must be asked. Do you have the back of the phone off?
no such thing as a dumb question. just dumb people. hahaha im kidding. just trying to make light of the situation a little at least. i had a teacher that would always joke around like that so i had to say it.
but i digress, no the battery cover is not off. like i said, 3g and 1x works. just no 4g. can it be possible that just the 4g radio could be broken or if that were the case, i wouldnt have any data network at all?......
and as i was typing this message, my 4g connection had just connected. i think it has to do with the area where i live because I am now in my work building and it seems to be working fine now...i guess verizon lied to me... thanks for the suggestions. will post if things change.
Well, according to Verizon and their coverage map I'm supposed to get 4G at my house but I don't. Granted, I am on the edge. Now, here at work is a different story...solid 4G and it never looks for 3G.
Yeah, I am supposed to have 4g at where I live too. And I would get a strong signal too, which was why I was totally stumped when i couldnt get a 4g connection all of a sudden and verizon told me there were no problems with the network in the area.
this is happening to me as well. Phone keeps jumping between 1X and 3G all the time. I rarely get 4G anymore
I'm on Perfect Storm1.5 running the MR2.5 Radio chingy leaked
I have tried 4 different radios as well as ROMs over this past week, no change on either
been 4 hours and phone hasnt dropped 4g since. even flashed back to bamf 2.0b6. I would get no signal on reboot, but toggling works like usual again. i guess where I live is having problems right now. will post when i get back.
working now. im guessing its the network. running 2.0b6 with mr2.5
This was happening to me as well. I would sometime get "4G", but it's fake 4G, as I would not be able to receive any downstream data, and connectivity would soon cut out. I've gone from GingerRemix 2.1 back -> 1.7 -> 1.63 -> stock -> stock unrooted, and could not get 4G back.
I decided to throw in the towel and go to Verizon (with GingerRemix 2.1 loaded), to compare. They definitely had 4G in store while I was carrying 3G around. I told the "device specialist", and without much questions, he popped in a new sim card for me. I had 4G then until I was about 4 steps out the door, and it would fall back to 3G. The dude and I spent the next hour swapping out another card, placing my sim card into a returned TBolt, but no luck. Finally, he did a factory reset on my phone. With no further luck, he resorted to ordering me a new one.
Still unsure what the issue is since he did give me a new SIM, and that SIM didn't work on another TBolt as well. We'll see whether the new one that comes in the mail tomorrow will fix the issue. I've since then reverted back to stock, since I need to mail my "broken" phone back to VZ, still no 4G.

No 4G since the update

I applied the update late Friday night and have not been able to get a 4G signal since. I'm normally in a strong 4G area and had not had any problems like this in the past except for the nationwide outage of course.
I've tried battery pulls, toggling LTE off and on and even did a factory reset. I then talked to tech support and they did a few things on their end that were unsuccessful. They then told me to get a new SIM card but once again, no luck.
Tech support is at a loss to explain what is going on and has escalated it to the higher level of support. It can take up to a week for them to get to a ticket so I guess I'm SOL until they take a look at it.
Anybody else having 4G problems since the update?
I haven't applied the update but have been stuck in 1X all day as well. I also pulled the battery, switched back and forth on Rev A, and toggled LTE. Nothing. Was going to revert back to a saved ROM next. My wife's phone happily receives 3G.
Did the update Friday night and 4G is as strong as ever.

My 4g is also working. What is weird is when I loaded a ROM I lost all signal. I loaded another Rom and nothing. I had to load radio file in hboot and I was back in business.
yea in such circumstances I had reflashed the radio and it works just fine, give it a shot
Received a replacement today, popped in the SIM card and am back to 4G. No idea what happened but the update is definitely to blame.
Yeah I got mess up too with the new update. Had to get a new simcard today and it work ok.
4G working just fine for me also

glad you got it worked out. I would have reflashed just the radio to try and fix it.
Having this issue as well since yesterday (7/11). Loaded Th3ory 5.0 with the newest radio to two different Tbolts (mine and a coworkers) and we're both experiencing the same issue. Flashed different versions of the radio, including the newest one again and had 4G come back for a short period of time before all service was gone again. Not sure if its an issue with Th3ory rom itself and since I cant post in that thread until I make a few more spam posts about nothing to get my post count up, I figured I'd post it here.
in Mid-town NYC where 4g has never been an issue before.
I should add that I wasn't rooted.
What happens if you're Rooted and running a custom ROM and you do a SIM Card pull? I really want to try this method, but i'm scared this will force my phone to download the new OTA update and that i'll either brick my phone or run into some serious issues.
I have had trouble for the last two days getting 4G, never had a problem before.
Orange County, CA area.

don't think anyone else is having problems. Might be network issues in your area. Just flashed gingertheory 5.0 yesterday with the new stock 2.0 radio from the update and no problems.
I am having the same issues 4g is gone and only stuck on 1x
Make sure you check your sim and battery cover.

You dont need to pull out the sim card, pulling the battery is good enough. All it does is update the PRL.

I'm in the same boat.... I used to get 3-4 bars of 4G service at my home, now after the update I barely get 1 bar of 3G service. I have to force the phone to lock onto 4G by choosing LTE only.

[Q] 3g/4g Switching Bug? Post here

OK, so I'm trying to round up all of those who are experiencing the 3g/4g radio switching bug. In a nutshell, it's this:
In the middle of a data-intensive process, the radio will switch several times from 3g to 4g to 3g to 4g, and over and over again. Often, it will cause disconnects, failed downloads, and interrupted streaming audio, etc.
If you are experiencing this bug, please post in this thread, and be sure to include whether you have the US or EU version of the phone. I want to consolidate all those with the problem into a large thread, so it can get more visibility.
Hi,
I have exactly the same problem with my One S.
When the phone idle, the connection is 3G but when i use the data, it switch to 4G/3G/4G/etc...
As you said, it cause disconnects and and sometimes resolving errors.
My phone :
HTC One S 1.53.401.2 (stock rom)
Kernel : 3.0.8-01050-ge2a40ab
Baseband : 0.15.31501S.19_10.12.31501S.06L
Build : 1.53.401.2.CL47230
Operator : Free (France)
Same problem, with a SH23 EU phone and firmware version 1.53.401.2.
It switches from 3G and H (which is more 3.5G or 3G+ than 4G here), but I didn't experienced connexions problems (but haven't had many opportunities till now)
EDIT: Sorry, didn't see that another thread already exists in General forum.
same issue here, same firmware

I'm with the same phone and same behavior exactly.
I've already notified HTC about t a week or more ago.
I believe this is due to EU software. My reasoning is this:
On my T-MOUS One S, everything is fine on stock firmware with root. I NEVER experience this problem, the only switching I ever get is when I'm on a fringe area with NO 3/3.5G. As soon as I flash a rom that is based on EU firmware (all of them basically), I can't run speedtests without data being interrupted and the status bar shows switching from H to 3G repeatedly. No, this is not a scientific test by any means, but once again I have no problems whatsoever on my T-Mobile US stock rom.
T mobile does have the bug
It is because the T Mobile base is programmed to not switch from 4g but I assure you I own the phone and if you do speed test you will see this bug is definitely present..
I've been doing speedtests since I bought the phone.. it never happens on mine
whether you like it or not..
Guess you have the magic device that does not have the bug which everyone else has..even though tmobile acknowledged the issue already as well as the people with the EU version which also has the bug..

[Q] Nexus S 4G - DATA DROPS

I have been having this problem with both of my Nexus S 4G ever since I got them 2 months ago.
My data drops out frequently and takes a while to get back up. If I have 4G enabled, then I have to manually reconnect it as it will not do it on it's own. This happens inside AND outside. Driving down the road or just standing in one spot.
I've tried all of the radios (basebands) and about 7 different ROMs and versions.
I've refreshed the data profile, PRL, and even tried the roaming Verizon PRL and Hybrid PRL.
Gone back to stock and tried everything from scratch. Still the same problem.
Dallas/Fort Worth Area
Network: Sprint
Baseband: D720SPRKE1
PRL Version: P:40447
I contacted Sprint and they just told me to update the profile & PRL.....
Any suggestions?
I'm not familiar with the CDMA nexus s, but are you able to change APN's? At one point I'd be able to connect to 3g (I have an I9020A), but every minute or so it would drop, so I fixed up the APN's for my carrier.
iv had a few data issues
forcing PRL and account updates has fixed it a couple of times
i'v bought used phones that iv had
to have sprint force update
im on LC1
[altho i cant tell any significant difference here]
and my prl is 61086
[a business account]
im currently on slim
make sure your mobile network
is set to roam
is not set to home only
Am I the only one with this problem? As I'm typing this I lost data but still had 3 bars. I never drop calls but only data.
Help please. This is driving me nuts.

no
i go thru periods of it acting bizarre
try disabling wifi and reboot
this USUALLY fixes mine till wifi is re-enabled
and i drop the sprint connection a few times
riding around
it then fails to re-acquire the IP address.
look in your status and see if you still have an IP
when your data fails
fwiw
I never use Wi-Fi. Ever.
Happens while using both 3G and 4G.
Sent from my Nexus S 4G using xda premium
4G is worthless here...
i dont even bother with the switch
does it do the same thing if you disable 4G?
I almost always have to use 4G (if possible) since 3G speeds are slower than dial-up.
I've tried rebooting and leaving 4G off, and still the same. Even tried going back to Gingerbread.

If going back to GB doesnt help, maybe it is hardware related?

In the original post, I stated that was one of the things I've done.
have you checked to see if you have an IP address
when data fails?
mine shows "unavailable" when it's wonky
and wont re-aquire till i reboot.
i'v seen this on 2 phones
off and on including on oem 2.3.7

I have the same problems. From what I understand, its a problem with the hardware. I can confirm that's probably the case, because I've tried many different ROMs (stock, cm, etc...) and they all have the same radio issues (3g/4g and wifi)...
I have an NS4G in the DFW area and haven't seen the issues you're reporting. I'm currently on 4.0.4 with D720SPRLC1 baseband. Maybe I'm just lucky and have a good signal at work and home. It's very rare that I find an area of DFW where I don't get any data signal at all. Not sure what to suggest.
I get random drops too and i hate it. My 3g speeds are fairly good even above 1 mbps. Highest i ever got on 3g was 1.51 mbps
Mine will lose data if I'm in a coverage free area for an extended period of time, when I'm back in range 3g icon will show up just never reconnect. A reboot fixes it
Certain Areas
There are certain areas where I live that data just disappears. Although this is just a network thing I believe. It's weird though when I am driving it's like a 10 second drop and then all is good. Hope you get a solid fix!:victory:
Backup 4g Partition
REMOVED - was a bad idea.
I've actually replaced BOTH of the phones with brand new NS4Gs and they shipped with ICS.
Still the same problem.
This is driving me nuts. I was driving and trying to download Maps for the new phone from the Play Store and it took 6 tries. Kept saying RETRY.
What I've come to believe is happening is:
When 4G connects, 3G disconnects. When 4G drops (which is does frequently), 3G has to reconnect.
***Is there a way to keep 3G "on" in the background while 4G is connected?*** Maybe a way for the radio to transition back and forth?

Net10 Data problems

Recently I bought a Samsung Galaxy S2 Skyrocket from AT&T, along with a Net10 SIM card. Everything works, but the data is unreliable. At home (10 miles from Harrisburg, PA), I have a five bar signal, but the internet works on and off. Even when I have the 4G icon on my phone, the internet does not always load. I have (best) coverage in my area, too. I have searched forums, and contacted customer support, and did not find any useful help. I have tried several APN configurations, and my modem ICS is the latest as far as I know (UCLI3), unless if I have a leaked version. Should I downgrade my ICS, upgrade to the leaked ICS, or root my phone? Is there anything I can do?

I have a Samung Galaxy Proclaim from Net10 that gets up to 3 Mbps on 3G in my area, which is enough for me. It's pretty annoying when I look at my Galaxy S2 Skyrocket, and it's not loading or lagging at 200kbps.
UCLF6
I downgraded to the uclf6 modem, which sped up the data connection by a little, but not much. I'll try downgrading even more.
I have tried the two new leaks for the ICS modem, which were UCLK4 and UCLL3. Both modem versions were unstable. What I will stick to is the Telus SGH-T989D modem update, which had proven to be the most stable and beneficent results. Thank you for all of your help!
