[Q] 2.4 update broke 3g - Xperia Play Q&A, Help & Troubleshooting

I flashed 2.3.4 onto my 2.3.3 R800i and now I can no longer get 3g to work for anything other than messaging and phone calls. I've tried everything i could think of in the settings, any clue how I could fix this?

Did you put your apn settings in?

I had a problem with 3G long time ago after being abroad and using Airplane mode and/or data settings. Could not reactivate 3G for some reason and rebooting did not help but I had some on/off widget thing installed at the time and tried one of the 3G or data switches on it and it started working. Hope it helps

I spoke to a rogers agent to get the apn, thanks, wouldn't of know to do it otherwise

Right on man glad you got it worked out I went thru the same stuff when I first got my x10 it was a little frustrating but lesson learned

mine has a glitch where it switches the network it's assigned to by itself. Rogers shows up as two networks, one edge and one 3g/hspa, and I noticed if my reception is bad at a certain location it will sometimes switch to edge only, and not turn back. It's only been doing this after the update to 2.3.4
Edit/update: I figured out you can force the phone to never use edge, if you change it from wcdma preferred/gsm to only wcdma

Stuck on Edge (2g)

Today I noticed that one of my G2s was stuck on 2G and so I thought maybe I had reached my 5gb limit but then I switched SIM cards and I know it hasn't reached anywhere near the 5gb limit. I also switched SIMs and put it in another one of my G2s and I have H and 3g. I restarted the phone that has been stuck in 2G and it was still stuck I restored a rom that I had installed a few days before (H and 3G were working on it) and it was still stuck on 2G so I wiped it and reinstalled cm6.1.1 and it's still stuck in 2G.
Any ideas?
Did you make sure that you don't have use only 2G networks in the settings?

yes I did and I also use superpower but I checked it and after wiping it just remains in 2G so I don't think superpower could be doing it. I'm lost not sure what else to try I've just put Enom's new rom it and it's still stuck on Edge. While my other G2 is sitting right next to it pulling H while I tether my laptop to it while I'm at work.

Try dialing *#*#4636#*#* then go to phone info. and change the preferred network type. I think it's supposed to be on WCDMA preferred, but you could put it to WCDMA only if you want, that's how I have mine.

I just set it to that a couple of hours ago so I don't really know how it affects the battery. I thought I had it on but I guess it changed from when I tried out a Sense ROM then went back to CM.
Glad I helped.

force 3g?

.Hi guys/gals, just impoted a captivate glide from the u.s, seeing as they never released them here in the uk..
Its brand new, accept for the chap has already rooted it for me and installed cwm. Now after reading somewhere on this forum a while ago, I remember, I think, that you can only force 3g on the at&t rom and not on the rogers (which I'm running)?
Is that right? As I really need this feature, and have used it for years on my desire z runnng miui..
Are there any patches/cab files/apps that will do this for me, as I can't find a way to solve this without flashing the at&t rom..
Thanks peops..
(I also get a blank screen when activating wifi hotspot, which I use evry day also,,, this wouldn't be a common bug I spose?)
James.
As far as I know the only Rom that lets you switch to 2G (I think is what you want) is the ROMS from Rogers. You can use either the stock 2.35 or the OSIMOOD which is also based on stock just has the Bloat removed. Unfortunately all ICS roms are based on AT&T. I don't know what the JB ROms can do as I have not tried them.
Get pimp my rom. You have to get the hidden menu up, and change to GSM only. The radio has to be turned off and back on for it to work.

Hi, thanks for the replys, but its actually the other way round, I dont want it to keep dropping back to 2g, I need it to stay on 3g only..
Any suggestions?
Thanks..
Pimp my rom did the trick though, thanks
Any ideas on how to fix the wifi hotspot black screen (black screen, accept the top icon bar which is still visible)?
Thanks...
Force 3G Network
You only have to dial *#2263# and you well get the network menu

So you would rather lose data connectivity altogether than use 2G?
And if you're overseas, why do you have T-Mobile set as your provider?

Hi, bit late replying, but, I use the phone as a router via wifi tethering at home, so I want it to stay on 3g. Forceing it to stay on 3g stops it unnessaserily dropping back to 2g and slowing the connection down, it works well and I've always used this on my desire z via miui roms.
My provider is T-mobile.. T-mobile uk
Also, anyone got wifi calling working on this phone? On any rom? As I can't find any info on it.. as tmobile has free wifi calling over here..
Thanks guys..
am I the only person in the uk to use one of these? (If I am ill feel a bit special lol)

Fixed service dropping and locked LTE

I finally got LTE locked on with Telus other users confirmed Rogers, AT&T and Bell(thanks) . No service disconnections, even while on wifi.
The problem I see is conflicting settings while flashing roms/modems. This seems to be the only fix. I'm pretty stoked I figured this out because I was about to switch back to my s2x out of frustration.
This took a lot of trial and error, literally had nothing to go on and no where in particular to start. Enjoy.
MAKE SURE YOU ENABLE LTE TOGGLE IN ROM AND HAVE IT ON BEFORE STARTING.
1. Network mode(settings/wireless & networks, more/ mobile networks/ network mode) set to gsm/lte/wcdma
2.Phone setting in test mode *#*#4636#*#* set to lte/gsm
at&t / rogers should select gsm/lte/cdma in test mode
3.Recovery flash latest modem mumLL1
(at&t users flash ucdlk3)
Wipe cache/dalvik
4 . Reset. Give it a couple mins to ask the network for lte.
If you disable Lte(through toggle) and want to use 3g/H+ for battery saving, the only way I've been able to reconnect to it; is to re enable(toggle) and reset, wait a couple mins to connect.
Side note: depending on your 4g service area, it may bounce around 3g/H+ which is normal.
When you place a call it will drop to 3g (the believed reason for this is that the phone knows you won't need heavy data so falls back to ease up on the battery during calls) but will reconnect a couple mins later. Our phones are slow to negotiate Lte connections with the radio testing sockets and network stability before committing, so be patient.
Let me know if this works for you and which network. Thanks.

Re: Fixed service droping and locked LTE
To check if it worked. Go into test mode and it should say Lte in network type.

So does this mean we get no 3g?
Sent from my Mind using Telekinesis!
Yes everything works. I can unselect lte in my toggles and it drops to 3g/hspa. When I re-enabled lte I noticed that I have to make sure in network settings lte/gsm/wdcma is selected and reset phone.

O wow lucky u I can't unselect on Att lol
Sent from my Mind using Telekinesis!
Which rom are you on? Should be up in your toggles. Basically it changes you network settings from cdma/gsm to lte/gsm/cdma. But it conflicts sometimes.

Its there it just doesn't do anything because all the modems on the Att S3 are Rill locked or something so we don't have the option to do it so easily

Ok sounds promising but unable to get my ATT phone running ROM cyanogenmod10.1 03/04 nightly into Test Mode using the keypad code provided. This does work for stock ROM phones. Do you know any other way to get into the test mode?
Haven't tried stock. Im on cm10..

I'm on CM10.1 not stock.

Yeah I'm pretty sure everyone is using cm10 or aokp. Not sure if stock is having these problems. If they were I'd be on the phone yelling at Telus.
Xda I747
So let me get this right. This fixes the signal jumping around on cm10/aokp ROMs?? That's the only reason I stay on a stock based rom. I'm tired of seeing my signal jump back and fourth from 4g to 3g etc. On stock I always have a rock solid signal. It does not jump around..... Thanks in advance...
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
Yes for me and others didn't even get 4g, also it would completely go out of service. Now I get steady 4g.
Xda I747
Any alternative way to get into "test mode" other than using the keypad?
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
Sorry man, I tried looking around for a way. Could be the rom you're on. I know Liquid and Carbon are fine. Probably a couple more that I don't even know of, others have success with.

stock lies to and shows 4G all the time, cm10 and show the truth. the s3 sets at 3g until data is needed then transfers to 4g

LTE Connection Possible Fix

I have noticed that there are people starting to notice that that have LTE in their frequenting areas, but it's messing with their data once they leave these areas.
For me it was having issues kicking back to edge and even 4G signals would not pull any data, would simply say that I had no connection. Didn't matter whether rooted or not or which rom I was using.
Anyway,
I have discovered somewhat a fix for this issue.
Under Connections tab in Settings, click more networks, then mobile networks, then Access Point Names my Access Point Name was epc.tmobile.com.
I noticed in other forums their APN should be fast.t-mobile.com so I thought I'd give it a try and incredibly my results were pretty good. It goes in and out of LTE areas pretty smoothly in comparison to losing data altogether.
Give it a try and report back.
Thanks
I was experiencing drop of data connection for long period of time (at least 5-10 mins) every time I leave the house, losing my wifi connection. More than once it just won't connect at all for a good couple of hours. I just did a test today, messing with the APN, network operator settings and get it to connect to 4gLTE. Once and turn on and then off the wifi, I lose the data again. And it wasn't gonna come back.
The fast.t-mobile.com address seems to do the trick and I'm now immediately on 4gLTE after losing wifi. and the speed is AMAZING at 24,000kbps download and over 10,000kbps upload.
Thanks!!!
I already had that APN setting but I wasn't getting ant 4G LTE :/ must not be in my area yet. I'm in north Georgia

With thr default (epc..) APN, I had LTE before in NYC, DC, Boston. It just happened that the connection drop was getting more and more noticeable so I had to do something about it.

great find, I must have switched between 5-7 different roms trying to figure out why I'd lose data for up to 20min. after coming off wifi. Once I got reconnected to 4g I was afraid to even turn my wifi back on.
This seems to me to have just started recently, I'll have 4G but I might use the elevator at work and lose my connection, upon being back in service I'll be stuck on Edge for about 10-20 minutes before it picks up the 4G connection again.
I've been switching to Airplane Mode then back and that seemed to help but it doesn't any longer.
My APN is already fast.t-mobile.com, is there any other solution to fixing this?
EDIT: If I reboot my phone it connects to 4G immediately, and I'm using a Rooted Stock MDL Build w/ the Faux kernel.
Thank you!

I been having this issue since I loaded up wicked rom on my phone. Works for 5 minutes only then loose connection, the only way seem to get connected again is through making a phone call to any... I just call my voicemail to get connected again so I don't have to annoy people! Help!!!

The current modem seems to *really* want to be on LTE. If you don't care about LTE you can disable it...settings - connections tab - more networks - mobile networks - change "Network Mode" to GSM/WCDMA. You'll still get HSPA+ speeds, but it should stay connected better.

Thanks man, it's just weird that the only way to get back connected is to make a phone call... I was at the time bike store yesterday and they mentioned something about updating the towers to LTE and should be over end of this summer... They said they are already ahead of sprint as in service at the moment and they are trying to be on the same page as AT&T and Verizon. I messed with the option by the way many times but didn't notice the difference yet but I will update the result on a following reply in the future. Thanks again
