Cant get 3G to work?

hey guys
been trying to get 3G to work, but everytime i go into the bank selection, and pressing on the 850mhz band, it says "menu not exsist" so i cannot enable 3G
anyone know wtf is going on here and how i can make 3G work?
thanks
EDIT: it worked fine up until i flashed 2.3.3, then flashed back to darky now i cant

Is the phone actually the 850 or 900mhz version?
If it's the 850 then check to see if you have a compatible modem. May just need to flash one to fix it.
Also check if your apn settings are correct just in case.

Its a 850 version, been using it for ages but it stuffed up when i flashed to 2.3.3 then back to darky
tried flashing JG4 and JL2 which are 850 modems but still not working
and yep, they are right

Check your apn settings. You may have list them during the flash 2.3.3 flash process. I've added a link in my first post just in case you need it.

that makes 2 of us then haha!
i got no idea what happen

These are some of the things I would try in your situation:
-Restore cwm backup of rom that had working 3g (I assume you would have done that already if you had one).
-restore to factory settings.
-flash a fresh / compatible stock rom just to see if it comes back. Then re-flash darkys.
I doubt there is a problem with the phone itself. Just some software mismatch somewhere.

Ok
I just flashed the stock telstra ROM back onto the phone, and still getting 2g, and 3g is there but not going to work...
my other phone is working on 3g fine though so its not telstra
( talking about NextG here to, same thing really )
EDIT: now it says its running on the 850 band under band selection, its the only one ticked. but its still E which is 2g
under service mode, its running GSM900, ****ty 2G
would it be because my phone only has 10% battery?

Well I hope for your sake low battery is the problem.
Hey, I thought I was the only one who flashes roms with such low battery. Guess not!

i dont think your supposed to flash roms with low battery but lol

Got another idea. Since you have 'E' showing then you must have correct apn details.
So now go to mobile network settings and select only wcdma in network mode. That is 3g only. Take it off auto.
Could just be that 3g there but its defaulting to 2g due to low reception.

So they say but I've lost count of how many times I've done so at 10% or less. Never had a problem.

stupid thing says "menu not exsist" when i go into the band selection

Also
There was this walkthrough thing I saw on here ages ago, about changing the product code the manual way, But can't find it.
It had something to do with using adb to copy over something in the efs folder, can't remember
Do you know what I'm talking about?
Is it possible that when they replaced the PCB in my phone, they did not put a 850 enabled version in there? Cause nothing I do is working.....

Yep, I know what you are talking about but I use another method.
In dialler type *#272*imei# with imei being your imei number of course.
It will show you the available product codes. Just remember that once you change it the phone will automatically reboot and do a factory reset.
Not sure however if this will help with your problem.
Was 3g working after you got it back from warranty?

Yeah I tried that way but it did not work.
And I'm 99% sure it was.
They replaced it with a regular one, I put my Optus sim in there, and 3G works. So they replaced it with a Regular 900MHz version, not a NextG version
You have got to be ****ing joking....

Oohh! That hurts man! I'd be pretty pissed too. If it shows as 900 then they fu**ed up.
I'd be going to see them Asap. Problem is you'll be without a phone again until fixed.
Give them an ear-full man.

1, I assume you have good phone signal.maybe internet signal.weak.in your area?
2. Try another sim maybe smart or globe?

im have good phone signal but no 3g or edge. ill try out other networks.
Sent from my GT-P1000 using XDA App

i tried using globe. 3g/edge works fine but with sun its not working. i think my apn is wrong but i alrwady tried every apn setting for sun that i found on google but still no signal. i doubt that it has something to do with no signal in my place becuase no matter where i am its the same still no signal.

Obviously if globe works then nothing to do with the tab ;-)

Same here too with overcome kratos. I had signal until (I guess) yesterday, but now...only wi-fi. I don't know what happened. No new prog or anything else. I tried restart (twice), set the APN again, change SIM... :-( but nothing...

I just got my Nexus7 3G in Chile (bought in US).
everything was working fine but after install the Micro SIM (a standard sim, chopped according to mobile company people instructions), the tablet doesn't get data transfer (already purchased a data pack).
on google's support site for nexus, the only solution was "contact AT&T support" but that's for a AT&T user, and here I'm trying to another company (CLARO).
No info on XDA-dev's forum about this issue.
please, some help here...

Do you get a no Sim error or just no signal? Did you input your carriers APN settings into the APN list through settings?

If its compatible with your carrier then its gotta be an APN discrepancy. What APN settings are you using?

[Q] wifi problem after update to jellybean 4.1.2

hey guys.
i got the new update of jellybean and i have a wifi issue now. It's stuck on obtaining ip address and after one minute of searching it says that the signal is to low to connect even tho i'm in the same room.
I've tried fixing the issue by resetting my wifi with no luck, even factory resting my phone with no luck either. I haven't put a new rom or changed any features on the phone.
please help.
phone info
make: samsung galaxy s3 4g
network: telstra
model: gt-i9305t
android version: 4.1.2

Im having same issue currently trying to get my handset replaced by three!! Im guessing its a common problem
Sent from my GT-I9305 using xda premium

I`ve had this problem with my phone from day one. Samsung have allegedly repaired it three times and Orange once. On the third attempt by Samsung they said they can`t replicate the problem.
I`ve had this problem on 4.1.1. Upgrading to 4.1.2 didn`t help

Try changing the WiFi region code in the advanced WiFi section

Try to forget it, then try again.

Try these tips
Wifi settings
open your box/modem 192.168.1.1 or 192.168.0.1 on your PC web browser
unable "automatic frequency or channel" on your wifi setting or try to change channel
check also if your Mac adress filter is enable. disable it
Wifi congestion by channel
Wipe Cache
Forget you network
cut the wifi
reboot your phone in Recovery Mode
wipe cache partition
Reboot
lauch wifi and connect to your network

Use the search!
And read this: http://forum.xda-developers.com/showpost.php?p=36414076&postcount=31

I have a different issue with the wifi, it connects and reconnects several times in its own, did not have this problem before.

Try to flash a custom kernel like perseus <3

wifi problems after update to 4.1.2
Hi,
I found that saved profiles are randomly disabled and can be enabled using the following app "Wifi Profile manager". The app "Wifi Fixer" allows for monitering, reconnecting and logging the state of your Wifi connection. After seeing this I send an email to Samsung Netherlands. (that was today). Another work arround is to forget the network, reboot the device and try again. When searching the internet I also found this not to be device related. Many more devices have this problem after the recent update.
regards,
Robert

V30B v.s. V28B Network switch ability

I am curious if anyone knows or has posted a guide on whether or not you can somehow unlock network preferences on AT&T builds. Specifically on V28B you can choose gsm/wcdma (2g/3g) or 3g only or 2g only. V30B however does not have these options...nor did V20P. I think it has something to do with the debranded ability to connect to the Maritime network but I'm clueless really on this one. Im currently running xbsall's VX3D and I love it because its based on V30B and I have my 4g signal (even though there's no such thing as 4g where I am lol). I have a lot of network problems like dropped calls and sms fails in my house where I live so I always use the 2g only option here. Just don't want to get rid of this Rom so I thought Id ask first before flashing back to 28B.
