You could try flashing a new modem through Odin. Some work better than others. If you do a quick search of the forum you'll find loads of info.

Delay in receiving texts

I am finding that I am getting texts which were sent couple of days ago.having said that, I am not certain that this is not the case before I rooted & apply lag fix to my galaxy s? Is anyone else experiencing the same problem?

That has to do with your Sim and your provider... had that same issue with a dumb phone at one time.
Thanks for your reply, but I don't think it's anything to do with my sim/provider as my brother has an unrooted galaxy s as well rough on the same network & he has no such problem.he also has the same jf5 firmware.

You can't tell, your telco sms server may be screw up and hold your particular sms, just like email. Did that happen all the time or once a blue moon?

It happens randomly but more often recently than ever. All my family members who have cellphones are on the same cell phone provider but none of them are experiencing the same problem, I am therefore convinced it's to do with my phone somehow...

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.

[Q] cant get 3g/edge signal on my tab. need help.

anyone from the phillipines? also on sun cellular network?
need help. i cant get 3g or edge signal on my tab. i did everything. i setup apn turn on packet data and even try reboot after setup but still cant get 3g or edge signal.
im running overcome kratos.
pls help me.
thanks.

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...

Does rom region matter?

My Optimus Black cames with v20j (Canada) and I understand that there's differences between regions like apps. But other than that, is there any real difference? I've used Spain's, Germany's, Europe's and the Philippines' roms and they all run the same.

From my own experience with canadian carrier "telus or koodo".
Some of the roms seem to not get a good connection to the network,
I went as far a sending my phone for repair, rerooted my device and reflashed but kept getting cant connect to network at this time. I do beleive some one else on telus had the same issue. Can' t recal his name
Sent from my LG-P970 using xda app
Huh, I'm on Koodo and I've had no trouble with signal on any rom. I did find that some roms don't say I'm on Koodo, but Telus. But, Koodo is part of Telus so it makes sense.

Telus
I'm with Telus and since I changed my original rom from a custom one I can't get phone signal outside of town.
It's because we have the lg p970g not lg p970. We have different phone signal for our roms this is why our phone are having signal issues.
I didn't find a way to correct this problem. But is there a flashable zip for a canadian rom becaus my usb port is broken and i can only charge my cellphone and change my rom with a flashable zip file.
hope we'll find a solution someday :S
Yes for xample you cant find persian language in v20n or j but v20b have persian

i had issues when outside of town. i recently tried the n version of Zeus on the same trip and signal seemed to be better, specifically in a spot where I had no signal before. still not as strong as stock though. running telus.

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.
