Cant get 3G to work? - Galaxy S I9000 Q&A, Help & Troubleshooting

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.

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.

Missing sms

Recently my phone isn't able to receive some of the sms text, not all but some, I wiped data/cache and reinstall cm7 but the problem continues? Does anyone know what's wrong?

Do you have auto-retrieve enabled? Sounds dumb, but sometimes the most simple things go right above our heads.
Also, it would be of great help if you provided more information. What sms app you are using, carrier, modem, etc.
Just made sure that auto retrieve is on. I am on at&t And the radio band is T959tljl3. I'm using cm7 stable mod. It never happened before and it only started recently. And I'm not using any sms app Thanks for the help btw

Do you get a lot of text messages? One of our users on the Legend thread had the same issue. We suggested lowering the amount of messages from 100 to 50 before they are deleted. The user reported back that the issue was resolved after doing so. Not sure if cm works the same but worth a shot..
Yes I do, I will give it a shot, the weird thing is that it never happened before.
Thanks for the advice though

I'm not sure if your are referring to the modem, I believe baseband refers to the modem. Regardless, can anyone confirm that modem works on the captivate? I don't know why, but I think that modem is for the Vibrant.

Get on over to the "soggycashew.weebly" website for modem dance and also find which modem is best for your area via map location. I just did the dance again the other night and fixed my phone. I'm using the T959tljl3 - radio-cm7-ics-captivate-tljl3-signed.zip download/modem. Works perfect up in Ottawa.

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

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

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.

Cappy on T-Mobile problems.

So my cappy is running on T-Mobile. Its unlocked and on hellybean 4.2.2 . my phone works and SMS/MMS work. Data is not working however. I have to use WiFi. So here goes. I broke my note2 and decided until i get the $175 for insurance to replace it I'd use my cappy. So i pull the sim from the note2 and notice oh thats a micro sim. The Cappy takes the regular
Sim card.
I take my old sim card from straight talk and with a xacto knife and cut out a hole the shape of the micro sim. This it of course after about 20 minutes of studying the edges of each to make sure they are all lined up properly. Put the micro in the hole and slap a piece of tape on the back and insert it. Turn on the phone voila it reads T-Mobile.
The two problems I seem to be having are occasionally I get a notice that the network is unavailable and it'll last a few minutes then go away on its own then its good until next time. Usually 2 or 3 times a day. The other is not data connection. Anyone have any ideas?
OK so data works its just edge so really slow.

Compare the Captivate's frequency capabilities to that of T-mobile network frequencies and u will understand that Edge is what ur gonna get...unless u happen to be in an area that t-mobile has reworked there edge freq. to be 3g. --- but it sounds like u r not.

I also have a captivate on T-Mobile. My APN settings are:
Epc.t-mobile.com
MMSC: mms.msg.eng.t-mobile.com/mms/wapenc
MCC: 310
MNC: 260
APN Type: default,supl,mms
Every other setting is default or blank.
Your second option would be to flash a new modem in hopes that gives u better signal or 3G. I believe CM10 comes with an I9000 modem that is not the best... Try flashing kk4, its the newest and most common modem.
Hope that helps

I believe there is also but the only thing that the thread doesn't explain is how to flash radios and its something I've never been able to find clear instructions on and when asked I always get referred back to that sticky on.
Sent from my SGH-I897 using xda app-developers app
I know what you mean. I have intermittent luck with radios. There are two ways to get a radio flashed. One is using Odin and the other is with CWM just like installing a ROM. So my advice is to pick a radio and first try it with CWM installing from zip. If that doesn't work use Odin. Take the .bin file and install it the same way you would a kernel but under the modem field.
If you reboot and have no signal you either did it wrong or that modem is incompatible, so just find a different one, rinse and repeat.
Hope that helps

I found a post in the modems sticky about midway through that explained the same. First modem I flashed was a major improvement. I'm now getting 2.36mbps download speeds vs 0.16mbps before the new modem. Its ugjk4 for cm7/ICS. Gonna check the sound quality and if its good I'm gonna leave it.

Must've just been a bad radio for my area and phone to use with T-Mobile. I now get a 3g signal. Best speed so far was 4.76mbps. Blazing fast compared to what it was. Xda never ceases to amaze me with its members support and knowledge.

Hello,
I don't mean to hijack the thread, but I am facing a similar issue (no 3g) and have not been able to resolve in a very long time.
I have the T-mobile original Galaxy Tab. I am using it on a different network (outside the US) though. I am running Sapir-10-20121207 (Android 4.1.2).I have tried both the eurotab (firmware P100XXJK5) and the t-mobile (T849UVJJB) modem.bin. With either firmware I get a cell signal but there is no data connection at all. Neither 2g nor 3g. It just doesn't get data. I double checked the APN info with the provider and it all matches.
I also tried changing the "APN type", but regardless of what I put there, if I go out of the APN setting screen and come vack it always changes back to "default,supl".
What could be the reason for no data?
Thank you.
Try newer ROM, and make sure your IMEI is correct.

Thank you for the answer. Do you think it's the only option? I am really dreading re-setting everything up after upgrading to a newer version of the ROM. Or is there a way to upgrade while saving apps and settings?
Thank you!
