[Q] No 3G connection

I recently flashed Darkyy's Gingerbread v8 and I cannot receive a 3G connection.
I have selected and unselected the "use packet data" and "data roaming" options as well as downloaded an app to turn on data connections incase it was needed, however still no luck.
I have WiFi connection, signal for messaging and calls.
Any help appreciated as I cannot find anything anywhere
SGS l9000

I would ask the rom developer .

Thanks, I've already sent a message
Do you know if it's safe to do a factory reset? Will this just take me back to 2.1 eclair?

It will not reset to ur stock firmware it will just delete all apps and settings. Did u check if u have any entries under settings/wireless settings/mobile network/access point names/ ? If not u should go on ur carriers page and resend the mms / internet settings.

did you create the APN entry in Wireless settings?

Shrooms and Allgamer - No I havent got anything under APN.
How do I go about that?
(currently searching google - for some info)
I managed to find from my providers website the details for the "Internet" APN my 3G is working thanks for your help.
My WiFi is broke now though. Im presuming this is something to do with settings as well, if anyone knows why this is happening.
I am connected to the network I just have no data coming through.
Thanks

1. NEVER DO A FACTORY RESET AFTER INSTALLING A CUSTOM ROM! - Doing a factory reset will unroot your phone leaving a ROM/files installed on your phone that would only survive if the phone was rooted sometimes causing major issues.
2. Check to make sure you still have your IMEI. Use SGS toolbox (free) From the market. If you don't then use search on xda as there is a fix
3. It might be a modem issue. Try another modem from here http://forum.xda-developers.com/showpost.php?p=9724862&postcount=14434 *If you are a bell, fido customer* or use a carrier that runs the 850 band then you should try to follow the instructions I have posted here http://forum.xda-developers.com/showpost.php?p=10533852&postcount=2525
Let me know how you go

Sorry I've just fixed it, I remembered I installed and APP called DroidWall and I never selected it to use WiFi...Sorry my fault.
Thaks everyone for your help, learned alot about my phone.

[Q] 3g is not working

Month àgo my 3g used to be working, sudenly my 3g change to 2g.
I checked my settings and everything was fine.
I putt my sim in another phone and the 3g worked, so its not a sim problem.
My apn setting are good.
I tried everything and nothing solved the problem.
What can it be?

Check Settings - Wireless and Network - Mobile Networks - Network mode, it should NOT be GSM only. Try setting it to WCDMA only.

.
I already tried it. If i putt it on wcdma only i dont get any connection.

Backup data and then factory reset .

How do i do factory reset?

Backup your data and apps using a program like Titanium Backup, then go to Clockwork Recovery and select Factory Reset/Wipe (or something similar).

I did wipe and change my rom few times and its doesnt work.

Dont know what rom you are using but i would try installing stock froyo via Odin .

It is active.

Have you tried flashing a new modem at all???
Sent from my GT-I9000 using XDA Premium App

Not yet. I dont know what kind of modem to flash.

If its your standard Galaxy S I9000 you should be able to flash any of the standard modems. I use JPY because it seems to have the best signal and battery life. If you search the forums a little you should find out how. Darkyys ROM uses it as standard

I have the same problem and I just repartitioned in Odin to JS7 and it still won't automatically go to 3G/HSDPA, I have to force it either through setting it to WCDMA only and then back to auto or through SGStools by setting it to WCDMA 1900 only and then add the others in combination bands. All of the APN settings are correct, my IMEI is still the same, my HSPA revision is set, phone information states WCDMA preferred, I've factory reset, cleared cache, cleared Dalvik cache, and as I mentioned earlier, flashed with repartition, and after all of that... I still have to force HSDPA access.

Network Error after 2.1 unbranded flashed

Hi all, well, here is my problem.
I have my stock rom 2.1 eclair from Personal, Argentina, and i flash the phone to put the 2.1 ARO (Unbranded). After the flash, the phone works great for a while, then i lost connection, and i coulnt connect to my network anymore. I couldnt performs calls, sms, or whatever related with communication. I only have wifi.
If i access to Mobile Networks -> Net Operators, the phone keeps searching and never retrieve the list of network operators. My apn list is empty, and i couldnt add new ones, mannually or by APN Restore & Backup software. The network mode is not selected, but if i choose one mode, it doesnt selected it.
I Flashed the phone with Odin, with and without repartition, but it still having errors.
Any one can help me?

Factory reset first .
jje

i've performed a factory reste, but nothing happends...

try to deactivate the mobile data and restarting the phone this worked once for me, if that doesnt work i would suggest trying another rom this also worked once for me. And if all else fails then your gonna have to send it back for repair, i had to do that last time this happened. I put on the 2.2 update from my carrier and told them that the phone messed up after updating.

The endless searching for a carrier is normal, but you should be able to enter apns manually. Search for the code to check IMEI and confirm you have one listed.
If you have a backup of your efs file, you can restore that and see if it solves the problem, or load an Argentinian csc file (they may have one in the ROM Kitchen that you can cook as an update.zip) .

gingerbread att tab

Just flashed the new gingerbread rom. Works great but it doenst recognize my sim card or network. I have att tab. Any help to restore it?

Did you remember to download the Modem package too? That's what I'm guessing.
sent from my Galaxy Tab using Cerebral up-link

Did you flash the version with the bootloader? Any whiteline issue on boot?

No I didn't download or flash a modem do I need to? I flashed the one with the bootloader. No whiteline I noticed.

I flashed with bootloader, tried 2 different modems, and no network. wifi works. tried flashing back to stock and everything went crazy. While I was using Odin, I STUPIDLY, plugged in my Captivate to charge without thinking, causing Odin to fail and I got the "phone - ! - PC" Icon.......talked about scared! Ended up using Roto's ATT stock image and Odin to get it back running again,barely. Now I get CRAZY lines when I boot (like if you tweaked the cable to an LCD screen), can't see Recovery screen....total craziness. Still no data. so I flashed back to OverCome Gingerbread ROM following his instructions, still no data
UNTIL
I swapped the SIM card with my phone. I suddenly got data on my Tab, but data would not function on my phone. Seems like the problem follows my SIM. Background: I also had a weird issue before hand where I couldn't open the Market on Cellular data without killing the data connection on Stock Rooted.
Thought I'd share.
EDIT: oh, and I can send text messages without issue.

Go to Settings, Wireless & Network, Mobile Networks, Access Point names and make sure you have one called Broadband (assuming you are on the ATT monthly data only plan)
If you dont, create a new APN and name it Broadband & make the APN Broadband as well. Just leave the other options and save it & select it.
I think by default it comes up with the ATT wap.cingular APN with doesnt work with the Tab Data plan.

Gingerbread 2.3.3 installed modem does not work
AT&T monthly pay as you go. What modem.bin do I load? Where can I get it. Is there any additional setup instructions?

Follow my instructions above and flash the JK3 modem fromt this thread.
http://forum.xda-developers.com/showthread.php?t=1069727

Mine keeps saying insert sim card to access. So how do I get it to recognize the sim?

Please anyone with some help? Can I store back to original att froyo and just wait for official upgrade?

Have you guys entered in your APN settings for ATT Broadband?
I am also having a strange radio issue. I am using an ATT Tab with Overcome v2.0 Beta 2 and the JK3 modem. 3G data works great until I try to access the Google Android Market. As soon as I do it drops the 3G connection and wont come back until I reboot it. If I dont go to the market or only go to the market on WiFi it works just fine. I also verified that the same behavior happens with the JPZ modem..
My theory is somehow ATT is blocking Gingerbread Tabs from going to the market using their SIM card. Therefore I think maybe I need to edit my build.prop to spoof them. Can anyone recommend which values should be changed? Can anyone think of anything else that could cause this? Can anyone reproduce this issue on their ATT tab?

You used the bootloader patch app, right?
Reinstall the stock 2.3, then the root, then overcome. Follow the overcome guide, this time put the modem.bin in the phone slot in odin. There is no other fox for the wiggly lines. If you don't reflash everything, you can't get into recovery mode.

i cant get into the network settings as it tells me to insert a sim. I tried to flash the modem as well with no luck.

ok so I turned on my tab to play with it a bit and I had data! It was an H and seemed to work. When I restarted the tab it stopped working and said no sim again.

1) The Gingerbread rom has a modem with it that works fine on AT&T.
2) Did you leave your sim card in while flashing?

i did leave my sim in while flashing. Should I have it out? It seems the tab only recognizes the sim card every so often. Not all the time. Any way to flash the sim recognition part?

Could you please post how you flashed your att tab so I can follow it? Thanks.

Maybe your APN is wrong.
Sent from my GT-I9400 using XDA Premium

To check APN
To check APN's you go to settings and goto wireless and networks then mobile networks and then access point names and your carrier should be setup in there if its not go here to find the settings http://ausdroid.net/apns/

A little help from a noob
Well, I've gotta start somewhere. Maybe someone can help push this out from here so more can see it, but I may have a fix that could help. I've have an Evo 4g Supersonic on CM7.2 that somehow lost its 3g data connectivity. Searching searching for APN settings, numerous calls and chats to Sprint (no help), it was finally a call to HTC that helped.
From CM7, I couldn't find a way to update my PRL and Profile. Essentially, those options are "Sense" and not on CM7, so I had to find a way to get to those settings.
Basically, I flashed a Stock ROM (5.07.651.1_Supersonic_Stock_Rooted_CPTB_v2.3-DEODEXED), updated PRL and Profile, then flashed back to my CM7 I backed up before I started this journey.
Works. All is well now. Hope this helps. I'll check back to answer questions if I can be of any more help.
Now, a disclaimer, I'm newish and/or limited in my understanding of how to toy with the Android system, so...as I've noted on many forums across the net, some people will push a "duh, why didn't you know that, noob" kind of approach. Well, go for it, but realize it's rare someone will get on a bike and know how to ride it. We all started somewhere. With that, please feel free to abbreviate, fix, and repost what I have here so this info gets out to the world. This is my FIRST post, so it's likely rife with mistakes. The intention is good.

well .... this is the same scenario with my GT-S5570i ...
Mobile data connection on my GT-S5570i with GB2.3.6 is working fine ...
but after upgraded to Jellyblast then MDC is not working ....
what I did was the change the CSC code ...
To change CSC code on your mobile ...
check your IMEI number by dial *#06# and write it down ...
(u can also check by go to setting > About phone > Status > IMEI )
after that dial *#272*YourIMEINumber# and you will see the multi CSC screen ... (if your ROM support multi CSC)
choose your country CSC and tap on install ....
phone will install and reboot itself ....
after that try your MDC again ....
hope that it should work ....
