No 3G after flashing, only EDGE

Hi !!
Looking in the forums, i have seen this problem in other models
The solution, normally, is to reset the APN settings to default (haven't worked for me)
flashed to stock firmware ... still with EDGE
Someone have experienced the same problem ?

Try a factory reset

u flashed back to stockrom using odin?
i have no idea bout this problem
but if you flashed stockrom using odin and did hard reset should fix the problem.
make sure its not about a network trouble from the provider

you might try this...open setting>wireless and network>mobile network. untick use packet data. network mode, choose wcdma only. tick use packet data.

This is what i've done
1- Flashed to an Indian firmware version, no backup (my mistake). From that
moment, losed 3G/H connectivity
2- Flashed various firmwares, no success
3- Thanks to Doky, i was able to get the original firmware of my phone, installed it and change the country via *#272*_your_imei_# and reboot
4- Still with EDGE ....
In a previous flash, i used the "WCDMA Only", but i lost my mobile network .
Going to test in another phone to see if it's a provider problem .....
Thanks for your help ...

when i used "WCDMA Only", my current network changed (i'm from Colombia, my SIM is movistar, changing the setting changed the current network to Tigo) ....

based on your explanation, it seems that you have bad signal reception dude...

Try some other South American modem from the OP in my topic!
Flash only the Phone/Modem part of S5360L and S5360B packs!

There's something special with that version ? ... i'm trying to not flash my phone unless the firmware has any sort of light to solve my problem (avoiding factory reset ... my phone must be dizzy ... so many resets ... )

[Q] Packet Data and Signal not working on my one x

Hey all,
I have had my one x (running unofficial cyanogenmod 10 nightlies) for over 3 months now, but recently, my mobile data connection dropped. Now, the signal often disappears (especially when i reboot) and it takes random fiddling with settings to fix. When i do get signal, i can call and text, but am still unable to use packet data. I tried taking out the sim method and even factory reset my phone (still running cyanogenmod.) Now it wont let me connect to my google account as it says "cant find a reliable server" so i cant even restore my app with titanium backup. Is this likely to be problem with the rom? If so, should i flash another (eg viperx rom?)
Thanks for any help

Well it doesnt hurt to try a different rom ..... just do it and find out if the problem is sotware related :thumbup:

Thanks

No network signal w/ 2 sim card

Here's my problem, I'm on latest cm10.2 nightly and I don't have any network signal...I tried with 2 different sim cards, both can be read with a "Sim Card Reader" from the Playstore but I cannot send/receive sms or call with both sim cards...I tried to enter manually the APN but still nothing...the sim card tray is not broken in any kind...what's the problem? I just reinstalled the stock firmware but no chance, no signal at all...that's weird!!!
Any help or fix are welcome

I've a E975 version and last week I pick up my phone and it was with no signal, reboot and nothing happen, went to a store and my SIM card was ok and a different network SIM card was not working too. The phone was not able to "read" the PIN code (my SIM card PIN is disabled).
I've flashed the ROM again (Savyrom) and I had a subsystem crash and afterwards kernel crash's, the stock ROM backup and kdz installation have not helped either.
Now I've sent it to LG support service because after a factory reset i've lost my IMEI and the phone was rebooting 30s after starting up and I was not in a mood to try to restore the Freegee IMEI backup.
Do you have the IMEI number?

So, here's my problem now...
I just reinstall stock jb firmware on my phone, I can see the IMEI in the setting but I don't have any signal from my carrier...
I have an EFS backup but I think it's broken...Anyone can open it and verify if it's true? I can send those 3 files...

My advice is to send the phone to LG support, maybe you have a SIM card hardware problem... At least you don't have system crash's and reboots like me.
I was with IMEI too I'm almost 100% sure that a lost it after the hard reset.

Hummmm...that's not a hardware problem because the phone recognize the sim card (sim serial number, sim state is ''Ready'', sim country ISO: Ca)
I surely think it's related to the EFS partition but I got the IMEI...that's weird
And I can't send him to LG support because the warranty is over...

[Q] Does deactivating mobile data on CM 10,deactivates calls/sms as well?

I just installed the latest 10.1 CM Rom. After messing a bit with settings,i went to Data usage and deactivated Mobile Data, something that i did on Stock Firmware as well.
After that,i found out that i couldnt receive or make any calls.
On Stock firmware,deactivating mobile data was only blocking any internet connection and data usage without wifi (cant explain it better,i think u know what i mean). But calls/sms etc were still activated.
Is there a way to do that on CM 10.1?
Thanx in advance

Nope

Definitely a bug.
You can generally fit MMS under "mobile data" depending on semantics (and more rarely SMS or video calls), but surely not regular phone use...

No.. You must still be able to make calls/send SMSs if the mobile data is deactivated... Restart ur phone.. If the problem persists.. Flash the ROM again..

[Q] No Signal after Stock Flash From Odin

Ok. I was on JediX20 not to long ago. I was having problems with my signal. It had completely no signal. I put the phone into download mode and reflashed the stock firmware through odin. It works like a charm except....when I boot the phone up with no sim card...it shows signal strength...but when i put my sim card in and turn it on...it gives me a no signal icon + no mobile network when i try to dial out. I thought it was my sim card and it had gave out so i talked to my phone rep and i switched to a brand new sim card. Same thing happen. The only reason I know its a software and not a hardware issue is because when i go to settings, back up and reset, and i go through everything to reset it. The icons for data and signal appear just before it cuts off. Im at a loss of what to do. Any Advice?? or a Thread someone could point me too?

IMEI or Baseband available?

Did you flash the correct firmware ?? (have to ask )..
And once your Odin flash was complete ...did you boot into recovery and wipe all data and caches ??
It sure sounds like you're running into an incorrect APN on boot...
As mentioned above ...does your phone show the correct information ??

I didnt wipe data and cache as soon as I flashed through odin. I did after the phone booted up. Maybe ill try that. Thanks.
