Hello,
A friend of mine has the RAZR i and suddenly on one day his mobile data didn't work anymore for an unknown reason. Wie tried almost everything that came into my mind (reboot, take out SIM, check all the settings...).
The problem is, he doesn't want to factory reset (of course) cause he has many important data.
The phone is on stock ROM, not rooted.
Thanks in advance.
I think only ways is to root phone and edit file with apn settings.

Hm.. That's actually bad :/
Is there any possibility to find out what has caused that problem? I'm quite proficient with phones actually (rooted, unlocked bootloader and custom ROM) respectively I have experience in phone related things.
Any other ideas or help?
Do you know, if your friend has Vodafone? Mobile Data with Vodafone doesn´t work in whole Germany at the Moment.

I have also Vodafone but had no Mobile Data Problems today. I am from Germany.
But i use only GPRS + EDGE... maybee its only UMTS with Problems? Try switching to 2G.
One time i have had the same problem. My Mobile Data was broken for nothing.
I couldn´t fix it and after a few hours and some reboots it was working again.
Think that was also a problem by Vodafone...

Hi,
I have an unbranded LG Optimus 2X with Vodafone D2 in Germany!
Since I got an custom rom on the mobile I get no data connection when I'm in 3G and sometimes also in HSDPA!
I tried Fearkills, BlazingDragon and even flashed back to stock! but I still have the problem!
By stock I used this: http://forum.xda-developers.com/showthread.php?t=1035041 (the czech,germany,... version)
While getting custom rom I also flashed new baseband version so I think it's because of that! Before I got 0218 or sth like this...
Now I tried to flash the older baseband version 0315 in stock, but still the problem!!!!
Don't know what to do else, do you have similiar problem or any idea which could help?
Desperatly
You set the correct APN?
Yes, I think so, got the standard settings:
APN: web.vodafone.de
MCC:262
MNC:02
Authentication-typ: none
APN-Typ: default
Rest not set!
and the event.vodafone.de but this is only for mms, right?
Hmm, the APN is correct. Could it be related to your SIM?
Hmm, well it is the SIM of my old mobile (HTC Magic) so its 1 and a half year old...
Can I check it when I put it into another mobile and there the 3G thing works??

Try to delete all APN and then write them back again.

Thanks so far for your suggestions!
Tried to put another sim-card into the mobile phone, but same problem there!
But it was a very old card, will test tomorrow with a newer card...
I cannot delete the apns, but I just did a reset, and it seems to help!
I got a website loaded by 3G! but it also died once so far ( then the arrows get black and no conncetion again)...
Some more suggestions what it could be? at the moment I'm in stock and even updated the baseband by LG's update software( V10b to V10c, 0315 to 0405) but still get many failures that I dont have connection, although I have!
Changing SIM-Cards didn't help, the sim put into my mobile had the same problems...
I even flashed stock with nvflash, but I can't find a version where the baseband is included, someone of you knows where to get one?
use APN Backup & Restore
If you backup, delete and then restore all APNs you can delete them manually (they are not greyed out anymore)
You can also delete them all and define the one you need manually.
Could it be that there is a general problem with VF Germany?
I also have a VF Sim and my Optimus often loses the network connection.
It only connects again when I power it off and on again. Otherwise I have no phone or data connection. Very annoying.
I have a new hint!
when im calling *#*#4636#*#* and get to mobile info(sry have different language) and then deactivate network and then want to change the network mode from for example gsm only to doesnt matter what there stands unknown and cant change it anymore! This doesnt work as supposed to be right?
After that i have no connection at all cannot connect anymore and must restart to have anything again!
I hope this helps for some pros to help me fixing it...

Hello,
I couldn't find a thread for this issue, so here it goes:
I was successfully able to install nAa kernel + MiniCM7 2.1.9 and all is working excellent, except for the 3g/2g/edge network... Is there something I should install or configure?
Sorry for my english, I'm from Argentina. My provider is Movistar.
Thanks!

Most unusual coincidence! I'm replying you on the same ROM - using the same device. Except I'm on 3G. The issue may be with your provider. Switch to 3G only and let's know the results.
Thanks for the reply!
I've tried GSM/WCDMA, WCDMA only, GSM only, etc... All the same... It doesn't work.
I've also tried the "only 2G" check... Nothing.
Let's hope somebody can help us...
Let me get this straight: Is it a 3G problem? Or is it an outright connectivity problem. "WCDMA only" works just fine for me. A Dalvik cache wipe sometimes is all you need. But let that be your final resort (after a nandroid backup). Cheers.

Uh, I can use the line for calling or messaging, if that's the question... The problem seems to be with data transfer(?). The navigator keeps saying that there's no connection available, or something like that.
Do you have mobile data enabled?
Do you have the correct APN settings for your provider?
Thanks!!!

Thank you, AlphaEcho.
That was just what I needed. I feel I went from n00b to Supern00b.
I searched apn+movistar+argentina and now I'm happy.
Hello everyone! I'd like to know if any of you know why my Sony Xperia Z C6603 does not detect or does not want to connect to 4G LTE or networks above 2G-EDGE technology. It detects my home network as 2G but the rest it detects them as 4G or 3G, but because of my SIM card I can't switch to any of them of course :/ I've already flashed my phone with no positive outcome... The problem still persists. What can I possibly do?
Thank you all so much in advance for your help! Let me know if anything from my phone (like IMEI or other stuff) is needed to help fix this issue ^^

Well I did try another SIM, but from my same carrier. I tested that Sunday when I took my phone to my carrier's offices to check if the problem was theirs. They put my SIM card in another phone and it worked on the other phone, while they put a test SIM card on my phone and it didn't work :/
I'll be attempting a bootloader unlock and a complete flash using Sony's EMMA with my phone and see if that solves the issue... I'd greatly appreciate any help I can get, I really don't know what else I can do.

Bootloader unlock is not necessary to flash stock firmware.
Just download firmware ftf file and flash it using flashtool

Network mode is LTE yes, and even so, my phone should be able to connect to at least HSPA but it doesn't go through that even :/

Ok... Just flashed with EMMA. Nothing, it's still the same. I did try another SIM card that didn't have LTE capability from another carrier and it did connect through HSPA+ and 3G, but with my SIM card it detects my home network as 2G, it should be letting me connect through HSPA like with my last Sony Ericsson phone, but nothing :/
:crying::crying: Please Help there is no network on LTE OR CDMA on SM-950F/DS & same sim card is working in other phone with 4g

I rely heavily on internet, and lose my not so many marbles left when without it, I feel your pain.
From what I am seeing trying to look into your problem, you have done all that is suggested, other than a service centre visit
Hopefully someone who has suffered but resolved this will comment and share the steps for you :fingers-crossed:

waiting for your comment brother
Have you check your APN settings?
Replaced your SIM card? (It might work on other phones but not on yours either to not sitting properly or something else. So try replacing it.)
Take your sim card out and try this.
Do a factory reset and flash firmware with CSC file (not home-CSC file, backup first. )
Let phone boot without sim card first.

You're not going to get CDMA to work on the F version of the phone as far as I know you can only use GSM that's why nothing that's being suggested is working. You need to get a GSM carrier sim card.

Ok i am trying to understand something.
Your device is SM-N950F/DS.
You are in india.
The phone can't connect to 4g/Lte after the security update. 2G and wifi is ok.
Before the update 4g/lte is fine.
You tried your simcard on other phones is able to connect to 4g/lte.
Is this correct?
May i ask how did you update to the latest firmware? ota, odin or smart switch?

Hi everyone,
Couple of days ago my phone had lost connection to the cellular network on both sims. Just says no service. Tried resetting it to the factory settings and also resetting the connection but to no avail.
Tested the sim cards and both work fine in other phones.
Does anyone have any idea how to fix it?
Contacted Xiaomi but they were less than useless. Kept referring me to how to troubleshoot WIFI connectivity problems although this is not a WIFI issue.
Any help would be appreciated. Thanks.

Yes via official update. I was hoping for a quick fix but I guess will have to do the warranty return.
can you still see your IMEI number? If somehow efs partition got corrupted, you'll lose your imei and hence cannot use cellular networks.
Just claim the warranty, it's easier.
