I've no signal anymore on my Galaxy S2. Ill do have Wifi and GPS, but can't find a provider.
So I tried to manually put in the provider information, but i doesn't remind/work.
After that I saw my IMEI number was gone and tried many things to recover it. But none worked for me
The stange thing is. That I have not flashed/factory reseted my mobile for some weeks. It suddenly happend.
I tried programs to write a IMEI number. But those programs didn't work. Maybe someone got a good working one or have other ideas?

Hey guys i got a problem.
After flashing my phone normally with Odin like usual all of a sudden data connection aint working anymore. I works fine with wifi, but not without.
It shows 3G/H signal in the status bar, and i see the upload arrow is blinking so it is sending data, but not receiving anything.
I tried googling it, tried flashing various different roms that worked before and original firmware, but nothing helps so far.
I checked the provider info in the phone, and its all correct.
Kinda lost here, hope someone has an idea how to fix it
thx in advance
nobody? i tried everything so far and dont even know why its not working anymore
It's going to be difficult to get much help here because I don.t think most developers have had time yet to get into the innards of the A501. Have you tried flashing back to the original stock ROM? You did back it up before you flashed it with a custom one right?

No nandroid backup, only titanium backup since i never had problems before.
I tried flashing all kind of original firmware now, KH1-3, even older ones, the latest. tried all custom roms that worked fine before.
Tried different sim cards, readded the APN settings etc.
Found out now that 2G is working, but as soon as i switch to 3G etc it shows the signal for that, i see upload but no download, so it basicly stops working.

(Instead of quick reply, i hit thanks first!)
Dial *#301279#. If it doesn't work, dial *#*#301279#*#*
Select 2nd option (Change HSPA revision or whatever).
Then select 3rd option (Release 6).
Restart.
Also, check your APN settings.
Use an app called Tweakker which will configure your apn if u dont know exact settings.
thanks for the quick replies guys.
so i did play with the codes today already, the option you stated i tried but sadly it didnt change anything.
HOWEVER i did choose disable HDSPA completly now, so i am on 3G only and guess what, now it works!!
Speeds are not what they used to be at this location, but that might be due to my data limit so i have to check.
With other codes i found out that while being on H/H+ phone didnt download 1 byte, so i have to wonder why.
With 3G it is working now, but what could the cause be. Used to flash quite often and it always worked, so not sure if thats even related to my problem atm.
Any idea what might cause the H stuff not working at all? I read about the SII getting stuck on H+ etc. before, but all the tricks with rebooting or toggling flight mode etc. didnt work for me
so far, thanks a lot!
Try different modems. Depending on ur location and service provider, atleast one should work right. I'm using KI3 modem without problems.

modem depending on location and provider?
i tried several modems from the original firmware thread under development. they all used to work fine before, now they dont. KI3, KI8, KH3 etc. all nothing :/
Hmm strange. May be you should delete all apns, and configure a new one for your provider.
Also give KG5 and KG2 a try.
i am having a SGS2 with KI3 and sensation rom 1.7 with kernel siyah 2.0. after doing this i am also facing a problem with my data connection. it works but its on / off.
can you suggest come remedies like now please .............
Very strange.. I've had this phone for over 4 months and I was using the latest villain rom. Everything was working great and last night out of nowhere, the phone signal bars dissapeared and went into the no parking type singh that shows up instead. I didnt think much of it, I thought it was just my carrier (telcel, in mexico) sucking for a few minutes. After a while, nothing changed, I went into airplane mode and tried to go back to regular mode but the phone got stuck in airplane mode.
I erased all data, factory reset, even went back to telcel's stock rom. Reflashhd the original kernel, etc. Nothing.. basicaly, my galaxy s2 just became a mini tablet (because wifi does work)
If I go to settings and mobile networks it tells me the sim card isnt inserted. Which is not true. I still tried to switch to a different sim card to see if that was the problem but that didnt work either.
Is this a fixable problem? Or did my phone die?
Thanks
Looks like your efs partition is messed up. Hopefully you have a backup. There are many threads on here about efs problems.

Can you see your imei?

I don't have any kind of backups for that.. what do you mean?
as for the IMEI, dialing *#06# just shows a blank pop up that says IMEI but I get no number.
Any idea if this is fixable?

Dear reader,
I got a problem with my Titan for a couple of weeks now.
A couple of times a day when I grab my Titan and want to use it -> get it out of standby, it doesn't reacts to any input/buttons etc. just nothing. No feedback from capacitive buttons. Only way is to remove battery, insert it again and boot it up. But this occurs 20 times a day. I doesn't happen all the time though. But it is very frustrating.
It started after using the DFT rom for a couple of weeks. I hard resetted it, still same problem. Then I flashed the Dynamics7 rom, still same problem. So I start to believe that it's something hardware related, or maybe the following thing;
Though some other strange thing is that every time I hard resetted my device or flashed an other rom, and then installed the Facebook app, the FB app works fine, untill the first time my phone has the above mentioned strange bug. So after I restarted my phone, the FB app crashes while starting. And never works again... (FB app version 2.7.0.0)
Anyone with the same problem or suggestions?
Any help will be appriciated.
Thanks in advance,
Lars
It seems it has something to do with my mobile network or simcard or something. when in flightmode and using wifi it hasn't happend anymore fore some time now...
Well, I ordered a new simcard, in the hope that the problem would be solved.. But it has no effect. Tried 3 different roms, DFT, Dynamics7 and currently the standerd rom. All three, same problem.
As the problem becomes more frequent the last days, it also happens while calling, or other use of the phone, and not only when the device is locked...
Anyone with some suggestions?
Have you tried not installing any apps at all? Just running fresh?
Try not syncing your hotmail account either. Just let it run as a solo phone.
Also, while you factory reset what will be worth looking into is, having data connection switched off. Only using 2G.
I have had exactly same problem with my old Nokia E63. I never got around the issue. It was one specific operator (Vectone, UK) and every other company's SIM worked without causing issues. Maybe worth testing some other network provider's SIM from your friend?

well I found the problem. It's the Facebook app (not the integrated one).
Uninstalled it, problem solved. Installed it again, problem is back.
I have sgs3 international. A few months ago my phone started having down times. By down times mean that the network connection suddenly lost. I get the no signal sign where the reception bar is. It says no service in the status bar and I cant do any network related functions such as calling, sms, recive calls and surf the web. The phone would randomly lose the connection and find it again. The down times started on short perios and get worse with time. Today my phone is mostly down and sometimes get reception. When I reboot when its down and check imei it says null/null. When it has connection the imei is normal. After short use on the phone it gors down again but the imei stays the same but goes to nnull after restart. I tried different operating systems it didnt help. Tried different methods of backing up and restoring efs, didnt help. Also I rwad a lot of no service symptoms but in none of them had the peoblem of random down and up times.
Tried anti virus and nothing was found.
Also I dont know if its relevant but at the beginning my system memory used to fill up during the down times. My hd filled up in 2 days while I didn't use the phone. I reset factory settings to clear thr hd (my system folder would grow until the entire hd was full). After formatting and installing different os. Today only the down time persists and it only get worse.
Please if you ever incountered this or have any info HELP ME!!!
Can anyone please help. I cant dolve this on my own. Am I the only one this happend to? If I have an invalid .nv_data or some other filebwrong in my efs folder would my phone be able to reconnect to the network every once in a while? Are there viruses that block phone communication? If it is a virus what should I look for? A specific file or folder on my phone (my phone is rooted and I have rooted explorer). Has anyone encountered anything like what I describe?
Since this problem happens from time to time, and it is not permanent, I guess that your IMEI number is intact.
Have you tried a different modem?
You could also try an official update of Sammy i.e. if you use 4.1.2, you could upgrade to 4.3 through OTA maybe
the same goes to me, i have similar problem with him, pls help us! :crying:
Hi guys, I have a problem with my RN2. It was working properly two months and today network just broke and after that always says no service. When I go into mobile networks it recognizes sim card, if I go to search mobile network sometime find networks, sometime not and newer want to connect. I was trying different sim card and always show same problem. I also tried several roms without results.
Anybody knows what the problem can be?

I had the same problem like you. Phone show that service is sometimes working, sometimes not. But really iy never worked. I had to copy my IMEI from my backup and now everything works.
If you have backup, check if mobile service works on it.
Always throw this error...
Remove battery, put cable, press ok and back battery.
Also same problem, connect phone, remove battery press ok back battery.
I changed dll in system32...
