Weird Problem[solved]

I got this weird problem. I have aircel SIM card and I have been using it for more than a year. Two days back I couldn't get any signal. So I tried this SIM on another phone at the same location.. It works..full range
Then I tried an Idea SIM and even another aircel SIM on my g3 to verify whether any problem with cm7
But here also no problem... full range
Conclusion both g3 and particular Aircel SIM independently dont have problems but when put together there is some problem. Signal pops up for 3 secs and then disconnects sometimes.
Help!!!
Solution: Bought a duplicate SIM (had the same problem )and desperate to find a solution I choose my network manually rather than automatic.... and it worked what a relief ...will never know whether manually choosing the network in the old SIM would have worked but anyone who has this same issue should try choosing the network manually before buying a duplicate SIM(Rs50 down the drain )

even i had the same problem i thought it was because of cm7....

I had a similar problem (losing network without reason) and it was solved by flashing another rom. I've no idea what it came from...

ok its not problem of ROMs because I flashed
kyrillos ROM older version.. same problem
I even flashed asian ROM 2.1 still the same problem

Asian rom means which one.. first flash with eclair 2.1, than update via kies to DDJP6, than u can check with ur aircel network.. if u do this I think u wont face any prob..

thts the point may be contact of the sim is worn off...the same thing happened to me when i put my sim in the phone it didnt reconize cause my sim was old and when i put another sim of the same network it recognize tht sim was new...and both of the sims are working on others devices so try new sim..may it could solve ur problem...

even i had the same problem i thought it was because of cm7....

Did you check if both the networks use the same GSM band? There is a method to check the band, I have seen it here and done that. I just don't remember how. It could be that your phone suddenly doesn't receive signal of that band. Ask the moderator or someone how to change the band. Keep me posted too..

Issue 3G / 4G

Hi everyone,
I have a problem with my S4 i9505.
When I try to connect my phone on 3G or 4G, I have no data connection, I can't make call and nobody can call me.
In About phone > Status my network type is Unknow:0
If I force 2G only, no problem and earlier 3G/4G works well.
I try to flash stock firmware with Odin (HOME, Kernel, Recovery, Modem) but without success
My operator is Proximus (Belgium) and I'm in stock MGA.
Anybody can help me please ?

I know, it worked fine but sine 2 weeks I have this error
Can't understand why it doesn't work now...
2G / 3G / 4G depend of kernel or other ? Is it possible that somewhere there is a script (or other file like init) that cause this problem ?

Hi man. People keeps telling you to install new modem, kernel etc...but i think you have corrupted EFS folder.
I hope you backup your EFS folder before flashing ANY rom because, otherwise you will have to go to some repair shop.

Well, I don't understand a lot, but I think you could check if you didn't lost your IMEI. Go on Settings > About Device > Status and check if your IMEI still there.
If it is, I don't know what could be. You could try flash another modem or restore a backup (if you have one) with PhilZ Touch but if it isn't, that means you lost your IMEI. I remember I read about that somewhere, that there is a risk of losing IMEI when you flash a lot of ROMs.
If you have backup from your IMEI, just restore it. If you don't, I don't know what you could do, but I guess you could still do something.
One more thing: Wi-Fi works?
Like I said, I don't understand a lot, so everything I just said may be very stupid. Or not. Sorry for bad english.

Galaxy Y no service no calls nothing

Some months ago, gf's galaxy y random rebooted and get stuck in a bootloop, she was just using the phone normally, it don't have root or something. she managed to get in stock recovery and wiped data. When the phone booted it lost all signal, no making phone calls, when she tries to call the phone says something like "Not registered in network", status bar says no service, I tried my own sim and also can't make or receive calls.
Imei is fine, when type *#06#* displays the correct value. Phone was factory unlocked, model is gt5360L.
I've been reading tutorials here, and other forums, but nothing has worked, the phone is now on cm 11.
Please, give me some help, if anyone needs more info or something, ask me, people here always talk about flashing respective modem, bit how to know which files should I download?

Any one!! some help plese....... urgent

help?????......

same problem now as mine my IMEI just became 350050500009692 /01 emergency call only why???

some nice paper weights at least lol none of you have efs back up ? tried restoring it if you do common rule with samsungs all ways back up you efs folder

the sad thing there is mine I don't have my backup

Try NV restore (If you have it Pre-backed up on your phone from factory- at least mine did not have on the N910C but it existed on my N910F) ... Dial: *#0011# , then Menu>Back, then Menu>Key Input> then type Q0000.
After that I don't know where the NV backup is (I forgot, and I don't have the phone now), but you should be able to search here on xda or google it up...
I hope your Exynos has a NV backup....
Good luck
