its so annoying that it make me miss many calls.....
i rely need somebody's help orz
what should i do?
im using cm7 by quarx and i tried to reflash cm7 before, but not works :S
I have experienced the problem when I first flashed CM7. After lot of frustration, I found that the sim card dose not fit snugly in the sim card slot. And after a drop, the sim card had moved from the contact. Removing the battery and setting the sim card properly solved the problem for me. Hope this helps. Another thing you might look at is the setting the right base band. And also select the proper network type in the test menu [dial *#*#4636#*#* and go into phone information and scroll down.] Sometimes this gets reset to WCDMA

Help please anyone.
Earlier today my phone lost service...i wasn't too bothered as I was home and the wifi is still working well.
I thought there was no orange service! Turns out my sim card isn't being detected (nor is any other one i've tried)
I did drop my phone early...but it's in a hard back case and it landed on its front and this has never occurred before.
What to do? Will a repair cost a bomb?
check ur IMEI and baseband...
i gues they'll be unknown
yep unknown?
This just happened to me just few minutes ago. Try turning off your phone, remove battery and SIM. Re-insert battery and turn on without SIM. If your radio service is restored, turn off and turn on with SIM this time.
This seems to happen to me whenever I try to calibrate my battery using the app in market by NEMA.
I'm going to have a backup of my efs folder and root explorer app now because I'm scared.
^ thanks will try that!
My airplane sign is on though! and has been for ages now-despite airplane mode being disabled?
Lol okay so I have two issues...sim problem AND
the phone refuses to switch off flight mode (despite the fact it's not activated in settings) Wifi comes on but bluetooth won't as it's in "flight mode"-sigh
If you have some radio service restored, then there is still some hope:
Go into phone dialer, punch in *#*#4636#*#*. Then go in Phone Information, scroll down, and there should be a drop-down box selection there. Select "GSM/CDMA auto (PRL)". Wait few seconds. Hit your menu soft-key. Select "Select radio band". Select "Automatic", OK, then go back to Phone info Menu. Hit "Turn off radio", wait few seconds until you lose all radio connections. Then hit "Turn on radio" and see if you get your radio connections restored.
If you can't do any of the previous steps then your efs nv_data.bin file is probably corrupt or something. Try removing battery, wait few seconds, turn on phone without SIM, turn off phone, re-insert SIM, then turn on. Repeat instructions on previous paragraph.
If you're still SOL, then you need help from someone else. Try searching "efs restore" from the parent forum thread "Samsung Galaxy S II I9100". I found a thread with [FIXED] tag that may show some help regarding this.
My S2 is also in similar mode .. tried ur instructions but unable to start the radio please help
the same think for me
i had this with ke7 modem and when i changed to kh3 it stoped
Apologies for hijacking this thread but I have a similar problem in that I can't get a 3G signal either.
In my case, it happened when I was at my local cinema and I managed to pick up a 3G signal in there which I used to do a quick check of my email before the signal switched itself off.
Usually if the phone is out of range of a 3G signal, the signal would switch itself off then back on once the phone was in range of a 3G signal and yet, when I was back outside, I couldn't get a 3G signal.
I thought it was the SIM card at first but it's definitely not that. I finally managed to install VillainROM after much difficulty yesterday and it fixed a problem I had with the phone being stuck in Flight Mode but it didn't fix the problem involving not being able to pick up a 3G signal anywhere.
HI ALL, Im pretty new here. after so many tries finally i was able to install cm7.1 on my defy. but im facing some issues. before the installation i forgot to take a back up of the existing ROM so if i have to go back to the previous ROM how to do that? and also there is no network coverage after the installation. please please anybody help!!!!!!
Have a vibrant myself but I'm helping a buddy get cm7 on his defy and after flashing didn't have a network signal. I looked at the cm7 install guide and it referenced a defy base band switcher app for better coverage. Had him try that and he got his data connection back. Might want to look into it or read the guide.

If your previous ROM was stock that came with your phone, flash the corresponding SBF file from the sticky on the Dev section to go back to stock. If it was some other custom ROM, wipe data/factory reset in CWM and flash the old ROM. Make backup of your apps using Titanium Backup if you want.
For CM7 network issues, choose the correct baseband from Defy Baseband Switcher. For India, pick anything that is 900/2100MHz...
Also, make sure you have read as many guides and First Posts on important threads as you can. Here is a collection of good threads you can read for these questions, and more that you might get later:

Hello! Noob here as well.
I installed CM7.1 stable on my Defy (running 2.2.2 foryo) 2 days ago.
All went well, except that network connection is lost after a couple of minutes after boot. Sometimes it takes an hour or two but I still end up with no connection.
I've googled everything about it in the last days. I played with the Baseband Switcher and although most options in the BB Switcher work right after a reboot, it still looses the signal after a couple of minutes.
One thing I noticed, when the signal is lost, trying to set the "Airplane mode" will fail. If trying to set Airplane ON - the notification icon will not replace the signal icon and will also be unable to set Airplane OFF (since it didn't finish turning ON).
I also noticed that if I force stop the "Dialer" system app, then the Airplane notification ico shows up, but still there's no way to turn it OFF (it's disabled in the menu). After a reboot Airplane can be set OFF and everything works for another small period of time (..until baseband crashes again?).
Hope it makes some sense. I'm quite sure this is not an operator issue or hardware related, since my Defy worked just fine before CM7.1
Also, I am located in Romania, operator is Orange.

I have the same issue, except that it is much rarer (ranging from every other day, to even a month between such incidents). It can also be triggered sometimes when I turn off Wi-Fi and the device tries to regain mobile data connection (not sure if it matters, but I set the network mode to 2G on my phone). The battery drain is increased if this occurs without the user noticing - the phone seems to search in vain for the signal.
Using the latest SEA baseband on M1 (Singapore).

I get this problem too. Happens every so often when I'm at work. I've always put it down to a bad signal where I work but as I always turn the wifi of before leaving home it could be down to that. If anyone has any solutions it would be great
Ok, a little update on this:
At the office now, further playing with the Baseband Switcher, I ended up selecting "Italia RT 2.51.1" which has the same 900/2100 freq that my operator requires and it seems to work. Even getting 3G.
If "2.51.1" is some sort of protocol version, then all the other options I've tried were either 4.x or 3.x or even 2.21.x ..and none of them worked for more then 30 minutes.
Also, not sure if signal strength has something to do with this because I did a test, going to the basement of my office in order to loose signal, then back up and it worked - got the signal back, without reboot or anything.
Also, I would really appreciate if someone could explain in a few words what those version numbers mean (ex: "Italia RT 2.51.1"), as I know nothing about gsm bands and protocols.
UPDATE: Back home, lost signal again, after a whole day without any problems. Funny.
UPDATE 2:
So after much google searching and trying literally every option in the Baseband Switcher, I switched my SIM card with a friend's SIM and guess what.. IT WORKED! Even more, when I inserted my original SIM into the other phone after a few minutes it lost signal, too! It was a faulty SIM, that has just started to "die".
Conclusion:
- Keep playing with that Baseband Switcher until you get something that works for you.
-Make sure your SIM is working properly in other phones, otherwise ask your operator to replace it.
Thanks and hope this helps.
ZeDevil did you try using other Basebands to see if you get better battery life ?

Not really. As long as you have a working Baseband selected (with correct frequencies) I don't think it matters.
But overall CM7.1 has better battery efficiency then stock ROMs, or at least that's what I felt.
update:
Well, I had a play with the baseband switcher, realising i was on 'international'. I switched to uk t-mobile and from there it seemed to work much better. A slight blip at work today (think it's a bit of a signal black-spot though) but restarted and it seems fine again. I've also just realised it's gone 37hrs since its last charge too
Strangely my other problem, the backlighting on the soft-keys not working, fixed itself at the same time. dunno if these two things are linked or not?
i use the CEE one.
Hi, im having some issues with my signal on my N4...it randomly started a few days ago. This is what it happens:
While my N4 shows to be conected to my 2G / 3G network, sometimes (very frequent now) it totally drops the conection, the signal triangle seems empty, and going into airplane mode and coming back wont fix it, and when i log into the *#*#4636#*#* menu, it shows "Unknow" on a few options even on the preferred conection type, and i cannot choose any option there because it will go back into Unknow. The only solution is rebooting my N4, but this is just a temp solution because the problem shows up again not too long after its ON.
I have seen that if im constantly sending and recieving data, it keeps it conected longer, like when streaming a video. This problem started to occur while i was in baseband .48 with stock 4.2.2 rooted/unlocked. I did a complete wipe, and reinstalled 4.2.2 stock, but this time with .54 baseband, and the problem persist.
its been hard for me to find old posts about this problem in particular, seen other people posting about alike problems, even losing the imei number, but that doesnt happens to me, i still can see my imei number on *#*#4636#*#* even when everything else there shows unknow. I will attach an screenshot, its not in english, but i think you guys can get the idea.
details: My N4 didnt drop or anything, i already tried removing the simcard to check it, so i have no idea what to do now. I appreciate any help
Maybe your SIM card is bad or not seated properly.

Its well seated, and yes, a bad simcard is another option, but i wont be able to check that till tomorrow i guess, but just wanted to make sure this doesnt seems hardware/software side
I bought my used S4 and had problems with network. did a few things and didnt solve problem.
In my country (Bosnia and Herzegovina) 3g network isnt available everywhere, and on places where signal is low i am loosing my network..
In past few days i did and tryed next:
- Rooted
- recovery installed
- installed slimKAT 4.4 and gapps
- installed new baseband
- installed app Network from Play store and set my network to GSM auto (PRL)
- tryed typing secret codes to enter networs setups *#*#4636#*#*
and nothing solved my problem to enable 2g network...
When i am using 3g in a place which has good coverage of 3g network everything is fine, no drops... great...
When i maunaly set my network to 2g i lose network nothing happens, emergency calls only...
How to enable 2g?? installing new baseband? which one supports 2g on S4?
Solution
After a while it proved that problem is with the base band on the motherboard.
Removed hardware part of the base band , and put another one... it was a bit difficult because from the other side of the motherboard is ROM and because of the heat it removed also, so it had to be glued again.
After a while i installed again SLIMKAT and problems continued.. Phone froze, wasnt able to call because ACTIVITY PHONE ISNT RESPONDING, and it froze the phone every few calls, and it had to be rebooted, even that didnt helped sometimes, so batery had to go out.
Wiped Cash Partition, nothing happened, Wiped Cash and Dalwik, nothing happened...
Found somewhere that CONTACT SYNC and Facebook Contact sync disableing will help and guess what, it did...
Disabled all Contact Sync and for now everything is ok...

Looking for a little advice/assistance please.
Have flashed RC 5 ROM onto my Jiayu S3. All is looking good. WIFI, Bluetooth and SMS working fine. When I try and make a call and press send the signal indicator goes from medium signal to nothing with a cross and the call does not go thru. When you try and call the phone you get message that it is turned off or out of range. The signal indicator eventually comes back to showing medium signal again. It also seems to jump between 3G and 4G a lot. Every now and again it will work but takes a while from pressing send until it starts to ring. My IMEI numbers are correct. The SIM works perfect in my other phone which is a stock Samsung.
This problem happens in either SIM slot.
Hope someone can help. Tks Ken
