insert the sim properly with the golden plates down and the cut end outward. Then go to settings>>>wireless>>> untick the flight mode.

I think it's broken

Try reflashing back with the original stock rom.
It looks to me the baseband is not installed properly, and therefore unable to access IMEI, without a working baseband, you are unable to access the phone portion.
It could also be that the nv_data.bin file is damaged due to a bad sim unlock hack. If that is so, you will have to rebuild that file.
Again, try reflashing back to original stock rom, before trying to rebuild the nv_data.bin.

(Sorry to resurrect old-ish topic, but I think it's better to continue here than to make a new one.)
Same problem here, except the only custom thing I've ever run on this phone, is apps from market. I'm running SPB Shell 3D (legal version, but not through Android Market but the other thing SPB was selling their programs through... Handango? Not that it matters.)
The phone has been running ALMOST perfectly since day one. I can only remember two occasions that the phone was in "no reception" mode (the O with slash through it) and toggling Flight Mode on and then off fixed it both times before.
However, yesterday I noticed the icon again, thought nothing of it and switched Flight Mode on. It never went back on again. Googling the problem I bumped into the imei/baseband thing and sure as not, when checking my phone's data there is "unknown" in the baseband version and IMEI is empty.
Trying to enter Mobile Networks settings results in "insert sim" notification.
The phone is (OS-wise) completely stock, I think the only thing I have ever done to it since then was to update it to 2.3.5 via KIES when it became available.
Phone is unbranded and not simlocked and never was. The only alterations are the aforementioned SPB Shell 3D and WidgetLocker. And of course a bunch of "normal" apps, games and such.
I placed a call (which went unanswered for all it matters), then after a short while (five minutes or so) noticed the "no reception" -icon. Then all went to hell.
Tried with three different SIM cards, none work on this phone, all work on other phones. Currently SIM working in Galaxy Gio.
I plan to take the phone to repairs under warranty, I'll let you know what they say and what happens to the phone if I remember.

help!
I have the same problem. The phone is 5 weeks old. I dont know what happened afternight with it :-(

READ the restore IMEI restore EFS posts but first backup data and try a factory reset .
jje

In my case, it was perhaps a bit more extreme. I sent it to the repair shop under warranty, it came back practically new. They had changes most of the innards, including the motherboard. Something had apparently shorted itself and cleared some chip. Hadn't gotten anything more specific out of them and I've even sold the phone since then and got this Galaxy Note.

imei
just a precaution.....alwayz backup ur efs a tool is hell kat tool which backs up ur efs folder as image....so any prblm such as diff pcode,imei etc can b restored within sec...always save ur efs folder on pc...an certain apps like root exp etc work on rooted phones..i messed alot wiv my sgs1 an sgs2 but thanks to the developers for creating this great tools....

I have a similar issue with my SGS2
I ran my phone battery until it died and when I rebooted the no-network sign came up.
Now, it show's no baseband, no imei and if I dial *#1234# it shows up as Phone: Unknown
(I think it used to say GT-I9100)
I had a backup efs img and files from way back, and restored that several times along with a factory reset and tried installing different modems both original and others.
It's looking pretty bad.
Any thoughts on what else I can try to diagnose this before I send it back?
TIA, Daniel

Try getting a new one from your warranty?

Eh I wish I could, bought it from someone (vibrant t959 is not available in stores here in Canada) so it’s either fix it or lose it

Thanks for trying but I tried restoring IMEI (nv_data.bin) technique from the link but it does not help, my vibrant does not want to repair those files automatically, and when I delete efs folder contents it restores nv_data but the file is empty. Also it's strange that going back to stock with odin does not wipe data... I thought it should
Had to go to "specialist" to fix it... He did it ... my imei is back (but nv.data.bin still empty ). It seams that my sim card was corrupted also... eh at leas it was fixable, but how .. no idea.

Is corrupted IMEI GS2 not fixable?

Ok guys! This is simple, i bought this GS2 from a friend a couple days ago. He told me the phone had no IMEI and since i have seen this before on other Galaxy S variations and have been able to fix it i thought it was a good buy. Thing is i didnt realize how hard it was going to be to fix that. He tried to unlock that phone who knows how and it completely messed up the efs folder. I have tried the 9 step Imei restore method and some other tricks with no luck. Problem with this phone is that it doesnt even have a dummie imei number. In fact, not even zeros, just nothing when i try to check for an imei number. Any suggestions for this. Or should i just look for someone to buy the lcd and dump the motherboard to the trash?? Thanks!
Without a backup of the original, working EFS folder you are probably more or less stuck. I've been in the same situation before and ended up having to get the phone replaced.
Contact a member on here called Odia via PM. He is sometimes able to recover IMEI's/EFS details when everything else has failed (for a small donation). If everything else you've tried hasn't worked, that's probably your last chance.
Yep odia said corrupt efs was no problem to fix.

I'm facing this as well: imei blank, no baseband, stuck on flight mode. I've tried everything, no luck. I'm fixing it for a friend, would be nice to come with some results up!

Here's the only fix I know of for a galaxy s2: http://www.youtube.com/watch?v=iY9cDkj4CCw! If it works, make sure to make multiple backups of your efs folder on sd card/pc/drop box etc!!
You can view your efs folder using the Root explorer app!!
Here's the download link for the galaxy s2 kTool fix: https://play.google.com/store/apps/details?id=net.hellcat.droiddev.ktool&hl=en Good luck!
If all else fails, your only other option is here: http://mobiletechvideos.mybigcommerce.com/samsung-galaxy-s-ii-imei-efs-repair/
You can try to fix the efs partition following this guide : forum.samdroid.net/f70/repair-imei-s2-5729/
You'll probably get a generic IMEI after that, then contact the guy he will set back your original IMEI. I had exacly the same problem and it worked !
Wow guys thanks a lot for all those replies! Ill keep in touch and tell you how it goes!
Thank for your help jje, I've tried many methods but none of them seem to be working. (Done factory reset, installed CWM recovery, wiped caches, adb shell) I've a feeling that this phone needs a main board as well. He's got insurance for his phone so at this point, I think, it's not worth the hassle anymore.

[email protected], even changing almost any galaxy S lcd is not worth it when it breaks. Have you seen the prices of those lcd replacement screens? We do it for the sake of learning. Although in this case you might be right, because just like your phone this one doesnt even have a baseband showing. But still im pretty shure its a software and not hardware issue. This is about something that went really wrong while unlocking or trying to do something like that with it. Too bad i dont even know what happened with this one. No efs backup or anything
What actually happened is my friend went into this badly network covered area, lost the signal and he was back to a place again, where is a strong network coverage the phone just would not log on and stuck in flight mode.
So my s2 was on gingerbread rom and I decided to flash 4.1.2 via odin. Phone booted up and asks for sim unlock code. I learnt then that it locked the phone. I used Galaxy_S unlock https://play.google.com/store/apps/...sMSwxLDEsImNvbS5oZWxyb3ouZ2FsYXh5c3VubG9jayJd
but it didn't work so I restored the efs. Then I tried this Galaxsim http://forum.xda-developers.com/showthread.php?t=1846451 and it says unlocked so rebooted phone but when making or receiving phone calls, it disconnects. The paid version from play I havent tried but Im guessing will be the same?
Imei still shows so Im not sure what I have done wrong.
I have efs backup from both of those apps and also a efs.autobackup in the root of internal storage date in January. Not sure how that got there as this phone had GB over a year.
Please help
Do you get any signal at all?
The paid version won't help as this could be a modem issue.

Yes there is signal, data connection works. I then tried reflashing GB, restored GB backup, flashed ICS and same problem

No phone function

Hi all. First post so be kind! I have spent hours searching but cannot find a solution which works, or anything which comes close.
I managed to get my hands on a used S5830. The phone boots and everything seems as it should be other than it registers no sim, no signal (or rather a no entry sign where the bars should be). The IEMI, baseband version, network & mobile network type all show as "unknown".
My first thought was to check the efs folder, but there isn't one. So I then tried to flashing various different firmwares, no luck there either. I also tried flashing different modems, again, no joy.
The phone also turns itself off or reboots about every 10 minutes or so. Even if the phone is turned off it will turn itself back on. I have to take the battery out to stop it draining.
The phone was already like this when I got it, I don't know what the previous owner did to it.
Current setup is...
GT-S5830
Baseband: unknown
Kernel version: [email protected]#1
Build: GINERBREAD.XWKS3
Any help appreciated. Cheers.
Half bricked. How is your emei?
the Mafia aka KASE ARe For TroLLing
Its half bricked coz no imei. Sorry didnt see ur post.
the Mafia aka KASE ARe For TroLLing
Dang. What actually causes the problem do you know?
Hmmm...what did u actually do? Try reflashing again via odin. If not,send it to service center and say u updating via kies
the Mafia aka KASE ARe For TroLLing
I bought the phone cheap, not sure what the previous owner did to it. Probably tried to root it. Have tried various firmwares via odin, single packages and multiple. The phone/modem just doesn't seem to flash.
Pity,it must be halfbricked before u bought it. Get ur cash back
the Mafia aka KASE ARe For TroLLing
Maybe it was packaged with Froyo? Try that (if this was there in your various firmwares ignore this )

No. The old owner was trying to unlock the phone but failed, lost his IMEI, and no way to get it back..

I did try Froyo, it was the only multi package I could find.
The previous email attempting to unlock it makes sense as it's not completely bricked.
I don't know how possible it is to reconstruct the imei. I have read several examples and guides of fixing or resetting them but it relies on having the efs folder in the first place.
It's quite fun learning from a broken phone!

The folder is in a partition on the phone whichs is easily corrupted when you try to access it. It's as useful as an iPod now.

I9100G no imei no baseband

Ok long story short. I have a i9100g that came to me only displaying 3 icons (phone ! computer). Using the method I found here http://forum.xda-developers.com/showthread.php?t=1619571&page=21 I managed to bring it back to life but no imei.
I managed to write so far a stock 4.0.4, 2.3.6 and 2.3.4 trying to repair the imei problem. I have acces to a good efs folder of a i9100g but even after I replace it on the phone the imei is still unavailable.
I tried using the gsII_repair but it tells me its done but it isnt.
I tried using Efs pro software. With the phone's initial efs files it gave me an error at nv recovery but with the good ones I have the software says everything is ok.
My question is. Should I give up on trying to find a software based repair and try for hardware ?
Or if anyone has any more ideeas that might help I would be glad to try em all.
I must add I have no ideea how the phone got like that before it came to me nor do I have any clue where the phone is from.
*edit*
I am terribly sorry for posting in the wrong place. I didnt find a q&a for i9100g

Help unknown baseband no imei no signal on shw-m250s

So my phone is shw-m250s T (I don't know but like there's Olleh version this one has T logo on it so it may help)
My phone was first on 2.3.5 perfectly working without no problem but only volume button not working so i got those fixed and this whole adventure began. Since i was able to go into download mode and flash things i wanted to convert my phone to i9100 so i did using this thread:
http://forum.xda-developers.com/show...php?p=24705250
Then later i learned that there's freakin 4.0.4 ICS official update on my phone so i freaking installed it and this all started from here.
First i was getting random signal lose and sometimes no signal always but i didn't take it seriously coz reboot was temporarily fixing this problem.
But since it was annoying me and i wanted to try new roms out there i tried to install Cyanogenmod v10 (i think) and after some try it worked and was nice there but totally no signal no pin code ask or whatever then i switched to Paranoid Android (latest version with halo and stuff)
It was even more nice than cyanogenmod and i enjoyed it but still no freaking signal or whatever but also this rom was draining my battery like hell even it's locked it drains my battery and when i sleep and wake up it's 13% from 99% around 8 sleep. Then i searched all over internet trying whole lot of things but i still didn't find it. I learned that this all things are because of corrupted efs folder bla bla and then i tried EFSPro Backup yeah it looked nice and it said it's done and gave me tar file with efs.img in it. I tried restore and it said success but still no signal or whatever please help guys i need all your help to fix my phone and get it to work.
My phone specs in case of need: (It's all lost way back then but i'm looking things back)

and all else is korean strange things and why my imei is not here...

Looks like this won't work for me because i'm not getting nv_data file after deleting efs folder maybe because i cant go r/w to delete efs but i deleted files in that folder (not efs folder but things in it) so maybe it didn't
But i got my real imei thanks to gmail dashboard but even i got my real imei does that mean i cant have right baseband for it? still not usable and if it is how can i edit it to my real imei?
I think i gotta sleep now and will come tomorrow to check out and try to fix my phone for real or my phone is gonna be ipod lol
