Galaxy S II has no Network upon further inspection the phone doesn't display the Imei, bluetooth, wifi mac address.
Its not in flight mode, I restored to factory settings, tried couple of sims as well.
Is it a software issue or hardware issue??
Is likely flight mode. Press power button long and try the option flight mode or data connection.

still the same its not in flight mode or any other settings tho. I have used a galaxy S for 8 months
Replace sim card in holder .
jje
did try all the possibilities.
NEW PROBLEM : Once put into flight mode,i cant get rid off flight mode and the phone doesn't charge anymore?? Please tell me its a software issue
UPDATE: The phone is charging after doing a factory restore, but now i found out when i go to mobile network, it says SIM CARD NOT INSERTED? Sim card tray issue? hardware??
DOUBT: is there a chance the phone to get network locked??
UPDATE: when I Enter *#7465625# and see the following:
Personalization Status
Network Lock
Network Subset Lock
SP Lock
CP Lock
Phone is from singapore, looks like it got locked automatically?
things are getting more complicated my doesnt have a imei
when i check imei it doesnt show
NO imei copy back your backed up efs folder as per thread dev section.
Try factory reset rtrey flashing a stock rom .

Yup, sounds like an efs issue. Hope you backed that up.

Yea, this is the exact thing thats happened to me (Indian version).
Fresh out of the box phone, worked fine for the last 3-4 days.
Now I'm out on a vacation, and the network selection on roaming was flaky, I was toggling the network selection manually/automatically a few times to get some network, and the next thing I know I no longer have a IMEI (shows unknown) , and the same for baseband ( shows unknown) .
Tried factory resetting , etc, not helping. Will get back home and have the phone repaired/replaced.

This airplane mode sounds dangerous. Unfortunately it may be a necessity when you are travelling etc. Hope there is a known fix or one comes out soon. Until then I will keep my /efs partition backup in 3-datacenter redundant storage place along with my laptop and ext.hdd.
i just recieved an sgs2 in uk and it has this exact problem out of the box.
grrr
if anyone wants to point me to a stock rom for it i'll try flashing it
erm, i dont think flashing will help here.
I reckon that missing IMEI means the /efs partition has been wiped out/corrupted, and that is something which cannot be restored by a simple flash.
finally, after almost 12 days, lots of running around, I finally got my S2 working again.
The service center had to send the phone to their head office since they hadnt received any service info on the new model till then.
They changed the PBA apparently , and finally reflashed it and gave it to me.
They claimed that the flashing was an online process and samsung india service servers were down for nearly 2-3 days, accounting for the additional delay.
Just like my I9000, but I dont think it is the same problem and same way to solve.
I rooted the devise and deleted the nv_date.bin and the nv_data.md5 in EFS file with Root Explorer, and renamed the .nv_data.bak into nv_data.bin, then restart, problem solved
I have exactly the same problem as you guys are talking about. Really weird. The /efs directory, where is it located? Is it located in the main "Root" or is it in a specific folder? I would like to try the thing with the rename trick?

Hello everyone,
I have Samsung Galaxy S2 international GT-I9100. It fall into water. After that everything working fine excerpt IMEI null/null, Baseband Unknown, No SIM Card Detected. I exhibited it and dryed for a month. When I compiled it up again, same problem.
After that I decided to change the moatherboard. I bought new one, change it, turn phone on and same problem!! After that I install new ROM via Odin. And the problem still exist! How this is possible?? Oh and I want to mention that I can't access service mode. When I try to access it service mode is opened but menu is blank!
What you think the problem is?? Maybe smaller motherboard, because the small one at the bottom of the phone I didn't change. I am very desperate after so many tries so please help me.
Thanks a lot
anyone???

most probably your efs folder is corrupt or some hardware faulty. Do you have any sort of efs backup with you ?
If you have no backup, you're probably boned. Download as many stock roms as you can & start flashing. If that doesn't work, take it to a local mobile repair shop; many have equipment which can re-write the IMEI to the device fairly cheaply.
Thanks for answers, no I didn't make any backup for efs, so today I will start flashing all available ROMs for my country if this will not work I will take it to the service.
So.... I bought a TMO Tab 10.1 and being a habitual rom flasher and tweaker I proceded to root and flash xxxx onto it the first day. Life was wonderful and everything worked fine.
But..... being a flash addict I couldn't leave well enough alone. I wanted more. I found this thread ( http://forum.xda-developers.com/showthread.php?t=1336659 ) and proceeded to attempt the appearingly simple task of unlocking the subsidy lock so I could throw my ATT sim in the tablet if I wanted to. Things went terribly wrong art this point.
I followed the instructions step by step and yet now I have no cellular connection at all. Everything else seems to be working fine though.
What I need from the geniuses here on XDA is some guidance on how to restore my cellular ability. I did copy over the EFS folder to another location so I do have an original back up, but I am unsure as to how that is supposed to help? I tried copying and replacing the hacked/ modified EFS folder with the original folder after I lost connection but it did not restore my connection.
What am I missing? Should I flash a new modem? Should I just Odin back to stock and start over? Will that recover my original EFS settings or am I hosed?
Any ideas or help would be appreciated immensely.
So in case anyone searches for this..... I used Odin and flashed back to the stock TMO 4.04 firmware that i got from sammobile.com. I got my signal bars back and seem to have a connection of some kind as my signal bars go up and down. I also threw in an ATT sim card and it didnt reject it or ask for a unlock code.
However.. and this is a big problem, I have that stupid generic IMEI number still. You know, the one that starts 004999 so now I have to fix that. TMO hates tablets with a generic IMEI number and doesnt seem to let them on their network. I do have a backup of my efs folder so it wont be impossible, just a hassle.
Ok this is whats happened so far.....
My daughters i9300 Phone's battery charge port was not working but instead of taking to it a shop to get fixed she purchased a faulty one off ebay to swap over the board.
But opening the ebay one it shows i9305 so I carried on swapping it over
After starting the device it shows i9305N on boot screen
Flashed a few Roms but each one shows *#06# : null/null
Sim not inserted so cant get into APN Settings

Have tried the one which was in her own phone but same thing happens
Everything else works fine apart fom this signal issue and imei
At first when I started the one from ebay up it was in Korean and I put her Sim card in it and it showed signal
So after wiping it and trying Roms I am not sure what modem or other files where in this phone
Is it just a modem issue or something else?
One which installed just now is I9305NXXUFNI4_NEEFNI4_4.4.4_KK Which I know is Nordic and I am in the UK
Have also tried UK Roms and same issue!
So does anyone have PIT,CSC files for Odin that I can try flashing and with Stable and preferably bloatware removed ROM
Thanks
Anyone?? tried new Sim Card slot and still shows this.....
Hi,
Its been very recently that I bought SGS3 i9300 *exynos not qualcomm, in used phone and I'm pretty much in the dark what material does SAMSUNG puts into his phones to make them full of *beep*.
I was running XXELKC 4.1.2 firmware and I decied to just root > recovery > CM12.1 or CM13 SGS3.
Well everything went well but I ended up with no sim card error. Then I thought that might be my sim card is corrupted so I put in a newly replaced microsim card and put in the phone still no good.
Then I did wipe system+cache+dalvik+data and installed CM13 from TWRP. Still ended up in no simcard error.
Then I got to know about XXEMG emergency zip radio which is cross-efs compatible so I flashed that one. I ended up in NO IMEI/Baseband
I flashed XXELKC PDA file back and phone booted with its own IMEI number preserved.
Now I have working DATA connection but phone doesn't register on network for calls/sms.
What is the possible issue here?
I cannot find working modems link as the REF thread has dead link to modems.
I do not know how to fix this phone, and I've made myself a promise that this is my first and last samsung phone ever. Please help through this one for the last time, even it means working phone on a JB 4.1 firmware but I want the simcard/network/calls working to resell it and get rid of it.
Thank you for actually roaming around in Q&A section and taking a look.
Nobody?
