Today i've recived my fixed vibrant from samsung, download and recovery mode working. I've rooted, unlocked (by the tutorial with Reparation_nv_data.jar) and installed bionix final version. THEN I started to use the phone, internet works fine (i have 3G and i can download things and everything). But when i try to call or send a message it is not registered to network. Say that the SIM don't allow it. My imei has changed (or already come with this from service i don't know) to 004999010640000. There is some way to fix this?
did you do a backup of your original efs folder?
yes, i've just restore it. Now i get registered to the network but when i call it just keeps calling (don't do any sound) and if i try to end call it freeze
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?

Well, I've got an issue.
On my S5830i, I was getting a ROM, wiped the data partition and cache as I was supposed to, and then after discovering how bad it ran, reverted to my stock CWM backup.
However, the phone no longer has an IMEI. It only allows emergency calls too. Strangely, in the about section, it still says I'm connected to my network (3).
So far I've tested:
- Dialing *#06#, returns nothing.
- Entering those long numbers that enter engineering mode, they didn't work.
Any help is appreciated!
Thanks!
After flashing new ROM to my device I get 'emergency calls only'. After I tried searching all the threads i get similar solutions which don't work in my case. my imei remains intact and i still don't understand why i can't connect to network.
It started with galaxy S3 i9300 aftet flashing stock ROM from sammobile which fortunately was solved by Ariza Patch.
Now for my GT-S7580 I lost mobile network after flashing cm12.1 by Sandpox and I cant find any app(like Ariza Patch) to restore it. I also tried a stock ROM from Sammobile.com but i still don't have network. I tried post on the related threads but my problem is not solved yet.
I tried all these solutions but none seems to work:
-searching mannually
-turning radio OFF and ON again.
-switching phone off, removing battery and SIM card and on again.
-turning flight mode on and off
Please help on any way to get my network working. My Carrier is Safaricom Kenya
I have a Jiayu S2 double-SIM phone, running the most up to date official ROM (4.4.2).
This ROM had a couple of bugs (no GPS and no notifications to external devices such as smartwatches), so I wanted to check other available ROMs. Using the Flash Tool I have tried a couple of the ROMs in the needrom site (https://www.needrom.com/category/jiayu/s2-jiayu/). In particular, a couple of versions of the official ROM, another ROM known as Salamander, and an unofficial port of Cyanogenmod 12 (in which the camera was not working).
The issue is that, for some reason, at some point my phone has stopped getting phone signal. The SIMs ask for the PIN on startup, but there is no signal. I have reverted to the original ROM; plus done a factory reset, and I could still not get signal.
The APNs for both SIMs are fine. Then I have realised that the IMEI was empty. Luckily I had it written down, so I have installed Xposed and the Device IMEI Changer, with which I have been able to restore the IMEI. Now I can see the IMEI on the Settings - IMEI information, as well as with *#06#.
But still, now with the original ROM, and with the IMEI restored, I still cannot get phone signal. I have tried setting the phone to flight mode, restarting, selecting manually the network... When trying to manually select the network I can see several networks, but the phone will simply not connect to the one it should.
Any idea on why could it be that I cannot get phone signal? Thanks.
After trying everything, including restoring the IMEI with Xposed, I have finally managed to restore cell service by restoring the IMEI with this tool: https://play.google.com/store/apps/details?id=com.cryptotel.chamelephon
