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.

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:

Network Subset Lock
SP Lock
CP Lock

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?

Alright, so first of all, my Samsung Galaxy SIII got some damage, and then we brought it to a repair shop. They changed the motherboard, and then returned it to us and it was working fine. The only thing is, the Android version is still on 4.0.4, and whenever I boot the phone, a T-Mobile bootloading screen appears, and it annoys the hell out of me. So, I flashed Android 4.3 Jellybean using Odin. Yet, after the update finishes, the phone won't make a text or a call. It always says 'Not Registered On Network'. So here are some notes of the phone's status...
1. I tried to use Ariza Patch, yet it didn't work.
2. The IMEI's number is not changed to 0000 or anything, it's just a 15-digit number and has a '/01' at the end of it.
3. The signal is full.
How could this be fixed? Is there anyway to fix this? It would be very much appreciated. Thank you!
Take it back to the repair shop and tell them they botched the efs folder after their repair. You might be able to get a network by reading the sticky thread on efs, or the patch thread but you will always have problems with updates unless you get the efs folder sorted by a professional.
I did return the phone, then after that, they replaced the board again. After I tried to update it to 4.3 once again, the same thing happened, still not registered on network. :/
Right, i've seen a lot of people have trouble with their phones not identifying their SIM cards, and i myself faced this problem awhile back, i upgraded to Android 6.0 on my Honor 7 PLK-01, after i wasn't happy with it i decided to downgrade back to 5.0.2, running B130, and after the downgrade my H7 no longer identified my SIM card. The only thread related to this was someone asking how to CHANGE the IMEI of the H7, and apparently asking that was against XDA rules, but i read through the rules and saw nothing against it, unless i missed something, but i hope this isnt against the rules.
First i'll try to explain what an IMEI is based on my little knowledge, the IMEI is needed for your network operator to contact with your phone (or sim, im not exactly too sure on that), and if your IMEI is missing, your sim will not work.
Basically, here's how to fix/get back your IMEI 1 & IMEI 2.
ATTENTION, IF YOUR PHONE IS ROOTED AND HAS A CUSTOM RECOVERY, YOU NEED TO UNROOT YOUR PHONE AND GET RID OF THE CUSTOM RECOVERY
STEP 1
Check what your phones build number is, you can do this by going to Settings > About Phone, you should have your Build ID listed in here
STEP 2
Go to NeedRom.com on your H7 and download your corresponding OS update, for example my phone was B130, so i downloaded the B130 > B140 update, i would post the link but apparently i can't post outside links since im a new user
STEP 3
After you've downloaded your update, you don't need to move it to any dload folder or anything, just go to Setting > Updater, click on the menu button on the bottom of your screen, choose local update and it should show your downloaded update there, click on it and you'll be granted and option to restart your phone, click on restart and it should take you to the install screen.
after it's installed, your phone will restart and your IMEI should now be restored, and your SIM should be working again.. You should notice it instantly from your SIM working again, but you can also check it by typing *#06# into your dialer
i personally didnt find any other way to fix the IMEI on H7, this was the only way i got my IMEI back.
If this worked for you, please leave a thanks on this post :angel:

Hello everyone, I'm a desperate noobie here trying to fix this issue for three days now.
So as stated above I have a Samsung Core Duo (SM-G335H) and three days ago I connected trough SmartSwitch and it offered to update my phone. I agreed and during the middle/second half of it my laptop and phone just crashed. I revived both and SmartSwitch told me about the update failure and I made an Emergency Recovery. After that recovery, at first, everything seemed to be working normally, but on the next day I noticed: "Not registered on network " error. It recognizes the SIM card, but when you try to find a network it says "Can't connect. Try later." and so on. I can't call, other peeps can't call me.
I have been researching this matter for days now and am very upset about this. Some say stuff like Odin/flashing/third party tools/settings, I don't know what to do, as I don't have much experience with those things.
Btw, my IMEI is not null, it is being displayed (so I guess the EPF folder is not damaged). The APN settings (I'm on T-mobile) are still there, I don't know what to fix about them.
I am running 4.4.2 KitKat and my Security Patch Level is dated 2016 if that is of any relevance...
I also did a hard reset: nothing. SIM card works in my other phone, so it's not damaged. I just now saw that the end symbols in my Baseband version and my Build number don't match. Could that be it? I've seen people recommending updating manually/flashing with a modem file. How do I go about this?
Also: my phone is rooted. Only that I very clumsily attempted it months ago and before this matter here I would have problems with binary updates and what not, "phone is not rooted completely", I already fixed that issue though, it has SuperSu on it.
Anyway, I may have messed up somewhere along the way leading to this problem.
Please don't recommend me reseting/rebooting the phone again or just re-inserting the SIM card, that doesn't fix it.
I welcome any other suggestions, I hope somebody can help me.
Hi,
So yesterday I successfully unlocked my Galaxy A50 from Three network and ported my number to 48 network. Went to a phone fix shop to get the phone unlocked and it took about 20 minutes (cost me €25). Everything about the phone and 48 network works fine. However, when I went into Software update in my settings and tried to download and install the latest software update, I receive the message "Your current software version isn't supported. Visit a service centre".
I never had issues with updating software before and after checking online it seems that maybe the software updates are carrier locked (to Three network) and that if I want to update the software I would need to put an active Three SIM into the phone.
I rang back the guy who unlocked the phone and he said that people never come back to him with this issue after unlocking their phones, but if I wanted he would be able to manually update the phone and in the future it should update automatically, but this will cost €35 as he said he may need to backup everything and upload it again and it's a lengthy process.
It's either that, or find a Samsung Service Centre in Ireland (can't find any on website) or put a Three network SIM in any time I want to update.
Does anyone have any experience with this? Would really appreciate some help!
