Hi guys, this is my first post and I just made the biggest error ever.
My S2 was (well, still) locked and I tried to unlock it using the Helroz Galaxy S unlock apk, I made the EFS backup, and then tried to unlock it, my phone rebooted and now I have no signal, no gsm, no NOTHING, my sim is completly blocked, I did *#06# and NO imei found. I still have the EFS backup nv_data.bin etc but when I try to apply the BACKUP from the apk it says the backup or EFS folder is not found.
I have no idea on what to do.. my phone works and wifi works, but 0% signal from sim card.
Urgent help is needed, please guys, I beg you.
Sorry for my bad english

So... Tonught I was happily having a game on draw something with the mrs.. Then noticed a no entry looking sign where my signal was.. Took the sim out wiped it put it back in.. Same again.. Thort strange.. Must of crashed or something..
Anyways..
Did a factory reset. ( settings - privacy - factory reset)
This didnt work either nor did hard reset using the code..
Anyways.. Looked all over the internet and most forums said basically.. Warranty.. Send it back..
As i baught it second hand wasnt sure of wether i could so kept looking....
I then found this.. And my god it was a godsend. I was convinced my phone was dead..

Are you sure busybox is installed/updated?
As someone said make sure your busybox is installed correctly.
My phone was as stange as hell.. I set up a lock screen before it all happened.. For some reason after a factory reset.. my lock screen showed up. But for some reason o could draw any dots and it would unlock it..
Also i had no imei.. No baseband. No bluetooth.. Wifi would work. But anything tondo with my gsm sim care would not work..
When using GS11_repair.. Skip the first tab and goto the repair tab. Do everything in order on that page.. The unlock part i didnt do as my phones the unlockes debranded firmware so didnt need it. I only did the first 2 steps and magically everything just came right..
Hope this mini guide helps.

Apparently the problem is your nv_data file is corrupt. Which is in or around your efs folder which has all the information about your phone [imei baseband etc]
backing up and restoring your efs and deleting the old nv_data file fixes the problem for apparently 9/10 gs2's.
MAKE SURE YOU BACK UP YOUR EFS.. 2 FILES SHOULD BE BACKED UP IN THIS PROCEDURE. IF I WAS YOU.. UPLOAD THESE 2 VERY IMPORTANT FILES TO YOUR DROP BOX OR WHATEVER SO YOU ALWAYS HAVE THEM SHOULD YOU NEED THEM.

This only works in few cases and you should not use gs_repair because it creates the efs filesystem with the incorrect parameters.
No idea mate.. All i know is it worked for me.. Device is fine now

GSII_repair was what screwed my EFS up months ago. Beware!
Apparently theres other tools that do the same job. The info i posted was the only info i couls find when it happened to me so shared the info with anyone having the same issues.
I dont know what this software does. I didnt do all steps stated on GSII_Repair.. I backed up my efs then mounted it.. Didnt trust deleting anything and everthing was fine for me after a reboot. This was performed on GB stock 2.3.4rom
Actually did me a favour as was forced to root. Now running ICS so happy days lol

can you help me restore my mobile
Hello, I was trying to unlock my galaxy tab P7500, and for some reason I lost the efs backup, or it got overwritten or something, base line, I don't have the backup, now the IMEI is 004999010640000 and the serial number is 00000000000, obviously, it does not connect to the network, I've tried every post I found that states I can restore my IMEI, flashed older firmware, flashed the original one and many other things, but none seems to work, so now I really don't know what else to do, I know my IMEI number and my serial because is still in the sticker on the back of the tab, and is in the sticker on the box, and is on the purchase receipt.
So any ideas what should I do?
GT-P7500 from movistar venezuela, now on Official ICS LQ8 ITV
Do u still have the imei number that on the back of ur tab? If u do I advise to you is going over to t-mobile gs 3 dev section. They have a tool call nv and imei injection and give it a shot.

Honestly, you'd need some one to send you their EFS backup (who's on the same carrier and model). Then you'd need to extract it. Then edit it to replace their data with yours.
But I don't think your going to find anyone willing to do that. As it's a HUGE risk to them. So I think your only bet it to to a warranty or repair 'call' with lg if not your carrier.

Hi man. People keeps telling you to install new modem, kernel etc...but i think you have corrupted EFS folder.
I hope you backup your EFS folder before flashing ANY rom because, otherwise you will have to go to some repair shop.
Well, I don't understand a lot, but I think you could check if you didn't lost your IMEI. Go on Settings > About Device > Status and check if your IMEI still there.
If it is, I don't know what could be. You could try flash another modem or restore a backup (if you have one) with PhilZ Touch but if it isn't, that means you lost your IMEI. I remember I read about that somewhere, that there is a risk of losing IMEI when you flash a lot of ROMs.
If you have backup from your IMEI, just restore it. If you don't, I don't know what you could do, but I guess you could still do something.
One more thing: Wi-Fi works?
Like I said, I don't understand a lot, so everything I just said may be very stupid. Or not. Sorry for bad english.

same problem now as mine my IMEI just became 350050500009692 /01 emergency call only why???
some nice paper weights at least lol none of you have efs back up ? tried restoring it if you do common rule with samsungs all ways back up you efs folder
the sad thing there is mine I don't have my backup
Try NV restore (If you have it Pre-backed up on your phone from factory- at least mine did not have on the N910C but it existed on my N910F) ... Dial: *#0011# , then Menu>Back, then Menu>Key Input> then type Q0000.
After that I don't know where the NV backup is (I forgot, and I don't have the phone now), but you should be able to search here on xda or google it up...
I hope your Exynos has a NV backup....
Good luck
