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.

thanks!, is that a web site? or a office? I'm currently in Bogotá, Colombia, so if your advice needs me to take the tab to a t-mob office I think is not going to be possible.

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

Hi folks! Im hoping someone can help me sort this out.
I rooted my n9005 using CF-root to install custom ROMs. I wanted to back-up EFS and searched google play store for an app, I found "Efs by BORIS.X.1" app.
This app is not to be used for NOTE 3 as per warning by the developer but I'm so stupid not to read. :crying:
My phone got into a bootloop and if I was able to pass boot up, after few seconds it would restart. I have scouted the forums for fixes and I have found one. I am now able to boot my phone normally but cannot make calls and sms.
My IMEI is unknown, I already fixed it using "EFS pro" tool, IMEI is showing now but still no calls and sms. I also noticed that the serial number is not the same as the one written at the back of the phone. I have read that restoring EFS solves this problem, but I don't have EFS backup.
To sum things up, the phone now boots up normally, IMEI is showing the right one, serial number still incorrect, can connect via WiFi, can't make calls and sms but phone has signal bars and says "Emergency Calls Only".
When trying to make a call, "not registered to network" shows up.
Im on MJ6 BTU firmware with root and TWRP recovery. I originally got my phone with MJ1 KSA firmware.
Im planning to bring my device to a nearest samsung sevice center but im not sure of they will accept it or if they can fix it even at a price.
It's been literally days since I had a good night sleep.
Please help. Thanks!
Having the same problem...How did you get your phone connected to efs pro? Every time I try my device reboots :/ Is it possible in recovery mode? Which recovery?
Did you find a final solution?
•You need to be rooted first.
•Make sure USB debugging is enabled.
•Dial *#0808# on your phone and select the same items in the image
•Connect your phone to your computer using the USB cable and open up EFS Pro.
I still haven't figured out the solution of my problem.
I brought my phone to the nearest Samsung service center but their solution is just to replace the motherboard which is very expensive.

Well i was trying to to flash a new rom on my D802 and accidentaly i deleted everything... a full wipe from phone menu ( not recovery )
Since there was absolutely nothing on the hard drive anymore ( i assume) Phils TWM coudnt find any folders .. i had to push roms to the phone through adb now the problem is that no matter what rom i install i get no connectivity/no service .. cant recieve any calls or use data... only wifi...
I tried re flashing...
Stock rom
Paranoid rom
G flex rom
Stock kernal and peak 5.2 kernal
Nothing has worked? How do i restore connectivity to my phone? Thanks
You have a problem.. Your EFS folder was probably wiped
I guess you could reflash your kdz and bring it into the service centre?

I bought this phone through Kogan shipped from hongkong... This will take weeks, perhaps months... I am not even good with reverting phone back to stock as if never happened...
Is there any other way for me to fix it myself?

Try irc. Channel. #LG-g2. May find a few folks who can help or lead you in the right direction. Assuming you didn't back up your efs ?

NomadCF said:
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.

Warranty service?
Yeah, if you wipe your EFS, flashing back to stock wont help. The EFS partition contains files individual to each device, you will probably have to return it for repair man D:
I've had the same problem too, my SIM card doesn't seem to be reading on my phone either; and it definitely a functional sim.

I'm sorry, xda mail somehow has been going to my spam folder.
Anyway I am not familiar with this issue, but perhaps you can restore your stock rom via flashtool, then call LG and tell them that you don't know why this happened Oh and modems are distinct from EFS I think (at least that's my understanding)
Your main problem will be the shipping though
I found this thread for the lg optimus G though - http://forum.xda-developers.com/showthread.php?t=2161498. Perhaps try PM-ing autoprime?
Same Problem
I also am in this EXACT same position. Still havent found a resolution quite yet. I am in correspondence with Shellnut the guy who actually wrote the freegee app that uses loki to flash cwm and twrp. He said that only cdma phones need efs, that the gsm phones didnt need it. This was new information to me. I haven't heard back from him quite yet as he informed me my phone wasnt bricked and that they would help me get back up and running. I know he is extremely busy. I have also been hearing that you can possibly use lg qpst to manually write your imei, looking into this now.
I would love to not have to take the risk of sending it in. Would love to just fix it.
i'm in the exact same position right now. Hunting the threads for a fix. I will be going back to Hong kong in 2 weeks time for 2 days, not sure if thats sufficient time for LG to get it fixed.
Hopefully we can find a solution soon!

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
