[Q] EFS backup restores but still get Not registered on network[

Hello all,
I have a Samsung Note 2 GT-N7100 Ver International
Using the N7100 backup and restore tool for windows made two backups and saved them successfully. I put N7100_Omega_17_XXDME6.zip Rom. using Clockwork recovery.
After installation i found that i kept on getting Not registered on network ERROR. I checked the imei and still corresponded with the one on the back of the phone. I then went to N7100 backup and restore tool and proceeded to restore. After restore completed i restarted my phone but i am still gettting Not registered on network

I have tried Ktools but the app said it does not know what phone i am using.
I am using windows 8
Kies 2.0
Galaxy Note 2 tool kit
Odin307
Does anyone have any ideas?

There's a lot of contributing factors that might cause this eg. Sim Card IC, ROM compatibility, Modem Issue and so on.
Try go to setting / more settings / mobile networks / networks mode and set to GSM only. Wait for two mins or restart the phone.

This looks like modem problem. Try to flash another modem, better via odin from pc

Sorry didn't work. Said the same message.

I was just thinking is there away to extract the files from the efs.img and manually paste it in to the efs folder? because every time i do a restore root explore shows no files in the folder? this is after flashing a new stock rom?

Ok what have you lost?
If you have the correct imei then flash this tool and it will recover your network.
http://forum.xda-developers.com/showthread.php?p=32338426
If your imei isn't correct either 0000 or 004499 then you need to flash your backup efs.img if you didn't back it up then the best thing is place the original stock rom and run triangle away and warranty it.

Problem solved
Guys I had this problem for about 3 months and today I found a solution to it ..so happy, so heres the deal ...my imei was not broken but I could not make calls .the error that it gave was not registered on network.i tried flashing stock rom , different modems , different roms but no succes until now.
So heres what you have to do
Install the latest version of miui rom .
Download the dmg1 modem and install it after installing the miui rom.
Then install the ariza patch and apply yhe patch that it has.make sure that you have internet connectivity while using ariza patch.after downloading and Installing the patch your mobile will restart and hopefully you will be able to make call.

i have the correct imei

CM 11 unknown baseband

I came over from the stock TW rom, I could not get signal. Baseband and IMEI information was null - despite using the clockworkmod recovery, I also have tried the modified TWRP version. I then tested the cm10.1, same issue. anyone has any ideas as to why this is happening?

That's because you didn't backup your efs!!! When you install a custom or whatever ROM you should backup your efs, which is the imei and WiFi and those.. When the efs is damaged by flashing a ROM, you can restore the efs backup you had and everything will come back to normal. I'm not sure how to recover your efs if u don't have a backup.. Research
Give me a thanks button if I helped

"Just sharing my experience in solving this issue. Hopefully it will help solve those who have similar issues.
I flashed a file which messed up my EFS partition. I had a backup and tried to use the available programs to restore my EFS using my backup. None worked. I even brought it to the samsung store, but they said they would change the motherboard and reprogram, and replacement and service would cost more than half the cost of a new N7105. I purchased the phone in another country. The people who had stores to repair phones gave up on my phone. They also offered to replace the motherboard for US$175.00.
My phone was originally under a DMB2 rom (from Singapore I think). I flashed a DMC3 rom, and used this for five months, until i encountered the problem.
I initially gave up and got a note 3. But i could not believe the phone was junk and people in XDA (as I observed) do not seem to give up.
After two weeks, i found the solution below, which brought my phone to working condition.
1. I flashed the stock rom N7105ZHDMI2_N7105ZZHDMI2_TGY from sammobile.
2. I flashed a pit file using Odin. The pit file is found here:
http://forum.xda-developers.com/show....php?t=2137008
This restored the baseband. But IMEI was no longer NULL. However, it was still 0.
3. I downloaded and used the EFS Pro from this link:
http://forum.xda-developers.com/show....php?t=1308546
Before using EFS Pro, make sure you dial *#7284# and change the setting of Qualcomm USB Settings to
"RMNET + DM + MODEM"
I will not hurt your phone if you do, but EFS Pro will just not work. If you don't do this, the EFS Pro will display "Phone not responding" or something similar.
NOTE: I couldn't find the option with RMNET, but i used the option that also had an "RM*** + DM + MODEM".
After the phone is read, change back the IMEI to what it was originally.
Dial *#7284# again to change back to "MTP+ADB".
It's all working now.
Hope this is able to help someone. Now i have two working versions of Note.
Thanks to the authors of the program i used, and the people who uploaded the files used.
Cheers!

THIS IS THE SOLUTION!
SELinux enforced mode stops radio signal from working.
No matter how many times i restored EFS, it wouldnt work.

part of what i did above was taken from this post:
http://forum.gsmhosting.com/vbb/f777/tutorial-galaxy-s3-backup-restore-imei-without-root-1513909/
take note of the following line:
*If you are running a aosp rom (cm9,cm10,aokp etc) you can use the diag method described HERE"
this might help you also because you are using CM.

[Q] No Imei and "baseband unknown" Please help! Really weird!

So, this is a long process I've been through-- First thanks so much for just taking the time to read this and any input would be awesome
I tried to flash a new slimkat 4.4.2 rom today and it flashed fine came up had service all was well except I think i did it as a "dirty" flash. I don't want to think any errors possible would be from that so i immediately did a "clean" flash and wiped everything except external sd-card in TWRP
Rebooted and noticed i didn't have any signal or data. First thought was modem so I started flashing MJ4 and reboot, nothing, so I flashed MK6 and reboot, nothing, so i changed to CWM recovery and flashed them, nothing, then at this point i just want a phone back doesn't even matter so i always seem to have several ROMS on my phone so i flashed another Sky Note 4.3 and reloaded nothing... So i started really wondering now and looking at my baseband to see what it said and noticed "Unkown Baseband" and Imei "unkown" (All while at work) So I came home did a little research while trying various other roms and none worked. So I read one way is to use Kies and do a "firmware upgrade initialisation"
Now it rebooting and completed going back to 4.1.2 CAMA4 and i still have nothing.. So I flashed UCALJ modem (Which should work as well) and I still have no data or signal because of unknown IMEI and Baseband. I don't really care about using triangle away or not, but i can get around and flash roms and everything thats what I don't understand.
Oh I did use CF-autoroot to install TWRP to install the modem as a .zip
Any ideas I would love you forever!!!

Lesson learned... no backup

I'm going to try and repair (backup and re-put) my EFS folder there, but how do i tell if its a complete EFS folder or if it is damaged? On the note 2 ATT is there a way to manually put in your IMEI? or reasons why this couldn't be my problem please

Last time this happened to me, a very long night, I had a guru on hangouts with me and we tried everything we could think of..
Only thing that got me back was a restore of an old backup, as a wild ass last resort.... Lost my mind when it worked
This problem is not weird, unfortunately it's common.
Starting surfing for your error and read read read.... I've had a long fricking day ..
Like a maniac I'm trying to port over a 7100 ROM.. I get that error also.
Only thing that gets it back is restoring a backup rom that had an efs backup in it.

In my EFS folder i can't find any .nv_**** files so I'm assuming they are gone and I don't have a back-up. I've been reading and reading with nothing coming out of it other then how to fix it on alot of other samsung phones. I can't seem to find a way to re-build and manually enter my own IMEI (because i know the IMEI) Driving me nuts!! but thanks for your reply

EFS folder anyone?
Any chance i can get a copy of someones EFS folder so that i can edit the .nv_data and add my IMIE? Please of a ATT Note 2
Thanks so much and just PM link

Sadly no...
It is both illegal...and unethical for someone to give you a copy of an EFS folder...
It contains the user data and carrier information for the device...making the folder private...and unique to it's owner ....g

I have done official firmware and over odin and before that Kies recovery. Also, knew it wasn't smart but didn't know it was illegal.
Any idea's for programs that will scan for deleted folders? or other ways to re-build EFS or .nvdata?

I was going to try this but didn't have to because I found a backup with my efs. I was going to try putting a new sim in and see if phone would see it and rebuild.
Actually was going to pull the sim out of my wife's note 2 and try it.

So I tried from my wifes sim today with no avail. Still don't have my phone and wondering if there is any way to recover it? Do i try to set it back to stock everything fix the flash counter then call samsung? I don't think its under warranty anymore since i've had it for almost 2 years. I know its a long shot but I wonder if taking it to one of those "cell phone repair" places would be any help? I'm out of options and actually had to drop back to my old HTC Inspire

Yea, the sim deal was to simple to work...
So never heard I don't think. What were you on before you flashed slimkat? Did you do the 4.3 OTA update?

Have you tried flashing an original rom with the Pit file? That's your last resort, EFS is unique to each phone by using someone's else's this is illegal as your modifying the IMEI. I've had efs issues in the past but always had a backup to hand. Try flashing everything with a pit file if that doesn't work then you will have to take it in for repair, Samsung official could do it but don't know what they will charge as it's out of warranty or maybe a local phone repair shop could do it or someone with jtag services can do it perhaps too.

A couple of other people are having worse problems like not being able to flash a recovery in ODIN or a ROM saying it can't read partitions. That's a good choice for a PIT flash.
But I'm reading and reading and everything is saying, yep that will work.... IF you then have the efs backup to restore

Thanks so much for the help!! I'm just worried that its not going to fix it and only make it worse possibly. I can't find how to pull my PIT file to analyze it so my next option is... Call a professional tomorrow... I'm going to call because apparently a "Z3X box" will fix my phone in like 3 minutes. I will post back though letting people know in the future whether they can or not. Because of legal reasons I don't know if they can even write my own IMEI back to the device. Will post back though regardless after tomorrow when I call them.

This happened to me a while back and I just flashed back to stock using Odin and all was fine

GREAT NEWS!
So I got desperate and realized this was going to take a professional. I called around to my local "cell phone repair" shops that really only know how to change the screen and asked about recovering the EFS file. It started out: "Hi can I talk with someone knowledgeable about the Android file system?" and every time the person said they were an "expert" So I said "I deleted or corrupted my EFS file and I need a repair for it" and EVERY time they told me they had no clue what I was talking about. I read and read everything I could find on the internet and most pointed me to some international "send you phone here" and of course I'm very skeptical of shipping my phone just about anywhere. So I found a person in the US at mobiletechvideos.com and looked him up with the BBB and found reviews from multiple sources.
I can say mobiletechvideos.com is legit and awesome! Josh fixed my phone and repaired the IMEI in less the 10 minutes remotely. I have my note 2 back! Please do not hesitate to give this guy a try he is legit and really down to earth guy. This thread can end here because whatever he did I have no clue but it worked!
Also a lot cheaper then I though it was going to be

[Q]IMEI lost after flashing cm10.2 and can't be restored

Hello everyone. I'm using the Note 2 lte version(N7105) and yesterday i flashed my phone from stock 4.1 ROM to CM10.2 (latest stable version found on CM website). Everything worked fine expect that my IMEI got lost, but i still can make phone calls and send SMS and the base version is displayed.
The system information displayed like this
IMEI
0
IMEISV
01
instead of displaying 0049***** or 0000000000
and if i dial *#06# the imei is 0/01(instead of a series of 0)
Here's some way i tried to fix this.
!. Restoring the EFS backup and flash back to stock 4.1 rom.---DOESN'T WORK STILL 0/01
2.Flashing a different baseband ---DOESN'T WORK STILL 0/01
2.Using EFS Pro (Qualcomm nv tools) to recover my IMEI under stock rom ---DOESN'T WORK (when i click the connect button the window freezes then two windows pop out saying connection is lost and can't send SPC)
3.Using a nv_data.bin generator to generate a nv_data.bin which contains my original IMEI and copy it back to EFS partition---DOESN'T WORK STILL0/01
i've been working on this for a whole night and i still can't solve the problem. Could anyone please tell me what should i do? Please.
:crying::crying::crying:
Thanks in advance!!
FYI my efs partition file structure looks like this:
/..
.flies
bluetooth
drm
FactoryAPP
imei
wifi
00000000.authtokcont
gyro_cal_data
h2k.dat
wv.keys
and nv_DATA.bin can't be found.

back to stock in different regions, if not work, try flash some custom roms changing patched modens and kernels

Deleted EFS folder.

Hi everyone,
I'm fairly new to the android section and I recently received a phone from a friend who deleted his EFS folder. This phone is a Samsung Galaxy Note II. I have tried various different software to restore the efs folder and unfortunately no success. Is there any possible way to restore it without sending it to Samsung?
Edit: Yes, i have flashed the stock ROM, still no luck!

Have you tried flashing a stock rom. It might recreate efs folder.

Done that, no luck.

Also have this problem on my Note 10.1 3G although I did not remove the efs partition. It just randomly started bootlooping while it was charging and I was gone and the recovery said it couldn't mount /efs from that day on. Kinda sucks since I now have a generic IMEI and the battery is draining from cell stand by, even when it's in airplane mode.

Bro I could hv done smthing f i ws dere. So nw i suggest you is flash philz recovery, go to factory reset and do a wipe to install new rom. Now install stock rom of your region from Odin. Then send it to the service center.

aw man that sucks! I'm probably going to send it to Samsung, tried absolutely everything to repair mine and no success. Hope you get your problem fixed mate!

So what brand are you using ? N7100/N7105 or anything else?
