Magic DEVICE Imei and Baseband restored but sim card DIE
You have to reflash a GB-Rom,i.e. JVU. Then everything will be ok. And after that flash a ICS-Rom which not makes disappear the IMEI and then, without wiping you may flash this special ICS-Rom which caused that issue. Now everything should be ok. That was the experience I have made.
Hey Guys I need some help with Nv data (EFS )
The NV data baseband is I9500UBUAMDE nonetheless my firmware baseband is I9500UBUGNJ1
I think this is why my phone do not have a stable conection with cel-towers...
So I need to know, how to update the nv data without corrupt it?
Kindly regards,
AG
Just flash a stock ROM using Odin. This will ensure that the bootloader and modem match.
Already did it some many times... Without results...
The phone is missing the imei and MAC address?
No one is missing...
Phone signal Goes out and in.
However while the phone has signal. I can call and navigate on internet..
Do you need the efs folder?
If the phone has an imei, then it seems like the efs folder may be fine and something else is happening.
So flashes are successful in Odin?
Could the phone be blacklisted? Was it ever dropped? Tried a different SIM card? Tried our SIM card in another phone?
Ok, I have to be honest... I was on 4.4.2
I try to use galaxysim unlock. However EFS was v2 and I restore a v1 efs folder in order to unlock the phone. It works. However after upgrade to 5.0. It start to fluctuate the signal...
Note: v1 and v2 are versions in matter of security of the EFS folder...
That is how this how begins...
Did you restore the original version 2 efs? Do you have a backup of the original efs? If not, I'm not sure if an nvwriter will help.
I think I do not have one...
What should I do?.....
I'm not sure what to suggest. Maybe Google nvwriter and see if it works with your phone.
today i flashed the xxx rom and flashed the ap file via odin all went well and device was working but i suddenly realized my network was gone.under phone info the baseband was unavailable and my imei was gone.after alot of searching i found a site where a efs+nvdata.tar file was uploaded.i flashed that file and i got my imei and baseband back but mobile networks is still unavailable. ......when ever i boot up the phone it shows a unlock sim message........i tried kies,efs professional but nothing works.i tried to restore the efs.tar.gz file but it isnt working.i noted that my imei after flashing the file matched my phone,but the s/n number doesnt match but i dont think it matters as long as the imei is ok.PLEASE HELP ME,if a efs backup will fix it i beg anyone to send me a backup or tell me how to fix it..please:crying::crying:

Do you a have a efs.img backup ? Or any kind of IMEI/EFS/RADIO backup ?
I had the same problem I flashed the stock ROM and somehow I lost my IMEI info, I tried everything and I was even thinking about buying a z3x box but then I decided to do a very risky move , I completely deleted all the EFS related files/info and reflashed again but now I was not able to boot because I always sent me to recovery mode saying that :
"E:Failed To Mount /EFS (invalid argument )"
Then all I did was installing TWRP and rooted my SM-G935F and then I placed my efs.img backup on my internal SD CARD and went on recovery launched the terminal and wrote this :
dd if=/sdcard/efs.img of=/dev/block/platform/155a0000.ufs/by-name/EFS
Then I wrote reboot and it finally my phone was booting and I recovered my IMEI and was able to use my phone normally.
This only works if you have a backup of your EFS, and even if you do is risky , but I did it because I lost all hope and was accepting the fact that my phone would just become a useless wifi only device .
So there is not a fix yet for this problem ?
I have a problem on my s7edge instead. If i have valid imei i'am almost always in emergency calls, and when the signal comes back does not go into mobile data connection. With the wi fi no problem.Can someone help me i'am going crazy.!

IMEI, Network Signal and Baseband is misssing
Hi
I am ready to donate if any expert can help me to restore IMEI.
I am using SM-N9500 samsung note 8 model - hongkong version, i frequently change the roms.. when last time i tried to install a custom rom i lost IMEI. i am getting error like IMEI-unknown, baseband- unknown, no network and sim cards not working..
i tried installing stock rom, custom roms, it was installing successfully but only baseband, signal and IMEI are not working. i didnt even back up my EFS folder. So, kindly help me to get back my IMEI.
I have installed stock rom, still no IMEI. now i rooted my mobile and taken EFS backup. is it enough? if yes, pls suggest me the next steps. I also tried installing combination firmware, though is not working, installation was successful and also i am able to see the factory binary logo, after which it will switch off automatically and boot loops. everytime it will open factory binary and immediately it will switch off automatically..
