ok i solved that
i searched in google for sph-l720 gsm unlock and i found in xda-developers the solution
After installing the OTA update of MIUI7 my Redmi Note (4G) Single Sim says "No SIM Detected" and I also can't connect to WiFi. My phone doesn't show any IMEI number or Infact it doesn't show any kind of phone data including MAC Address and all.
I thought the OTA might be buggy hence I rooted my phone, installed TWRP and flashed CM13 by dior. I thought by doing all this my problem would be solved but it isn't.
Anyone else who's faced such issue? Is there any solution to this?
Thanks.
Help please!!
Same here!!!:crying:

I am having hell of problem with my At&t G2 D800. For last 2 months I had issues like INVALID CARD every time I restart/Power off my device.
From last week it got permanent and now I have IMEI=0 , Unknown baseband and Service disabled.
Don't have backup of EFS
Tried Flashing Stock KK Firmware but no way.
Tried to fix IMEI with EFS Professional and it says succeed but after restart its still same.
Can any expert help me or anyone can say is it possible to get my phone fixed? Or should buy a new one
Successfully restored the IMEI and baseband using this http://en.miui.com/thread-243496-1-1.html. Now everything is OK.

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..
