My IMEI resetted to null

I just recently updated to docs ROM and when i check my IMEI it displays null.
It seems the update or kernal update has resetted my IMEI.
I would like to know how can i set it back, because i know my imei number. Is there any command i can set it to the phone.
please help me on this regard.
it's solved. what i did is i flashed the CSC & Phone files back to DDJP6 version. So this helped me to make phone displaying the IMEI.
The issue was last ROM update made some problem so android/phone was unable to read the IMEI number correctly, thus showing null..
Now it's working perfectly..

Need phone file to flash
I've got a Captivate i897 (flashed as an i896) that my brother bricked and we had it JTAG flashed. It now shows IMEI is null when you do a *#06# and when you do a *#1234# it shows PDA file and CSC file but PHONE shows as "unknown." When the phone boots up it creates invalid files in EFS due to not being able to read the IMEI. If I change the nv_data.bin from another phone and set permissions and ownership it can then get a signal and make calls but still shows IMEI as null. If I reboot then it goes back to not working. I need a PHONE file to flash in ODIN to fix it I think. If someone can tell me what PHONE file to flash and if I can flash just that FILE to fix the phone.

Send it back to LG for repair. messing with the IMEI is illegal (short of backing up and restoring) and as such banned from the site.

imei null baseband unknown network unknown mobile network type unknown

my imei is null and my network wont work i want to fix this phone because i want to go to att and get a new phone and it isnt under warranty any idea what phone i should get too ...right now im about to unroot back to stock using odin and hopefully that will fix it but my buddy told me the efs files and folder are corrupted but they were working i was thinking it was a hardware problem because it has been working on and off for a few months a reboot would fix it and it would start working again now as of yesterday it stopped working no matter how many times i reboot please help i hope its something simple as flashing something through odin

@irfanbd94: You should have posted your comments to your thread instead of this one.
Take your phone in for service. Trying to transfer the IMEI of a defunct phone to your working phone is illegal, period. No discussion of how to do it is allowed.

please help me save my s5

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:
