I thought I'd give custom roms a try and now I'm left with this. Phone doesn't have a baseband, says "unknown" and my IMEI is blank. Now my phone won't connect. I didn't make a EFS backup. :-(

Your only option now is to restore to stock with Odin. It'll restore your IMEI and fix your baseband. Be careful of flashing roms to often or unstable roms. They can cause a lot of connectivity issues. Best to keep everything backed up if thats the case.

you can try to restore your efs folder and then install twrp on your device and install stock rom from sammobile
why i need to install twrp?
I really need help! I have been searching for months now on how to reset the imei number on my GS4 L-720 Sprint Phone. Some how I ereased the efs file and I have no back ups for it. I have tried installing stock rom, flashing it, recovering it and nothing is bring the imei number back . The mobile network type reads unknown, the network reads unknown, imei reads unknown. Help How do I fix this problem?
the Rom i flashed was to install CWM recovery on my phone but it was for the samsung s3 (T999v) model.
Unknown iemi,Unknown network,
Well, I had the exact same problem... and after rooting,, recovering, and all the other stuff out there in the web... NOTHING WORKED..... but then I found the strangest solution!! And it works perfectly, IEMI is back, and after 3 weeks of nothingness.. my phone is back to life and is reliable.
How I did it:
One night at sushi, i had a 100 USD bill and no pockets (running shorts), I then chose to open the battery cover of my useless S5 and hid there the bill. After closing the case, my phone starting beeping and buzzing, and is actually registering on the network...
WTH???
I remove the bill... and IEMI disappears... and phone is no longer registered on the network.
I compress in a post-it.. and Bam it works.
So basically, when applying pressure to the battery surrounding plastic frame, somehow, it revives the phone.
I suspect that some electronics got a bit lose after a whatever impact and that, when applying pressure to that precise location, the physical flash responsible for IEMI and baseband, connects back.
So before you waist your KNOX and time, try the above. A bit of paper pressed between the battery cover and the frame might just do the trick ;)
Cheers

That is just your case. Not even close to real problem. EFS must be restored.
every one is publishing problems but no one even reply ...if anyone knows the solution of all above then please provide link to get issue solved...otherwise this site is shit.
