You have to reinstall Official lollipop
If you flash and custom rom that make EFS Backup automatically, for example Ozcan ROM, you have to search a folder with this name "efs_Backup" in your "internal memory"
If you have this folder and backup
Make this instruction for downgrade to Kitkat: Here
But if i go to lollipop also still my imei and Baseband will be unknown !!

No it's not so. Revert back to Lollipop and your baseband, imei will be recovered.
I have already experienced this, have been jumping between Kitkat and Lollipop since a week because of the same problem, I guess Lollipop has updated the EFS which makes Kitkat unable to read it properly.
Hope this helped you!
Unknown imei = go to lollipop, null, generic etc need a efs backup, however you can go to a mobile shop with a octopus box or something like that.

i9500
baseband unknown
imei null/null

Unfortunately in this situation there's not a lot you can do without an EFS backup. A service centre can fix it.

You need to flash NE1 or NF2 modem for quick fix...
If you have made a efs backup before previous flash you can restore efs.
