Ok,but I make mistake and chose format all+download in SP flash tool and can't backup nvram.If someone have this phone please backup and send me nvram file (about 5MB). 
You can make backup nvram with this simply guide 
Start address for nvram of Doogee S55 is 0xa700000 and lengt is 0x500000.

If you formatted then you'll need a full stock rom, not nvram alone. ...unless what you're trying to say is that you've been able to fix the phone but are having NVRAM issues.
If that's the case, what's the exact NVRAM issue you're having?

I have stock rom but without nvram file.Before flashing this stock rom I make nvram backup with wrong physical_start_addr: 0xa380000 and partition_size: 0x500000.I am download stock firmware for S55 20180707 and see in scatter file for nvram address begin: physical_start_addr: 0xa700000 and partition_size: 0x500000.I flash this stock rom with my wrong nvram backup and after that my phone does not have any imei number.I think I need only nvram file?

You can fix null IMEI using the methods @ https://www.hovatek.com/forum/thread-116.html without NVRAM file.
Does the phone have a valid baseband? (Check settings>about>baseband)

Thanks for answer but for now i have new problem.Trying too many times to fix my problem,tonight I am brick my phone with SP tool option 'format whole flash'.When I am try flash firmware again with SP tool but only get this info:

MTK USB Port (COM37)
and ERROR:STATUS_DA_HASH_MISMATCH (0Xc0070004)
I can't flash preloader again.Do I must remove battery?S55 have non removable battery.

Try disconnecting/reconnecting the phone's battery then try again, you'll need to disassemble the phone to get to the battery.

big mistake! i believe you'll need an auth file to fix this
does your firmware contain any efuse**.xml file?
