is there any possibility to boot the phone in fastboot mode??

Hello.

"download mode is disabled by kill switch" error means that that Download/Emergency Mode is blocked by McAfee application. The problem can be fixed by complete removal of McAfee application.
Unfortunately we don't have Full Flash of D855 at the moment.

if i will make backup from another working phone and then write to my phone will be ok?

[Octopus box]

Yes, writing of a Full Flash of another, correctly working D855 should solve the problem.

Try to make Dump NAND via Octoplus/Octopus LG Software (select *.bin extension for output file), then try to write it via Medusa Software.
