Hi everyone!
So, I flashed Android severals days ago.
Then, I booted into dload mode, took backup and went back to WP.
I unlocked bootloader and booted into mass storage mode to restore Android, but HDD Raw Copy reported an error "Can't write to device, aborting"
Then I rebooted, phone vibrated and then black screen.

What can I do?

Please clarify what you are trying to do. The backup that you made was the backup of the phone while it was running WP8 or running Android? Which OS do you want on your phone now, WP8 or Android

Also, what does Device Manager show in Windows when you plug in the phone now?

I did backup of Android. Device Manager showed device like Unknown USB Device (Device Descriptor Request Failed) with code 43.

Afraid I haven't seen that error 43 issue before. My second L521 does the "Black Screen - Vibrate only" but it shows up as "USB HID Input Device", and I wasn't able to fix it.

WinDiskImage may only work for backup/restore of the WP8 partitions.

I checked again, and my phone also shows as "HID-compliant vendor-defined device" and "USB Input Device"}
Hardware Ids is: HID\VID_05C6&PID_F006; USB\VID_093A&PID_2510&REV_0100

PID_F006 HID usually means battery is empty.
Try connecting the phone to USB with battery removed. If it shows up as PID_9008, then bootloaders are dead, otherwise it's something different.
If in 9008 mode, you should try WPInternals' Unlock Bootloader option.

Without battery, it doesn't work at all.
I also got second battery, which is charged, and it also doesn't show up with that battery.
It seems that only with dead battery phone shows in Device Manager

So, I booted into ubuntu and connected device.
dmesg shows:

Dead Lumia 1020 while bootloader unlock WPinternals 2.3

PID_F006 HID usually means battery is empty.
Try connecting the phone to USB with battery removed. If it shows up as PID_9008, then bootloaders are dead, otherwise it's something different.
If in 9008 mode, you should try WPInternals' Unlock Bootloader option.

Dear in case bootloaders are dead, the only solution would be JTAG right? Just to confirm
