Hello everyone.
Yesterday I tried to flash my nexus to f2fs. After that I wanted to go back to the stock, but forgot format filesystem to ext4 and run flash_all.bat.
Flashing was stopped on system write with error: "Unknown chunk type". After that i can't open recovery or turn on phone.
On 4pda i read, that bootloader reopen can help fix this problem.
When I flash new boot, nexus was died.
Can you help me?

What happens when you hold down Power + Vol down keys together? Hold them until you feel a vibration. May be the battery has died? Keep it on charge for an hour and then try to enter bootloader?

nothing happens. When I put the phone on charge, it starts to warm up a bit in the camera, but even the display does not light up.
when i connect the phone to computer, it is defined as qhsusb_bulk or unknown usb device

Your memory is no longer accessible unfortunately, you most likely need to have it repaired (new motherboard) :crying:

If all the key combinations don't work, them your device is done for! Since it's totally dead there shouldn't be any problem to RMA it! Good Luck :)

Press and hold volume up while you connect usb cable to pc.
can you see download mode on device screen?
if yes read this thread entirely http://xdaforums.com/showthread.php?t=2515760

Edit: try this also:
connect your phone to the pc, open device manager.
hold your power button until QHSUSB_BULK disappears, then in that split second press and hold both volume key while you still press the power key. it may end up into the second bootloader
