hello, I have a problem with my LG K8 M200E. He suddenly hung in Fastboot mode. I can not do anything. I uploaded the ADB drivers, I tried to upload the file "laf, boot, aboot, recovery" but no results. All the time when I try something in ADB, I get the message "FAILED (remote: unknown command)". Please, help me save him. I can not enter recovery and download mode.
