Hello! So yesterday i tried to unlock bootloader then something went wrong, after i restarted my phone (LG g2 mini d620r) i saw that screen was rotated by 180 degrees and the display quality was pretty bad. i decided to install new firmware but i can't seem to get in download mode because the hotkeys isn't working. I even tried to do it with ABD. The thing is that my phone is functioning properly except the screen is upside down. Please help!

-download mode don't work
-recovery mode don't work
-factory reset mode don't work

Thanks!
