Bricked LG G2 with access to recovery - TWRP 2.6.3.3 doesn't support OTG?

Hi Guys,

I have a problem with LG G2 - I have access to the recovery TWRP 2.6.3.3 version but it doesn't support OTG pendrives. How can I install ROM without access to any OTG pendrive?

I can't also enter to Download Mode.

I was looking for any info in the Internet but without success.

thanks in advance for help
