I have an LG G2. When I connect it via USB to the PC I piece or 10 drives go format. Whats wrong

[AC Question]

The drives were protect. On the phone i can nothing. Because there is something wrong with the update. There is no contact with the PC

Was it an over the air update? If so, bring it to your carrier and ask them to please fix what their update broke. (In most countries, the law is basically "you broke it, you own it". IOW, they assume all liability for sending you an update.)

If you downloaded an update file and installed it yourself, you'll probably have to find a way to force it into download mode (you can't boot from the SD card you can't put into that phone) or find a JTAG service to reflash the ROM.
