Hi,

3850s come with a USB port (usbflash0). So, you can transfer files from USB to flash or from flash to USB and load it to your PC.

Hi,

There are several newer versions.  The latest (none Denali) version recommended by Cisco is                  cat3k_caa-universalk9.SPA.03.06.08.E.152-2.E8.bin

Hi,

If the file in the USB then you make a sure copy from usb0: drive to flash: and run install command.

Hi, 

You don't have .bin file on your switch flash so you have to download from Cisco website. As mention @Reza Sharifi recommended version is :cat3k_caa-universalk9.SPA.03.06.08.E.152-2.E8.bin

Go to the Cisco website and download the file from there.
