Format USB pendrive on FAT32

Put both files from here on a folder called boot inside of the pendrive

put the pendrive on port 2

turn on the nas wolding up the reset button for at least 40 seconds

look what addresds it will show up on your network

it is booted in safe mode, you can now upload a original .bin file
