Hi, I am trying to upgrade my H2S from Wooshbuild version 3 to version 5, however, i have tried doing it the standard way by uploading the h3 folder to a usb and inserting it into the front panel, then back panel. I have tried doing this a thousand times, formatting my USB to FAT32 (i have used 6 different USB's) without any luck. I am pretty familiar with the ZGemm boxes, as i have been using them for 2 years, however, the box does not want to recognise the USB and flash. It is not the USB because I have tried many different ones. Is there another way of installing version 5 or would i need to delete version 3 from the box and reset it to default? Many Thanks, Mrteddy
