Thanks. I will try another one when I'll buy it.
That used to happen to me all the time, with my old box and also with my Duo2 right at the very first time I've tried to flash an image. Also there was no "Update" message in vdf...
Then I read somewhere to format drive using HP Format Tool and it worked for me.
I recommend you try it before you buy another flash drive.
I never used Hp format tool - Allways used format command windows 7 or Vista or Xp -- FAT32 with USB Pen Drives from 2, 4, 8 an 16Gb, but allways sandisk or tanscend, never missed an update!
I've never tried format via command, always used windows 'normal' format window and never worked for me. The box reads usb, but update message never shows up and the stb just hangs there or sometimes continues to normal boot.
It's working now. I found my another USB drive, this one never let me down, it's 8GB Patriot Exporter 2.0 USB. The other two: Lexar 3.0 USB 32GB and SanDisk Cruze Force 2.0 USB 8GB don't work with my box anymore. Thanks for all your comments and help.
so if you are using 3.0 devices maybe the issues you have, is regarding this.
