Do you have a hard drive or another USB stick plugged into the back?
If you do unplug it and use the front port to try flashing again.
Have seen a few posts where having a USB stick or drivevplugged in the back stopped the box flashing at all
Thanks for all the advice so far from everyone.
I've had enough for tonight (second day of trying to resolve this).
A parting question is it worth me downloading the sucumnsee stuff?
Other option is to flash BaseBuild from the USB stick via the menus to flash locally. I don't know where it is in Vix though. Probably in the system menu with everything else lmao
With openATV it is Blue button -> Flash online / Local - and then select device and navigate right through to the rootfs.bin file in the h3 folder.
It won't solve why you can't boot from USB though.
For vix it needs to be in media/hdd/imagebackups in a zipfile then menu, setup, vix image manager blue to restore
You can just put the Woosh basebuild zip file in imagebackups folder and flash via Image Manager in ViX.
In the imagebackups folder on the hdd you just need BaseBuild-v4.zip - Leave it zipped, don't extract it.
Go to Menu > Setup > Vix > Image-Manager and you should see BaseBuild-v4.zip.
Highlight it and press the blue restore button.
(on a side note did you try the partition wizard method in the 'formatting drives pdf' in my sig? I've never failed to flash from usb using this method)
I've just done a guide on how to prepare a usb drive for flashing using BOOTICE, which is a free Windows utility and needs no installation.
I've tried it on 11 different USB drives and they all worked after using this method.
