Well it wasnt bricked just being stubborn as always about
entering usbboot mode. Anyhow I reflashed with the latest bootloader supplied
by qi-hardware.com. It works fine, however Im still not able to do [U]+POWERON
and reflash.
It enters usbboot mode alright but when running usbboot -c "boot" I get
the same issue as I had earlier(see log below).
I thought it might be due to the stage1/2 files so I downloaded and compiled
xburst but getting same output. I earlier had updated the usbboot tool with same result.

I thought this was fixed? Or did I miss something?

For me personally (with major usbboot troubles) it would simplify my
life a great deal.

Best wishes
