If you flashed uboot you can put one of the later firmwares with wifi enabled on a FAT formatted flash drive, insert it into the dongle and turn it on while holding the reset button. It might take a few tries but eventually it should reflash it.I followed these steps, and have been met with no success.
The payload is not injected on boot, and the SSID is not being broadcast anymore. I seem to have simply bricked the tiny thing. Any ideas? I don't have an ethernet port and don't really feel like dropping cash on an adapter on something that might not work.
