I have recently acquired a tenda 3G150B device, and after some playing (very short really) I've managed to turn it into a brick.. really easy.
Here's the inside overview:
3G150B 150Mbps Portable 3G wireless Router
My questions to the experts:
-Would I be able to recover this brick with a re-flash?
-Would I be able to reflash with OpenWrt
Due to tenda's great support, they preferred to return the money.
