This is not a Linksys firmware. It is a third party firmware, so it is certainly not Linksys' fault. It most definitely is the consumer's (op) fault. As for returning it, I would think that is very questionable. That is strictly my opinion. Yes according to CC's return policy it is within his right (OP) to return it. If it were me I would not. See I8er's comments. After all when the op tried to install the firmware he/she agreed to take the risk of "bricking" his/her router.
