While attempting a normal upgrade to an RB532 running 2.9.14, we copied the new firmware (2.9.27) to the the router and then rebooted and now it won't boot at all. We are not sure what happened, but we ended up having to pull the unit after multiple attempts to fix the problem with Netinstall.
Here's the scenario: netinstall says upgrading, then ready, but then it just doesn't do anything. We've even tried upgrading the BIOS first, and still nothing, has anybody had this happen before?
Here's what happens...
