I was updating my routers/switches, and I noticed that an RB3011 was still on RouterOS 7.10.2. I attempted to use the automatic updater, several times, but it wouldn't update...stayed on 7.10.2. No error messages that I could find in the logs; the update just wouldn't take.
I then got the bright idea of downloading NetInstall and attempting to install 7.14beta directly. After some fits and starts I finally figured out how to put the RB3011 into Ether Boot mode, connected with NetInstall on my Windows laptop, and ran through the procedure. It said that it was successful, and I attempted rebooting the RB3011.
However, after that I couldn't get anything useful out of the unit. It stays in "Ether Boot" mode, and I keep getting the error message on the small screen, "Kernel Loading Failed." I tried downgrading the RouterOS version and doing a hard reset, both unsuccessful. I've now pulled the unit out of my network (leaving a computer and a NAS bereft, and I'm wondering what I can do to try to salvage it?
