I went to the download page, selected rb700 series, clicked zip file, downloaded.
Unzipped the download.
Fired up winbox, dragged and dropped the files into the files menu.
Once the upload completed I selected the shutdown option.
Once the lights went out I unplugged it and plugged it back in.

Once it rebooted it just sits there and power cycles over and over again.
Holding down reset while powering up doesn't change anything.
Tried net install, held reset on bootup until act light stops flashing however nothing shows up in netinstall window.

Anything else I can do or at least where did I go wrong?

Alright I put netinstall on a different computer and downloaded the NPK file instead of the ZIP file.
I am now able to transfer the npk file via netinstall, it formats the HD, transfers the file, says it finished and i click the reboot button however the device never seems to come up, it doesn't deliver DHCP on ports 2-5 nor respond to pings on 192.168.88.1 from those ports.

Anything else I can try?

alright nevermind, by some miracle it started working again, wish I could say exactly what i did.
