RB433UAH => 6.35.2

Heya guys. I got old RB433UAH. It runs 6.21.1 RouterOS with 3.24 firmware. I’m trying to upgrade my RouterOS. Mikrotik downloads latest patches, reboots and restores to 6.21.1 RouterOS. What’s my mistake? What can I do to upgrade to 6.35?

Drag and drop the packages you want to install into winbox and reboot after the transport.
