d) After connection, the STB checks the version number of the software in the remote to
confirm if this is the most updated one.
e) If any software update is needed, STB sends the command to the remote to move to
Image A. Commands are defined in the Appendix 1 - Attribute Table for OAD.
f) After receiving the command from STB, RCU needs to re-boot in Image A.
g) After finishing boot-up process and connecting to STB, the software update starts via
OAD.
h) If the software update is made successfully, the remote reboots in the image B.
i) If the software update has failed, the remote reboots in Image A and retry it from step g).
