Hi, i've tried to set the auto rotate for my firmware v.30 to automatic, however it din auto rotate, may i know is there anything else need configue?

also after uploading my firmware, i've difficulty to restore previous messages and application back but it'll run until 50++% but fully uses my CPU and memory spaces and showing me error command.

and if i've updated to v.30, can i reinstall it as i chose the wrong region as well... sigh...

Million thanks for the info given
