I have a Samsung branded YH 920 with a v2.05 bootloader.
The file name of firmware is FW_YH920.mi4.
I tried to make Rockbox run on my player by making a build using code in SVN.
After compilation, i unzipped the rockbox.zip on my player. Then i copied rockbox.mi4 to system directory and renamed it to FW_YH920.mi4
What is working : Display, Internal/External Storage, Buttons, building music DataBase
What is not working : playing sound, Battery Charging/Monitoring, some freezes during menu navigation
I'm a great newbie, but maybe can i help by testing new build.
Thanks for your work.
