Thank you!
I've been trying to troubleshoot issues I've been having with my H320 and an SSD. I've tried different builds of Rockbox and have the same issues. I've read many posts here regarding the H300 and SSDs and the only thing I haven't haven't tried was the different bootloaders.
In trying the other builds of Rockbox (development, current, archived), I haven't seen a bootloader installed other than version 5. Now, I attempt the hard way. :'(
