good day guys, just want to ask if we could rockbox the xuelin ihifi 770/770c and 800. this daps have great potential but the crappy FW is holding it back. i've seen that there is a rockbox FW for the 960 and the 760. i hope we could port a better FW for this daps to unleash its full potential. i don't have to proper education to code this kind of stuff. i hope you can enlighten me with this. thanks .
