Hiby RS6

Waiting for some NPAudio hardware mods on this one. Purchased the RS6 and for me it's a keeper. It offers a different flavor than my WM1Z but female vocals like Norah Jones are sublime. It lacks battery life but I'm certainly intrigued by my first R2R DAP.

Some pictures:

Me too 🤔😂

Not much room to work with but I managed it the tiny ZX300

** Root NOT required for this **

Make the RS6 even faster ! and have more battery life !

Uninstalling around 60 apps they aren't removed from the RS6 rather uninstalled for the default user i.e. us
They can be reinstalled, they also come back after a factory reset.

You will need to enable Developer Options
(clicking on 'Firmware Version' in Settings, System and About device a good few times)

You will need to enable usb debugging in developer options
You will need ADB on your computer to connect to a console session on your RS6 via USB

If you want to reinstall anything for example: Via Browser and the Desk Clock use:

cmd package install-existing --user 0 mark.via
cmd package install-existing --user 0 com.android.deskclock

Hiby configured the kernel odd.

I found for Audio apps only CPU cores 1-2 can be used whilst everything else has CPU cores 0-7
I changed it from only 2 cores to all 8 and can now bring the cpu clock down to the lowest and still upsample to 384khz whithout a glitch in neutron. This great news to toggle great battery life on


i'll be checking the other rooted daps for this

DX300MAX, DX300, R8, R6 2020

Hello!  Would you be willing to share your kernel changes to me via PM?  I won't release it.

Your work is awesome BTW!

@npaududio,

This is great work, thanks Bro.
