I installed A9LH on two N3DS 11.0, using System Transfer / DSi Downgrade. While installing these, their speakers became distorted (either after the firmware downgrade or the CTRtransfer, not sure which), but they became fixed on the last step (firmware update / dspdump). Modded a third N3DS, on 11.2, using SoundHax. These speakers also became distorted after the CTRtransfer, however they never got fixed after finishing the full installation. I'm 100% certain I did not miss any steps (using the website guide). The speakers seem to only crack whenever they play sounds louder than a certain threshold, in most cases only when the volume is set above 80%. Is there any known solution to fixing this bug? If not, I'd like to try reinstalling the 11.2 firmware, so is there an easy way to do that? Or a safe way to downgrade my firmware to any level, so I could re-update back to 11.2 in system settings? Thanks.
