give back my original sound driver

[mackydon]

hello guys, I've w810 with spec:
-R4EA031
-cid = 50

I've flash my w810 with
W810_R4EA031_MAIN_GENERIC_HN_RED50

but the original firmware is:
R4EA031 MAIN CHINA HN RED 50

now, my w810 sound is terrible. I want my sound back!
oh, by the way the camera isn't good anymore.
I think its better when it's original....
help me, what should I do???
give me a tutor or a link guys. thank you.

Here is a link to some excelent sound drivers(acoustics) for w810, these are better than the generic ones. louder and clearer
Just upload it to ifs/settings/acoustic on your phone using the "FSX" function on xs++
