using root explorer, goto /system/etc/init.d, create new file name it as "75sdcard". paste this script and save. set permission to 777 (rwxrwxrwxr using root explorer). then reboot.
let see if it remove your soundbug.

Thanks in advance

You got that sound bug? I thought it only resides on slower CPU phone :/ I don't get a sound bug with 2048 kb set (only when the CPU is too stressed, some audio bug may occured, but not as bad as my old X10 Mini Pro)

Some general rule of thumb, SD class 6 and/or faster, 2048 kb and up. SD class 4 and/or slower, 1024kb and less.

Hey sirkay, you need to add some caution though when flashing these kernels. It seems that the kernel.is preloaded with busybox and root, but not the newest one. So it was lagging my phone (sudden freeze). My solution is to uninstall and reinstall busybox from market and fix root by updating it.

Does this work only on ICS? Can it be used on GB custom roms like rayonium?

Sirkay, You just WON.... ...Awesome...

Touch Recovery ?? .... You didnt let Ray users bow to Arc users... Thumbs up mate...

Btw.. Is there anyway you can remove that Back and maybe Menu button...?

Not necessary but just asking coz ARC users have the benefit as they dont have touch keys but we Ray users already have touch and Menu back button.....


EDIT: Sorry That circle button is for click.. Thats Great.. I always hated pressing home key for a tap... I guess Back button is fine to remove...

Thank you for a great works. Working perfect here..init.d now working..

none

Sirkay, I cant mount card in Touch recovery...
