i check again the source code, i think its ok, only one thing what i noticed that.
im lowering some voltages after the jan09 version, and more lowered after the jan19
so im back to the voltages what i used in the jan09 version.
test build link in the OP
separate update for wajkiui because this rom have many init.d script and my kernel installer will erase all of them, its not good. so the wajkiui installer just replace the tweakaio script, and install the modules.
bravia engine, and other stuff is already in the wajkiui.
tested with wajkiui 2.1.20 and temasek cm7 kang49
booth working fine, wifi, mobile network, everything.
just dont forget to flash the right ril after the rom install!
