this may help. it's my base for my personal rom.
so far this is a just a very slightly modified stock gingerbread rom.
system is deodexed, rooted, tweaked, a2sd enabled.
koumakernel and cwm5 preinstalled.
we can all thank Shabbypenguin, Koumajutsu and Hroark. a lot.
some of the build.prop tweaks that have been introduced are present already.
the only app i changed is the stock launcher. it broke when it deodexed so i replaced it with adw launcher.
a2sd is enabled by default so you can
1 format your sd before you flash it or
2 hold the vol up button as soon as 'Downloading...' disappears, enter cwm and partition your sd there
(be sure to have a backup of anything you want to keep from the phone and/or the sd card before you do anything!)
it will take a few minutes to boot the first time but be patient, it always boots. i wiped /cache and /data just before i packed this so it rebuilds on boot and avoids errors like google auth. also adw launcher will force close one time on first boot. and then it's stable. let me know if there are any problems i haven't found yet.
