So I decided to use my original ROM .img files that I backed up previously and built a CWM flashable zip from that. Only I substituted the recovery.img for the one in RK30GENERIC_CWM.zip so that I don't lose my CWM.
I rebooted, and then I get stuck on the four Linux Penguins. So maybe I'm not building the flashable zip right. I don't know...

Since I did a backup in CWM before I decided to go on this crazy endeavour, I decided to restore the backup. System up and running again (of course, without the wifi and bluetooth).
This sucks.
