[Q] full wipe problem in ROMs with preload apps

As JB roms becomes so popular and so the usage of preload partition in rom cocking, I have noticed the following problem when I do full wipe to the device (factory reset), the phone will end up with boot loop..
This is only happened if rom uses preload partition during cocking!!!

Any idea pauls how to do proper full wipe without installing the rom again in this situation???
