(I don't know whether anybody else posted as I am a newbie) I encountered "zero memory" issue if I flash custom ROM over another with "onepackage" and factory reset doesn't help. Now I found a fix of this issue, and this should be done if you want to flash custom ROM over another. Download and flash BH-MAN Warheads ROM http://www.4shared.com/file/nFe93F45/BH_MAN_WarHeads.html Make sure you put in the components correctly. After md5 check has completed, you can flash and take a little break. Once you're in the standby screen on the phone, you can turn it off and reset the Odin and select the ROM and .ops file along with the ROM. Mod: please put it sticky if you feel fit.
