Your problems are coming up because of titanium backup. Try using another backup program.
so i can't use titanium backup with this rom at all? seems weird. why is that? i didn't have any issues on an earlier build of MIUI.
I dont know the exact reason, but tb has caused a lot of issues with people that they say not to use it. I didn't use an app to restore my apps because my apps were automatically restored with i flashed the rom. Make a backup of your current setup and flash the newest version of this rom, not the one in this thread but the one at the top of the team d1-miui forum. And see if that restores your programs. if it doesn't start right away, download something from the market to get it started.
no disrespect to tp4, but this is totally wrong and the listed steps are unnecessary. titanium works fine.
