did you try to convert to ext 4?
if so thats the reason
you need to get busy box off the market before that conversion or that happens
version 1.17.1 by stericson
when u go to install it it will say 1.18.4 with a drop down box
choose the previous verson which is the one listed
install that it will reboot
u should get stuff back and ext 4 will disable if you want it enabled
make sure ext 4 is disabled goto your sd card *u mmay have to use a pc for this part* wipe the voodoo folder off the root of the sd card
stick back in phone
reboot into cwm red by vol up down and power button hold tell the screen cycles once then let go your good
goto advanced
make partition 2048
let it do its thing it takes awhile
reboot when done linda will convert and all your apps will be back
ya sorry for the convaluted install but its beta we work with what we can
