If he was trying to install a custom theme, then the flash0 is messed up with the edited files from the theme.
oh!, ok, you have no access to flash0
then your only option is to use pandora's battery and run despertar del cementerio v3 or v4, as it will format flash0 and install custom firmware again
(BTW tell him not to mess with flash0 if he doesn't know what he's doing, or has a pandora's battery)
