Everything was fine until I decided to uninstall ML.
My computer isn't properly reading my SD card so I thought I could just insert it in my phone and erase the ML directory and files leaving just the pictures folder.
When I tried to turn on the camera, nothing happened.
What can I do?
For the next time: Reading install instructions in Nightly Build download page with care and Install Guide and FAQ, too. There you will be find a warning *not* to do this because your cam will get stuck.
Remove battery. Format card in cardreader. Format card in cam. Start install from scratch.
