[Sansa Clip+] Rockbox and original OS wont open

[jeffmangum]

Its been months that my rockbox clip+ is acting up. Sometimes it hangs when i open it, and sometimes it jsut doesnt open at all.

I dont remember what i did that it became ok again but i think i deleted rockbox then reinstalled it.

But now i dont know what to do.

How do i properly reset it to a state when i bought it?
