Unbrick the cam

If the camera no longer starts (with or without hack), wait before throwing it out the window. Probably the user partition is broken but the bootloader is ok, therefore you have a chance to restore it.

This procedure allows you to unbrick your cam but you need a backup file (which you did previously).

1. Copy the file mtd3.bin in your sd card

2. Rename the file user.bin

3. Reboot the cam and wait a couple of minutes
