NO modifications after reboot

Hello to all. I'm facing something strange... I'm working remotelly with putty. 1) I modify the /ect/rc.local to have some program @ sturtup. sudo nano /etc/rc.local 2) I save and exit.

Hello! After using device with USB power supply, I decided to solder wires to use a Lab PS. Because I'm lazy, I didn't double checked the schematics... and I powered (5V) for 20-:-30sec thru P6, which is dedicated to reset. When I understood the error, I reverted to USB... Now, the Rasperry show sta...
