e260 keep restarting...

My sandisk e260 keeps restarting over and over.

Some mounth ago I had a problem that told me to turn the Sandisk on Recovery mode…I did well with this problem and fixed it, I instaled a new Firmware.

Now, Like I said, it keeps restarting over and over. I tried to do the same things as I did the first time but it never works!

Please someone help me T_T and sry for my english!
