Hi,

I keep receive the message as shown follow while upload the sketch to the Arduino Mega 2560 r3. Indeed, the message area is still showing the stage "uploading". At the same time I am receive the random code from serial port of the Arduino device and with TX led is always turn on.

Sketch uses 1,518 bytes (0%) of program storage space. Maximum is 253,952 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 8,183 bytes for local variables. Maximum is 8,192 bytes.
avrdude: verification error, first mismatch at byte 0x0000
0x14 != 0x06
avrdude: verification error; content mismatch.

I have try to reset the device by upload again the boot-loader. Yet, receive the error message as shown follow as well. What actually going wrong with my device?

Trying to modify the bootloader when you have doubts about the ability to communicate does not seem very sensible.

Now you can't tell if the problem is because you screwed up the bootloader - or something else entirely - or both.

Can you upload the simple Blink example?

Try deleting and re-installing the Arduino IDE.
