MEGA with bootloader, but don't upload the sketch

Development Tools Uploading
1

So, I got a new Arduino Mega (chinese clone with CH340).
I plugged the USB cable, and drivers worked perfectly (has another MEGA clone with CH340 too that works without any problem).

To test, I tried to send the 'Blink' example, and got timeout from avrdude:

avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_getsync(): timeout communicating with programmer
An error occurred while uploading the sketch

So, I was thinking... maybe this board don't have bootloader!
Got my USBASP 2.0, and burn a new bootloader...
everything seens ok:

C:\Program Files (x86)\Arduino\hardware\tools\avr\bin>avrdude -C ..\etc\avrdude.conf -c usbasp -p m2560 -v -e -U efuse:w:0xFD:m -U hfuse:w:0xD8:m -U lfuse:w:0xFF:m

C:\Program Files (x86)\Arduino\hardware\tools\avr\bin>avrdude -C ..\etc\avrdude.conf -c usbasp -p m2560 -B 1 -v -e -U flash:w:"c:\Program Files (x86)\Arduino\hardware\arduino\avr\bootloaders\stk500v2\stk500boot_v2_mega2560.hex":i -U lock:w:0x0F:m

and everything seens to be ok (according with avrdude)

avrdude done. Thank you.

plugged the usb again, started the arduino ide, and tried a new attempt to upload the 'blink' example on this board... but still, the same error:

avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_getsync(): timeout communicating with programmer
An error occurred while uploading the sketch

any help on this?

How about the LEDs (Rx, Tx, L) during upload? Try loop-back test if the USB/serial transceiver works. Search for it here on arduino web or google.
