seeeduino v3.0 cant upload blink led, try a lot

Hi guys this is my first time with an arduino.

I have a seeeduino V3.0 Atmega 328 compatible.

I checked all the basic: cables, drivers, ports, loop back test, flash the bootloader and not success.

i get the error avrdude.exe: stk500_getsync(): not in sync: resp=0x00

When i try to upload both TX and RX LED blink


Loopback test doesn’t gave me any echo. each time i hit send RX and TX blink at the same time. but no response


With FT_Prog i got to view the EEPROM
Read EEPROM Device 0

chip type FT232R

vendor id 0x0403

pro id 0x6001

prod descp: FT232R USB UART

serial #: A9YLXZRJ

so i think this is working fine


when using the bitbang method to change FUSE values guiding me by this:

seeedstudio.com/blog/2009/11 … g-problem/

it not pass

avrdude.exe: BitBang OK
avrdude.exe: pin assign miso 3 sck 5 mosi 6 reset 7
avrdude.exe: drain OK

ft245r: bitclk 4800 -> ft baud 2400
avrdude.exe: ft245r_program_enable: failed
avrdude.exe: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.

avrdude.exe done. Thank you.

I think i have a bad seeed so there is any other test that i can do before ship it back to amazon?
