avrdude: verification error, first mismatch at byte 0x0002
         0x6a != 0x61

Using another uno does not give error. uploads fine. this uno does not upload. gives error above.

Does a smaller sketch upload?  How old is it?  As Nick already asked, where'd you get it?

Could be the flash on the ATmega has failed.
