i have the dreaded avrdude: stk500_getsync(): not in sync: resp=0x30

i dunno why is just popped up out of nowhere .tried all the usual ,com port looks ok . cables ok tried another Uno in its place and no deal....done a search on all possible solutions and tried em. tried with shield and without just a simple blink test and no dice ....

reloaded the driver and its back on the same port 5 , what should the baud rate be ?
still not working

Did you try the loopback test, see if the USB interface still works?

loopback test didnt work so reloaded a fresh driver still no good. so changed the atmel chip for a known good one and works ok now. i have been using a LOL shield so that may have caused trouble .LOL shield seems unstable ,seems like the pins from the LOL shield into the UNO are flaky
