Watchdog Timer burned!

Hi Im using Arduino_18, just now i tried to use Watchdog timer_30MS and guess what, it makes 13 blinking all the time. Now, i cant upload anything to my arduino mega. Some one, plz save me.... :'(

Yes this is because the watchdog kicks in before there has been time to recognise the download.

The only way back is to re burn your bootloader (and fuses) with a programmer.

What and how programmer should i do?

Thx ;)

Sounds like my issue here...

There may be an alternate to reburning bootloader.
