Bricked Arduino? (LB: Future programming and verification disabled)

Development Tools IDE 1.x

I accidentally programmed the lock bits in AVR Studio with LB: Future programming and verification disabled =(

Any way to clear it out? When I try to use avrdude to reset chip (avrdude -p m1280 -P usb -c avrispmkII -e) I get the following error:

avrdude: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100% 0.02s

avrdude: Device signature = 0x000307
avrdude: Expected signature for ATMEGA1280 is 1E 97 03
avrdude: safemode: Verify error - unable to read lfuse properly. Programmer may
not be reliable.
avrdude: safemode: To protect your AVR the programming will be aborted

avrdude done.  Thank you.

Thanks.

See section 27.6 of the data sheet - you need to be able to pulse 12V to it to clear the bits.

Wow.
Tough tradeoff - $6 for a bare board, build up & populate etc. Handy tool ot have for the future.

Or new blank part for $4.50 from Newark.

Yeah. High voltage programming is definitely the deep end of the pool.

This is a mega board with nonremovable chip... Guess this board goes to the parts bin.

Can you send it to me? I'd like to practice taking the parts off with my hot air station.
