Topic: Da Vinci 1.0 Pro bricked after firmware update.

I can't seem to figure out how to restore the old firmware. The printer isn't being detected in device manager and there are black bars on the screen. The pro doesn't have the jumper pins labeled anywhere on the board.

Re: Da Vinci 1.0 Pro bricked after firmware update.

I did read about it on a post you had made in the past: http://www.soliforum.com/topic/17845/do … mininano/. I can get my hands on one. Afterwards, what should I do with the device? To my knowledge, there isn't an atmel dump publicly available for the Da Vinci Pro 1.0.

Re: Da Vinci 1.0 Pro bricked after firmware update.

I know there is no Atmel dump. But I thought if you have enough skills and jtag hardware then you could make a dump of your bricked mainboard.
That would be enough for me to extract the AES de/encryption key.

After that you will get working Atmel dump.

Anyway, did you thought about alternative firmware, called Repetier?

Re: Da Vinci 1.0 Pro bricked after firmware update.

I'm pretty sure the guy who I bought the printer from recently tried to reset it and flash it. I don't think the dump will yield anything promising. I am open to using repetier but don't know how to install it on the pro 1.0.

I think I can help you with resetting and flash tools. But you still need the Atmel dump or Repetier firmware file.

Please make clear photo of the PCB, I have marked red the important area. See photo.

Re: Da Vinci 1.0 Pro bricked after firmware update.

This is the JTAG port to get the Atmel dump.

SW1 is reset signal for Atmel.
SW2 should be the flash erase.

You have to erase flash before use any programming tools.

Re: Da Vinci 1.0 Pro bricked after firmware update.

I got my hands on a J-Link. I got every wire connected up. Now what software should I use to proceed further and what steps should I take to get the Atmel dump in software?

Re: Da Vinci 1.0 Pro bricked after firmware update.

Very nice, thank you for the dumps. I was able to extract the AES key.

Give me some time to update my program. You wil be able to downgrade/recover you printer.
