Hi, I know that xyz da vinci jr printers are probably scrapped already but maybe anybody could help me to recover my Da vinci jr 2.0 mix?

I erased flash sad

Have no dump, no idea how can i unbrick it.
Maybe anybody have atmel dump for that printer? or is there any way to port repetier fw for that printer?

Probably too late but do you still have the issue? If you do so, i can probably try to help you with that.

I had some spare time to poke at this a bit more.  I was able to modify the bossac utility to connect, read, and write to the flash.  I erased the flash, wrote the firmware bin, verified, and set the boot mode to flash.  However, I'm still not getting a bootable printer at this point.  Not sure what the deal is.

Hey! I know I'm a tad bit late here... But how did you modify BOSSA to write correctly? I am connected successfully to my davinci mini w+ board and can read from the board but cannot write to it, it just fails with a 'SAM-BA operation failed' error. Could you share your custom BOSSA version, if you still have it?

Re: Davinci Jr Repetier Port

Sorry to bother you guys  i know i'm over 8 years late but i've been reading your quite interesting work here, could i ask any of you for serial number/model etc of the U2 IC it got burned on my PCB and i cannot find the serial model anywhere. I got throu i think 5 pages of this discusion so far but if i don't find it here i think it's safe to ask ^^. Thank you in advance. I'm a bit baffled if i should repair it or repurpose it seeing how hard its to find good info on parts etc but we'll see.

Edit: Forgot to clarify i meant U2 on the main board
