Yes. But you have to make sure you have compatible Atmel dump for your printer.



@ guus46a

there is no Nano Atmel dump available at the moment.

So now i have a pricey paperweight


I wish somebody would send a global PSA to tell people to stay away from XYZ machines. This is the issue with them. Due to the fact they are closed firmware if it crashes there is no source for the recovery firmware. Then lets not even get into their filament systems. I would you advise you to just sell it for what ever you can in parts and and ad some money to buy and open source system for $300 to $500 USD.

The other issue is they market their machines as if they where an HP paper printer and all you do is p[lug it and go. Yet they offer no support, no parts, and no service. If you want it serviced you have to pack it up and ship it to Taiwan at your cost.

Re: XYZ Firmware Flash Tool [Downgrade daVinci to any older Firmware]

I can dump your Nano firmware from the Atmel chip. After that we can spoof it to very low version (e.g 1.0.0) and after that update to any other firmware version you like (e.g.1.1.0).

For that you have to send the PCB to me (Germany).

Re: XYZ Firmware Flash Tool [Downgrade daVinci to any older Firmware]

EDIT: False alarm I think. It would not recognize the last tag I had been using, nor a couple others that may or may not have been in the printer sometime before. When I put these back in my programmer and read them, they had an odd value (AE, A7, and 80) written to the first byte of the spool serial number.

It is however currently working with a newly created tag.

END EDIT

So, I've done the following steps...

1. Removed all XYZ software from my computer and deleted folders and registry.
2. Downloaded BOSSA and the 2.2.4 Atmel dump for the Jr.
3. Erased the Atmel chip and flashed the firmware. The printer confirms version 2.2.4.
4. Installed an older version 2.1.26.1 of XYZware.

Printer boots and everything looks good, however attempting to print errors with unrecognized spool.  I tried a few different paper tags that I had used successfully before.

Is it possible they updated something in the firmware of the NFC?

Hi Modfreakz, it looks like the filament chips that where in the nano are not been readed anymore, but the filaments that haven't seen by the printer are working correct. So there must be something happened with the original chips and the nfc stickers

Did you let any of the chips or tags reach zero or did the printer tell you there was not enough filament to print a job with on any of the tags or chips? If the printer sees a tag or chip as not having enough left it will flag that chip or tag as empty and that chip or tag can never be used again.

Actually after you run 100 serial numbers through the machine you could go back and re-use chips that where outside of the current 100 count.

Re: XYZ Firmware Flash Tool [Downgrade daVinci to any older Firmware]

This doesn't appear to work for my Davinci Jr 1.0, with current firmware 2.4.7. Says successful, but fails on the printer.

82

Re: XYZ Firmware Flash Tool [Downgrade daVinci to any older Firmware]

Still No solution/fix to downgrade from 2.4.7?

Re: XYZ Firmware Flash Tool [Downgrade daVinci to any older Firmware]

Hi,

I'm new comers into xyz printer modification, I'd like ask your help about how to do operate laser engraver (RS1J0XY105E) with XYZ da vinci Jr. 1.0 (version 2.2.7)?
The printer head connection are compatible (electrical and and mechanical also), but the XYZengraver software cannot to detecting it, when installed laser head.
Of course the XYZPrinter can recognize and working it with printer head correctly.

THX,

Re: XYZ Firmware Flash Tool [Downgrade daVinci to any older Firmware]

Still doesn't downgrade from 1.1.3 any ideas?

Re: XYZ Firmware Flash Tool [Downgrade daVinci to any older Firmware]

Hi,

I have a Da Vinci Jr Pro 1.0 and up until about a month ago, I hadn't printed anything on my printer for about a year.  After firing it back up, I upgraded the firmware to 1.1.7, and now when trying to unload filament it tries to unload the filament first before heating up.  Either that or when it's hot, it cools down first and then tries to unload the filament.  It never did this before this 1.1.7 update.  I tried to downgrade to 1.1.5 and 1.1.6 to see if this resolves the problem, but when I run the Flasher, I get a window that pops up and says downgrade was successful, but on the printer it says it failed.  Is my printer not compatible?  I'm about ready to take a sledgehammer to it Office Space style.  Thanks.

86

Re: XYZ Firmware Flash Tool [Downgrade daVinci to any older Firmware]

I'm having similar issues with my minimaker. I also cant downgrade to erlier version of firmware. It's the same. Flasher says downgrade successfull but the firmware stays the same. Using Da Vinci Minimaker with 1.2.2 firmware wanted to downgrade to 1.1.0

Re: XYZ Firmware Flash Tool [Downgrade daVinci to any older Firmware]

I have posted the reason in earlier post (36)


Ones again!


XYZ fixed the possibility to flash the same firmware version as already installed on the printer.

I have exploit this bug/vulnerability in my program to downgrade the firmware.


In other words.... XYZ makes the firmware comparison like this now:

Befor:

If (Installed_version <= Update_version)

After:

If (Installed_version <  Update_version)


At the moment you have only one possibility to downgrade, look here!
You have only to make sure first, that you have any Atmel dump for your type of the printer.

Re: XYZ Firmware Flash Tool [Downgrade daVinci to any older Firmware]

Hi Modfreakz,

Firstly, thanks so much for what you are doing for the community.

I made the mistake of updating to the newest firmware. Tried to revert to old but it did not work as you mentioned in your previous post. Then I used the amtel dump option and flashed it back to an earlier version, still without success.

Can you please assist. I don't know what to try next.

89

Re: XYZ Firmware Flash Tool [Downgrade daVinci to any older Firmware]

what type of printer do you have?

Re: XYZ Firmware Flash Tool [Downgrade daVinci to any older Firmware]

Hi,

I have the Mini w. The Firmware version that broke it was 1.3.5 and I flashed it to 1.1.9.

When I try to use the firmware it beeps a lot and fails. I attached screenshots from the converter tool that I used to save the Atmel dump.

Re: XYZ Firmware Flash Tool [Downgrade daVinci to any older Firmware]

Hi,

I have found a workaround/solution. Just sharing in case others are struggling too.

I downgraded my firmware by using this method : http://www.soliforum.com/topic/17845/do … rmininano/

It still would not work. Then I used an offline laptop and installed an older version of XYZWare. Do not update to newest version if it asks.

I then had to create a new tag using the Reeltag tool on my phone and it worked. None of my old ones work.

Thanks a lot Modfreakz for everything you are doing for this community, your tools are a lifesaver!

Re: XYZ Firmware Flash Tool [Downgrade daVinci to any older Firmware]

I am having a heck of a time getting my Mini W+ to downgrade the firmware.  I downgraded the software thinking that might help for some reason, but I'm just not having any luck. It keeps on seeing the firmware as 1.1.9. Any suggestions?

So are you only able to use your printer with this offline computer?

Re: XYZ Firmware Flash Tool [Downgrade daVinci to any older Firmware]

Hi, I used the v1.50 tool, and it works for my mini maker firmware up from 1.0.4 to 1.2.0 but when I decrease from 1.2.0 to 1.0.4 again, I find  My printer can't  read the RF filament information, it's appear "--", and when I print same thing , the led will go to red, even if I used the official filament I's the same.

So I don't know what happen for that!

Thank you very much

That is because the firmware update was not finished properly (update for some internal modules like NFC, wifi,.....)

You should have waited longer.
After the "update successful" message, it can happen that you will hear a noise for a while.
That means that internal update or similar is still in progress. The whole update can take up to 2-5 min.

Do not turn of or press anything till the printer recognized correctly in device manager.

In your case, flash your favorite firmware again.

Re: XYZ Firmware Flash Tool [Downgrade daVinci to any older Firmware]

a question ... can i load the davinci jr 1.0 pro firmware on a davinci jr 1.0 w the pcb are similar.

Re: XYZ Firmware Flash Tool [Downgrade daVinci to any older Firmware]

Hello,

yes you can!

1. you have to use the Bossa way
   http://www.soliforum.com/topic/17845/do … rmininano/

2. you need Atmel dump for davinci jr 1.0 w

Re: XYZ Firmware Flash Tool [Downgrade daVinci to any older Firmware]

eu entendi os processos e como fazer a atualização da davinci jr 1.0w que já tem o arquivo dump dentro da pasta.

agora pergunto a você como eu crio um arquivo dump para converter a davinci jr 1.0w para o firmware da davinci jr 1.0 pro w.
sei que e possível  pois ambas as placas são iguais.
só não sei criar o arquivo dump para converter a impressora.
