Access to older versions of firmware - specifically for Doser 2.0

[porter_painter]

Hi folks,

I’ve recently updated the firmware on a GHL doser 2.0 (so white doser heads not the blue ones).

Unfortunately this seems to have bricked the doser and it’s stopped functioning. It shows in the GHL control centre, but I can not get the doser heads to work either from the manual buttons on the doser or via the control centre.

I only have firmware versions 1.42 to 1.45 available in the software folders, as I’ve recently changed my PC so don’t have old versions of the control centre which might have the older firmware.

Does anyone have a link to an older version of the Control Centre Software, or can share with me the doser firmware version 1.34 or 1.35 which I know was working before the update?

Thanks in advance
Andy

I´ll try to contact you by PM but you have block that possibility. I have V134 and forward for both SA and slave. Send me a PM with your e-mail and I will send them to you- However - I have update a similar doser with 1.43 without any issues

Sincerely Lasse

Thanks Gaël, but I had already done this procedure and it is not the problem in this circumstance.

Interesting point I found when doing the emergency flash for the doser, the process would not work on my laptop for the first 10 tries. I the decided to change the USB port I had plugged into my laptop and then it worked first time. It seems the emergency flash did not work with USB 3.0 port, but does with USB 2.0 port. I kept getting an unrecognised device error as the driver seems not to be compatible.
Once the flash was done, it worked ok with 3.0 USB for normal connection to GCC.
