Acurus ACT 4 firmware update problem/question to owners


Hi!

I have an Acurus ACT 4 (16 channel) with some software bugs. A few specific menu points hang the device screen so that it has to switched off with the back panel power button.

I'm trying to resolve it with the firmware update, but can't understand how the hell it works. I select the update menu on a device, then it asks to connect the flashcard and then nothing happens.

Can anybody please help me to understand how the firmware update works on the ACT and/or probably share your experience resolving software bugs?

I hope those issues will be solved .
Christmas is coming and with Covid confinement ; we need our gears   to work flawlessly.

The good point is that if you have to ship your ACT4 , for repair , they will  upgrade it to 20 channels at no cost.You five years  warranty is reset
As long as you are the original owner. The warranty is not transferable .

All the best

I do hope to solve them too. But after your comment sending the device to service and upgrade is tempting too :)))

I have tried to find text where it is written that the 20 channels upgrade is free.  Without success.
But , I am shure , I have once read it.
So , confirmation about that from Indy Audio Labs is required.
