I made the mistake of buying one last year, the oscilloscope function was measuring 0.5V offset at idle and different voltages in normal measurements, I sent Fnirsi company a Whatsapp email message on every channel and waited for them to solve it with the firmware, they further corrupted the function of correcting a simple voltage offset with another clean voltage. It would be great if they added it or developed it themselves. After pages and pages of messages, I was left unresolved. The answer was that you bought this product from another Aliexpress seller, not from us. But I said the product is your product, but it would be more useful if I talked to the wall.
I mean, it's a product with potential, but since they don't have any engineering development skills, I don't understand why they can't fix the problems of the actual product while spending so much budget on marketing.
FNIRSI policy will be like this: New cool looking TC-4 with minor updates after release, no care for older devices
If it doesn't work from the start, you are on you own.
Cool opinion. Of course, it's still supported for now, and has a firmware download available on their website:

You must change also U10 ...

Thanks! That's good to know. I think they'll fix the fixable bugs eventually. I turned off the logo in there, now it starts up faster lol.
Has anyone found a newer firmware other than v0.30 ?

That's still the latest version on their website. I don't know where else you would find firmware.
Ask Finirsi for assistance on their WhatsApp Grup. They are quite helpful.
