It's crazy but the latest FW is not available the in the product's page, there are newer version scattered through the forum's messages.

Here is the latest that I have from 14/08/19: https://fil.email/zafhGGnH

It's exactly the same firmware. Just the file name is different but you can use it with no problems.

By the way, it is possible to restore the scope to the factory defaults, including the older firmware if needed.

Yes I know, you can't directly install an older FW on top of a new one. What I meant is that you have to first restore the oscilloscope to its factory default, that will probably bring back an older version of the FW so then you can install the other version that you want (if it's newer).

Try this, turn off the oscilloscope. Press the button to turn it on, wait 1 or 2 seconds and turn it off again. Now turn it on one more time and wait for the boot, you should see on the display a menu, select the F2 option to restore the system and confirm. Wait the process to be completed it takes a while. DO NOT interrupt the restoration in the middle of the process.

But why do want to install an older FW? Have you tried the version I've posted above? It's holiday in China this hole week, so don't expect any reply from them soon, but if you can wait a bit they'll fix any issue reported to them.
