Uncompressed file (after you download check this properties:
- size: 326.454.784 bytes
- size on disk: 326.455.296 bytes)
If not have that size, try to download the file on other PC, it might be a problem with your PC, could be infected with some viruses which it modifies the files (supposing), or deactivate the antivirus when copy the file to USB.
Before copying file to USB stick, format USB stick using keyboard's Format utility! (if it was already formatted in keyboard and you have important data into it, make sure you have a recent backup of that data on your computer, better on cloud servers).
Reformat the USB stick. Insert the USB stick in your PC and copy the "Genossetup.prg" file in the root of usb stick. What means that?! it means when you insert the USB stick in PC and open it you will see only one file named GENOSSETUP.PRG, not folder, or anything else. (You may see a "System Volume Information" folder, but it's ok, that means you have the visibility of protected system files set to true, it's not so important for this process).
Insert the USB in your keyboard and restart the update process: press Start/STOP button and in the same time, the power button... etc..
IMPORTANT!
According to update script, the minimum version to install this OS is 1.01. So it does not need to have 1.30 version installed to install 1.40 version.
If you cannot finish the update, seems you have other problems, possible internal hardware problems.
PS: Try to not power Genos from an UPS system when you update it. Some UPSes does not give the exactly 220-230V at 50Hz... Maybe that's affect some components, I don't know.
PS2: Did you tried to do a reset to the keyboard before update?! With keyboard shut down, press rightmost key and while hold it, press power on button. It will erase all the data you have on the keyboard, so be carreful to have backup of important data and settings!
