You never acknowledged that you formatted the drive on the SX900. Don said that's a MUST. Just in case you missed it.

Have you tried the the usbs by saving something on them?
I downloaded a list from Yamaha site that listed the USB’s that had been tested for use ( or something along those lines also I think they can only be up to 32 gig, if I remember correctly. I had a couple of 16 gig sandisks the type I had weren’t mentioned on the list , but they did work.

When I did my update I must have been having a bad morning, haha, or nervous about doing update, I didn’t quite understand the

C. Extract the *.prg file and copy it to the root directory of your USB flash drive.

I did the extraction, then,
Wasn’t sure if it was supposed to be left in the extracted folder or just the file inside the folder.
I had both on there, went thru procedure and it worked as it should.
Still haven’t got a clue which was the correct one.

I've not checked the SX manual, but if there is two USB ports at the SX and a USB stick also is connected in the other than where update file is at same time, that may be the problem.

You can only have ONE USB drive in when you update.

Only had one USB stick in. Formatted 2 different sticks. Unzipped the file on computer and copied files to usb stick. SX appears to be looking for files as it continues to flash. It's just not recognizing them and moving on to the next step. I'll try a fresh usb stick tomorrow. Done this a million times...totally perplexed??????

If used same USB port when the update fails, maybe worth to try the other one as well just in case one port has priority 1.
Usually it doesent matter, but who knows. 🤔
A factory reset may help to fix softwarebug if it's not a hardware issue.

ha. Love these simple to use new keyboards!

Have you done a complete factory restore and then try to re-install it

What USB drives are you using as the keyboard may not like some of them. There's a list of compatible drives to use if unsure.

Also, have you run some other checks or tests, like can the keyboard read any other files OK such as midi files, styles, multipads, regs etc.... if the SX900 can't read anything at all then it's pointing towards hardware either with the drive or God forbid the keyboard itself... However, if it does load any other types of files, then I think you may have a corrupt install file? Try downloading and extracting it again, put the file in the root of the USB stick, eg, not in any folders etc..

Hope it works out.
All the best.

The SX allowed me to format both USB sticks...And I've tried both USB ports separately. Like I said...The USB stick will flash as if it's reading data...just won't take me to the next install page.

I'll try a system restore and a different usb stick tomorrow. I'll also re-download the firmware and unzip. If I'm not mistaken...after unzipping the file, there are 5 or 6 different files on the drive. Does that sound right?
Thanks,
