OK, I give up for now. Tried various buttons, using a FAT32-formatted USB stick at the front, without success on my ET9000.

 

Maybe one more try, just to be sure: delete all the files from the stick xmt the one you need for the box. Should make no difference, but who knows?

I did not have any other files on the stick. The question was just to know for image flashing in the future.

Also, I guess flashing should work from both USB ports, the one at the back and at the front?

I will give it one more try soon with a different stick but I don't have much hope.

If you extracted my zip-file to the stick you did have multiple files; best to delete the not needed ones in case of trouble.

AFAIK both front & rear ports should work, but trial & error might be needed.

Not all boxes support flashing from ports at the back, they're of a different type on a different controller.

 

Most do however have detection issues if there is another USB device connected, so make sure they're unplugged. I use a 30cm USB extension lead for that purpose, so I don't have to remove the box from its built-in spot to get the stick out of the back.

 

Also, the only two requirements for the stick are:

- formatted in FAT

- fast enough to be detected

 

The second point is why some USB sticks fail. The bootloader has a short timeout in order to minimise the boot delay, Size of the stick plays a role, but not a definitive one, I have 8GB sticks that work, and 128MB sticks that don't.

 

And it is fine to have other data on the stick, I usually have images for all boxes on my test bench on the same stick, together with a "tuned" backup I restore after flashing a test box.
