Can't flash to 4.3.0

I'm sure I'm doing something wrong. I'm following the instructions to upgrade firmware to 4.3.0, but the printer behaves as through there is no *.bbf file on the flash drive. I've copied prusa3d_fw_4_3_0_MINI.bbf to my drive. It is 778800 bytes long, and the only file on the drive.

It is formatted FAT32 - is that OK? I'm currently running 4.2.1-final.

Any ideas?

I don't have a mini, but there have been a few reports of the Prusa USB Pen being sub standard, could you try a different USB pen?

Just went to the upgraded yesterday, using the Prusa USB drive.

My process:

* Copy file to USB drive. BTW, I have a lot of other files on there as well.

* Turn Mini on, without USB drive

* Insert USB drive

* Press the reset button.

If that doesn't work, try a different USB stick. Or redownload the image. Maybe something got screwed up. I don't see why FAT32 shouldn't work.

Insert the USB stick - reset the printer - then press the LCD control button 2x briefly. After that the flash menu should appear.

So when I posted this question I had already tried three different flash drives - one of them was the Prusa drive - all failed. It just worked with a fourth. Go figure.

I have two Minis and 2 different clones and it appears to work for them.
