RN102 won't do the factory reset

Has anyone on this thread been able to boot from USB, as in the suggested article

I haven't

I have 2 flash drives (USB sticks). One of them has activity LED, the other doesn't. But both satisfy criteria mentioned in the article. I went through all steps with each of my flash drives.

1) First I try my USB stick without activity LED.

I insert it into the front USB port with ReadyNAS turned off. I plug in the power cable while holding "Backup" button down. All LEDs blink for 10-15 seconds while I am holding the button down, then after 20-30 seconds all of them stop blinking and stay steadily lit forever. ReadyNAS does not power down after 30 minutes. So I presume the boot update fails.

2) Then I try the stick with USB stick. Again, I diligently follow all steps in the article.

I plug the stick into the front USB port with ReadyNAS turned off. I plug in the power cable in while holding "Backup" button down.

Power and Backup LEDs of the NetGear start blinking, 'act' LED is steadily on while I keep holding 'Backup' button down. After 20-30 seconds the activity LED of the USB stick lights up and stays lit for approx. 5 seconds, then it goes out.

Power and Backup LEDs continue blinking, 'Act' LED is steadiy on. The ReadyNAS stays in this state forever, there is no automatic powerdown. Apparently boot from this USB drive fails too.

Could anyone share their experience? What am I doing wrong?

Thanks!
