hi , i don t think. Here is how is the switch at startup as an attachment.
Good day

So you need disaster recovery via usb.
prepare a (switch recognized) USB stick (test with "usb enable" "cd /uflash" "dir" on other switch)
create directory 6350 on stick
create directory certified inside /6350 on stick
copy AOS Image files to /6350/certified
plug in usb stick
reboot switch (watch console)

regards

I am facing the exact same problem right now.

ERROR: /uflash/<target>/certified not found

I've done this procedure on the 6450 many many times, but on the 6350 it's not working as it should. Interestingly, if a folder /6250/certified/ is created, the switch attempts to access it. However, it will not load the 6350 image-files if they're put into it. Renaming doesn't seem to work either.

I've opened a support case for assistance.

I've figured it out. At this time I believe the stock miniboot on the switch is either bugged or the incorrect image. I've changed my support case to have this guess confirmed.

The way to recover a formatted flash from the USB Stick is quite simple, even with the wrong stock miniboot. This method requires the USB Stick to be set up correctly and plugged in.

[Miniboot]-> cp "/uflash/6350/certified/*.img","/flash/certified/"
[Miniboot]-> reboot

The current software OS6350_6.7.2.122.R08_GA_Release has the correct miniboot.bs included. After booting the switch:

-> usb enable
-> cp /uflash/6350/certified/kf3miniboot.bs /flash/
-> update miniboot all

Once the new miniboot is installed, the USB disaster recovery works as it should.
