But, the image and boot files would not load (Loading: T T T T ...) when I try update_primary and update_uboot. I'm able to ping to TFTP, and it works fine when I execute TFTP get command locally. I opened Windows firewall for UDP 69 and all ports, but still not working. Please help.
Thank you for the details provided, Please try a factory reset if the issue persisted, perform the software recovery, but disable the firewall first, if still not working please provide the logs of the error while you try the software recovery. (all logs, copy and paste them here)
Factory reset steps:
Remove power from the switch.
Press and hold theResetbutton while applying power to the switch.
After all the system LEDs flash amber, release theResetbutton.
When all the system LEDs blink green, all the configuration data are erased and the switch is returned to its factory configuration. When all the system LEDs are solid green, the erase process is complete and the system reloads. Once reloaded and the SYST LED is steady green, the factory reset is complete.
