RE450 V3 power led flashlight after package updates

Hi

I did package updates to my RE450 and now it powers on with no wifi and only the power led is flashing on/of.
ethernet connection won't work either.
please tell me what is going on.
Thank you.

Upgrading packages (via the CLI opkg upgrade command or the LuCI Upgrade... button) can result in major problems. It is generally highly discouraged, unless you know what you are doing or if there is specific instruction to do so.

If you're already having issues, or wish to 'undo' the upgraded packages: create a backup (optional; can be restored after the reset is complete) and then perform a reset to defaults (firstboot).
