About firmware update

I’ve never changed 24 word (recovery seed) in my trezor.
2days ago, I’ve updated firmware of my trezor.
In this case, is it right still valid my first 24 word (recovery seed)?

Hii @yssy

Your seed/recovery words will always be valid even if you format and wipe your device.

These seed/recovery words do not change.

Very good explanation
