(adsbygoogle = window.adsbygoogle || []).push({}); I'm on ReBug 4.75.3 D-Rex... Can I update to the same firmware or would I have to downgrade and then re-install it?

You can just update, you should be fine. If you are going to a lower firmware, you will need to downgrade. Going to a higher firmware will not require downgrading. Just a little information for the future :p

u can install the same or higher firmware over top of the existing one, this can be also used to fix a soft brick

Actually fixed the fan problem I was having

Good to hear. If you have any other questions feel free to make another thread.
