can you install Rebug 4.70.1 REX over any CEX CFW?
Are you going up so from lower than 4.70 or not? If you are then yea there's no worry, just install it. If you're not then you'll just have to try and see if it works. Some people say if you have QA flagged you can just install lower over higher firmware, although I haven't personally tested this.
