Crossflashing 1633S ==> 1653S

Hi guys, merry christmas to all of you !

I am thinking cross flashing my 1633S to 1653S. But with the new firmware I noticed the 1653S switches from -R X12 to -R X16 ! Do you think it is safe for my 1633?
Has any body done it ?

Happy holidays!

This question has been asked before…

Short answer: yes, you can… also, it’s 8x->12x, NOT 12x->16x
