The main updated process is to place 4 plastic pads under the controller mainboard to make the board more fixed.
NOTICE:
Soldering is optional, if you don't need the touchpad button, the L3 & R4 buttons can be mapped, so please skip the soldering process.
The installation was demonstrated with the PS5 BDM 030 controller, the BDM040 is similar to it.
The tutorial includes the plastic version and the metal version of the RISE4 kit.
