Unfortunately, the screws won't help you disassemble the chassis.
The chassis consists of two parts; top and bottom.
Both of them are tightly bonded together internally, holding the PCB.
The screws make them fixed harder, especially the USB-C connector.
But, releasing the screw lock won't make the disassembling possible.
As always, we strongly recommend not replacing the battery for safety.
Anyway, after releasing 5k in the market, we'll keep updating the F/W.
And we're planning to release the accessory package for 5K.
