Owner stated that tilde is stuck and wanted a bolt modification. No good photos here. Just posting some for reference purposes only.

Spring on the tilde got loose.
Too much gunk here. Needed to brush each boot.
Tilde's spring and boot.

...and here's blooper. When I inspected the springs after assembling, i noticed there was no spring in the pad enter switch. I really got confused because there's no more spring left. None the less, i re-opened and installed the missing spring.

After the 2nd assembly and re-inspection, i found the missing spring... Decided to leave it where it is since it will do no damage nor issue.


I decided to give my RALT button to complete this unit.
