This Quick Solder Flex PCB makes installing the PicoBoot mod a breeze and without having to use any wires or bend the corner of the DVD Drive enclosure to fit wires as in a normal installation. Installation Video is at the bottom of this page (Flex PCB has 1 additional leg to solder to).
The Quick Solder Flex PCB is super thin and easily fits between the motherboard metal enclosures without any damage or obstructing the enclosure. It solders directly to the IPL chip (U10 on motherboard) and has 2 areas with 3M tape making it easy to mount to the motherboard and the Fan Shroud for easy access to the USB Port for future updates.
PicoBoot was made by Webhdx and his github to the code as well as instructions on how to program the Raspberry Pico are on his github page.
You will also need the SWISS software to boot the ISO or Homebrew and that is below. To make use of the software you will either need an GC2SD or an SP2 Micro SD Adapter.
