 <note warning>Do not connect a normal P19 board via USB to the programming rig, you will break it.</note>
-For both methods, wait 5 minutes and then the board will be programmed automatically.
+For both methods, wait 5-10 minutes and then the board will be programmed automatically.
+===== Unit Assembly Instructions =====
+. Extend the P19 TFT backlight cable by 20cm. Heat-shrink the connections.
+. Install the rubber blanking cap (PN x) into the case.
+. Install the plastic vent (PN x) into the case.
+. Apply foam tape to the inside of the case rim as pictured.
+. Remove the screw-on nuts from the black plastic connectors. Do not remove the rubber seal.
+. Apply thermal paste (PN x) to the CM4 CPU die
+. Insert the PCB into the case. Affix using 1 washer (PN x) and screw (PN x) per corner as pictured.
+. Replace the screw-on nuts on the connectors on the rear of the case and tighten using supplied sockets. Take care to ensure the final orientation is as pictured.
+. Attach the backlight cable.
+. Attach the LVDS cable.
+. Lower LCD into case, insert 4x screws (PN x) into the mounting holes as shown. Be careful to keep LCD centered in the case.
+The unit is now ready for testing.
+===== Unit Testing Instructions =====
+===== Final Unit Assembly Instructions =====
+<note important>Testing must have been completed before proceeding with this stage. Check for a serial number label.</note>
+. Clean the screen with a soft cloth and glass cleaner
+. Apply a bead evenly all the way around the screen as shown
+. Return to the screen after 10 minutes and fill any areas that have sunk
+. Leave to cure for 12 hours
+. Clean any excesses from the metal and glass
+. Apply protective film to the screen
+===== Packing Instructions =====
+===== Raspberry Pi CM4 Resetting Instructions =====
+On Linux computer clone the following repository:
+  git clone --depth=1 https://github.com/raspberrypi/usbboot
+  cd usbboot
+  make
+  cd recovery
+  ./update-pieeprom.sh
+Mount the Raspberry Pi CM4 on the test IO board. Connect the IO board to the host Linux computer with USB to USB cable.
+Now use rpiboot on Linux computer to start the CM4 in Mass Storage Mode.
+  cd usbboot
+  sudo ./rpiboot
+Power up the IO board and expecting the following result:
+  RPIBOOT: build-date Feb 22 2024 version 20221215~105525 58548dc3
+  Waiting for BCM2835/6/7/2711/2712...

+After a few moments, one or more drives will appear on the host Linux computer. You can display these devices using the following:
+  lsblk
+Which will produce output similar to the following:
+  NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
+  sda           8:16   0 223.6G  0 disk
+  ├─sda1        8:17   0   529M  0 part /media/user/boot
+  ├─sda2        8:18   0    99M  0 part /media/user/rootfs_A
+  ├─sda3        8:19   0    16M  0 part /media/user/rootfs_B
+  └─sda4        8:20   0   223G  0 part /media/user/homefs
+You now need to clear the device that is mounted at /media/user/boot, which is sda1, as follows:
+  sudo rm -R /media/user/boot
+  sync
+Power off the device then one final action is needed to reset that to factory settings:
+  cd usbboot
+  sudo ./rpiboot -d ./recovery
+Reboot the IO board and the device’s bootloader will be replaced with the default:
+  RPIBOOT: build-date Feb 22 2024 version 20221215~105525 58548dc3
