To detach the battery, don’t forget to remove the solder from the two points where the battery connects. (For Cozmo Collectors edition w/ press-able backpack button)

The soldering steps are wrong. Don’t desolder the speaker, but do desolder the battery.

Step 9 should be operated while the arm is at his maximum height.

ticom3 - Dec 30, 2022

Yes, excellent tip!

Step 9 is the hardest from far ! And you’ll easily get hurt by your tools. Moreover, reassembling cozmo will certainly deteriorate it. You should operate the big part of the arm (the lower) while the arm is at his maximum height. To do so, disassemble the white part of the fork by prying it down. Then remove the 2 screws of the upper arms, and remove these arms. Eventually, the big arm is easy to remove (or to reassemble).
