ElecGear Hall Effect Joystick Replacement for Steam Deck, Electromagnetic Sensor No-Drifting Left and Right Thumbstick Unit Module PCB Assembly for MEDA and MHDA Controllers, Repair Tool Kit included

The instructions are limited to one small square page. They have little detail nor any images. As such I will detail my experience installing these:1. Watch a video of someone opening the steamdeck. It uses 8 screws and plastic edge clips. The screws are easy, the edge clips are a little iffy to pry apart and I needed to use more force than I felt comfortable with, but it seems the shell plastic is strong and it survived well.2. The cables for the capacitative thumbsticks are glued. This hot glue was actually more difficult to remove than doing the soldering. It was also more difficult to reapply as the blobs supplied were really too big.3. I cannot recommend the use of flux to assist with soldering enough. As you can see in my pictures, one is perfectly soldered and the other messy. This is down to not using enough flux on one.4. When recalibrating the new sticks, you must enter desktop mode and use a command in the terminal (konsole). This requires the onscreen keyboard or a plugged in keyboard. To enable the onscreen I found I needed to be connected to a network, allow a steam update to complete then use the steam button and the X key together to bring up the keyboard. Without steam running and updated, the onscreen keyboard would not open.5. To fully test the new thumbsticks I suggest aperture desk job as this is one of the few games that has an indication for the capacitative touch on the thumbsticks being used, there does not appear to be a system check for these functioning. Most games do not use these so you can, if you choose, not solder the wire from the thumb stick. This is up to you and it would lose a function of the steamdeck.I also wanted to note the plastic tweezers supplied with these are fantastic, but the supplied screwdriver feels slightly oversized for steamdeck screws.
