All good! but you are missing the last step as you will need to replace the Dpad contacts and place them on the new bumper.
I broke the Step 17 connector's support, with no preassure, just as a lever, any idea on replacing the DAF7ATH16F0 Rev F (last 0 may be a O) board? I will solder the broken connector but I don't think I will be able to, so small

This part is not available in Canada, I've seen your product advertised all over the tech industry, but this part is not available to ship to Canada, that's too bad, I would have purchased the repair kit along with this part, I guess I'm stuck with the rma process. I guess right to repair is still very broken.
there should be a picture of the SD card slot at the start of every Steam Deck teardown. i know the note is there but i generally use the pictures to guide me and forgetting to remove the SD card is a very critical step
