  1. Install Series 2 Display on a Series 3 with Apple Pay, Meet the patient: 手順 1、 1の画像 1
    • Here we have a Series 3 Apple Watch with a broken Display.

    • Sad.

  2. Install Series 2 Display on a Series 3 with Apple Pay, Open 'er up: 手順 2、 1の画像 1
    • Remove the broken Display. The worse they're busted up, the easier they come off!

    • Remove any adhesive residue and tape from the Force Touch Sensor, and inspect it for damage. Replace if necessary.

  3. Install Series 2 Display on a Series 3 with Apple Pay, Prepare the donor: 手順 3、 1の画像 1
    • The right-hand module contains the NFC and Light Sensor. It's attached by some adhesive dots, two solder bumps (for the NFC antenna connection), and some copper tape.

    • Cut the copper tape from the NFC module.

    • Using an Xacto #17 blade, chisel the NFC module from the damaged Display.

    • Keep the blade as parallel as possible to the Display.

    • Now the NFC module is free. There's some tape on the back of the module; you can peel it off with tweezers.

    • You can see there are two solder bumps under here. These are the connections to the NFC antenna.

    • If you use alcohol or some other solvent to help clean up, use it very sparingly. We don't want to mess up the Light Sensor.

  6. Install Series 2 Display on a Series 3 with Apple Pay, Meet the New Guy: 手順 6、 2の画像 1 Install Series 2 Display on a Series 3 with Apple Pay, Meet the New Guy: 手順 6、 2の画像 2
    • Here is a "new" (probably harvested) Series 2 Display I bought online. I marked it with a "2" just because.

    • Remove the NFC module from this display. You can discard it or sprinkle it on your breakfast cereal.

    • I got a little over-aggressive taking this off so you can see I removed some of the black tape covering the NFC antenna. No harm done, though, and it let me show a corner of the NFC antenna.

  7. Install Series 2 Display on a Series 3 with Apple Pay, A sticky situation: 手順 7、 1の画像 1
    • Now we apply a bit of "Z Tape" to the back of the module. Z Tape is nifty stuff that conducts electricity through its thickness but not sideways.

    • In this photo the release layer is still on the Z tape. We'll take it off before sticking the module onto the Series 2 Display.

  8. Install Series 2 Display on a Series 3 with Apple Pay, Frankenstein's Monster: 手順 8、 1の画像 1
    • Yup, that's our Series 2 Display with the NFC module from the broken S3 Display attached. Alignment here is fairly important so don't just slap it on all willy-nilly.

  9. Install Series 2 Display on a Series 3 with Apple Pay, Reprogramming: 手順 9、 1の画像 1
    • Sometimes it just works, and sometimes you need to reflash the OS to make everyone play nice together. Good luck finding the magic IPSW files.

  10. Install Series 2 Display on a Series 3 with Apple Pay, It works!: 手順 10、 1の画像 1
    • After all this, Apple Pay can be configured on the Watch and you can see that it talks to the NXP TagInfo app.

    • I had to use an Android phone to test the NFC because Apple doesn't let apps get deep enough into iPhone's NFC to read this stuff.

This is one of those guides that goes above and beyond. Now can you tell us how to flash the software?

viarengo1 - The tricky part of reflashing is actually just getting the IPSW files to flash — OTA update files don’t work and Apple doesn’t release the complete files. If you can manage to get the file, though, you connect the Watch to a programming adapter (either iBus or the Apple adapter), load iTunes, and the Watch shows up. Then you shift-click on Restore, point to your hard-won IPSW, and off you go. You can sometimes find Apple programming adapters on eBay and MFCBox sells the iBus, which is a clone of the Apple adapter. But the IPSW files are a major PITA. Right now I don’t think any of them are in the wild except WatchOS 4.3.1 for Series 3 only.

There are plenty of ipsws for Apple Watch on ipsw.me. Are they usable?

IO -

IO - No, the ipsws on ipsw.me and similar sites won’t work. They are over-the-air update files (“OTA”) and do not contain a complete set of code including boot loader and all modules.
