iPad Pro 12.9" 5th Gen Logic Board Replacement

你所需要的

  1. iPad Pro 12.9" 5th Gen Logic Board Replacement, Prepare your iPad for disassembly: 步骤 1 中的图像 1,1
    • Allow your iPad's battery to drain below 25% before starting this repair. A charged battery may catch fire if damaged during the repair.

    • If your battery is swollen, take appropriate precautions.

    • Unplug any cables and fully shut down your iPad.

  2. iPad Pro 12.9" 5th Gen Logic Board Replacement, Heat the right edge: 步骤 2 中的图像 1,1
    • Apply a heated iOpener to the right edge of the screen for two minutes.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the iPad—the screen and internal battery are susceptible to heat damage.

  3. iPad Pro 12.9" 5th Gen Logic Board Replacement, Anti-Clamp instructions: 步骤 3 中的图像 1,3 iPad Pro 12.9" 5th Gen Logic Board Replacement, Anti-Clamp instructions: 步骤 3 中的图像 2,3 iPad Pro 12.9" 5th Gen Logic Board Replacement, Anti-Clamp instructions: 步骤 3 中的图像 3,3
    在这个步骤中使用的工具:

    • The next three steps demonstrate the Anti-Clamp, a tool we designed to make the opening procedure easier. If you aren't using the Anti-Clamp, skip down three steps for an alternate method.

    • For complete instructions on how to use the Anti-Clamp, check out this guide.

    • Pull the blue handle backwards to unlock the Anti-Clamp's arms.

    • Place an object under your iPad so it rests level between the suction cups.

    • Position the suction cups near the middle of the right edge—one on the top, and one on the bottom.

    • Hold the bottom of the Anti-Clamp steady and firmly press down on the top cup to apply suction.

    • If you find that the surface of your iPad is too slippery for the Anti-Clamp to hold onto, use tape to create a grippier surface.

    • Pull the blue handle forward to lock the arms.

    • Turn the handle clockwise 360 degrees or until the cups start to stretch.

    • Make sure the suction cups remain aligned with each other. If they begin to slip out of alignment, loosen the suction cups slightly and realign the arms.

    • Wait one minute to give the adhesive a chance to release and present an opening gap.

    • If your screen isn't getting hot enough, you can use a hair dryer to heat along the right edge of the iPad.

    • For complete instructions on how to use a hair dryer, check out this guide.

    • Insert an opening pick under the screen when the Anti-Clamp creates a large enough gap.

    • If the Anti-Clamp doesn't create a sufficient gap, apply more heat to the area and rotate the handle clockwise half a turn.

    • Don't crank more than a half a turn at a time, and wait one minute between turns. Let the Anti-Clamp and time do the work for you.

    • Skip the next step.

  6. iPad Pro 12.9" 5th Gen Logic Board Replacement, Insert an opening pick: 步骤 6 中的图像 1,3 iPad Pro 12.9" 5th Gen Logic Board Replacement, Insert an opening pick: 步骤 6 中的图像 2,3 iPad Pro 12.9" 5th Gen Logic Board Replacement, Insert an opening pick: 步骤 6 中的图像 3,3
    • If your screen is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken display.

    • Apply a suction handle to the screen as close to the center of the right edge as possible.

    • Pull up on the suction handle with a strong, steady force to create a small gap between the frame and screen.

    • The large screen is very fragile. Only create a gap big enough to insert an opening pick.

    • If you're having trouble making a gap, reapply a heated iOpener to the right edge for two minutes.

    • Insert an opening pick into the gap.

    • Don't insert the pick more than 5 mm to avoid damaging the screen.

Step 44 says to use a Phillips screwdriver to remove the two 2.2 mm-long screws securing the front camera. I'm working on a 6th gen and those screws are T3. In fact the pictures on step 44 look like Torx as well.
