iPad mini 4 LTE Logic Board Replacement

Giriş

Follow the steps in this guide to remove or replace a faulty or water-damaged logic board in an iPad mini 4 LTE.

Note that if you replace your logic board without a paired home button, you will lose Touch ID functionality.

Parts of this guide were shot with a Wi-Fi model and as such the internals may look slightly different from the LTE model. The procedure is the same for both models except where noted.

    • If your display glass is cracked, keep further breakage contained and prevent bodily harm during your repair by taping the glass.

    • Lay overlapping strips of clear packing tape over the iPad's display until the whole face is covered. For particularly bad breaks, you may need to lay down two layers.

    • This will keep glass shards contained and provide structural integrity when prying and lifting the display.

    • Do your best to follow the rest of the guide as described. However, once the glass is broken, it will likely continue to crack as you work, and you may need to use a metal prying tool to scoop the glass out.

    • Protect your eyes! This procedure will cause small pieces of glass to fly directly toward your face. Do not attempt without safety glasses.

    • Apply a suction cup halfway up the heated side.

    • Be sure the cup is completely flat on the screen to get a tight seal.

    • While holding the iPad down with one hand, pull up on the suction cup with strong, steady force to create a gap.

    • Depending on the age of your device, this may be difficult. If you have trouble, apply more heat and try again.

    • Be careful to only lift the glass enough to insert an opening pick—any more and you risk cracking the glass.

    • While holding the glass up with the suction cup, insert the point of an opening pick into the gap between the glass and body of the iPad.

    • Don't insert the opening pick any deeper than 2 mm into the side of the display. Inserting the pick deeper than 2 mm could damage the backlight assembly, LCD display, or touchscreen.

This guide needs amending urgently before more people destroy their LCD displays by cutting through the tape holding the backlight to the LCD glass, or pushing a pick or other tool between the LCD glass and touchscreen glass.

The guide states:

Don't insert the opening pick any deeper than the black bezel on the side of the display.

This is WRONG and will destroy your display. The black bezel is 5mm wide, this is beyond the 1mm wide adhesive and into the LCD display and backlight assembly. Do not insert anything more than 2mm down the sides of the display.

Any further than 2mm and, like me, you will be looking at a very expensive LCD display replacement.

Thanks IFIXIT.COM for publishing an incorrect guide that has destroyed my display.
