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 the black bezel on the side of the display. Inserting the pick too far may damage the LCD.”
Unfortunately, you only know you have inserted it too far when you have, and you start seeing little bubble veins form between the glass screen and the LCD.
The adhesive can be very stiff/hard, and if pushing through it can result in the pick plunging into the LCD when the adhesive finally gives way.
Take your time, use alot of heat, and if you need to try and push the pick in, try and do so in a slicing motion along the edge, use the wide edge, or hold the pick so that your finger will hit the edge of the screen before the pick tip will pass the bezel.
Adhesive strips are only 1mm wide on sides. Up to 5mm wide top and bottom. I used the Isclack. Screen seemed ok bending without breaking. Worth looking for a photo of the replacement adhesive strips so you know what you have to separate. Be extra careful at the lower right corner where the cables are.
This is a failure of a guide as it doesn’t tell you to insert at a downward angle so you don’t potrude into the LCD… Now I have to spend more money to replace the screen as I pushed adhesive between the LCD and the screen even though I went no farther than a millimeter short of the screen...
can you open the right side if the left is too cracked to use a suction cup on?
This guide needs amending urgently.
You MUST NOT put the pick or whatever you are using more than 2mm under the sides of the screen, or you will cut through the adhesive tape securing the backlight assembly to the LCD glass.
This will push adhesive into the viewable area of the LCD and cause the backlight assembly to no longer be secured against the LCD fully.
I now need a new screen.
This line below from the guide is absolutely INCORRECT and will ruin your expensive display:
”Don't insert the opening pick any deeper than the black bezel on the side of the display.”
The black bezel is 5mm to 6mm wide; you MUST NOT insert anything to that depth or you will destroy your display. 2mm maximum!
thanks. will take this into account for my repair

I too damaged my display because of this absolute nonsense (The German version, which I used, still had this INCORRECT portion in it). I can't believe how long it took iFixit to update this, even though people have been reporting this for years on end. Sadly iFixit still haven't updated a variety of other things that are still at the very least high risk instructions. I just messaged them the other day, but they don't seem to care about or understand the remaining issues that this guide has. At least they updated one of the most severe things, but they just plainly told me 'I'm wrong' about the rest. I liked iFixit it so far, and I've worked on a variety of (difficult) repairs - but this experience was a very huge let down.
A few thoughts after opening a number of Mini 4’s.
1) if the display is warm enough you can squeeze the digitizer and LCD back together after a minor incursion with the opening pick and it will reseal.
2) I’ve started going in at the top just to the right of the camera (I use an iFlex to get in then switch to a pick). Then I run down either side with my fingers choked up on the pick so there only a mm or 2 sticking out. Usually after running down one side, I can get the display open enough to get the pick in behind the LCD when I do the other side

Reheat and reapply the iOpener to the left edge for a few minutes.
If your iPad is cold, consider leaving the iOpener on for longer than 5 minutes. The aluminum housing is a very large thermally dissipating mass and will quickly cool off the glass and make you have to start over and wait the 10 minutes to reheat. There’s a very slim window in which you’re able to insert the pick into the glass adhesive before it solidifies once again. I’ve been fighting with it for like 20 minutes following these instructions and it’s not working. You really need to leave it for longer than just 5 minutes to get the back housing hot too.
Heat is essential. I used a 3d printer’s heated set at 65 degrees. Chris Storer’s stip above saved me as you really need to let it sit for quite a while to soften the adhesive. Since I was doing a battery change, I heated both sides as the aluminum back is a huge heatsink that really sucks up the heat. Don’t try forcing it; if the suction cup isn’t pulling a gap in the screen, leave it on the heater for additional time.
Love the 3d printer idea, I hadn’t thought of that! I have used a heat gun as well but you have to be very careful to not use too much heat. Also watch for inserting the pick too far, it is really easy to delaminate glass from the display!

Insert a second opening pick alongside the first and slide the pick down along the edge of the iPad, releasing the adhesive as you go.
-
-
-
Leave the opening pick in the iPad slightly past the front-facing camera.
-
Take a second pick and insert it to the left of the camera, where the first pick just was. Slide it back to the corner to completely cut any remaining adhesive.
-
Leave the second pick in place to prevent the corner adhesive from re-sealing as it cools.

Twist the two picks at the top edge of the iPad to break up the last of the adhesive holding the display assembly in place.
-
Lift the display from the top edge to open the device.
"Twist the two picks at the top edge of the iPadTwist the two picks at the top edge of the iPad "
When I did this twisting motion, and I thought I was being gentle, one of the picks cracked nearly in half. That adhesive is very strong! I probably did not cut into it far enough before applying the twisting to open the screen.

Remove the four 1.2 mm Phillips screws over the battery/display connector bracket.

-
-
Remove the battery/display cable bracket.
Is it the end of the world if the bracket is not reinstalled, will the device function normally or will it eventually have issues with the connectors coming loose following shock?

Use the flat tip of a spudger to disconnect the battery connector from its socket on the logic board.
When i was starting to disconnect the lcd to the board i hit the black film and it lit and now even the new display wont display anything how to fix it? The black film near the lcd connector.

Remove the display assembly.
Ich habe eine Bücherstütze benutzt um das Display in senkrechter Position zu halten, während ich die vier Schräubchen gelöst habe.. So zieht man nicht so an den Flexkabeln….!
Because the 3-piece adhesive strips shown in the Display Adhesive Application Guide link were different from iPad Mini 4 Adhesive Strips (item code IF316-013-1), it wasn't easy to figure out the exact location of the bottom adhesive. It would be helpful to include a separate application guide or an additional picture showing the exact location of each strip) on the guide.

Use the pointed tip of a spudger to flip up the retaining flap on the home button ZIF socket.

Use a plastic opening tool to pry the home button bracket off the display assembly.
The tip about the high-bond tape is great, but high-bond tape is something that should be mentioned at the beginning in the list of supplies we need. Because I have the whole thing taken apart, and now I’m told I need something that I don’t have on hand. So what am I supposed to do, just let everything sit around open, until I get to the store to see if they have some high-bond tape?

Is the piece of tape connecting the HB cable to the bracket important?
Home Button still does not work after home button transfer and digitizer replacement.
there is a tiny black circle on the actual button underneath the kapton tape. if that isnt properly lined up it will not depress properly. also if the collar isnt perfect the home button will not sit correctly and popout. its a pretty crappy design by apple.

It took me several attempts - but I eventually got mine to work perfectly. I had put glue on the bracket - since there was glue on the old one - but that made the gap too wide, so it wasn’t seating the home button right. I also had a replacement that had a slightly bent plug for the touch - so it wasn’t seating properly and the touchscreen was not consistent. I eventually got it all seated (the connector and the home button). Then it worked like a charm. Thanks for the guide.
