-
-
Heat an iOpener and apply it to the left edge for two minutes.
-
-
-
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.
-
-
-
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.
-
-
-
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.
-
-
-
Continue moving the opening pick down the side of the display to release the adhesive.
-
If the opening pick gets stuck in the adhesive, "roll" the pick along the side of the iPad, continuing to release the adhesive.
-
-
-
Take the first pick you inserted and slide it up toward the top corner of the iPad.
-
-
-
Reheat the iOpener and place it on the top edge of the iPad, over the front-facing camera.
-
If you have a flexible iOpener, you can bend it to heat both the upper left corner and the upper edge at the same time.
-
-
-
Slide the opening pick around the top left corner of the iPad to separate the adhesive.
-
-
-
Slide the opening pick along the top edge of the iPad, stopping just before you reach the camera.
-
As you reach the front-facing camera, pull the pick out slightly and continue sliding it across the top edge.
-
-
-
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.
-
-
-
Insert the previous pick deeper into the iPad and slide it away from the camera toward the corner.
-
-
-
Leave the three picks in the corners of the iPad to prevent re-adhering of the front panel adhesive.
-
Reheat the iOpener and place it on the remaining long side of the iPad—along the volume and lock buttons.
-
-
-
Insert a new opening pick and slide it down the right edge of the iPad, releasing the adhesive as you go.
-
-
-
Continue sliding the opening pick down the right edge of the iPad, reheating the edge using an iOpener if necessary.
-
-
-
Leave the opening picks in place and reheat the iOpener.
-
Set the reheated iOpener on the home button end of the iPad and let it rest for a few minutes to soften the adhesive beneath the glass.
-
-
-
Insert a new opening pick at the bottom right corner of the display, below the last opening pick you used to slice down the right edge.
-
Rotate the new pick around the lower right corner of the device.
-
-
-
Slide the pick from the bottom right corner along the lower edge of the device. Stop about half an inch shy of the home button.
-
-
-
Insert a final opening pick at the lower left corner of the iPad, directly below the existing one.
-
-
-
Continue sliding the pick at the lower left edge of the display toward the center of the iPad, until it is roughly half an inch from the home button.
-
-
-
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.
-
-
-
Remove the four 1.2 mm Phillips screws over the battery/display connector bracket.
-
-
-
Use the flat tip of a spudger to disconnect the battery connector from its socket on the logic board.
-
-
-
Use the pointed end of a spudger to disconnect the display data connector from its socket on the logic board.
-
Use the pointed end of a spudger to disconnect the digitizer cable connector from its socket on the logic board.
-
-
-
Reheat your iOpener.
-
Lay the iPad face down on your work surface and place the iOpener on the rear case, where the lower edge of the battery is.
-
-
-
In the following steps you will be cutting the adhesive under the battery, and prying it off of the rear case.
-
The adhesive is laid out as shown in this image: two strips along the long edges, and two shorter strips perpendicular in the center.
-
To avoid damaging the battery, use plastic tools, heat, and patience. Do not puncture, bend, or overheat the battery.
-
Do not pry near the logic board, you could damage your iPad.

-
Insert the corner of a plastic card between the lower end of the battery and the rear case.
-
Press the card until approximately an inch and a half is underneath the battery.
-
-
-
Insert a second plastic card between the battery and first card, this time with the card edge parallel to the battery.
-
Again, press the card in until about an inch and a half is underneath the battery.
-
-
-
Insert a third plastic card between the first and second ones, this time aligned with the left edge of the battery.
-
Continue to cut the adhesive under the battery until the battery is freed.
-
Reheat and reapply your iOpener when prying becomes difficult. Be sure to wait for the iOpener to cool between sessions.

This guide is great for disassembly. I’ve just successfully removed the battery from my device by following these instructions. However, it does not provide any guidance for applying the new adhesive strips before assembling the screen. For that reason, this guide seems incomplete.
[can’t edit the guide]
Cleaningoff the old adhesive:
Remove the old adhesive from underside of the glass and the edges of the case. This was the most time consuming part. Took 2-3 hours, because the original adhesive was really gummy and i didn’t want to damage any parts with harsh solvents. (I used a series of methods": citrus oil adhesive remover, methylated spirits, sticky tape stick and lift off.)
Making sure the edges of the glass and case are spotless ensures a good result when applying the new adhesive strips. New strips can be gently applied, peeled back and reapplied to make 100% sure they are in the right place. If adhesive residue is still present the new strips could get stuck in the wrong place and be impossible to reposition.

Reassembly:
Replacement double sided adhesive strips are applied to the case first. Figure which strips go top, bottom and sides. Start with the top or bottom corner. Apply the side strips last so you can figure which side is which.
Make sure the front camera and its window are clean. Use a strong magnifying glass and air duster. You won’t be able to get any dirt out unless you have more adhesive strips to use.
When you are ready to assemble, peel the backing off the double sided adhesive.
Support the screen at 90deg to case. Reattach cable connectors. Attach new battery connector then carefully position new battery with exposed adhesive into position in the case.
Attach connector clamp plate with 4 screws.
Carefully position the screen in case starting from the bottom edge. When it fits all the way around, press firmly round the edges to seal.
The guide is rated at a medium difficulty, which is out of step with a few iPhone battery replacement guides that are at a hard difficulty. Compared to the iPhone, the iPad is significantly more difficult to service. Even though there are few steps, it’s far easier to damage the device.
I’d rate it the hardest repair in earth!
