Description: below, information on tablet repairs that can...

Steps:

1. sometimes the success of an operation depends on the right idea. In this case, the screen is completely destroyed.
2. in this case, both the digitizer and the matrix are completely destroyed. My idea is to remove these parts and replace them. It is worth making sure beforehand that the iPad is working (despite the broken screen). You can do this by connecting your iPad to your computer. If it is detected, it is safe to change the screen.
3. however, if your computer doesn't detect your connected iPad, it's likely that the damage is more than you think. In that case, find a good repair shop and consult the next steps.

4. Model 9 has a separate LCD display and digitizer.
5. when selecting a replacement digitizer, check that there is an adhesive applied. If not, one extra sheet will be needed.
6. because of the finely broken glass, be sure to wear safety glasses (you only have one pair of eyes and they cannot be replaced). Think about protective gloves if you need to.
7. Additionally: cosmetic sticks and some isopropanol (100ml is enough), tweezers (pincetce), a PH00 star screwdriver, a piece of thin plastic to disconnect the battery pins and a soft guitar pick - it will be perfect.
8. Small plastic blade will come in handy. The piece of plastic I wrote about above must be really thin but quite stiff. You can use a piece of neatly cut paper from a school notebook (non-conductive).

9. it is easiest to start from the place marked with a yellow circle. Then, along the purple arrows on both sides. Absolutely stop before the bottom edge!
10. in the place marked with a red rectangle there is a tape from the Home button and the Touch.ID function - ( attached to the glass ) You can't damage it (this item is unique)
11. a drop of isopropanol and a spatula or a thin, flat screwdriver will certainly help to overcome the every next few inches.
12. with a yellow circle I mark the Touch.ID tape which is running from the digitizer under the matrix. This bend is sensitive.

13. do not try to peel the button tape off the digitizer at this stage. There is a shortcut that will give you a lot of space for further work
14. My matrix is broken, I don't care about it. If yours works and you are not going to replace it - do not touch the display surface (black). Fingerprints are very difficult to remove. alternatively, you can use nitrile protective gloves (like me)
15. the shortcut I'm talking about is disconnecting the entire assembly. To do this, disconnect the battery voltage and remove the matrix and digitizer with the Touch.ID button tape
16. with red circles I mark the screws fixing the matrix

17. the northern screws are covered by isolator tape. Gently peel off (do not tear it - you will need it) until the screw is exposed. South screws may be covered by the black glue, don't worry about it. Just unscrew the screws - the glue will give slightly.
18. unscrewed matrix (4 screws) slightly lift it by the northern edge. Pay attention to the signal tapes connected to the motherboard

19. My matrix is broken, I don't care about it. If yours works and you are not going to replace it - do not touch the display surface (black). Fingerprints are very difficult to remove.
20. when you lift the matrix, under you will see the motherboard and connected battery. The red circle I marked a power supply piont, which should be disconnected at first. The yellow circle I marked the connection of the digitizer and screen to the motherboard.
21. the safest way to remove power from the motherboard is separating a power connector. You can do this by slipping a thin non-conductive layer between the power pins (especially the negative ones).
22. caution - too thick separating layer can lead to mechanical damage of pins and side current contacts. This is the most common tablet failure caused by unqualified personnel of unauthorized repair shops.

23. after unscrewing the cover you will see three fastened connectors: two parallel - it's digitizer and one perpendicular - it's a matrix. Unclip the connectors and remove the matrix. If it is damaged, as in my case, it should be utilized of. If it works and you're not going to replace it, make sure you put it away in a safe place.
24. caution - do not touch the display surface (black). Fingerprints are very difficult to remove.
25. a few more wires and one flat strip remain connected. Unless you're going to remove the motherboard (I don't see a need to do so in this case) you don't need to worry about it. Only the flat tape remains important - it's a tape of Home button and the Touch.ID function

26. the connector is a bit different than you have already seen in this device. Peel off the protective tape and pry the lock bar on the opposite side of the tape.
27. remove the tape from the unlocked port, peel it off the case and put it aside.

28. finally managed to disconnect the digitizer from the tablet. You can skip the next 10 and 11 steps if your digitizer is in one piece. If it's broken into thousands of pieces (like mine) read it carefully
29. the entire home button strip consists of several connected sections (some with a bit of electronics on board), a clicking button and an additional bracket that is absolutely necessary for proper operation.
30. the whole set consists of 3 elements: a tape with a button, a metal bracked and a button-sized round washer (in my case it was glued to the body of the button). Make sure the washer is not left on the glass. Thoroughly clean the entire assembly of fine glass debris and dirts.
31. glass particles left on the button elements will scratch and crack the new digitizer glass over time. Make sure everything, including the edge of the tablet, has been properly cleaned of glass particles and dirt.

32. be extremely careful at this stage. Remove any speck of glass from the adhesive surfaces or remove all remaining adhesive with a cotton swab and isopropanol.
33. glass particles left on the button elements will scratch and crack the new digitizer glass over time. Make sure everything, including the edge of the tablet, has been properly cleaned of glass particles and dirt.

34. particles of broken glass left on the contact surface of the housing, new digitizer glass and button tape under pressure will lead to scratches and subsequent cracks on the surface of the new digitizer glass. Make sure that the surfaces are absolutely clean and free of anything
35. don't forget to clear the table you're working on. Leftover particles of broken glass can scratch the case in a really ugly way

36. unfortunately, this step is necessary. More and more often we buy non-original spare parts (mainly due to the price but also due to the lack of availability of genuine spare parts). These, especially Chinese ones, are often incomplete or not working.
37. Connect the whole new set to the tablet and test their operation. If you do not peel off the protective films, you can easily return the purchased non-working items and request a replacement or refund. If the technical film is removed earlier, dishonest sellers try to blame us - the owners of the devices for installation faults
38. don't forget to remove the battery protection layer that has been inserted between the pins of the motherboard and the battery. Tighten the screw in the port to make sure you have full contact.
39. check the operation of the new elements, especially the entire touch layer. If you notice "dead lines", disconnect the digitizer and return it to your seller. Don't forget to remove the securing screw from the battery port beforehand and use the motherboard and battery pins protection

40. place the digitizer on a clean surface in front of you. Note that the inner touch side also has a clear protective film on it. Gently bend the area around the connection tapes (so as not to stick the tape to the foil but to the proper screen)
41. remove the tape protecting the adhesive on the tapes from the inside. This side should stick to the digitizer glass.
42. gently bend the tape to the surface of the digitizer. The glue is not very strong but should be enough for a moment. Cover the glued tape with the previously removed digitizer protective film (in the previous point). This will stop the tape from peeling off
43. do not press the adhesive tape. The concentrated connection paths of the entire digitizer in this place are less than 1mm. It's a really delicate and sensitive place. Pressing (possibly breaking) may cause dead lines on the touch surface (after all, it worked during the previous test :-) )

44. place the button in the intended place. Make sure once again that you have removed all possible dirt and particles from the glass of the previous digitizer
45. lead the cable along the edge of the digitizer layer in the left direction - parallel to the bottom edge of the screen. Whether the tape will overlap the digizer level (a layer with copper mini-wires) depends on the construction of the replacement shield itself. In the original ones there is room to leave a 0.5mm gap.
46. In my case, the button tape overlaps 0.5mm on the digitizer. Everything is OK.
47. put the home button bracket in the right place and stick it. In the original, the braket is additionally secured with a thin layer of hot glue

48. mount the metal Home button bracket so that the round distance corresponds to the micro-switch of the button - which is important for proper work of entire button (click function)
49. stick the rest of the button tape to the glass. In the case (like mine) where the screen adhesive is already placed on the inside of the glass, make sure that you do not stick the button to the film protecting the adhesive. Lift the foil protecting the adhesive and glue the button elements under it.

50. it's almost done :) Apply glue to the edge of the screen or the edge of the housing (depending on the type). If you already bought a screen with glue (like me) go to the next step.
51. Make sure you haven't lost the battery pin spacer that cuts off power to the motherboard.
52. a support for the screen would be useful - place the screen perpendicular to the housing and connect the Home button ribbon.

53. make sure once again that the plastic piece separating the battery pins from the motherboard is in the right place. Without this, the electronics of the tablet may be damaged when touching connecting
54. connect the digitizer (double plugs). The connection ribbons should be bent towards the inside of the tablet. When closing, tapes should push themselves under the edge of the housing.
55. set the matrix perpendicular to the housing and plug the connector into the port. You can screw a connecrors bracket. Remove the plastic cover of the battery port and replace the screw - it's time to test.

56. put the elements back in the right place, but do not tear off the foil protecting the glue and the surface of the screen. Check the operation of the screen, touch and button. If everything works, go to the next step

57. set the matrix in the right place and screw in the securing screws (marked with a green arrow). If the holes are not blocked, you can pierce the membranes with a thin screwdriver or other tool.

58. remove the protective film of the screen adhesive
59. remove the protective film of the digitizer
60. remove the protective film of the matrix (remember
61. remember that you cannot touch the surface without the protective film. The resulting fingerprints and marks will be very difficult to remove

62. set the tablet right edge up (do not stick yet). Closing the screen from this side, you will notice how the connecting strips slide under the edge of the housing. If you feel that they are curling ON THE EDGE - stop, go back to step - 17 - and adjust the position of the straps.
63. If the tapes have hidden under the edge, close the screen and press down lightly. The glue is strong enough to hold the digitizer to the edge. You don't have to use force.
64. Check the operation of the touch and the aesthetics of the entire connection (screen - aluminum edge of the tablet). I hope you are satisfied with your work.
65. Congratulations - you have just replaced the screen and digitizer in your favorite tablet on your own kitchen table (according to the mission of studionapraw.pl :)
