iPad Air 2 has been walking around the planet for quite a long time, which means a considerable number of “lucky ones” managed to break it, fill it with something or even drown it. For the last two, we have the corresponding ones for rescue, for all the rest, who will certainly need to open their Air, this manual is intended.
When you try to open the iPad, you will run into great difficulties. Apple I decided to get rid of any screws and opt for glue. The extreme subtlety of the gadget requires sacrifice ...
Therefore, the only way to look inside is to heat the device with a building heating pad that has previously been in the microwave (however, a household hair dryer will do). Next, we hook the screen with a mediator or a plastic card, and raise it. Be careful, as there is a risk of damaging the matrix.
After successfully opening the iPad Air 2, you will notice that all the display cables are now in the lower corner on the side.
The appearance of the Touch ID sensor cable is in many ways similar to that of the new generation of iPhone.
Now we remove the FaceTime HD camera and the 8 MP iSight camera surrounded by a microphone. If you compare it with that of the iPhone 6 Plus, you can immediately notice a big difference. True, of course, it is still better than the previous generation of iPad Air.
The location and appearance of the headphone jack have remained virtually unchanged.
In the Wi-Fi model, the antenna is now at the top of the device.
The following markings can be found on the microphones.
M1300 5743 M1 334
M1300 5723 M1 334
We hasten to inform you that the logic board is still glued. Again you have to resort to heating. After removing it with disappointment, we observe that the Lightning connector is still soldered to the logic board.
Finally, we get to the chips!
The battery is no longer attached to the logic board and is ready to be removed.
After a full opening, only a lifeless shell with magnets remains for working with Smart Cover cases. Good news, the old cases still fit!
On a repairability scale, the iPad Air 2 gets 2 out of 10. It's obvious why the new product received such a low score. The only plus is the ability to remove the battery.
Here are 5 drawing and painting apps for iPad:
Price: 229 r.
The application allows you to quickly and easily create drawings for web projects and iOS applications. Let's start by creating a new project. On a blank sheet, you can add pages and pre-built site and iOS elements.
After dragging an element onto the project, by clicking on the element, it can be copied, cloned, and deleted. You can wrap an element in a group of multiple elements, and the iPad drawing app lets you change the properties of the selected element.
There is also a mode iPad connection presentations to big screens. You can convert the project to JPG, PDF or Bmml format (Balsamiq Mockups) or save it as an iMockups file. The application supports Dropbox.
Price: 299 p.
With this application, you can create complex geometric shapes, explore them, modify and calculate indicators. Shapes are displayed on a rectangular scaled sheet with a coordinate system. Each form has a set of custom properties (color, width, background, etc.).
The shape is automatically calculated and presented along with the shape properties. Some of them are editable, such as location points, line lengths, circle radius, etc. Documents can be saved to a local drive or iCloud. Export formats include PDF and images. Printing is also available directly from the drafting app on the iPad.
Price: free / 33 rubles.
With this drawing app for iPad, literally every user will become a graphic sculptor. The functionality of autodesk includes the creation of 3D models, their design, modification. You can become a design professional with this app.

Several color palettes, a powerful new gradient editor, and many other features. You can create detailed technical designs, floor plans, and diagrams using customizable measurements. Aligning objects is easier with Smart Direction.
Instructions automatically appear as you draw, move, and resize objects, making it easy to align the shape with other objects visible on the canvas.
Price: free / 649 r / 3290 r.
GraphPad is the latest in design, this application is useful for architects, engineers and other CAD users who need to draw and draft on the iPad. GraphPad is one of many new tech tools. drawing for iPad, but it has one unique advantage. For example, how do you move a point or vertex with your finger using multitouch.
- Fully laminated 9.7 inch IPS multi-touch LCD screen with 2048 x 1536 resolution at 264 ppi with anti-reflective coating
- A8X CPU with 64-bit architecture (it was rumored to be triple-core with a 1.5 GHz SoC), coupled with 2 GB RAM and an M8 motion coprocessor
- 8 megapixel iSight rear camera capable of recording 1080p/30fps or 720p/120fps video + 1.2 megapixel front camera with 720p video recording
- Fingerprint ID sensor + barometer + dual microphones + 3-axis gyroscope + accelerometer + ambient light sensor
- 802.11ac dual-antenna MIMO Wi-Fi + Bluetooth 4.0
- Memory 16, 64 or 128 GB
Step 2
iPad Air 2 marked the beginning of a new marking of models like A15XX. For example, this iPad Air 2 Wi-Fi model is A1566. Along with a new number, the iPad Air 2 introduces a new feature to the iPad series, the Fingerprint Identification Sensor (Touch ID).
If you're not familiar with this technology yet, Touch ID will allow you to unlock your iPad using your fingerprint, moreover, you can use it to "sign" your purchases in the iTunes Store, App Store and iBooks Store. The device is able to read the print from any angle and in any orientation.
Step 3
Last year, the iPad Air was as thick as a pencil. The new iPad Air 2 is even thinner this year! Seriously, 6.1mm profile is very impressive! Not only is it thinner than the previous iPad Air, it's also thinner than all previous iPhones. What other changes? For example, a slight offset of the dual microphone to the iSight camera of the iPad Air.
iPad Air 2 has become not only thinner, but also lighter.
We had high hopes that this iPad Air 2 would do without glue, we tried to find at least some screws on the outside. Apple managed to do without glue when creating an iPhone 6 the size of a tablet.
But no, we have to resort to iOpener. We will someday publish a detailed description of this "introductory" procedure.
Step 4
What then? Classic iPad opening using high temperature and careful opening of the tablet panel. The front of the new model is more durable than past iPads, but still flexes quite well when you try to peel off the glass. This can lead to breakage and no matter what part you would like to replace, because there is no other way to get inside the tablet. The only way to save money on such repairs is to contact suppliers of spare parts for mobile and tablets and purchase components at a wholesale price.
Step 5
After successfully opening the iPad Air 2, we notice that all of the screen cables are now at the bottom of the screen. Needless to say, this is a welcome change. In the previous version, the screen and digitizer cables were on opposite sides of the device, and it cost nothing to damage one of them when opening the device. Also, don't push the edges of the iOpener too far in, as it's easy to make a mistake with the iPad Air 2.
Step 6
The design of the Touch ID cable is similar to that found on the latest generation of iPhones. Having removed the home button, we found on it a single chip marked “Semiconductor NXP 8416A1 Touch ID Sensor”. Further inspection revealed even more chips on the front panel:
- Parade Technologies DP675 LCD Driver
- Texas Instruments TPS65143A LCD Bias Solution For LCD Panels
Step 7
Step 8
Our next step is an HD front camera and an 8MP iSight camera surrounded by a microphone. Compared to what we saw in the iPhone 6, we can't say it's the same as the iPad Air 2, but it's a significant leap in technology for the iPad line.
Step 9
The location and design of the headphone jack remains mostly identical. We say "mainly" just because of one little thing. It seems that the iPad Air 2 front HD camera's ambient light sensor has been split into 2 sensors, and one of them is now on the headphone jack.
Step 10
The antennas on our Wi-Fi model are now located at the top of the iPad instead of being below them. I wonder where the antennas are located in the iPad Air LTE version. Use the spudger to remove the antennas.
Step 11
In this assembly of devices, first we will pull out the microphone, then the light sensor and the power button. Then we pull out another microphone and two volume switches on a single cable.
Step 12
The following markings were found on the microphones:
- M1300 5743 M1 334 (microphone located on power button cable)
- M1300 5723 M1 334 (microphone located on volume cable)
Step 13
Unfortunately, the iPad's logic board is glued on, and we're back to the tried-and-true iOpener. After some tedious work, we release the fee.
Sadly, the Lighting connector cable is soldered onto the logic board. This means that if you need to replace the connector cable, you will have to change the entire logic board.
Step 14
Finally, we got to the chips on the iPad logic board:
- Apple APL1012 A8X processor with 64-bit architecture
- Technology Elpida/Micron F8164A3MD 8 GB RAM (per 1 GB) (1 GB x 2 = 2 GB total)
- SK Hynix H2JTDG8UD1BMR 128 Gb (16 GB) NAND Flash
- NXP 65V10 NFC Manager (as found in iPhone 6 and 6 Plus)
- Apple (Cirrus Logic) 338S1213 Audio Codec
- NXP Semiconductors LPC18B1UK ARM Cortex-M3 Microcontroller (Apple M8 Motion Coprocessor)
- Murata 339S02541 WiFi module
Step 15
The following chips:
- Maxim Integrated MAX98721BEWV Boosted Class Amplifier
- Broadcom BCM5976 digital converter controller
- Texas Instruments TI48WHXDP 343S0583
- Semiconductor Fairchild FDMC 6683 and FDMC 6676BZ (these two chips have been used in all tablets since the iPad 2)
- Bosch Sensortec BMP280 barometer and BMA280 accelerometer
Step 16
The iPad Air battery is now free of the logic board and ready to be removed. But it is again glued to the panel and requires an iOpener. Not bad, but it would be better to leave us at least a few tabs for a quick battery change. This battery is rated at 27.62 Wh, a slight reduction in power from the previous iPad Air (32.9 Wh).
Apple claims the same 10-hour battery life as the first iPad Air, so the battery is being used more efficiently. Although if reviews and earlier reviews are to be believed, the actual battery life is still reduced compared to the iPad Air 2 predecessor.
Step 17
After removing all components from the back of the tablet, all that remains is the Smart Cover magnets. Great news, last year's Smart Cover is fully compatible with the iPad Air 2. A small loophole in the annual upgrade and update of spare parts for tablets.
Step 18
iPad Air 2 repairability score: 2 out of 10.
The battery of the new iPad Air is not soldered to the logic board. When assembling the tablet, too much glue was used, which makes repairs very difficult.
The LCD screen and front panel are now glued together. This simplifies the "introductory" procedure a bit. But this design now increases screen repair costs and increases the risk of screen damage when the device is opened. The front panel is glued to the rest of the device, which can also lead to glass breakage when disassembling the tablet. But you can save on accidental breakdown by purchasing Apple parts in bulk from Optima Electronics.
iCloud- an Internet service created by Apple, which serves for the remote storage of data and the exchange of this data between connected user devices.The program works with iCloud "Find my Iphone". Wikipedia:
The Find iPhone/iPad/Mac application allows you to find any device running iOS or Mac OS, lock it, or remotely erase all data. For detection, you need to activate this feature on the device itself by entering the login and password from your iCloud account. There is no way to disable the feature without entering a password, so this can serve as a theft protection. To work, you need an Internet connection.
blocking
If the device disappears, the owner can go to the iCloud service and block this device. You can even send a message to your device's lock screen for someone to turn on the device.The most stupid thing is when the owner locks the device, but does not indicate their contact details in the message on the lock screen. Not for myself, not for people.
Reasons for blocking devices
Let's start with the most “It's not my fault. It itself ”and we will reach the most malicious.- You bought an iPad, created an Apple ID account for yourself, entered it on the device, but did not save your username and password. Some time later, you decide to reset your device or update it to iOS 7-8. And then iCloud will send you greetings in the form of an Apple ID request and a password that you have already forgotten.
- Someone bought an iPad, but he was too lazy to set up the tablet himself. Some “Nutyzhkomputershchik” or a store seller set up for him and did not transfer the password and login. Someone resets or updates the device - hello from iCloud.
- You buy the device by hand or online. You didn’t check if the old owner’s Apple ID was deleted from the device, the seller forgot to delete it or didn’t want to on purpose. Reset or update - hello. And some sellers sell it this way on purpose, then block the device remotely and demand money.
- You walked and walked and found an iPad. Its owner has already noticed the loss and sent you greetings through the iCloud lock screen. If found, it is better to return the owner for a fee. :) Especially the Wi-Fi model. There is no sense from her yet.
- Someone imperceptibly for the owner borrowed his iPad. He noticed, he blocked it.
- Someone noticeably and with malicious hooliganism borrowed an iPad from the owner. The owner came to his senses and blocked the iPad.

The rarest. Only an anonymous society of greedy unlockers has the schematics for the device itself. I don’t have good quality schemes, but what was had to be restored after scribbling by someone in Paint. The signatures of the resistors on the diagram cannot be read, therefore it is signed as 1, 2, 3, 4. Perhaps 4 is r1204, 1 is r1205.
On the Model A1490 (GSM), resistors 1 and 2 (both 2.2 kΩ) should remain on the board, remove resistors 3 and 4.

Useful information about other methods to bypass iCloud Lock
On the Wi-Fi version, you can "transplant" the NAND chip from an unlocked device. You can also transfer the NAND + modem bundle to the 3G / 4G version. Some, it seems, even put NAND + modems from the iPhone that are compatible with certain versions of devices on the iPad.It's all complicated and expensive.
Resistors are very small, so do it all carefully and soberly. Good luck to you!
P.S. My karma is negative. Therefore, I can not often write comments and the number of pictures in them is limited. I would be grateful if you tell each other yourself, otherwise I will have to wait a long time to answer at least 1 time.
