Hey Where is the most important layout located where the touch ID is programmed? Centrally under glass or on tape (AD7149)? I have a problem with iphone 7 with the button pressed home can not start. He resets and fools when I hail him. The button is slightly damaged from the outside, which can...

AD7149's soldering will do you no good because it has nothing to do with touch id. This system is replaceable and it is replaced by min: if the return button does not work and the touch id works, or someone has damaged the system mechanically. The substitution of the new home tape can not help you either, because the virtual home AssistiveTouch will automatically start on the screen and the button will be a dummy. I have seen recently that the Chinese have invented a special flex thanks to which the new home button ($ 50) will work, but I have not tested it yet and I do not know if it works in general.

But lime

In older people, you could put in a home for PLN 10 and act, only the touch id was not there

Which element in this whole home / touch id system is unique and its damage crosses the further functionality of the home / touch id function?

sensor under the glass circle?

RafalB · Answer

Yes, a telephone store like God / Apple has ordered and for a fee exchange with a panel for an authorized service site, for example iMad, Cortland. You will not get over anything as the sensor is hit. For Home itself, you can replace the Chinese mechanical home on the flex switch.

Is there any difference in functionality if I connect Chinese for 20 PLN and I do not connect any of them at all?

RafalB · Answer

It is, sometimes the phone does not want to run at all with such a Chinaman, the original from the disassembly is definitely better.

B_B_Nation · Answer

But I'm talking about whether there is a difference when there is something connected - Chinese / original from another phone and if there is nothing.
If it only does it for the end cap, I can cut the tape and change it ...

RafalB · Answer

Update IOS to 12 and cut the tape Seriously, it normally runs, i.e. quickly, and activations embrace through 3utools or iTunes and voiceover.

Hello, I have a question when it comes to a damaged Home button in IPhone 7 whether the purchase of the recovery of the entire screen along with the home button will do the trick?

B_B_Nation · Answer

It does not do the trick, because the home button with the fingerprint reader is assigned to the iPhone's motherboard (it's unique) Only the official service can reprogram such a button by exchanging it with the display.

RafalB · Answer

Just like the above colleague wrote. it can not be changed in the entire 7 and 8 TouchID series. Interestingly, you can easily save NAND, the new serial number of another TouchID, but it does not give you anything.
It is also not possible to give another serial number in another TouchID. The circle closes.

The kit is available on the Chinese Ali [/ Youtube]

Hi, I, in turn, damaged the plug from the Home Button tape. Will re-soldering the item from the link below allow me to continue using Touch ID?

Sławosz(+) · Answer

Yes, it will help .. However, you have to connect a dozen or so paths with each other, and it is not that easy, even with the convenience shown in the photo.

For the sake of clarity Ladies/Gentlemen - that is, you can replace everything except... A: We throw out everything as long as there is a sensor that is functional and paired with the iPhone's board. B: We're throwing out everything, but the sensor and this system must remain functional.

bert_studionapraw · Answer

Hello, version A is enough. The ad7149 chip is responsible for the pressure simulation, it is not identified.

kosodrzewinkowy · Answer

...that's what I meant - thank you very much!
