"Is iPhone 8 home button replaceable?"に関する回答Since the home button’s touch ID is paired to the logic board, you cannot change it and expect the button to function as touch ID any more. It will work as a plain home button though. The initial question had to do with the home button being cracked, not the flex cable. In order to answer the question, you have to take a look at the question the way it was asked. I repair iPhones on a regular basis. I see all forms of issues with these phones. If the crack is not interfering with anything, I would not change it, especially if it is just an aesthetics issue. The other alternative is to locate a logic board with a matching home button. That can generally be gotten relatively inexpensively by going to eBay and finding a phone 8 with a broken screen that is for sale. Then it would just take someone like me or another repair tech that knows how to change it out, to swap the screen over to the other phone.

"smartphones/tablets repair training needed in the United Kingdom"に関する回答I am certified repair technician and work for myself as well as a company called iCracked. iCracked has training videos available to watch to learn how to do the repairs.

Each model is different so it is important to make sure you are looking at the correct one for the device you are working with. It is also imperative that when you are working with these devices, you take care not to damage any of the tiny flex cables or their sockets. Let me know if there is something in particular you would like to view.
"MacBookPro does not power up on AC power or battery."に関する回答I also have a 2007 A1226 and had the same problem. It turned out to be the logic board. I am a certified technician so was able to diagnose it myself. After trying the hard reset (removing battery and unplugging from power, holding the power button down for 30 seconds, replacing battery into its place and plugging it back into power) and getting nowhere, I ordered a used and guaranteed working board from eBay for about $119.00, my Macbook Pro was back up and running with no more issues. I am still using it. In fact, I just upgraded the RAM to 4GB and it doubled the speed. Chances are, your logic board is bad.
