Chosen Solution
I do a lot of phone repairs and I have some customers who tried replacing the screen on their iPhones by themself and brokr their home button (mostly the flex cable). Is there any possibility to get Touch ID working again without getting it repaired or replaced by Apple?
Literally not possible if you replace the button. It is possible to splice the broken home button back together if you have the skills. However there is no “chip” on an iPhone 6 home button. The only chip is the sensor chip fused to the sapphire face of the button, it is not possible to remove the chip from the button or extract any data from it.
I actually got a new one to work , I first disconnected the battery , disconnected the lcd , battery back on let it start up connected to a computer so you know when it has started up , then disconnect battery again , on the lcd disconnect the home button , then reattach the lcd , let it start up then shut it down again , connect the home button again and start up , then shut down and restore in dfu mode , then it will work , it basically rewrites the the code for the home button , I have done this on many many phones now with 100% success , hope it helps
Not that I have found and I’ve for sure tried. Best I can figure out is there is a chip in the Touch ID button that is paired with the logic board at the factory. That information is stored somewhere at board level, since a wipe/restore doesn’t reset it. Touch ID is pretty freaking solid security. I’ll give Apple a win on this one.
Unfortunately not (that I’m aware of). It is linked to the processor with a unique ID, so if both do not match, touch ID will not work. Apple did this for security reasons.
There is a way to keep the touch ID when reparing a iPhone home button. I refurbish phones and sell then on eBay. I have a bunch of home buttons and mixed them up and needed to find the right home button for the phone I was working on. I called Apple and they told me it could be done, but never got to tell me how, because I had to hang up and really I just thought the representative didn’t know what she was talking about. Well, that night I was fixing a phone with a black screen and just grab any button to test it and I put the phone in recovery mode and after I started to set it up the finger scan didn’t fail and I was able to use the Touch ID. The they was I had used a white button and the Touch ID was working and it couldn’t have been the original since my screen was a black screen. I called Apple again and was told that yes it should work. What the rep explained to me was that some companies don’t put the correct hardware on the home buttons they sell to save money, but if you purchase a quality one it will be able to reset the Touch ID to work by doing a full system restore in DFU mode. So who knew you can restore the Touch ID it just depends on the home button you purchased. They did say that the Apple Store and Best Buy can repare it for you and keep your Touch ID.
Don’t ask how I found this out, but the chip in “official” TouchID buttons isn’t actually OTP after all. Its actually an e2prom but with the external write voltage line routed through a cell fuse so when written it gets “Zapped” and goes open circuit or at least very high resistance in order that any attempt to rewrite it would then fail. The way to fix this would be wiping the chip with X-rays. Needless to say it would be dangerous but UV light may work as it has done with many smaller chips of which this is likely to be. Cell size is probably in the micrometre range so should be feasible with something like a Cool-X or similar.
What if you transfer original home button from other iPhone 6, will touch ID work?
Hello, just to let you know how.. My Home button on my iPhone 6S cracked, and I needed to buy another one. I got one from eBay, for around 5$. Have installed it, and its working just fine. Except Touch ID. I tried with restore in DFU mode, as some users here suggested, but had no luck to get Touch ID to work. Maybe its possible just with original home button from Apple. If someone found the way to get Touch ID to work after home button replacement, please let me know.
I replaced screen on my iPhone 5s Touch ID failed luckily had the flex of original fingerprint scanner put that back on the phone Viola was working again, can definitely say it’s chip pairing with logic board. Got a iPhone 6 Plus to try on next will let you know the results soon
apple would have to swap your home button, I’ve even tried an oem iPhone 6 home button and put it on another six but Touch ID will only work with the home button the logic board came with
So all you guys asking about “does the 5s have a storable chip info” The thing is, imagine an abacus. You have three reds and then three blues. Of course it is a row of chips reading 1’s and 0’s. But the chip reader inside the phone sees the three red and three blue and says ok. It is hard wired, in chips. It is not a readable programme as such the chip just read a series of chips under the home button, it then does it’s thang and says yep, ok that’s the right chips in the right order. Maybe to expand a little, there is an algorithm that , after the chip on the home button is “read”, it puts the algorithm into play and says yep, 37 that’s the one. The bottom line is, there is no programmable information to be stored
i have ip6s 64gb MKQP2J/A, i check that must be silver 64gb, but my iphone are GOLD with gold ring around the home, touch id workss fine! strange enough huh? any idea what s going on with my iphone?
hi, I have the same problem to. But there’s no sense in paring the original touch button with CPU since the fingerprint info is located somewhere in the logic board. With some internet search, I’ve been able to find some solutions, just entering in DFU mode and reset the iphone, or disconnect the power to flush it. Could be luck or not but since they did it, it worth a try.
Why to make things complicated, my Ipad works with the finger print of my Wife,s Finger, so every time want to use this Ipad Touch ID , she should be there for me ,???
If anyone happen to come across my situation, do let me know whats the best way to solve my situation. i really have problems regarding with my iphone 6 home button where specifically it’s completely spoilt. And i remember having a spare of an iphone 6 but only its motherboard(internally) damaged. No damages externally. Mainly, the reason to why i wanted to do this only because of my spoilt touch id and the other spare iphone 6’s touch id works perfectly fine. is there any possibility of replacing my current motherboard to the spare one so i can have my phone work complete fine with working touch id, functioning motherboard and other relatable parts that is function, specifically works like a brand new iphone 6.
My phone is iphone 5s. what if i get the working home botton of iphone 5s and i tranfer it into another iphone 5s.can i used the touch id again
Does anybody know how much a home button replacement costs at the Apple center? And is Apple Care specifically required for the replacement?
If you transfer the original home button it will definitely work. So if you take it to a store to fix the screen make sure you tell them to switch the home button, so you can keep your touch assist
There must be some method of programming new touch id since there is a QR code printed over the socket. I strongly beleive this is the clue. But how? I have no clue!
Hi, does anyone know which chip it is on the flex cable that is paired to the logic board? I have the old flex cable but it’s ripped so was thinking of desoldering the old chip and put it on the new replacement home button flex cable. So which chip is it ?
Firstly hello, Hope you guys can help as it’s similar to all above questions so thought I would ask here: Can I use another ribbon from another 6S (non OEM) as a replacement, but keep the existing original button, would the button id work? Thanks Ben
If you replace your home button it will work but touch I.d will not work.
Any other damage for the iPhone would be estimated around the same cost. So for the home screen by itself the estimate is $ 169 but “other” damage is estimated at $ 349 From Apple Tech Support
My iphone 5 cracked and my home button has fallen off. The homebutton however is still in good condition just that its broken off from its cables. Can i still fix the screen, whilst reviving touch id using the original home button? How would it connect to the replacement lcd? Give me ur takes on my issue pls.
A good chunk of phone repair stores have a machine that pairs your home button with the phone. Apple charges $80 and other stores will too because apple makes the machines that they can buy faulty so that they have to repair it and it’s expensive.
Yes this is posible https://www.youtube.com/watch?v=8IjC7rbH…
