Why do shops still claim to have working replaceable iPhone 7 Buttons?

It is more a story then a question.

I repaired a iphone 7 screen. Upon restaring it mentions an error with the homebutton.

Assistive touch went on . Strangely the fingerprint was still working and the haptic feedback also.

Missing the click function i tried to find a solution.

I ordered from 4 different shops button. Especially asking if they would work as a normal button without fingerprint just like the 5s,6 and 6s.

2 shops on Ali and 2 in the netherlands price between 2 and 12 euro's.

i can only conclude it does not work. The phone will not boot , stuck in a loop till the logo. One shop was convinced it should work and resend 2 buttons.

I tried normal swap

Recovery after swap

DFU after swap

But no result at all.

No button boots the phone but then you cannot do anything ;-)

WARNING:

DO NOT UPDATE IOS OR FACTORY SETTINGS WITH ONLY ASSISTIVE TOUCH AND/OR NO BUTTON. YOUR PHONE WILL BE A BRICK

I read a lot the past weeks but there is still no solution. I only come across error 53 , John Deern Tractors, Apple and other companies that locks you in when buying their stuff. I thought this sort of behaviour is not very democratic or giving confidence to customers. I always was a fan of android in terms of usability (connecting to PC and retrieving and deleting files to get more space on the phone ) but now even more :-)

TIP:

INSTALL GOOGLE PHOTO ON YOUR IPHONE BACKUP TO GOOGLEDRIVE THEN DELETE YOUR PHOTOS WITH THIS APP EVEN ON THE PHONE ITSELF WHEN ASKED. THEN GO TO THE IPHONE PHOTO AND WITH ONE CLICK YOU CAN EMPY RECENTLY DELETED :-)

Are there people around that no more about overcoming this button problem or inside apple info about turning this lock in around like they did with error 53 much appriciated.
