Huawei P20 Pro Fingerprint sensor Replacement (Without removing the screen)

Hi guys fingerprint sensor on my Huawei p20 Pro stopped working but I didnt want to attempt screen removal as the chances of damaging the screen were high, but what if I could remove and replace the sensor without removing the screen at £6.00 a pop on ebay for a replacement sensor against a ton plus for a new screen, I opted to take a chance with the sensor, so I removed battery cover glass then all removable parts in the sensor area, have uploaded pictures to explain the procedure. Then with a little bit of vaseline smeared on the sensor ribbon I gently guided it between the frame and screen and it slid in easily, then a matter of connecting the sensor to the relevant connector and a cross of fingers and when checked the sensor was recognised by my phone and works flawlessly.
