Hi Guys, replaced the display from one customer and fingerprint didn't work so I advised him to restore in DFU mode. Error 53, stuck. Customer was blaming me so I had to find a solution, here it is: 1. Be VERY CAREFULL removing the fingerprint cable stuck to the back of the LCD Shield. Seems we damaged it just a tiny bit, almost invisible to the eye. That caused the error 53. 2. The solution, connect a new cable cable (the long one stuck on the back of the LCD) and do the restore again. Before it stopped when it was about 50% in the restore and now it smoothly moved through. Hope that can help you guys as well. Gr. Arno
