Question: is a pentalobe screw the same as torx

Answer: No, Huawei used pentalobe screws for the Huawei P9, a decision criticised by Kyle Wiens writing for Wired, because using pentalobe screws instead of standard screws like Torx, makes electronics more difficult to repair. Its successor, the Huawei P10 also used pentalobe screws to secure the back cover to the phone.
