Assuming you are now facing Huawei ID and FRP Lock after doing hard reset or factory reset at your Huawei Y7p, don’t worry because this method works perfectly and you don’t need a dongle or box to apply it:
All you need is a Huawei Y7P Huawei ID unlock file, a SD card, Huawei ID & FRP flashing tools, USB drivers and USB cable.
Note that some Huawei administrations are not accessible in all countries. To get Huawei administrations like HiCloud, Themes, vMall, HiCare and HiGame, you should initially enlist and have a Huawei ID.
