EDIT: I fixed it! It was more simple than I realised. I used the dload folder method. Placing the update.app into a folder called 'dload' on an sdcard. Then holding power, both volume buttons to initiate the update. Thanks for your help guys!! I tried to update the firmware and screwed up big time. It's a huawei P9 lite and I am really stressing over it Any help would be really appreciated since I can't seem to get help anywhere.
