Hello I having serious problems with my phone I cant download anything from the play store anymore because every time I get an error saying "insufficient memory" even though i have enough internal and external memory. I tried to hard reset the phone but the only thing that come up is a white screen that says "QPST DOWNLOADER Key Pressed" and that's it and when I factory reset the phone from the settings menu it doesn't do anything but delete everything on my sd card. so i decided to download the original firmware from the huawei homepage with the tfupdate.img but when I place it on the SD Card and do the software update it says that it cant find the update and resets. Am I supposed to place the tfupdate.img somewhere else on the sd card? I seriously need help because I m going crazy.
