@essayn Firmware Finder apk. Settings > delete HWFF folder > exit. Dont setup proxy or touch anything else in settings. Back button then enter model number. If more than one result choose largest one and tick download only, nothing else. You will see one to three files, all you want is Update.zip. Open zip and move UPDATE.APP to a safe place. HuaweiUpdate.App.Extractor by Worstenbrood from XDA Developers. Done in 20 mins start to finish.
