Fix icons green background issue caused by xposed (or any other UI app)

sorry for bad english.

first go to playstore and
download the launcher of your preference
(recommend nova or apex)

install the launcher

download Es File Explorer

on Es File, go to apps page, backup launcher apk,
uninstall launcher

go to system/app

backup HwLauncher6.apk and HwLauncher6.odex
and remove

go to your backup folder, and copy/cut
the downloaded launcher apk

paste it in system/app

rename it to HwLauncher6

now the launcher icon would look like the
default huawei launcher

exit Es File

now your downloaded launcher would be your
default system launcher

(the system thinks thats the default huawei launcher)

huawei themes still work (unless you have xposed resource hook active)

icon packs work too

if any problem or question just ask in comments.
