decompile huawei android system app&apk

[Mr.reCoder]

Hi all,

I want to de-compile and reverse Huawei android applications for example it's File Manager app to find how 'SafeBox' feature works. to be clear SafeBox is a feature that we can protect files with password.
the problem is ApkTool or other decompilers can't process and raise error.

java -jar apktool_2.1.1.jar d -f safebox.apk

ApkTool output:

Exception in thread "main" brut.androlib.AndrolibException: Multiple resources: spec=0x7f0b0166 string/tab_item_bookmarks, config=-es-rUS

Here is a thread about it but problem does not solved. using -r switch is useless because main class 'resources.arsc' remains untouched and does't decompile.
here is my apk:
