If you get APKTOOL_DUMMY that's generally because apktool can't decode some of the information in the original APK and creates a 'dummy' value instead. Because there's no style called APKTOOL_DUMMY in public.xml (which essentially lists all the resources in the app) the APK can't be recompiled.

It's worth using a program like Notepad++ and searching the decompiled files for every style defined in public.xml. In theory, there should be two there that aren't used in any other XML files. Those should be the ones that the APKTOOL_DUMMY values are referring to. If you know which those are, you should be able to rename them in public.xml and styles.xml. Then your file should recompile. Hopefully.

@Ticklefish - close, but in order to check that you normally need to dump the resources with aapt, with something like

➜  2339 aapt d resources Huawei\ AppGallery_v10.2.1.300_apkpure.com.apk | grep 'INVALID'
➜  2339

There are no results, so the reason that dummy attribute came to fruition, must be different. I ran in verbose mode -v to see if anything stuck out and I spotted.

You can tell those resources start with 0x01 (or a framework resource).

So @MaroX97 what is happening is Apktool is trying to find a framework source for the styles class that is cannot find. When this happens there is literally nothing Apktool can do. I've debated putting in AOSP resources directly into Apktool to maintain pkgId 1 resources, but as you can see with the hundreds of flavors of Android - that would not be feasible or correct.

There is no bug here, arguably Apktool could die out here and instruct of missing resource, but I don't want to break execution for something that may happen.
