I have been trying to seek for that one thread that could solve my issue which the title said it all. I have followed many guides & use multiple different tools, both on device & PC but to no success. Most of the threads would just say; "recompile after finished editing whatever you want". But that's definitely not the proper way. Some guides there were hints of keeping/replacing the Manifest.xml & META-INF folder, yes I kept it somewhere else & replace it just before I want to recompile, no it didn't work too.
One of the guides said decompile the APK, copy the *_src folder somewhere else & recompile it back right away, edit the copied _src folder & edit whatever you want. After editing, open/view the recompiled APK as zip & drag/drop the files you edited, yes it was recompiled successfully but when I apply it to the device it FC right away & were unable to boot up although I wiped Dalvik and Art Cache. One more example was, instead of replacing the edited files, this guide replaced the META-INF & Manifest.xml. The problem was I can't even get it to recompile successfully.
Something could be really wrong with me, my PC or my device, if only some generous kind soul would spare some knowledge to help this poor soul I would appreciate it very much, thank you for whoever spared the time for reading this, I hope my noobness made your day.
- Merry Xmas &
A Happy New Year
