Hello! I'm trying to make something relatively simple, but i'm doing something wrong. What i want to achieve is to change the stock battery icon with a circle with % inside. I managed to decompile LGSystemUI.apk using the latest apktool. I changed the pngs and edited the battery stats and chatging animation xmls. I'm not touching the .odex file since i don't have anything to change there. I recompiled the apk again using the apktool and zipaligned it. And here comes the issue - once i push it to the phone and reboot i get only desktop without navbar, status bar and lock screen. I don't get a FC but the Systemui is not loading properly. I also tryed to sign the zipaligned apk which resulted in constant FC from LGSystemUI, something which i don't get is the apk is not signed. I lost a significant amount of time recompiling and trying different combinations but the result is always the same - either fc or no fc but ststemui is not loaded. Can you do please help me with some ideas what i might be doing wrong?
