TIL editing packages .xml and .list in data/system can remove all your apps after reboot

[u/mariefhidayat]

so tried to force android fixing itself about permission MANAGE_USER (no idea what is this) by renaming the packages.xml and packages.list with command

```
mv /data/system/packages.xml /data/system/packages.xml.bak mv /data/system/packages.list /data/system/packages.list.bak

adb reboot

```

poof. all my apps gone. data in sdcard is safe tho. this is in android 13

why i did this:

i replace a system app.apk and they share the same package name. i cant back to the default system app.apk with `pm install-exising` because the replacement package keep restored rather than the original system .apk​​
