I mistakenly deleted PackageInstaller.apk from /system/apps on my rooted phone and now i cant install apks. Google play store doesn’t work on my phone and i cant use adb with a pc. I cant reinstall packageinstaller because package installer is uninstalled! I want to know how i can manually reinstall package installer by putting all the needed components in the correct places. I want to know exactly what packageinstaller does when installing an app so that i can do the same. Please respond! Thanks!
