Well, simple. I want to downgrade an app that has been accidentally updated. I've already read this question but it didn't provide me with a straight instruction. I have the APK I want to downgrade to so that question is unhelpful to me. It's not a test package (saved from Google Play) so option
-t doesn't make sense.
Things I've tried so far:
Run in a terminal (with root)
pm install -r -d old.apk
Use adb on a computer
adb install -r -d /path/to/old.apk
Brutally replace the apk in
/data/appand manually run
dex2oatto force compile it
All of above were to no avail. So I'm quite bothered about this.
I don't want an answer telling me uninstall the new app, then install the old one. I want to retain app data without backing up.
