Adb install [username] - failed [INSTALL_FAILED_ALREADY_EXISTS]
Firstly, I know this has been asked many times, but I've tried all of these answers and still no luck. Let me explain.
I have 2 apps, 1 stock app and one with fino tool added (sysdream / fino). It's all properly packaged and written correctly, but when I try:
adb install app_fino.apk
Failure [INSTALL_FAILED_ALREADY_EXISTS]
And adb install -r, which is obvious when I added fino to it and retired.
adb install -r app_fino.apk
Failure [INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES]
Other answers said "Uninstall" and then install the new app again. So go to Apps> All> Uninstalled
... Rebooted phone
adb install app_fino.apk
Failure [INSTALL_FAILED_ALREADY_EXISTS]
Anyone ideas?

If you still get the message INSTALL_FAILED_ALREADY_EXISTS
even after
adb uninstall com.your.packagename
The application may still be present on the system partition and therefore cannot be uninstalled with adb uninstall
. To fix this, you need to uninstall the original system app as well (can only run on the rooted device):
adb shell
$ su
# mount -o remount,rw /system
# cd /system/data
# rm OffendingPackage.apk
Note that the package names in the system folder do not necessarily follow the convention com.your.packagename.apk
. So you might need to look a little at the correct apk.
Finally, the adb reboot
device before trying to install it again.
