Unknown error code during application install: "-24"

[kittybee]

Hi. So... a couple of days ago my phone crashed and did a factory reset on its own. Lost all contacts and other relevant data, yes. Some apps would reinstall but the others wouldn't because I kept on getting this: Unknown error code during application install: "-24". Does anybody here knows a fix?

Welcome to Android Forums.

What phone do you have (carrier, manufacturer, model, Android version)?
Is it root-ed?
Do you have an application installed that you authorized to do a Factory Data Reset remotely (like Android Device Manager or Cerberus)?

Which apps would report 'Unknown error code during application install: "-24" '? Try to download a genuine copy of apk for each of these apps and run reinstalling again.
