I just ran across this, and thought it might be useful...? It's called Checkey and this is what it said on Google Play: Checkey is a utility for getting information about the APKs that are installed on your device. Starting with a list of all of the apps that you have installed on your device, it will show you the APK signature with a single touch, and provides links to virustotal.com and androidobservatory.org to easily access the profiles of that APK. It will also let you export the signing certificate and generate ApkSignaturePin pin files for use with the TrustedIntents library. Now I know not a whole lot about .apk files or file signatures and the like, but I do know file signatures keep me from flashing anything to my ridiculous, urootable phone (ZTE Speed). I thought I would ask about it here since there are some brilliant minds around that do know about these things. My question is: can this Checkey app somehow assist in passing signature check and flashing something through the stupid default recovery. I am guessing that it won't.
