It will throw exception "FileNotFoundException: .x509.pem"

What is that exception? I tried every method, I searched whole internet no single solution.

The purpose of attached APK signer is that you can build your very own personal keystore and save it somewhere for future use in case you require to upload your updated APK to google playstore,

Playstore will not let you upload updated APK if APK was signed using different keystores for each

keystore issue?
hi there i have used the tool to sign a zip file which is a firmware. However, i still get the E:footer wrong error when trying to flash the update.

I suspect that the keystore in the original files is not matching with the keystore i made up and used with your tool.

is there anyway i can make them match?

is this even the problem or am i completely stupid?

thank you very much

I am sorry to hear that but there is no way you can match two different keystores. If keystore file is lost, there is no way to either extract it from apk.

You do not have either Java Development Kit installed or you have not specified its path in the signer program

Thank you for this guide, it worked perfectly for me.

I decompiled an apk (using APK-Studio from XDA), made the changes I wanted (removed root detection), built the modified apk, then followed your guide here to sign and align the new apk. The modded apk installs and runs now, whereas before it wouldn't.

Thank you for the easy to follow guide and links to required files.
