I lost my .keystore file?

Question

Ok folks.. long story short, I was developing on a computer that I no longer have access to. I was able to retrieve the source code, but not the .keystore file used to sign and publish my application to the market (with several updates). Am I, and my poor users, out of luck if I ever want to update?

I know the password used to sign the key (at least it is one of three it could be), so can I create another? There must be a way around this.. what about a hard drive fail?

Now it is possible don't worry, here is the full and final steps to reset .JKS file.

UPDATE: As it states in the Play Console Help here (scroll to bottom), you should now already do step 3 before (create new .jks, convert to .pem) and only then fill out the form with the upload_cert and .pem file attached. This will make the support process easier and faster for you.

Step-1

Download the UPLOAD CERTIFICATE (file name - upload_cert.der) from your Google Play Store Console

Step-2

Go to this LINK https://support.google.com/googleplay/android-developer/contact/key?hl=en And fill the application form with your valid Email ID and upload the file (upload_cert.der).

Step-3

Now you will get the Email from support team, and they don't need your .JKS file but .PEM file here is the email Sample.

Step-4

to convert .JKS file to .PEM file you just have to download KeyStore Explorer

After replying the Mail, wait for 48 to 72 hours your keystore fill will reset.

Faced the same problem. I was trying to restore it via deleted files restoring tools, but it failed. So, there is no other way: you should issue another application.

Generally, the only advise that exists on keystores: "always back it up!"
