Error API_KEY_ANDROID_APP_BLOCKED

[guillaumegarcia13]

I recently encountered that error

GCM register request attempt 1 out of 100 has failed with Error=PHONE_REGISTRATION_ERROR
GCM register request attempt 2 out of 100 has failed with Error=PHONE_REGISTRATION_ERROR
Error during fcm_install: {

      }
    ]
  }

I assume some of the hard-coded parameters to access Firebase have been blocked.
Is there a way to generate new ones (as environment variables of some sort)?

I checked the latest APK and confirmed that the API key in Auth/fcm_receiver.py
has not changed, so no API key update is required.
Therefore, this error is more likely due to Google now requiring SHA1 for Firebase authentication.

This error can be circumvented by adding the following headers to the request within fcmregister.py:

• X-Android-Package: com.google.android.apps.adm (Package ID)
• X-Android-Cert: 38918a453d07199354f8b19af05ec6562ced5788 (SHA1 hash of the APK certificate fingerprints)

The SHA1 hash can be confirmed from pages like the following:
https://www.apkmirror.com/apk/google-inc/find-my-device/googles-find-hub-find-my-device-3-1-485-2-release/googles-find-hub-find-my-device-3-1-485-2-2-android-apk-download/#safeDownload

I've created a PR to resolve this issue (#93).

[rajeevkr945]

I can confirm this works.

[micbuh]

just tried @moons-14 fork. Unfortunately it fails in the same way.

[moons-14]

@micbuh In the case of my fork, did you use the code from the cert_sha1 branch?

[shodan65]

I had to use the chrome beta to make it work

[micbuh]

@micbuh In the case of my fork, did you use the code from the cert_sha1 branch?

no... I should have checked this...
I can confirm it's working.
Thanks a lot!

Used the code from the cert-sha1 branch and was able to get pass the API_KEY_ANDROID_APP_BLOCKED and successfully authenticate; however, no trackers are detected even after successful authentication

Unsure if this is related or not as this is my first time using this tool, so I can't attest to this working in a previous version
