Collectively these changes enable Google Messages to verify the phone number via UPI and retrieve the provisioning document.
In my testing, setup progresses through verification, provisioning and reaches a connected state in Google Messages.
The remaining failure occurs during Tachyon registration. One possible cause is that the final DroidGuard

Description
This PR bumps the spoofed
gmsVersionto 25.19.31.By using a script that patches the reported
com.google.android.gmsversion in the request payload and performs a binary search, I determined thatmobileconfiguration-pa.googleapis.comonly begins dispatching UPI-enabled configurations when the reported GMS version is ≥ 25.19.00.25.19.31 was chosen as the smallest bump above this threshold that corresponds to an actual released version.
