WhatsApp Google Drive restore fails I migrated to a new phone yesterday (Nexus 5 -> Pixel 2) and wanted to restore my WhatsApp chat history on the new device. I've always used the Google Drive backup feature, so I thought this should have been relatively easy. However, during the restoring process, the progress bar gets stuck at 31%. Some minutes later, the app informs me that restoring the messages failed.

What can I do? The Google Drive backup file seems to be corrupted, so I also made a manual copy of the msgstore.db.crypt12 file, so that I could maybe use that in order to restore my history. However, the steps listed on the Whatsapp website (https://faq.whatsapp.com/en/android/20887921/) do not work for me, since it always tries to restore the backup found on Google Drive.
If your old device is with you


Delete WhatsApp backup from Google Drive. See steps from WhatsApp FAQ
Redo Google drive backup manually (Settings &rarr; chats &rarr; chat backup &rarr; Google drive) and restore


That will create a fresh backup  so corruption is ruled out, though would take longer

Old device not with you but you have copy of database file


Uninstall WhatsApp
Install Whatsapp and  on successfully activating it, immediately disconnect from Internet
Copy the database file into the same folder location from which you copied and restore
