Fails to install legacy WhatsApp on OnePlus 3T, Android 7.1.1 #4

Open CoDEmanX opened 7 years ago

CoDEmanX commented 7 years ago

I successfully retrieved the unencrypted WhatsApp databases from my old phone using the extractor, but I couldn't do the same on my new phone.

The reason why it fails is apparently a problem with installing / downgrading to WhatsApp 2.11.431, which makes all subsequent commands fail (because no WhatsApp is installed on the phone at that point):

failure [INSTALL_FAILED_VERSION_DOWNGRADE]

I also tried to download the legacy apk on the phone and install it there, but it fails as well.

Is there any way to fix this? Or can the legacy version simply not run under Android 7.1.1 anymore? If so, is there any other way to backup the data without rooting the device?

My OS: Windows 10 64bit Extractor: latest master of today

I am on an LG G5 with Android 7.0, It doesn't work for me either. I have exactly the same problem. WhatsApp 2.11.431 can only be installed if the data folder is removed.

Info: Phone: Xperia XZ F8332 Android 7.1.1 Build number 41.2.A.7.35

This post https://github.com/EliteAndroidApps/WhatsApp-Key-DB-Extractor/issues/10#issuecomment-386794491 offers a workaround if you can get hold of a spare Android 6 device to extract the key.
