Hello,

This is exactly what I'm facing. After soft reset of my Lumia 430 phone that runs Windows 8.1 I got a screen that I must update. I updated to the latest version and I'm still getting that screen. Because of this I cannot enter into the whatsapp itself, otherwise I could simply backup my chats and reinstall.
