My iPhone 16 Pro Max (iOS 26.3.1) lost its entire WhatsApp chat history after I accidentally deleted the database. I do have an iCloud backup that predates the loss, but my own attempts to restore it have failed. I need the full chat archive back, including every photo, video, voice note, and document that was originally attached. Restore iPhone 16 Pro Max iOS 26.3.1 WhatsApp Chat Database. Delete WhatsApp by mistake, and when reinstalling is asking for a Passkey, which is somehow stored in "Passkeys", but unable to de the actual Passkey. Other option is the 64-digit encryption key. Unable to turn off End-to-end encryption What I expect from you • Extract the WhatsApp data from the existing iCloud backup without overwriting any current phone data. • Restore (or re-inject) all chats and their media so they appear natively inside WhatsApp on the device. • Preserve original timestamps, contact names, group memberships, and file integrity. You may use whichever specialist tools or forensic-grade utilities you prefer, provided the recovery is safe and the device remains fully functional afterward. A short remote session is fine if direct device access is required; otherwise, an exported .zip or .crypt14 file that I can import myself is acceptable. Deliverable is successful restoration verified on my phone. If full in-app restoration proves impossible, I will accept a complete export of all chats and media in readable form as a fallback. Please outline your method, estimated turnaround time, and any prerequisites so we can begin quickly.
