Whatsapp Android To iOS Importer

Migrate Whatsapp chats history from Android to iOS.

Caveats

• Media files and shared locations are not imported (got placeholders instead)
• Messages from contacts that changed ids (phone numbers) are not linked

Prerequisites

• Mac with installed Xcode and iTunes

• Decrypted msgstore.db from Android:

  • Download and unzip https://github.com/p4r4d0x86/WhatsApp-Key-DB-Extractor/archive/v4.7-E1.0.zip
  • Download http://whatcrypt.com/WhatsApp-2.11.431.apk
  • Put the downloaded apk in the tmp folder of the unzipped github extractor project. Delete LegacyWhatsApp.apk and rename the WhatsApp apk to LegacyWhatsApp.apk
  • Follow the steps from here:https://forum.xda-developers.com/showthread.php?p=81902381#post81902381 (you have already done the first part of the steps).

• Installed and activated Whatsapp on your iDevice

• Whatsapp.ipa of the same version (google will help)

Step-by-step guide

• Check that Whatsapp is activated on iDevice. You should see the list of group chats when you open the app. Most likely, there won't be any messages prior to moving to iOS. You can even send/receive a message or two to be sure that there is something to back up.

• Build the migration utility (I'll assume ~/Downloads folder):

  cd ~/Downloads
  git clone https://github.com/residentsummer/watoi
  cd watoi
  xcodebuild -project watoi.xcodeproj -target watoi
  

• Create an unencrypted backup to local computer (not iCloud) with iTunes. Find the latest backup in ~/Library/Application Support/MobileSync/Backup.

• Locate Whatsapp database file inside the backup and copy it somewhere:

  $ sqlite3 <backup>/Manifest.db "select fileID from Files where relativePath = 'ChatStorage.sqlite' and domain like '%whatsapp%';"
  abcdef01234567890
  $ cp <backup>/ab/abcdef01234567890 ~/Downloads/watoi/ChatStorage.sqlite
  

Explanation: the alphanumeric ID (abcdef01234567890 in the example above) you'll get after running the first command is the name of the 'blob', that contains Whatsapp database. Location of this file inside the backup depends on the version of iTunes used - it's either <backup path>/<first two characters of the blob ID>/<blob ID> or just <backup path>/<blob ID>. In our example this will be <backup path>/ab/abcdef01234567890 or <backup path>/abcdef01234567890.

• Extract the contents of Whatsapp.ipa (we'll need CoreData description files):

  cd ~/Downloads/watoi
  unzip ~/Downloads/WhatsApp_Messenger_x.y.z.ipa -d app
  

• Backup original database and run the migration:

  cp ChatStorage.sqlite ~/Documents/SafePlace/
  build/Release/watoi <path-to-msgstore.db> ChatStorage.sqlite app/Payload/WhatsApp.app/Frameworks/Core.framework/WhatsAppChat.momd
  

• Replace database file inside the backup with the updated one:

  cp ChatStorage.sqlite "~/Library/Application Support/MobileSync/Backup/<backup>/ab/abcdef01234567890"
  

• Restore the backup with iTunes

Troubleshooting

More TODOs

• Automate backup editing (skip manual ChatStorage locate/extract/replace)
• Better command-line parsing (better than none)
