If you're having issues restoring your chat history, it may be due to one of the following reasons.
• The Import chat history option does not appear
From LINE version 9.1.0, there is no longer a feature to back up and import your chat history from inside a chat. If Import chat history does not appear, you won't be able to import chat history saved on an SD card or LINE Keep.
• You didn't download the backup file from Keep
If you saved the backup file to Keep on LINE, you'll need to download it from Keep and save it to your new device after transferring your account.
• The backup file wasn't saved in the right location
Files created by selecting Back up all data are saved on either an SD card or your device.
If you're unable to import (restore) your chats, you'll need to manually move the relevant file to the folder titled "LINE_backup" on the device you want to restore your chat history on.
Please use a file managing app or connect your device directly to your PC to access the backup files and move them.
Note:
- If this folder doesn't exist, please create one.
- You will not be able to restore your chats if you did not select Back up all data from the Back up chat history option.
If you're not sure how to create folders or move files, please contact your device manufacturer.
• Your device doesn't have sufficient memory or your system specs are too low
The app may freeze or crash if your device doesn't have enough memory or the specs are too low. Please delete any unnecessary data and restart your device before trying again.
