LINE messenger users may concern how to backup Naver LINE chat history as can restore back once their delete data accidentally. Although Naver LINE app for Android and iPhone build in backup chat history but it’s don’t have recovery or restore feature like WhatsApp messenger which can restore back chat history automatically.
I use Titanium Backup android app backup LINE chat history on my HTC One V android phone unfortunately chat history all gone after restore stock ROM with RUU software as LINE app request to login again, then i decide to learn how to back up and restore LINE chat history manually.
LINE is using sqlite as database. iPhone users easy to backup chat history by using iFunbox application locate User applications/LINE/Documents, backup all the content inside (skins, queue and talk.sqlite files) to computer then restore back to same location path manually.
Backup And Restore Naver LINE Chat History
However android phone need rooted have to go through a slightly more complicated process backup chat history manually. First use root explorer app locate data/data/jp.naver.line.android/databases/naver_line, copy and paste naver_line to PC, then rename naver_line to naver_line_old which backup with chat history.
Assume that now install new android LINE app, login with your account then stop it running in background, locate same path data/data/jp.naver.line.android/databases/naver_line, backup naver_line to PC and rename naver_line to naver_line_new which without call history.
Install SQLite Manager add-on on Firefox web browser and open up SQLite Manager, click on 「connect Database」 button and locate to naver_line_old file.
Click on 「chat_history」 at left sidebar and will display out all the LINE chat history.
Right click on 「chat_history」 option and select 「export table」> put a check on 「First row contains column names」 > click 「OK」 to export chat_history.csv file.
Now use SQLite Manager open up naver_line_new file by click on 「chat_history」 > click 「import」 button to import chat_history.csv file > put a check on 「First row contains column names」 > click 「OK」 to import chat_history.csv file.
Rename naver_line_new to naver_line and put it back to data/data/jp.naver.line.android/databases/naver_line on android phone, all the chat history already restore to android phone, that all.
Now reboot the phone and connect LINE to internet, if you can’t notice chat history appeared then try sending a chat message to your friend, all the chat history will appear.
PS: Today LINE for android rolled out an update that can import your backed up chat History including messages and photos now (1/2/2013)
You may try below trick for Android if felt above backup method difficult for you to follow.
Thanks TechGravy . This article definitely got me on the road to restoring my prior chat history, which I am thankful for. LINE simply is pretty poor at restoring history when uninstalling and installing compared to Whatsapp for example.
Ultimately the above step by step didn’t fully work, as I still wasn’t able to see the chats within LINE. The article also doesn’t discuss how/if to rename the table back to chat_history, nor if/that you should also export the chat, chat_member, and chat_notification tables. Either way, it’s a fairly involved amount of work.
However, I was able to get restoration of a prior install’s chat history to work!
Take the fresh install’s version of the ‘setting’ table within the naver_line DB file, export it to .csv, then import it into the older instance of the naver_line DB file. Basically, this will re-entitle you to use your old naver_line db within the newer install. To finish, use root explorer to move your doctored naver_line db file into the directory that the author describes.
If you simply try to use root explorer or titanium backup to restore the older naver_line db file, LINE doesn’t allow it, and the app will automatically delete all your history. Ridiculous, but that’s what it does.
Seem LINE latest update already fixed some loophole since i use the method that mentioned in the post can be backup the chat history.
Latest LINE for android rolled out an update that can import your backed up chat History but after tried, we need to backup chat history one by one of your friend and can’t one time backup all the friends chat history, hope LINE can amended it.
Thanks again! I would have had no idea on how to locate or read my old chats without your article!
Your method doesn’t work anymore. Line will automatically deleted all history. Stephen’s method doesn’t work anymore too. “Sytem error. An error has occured. Please try again later”. Do you have other method. I didn’t backup my chat so I can’t use import it.
