求救~~LINE備份匯入求神人解答~~

因為我朋友的line突然跳出錯誤,救直接登出,ROOT後進到data/data/jp.naver.line.android裡的databases看到naver_line已經是空的,但是卻有出現一個naver_line.back,這個檔案我打開來看理面的chat_history,都有之前的對話,所以我從這個把它匯出CSV,但是在新的naver_line,匯入會出現錯誤訊息,

以下為出現的錯誤訊息



SQLiteManager: INSERT INTO "main"."chat_history" VALUES ('277363',"700747591760",'1',"u1fd9d5793d74a0292b901b1433cb79d3","u1fd9d5793d74a0292b901b1433cb79d3","都還好耶","1384653193585","0",'1',null,'1',null,null,null,null,null,'0',null,null,null,'0',null,"") [ PRIMARY KEY must be unique ]
