自己回自己的文章，后来我写信给kobo客服
【台湾kobo回应】
由于台湾未贩售电子阅读器，关于您来信的问题，我们未能与予协助，敬请见谅。
建议您可联系购入阅读器或有贩售阅读器国家的客服人员寻求协助
【日本kobo回应】(写英文+Google日文翻译，收到全英文回复，而且速度很快，大赞!)
简单说，就是还原成原厂设定，如果真的不行要回日本送修，
然后我的问题，回复原厂设定后，已经解决了，松口气，附上客服回复内容
Dear Customer,

else who currently lives in Japan.
First, please take a look and try the following steps that may solve the
