自己回自己的文章，後來我寫信給kobo客服
【台灣kobo回應】
由於台灣未販售電子閱讀器，關於您來信的問題，我們未能與予協助，敬請見諒。
建議您可聯繫購入閱讀器或有販售閱讀器國家的客服人員尋求協助
【日本kobo回應】(寫英文+Google日文翻譯，收到全英文回覆，而且速度很快，大讚!)
簡單說，就是還原成原廠設定，如果真的不行要回日本送修，
然後我的問題，回復原廠設定後，已經解決了，鬆口氣，附上客服回覆內容
Dear Customer,
This is Kobo Customer Care.
We apologize for any inconvenience may have caused.
First of all, we do not offer any repair service for eReaders.
Also, we do not offer replacements for other countries, and we only can
replace your device when you have a chance to live in Japan or have someone
living in Japan to help you.
If you live in another country and if your Aura ONE is replaceable according
to our Warranty Rule, we would like to offer your replacement with someone
else who currently lives in Japan.
First, please take a look and try the following steps that may solve the
problem of your Kobo Aura ONE.
Please try them again even though you have already done before.
