Stuft is quiet easy. You just need to have an rooted phone, and an root file explorer ( e.g. ES file manager). You need to navigate to /data/data/ and then if you use normal Opera navigate to /com.opera.browser; if you use Opera beta: /com.opera.browser.beta; if you use Opera mini: /com.opera.browser.mini . Now you're in the Operas data folder. Just need to open the folder /app_opera. It shall contain an file called 'bookmarks' and one called 'bookmarks.bak' (they're written in XML). If you still use opera copy them (to your sd-card), and if you have re/installed Opera, overwrite the other bookmarks files, with them from your sd-card.
If you gonna use an different browser open the 'bookmarks.bak' file, with anny text editor. And search in the XML-code for the right entry. An bookmark look like this:
"children": [ {
"date_added": "123datecode456",
"id": "IdOfBookmark",
"name": "NameOfBookmark",
"type": "url",
"url": "http://www.adressOfBookmark.html"
} ],
Just look for the right name and copy the address.
I hope you'll bee able to follow my tutorial. 🙂
