Get all the text messages(SMSs) on my phone as a file on my computer [duplicate]

Question

I have a Nokia Lumia 710 which is running Windows Phone 7.8. I would like to get all the text messages I have on my phone as a text file on my computer.

There seems to be solution for phones running Windows Phone 8 here, How can I export or extract my text messages to a file?

But, most of what I found on the Internet is deeply disheartening. Many claim that this is impossible. Some of the sources I went through are,

Please note that I am running Windows 7.8 and NOT 7.

One way I could think up is to make a video of the phone's screen scrolling through all the messages and use text detection on the video. Is there any other less time consuming way ?

I am open to doing lots of work for this. I tried to access the storage through a Linux(Ubuntu) machine as well, without much success. I am open to using 3rd party tools as well. If nothing else works, I am also open to methods which can cause damage to my phone.

Thanks !

EDIT

This is not a duplicate of How can I export or extract my text messages to a file? , because this question is specifically for Windows Phone 7.8. Which is considerably different from Windows Phone 8.

According to a few sources on Microsoft Answers, there is currently no app on the marketplace to do this nor 'built in' support for this on Windows Phone 7.8.
