You need another 3110c to do this. Just open that mobile(other 3110c) with oxycube and open the path, c:/hiddenfolder/certificates/ and copy all the contents, and save it somewhere you want. Disconnect that 3110 and connect your 3110 and paste the content at the same path. All your certificates will be recovered. For oxycube, download it from here.

And also, you have posted this topic in wrong section. From next time, better ask these type of questions in technical queries and solutions.
