Sorry if i wouldn't be of help but, i believe that it doesn't worth too much to retrieve those value while those PIC are really cheap, just throw it away and use another one. The next time just read the value in, then write it down on a paper or use liquidpaper underneath your PIC and write value there.

BUT Melanie already post something on that
