I just posted this in another section, but it's worth posting here. I had a big headache trying to update the ST16. Hope this can save others the frustration.Here it is:
I had a different problem updating the ST16 and it had me stumped for hours. I updated the H, no problem and fast. Then, I followed the video closely with the ST16 and pressed update and then it would start unpacking the file and shortly after just stop updating. After cursing, re-reading the how to update process over and over, I was stumped. Just by chance, I went onto the tablet section and saw a notification in the top left hand corner of the screen saying i was extremely low on internal memory. I had dumped a few videos onto the the internal memory section of the ST16 and there was not enough internal memory left to successfully update the ST16. Once I cleared the files I had stored in the internal memory, it worked like a charm.
