You mean 2016, as a9lh first public implementations came on January 2016.It should be safe. I updated my A9LH about a month ago from my initial install of it back in March 2015, so I have V1 for a LONG time. Just make sure you're using the proper data_input v4 and SafeA9Installer v 2.6.7. Make sure you delete your old A9LH folder and copy the new one over from the data input. It could simply be that the data got corrupted during the transfer to your SD card. Check it for bad sectors, then copy it over like 3 times to preserve integrity .
