Sometimes after an app update, especially if I was just using that app, I have to restart the device. Netflix is the biggest offender for me. Newegg is probably second, and the app that's most likely to crap out and need a reinstall.
Rarely do I find anything not working after an OS update, and it's likely an app needing an update, if so.
Be careful on inserting this (or any G34 chip) into the socket. Once you pull that restraining lever, it is either a good install or a piece of silicon jewelry.
