I have looked far and wide and haven’t found a firmware update for 3.05 for the Framework 16. I have seen a beta firmware update for 3.04 for the Framework 16 from July, but it was still in beta due to issues that were found. There is a 3.05 stable firmware for the AMD Framework 13 that was linked above, but it explicitly says:
Please note that this software is for Framework Laptop 13 (AMD Ryzen™ 7040 Series) ONLY!
For other Framework Laptops, please read the article located HERE.
The forum thread for the beta 3.04 firmware for the Framework hasn’t had any official Framework posts since July 31, except for @Destroya, on August 22, linking to a previous post, acknowledging that Framework was aware of (and tracking) the issues plaguing the update.
