Same here. Internal firmware 1.06 runs X1Plus 2.0 with Bambu 1.08.00.00 base firmware from the SDcard, in LAN mode with MAC address blocked at the router. With OrcaSlicer, this does everything I need. I never wanted an AMS, don’t print from MakerWorld, don’t use Bambu filament, do not need Handy or the Bambu cloud. Recent firmware upgrades have no advantages for me and posts here on the forum suggest they were released without proper testing. Life is too short to be an unpaid beta tester.
I doubt I will allow any further “upgrades” unless/until X1Plus 3.0 comes out using a newer Bambu base firmware. Then, if I do not like it, I can revert by simply swapping SDcards.
