uname -r
6.1.21-v8+

I have followed all the usual steps to install the firmware. All other version for RPi work perfectly fine, but on pi4 somehow it reverts back to 7.45.241. No errors given whatsoever. Maybe you have a clue what's going on?

PS: The blob error is my doing, I deleted it to see if it would make a difference. It did not..

It does work on a fresh install somehow, but when I try installing it with my ansible build the pi 4 drivers will not load/install. The others I am installing with the ansible work perfectly fine.

But installing them afterwards doesn't work either.

sudo nano /usr/lib/modules/6.1.21-v8+/kernel/drivers/net/wireless/broadcom/brcm80211/brcmfmac/brcmfmac.ko

When I search while nano-ing this file for nexmon it finds multiple 'nexmon' in the file, but still it does not load version 7.45.206.
