yes, I patched the full AP with the special magisk version. I followed the steps at this post at first, and then I found the tg channel for Exynos 850 devices so I'm following guides there1. Did you root using the full ap file patched with the special a217 magisk? (This contains the patched boot.img and vbmeta.img)
You can't downgrade firmware
Sorry I mean downgrade the baseband version, I flashed the A127FXXU4AUK1 that I saw it is widley used for this device, but I have the same problem, not able to mount /system folder.
In recovery mode with MTP seems that I can mount system, but when I restart the device I cannot interact with that folder, also mounting /system from a terminal with root access (recovery or termux) result in fail, with the same error pasted here
I also tried to install the TWRP and OFox recovery following the guides on tg, with no luck.
Only the OFox one is working for me, I tried also the others recovery but they are causing boot loop
My a127f/DSN comes with baseband A127FXXS4AVB2 (ITV) [security update 02/2022] from factory, I'm afraid this is the reason why I cannot access to the system folder.
In any case, thank you very much for your support
