Hello!

Sorry for late answer.

also has a brcm43430 sdio wifi and if so if switching to:

Judging by this error message

> [    7.744262] brcmfmac mmc0:0001:1: Direct firmware load for brcm/brcmfmac43241b4-sdio.txt failed with error -2

Lenovo Miix2 8 have brcm43241b4 sdio wifi. 

With brcmfmac43241b4-sdio.txt from NVRAM, as suggested here https://wireless.wiki.kernel.org/en/users/drivers/brcm80211 WiFi connection works for me with upstream Linux 4.12.4, but doesn't work with Linux 4.13rc1 and Linux 4.13rc3.

Few connection attempts with Linux 4.13rc3 looks like this:
