Just tried it and it still didn't work. After applying both parts of the fix, 5G radios are still low powered. 2.4G has proper power output. Also of note, part 2 of the fix deletes cal-ahb0000.bin. This file gets recreated when rebooting.
Edit: Just to add, I am using the NSS build for RAX120 posted here: Qualcommax NSS Build
