Download the MDA89D Factory Image Open it (I used 7Zip) and extract radio-angler-angler-01.29.img Copy this to the platform-tools directory on your computer and rename to radio-old.img (If you're unsure of how to do this, you probably shouldn't be fooling around with this stuff anyway. But if you want to, look up unlocking your Nexus 6P and that should steer you on the right path) Power down and reboot into fastboot (Power + Volume Up + Volume Down) Connect your phone to your PC Run the command "fastboot flash radio radio-old.img" Reboot

Has anyone else seen that? Looks like 5X owners were able to get Band 12 working on T-Mobile proper by flashing the radio from a previous version. Thoughts for us 6P owners?NOTE: I got Band 12 working on the 6P! YOU MUST HAVE THE BOOTLOADER UNLOCKED OR UNLOCK IT PRIOR TO DOING THIS! Also, I am not liable for anything by you following these instructions. Just trying to help others out.Instructions are as follows:Not too difficult. This should just work without any problems, but - again - you are doing this at your own risk.EDIT:I just downloaded the MDA89D factory image and flashed the radio by itself. Will report back shortly.EDIT2:The device booted fine with the old radio image and the newest firmware, so we're good there. Waiting on the device restore as I had to wipe (since I was dumb when I got the device). Will report back once I get LTE Discovery installed.EDIT3:After a quick test with LTE Discovery, it looks like that worked in enabling Band 12! I ran downstairs where I could only get HSPA+ before and Band 12 with our Note 5 / G4 currently. Here's a shot of LTE Discovery:
