Thank you for helping these folks out. I truly appreciate it. I hate that I'm always a little late with these. Life just...keeps happening. Anyway, 8.1 is uploaded. As always, I don't have a 5X anymore so I have no way of testing, but all should be well.

Compilation number on my nexus 5x is opm3.171019.014. (security pack 05 Feb 2018) Can I use boot.imgs from first page corresponding to previous build (OPM3.171019.013)?

Hello!
Do I understand correctly that I can lock the bootloader after flashing this kernel, and there will be no problems with Google Pay?

    *8.1 Official is here! -Updated 1/7/18*

    Thank you to @osm0sis for the Android Image Kitchen tool used to modify the boot.img's, found here. An especially huge thanks to @Tigerstown for teaching my Windows-using rookie ass, and just for supporting a device he doesn't even own for so long. It is incredibly appreciated.

    Next to each build number you'll find the first links are simply boot.imgs modified to just disable forced encryption. The second links are stock boot.imgs that have both disabled forced encryption, and dm verity has been disabled as well - take your pick. Only SYSTEMLESS ROOT is working with these boot.imgs. Tigerstown has put a lot of effort into trying to get system root working, but unfortunately it doesn't seem doable yet.

    Naturally, the regular warnings and disclaimers apply here. I cannot be held responsible if anything goes wrong, no warranties, etc. Of course should something happen, myself and the community are here to help.

    Going from using a boot.img that is just decrypted to one that also has dm-verity disabled will cause SuperSU to fail when flashing - specifically when the script gets to patching sepolicy.

    Starting with NRD90R and on, see the download links in this thread below. Any build prior you will find the modified boot.imgs for your respective builds in Tigerstowns thread here.

    Simply flash the corresponding boot.img for your build number via fastboot:
    Code: 
    fastboot flash boot boot.img

    If your device is currently encrypted and you are looking to decrypt it, use the commands below. Please note that coming from an encrypted device, when you decrpyt it you WILL WIPE YOUR PHONE AND YOU LOSE YOUR DATA.
    Code: 
    fastboot flash boot boot.img
fastboot format userdata
fastboot format cache

    How do you disable dm-verity in the boot.img just out of interest?
    Click to expand...
    Click to collapse

    Once the boot.img file has been extracted (like with the Android Image Kitchen I have linked in the OP), It's simply editing 2 lines. Within the ramdisk folder resides the fstab.bullhead file (file system table). Lines 6 & 7 are edited so that everything after the word "wait," in both lines is deleted. It's super simple, and I can't take any credit for any of this. @Tigerstown showed me what to do, I simply just do it for any new firmware to make it easy for people who want stock kernels and want to keep decrypted and/or dm-verity disabled. See below-
    From this:
    Code: 
    /dev/block/platform/soc.0/f9824900.sdhci/by-name/system       /system         ext4    ro,barrier=1,inode_readahead_blks=8                             [B]wait,verify=/dev/block/platform/soc.0/f9824900.sdhci/by-name/metadata[/B]
/dev/block/platform/soc.0/f9824900.sdhci/by-name/vendor       /vendor         ext4    ro,barrier=1,inode_readahead_blks=8                             [B]wait,verify=/dev/block/platform/soc.0/f9824900.sdhci/by-name/metadata[/B]
    To this:
    Code: 
    /dev/block/platform/soc.0/f9824900.sdhci/by-name/system       /system         ext4    ro,barrier=1,inode_readahead_blks=8                             [B]wait,[/B]
/dev/block/platform/soc.0/f9824900.sdhci/by-name/vendor       /vendor         ext4    ro,barrier=1,inode_readahead_blks=8                             [B]wait,[/B]
