BTW, for anyone that doesn't know, to get root you can use Magisk Manager to patch boot.img for this ROM, then flash that patched image.
There's a few approaches you can follow to do this. Personally, TinyFastbootScript did not work for me at all. I followed the "Lineage Recovery" steps in the OP. I then downloaded Lineage-images-18-20210723-1344-nio-144.zip, extracted boot.img from it, copied it to my phone, patched that file with Magisk, copied the patched file over to my phone, rebooted into fastboot, and flashed that image:
fastboot flash boot_a boot.img
fastboot flash boot_b boot.img
and now I have root. Clearly you can cut some steps out, but hopefully that will help some people.
Fixed in upcoming version, thanksAccessing the notification light settings causes Settings to crash for me.
I flashed lineage-18.1-20210723-HOMEMADE-nio.zip
Also, does anyone know how to enable a vertical Recent App selection screen? Rather than having the horizontal app previews, which is annoying to navigate, especially when I want to close all my apps and have to swipe all the way to the right to reach "clear all".
You did it wrong, extract TFS and rom to same folderCouldn't flash with tinyfastbootscript. It says "access is denied" then lots of "the system cannot find the file specified" lines.
It only flashed the boot and wiped everything else I think, but didn't flash the ROM.
Had to revert to stock ROM.
Anyone knows why tinyfastboot doesn't work?
