I’ve created this flashable zip with the kernel pulled from the firmware v2.5 of the LEM7 to be able to update to it in custom roms like my LineageOS build or on older roms like v2.4 or older (if for some reason you don’t want to update to v2.5).
You can just flash it using TWRP which you can find in the OpenWatch section.
For me, this kernel version fixes the tilt-to-wake functionality on official roms. It won’t work in my LineageOS build as I haven’t found how to enable it yet.
I hope it’s useful for somebody!
