    Latest build works great on CRdroid unofficial 12.1, EvoX, AICP 17.1, LineageOS 19.1 official, CalyxOS. All on fajita. Release prior worked great as well. There was one release that had an issue and it was quickly pulled and resolved. The way I recommend flashing is through Franco Kernel manager. First back up your stock boot image from the kernel manager app, then flash. This way you can monitor the flash results and if something goes wrong, which if it does is likely due to some sort of modification you've done to the device already and not due to the kernel itself, you have your stock boot image backed up so you can just reflash it through TWRP or fastboot.

    * I am not responsible for bricked devices, dead SD cards, or you getting
    * fired because the alarm app failed. Please do some research if you have any
    * concerns about features included in this KERNEL before flashing it. YOU are
    * choosing to make these modifications.

    I would like to share with you my personal kernel build. It's based on official OnePlus kernel sources combined with some additional features and commits from different great developers out there.
