[KERNEL][KARATE][OREO][Final][v9.0] RaidenKernel [15-05-2019]

Search This thread


I have a Lenovo K6 Power (k33a42) on RR OS Oreo with the October security patch... So the problem I didn't read this thread completely to know that this was only for lineageOS... So I flashed r8 of the kernel through twrp and now it doesn't reboot to system... Whatever I do it keeps rebooting to the bootloader. Can someone help me out with this? @arunassain is there any way to fix this?
P.s. I'd love to hear if there's a way to fix this without losing any data or anything..
Thanks in advance!
Just flash the rom zip again without wiping anything. That should work.

K6 power stuck in fastboot mode

Hi all..

I flashed Radien kernel build feb 2019 via TWRP, in my lenovo k6 power. But after flashing, my phone always boots in the fastboot mode and not regular system boot.

I fixed it via restoring from the backup. But what can I do to flash this latest build of kernel.

Please help..

Do not ask same question again
If you do not read OP or ask same question again then you'll be ignored.

Happy Flashing!

    Raiden Kernel

    I am not responsible for bricked devices, dead SD cards, thermonuclear war, 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, and if you point the finger at me for messing up your device, I will laugh at you.
    Please read completely this thread before using. If you coming from other custom kernel, please restore to stock boot.img or dirty flash your rom before flash this!
