There's other ways to flash roms/kernels.
Well, somehow I can not fully grasp the issue of uploading OC kernels by software.
I only have the CleanSlate kernel installed.
[KERNEL] CleanSlate R 2.6.3 |KCal|Dimmer|AdBlock|SafetyNet|FlashLight|Dtap [31Jan] | XDA Developers Forums (xda-developers.com)
And I wanted to try it too (Adreno clock OC):
[KERNEL][GPU OC] SmurfKernel 1.1.0 [OOS 10/CUSTOM UNIFIED] | XDA Developers Forums (xda-developers.com)
Although I have Magisk (21.4) as if to upload.
I also have Franco Kernel and EX Manager pre-loaded.
Somehow, instruction to upload the kernel through: Magisk 21.4 (except for the uploaded CleanSlate) / EX / or Franco is not readable enough for me to take it or I just can't understand it.
