I flashed this kernel but it seems that there is a problem with my memory card it says ERROR: 1 Error installing zip file 'external_sd/rainbow_a12_3.0.zip' I just flashed the zip using twrp did I make any mistake?

-small synchronization improvement
-various debugs have been disabled
-XOR accelerator module of the ARM NEON has been updated
-added optimized atomic bitops
-added hwtracing driver that improves power management for GKI
-exchange has been increased from 60 to 100
-memory optimizations
-optimization in the only slub branch
-CFI has been enabled for increased kernel security
-ashmem has been rewritten for higher performance
-some kernel latencies have been reduced

Sir do i have to be on a stock rom with out root to successfully flash this kernel? Coz i have magisk patched AP then i tried flashing this thru TWRP after clearing cache but the result is endless reboot..

What steps are needed to install this kernel from twrp as it bootlegs my device running on u2 firmware. Rooted with magisk. Install is OK but boots then asks for sim pincode. Then it starts reboot over and over again.

when you unlock the device does it restart automatically?
Does the SSRM warning appear?

    Indeed. Found it to work now. Compiling with clang higher then 11 will result in failure though. On clang 11 all ok
    can i make a correction for you

    Vou tentar consertar

    Não funciona. Depois de piscar em uma rom de estoque enraizada de android 11, acaba em um tijolo macio.
    Eu fiz uma nova compilação
