Hello sir,

I am a user of Samsung Galaxy A15. We don't have a useable custom recovery yet.

We use kernel flasher to flash GKI kernels

recently we hit this error

here is ak3 log

How to fix this ?

[mylove90]

After some investigation i found out the following My device...Samsung Galaxy A15 is non-a/b device with dynamic partitions layout.

is there anyway or fix to make that usable on such device ?

Thanks in advance Best Regards

That error is coming from AK3 here, so that issue will need to be resolved upstream.
