Android RIL driver for Android 14 Issue

I am using EC25 Module with IMX8MP Android 14 OS.

I have enabled Radio 1.4 with Quectel Driver Version “Quectel_Android_RIL_Driver_V3.6.24_master_Release” and after board boots i am replacing libril.so with quectel provieded file.

When vendor.ril-daemon tries to start it throws error
“rilc_confi_thread_pool” symbol cannot be found.

I have also tried with Radio V1.0 but Android is Showing No Sim in Mobile Networks Setting So I switched to Radio 1.4.

I have followed Steps provided at https://forums.quectel.com/t/ril-library-not-provided-by-quectel/5178/4?u=himanshusibrain and did driver modifications using User Guide in docs folder.

I have tried using Radio 1.6 too but same error occured, Below are logs for that

I found problem for “rilc_confi_thread_pool” and resolved it. I did modifications in default rild serivice code and have added this function there. But now as i am using Radio 1.6 i have to replace libril.so and this functions is missing.

Now Another error occurs,
