Post [Q] Xperia S (6.2.1.B.96) Problem installing CWM Recovery

On UB, rooted. Was previously running on PureSlim rom. Now on other rom based on stock kernel 6.2.1.B.96. I had TWRP before. But after flashing the new rom, then the kernel, i could not boot into recovery. So i tried to install CWM. Tried via RecoverX(says installed sucsessfully,but was not able to boot in phone), cwm-install-en.bat file(says" an error occurred executing abd.stoping process) All the drivers are properly installed! Searched for kernels with pre-rooted and installed recovery, but the threads were closed.All i need is a Recovery.
Someone please do help me with this :/
Thanks in advance!
