For those of you who tried to install regular CWM recovery for AT&T or Verizon S4 with locked bootloader, you may end up in a nasty bootloop.
To fix, you just simply need to flash stock recovery back with ODIN.
Download the tar file and flash with ODIN, your phone should be booting now.
Also, you can install stock recovery on any stock firmware that you’ve rooted with CWM or TWRP recovery so you can take OTA.
