Installed CWM/TWRP but it isn't installed when booting to recovery mode I have an LG G2-D800 running 4.4.2 KitKat and it is rooted using an app called Stump Root. I have been trying to flash a new ROM onto it and every time it boots into recovery, it boots into the android recovery, even though I have flashed it using Clockwork Mod and TWRP Manager. 
Can anyone help with this and suggest good ROMs to flash to it?
Some stock ROM's may replace the custom recovery with the stock recovery. To solve it you should install the custom recovery with fastboot and reboot to recovery and don't reboot to system. That will prevent the stock ROM from replacing the custom recovery.
