Stuck with custom recovery
Just recently rooted my LG E970 (AT&T) so I'm fairly new to this.
I had been running CM11 for about a week and a decided to update to the newest nightly version earlier (cm-11-20131228-NIGHTLY-e970.zip). Well, the installation of the ZIP file failed (Error executing updater binary in zip). I'm using TWRP 220.127.116.11 recovery. Now my Optimus G only boots to TWRP recovery.
I've read that TWRP are having some issues installing 4.4 custom ROMS so it's recommended to use ClockworkMod. The problem is I don't know how to install ClockworkMod manually or using a PC.
So, how do I install CWM and override TWRP without an actual OS on my phone running?
