I am a step below Noob if that exists.
Thanks to XDA, I was able to root my LG Optimus L5 E612 on JB, V20d: install CWM, and install AOSP 4.4 on Windows 8.1 PC without any problems.
Here is what I did:
I pulled out the LAN cable.
Turned off Antivirus and Windows Defender.
Edited "hosts.ics" file using the instructions given here: http://forum.xda-developers.com/show....php?t=2409308
In my PC it was "hosts.ICS" file with MS Outlook as the default program.It was the only step I followed from the above guide. Earlier, I had tried to root the phone using that guide on Windows 8.1 as well as Windows 7 without success. Probably antivirus and/or Windows defender spoiled the efforts. I just don't know what went wrong then!
Then the fun started: My phone won't allow me to do anything! It kept on displaying the error message
"android.process.acore has stopped"
But then I followed this guide:
Now my phone is working just fine as far as I can tell. Wifi is working. Not tested Bluetooth as yet.
Thank you people!
