[GUIDE] How to back out of KitKat to Jelly Bean? | Downgrade to JB LG G2 topic

Many of you will have happened to them what to me, upgraded to VDF KitKat and then realized that root could not be and without root cannot modify anything.
You tried to Flash a ROM JB format KDZ and found out that you can't.

Behold the solution!!

Back to Jelly Bean in a LG G2

It is a bit laborious but simple

1.- Will have to follow the tutorial Manual LGFlashtool, here one is Spanish with pictures and everything, here hyelton LG G2 Stock Firmware (Go Back to Stock)
2.- Download the ROM TOT JB for your phone model: http://downloads.codefi.re/autoprime/LG/LG_G2
3.- Turn on the phone in mode Downloader, (Vol+ & USB to PC)
4.- Connect the phone to the USB port and start the downgrade
5.- When finished it will skip this message on the phone:

"Enter the PIN/password to decrypt"

NOTE
There I was wrong, and I didn't know that, but I think that it must be the password for your Gmail account
As I have said, I'm wrong, because I turned off the phone, then I had to activate the keyboard from the status bar, enter Hidden Menu (in my case I have a D802 - 3845#*802#) and do a Factory Reset.

I'm not sure if it will erase everything by typing the correct code, including the SD, but when in doubt and always before flashing I recommend BACKUP, BACKUP, BACKUP...

Now you can already root install modified Recovery and install KK rooted from Recovery

Good lucky
