Hello everybody!
I am from Argentina, sorry for my bad english!
I have a Nexus 4. The phone had never a modification...
I want get root access in the phone, i understand that i have to unlock the bootloader but...
if i install CM (following the easy steps of the website get.cm), this process may unlock the bootloader automatically? And could give me root access?

And another question:
if i install CM (following the easy steps of the website get.cm)...
Can i then flash the phone with "franco.kernel" to get USB OTG?

Thanks and very sorry for my bad english!

You need to unlock the bootloader in order to flash a custom rom. But it's easy! Here is a guide (including how to root):

About Franco Kernel... Franco's is AOSP based, CM is CAF. It may work, but with wrong colours (or it may cause bootloops). Look for a CM/CAF basedkernel with usb-otg support in the Development forum, or take a look at this thread:

Hello meatboy371, thanks for your answer...
So, does the installation program of CM does not unlock the bootloader? I have to do it manually?
Look this (is a website):
wiki.cyanogenmod.org/w/CyanogenMod_Installer

Do I need to root my phone before installing?
No. You can have a rooted phone, or not. The installer doesn't care. However, to be in a supported configuration, you need to be running a stock ROM.
Do I need to unlock my bootloader first?
No, you don't. If your bootloader is locked, we'll unlock it for you.

So, can i install CM in my phone without any modifications?
And then, will the bootloader unlock automatically?

Thanks and sorry for my english!

The installer from Cyanogen WILL unlock your bootloader and root your N4 automatically, you don't need any third party app or doing it manually, I did it on my N4 when i got it and everything went fine ;) BUT the process will erase everything on your phone, so be aware of what your doing.

I didn't know that CM installer unlocks the bootloader (i used to flash CM roms from recovery), thanks for the info.

About the kernel, you'll need to find a CM version of Franco's to work with CM roms, like I said before (look at development forum).
About the recovery, I don't know, but if it isn't changed by the CM installer, you can easily flash using fastboot. You can try TWRP, CMW or PhilZ, there are threads for those with step-by-step guides to flash.
