How to unlock boot loader LG E 975

Hello
This is my first post on xda forums. I just purchased LG optimus G E975 ( indian version ) yesterday
I have used this guide
http://forum.xda-developers.com/showthread.php?t=2163814
to root my phone and I there is no error in rooting and I can find the superuser app installed.
I have a simple doubt by using the above guide is my bootloader still locked or it's unlocked in the process ??
I also want to keep my stock android and don't want to use Custom ROM as of now ( I would like to explore features that LG provided )
I just want to unlock my bootloader and have full root access and want to install custom ROM clockworkmod.
Thank you

CWM is not available for E975.

Succes ? I'll get my e975 in a few days. And of course want to unlock BL, root and if there are some, to flash custom kernel.

FreeGee not working on E975(yet).I have E975 10c(4.1.2)(Orange romania) and i also want cwm on it.Rooting procedure is very easy,took me about 1 minute(thanks fiddy for that).
Unfortunately i couldn't find anything related to cwm.
Also, is there way to check bootloader status?
Thanks.

CWM is not available and will not be.
unlock is working with another version of freegee.
but is not public and Shelnutt2 is working on an easier way, but he need some files.
please try the latest freegee beta: http://downloads.codefi.re/shelnutt2/optimusg/freegee/FreeGee-beta.apk
starts the unlock method and upload the files for freegee to support your rom in the future.
thanks

Just an update, as soon as some from HK or tw can send me the ICS sbl stack we can move forward with a better unlock. If no one offers up to dump the images soon I might have to ask someone on an e975 to kdz to their ICS firmware and grab them for me.

Are you rooted? What happens when you unlock? Does it just reboot to a black screen?

How do I find out if rooted LG e970 has recovery system and if bootloader is unlocked

Hello to everyone,first time here and new to this root thing.
That said,I just purchased a LG E970. The phone came unlocked and rooted but don't know if it has recovery system or if bootloader is unlocked. How do I find out?
Sent from my LG-E970 using xda app-developers app

Enter in recovery mode and see if you have custom recovery. On optimus G you can't have CWM recovery without unlocked bootloader.

Solution
Install this application that can automatically boot in recovery mode (if there is recovery installed)
QuickBoot -> https://play.google.com/store/apps/details?id=com.siriusapplications.quickboot
If there is no recovery installed you have to install FreeGee and unlock your bootloader and install a custom recovery with it.
FreeGee -> https://play.google.com/store/apps/details?id=edu.shell.freegee_free
Anyways, even if your bootloader is unlocked and a custom recovery is installed, I strongly suggest you re-unlock and update your recovery to the last version of CWM with the help of FreeGee.

what??you lost me there. Could you ellaborate please?
The easiest way to see if you are both rooted and unlocked is to enter in recovery mode.If you have recovery mode, it also means you are rooted.You can't unlock the bootloader if you are not rooted, so checking for root is redundant .

Sent from my LG Optimus G , the best phone for me。

Is there any guides to relocking Optimus G specifically? I got the phone already unlocked but I can't return it to stock since KDZ updater and LG Mobile Support Tool can't detect my phone.

hi all.
Once I unlocked and installed CWM recovery to my current stock rom, can I still use KDZ updater to flash KDZ file in future?

Won't reboot into Recovery Mode

Hey everyone,
I've tried ROM Manager, Titanium Backup, Quickboot, even the manual ADB way, and my LG Optimus G E971 (Canada w/ Rogers) won't boot into recovery mode. So I can't backup and/or install ClockWorldMod and install ROMs
Upon reboot, this is what I get. Please see the below image. BTW: I can get out of this by holding down the power button and power the phone up as normal, but can't boot into recovery mode.

Bootloader should be unlocked before installing cwm

Yes bootloader unlocked first because it needs loki patched for recovery and kernel

Unlock Boot Loader of E791?

It seems unlocking the boot loader is proving to be very difficult for me I tried freegee and almost bricked my phone.
Any recommendations would be appreciated.

When I tried the freegee for mine it seemed to work, but when the phone restarted is got stuck at the logo. I had to use the LG recovery tool to bring the phone back.
What procedure and FreeGee did you use? Am I correctly in these steps, Root the phone first, then Unlock boot loader, install ClockWorkMod, Install ROM, & GAPPS

[Q] Issue using FreeGee to flash recovery on e980

I have a brand new LG Optimus G Pro e980 with the software version E98020G.
FreeGee says it cannot use loki on it so the CWM recovery won't work and when I tried to put TWRP on it, it just sat there doing nothing.
What am I doing wrong?

OTA update just bricked me
I was rooted and an OTA update just bricked me.
Says
Secure booting Error!
Cause: boot certification verify
I can't get the phone in download mode or anything...did I just brick it for good?

Nevermind, I am an idiot.
