Unlock Boot Loader of E791? - LG Optimus G (International)

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] I cant get into fastboot for recovery after unlocking bootloader

hey guys i'm having an issue going into recovery mode, via fast booth after i unlock the boot loader.
i made a youtube video of what happens from start to finish. basicley, after i unlock the boot loader i can no longer get into my android os, or fast boot, or recovery. my phone is 'soft bricked' and the only way to come back from this is to go into download mode and reflash z7 image.
ive tried using rom manager to get into recovery after unlocking the boot loader but it still does the same thing after restart, a quick flash of the LG logo and a black screen that doesnt seem to every go away.
if you have 8-10 minutes can you please watch my video, i go thru step by step what i do to downgrade to z7 to unlocking boot loader.

I just unlocked my phone this morning with no problem. I think your problem is your unlocking with your computer and then running the unlock app on your phone. Try unlocking with just the app.

so you rooted, then ran freegee?
which recovery are you using?
That's all I did. I've been rooted for a while, yesterday I got the freegee app from the play store ran it and picked twrp for my recovery.
My phone is now unlocked running stock rooted v9. Have you went to irc for help?

Did you do OTA v9? There are rooting problems with that. The devs have suggested you root stock v8 and then flash the v9 rooted image from the forums.
Yeah sorry I should of specificed that I flashed the deodexed stock rom from the forums.

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.

turn on you phone, if the firet screen is ''google'',it shows you phone is unlocked

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 .

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

Freegee won't unlock bootloader!

Hey everyone, I had to reflash the ZVC software through LGNPST because I bricked my phone and now I'm having trouble unlocking the bootloader - I've never had a problem with this before! When I run Freegee it doesn't even ask or have the option to unlocked the bootloader, just to flash recoveries. I tried that hoping it would unlock it, but it didn't work. The older versions you would just click "unlock my phone" but this new one it doesn't exist. I even tried using an older freegee to unlock it, but even though it says "Your phone has been liberated!" it still remains locked. Any ideas?

Have you tried the sbl unlock in the FreeGee menu? Or teeny bins, since you already have LGNPST.

There is no option for that in the new version of freegee that I downloaded, none that I can find! And yes, I tried the teeny bins as well
The only way to install a recovery is to unlock the phone .

So as Shel said... If you have a recovery, then your unlocked.
I ran it last night and it is even more simple now. Backup EFS, install recovery, Done.

Thanks for the new FreeGee. It's so simple, a caveman can do it.
Guess I need to rewrite/shorten the guide now.
So now we just go straight to the SBL unlock I guess?

If thats the case how come every time i reboot my phone or turn it on this screen comes up saying "Google" with a locked symbol at the bottom?

The Google comes from the sbl unlock that used to be the only option on the new FreeGee.
The Freegee released last night gives you an option of the old style with LG, and the new style with Google.
Eventually you'll end up with the Google style just because that will be needed to unlock your phone. That's just the nature of our phone.
As for the lock symbol, are you sure it isn't an open lock and just not turned? Mine has it and is unlocked. If you press and hold the power+vol up that should give you TWRP or CWM. Whichever was your choice.

[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.
