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

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?

Do I need to update bootloader on a stock phone?

I'm gonna root and install a custom ROM on my friend's phone and I'm just wondering if I need to update the bootloader before installing any ROMs?
So should I root, then flash the bootloader update via Odin before installing a ROM?
Or can anyone give me a good process for doing that, it would really help

What version bootloader do you have now and version do you think you need?
I simply did a search on "bootloader" and found this relevant thread for you. Take a look a post #2.
Hope it helps.

I meant like my friend's phones are purely stock.. And I'm on a custom ROM. About a month ago we all got bootloader updates in order to use new ROMs so I'm wondering if that's what I need to do for my friends too, before flashing them a rom

I'm sure that it depends on what version bootloader is currently installed, and what version your ROM of choice requires. The fact that their phone is now "Stock" doesn't tell you anything. I am running a nightly version (7/7/13) of Rootbox (Doesn't get any newer than that) on a one year old S3, and have never updated my "Stock" bootloader because it was not necessary for what I need - and there isn't one newer.
Every time you flash, you are taking the chance of something screwing up. The only thing worse than bricking your phone would be bricking someone else's. IMO, you need to do some more research to answer your own question. The devil is in the details.
Good Luck.

If he is on the most current stock update provided by the carrier then the bootloader should already be updated.

[POLL]Install CWM from ICS without unbricking.

I wanted to find out if anyone thinks it would be useful to be able to root ICS and install CWM without having to downgrade to GINGERBREAD first? I have pulled the unlocked bootloader from the P936's v10i Rom and replaced the locked bootloader from ICS and install CWM Touch and therefore eliminating the need to unbrick your phone first. This includes either full stock or after a fresh install from v18f/v20x. This is done through ADB using a simple bat file.
So I just need to know:
1. Yes I think this is useful or
2. No this isn't useful.

1. Absolutely. I am on ICS and installing a recovery seems a pain in the ... Of course every easier method would be highly welcome.

You cannot unlock the bootloader on ICS and you need an unlocked bootloader in order to install a custom recovery from what I have seen and read.
I saw in another post that someone was able to do and I would love to see a bat file that saves us the trouble of unbricking.

I found a way . Actually it more accurate to say that I found a way to push an unlocked boot loader that bypasses the lock. Fully tested. I will provide more details when I get the thread done. No unbricking needed.

Awesome. Do you know if this would work on a P935 as well or did you just try it on a P930?

You have to unroot. Then install the update via ota. Then re root.

It doesn't matter. The easiest way is to connect it to your pc via LG Support Tool which will update your phone regardless of your root/unlocked status.

No, I'm just wasting my time giving bogus assistance to people.
Of course I am sure it works. I've done it before as many other users in the past.
If you already have the latest kdz file, you can do it in a quicker way by using the flashtool but it sounds like you're new to all this.
You can unroot & update via OTA or use the support tool which will download the updated firmware and install it for you regardless of your root/unlocked status as I've mentioned before (select Update Recovery).
You won't lose any data or settings. It's like dirty flashing a custom rom.

If you're unsure about using the support tool, why don't you just unroot and update via OTA? Like I said above, if you decide to use the support tool, select "update recovery" (your phone should be connected as LG software usb mode). It will put your phone into a download mode, download the latest firmware (1.6gb), and proceed with the installation. If you choose the OTA method, the download size is much smaller.

Ok im now confused. When i want to install it via ota update i have just to unroot the phone, because i read that if you have an unlocked bootloader it will stick in a bootloop? So i have to go in supersu and click full unroot and install the update and re-root and the unlocked booltloader doesn't matter??
And via support tool: i have to connect the phone to the computer and download the full firmware and i don't lose the data, is it right? Sorry for this stupid questions but i have no idea.

In your case, since you have unlocked bootloader, you have to use the support tool. If you have only rooted the phone, you can use the OTA after unroot.

Stock Rooted rom?

hi, I just recently aquired the Nexus 7 2013 model, and I am currently not rooted. I want to root but I dont want to run CM or all the other custom roms. I just want a stock rooted rom.
Is there a stock rooted 4.4.2 rom for this device?
That is all, thanks!

There is one here: http://forum.xda-developers.com/showthread.php?t=2563017
You will need a custom recovery in order to flash it!
Or you can just flash the SuperSU zip in recovery and it'll be rooted

I'm curious. I've never used a device with a locked bootloader. Since this tablet is about to get the 4.4.3 update, will unlocking the bootloader affect the update? Will I still receive the update.
I'm planning on unlocking the bootloader but not flashing the rootzip yet until I get the update.

Yes, you will still receive the OTA. Having an unlocked bootloader has no effect on updating via OTA.

You could just root and then re-lock the bootloader

Only recovery needs to be stock to relock the bootloader, you can unlock, root and then relock - then you have rooted stock ROM and a locked bootloader without having to flash a custom recovery or ROM.

Are you sure? This wasn't the case with my Motorola Xoom. I thought everything needs to be stock, wouldn't this defeat the point of relocking since its meant to be factory settings for warranty purposes?

fair enough, I stand corrected! Didn't know you could re-lock a rooted device.
So could you flash OmniROM, flash stock recovery and re-lock?
