The Korean LG Optimus G is now unlocked!
If you have a K, S or L varient, you are now fully unlocked!
Instructions
Please note: this requires root before you can install this! If you haven't rooted your phone yet, now is the time to do so.
As with all currently supported varients, we offer two methods of unlock. The first is connected to a computer. The second is through an apk. The apk cost ~1USD, and is a donation to us. The pc version of freegee is free and always will be free.
You can download the apk here. Else read below for instructions.
Also, ensure that you have ADB drivers installed. This WILL NOT WORK without them.
Before we begin: please make sure you have USB Debugging turned on, your phone is in "Charge Only" mode or MTP mode, and your phone's screen is on and unlocked.
This will allow you to see the root access prompt if your phone asks for it.
Download the .zip for your varient at the end of this post
Extract it somewhere on your hard drive
Ensure your screen is on and unlocked
Run the "freegee.bat" script, and follow the instructions.
Do not run this as administrator! the install will fail if you do so.
Once the unlock is complete, check to make sure you have a "backups" folder now in the folder where you put FreeGee. If not, DO NOT REBOOT your phone.
Even a failed unlock will still show the 'congratulations you're unlocked!' text, read the output to see if you have errors!
You should not see any "adb.exe not found" errors, or "tar: invalid magic" errors. Those would be errors in the script.
An error which you can ignore is "No space left on device" after it says erasing old recovery and boot. That's just a side effect of how we clear the old images out.

Important Information
To enter bootloader, hold volume UP and power.
Upon entering the bootloader, you will notice that there is no 'menu' to enter fastboot or recovery. Unfortunately, since the stars didn't align properly, we were unable to tell the new bootloader where to load the images that contain the menu from.
In light of that, you'll have to navigate the menu blind. Use the volume keys to change selection, and the power key to select.
The choices are (in order of pressing volume down):
Start - boot the phone normally [already selected]
Restart Bootloader - reboot into the bootloader
Recovery Mode - enter recovery (CWM)
Power Off - powers the phone off
So, to get to Recovery, you would press volume down twice then power.
If you have trouble with this, watch my video below for a demonstration.

FAQ
Can I flash an OTA after installing this?
No. Flashing an OTA could contain a new bootloader, and it would replace the one we have put on your device. If you flash the new OTA, and it replaces the bootloader but not the boot.img, you could be left in a situation where you could not boot the phone due to a security error. Once you're in that position, the only thing you can do is LGNPST back to stock-- and even then, it is possible that an OTA could enable an anti-rollback feature which would disable LGNPST.
Does this mean I can flash custom ROMs now?
Yes. However, the custom ROM must be made for your device. We're working on a decrapified stock ROM, and AOSP ROMs as well. Be patient for those to come.
How can I uninstall this?
We will be releasing a 0.6 verison soon with easy uninstall. In the mean time you can get on irc, and we'll help you, or you can use the apk in the play store.

Hi, just have a quick question about this method and support variants. Why you say Korean version L is that the L0-1E variant? Would be great if so.

Korean variants are F180L / F180K / F180S. L for LG U+ carrier, K for KT carrier, S for SK carrier. L0-1E is a Japanese variant that nobody seems to have a root process for atm.
Shelnutt2 said:
The Korean LG Optimus G is now unlocked!
We need some more testings for the S varient. There seems to be a slight hiccup with the S varient and before we release anything publically we need more testing. Please contact me on irc if you have an S varient.
If you have a K or L varient, you are now fully unlocked!

What carrier are you on? Sprint? If so you need to visit the sprint forums for the unlock.

So, unless you are in Korea, you're in the wrong forum as Shelnutt2 pointed out.

Yes you can use that apk if you've convereted to E975 (this apk is just the same thats on the playstore plus E975 support). It'll give you twrp or cwm, but you should probably update to a newer cwm than what I have packaged. You'll be able to run jellybean with it.

Guys, please assist or I`ll go mad in a minute and smash this crap with a hammer Wife got SGS S3 Mini/GT-i8190N. Don`t know what network it came from, but was not locked and came from UK.
Her phone suddenly turned off today and won`t boot, stuck here:
http://s23.postimg.org/kbtv942uj/sg1.jpg
How on earth I get it back to life? No hacks ever have been done to it. Google reveals huge amount of people having same problems - stuck at boot screen. Is that some kind of hardware issue with this model?
One of the solutions is to do factory reset - but how if I can`t get into the phone? I can get into ODIN mode, connect to ODIN, but I can`t download firmware as I don`t know what network phone came from or even it was sim ree(not locked to any).
KIES just says CONNECTING... and nothing happens.
There is a forum for this phone here actually .....

Was there a box that the phone came in? Usually somewhere on that you can find something that looks like the software version that came on the phone originally. I know the standard S3 has that and I'll go out on a limb to assume that this one has it as well, if you have the box. Outside of that, not sure what else to tell you.
Good luck!

2-You need to enable USB debugging mode (Settings>Developer options) which is deactivated by default. - I cannot access it as I can`t get into my phone.
Those firmwares can go fine with any I8190 - wife`s phone has N at the end of model.
Also - ODIN doesn`t see my phone, even its in Odin mode and Samsung USB drivers installed.
Okay I just looked up your phone and is not from UK it is from Nairobi

Does that change anything? What ROM I need to download then? Can I flash any ROM or it must be original factory ROM only?
How it ended up in UK then? I bought it in UK, brand new, sealed.
Yikes! No ODIN access ... that's not good. Was going to point you here:

Plugged USB cable in another USB port and ODIN can see my phone. Now, just need to know - can I flash any ROM or only one it came from factory with?
I don't see any firmwares for Nairobi and not sure I would flash one in any case, did you happen to check what version of android was on it when u got it? I know on my G III I can flash any I747M firmware and they all load and boot fine my concern us that you get the right radio and if I had to guess I would use I8190NXXAMG1, hope that helps, when u have Odin started on your desktop and plug in your phone in d/l mode it does not show your phone?

No kdz is available. Your best bet to return to stock is a nandroid backup or one of the stock based ROMs timmytim posted in the development section.
Hard Bricked my lg gpad v410 was stuck in a loop couldn't even get recovery. Caused from using the odex att 4.42 then tried updating with twrp recovery still installed. All I could get was the twrp recovery when rebooted. Next tried stock recovery, bad move, stuck in a bootloop of the lg logo. Recovery gone, reset did not work, download mode worked though.
Used the lg offline mobile tool and found uk41011a.kdz Yay unbricked. Problem is though, its an AT&T tablet with us cellular firmware. My Sim card is now unreadable since it is an att Sim.
Any ideas?
bethnesbitt hey! I really need that us cell kdz can you post it? please? lol

Mine is bricked hard so right now its a paperweight. If you use the UK might be able to work unlocking the bootloader. Just turn off tab, hold, either just vol up or vol down, cant remember exactly then hook to PC. In fastboot do OEM unlock.
If using att then the v41007h will work with your att sim. If its a vzw tab, then get the vzw stock kdz. If its a att tab the vzw doesn't work right, wouldn't waste the effort. I tried and it asked for a PW with the vk kdz flash.

To get fastboot I take it I have to be rooted?
Looking into that now, I bought this tablet with 5.0 rooted with Kngroot and when I ran Super Su that's what bricked Me to here.
This US Cellular from isn't bad can I use their network now?(not a fan of AT&T)
I thought I saw a post that had the actual AT&T kdz however if U say I can unlock the bootloader on here I will stay. Or did U mean sim unlock?

Same issue here. Trying to go back to stock and no luck. I did the debug kdz after the stock rom I tried did an OTA update and got stuck in TWRP. Installed the same stock ROM, flashed stock recovery, and unrooted. Still every time I try the OTA, it tells me I am suspected of rooting. At least it doesn't get stuck in TWRP anymore. There has to be some kind of efuse in this tablet. If not, I still have no idea what I need to get rid of to do the OTA update and get Lollipop.
Hi everyone in this incredible web!
I bought the LG G3 D850 AT&T kitkat (T-mobile logo on the back), and flashed the D855V Marshmallow with LGUP.
I get this message "current version is not available for user. Can't find matched cust for NT-code mcc/mnc [310410] subset [FF]"
Since then the SIM card will get no signal. I've tried every possible thing to flash any rom that will work.
Anybody can help me, please??
Many thanks.

I'd restore to stock KitKat and start over if I were you.

Have you confirmed if the device is truly ATT or T-Mobile? You should be able to double check under the battery. Once you know that, download the correct tot file, throw it in download mode and restore using the tot file.
Well dear. What my friends are sying is true you should flash a stock. Firmwere via downloading mode and it will be. Ok. If it still not working than. Go to mobile softweres shop the. Can make it good like u want

They are you able to help me out and send these links so I can put a custom rom on my smj337r4. I wanted to put lineageos on but it doesn't have one for mine.
