Well, I've spent every free minute I've had wiping, flashing, waiting, rebooting, restoring and maybe crying a bit. I've tried numerous methods, orders, u&x stuff, magic spells, pixie dust and unicorn blood. This damn thing is obviously not going to unlock. You win LG; I give. Next time I need a phone, I'm going back to Samsung.

Also just noticed my phone has a date on the sticker under the battery "11/2013" So maybe these newest phones just can't be unlocked anymore? I dunno. No PACman for me.

I feel your pain, hun. I miss CyanogenMod, too. There are a few of us stuck in this prison for now. :(
[LG Optimus L9 P760, P765, P768, P769] travioso:
Mine says the same.. did you by chance try the V20A_00.kdz? The Indian one.. supposedly there was luck with that one too besides just the V20B.. I downloaded it to try but don't have time to get to it any time in the very near future.. (Can't go through all the recovering from crazy screen if it doesn't work) Plus, if it's been tried, well, I can save myself the hell of doin it for nothing :)
[LG Optimus L9 P760, P765, P768, P769] Zhono:
If you make a good cwm backup, and keep the extra files on your external sd, recovering from the messed-up screen and whatnot is actually very fast and easy. 10-15 minutes, max. It's been the only good part about this whole process for me.

As for the Indian rom, nope, never tried. All of the guys that know what they are doing have said it has to be the 20B European open rom only, so I never bothered trying any of the others. In the KDZ thread there is also a newer European open rom, 20f I think, but I never bothered with that either. Pretty sure it's just that one rom that is supposed to work.
[LG Optimus L9 P760, P765, P768, P769] travioso:
That's what I have seen too.. But cmahendra (think thats how ya spell it, sorry if not) said something about it at the top of this post http://xdaforums.com/showthread.php?t=2221102 as far as 10-15 minutes.. you talking about putting busybox and the likes on the sd card and installing via adb? i did all of it through that wonky screen (setting up play store to download them.. couldn't find the actual apk's from a trusted source)
[LG Optimus L9 P760, P765, P768, P769] Zhono:
If you search a few pages back, you'll see a tool made by Kuma82. He made it extremely easy to root, install busybox, and cwm with pretty much no work. Enable usb debugging and LG software mode for USB, and just run that tool. Then you can reboot into cwm and restore/flash easy. I guess he's still working on it(more features maybe?) but it works great as it is, for what we need. Since I can't unlock, I'm checking out his tweaked stock rom as well. Just need to figure out how to remove the sd swap feature first.

Honestly though, I've gotten so used to using the messed-up touch and backwards screen, that when I restore my phone to stock, I get confused. lol
[LG Optimus L9 P760, P765, P768, P769] travioso:
Cool I'll look for that post.. Probably end up trying that indian v20 sooner then later then and hopefully pop back on here with good news.. Yeah I just flashed that stock rom not too long ago.. Nice, gonna see about overclocking soon.. And yeah, after going through the whole setup of the phone (and attempting to call 911 a few times at first before yanking the battery) for a good while i kept catching myself hitting the wrong parts of the screen lol.. Ya get on a role with it :) Thanks again..

Hey guys long time no see.. i was thinking, does the 2nd init recovery have the boot to bootloader option? If it did you guys could give it a try and see if it would boot up to it on v20b..

I don't believe it does, but I have a similar theory, buy it won't be easy having to go thru the wonky touch screen...

But as for my theory,

I was thinking what if we installed xposed installer, and get the wanam module, and made our phone use the "advanced reboot" option so when powering down it would say

Reboot

Reboot Recovery

Reboot BootLoader

Just a thought...

[LG Optimus L9 P760, P765, P768, P769] Gryff302:
Wouldnt the advanced power menu booting to bootloader equate to using adb reboot bootloader? if so then it will just reboot back into the android.

[LG Optimus L9 P760, P765, P768, P769] LaDY Vengeance:
Hahaha...I wish you the best of luck.....as far as steps go....hmmm. I would try doing everything the video shows but instead paste over the radio during the flash process instead of rebooting to CWM. There seems to be a universal method LG uses which includes never rebooting and to let it sit for 45 minutes with active Internet connection. If you manage to unlock go and play the lottery...lol!

I bricked my phone trying to flash a new recovery and managed to get it working again using fastboot. I learned that through this annoying unlocking process lol irony
[LG Optimus L9 P760, P765, P768, P769] boo_radley:
Can the reboot be haulted or stopped in any way?
[LG Optimus L9 P760, P765, P768, P769] shinobisoft:
NO. It reboots because of a simple '#if' in the source code. The '#if' is causing the code to jump completely over the 'oem-unlock' option for fastboot. As I mentioned in a previous post, from the source code LG released for V20H, all L9 variants are permanently locked out of the bootloader except for the P760.

Someone may eventually figure an easier way to unlock these bootloaders, but it will never be as simple as 'one click' like most of us would like.

I haven't completely given up. I have some ideas. Just gotta experiment a little still...

Bootloader unlock requirements?

So does anyone know any definitive requirements for unlocking the bootloader? I have stock ics but had updated to 20f, and can't seem to unlock. Am I just not trying enough? I left the phone on overnight after flashing but nothing. This is my second android phone, and almost considering the easily jailbreakable iphone, as much as it pains me to admit it. Thanks LG.
[LG Optimus L9 P760, P765, P768, P769] AlbinoCookie:
File on the mega upload is 666, and this if a file containing everything to unlock the bootloader on a phone made by the devil. Makes sense.
[LG Optimus L9 P760, P765, P768, P769] travioso:
This may seem like a completely idiotic question as this is way outta my area of expertise.. and probably been tried.. could it be as simple as hex editing one of the .bin files during offline flash method? similar to lelus' root method.. null out that line.. one last question.. i saw something from a way older post that said something about a cpu flag being set for unlocked bootloader (which can't be undone, by lelus), could new versions of this phone (i'm on metro pcs v10d as stock out of the box) have a flag set for just NO? been trying for 4 hours AGAIN to unlock it on v20b.. even gone as far as to fastboot the the p760 u+x for JB.. flashed kuma82's radio fix so i have service.. tried hour on wifi, hour on data, hour off wifi, trying one last time on data before i go back to stock for the night.. hoping santa clause leaves us all the secret of unlocked bootloaders tonight :)
[LG Optimus L9 P760, P765, P768, P769] Zhono:
My guess is, if it were that easy, we'd all be unlocked and flashing custom roms already.
[LG Optimus L9 P760, P765, P768, P769] travioso:
yeah i know.. had this thing for a little over a week and about to throw it into traffic over this bootloader epidemic.. trying to think outside the box.. figured these guys have tried it so just wondering.. i'm starting to think its not completely software controlled.. i'm on u+x p760(jb version..), v20b, so by theory it should unlock (my stock came with v10d from metro.. went to v10b then to v20b now.. THIS time lol) .. i'm a noob by all means when it comes to some of this stuff.. have been guinea piggin myself and if i see this damn thing just reboot one more time lol.. well, you get my drift..
[LG Optimus L9 P760, P765, P768, P769] shinobisoft:
No, not that simple. When the ROM is built, for all models other than the P760, the ability to boot in to fastboot is removed. Meaning, the code that is responsible for loading and starting fastboot doesn't even exist as it's NOT included.

[LG Optimus L9 P760, P765, P768, P769] boo_radley:
If fastboot code doesnt exist maybe LG used an alternate type of fastboot. It seems to be integral, the fastboot, so if the code is missing, seems alternate path is taken. It just seems so fishy lol.

:eek: OMG....really?
[LG Optimus L9 P760, P765, P768, P769] shinobisoft:
OctopusBox claims it can unlock the L9s bootloader. However at about $40 for OctopusBox itself and another $40 for a software and cable bundle, and well it's not worth it. For me, if I did this, that would put me at about $300 invested in this phone. Not worth it.

SmartCard is another alternative, which I believe it what LG uses. I've noticed alot of smartcard related stuff on my P769. I haven't looked in to SmartCard yet to see how costly and feasible it is.
[LG Optimus L9 P760, P765, P768, P769] Polloos:
2nd-init is another alternative, I managed to boot a modified ramdisk and recover, but not zimage.

Cm10 is possible boot, but I think not the zimage, the motorola defy used this method to boot the roms, its possible port it

I have the P760 but my bootloader blocked it on sat :( LG Spain told me that they are working on 4.3 but no dates

Sorry for my english, i'm using Google Translate
[LG Optimus L9 P760, P765, P768, P769] shinobisoft:
L9 already has a 2nd-init recovery just no 2nd-init ROMs. I/We know this is a possibility, but the damn thing would still be locked. 2nd-init runs after the kernel is loaded to RAM. There is already a kernel there that why we can't boot with new kernels.

To go the 2nd-init route, I think we'd also possibly need some kind of boot menu to allow choosing to boot 2nd-init recovery or 2nd-init ROM and possibly boot default system ROM.
[LG Optimus L9 P760, P765, P768, P769] kuma82:
The ones that created the CM9 2nd init rom (artas182x and a couple of others) already came up with a way for the 2nd init recovery & ROM to coexist. If I have some time I'll find all the info on the subject.

I had unlocked the bootloader, I made a simple mistake somewhere. It's a good thing I have had other experiences messing up on other phones. I think it was that I had forgotten to flash the superuser.zip file so for some reason it wouldn't let me do something, which I think was jump into non oem recovery. So maybe I hadn't fully unlocked the bootloader now that I think of it. I think I was forced to send commands using fastboot. Anyways I have fixed my brothers phone. Thanks for your guide man. :victory:
[LG Optimus L9 P760, P765, P768, P769] sammyz:
Alright, I tried adb reboot oem-unlock before and after 30 minutes.....nothing :(

As soon as it reboots, the buttons' LEDs blink repeatedly for a second, then turns on.

Yes it is rooted, yes I installed the radio.zip and cwm_ts fix.

This is an MS769 that went to the newest update, flashed to Europe firmware, then flashed to T-Mobile V10G firmware (as this guide says to flash to that firmware first), and back to Europe firmware.
[LG Optimus L9 P760, P765, P768, P769] Alucai Vivorvel:

...... So does this method work for LGMS769 v10e? Do I have to unlock bootloader in order to flash CM? I got it to root using the chinese method, installed SuperSu and gave SS root permissions. Installed CWM recovery and made a backup of everything. Where do I go from here to get CM 11 android 4.4.2?

recap:

Rooted...check

CWM recovery backup.... check

unlocked bootloader.... pending

Custom Rom flashed..... pending

what do i need to do?:confused::confused::confused:
[LG Optimus L9 P760, P765, P768, P769] shinobisoft:
Yes, in order to install CM you will need to unlock the bootloader. As to whether this will work for your device and software version, that's actually hit or miss. There has been no consistency between the devices that have been unlocked with this method.

confusion is killing me

when i rooted my phone(LGMS769) with the chinese program, the program clearly says "LG p765(optimus L9)".... now i thought the LG MS769 was the same as a p769.... that is the confusing part.... how do i know which one i have? ms769=p769 or p765?

supersu installed and given su permissions made it a system app, busybox installed, CWM recovery installed and backup made. just need to get the bootloader unlocked and flash CM to run kitkat. are there different ways to unlock the bootloaders for the different versions of the L9, i.e. p76x?
[LG Optimus L9 P760, P765, P768, P769] shinobisoft:
The P769 and MS769 are one in the same, just different carriers. P769 being the TMobile variant and the MS769 being the Metro, I think, variant. There are several different methods, all with the same end result, an unlocked bootloader or a still locked bootloader. As mentioned previously, there are no consistencies as far as unlocking the bootloader on these devices.
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:
That can easily be checked in Settings - About Phone - Phone Identity

Youd better hope you have a MS769, you might have a better chance of unlocking then. Of course that's with the assumption that it is different.
