Ok... I've spent about four hours searching and can't find the kdz anywhere I get a message saying I don't have permission to access the files on the lg website. A direct link would be cool

I should alao say that I'm an idiot apparently and can't download the zip on mega... no download button....

I have the x and u boots as a flashable zip thanks to [MENTION=4447066]kuma82[/MENTION]. If you'd like, I can send them to you. They didn't improve it for me though. Still impossible to unlock. Such a shame. I'll be sure to check if a bootloader is unlockable or not before I buy a phone next time!

Go to General Section -> KDZ Repository with stock ROMs (made by cmahendra). You can't miss it, should be near the top.

I'm going to try flashing the European ICS again. There is a success story unlocking a P769. After that, I'll flash euro 20b and wait 35 minutes with only data on.

Soooooooo. . ..are you on PAC ROM yet?!:D

I see that they have some more ROMs for the P769 but are they really good? I mean is all of this work and trouble really worth it? If I wanted to go back to stock would it reverse the unlock? If not will it security error my phone? Can I move freely from stock to Cyanogen to Pember to PAC to stock again? The phone before this one has already unlocked and I had no trouble going to from stock to cyanogen to stock again. . .this is different. I would appreciate some insight from people who are unlocked. :confused:

I have a P768 and trying to do what some folks sugested: flash 10g euro enable debug, then 20b euro, wait 35 minutes and try to unlock. But i think my pone is acting kinda strange:

i'm in 10g right now, when i go to settings/software update and ask it to search for updates, came a message saying that i'm already using the latest software version available (strange right? why did it not tell me there is a JBout there waiting for me? I'm on euro software)

Then i went to hidden menu (3845*#760#) > ModuleTest > FOTA Test > DM Test > Default Server Setting

- This is what returned:

View attachment 2373843

Strange or is this normal? If not, what can i do to restore t back to normal? I've already tried hidden reset and factory reset, nothing changes there.

Someone who successfully unlocked the BL can check this settings i mentioned and tell us if the page doesnt open either?

My laptop is recognizing my phone as P760 ever since I tried flashing euro 10A before. Maybe I'm on the right path?

[LG Optimus L9 P760, P765, P768, P769] shucrut:
Well, it didnt work.. again

I really hope that people out there succed trying to unlock their BL, but i give up. This phone mad eme think about LG in every new phone i bought. I will just wait for my S3 arrives and give this L9 to my wife. The good fuc**** thing is: here in Brazil we don't even have an update to JB and flashing a JB from another country the phone lose connectivity with carrier randomly :D I can't tell how much i love you LG

I'm going to go through the process without copying over the root bin while flashing 20B. No luck with P768. Now let's see what happens with P769.

[LG Optimus L9 P760, P765, P768, P769] matthewstice:
I startedd with 21d(out of box)

Flashed rooted 10g and

Setup everything(debug/show touches/touch data/ artas cwm Installer and settings shortcuts on home screen to make it easier with the wonky touch screen . Also busybox installer and busybox on same home screen. Prepare well for flashing to 20b.it saves your home screen apps and settings( saved me a lot of time and frustration)

. Make sure ur radio.zip is ready to be flashed and is on ur SD card if u have no signal on 20b..disable screen timeout in display and keep awake while charging(I think in develop settings)..then.. Flash to 20b.. Make sure u root while flashing by replacing with the modified bin files..Enable WiFi (i did before flash and itt stuck on 20b)and make sure u have radio signal..update the su binary after u open supersu..keep phone screen on whole time..plugged into PC..with adb open ..confirm u get your device to show up with adb devices command... Wait 1 hour.. Then issue unlock command..worked first time for me...but then again I'm wind mobile..canada

After u unlock it I'm pretty sure it stays unlocked for good..

I tried to flash a kdz to get the phone back to stock..but my adb shows the device as offline for some reason ..

I can not get the lg support tool to pick up the phone and I'm not sure why..after installing penderrom amd cm 10.2 etc..and my new cwm touch recovery....but I will figure it out..not a big deal atmm..
[LG Optimus L9 P760, P765, P768, P769] LaDY Vengeance:
Here's what I did.......

1) Used fastboot to erase everything.

2) Used fastboot to flash P760 u and x

3) Used offline flash method to flash euro 10G

4) Did a hard reset

5) Disabled lockscreen, switched timeout to never, enabled usb debugging, show touches, switched to LG software mode

6) Used offline flash method to flash euro 20B

7) Since cannot get solid connection with data, turned on WiFi and opened browser to make sure there is a connection

8) Now I'm waiting 35 minutes before issuing adb reboot oem-unlock

I did not root to see if LG is detecting a change in the xbin folder. Let's see what happens.

---------- Post added at 02:37 AM ---------- Previous post was at 02:25 AM ----------

It didn't work. Epic fail for the P769. I quit.....there is no way to unlock. I'm trading this crap for my dad's Optimus F6 and wait for development. At least I can root it and have LTE. At least with the F6, I don't have to worry about European kdzs and wonky touchscreens.

---------- Post added at 03:34 AM ---------- Previous post was at 02:37 AM ----------

I can't sleep so I'm trying a little experiment. I just erased everything with fastboot and went directly to flashing 20B. Then, I chose option to flash P760 JB u and x because it says it gives the P768 ability to unlock. After this, I'm honestly done.

I think I'm going to try that. . tonight I'm going to factory reset, delete cache, delete Dalvik cache, format system THEN install v20b euro open. . .let's see if that works for me.

---------- Post added at 10:06 AM ---------- Previous post was at 09:23 AM ----------

Honestly I think it has nothing to do with the procedure but everyting to do with the phone. There is a factor that some phones have that we cannot simulate. Albeit fast reboot or fastboot window or something that helps to achieve fastboot menu within the time frame needed to unlock.

I see your steps but it doesnt make mention of flashing the radio? As I mentioned before this was one of the different things I did (which may be significant) and it worked for me. I mentioned the version SIC 1227 is the one needed for V20B. Of course the raido is flashed via cwm so you would have to have root on V20B as well. I was hoping you would finally unlock it. :(

After viewing the hex for the boot block, mmcblk0p7, i am seeing some random bits that do not reference anything in the hex code. Of course there is the leading 01 hex bit. But what im finding is a 06 in a random spot in the middle of nowhere. Also some 01 and 02's in a random middle of nowhere. By nowhere i mean in the middle of 00's. Wondering right now what those bits are for. No obfuscation in the boot block surprisingly.

That could work. It seems to be the way the L5 is unlocked from reading the instructions of its unlock procedures. BTW thank you Lady for the reference to that. :) I just thought thought about a possible issue. The mmcblk0p7 block has your IMEI number inserted into the code. Each person might have to change the code to match the IMEI number. Also the mac address for the wifi is also in the mmcblk0p7 code. Hmmmm. LG you are evil!!!

No, 7 is the boot block for our phone. mmcblk0p7 is linked to nv if you look in /dev/block/platform/omap/omap.hsmmc.1/by-name/nv. 1 is xloader and 2 is uboot as linked in the same folder.

Проверка подписи работает так же,как и на lg optimus black(u-boot проверяет подпись boot,x-loader проверяет подпись u-boot),но подпись x-loader на L9 тоже кто то проверяет(параноидальная какая то безопасность)

Payback не знает кто проверяет подпись x-loader,он начал ломать,но бросил.Ему видите ли надоело

Gryff302 утверждает,что подпись x-loader проверяет nv.img.я скинул ему два nv.img для сравнения.И вообще надо посмотреть,что там за код,нужен ли дизассемблер,или можно обойтись hex редактором,или просто заменой

I did the same with the modifies x&u and the phone still doesn't respond, even thought the nv.img is not present. If the nv.img is responsible for verifying the x-loader and the nv.img is erased, the phone should perform like the unmodified x&u (boot into recovery).
