still cant unlock my bootloader lgms769 (metropcs) :( i have the v20b kdz flashed waited over an hour and no go.
[LG Optimus L9 P760, P765, P768, P769] zironia:
Downloaded and flashed the 20H open Euro KDZ. Had Edge signal for the whole time. Waited an hour and ran adb reboot oem-unlock. Just rebooted. =( This phone is driving me crazy. Will be very happy when someone figures out why so peoples phones unlock and others just reboot.
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:
Someone really needs to release another video tutorial. This is just ridiculous. I've only tried this method once but when i did it i had to do a hard reset. I have no idea which kdz to use eithe, help? I would really like to get CM on this thing, the stock rom is way to ugly and has to much bloat.
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:
I got the screen inverted and the recovery installed but when i try to boot into recovery it wont, it just boots back into the stock rom. I even tried holding down the volume button and it didnt work, and yes im rooted. I dont get what im doing wrong, it should be right according to this: http://www.hackmyandroid.com/clockworkmod-recovery-cwm-for-lg-optimus-l9/4086
[LG Optimus L9 P760, P765, P768, P769] MoonMaster345:
Install busybox after you root, then reinstall recovery

get the apk and try to install it through the file manager if you are inverted.

so

Busybox -> Recovery -> Reboot -> Blinking -> Press down -> ??? -> profit
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:
Nope, it just boots me into safe mood, wtf?

BUMP anyone? im kindof in a hurry

---------- Post added at 05:05 PM ---------- Previous post was at 04:55 PM ----------

OKAY i finally figured it out, i have signal and forgot to wait 30 minutes and run the command. I'll do that now. So i just run cmd as admin and run the command?
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:
again fail, when i issued the

adb reboot oem-unlock

command it rebooted and didn't say anything about unlock, im going to do a hard reset and try again Friday, hopefully then it will work.
[LG Optimus L9 P760, P765, P768, P769] isaacj87:
A couple things I made sure of before I tried running the unlock:

- I noticed that you guys mention you have signal, but do you have a data connection? (I turned WIFI off)

- When you let the phone sit, was it connected to the PC while the phone was in LG Software mode?

The CM dev that posted about the Euro version (P760) unlock process said this:

Here's the link: https://plus.google.com/115049428938715274412/posts/CUu6YE3C6C2

Not trying to spread FUD, but it's possible your phone(s) has been locked out after so many attempts. Again, I can't say this for sure. For the record, I did this on my LGMS769 (P769 "Metro's" version), and it worked the first time. The only thing I made absolutely certain was to have a data connection, have the phone connected to the PC in LG software mode, and let it sit continuously for 45min-1hour.

Don't give up, guys... I'm sure there's a solution out there. :(
[LG Optimus L9 P760, P765, P768, P769] cubemike99:
Where can I find CM for the l769? All I can find on the CM site is a version for l760. And what exactly do I need to flash it? I've updated to V20f, rooted with lgpwn.apk, installed busybox, installed CWM, and I can press volume down when the leds flash to get into the recovery menu. Do I still need to do flash V10G, flash V20B, etc if I don't care about a carrier unlock? All I want to do is install CM. Thank you for the help.
[LG Optimus L9 P760, P765, P768, P769] isaacj87:
The bootloader will need to be unlocked in order to run custom ROMs like CM10.1. It sounds like you've only achieved root access. FWIW, here are CM10.1 (stable) and CM10.2 (unstable) ROMs for our phone. I'm running AntonX's CM10.1, and it's quite stable.

Oh no.

I assumed that since I could open CWM I was golden. So I installed the stable zip that you linked. Now when I turn on the phone the LG logo appears witht he words "Security Error." Please tell me I can restore back....
[LG Optimus L9 P760, P765, P768, P769] quickfastgoninja:
Can you elaborate on this? What method did you use to get unlocked BL and root?
[LG Optimus L9 P760, P765, P768, P769] omgbossis21:
Does 10g recognize an unlocked bootloader? And what exactly does it take for 20f to recognize it? I really need somebody to host the gpt1 and gpt2 partitions (mmcblk0) for me..... I extracted 10g and those 2 partitions contiain lots of information all pertaining to the bootloader and its signature checks. I need UNLOCKED p1 and p2 partitions preferably off a p769 but the 760 will do. From what I can tell those two partitions handle all the effuses...... O yea you cant pull them while the phone is running, you need to boot into recovery and pull them that way.
[LG Optimus L9 P760, P765, P768, P769] kuma82:
You mean you want the x & u partitions? I gave you those a long time ago. Nevermind, I'll pull those later and give them to you.

[LG Optimus L9 P760, P765, P768, P769] omgbossis21:

---------- Post added at 06:09 PM ---------- Previous post was at 06:01 PM ----------

Also the first 3 under mmhs1 ones says mmcblk0 mmcblk0boot0 and mmcblk0boot1

---------- Post added at 06:11 PM ---------- Previous post was at 06:09 PM ----------

If you don't mind your u and x as well. I have so many I'm not sure which ones came from you. After reverse engineering these partition I think this is gonna work.
[LG Optimus L9 P760, P765, P768, P769] SomeGuyInOz:
I forgot to mention, though I think they are irrelevant:

- While I was waiting the 30-40 minutes my phone was connected to my WiFi network

- I had the screen set to NOT turn off/sleep

- My SIM card was in but I had no radio because I had not flashed the radio.zip for our P769

- The SIM card I used is NOT a T-Mobile SIM - it is an Australian SIM card (I did this at home in Australia)

I doubt any of the above matters, but I thought I'd mention it, just in case...

I'm still surprised this worked for me first go. I wasn't expecting that! Keep trying guys. I'm sure someone smarter than me will figure it out.
[LG Optimus L9 P760, P765, P768, P769] omgbossis21:
If I get these partitions I'm asking for I'm basically gonna nuke all bootloader related partitions and flash the unlocked ones. I will reverse engineer each file to make sure I'm not flashing another's info first.
[LG Optimus L9 P760, P765, P768, P769] kuma82:
I'll send the partitions. Hey have you checked out my kdz extraction guide? It extracts a gpt1 & 2 and it has 512 k of data.

CM 10.1 P769
[LG Optimus L9 P760, P765, P768, P769] omgbossis21:
Yes I've been using your guide and on 20b p1 and p2 are empty. 10b they are filled with data. I've already tried flashing them empty and it didn't work which is why I wanna see if your p1 and 2 are empty after being unlock. The other 3 partitions I haven't open yet but all seem to be apart of the bootloader system. Your guide has been very helpful :) my thought here is one of these partitions must control the efuse. I try one at a time until I see unlocked. Though I'm on 20f I suppose your x and u will tell me bootloader state in software upgrade mode? Or do you push the 10g x and u to see unlocked in menu?
[LG Optimus L9 P760, P765, P768, P769] kuma82:
The unlock in hidden menu only works in a couple of kdzs' and the only one I remember seeing unlock is the 21b Canada, and I had the 20b Euro u-boot. I think I remember checking it again with the 20f u-boot and it didn't show unlock. I think. give me sometime to get the images for you.

CM 10.1 P769
[LG Optimus L9 P760, P765, P768, P769] omgbossis21:
OK no problem. Technically if it works will I see bootloader unlock on the software update screen? I figure after this either my girl is buying my phone or I'm gonna mod cm10 for 2int. Docs put me on predinosine today and this first dose has me way over simulated, glad I got projects everywhere hear lol
[LG Optimus L9 P760, P765, P768, P769] kuma82:

I think we should move this discussion to your guru thread.

CM 10.1 P769

Will continue on in code guru thread
[LG Optimus L9 P760, P765, P768, P769] RustyKungFu:
I have not fully understood the purpose or reasoning behind the wait process of 30 minutes minimum before issuing the "adb reboot oem-unlock" command.

When I have done this procedure the device I was working on I did not keep it connected to the computer while I waited, and in some of the instances I did not have a sim loaded. Maybe this is the cause of my having failed to unlock the P769 I was working on. :confused:

The possibility the phone has been permanently locked out, is terrible.:eek:

After having failed this last week, I flashed V20F to the device, applied the screen fix and corrected the LG boot logo, left the phone rooted and gave it back to my friend. (I think he is rather annoyed that I take his phone and return it with 0 results, so I think the next time I reattempt is when their is clarity and certainty in the method and procedure to unlock the bootloader that is also consistent)
[LG Optimus L9 P760, P765, P768, P769] elpuertorro:
As i stated in my post i tried for 3 days until i got it so i doubt sending the unlock command locks it as i sent it plenty of times.

what's has been stated is the sim is in but some of us don't have the cel signal because we have NO RADIO, so sim is in but no cel tower signal reception.

And again issued the unlock command plenty of times for 3days and on the third day after getting and flashing the x and u and running the procedure it unlocked!!

So don't give up we don't know what makes this phone tick and unlock, but eventually it does, some get it on the first try some of us after 3 days but we got it unlocked, so keep trying and good luck!

Just figured i would point it out as someone reading your statement could get confused and assume that his phone is unlockable when it actually is! ;)

now on that note good to see more done for this phone..keep up the great work guys!

---------- Post added at 10:33 AM ---------- Previous post was at 10:26 AM ----------

i mean you should be fine following carloswii5 video minus the 10g flash part but you do realize this is unlock for P769 right? ;) so unless someone here has your same phone i don't think there is much we can help you with as we get a set of issues when trying to unlock that are unique because of using the eu open KDZ made for the p760.

take a look around under your model number p760 you should find better help for your phone. good luck!
[LG Optimus L9 P760, P765, P768, P769] shucrut:
You're assuming everyone who can't unlock the bootloader is dummy/lazy.

I saw this when i asked you for help. Many people here tried almost everything. You got lucky and your phone unlocked, but many users tried every single method and still bl is locked. Just ask omgbossis21, so he is a dummy/lazy too? Not everyone say crap before searching, you should know that. I think you should be more humble. You said you tried 3 days before unlock. I tried for over a month every method in this forum and im sure im not the only one.

And i don't give up, i wil continue trying every new ideas i found here or anywhere else
[LG Optimus L9 P760, P765, P768, P769] Meda808:
I dont see him as assuming everyone who cant unlock is a dummy/lazy.. i see him saying two things. 1. This is a P769 thread. and 2. No Unlock option implies that there are users who will wonder if their phone is a model that cannot be unlocked and unless we know that as a fact, it can be misleading to new users. It gets tiring trying to help people when it's obvious they do not search.. so in that regard, yes.. people are lazy. I got tired of linking the same crap multiple times because people dont search for the answer. most questions have been answered. now that i've said that someone please start a 'should i buy this' thread.

That's what i posted

Can you tell me where did i call him lazy?? plus did you noticed the question that was asked?? just because i told him not to say it's unlockable because that would confuse people is calling him or assuming his lazy??? really?? ???

Again please point out where i assume that they are lazy!!!

it's not my fault you had a bad experience i did try to help you along the way. but i do not own a p768 like you or the person i told to look for his specific model info as that's where he can get the help he needs! is that assuming he's lazy for referring him to where he needs to go???

I mean thanks for trying to call me out. and you assume i don't like to help i have a surprise for you in a few... but meanwhile let me refresh you our conversation to see if i was justified on being mad when i keep telling you, do this and you came back with i did it and also did this other stuff and now i have x problems, then i tell you you don't need the p769 stuff you need the p768 i even gave you links for your phone after the fact that i was mad because i keept telling you what to do and you keep doing other stuff but if that's being an A** well i guess i am

[LG Optimus L9 P760, P765, P768, P769] isaacj87:
OFF-TOPIC: I see some interest in 2nd-init. If you're interested, I have a device folder (LG Spirit MS870) that uses 2nd-init. You can the process works, and create a modified 2nd-init for the P769. Then, you can build a ROM with the new 2nd-init with AntonX's or BobZ's device tree.

*NINJA EDIT*

I think that was a working 2nd-init, but I can't remember now (don't have the phone anymore to test it). I'm no expert on 2nd-init, but, essentially, the "meat and potatoes" stuff is located in CM10.tar. Unpack a stock boot image, and fill CM10.tar with the relevant files needed (e.g. uevent, inits, etc.). from said boot image. Since all the hard work is done (working CM10.1 on our device already), just building a version with a correct 2nd-init and stock boot image *should* get CM10 working on a locked device.

NOTE: The 2nd-init I have in my repo is older (jellybean branch). You may want to use something newer if it exists.

NINJA EDIT: On second thought, here's a better base to work off of: BobZ's CM10.1 tree (for the LG Motion): https://github.com/BobZmotion/device_lge_l0/tree/cm-10.1-hk/prebuilt/xbin
