i'm trying to unlock the bootloader but when i get to the shttp part, my windows 8 laptop doesn't know what to open it with. Also i put "UpTestEX_mod2_marwin" in compatibility mode and try to open it as admin, but it doesn't open

ahhh, i had to mess with mindow8 last night for the first time - bleh! my brother got tired of me borrowing his windows7 laptop.

insize that zip folder is an MSXML installer - you have to install that first - i figured it out by pure chance - if i didn't notice the installer, i never would have thought to try it. btw, try this guide later: http://xdaforums.com/showthread.php?t=2461483

I don't want to be a d*ck but you did post the link to your tut on carloswii5 tut post page and not give him credit or even mention him??? :confused: :eek: Many of us unlocked thanks to his tut and vid, the least you can do is give him his props!!

Or also the original guy who did this which if not for him none would have the p769 unlocked Ricardo Cerqueira. great resources on your post but please properly give credits to ALL and if you link to a post thank that person also don't only link the post and that's it. just friendly advice.
[LG Optimus L9 P760, P765, P768, P769] villan.co:
that's because this tutorial was useless for most people, including myself, so, i linked to another one which may help them. i borrowed nothing from this tutorial, and cited places that i did get some information from. i owe him nothing.
[LG Optimus L9 P760, P765, P768, P769] villan.co:
alright, this is the last time i'm wasting my time on you, go re-read the unlocking the bootloader section:

this part of the guide was started last night, in a flurry of excitement - ignore it until i remove this message, because i know a lot more about it now, and need to spend the time heavily updating this and expanding upon it. don't just sit there all night spamming the command, it only takes 1 minute - i mentioned that in my other thread, but after every one already read the original wording, which makes it sound like you have to do it for hours - you don't, it take a couple minutes, at most. just wait until you see the guide updated. there is a lot more info that will help you, and it's on the way. i keep getting pulled off by little tasks and replies, etc. THIS WILL WORK FOR YOU, I CAN ASSURE YOU OF THAT, BUT YOU HAvE TO LET ME FINISH IT...
[LG Optimus L9 P760, P765, P768, P769] elpuertorro:
Last time?..wow must of lost track of time..i was almost sure I just posted 1 post before this 1 about your tut...hmm or maybe some others have said the same to you and i was the only one who told you in public for all to see and your tired of it? don't know but i guess you have very little patience maybe...

I see you're attention to detail, maybe you missed mi sig where it says i'm UNLOCKED using carloswii5 tut where we are posting on and running leolawliet's PenberRom5???

Well let me not distract you maybe like that you have time and you can provide the sources of all this new info.. and just to correct you i'm actually a smart f*ck or at least i like to think so, but just remember "it takes one, to know one" :good:

By the way why post incomplete stuff?...make txt file format you're info then when COMPLETE post on the forums just a friendly advice. from a so i think of myself smart f*uck to a proven Dumb one that does dumb stuff and post incomplete and misleading info .......yeah that's a really smart move there mister shows you are not dumb at all :silly:

here's an example just to prove my point

DO NOT flash the v20b( i'm guessing euro unlockable one) rom unless you are prepared for a long fight with an unusable phone

Funny as this and 1 or 2 others are the only ones that would allow the unlock as the TMo US rom won't allow it don't take my word for it you can ask [MENTION=2159458]Lelus[/MENTION] or [MENTION=4447066]kuma82[/MENTION] unless there's something new i haven't read about.

But then a little further below in the steps we find this:

"FOR NOW, you need to flash v20b.kdz using LGS (LG Software) on windows - i'm looking into a workaround for linux only methods that will allow you to do the same thing via CWM recovery instead of LGS."

:eek: seriously so which is it we do or we don't need it??
[LG Optimus L9 P760, P765, P768, P769] omgbossis21:
The guide is lacking and so is the credits. That will rile up alot of people.... I think you either got lucky and have one of the phones that can unlock or the other possibility is the command don't always work the first time. Last option is kuma was right about our reboot speed and catching the command before full boot may work. As far as new information I've seen none. Anything technical feel free to post in code guru thread under android development.
[LG Optimus L9 P760, P765, P768, P769] dragid10:
When i try to flash 20B, it goes into S/w mode and updates normally. I copy the new .bin into it, but the update process gets stuck at 10% then says it can't connect with my phone anymore
[LG Optimus L9 P760, P765, P768, P769] LaDY Vengeance:
That's exactly what I was thinking in terms of the boot up speed. Maybe with our models, it's just not processing before the boot.... I did notice that on the carloswii5 video, the logo comes on and a second later, goes into fastboot.

[MENTION=4056938]elpuertorro[/MENTION], thank you for clearing this up and looking out for us. I had a funny feeling about this new method but I guess I got too desperate.
[LG Optimus L9 P760, P765, P768, P769] Meda808:
i did the carlos method and it took one try. the only thing I did differently was not using fastboot to install recovery instead i installed artas cwm. my phone shipped with 10g

No problem I do read all post in threads that I follow and specially NEW stuff that might help us, I haven't even put my tut up (the one i sent you) because is lacking stuff and i don't want to mislead and here comes this character with that crazy post!!and just some crazy stuff put together from all over and not proven to work by anyone but himself, not only misleading but also making it worse for newbs or even experimented people, like me i had plenty of experience with odin on samy and htc phones also but this LG was a whole new ball game for me. had to star kinda of from scratch.

And thanks to carloswii5 video mostly, Lelus, Artas and kuma and other tuts made me understand better.

and then hijack this thread and not even give credit to him or artas for that matter, that is just dead wrong! and makes him a cocky a**hole in my book! < sorry admins if I went over board feel free to edit.
[LG Optimus L9 P760, P765, P768, P769] LaDY Vengeance:
I'm going to give your method another shot tomorrow. I have this feeling that some P769 phones have a different boot up speed and somehow not able to execute the commands. It just seems weird that out of me, bulletfreak, and omgbossis21, none have been able to unlock.
[LG Optimus L9 P760, P765, P768, P769] elpuertorro:
well just remember the only difference between mine and carlos is that i didn't root until after i unlocked, but pretty much the same remember start from flashing X and U and so on... just to be safe, I know you have done it many, many times but try to do every step and also don't know if I put it on mine but also to be safe while waiting to send command put the screen always on.

Also for some reason this keeps popping in my head do the first one (and hopefully last try for you) with the cable connected while you wait the 1/2hr, and if that one doesn't work try taking cable off while you wait and then insert it and send the unlock command, don't know just try for the hell of it, you have tried just about everything else.. GOOD LUCK!!

If you guys don't take the time to read through everything carefully, you're not gonna understand what you're doing at all and you will skip important steps.

I just sat here and read all 140+ pages, and im rather annoyed

I have the LG Optimus L9 P769 from metro pcs v10b

i flashed the V20B and fought the inversion, i cannot for some reason get radio to work no matter what i do...

and i sat here for 2 hours and tried the OEM-unlock and NOTHING even after 17 tries..lol

I have just unlocked third phone, again on the first attempt. It was warrantied, the board was swapped because of power issues, came back with v20h preinstalled.

Didn't do anything special, just "normal" procedure. Downgraded to 10g, set everything up (APN, visible touches, etc.), flashed Euro 20b, rooted, installed recovery, flashed modem, waited 30+ minutes, first oem-unlock command brought me the unlock screen. As before I did it with WiFi off and StraightTalk SIM in and operational.
[LG Optimus L9 P760, P765, P768, P769] mrmathematica:
Just report my progress so far: first P769, I knew nothing and just followed OP, succeed at third try of 'adb reboot ...'. Not sure why the first two attampt fails, other than I waited two hours (the first two attempt 45 min or so).

Now I get another P769. This time it comes with 20f and has been OTAed to 20h. First time I put Euro 20b on, the LG logo is not inverted. Obviously things are not going to work, but took me a few hours to figure out why. I spend quite some hours to flash back to 10g, and mannually flash ICS x and u. KDZ flash to Euro 20b again. Now the LG logo is inverted. But for my first a few tries today it is not working yet. Not sure why. In both cases I don't have data plan and is on WIFI (the phone call still works with P760 ROM).
[LG Optimus L9 P760, P765, P768, P769] LaDY Vengeance:
So 20f and after is somehow affecting the unlock process? I am tempted to use fastboot now to erase the LG splash before the boot. It's at that point, imo, that fastboot fails to initialize.

If anyone wants to give it a shot, go to fastboot and type this....

fastboot erase splash
[LG Optimus L9 P760, P765, P768, P769] Nathan.7118391:
Nah, isn't it suppose to take over the boot animation? I mean you see the boot and after a second the fastboot comes on, right? The splash comes on after the boot, then cwm, then splash. . .

EDIT: Hmmmmm. . .adb reboot oem-unlock doesn't work

adb reboot fastboot doesn't work

adb reboot recovery gives me a dead android

fastboot is not obtainable with my current build on this phone. When I manipulate it the phone to get fastboot working I can't make

fastboot oem unlock to work

FAILED(remote failure). . .

WTF?!?!:mad::mad::mad:
[LG Optimus L9 P760, P765, P768, P769] LaDY Vengeance:
You may be right about that. Then why would fastboot have a command for splash and a command for boot?

Upon further reading, it seems like you need to have the bootloader unlocked to flash a custom splash1.png. Ugh... back to where we started from.

Unless there is a way to flash a stock 10g splash to avoid the security error.

Okay. I just got finished talking to a friend of mine that is waaaaay smarter than me over the phone.

He agrees with the process in the video and mentioned how I may be using incorrect fastboot drivers. It has nothing to do with the splash....he emailed me a link to download CT_HsPhone_General_Drivers.rar. I'm going to use elpuertorro's steps and use these drivers.
[LG Optimus L9 P760, P765, P768, P769] elpuertorro:
Remember after you install the drivers you have to connect the phone in EVERY MODE for all drivers to install, so connect as mtp wait for drivers to install, then move on to camara and so on wait for drivers to install on each, last one should be LG software mode then to be safe unplug cell then reconnect. Good luck!!

Note: it will give you all the choices in the pull down menu once it's plug in the usb ;)

Do you think that maybe LG sends the unlock tokens based on the production date of the phones?
[LG Optimus L9 P760, P765, P768, P769] leolawliet:

Just reading the original info that LG gives out on unlocking P760 from here:

https://plus.google.com/115049428938715274412/posts/CUu6YE3C6C2

"After installing the JB update, make sure you have a SIM in your phone and let it stay on for at least 30 continuous minutes. This is important!. If you skip this step, you may end up with a permanently locked device.

If everything here is correct, then it implies LG has a way to "permanently lock" a device. Is this why so many of us can't unlock it?
[LG Optimus L9 P760, P765, P768, P769] LaDY Vengeance:
I remember this article. The first time I tried unlocking, I followed everything the video described. I'm sure omgbossis21 followed the steps exactly.

After that, I started mixing and skipping steps. Still no luck. It seems that for some, it unlocks after waiting 30 minutes and for others it takes an hour.

Maybe there is a magic number? You can't wait less than 30 minutes and no more than a certain amount?

If I perma-locked, I will use a hammer to destroy this phone.
[LG Optimus L9 P760, P765, P768, P769] leolawliet:
I don't know how important this might be but for what it's worth my P769 is the prepaid one from T-Mobile, not the contract one.

[LG Optimus L9 P760, P765, P768, P769] leolawliet:
I don't wanna get anyone's hopes down, but is there a possibility they secured the bootloader on the phones that shipped with JB?

Once again, mines came with ICS right out the box. Who was able to unlock with JB right out the box? Please prove my theory wrong.
