I haven't kept up on development on this phone for at least 6 months, and have tried a method like this dozens of times before with no unlock in the past, I have the "LG Left Center" (LG logo on the left, T Mobile on the right) model, and I am wondering if this works my model before I go through all the steps of trying again.

Thank you
[LG Optimus L9 P760, P765, P768, P769] kuma82:
I don't know if it will work, every device is different. My tool will just make sure the problem isn't because the system image wasn't installed properly.
[LG Optimus L9 P760, P765, P768, P769] hazik.ahmad:
I don't think I'm really one to say, but this method works the best. I think the syrup most people would need watch is waiting period, make sure you follow those instructions to a T. I unlocked my border a few days back but I had to reset phone using the lg support tool thingy and I just unlocked again today. I was running v21d on a p769 from wind mobile.

Hey kuma. I've been testing your room for about a week and noticed some issues, mainly with the external internal swap. Some apps thst point directly to the internal SD mount point do not work. I was wondering if there was any way to fix this, I noticed that the system lags like crazy when the swap is active. This is on a Metro PCS MS769 with a locked bootloader.

---------- Post added at 08:55 AM ---------- Previous post was at 08:35 AM ----------

Hey kuma it's loopy again. I tried to post on your thread but I'm not at my computer right now yada yada. I am having problems with extreme lag on your ms769 themed ROM. I've narrowed it down to the internal external swap. I would like to see if it's possible to get apps that pull directly from the internal mount point like some system apps and SwiftKey more specifically. It won't save the language file and settings after reboot. I'm also wondering about SD speed boosters and this mod, as I'm not sure if a read ahead will damage things (for example low battery shut down) I'd like to also help others in his. Also wondering where the fix for the LG logo and initial lockscreen after boot fix was.

I've reached the low space error and it seems I'm going to need the swap. I detest this phone for the stupid amount of internal memory, which is why I see an external SD swap is a good idea.

Thanks man.

Your ROM rocks.

LoooyD
[LG Optimus L9 P760, P765, P768, P769] kuma82:
Yeah the whole storage thing sucks. There are several other tricks you can use. The app remount2sd (I think it's called) works well but you have to deactivate it to move apps 2 SD. I came up with a fix for swiftkey and I posted the instructions in another thread. I'll hunt down everything you're asking for later.

Unfortunately for me tonight, I was trying to unlock the bootloader and I may have really messed up. I used the script and everything was fine besides it being inverted so I kept following the instructions till now where I'm getting the "Security Error" screen, it shows up for about 30 seconds and then gives me the black screen. I have been searching everywhere to try a fix for this but to no avail. Its a Metro ms769 and I had 10E on it, went to 20b and now I have the error. Can anyone help? Basically I would like someone to point me in the right direction to where I can get back in CWM. Vol +-, power, and menu keys do not have any effect on the symptoms.

The system image (or boot image) got corrupt while performing the offline flash. These two threads will help you out.

http://xdaforums.com/showthread.php?p=43703749

http://xdaforums.com/showthread.php?p=48834061

You need to perform the offline flash by putting your phone in s/w upgrade mode. Hold vol button up (phone off) and plug in the USB cable.

However, you need to use fastboot first, because the offline flash doesn't work properly on jellybeans x or u images.

So you use fastboot to flash P769 ice cream X & U (x-loader & u-boot) so the offline flash tool will work.

Update:

I would first try replacing the boot image with fastboot before performing the offline flash. It may save you sometime. However you will need the boot image that matches the system image.

:) great! well since you said that. what rom were you on before flashing v20b, ics or jellybean? also after you flash v20b, did you remove the modified lg address that you put on the host file to stop the updater from updating or did you still leave them on there?
[LG Optimus L9 P760, P765, P768, P769] sigion:
JB. if I remember right it was polish v20c. In host file I didn't have any anti-update modification because I used modified package called

Original topic

http://d-h.st/hed

So consider this as no modification in host file after flashing v20b.
[LG Optimus L9 P760, P765, P768, P769] ThEuNdYiNg1:
did you follow these exact steps or did you skip some?

1. Perform the offline flash of Euro 20B kdz.

For *769 models

(To make things go smoother, disable pattern/pin lock screen, start off on any jellybean kdz, and enable show touches.)

2. Open Start.cmd (double click), and root with cydia impactor. (USB debugging should still be enabled)

3. Select yes to replace the system image, and wait a very long time (approximately 13 mins).

4. Reboot phone (must reboot) and root again with Cydia.

5. Skip install of system, push flashable files to External or Internal SD (only for *769 models), install busybox and recovery.

6. Reboot phone and flash radio zip (for *769 models only) if needed. Actually this step can be performed before flashing the system.

7. Play with the phone for about 45mins. Turn on data, open a browser, turn Wi-Fi on for about 10 mins. Don't rush this step.

8. Run the script to the very end (skip system flash & pushing cwm files), and select the reboot option to unlock bootloader.

on most of the unlock methods it says not to reboot phone, but here it says to reboot on step 4

I usually use opera classic for downloads, and as for the mega website, I don't like their mobile app, so what I do is, when it asks if you have the mega app just click cancel and then hit the menu button and then click "request desktop site" and the mega site will then load and allow you to download the file without any problems and usually pretty quick.

You know it's never to late to learn. I just got started last year. Don't get me wrong, I do know a lot about computers but I wasn't quite familiar with Android. I did a lot of googling and learned quite a bit by dissecting other people's work.

Guys... I was kinda sad because ran into the issue that the phone rebooted to a black screen. After pulling the battery and powering it up, it'd boot to CWM Recovery.

Well.. i could unlock it!! while I was in CWM Recovery Mode, i noticed the ADB interface was up.

issued the command manually (adm reboot oem-unlock) and voila!! got into the inverted "Unlock", Push Volume Up screen.

I've confirmed i'm unlocked because i installed CM11 and it's working flawlessly.

[MENTION=4447066]kuma82[/MENTION]

Wow I've must've have been tired when I read that post. I would give it a shot. Hopefully what worked for this guy works for everyone. It makes sense. The recovery (2nd-init cwm) uses the stock kernel but it doesn't use stock adb (it uses cwm).

This maybe the new way to unlock. I've heard of several people booting into a blank screen (after issuing unlock command) that doesn't respond to any commands.

[LG Optimus L9 P760, P765, P768, P769] chlhec:
Flashed it, i'm back to normal (LG logo as it should be, no wonky/inverted screen at all).

Thanks UltraRoboto for the heads up.

What I did was, follow [MENTION=4447066]kuma82[/MENTION] 's script all the way to the last step (flash system.img), push flashables, play with the phone ~1hr or so. everything... right on the last step when i tried to reboot & unlock the bootloader the phone screen would just go black. (That's what some of the people get).

You can press the powerbutton to force a poweroff (~10 secs??) or pull the battery.

When you poweron the phone it'd boot straight to CWM.

When on CWM don't do anything, just hook the phone to the PC, you should have the ADB interface in device manager.

use the tools folder in Kuma's zip package, and issue "adb devices" to confirm your phone is detected.

after that i just did "adb reboot oem-unlock" and the phone's screen got like a DOS screen (black background, white letters). Try to read (or use a mirror) to confirm it's the "unlock" screen. Press the Volume+ button, the screen should change to something about fastboot. I just powered the phone off again (as the instructions stated on that screen) pressing the powerbutton for ~10 secs. Upon reboot I was unlocked. :)

Didn't work

For those of you on the edge of your seats, running adb devices oem-unlock while in CWM recovery mode(entered via bootloader unlocking tool) didn't work. I just got a normal boot. However, I did not get the black screen as mentioned above. Maybe that has something to do with it. Also, when choosing to unlock the bootloader via kum82's tool, I got a message saying "rm failed for /data/local/tmp/u-check.sha1, No such file or directory" maybe this has something to do with this. I also get "adb server is out of date killing..." And the tool tells me to have a signal. I'm not sure whether this is a phone signal or a wifi signal.

No because the system looks for "c:\windows\system32\drivers\etc\hosts" and not "c:\windows\system32\drivers\etc\hosts.txt".

It's possible that the hosts file is flagged as "ReadOnly", which would prevent you from saving any changes to it or overwriting it. Also make sure that you or your account is the owner of the "c:\windows\system32\drivers\etc" folder. You could also temporarily disable UAC settings.
