Where I am at: Phone was previously rooted. Followed video to the point of issuing unlock command through windows. Waited 45 minutes with cell service, issued command, phone rebooted without fastboot. I am now on my linux laptop trying to adb oem-unlock, as some said they had better luck with that. Plugged in, waited, I did it, phone rebooted without entering the fastboot. I enabled Wifi, let phone sit for 45 minutes, sent unlock, and the phone just went black, didn't immediately reboot as before. I finally was able to wake it up, but it was completely wiped and back to factory (but still reversed). I then configured the phone (no sleep, usb debugging, wifi, show touch) and waited another 45 minutes, sent unlock command, and this time the phone blacked out, 30 seconds later showed battery logo.

I searched the forums, the only other person who mentioned the charging logo that i could find had apparently unlocked previously? At no point was i ever able to issue the unlock command and have the phone boot into fastboot.

Any help from here would be appreciated, I'd imagine I need to just start the whole process over, but I am not even sure how to go about that.

[LG Optimus L9 P760, P765, P768, P769] bolognatrombone:
yeah, at this point I pretty much would like to just go back to stock and pretend this never happened. Stock is hideous, but at least it's not reversed :)

what rooted verison u had before attepting to unlock bootloader? i had the same problem u had where after sending the oem-unlock code the phone would just reboot normaly.I was using the Wind jelly bean ROM and i was rooted as well, what i did was go back to stock T-Mobile V10G, once i was back to stock i went to V20B, root and i got it unlock in my first try, also the SIM that i used was a Solavei SIM that i have no service or data on it, i havent paid it in months since its prepaid

i followed CarlosWii video and it worked for me, try going back to stock V10G, once there follow the video, thats all i did and it worked for me, i didnt think it was gonna work for me since my SIM card has no service or data but it worked, i left my phone on for 45 minutes, oh and i didnt use that lgpwn.apk, maybe thats messing u up

i unlocked mine yesterday, i was on the Wind (Canada) ROM and rooted, cant remenber which version it was, and flashed the european V20B kdz, after i did my screen was reverse.I kept folliwing the video, i got stuck where you input the "oem-unlock" command, it would reboot but it reboot normally instead of taking me to the unloack screen.So what i did was go back to T-mobile V10G stock, one thing i did before flashing V20B and rooting it again was disable Lookout Security android antivirus, i dont know if Lookout is give yall problems.Ok so i flash and root V20B then kept following the the video and got it unlocked, and now im on CM10.2 UNOFFICIAL for p769 [08/30/2013], its pretty nice

Lets try and get more responses this time.

How many people were able to unlock the phone, with the t-mobile variant?
[LG Optimus L9 P760, P765, P768, P769] omgbossis21:
With an activated sim card and were sure your phone was sim locked at the time?
[LG Optimus L9 P760, P765, P768, P769] MoonMaster345:
Well the phone is brand new from t-mobile so yes the sim is activated, working 4g and everything.

i never lost radio during the flashing though which i found odd
[LG Optimus L9 P760, P765, P768, P769] Wicked2013:
i did, started from V10G

check this out, my SIM card is a Solavei SIM, Solavei is a MVNO that uses T-Mobiles network, its prepaid.I actually dont have service or data in the SIM cause i havent paid my account in months, but i have signal.And it worked, yes my phone is locked to T-Mobile

---------- Post added at 05:31 PM ---------- Previous post was at 05:18 PM ----------

heres my theory, since you didnt lose radio something is not right, our phones(T-Mobile) are P769, when you flash the european V20B kdz you should lose radio since now your phone now has the P760 firmware.The P760 variant is different including the screen, thats why when we flash that version our screens gets messed up.Since you said ur phone is brand new it mayhave the latest V20F version, i would recomed form my experience to downgrade to V10G then start the unlocking method.
[LG Optimus L9 P760, P765, P768, P769] isaacj87:
I have a P769, and when I flashed the the 20B KDZ, I didn't lose radio. My baseband version changed (it downgraded), but technically I didn't need to flash any radio fix. (I did, however, just to be sure). I was still able to unlock my bootloader.
[LG Optimus L9 P760, P765, P768, P769] Wicked2013:
oh ok i guess i was wrong
[LG Optimus L9 P760, P765, P768, P769] omgbossis21:
Last time I flashed back to 20d kdz from 20b the baseband or radio remained the same showing hspa instead of 4g and actually gets 3g. On 20b I get no service at all but now with whichever didn't get replaced I get better signal. We Can set the carrier region manually to see if it even takes on whatever firmware.
[LG Optimus L9 P760, P765, P768, P769] t.d:
help

So I tried doing this last night, accidentally left my lockscreen on, and can't get recovery installed on 20B. I started on 10g > 20b > 20f >10g >20b. Root isn't working from 10g to 20b. I have everything working as far as flashing goes, but rooting is a problem. Please help!

Right now Im on 10g, no root, with an inverted touch screen :(
[LG Optimus L9 P760, P765, P768, P769] Wicked2013:
when i unlocked my Bootloader i started from V10G with a inverted screen,so i checked USB debugging on, then disable Lookout Security App plug my phone to computer and starting flashing V20B, while you flashing it u are also gonna root it using the LGP760_AP[11] root bin file, after flashing is done ur still gonna have inverted screen.Then istall the recovery, then the radio fix after that leave your phone on for more then 30 minutes then do the oem-unlock command, it should reboot to the bootloader unlocking screen
[LG Optimus L9 P760, P765, P768, P769] t.d:
Thanks, Im just going to try disabling the security. Googling now, unless you have a step by step.

I can get to the lelus app in 20B, but it didn't install recovery. Im thiking it never took root.

edit

On 10G I stopped and disabled security in the "running" apps list, ran lelus jb script, flashed with #11 bin file in place, while on 20B lelus still wouldnt install recovery which was in my app drawer :( Ima pull my hair out when I go back to 10g inverted touch screen for something small :(

I have touch enabled but when I go back to 10G I have to hard reset :( :(

I also have a newer driver version, would that be the problem?

As of now Im leaving my brick on 20B, not root, no recovery untill someone speaks up.
[LG Optimus L9 P760, P765, P768, P769] Wicked2013:
the way i disable it was i went to settings, apps, then all then i had to scroll down to find it then click on it then disable it, i know its kinda hard because you have to do it with a inverted screen, i know how frustrating it can be but its not impossible, if you dont have the "Super Su" app in your phone ur not rooted, thats how u know have root or not

---------- Post added at 11:21 PM ---------- Previous post was at 11:16 PM ----------

after you flashed 20B do u have the Super Su app in ur phone?

[LG Optimus L9 P760, P765, P768, P769] Wicked2013:
hmm interesting, i think i did it a bit different, after flashing 20B i had to install a recovery, but it wasnt CWM, it was Artas182x's recovey.His recovey has the LG logo on it, go http://youtu.be/WyNtFP_TkKc?t=13m36s ,thats Artas recovery not CWM, i did flashed CWM but AFTER bootloader was unloacked

AWESOME, I have an older version of cm10.1 running. Things are running great except that my radio is not working like it did before all this. Is there a list of radio versions I can flash now that it has CWM and is BL unlocked?

[LG Optimus L9 P760, P765, P768, P769] MoonMaster345:
Congratulations mate.

Anyways, can we startup a discussion about making a 2nd init rom?

if you want i can make another thread. Ive been looking up the term on google and for the life of me i can't find a tutorial or something for building a 2nd init rom.

Should the term be Dual Booting?

Because it'd be great for us stuck in bootloader limbo.

on a side note. ANY Metro PCS users around there? if so, can you give a call to metro and LG about getting a bootloader unlock?

i think if we can crack on variant, or clone, we can crack the other.

or you know.. reverse engineering the p769
[LG Optimus L9 P760, P765, P768, P769] DJ Scooby Doo:
Aight, I'm going to get on it. Good looking out for the info!
[LG Optimus L9 P760, P765, P768, P769] LaDY Vengeance:
Yes, yes, yes.... the P769 needs a 2nd init thread!!!!
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:
So with a 2nd init rom im assuming it installs like a dual boot would? How would that fix the problem with most of us not being able to unlock the bootloader? (noob question). Also, would LG give out such software if it existed?
[LG Optimus L9 P760, P765, P768, P769] kuma82:
A 2nd init is just using the stock kernel, so the system will still be 4.1.2 jellybean. The only thing that is changed is the ram disk, so we can basically do away with the crappy internal storage problem.
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:
Sounds viable but id really brother get a custom kernel for overclocking and extensive customization
[LG Optimus L9 P760, P765, P768, P769] omgbossis21:
We can implement the oc scripts into the 2nd int rom :D. 2nd into roms mostly just lack kernel changes but as normal with going from stock to unstock roms its night and day. Its not just for those who have been unable to unlock, some are to Leary of the process and others wanna keep with the warranty :)
[LG Optimus L9 P760, P765, P768, P769] kuma82:
Overclocking is currently available on stock, but yeah I see what your saying.
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:
Yes but i personally dont know how i feel about having my whole rom stored in ram. One of the big things about custom roms are the kernels. The only other main thing i can think of is the lack of a built in themeing engine, which is available if your rooted from here: http://xdaforums.com/showthread.php?t=2240180

But i guess if you really want to go at it
[LG Optimus L9 P760, P765, P768, P769] omgbossis21:
Don't believe its stored in your ram but I'm not entirely certain with 2nd int. Pretty sure it has its system partition like anything else. They definitely can still be themed.

Edit. I have ran 2nd int roms and the cm theme choosers worked just fine pending the dpi is set correctly :)
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:
thats not what i was trying to say. I just dont want all of the focus to go on a 2nd init rom. I just really want this bootloader unlocked
[LG Optimus L9 P760, P765, P768, P769] omgbossis21:
I just want cm10 until I can unlock the bootloader lol. A failed unlock attempt restoring a 2int cm10 won't feel as bad lol.
[LG Optimus L9 P760, P765, P768, P769] bolognatrombone:
Can anyone direct me to instructions how to return this phone as close to stock as possible? I'm currently inverted and just want to be able to use it, can't find links for v10g or any instructions.
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:
Your going to have to do a hard reset, then update the recovery back to normal with the LG Mobile Support Tool (be sure to remove the two added lines of text in the hosts file or it wont work.) And finally fix the inverted screen

with this: http://xdaforums.com/showpost.php?p=40121966&postcount=7

Ignore the 2nd step if you dont want a headache. Just download the LGpwn.apk and root it that way (although it is kind of hard to with the inverted screen, it's still very possible.) Then just do step 3 and it should be fixed. I know this still requires it to be rooted and to do a hard reset, but that's the closet that i've got.

:cool:

Alright, yesterday I followed this guide. After I unlocked the bootloader I rebooted into recovery, I followed everything in the video, wiped the cache, formatted the system, etc. I installed my rom, avatar, but I didn't flash the touch fix before I rebooted. So when I arrived on the home screen of course everything was still messed up. I tried adb reboot recovery but I was presented with the device not found error. I unplugged the usb and then plugged it back in, I noticed in the status bar it said connected as a media device. After fighting with the screen I found myself in settings to look for pc connection and to my surprise I did not find it. This my first time using avatar or any rom for that matter. I also cannot find developer options to turn usb debugging on. I tried reinstalling the drivers on my pc but I still wasn't able to use adb or the LGMobile support tool. After that I restored my pc to factory default, I installed the drivers again and I still cannot use adb, I'm sure I just need to enable usb debugging and set then pc connection to LG Software but as I stated before I cannot find where they are located in the settings. At this point I have no idea what to do, I don't have a backup either. Any and all help is appreciated.
[LG Optimus L9 P760, P765, P768, P769] Wicked2013:

When flashing 20B i can boot into the stock rom, but when trying to boot into the recovery it doesnt work no matter what. So is there any other one that should work?

the uropean version shouldnt do that, the adroind bot shooting up and stuff is T-Mobiles boot up screen when you have a T-Mobile ROM, whn you flash the EUROPEAN V20B you only get the LG log boot up screen cause its not a T-Mobile ROM

Thank you, I was able to get into recovery. I wiped everything again and this time flashed cyanogenmod then I flashed the touch fix. I rebooted and when I arrived on the home screen it was still mirrored but the touch was a lot better, if I want to choose something I have to press the opposite side of the screen. I'm sure I screwed up but help is still appreciated. I was able to get into the developer settings just like you said too. I'm still not sure how to set the usb to LGSoftware because I cannot find pc connection. If it is in developer options forgive me, my eyes are bad enough looking at regular text. Sorry for making you spoon feed me.

EDIT: I plugged it back in and when I saw connected as a media device pop up in the status bar I pulled it down, I dropped down USB computer connection. Under this is a connect as sub-section and there are only two options, Media Device (MTP) and Camera (PTP). There is no LGSoftware, also when I choose camera windows tries to install the drivers but always fails, I am able to use it as a camera though.
