its not that hard really, you just gotta get use to the inverted screen, but its not impossible watch CarlosWii5 video and read alot, thats what i did

---------- Post added at 09:58 PM ---------- Previous post was at 09:52 PM ----------

Also i say its worth it to get the Bootloader unlock to get Cyanogenmod, the P769 becomes so sexy with it, better the the T-Mobile ROMS http://www.youtube.com/watch?v=k_4rjsbIzf8
[LG Optimus L9 P760, P765, P768, P769] Corpseet:
Thanks for this. LG symbol is fixed. But after that things are still mirrored but I suspect that is because I have a p760 rom installed.

EDIT: Alright! I just flashed a p769 rom, flashed gapps, and then flashed the touch screen fix......It's fixed! Thank you Wicked2013 and kuma82. I was so close to running it over with my car so I could get a replacement lol.
[LG Optimus L9 P760, P765, P768, P769] LaDY Vengeance:
But the inverted screen can be fixed with that bin file, right?
[LG Optimus L9 P760, P765, P768, P769] Wicked2013:
if u follow the video, get the bootloader unlocked,you then flash your ROM then Gapps then u flash the cwm_ts_fix_p769 zip file then you reboot and your screen will be fine.Everytime you boot into ur phone tho, the LG logo will be inverted but thats ok the touchscreen will be fine

---------- Post added at 10:16 PM ---------- Previous post was at 10:12 PM ----------

uh thats wierd, the LG logo should be inverted, try the fixes again.If u get it right the screen should be fixed but the LG logo will be inverted
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:
okay i got to the screen that says ANDROID 4G T-Mobile.

But its stuck there, it worked for you right? I flashed the exact 10g kdz that you told me to.
[LG Optimus L9 P760, P765, P768, P769] LaDY Vengeance:
Okay... I'll try it out. I'm going to download the necessary files tonight and use my day off tomorrow to flash everything. Your video convinced me, Wicked2013.
[LG Optimus L9 P760, P765, P768, P769] Wicked2013:
my phone also got stuck at that screen what i did was pulled the battery out and power on again, yes the T-Mobile 10G worked for me, when i attempted to unlock i was on the V11A CANADA WIND MOBILE ROM, so when i flashed the european V20B it didnt work, so i then flashed the T-Mobile 10G and followed the video

---------- Post added at 10:29 PM ---------- Previous post was at 10:26 PM ----------

what version are u on right now? i recommend u start from T-Mobile V10G, thats what worked for me
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:
pulled the battery out very briefly then powered it back on, still get stuck on that screen. Do i have to keep the battery out for a certain ammount of time?

Edit: I flashed this from 20f T-Mobile rom. You say dont get the jellybean update and flash it to this from there?
[LG Optimus L9 P760, P765, P768, P769] LaDY Vengeance:
I'm on stock V20F....I have it rooted and debloated.
[LG Optimus L9 P760, P765, P768, P769] Wicked2013:
u should downgrade to V10G, i can remenber where i read V20F might give problems

---------- Post added at 10:37 PM ---------- Previous post was at 10:33 PM ----------

yeah i didnt use Jellybean, i started from V10G which is Ice cream sandwhich, did you phone boot up? when i pulled my battery i waited maybe 10 seconds then i power back on, it might take some time for it to boot up
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:
im going to start from ics now and flash it to this. If this works ill try to find a way to give you 10 thanks:o
[LG Optimus L9 P760, P765, P768, P769] Wicked2013:
V10E and V10G are Ice Cream Sandwhich, V20D is the first Jelly bean update that T-Mobile Pull back real quick cause poepple were having problems with it, and V20F is the second and latest Jelly bean update.Make sure you flash a T-Mobile ROM first
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:
So it's possible to flash it from 10g to another 10g? Sounds crazy but it just may work
[LG Optimus L9 P760, P765, P768, P769] Wicked2013:
no u should not have to do that, they are two V10G KDZs, one from T-Mobile and the other is for ORANGE Mobile(europe) just make sure you are on the T-MOBILE one
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:
so if its already on 10g then i dont need to flash? I was talking about using the one provided by you

Edit: i did a hard reset and i am still on 20f, how do i downgrade?
[LG Optimus L9 P760, P765, P768, P769] Wicked2013:

flash it with the 10C kdz?
[LG Optimus L9 P760, P765, P768, P769] LaDY Vengeance:
I'm going to use fastboot to erase everything and flash the ICS kdz. From there, I just follow the steps in the video, right?

I see that the file used to root says v20b_europe_jellybean_lgp760_ap(11)....that's what is needed while flashing?
[LG Optimus L9 P760, P765, P768, P769] Wicked2013:
thats not a rooting guide, thats the FLASH ANY FACTORY ROM GUIDE, you have to follow it to flash T-Mobile V10G KDZ file
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:
so its basically the video tutorial without the rooting and in Emergency mode? I thought my problem was that i couldn't flash to 10g while in 20f?
[LG Optimus L9 P760, P765, P768, P769] Wicked2013:
u shouldn't have to use fastboot, when you flash the V10G ROM everything will be erase and the phone will boot up like new.First you need the T-Mobile V10G KDZ file, if u dont alreday have it get it form here http://xdaforums.com/showthread.php?t=2107971 .Now that u have the KDZ file we need to flash it, use this guide to flash it, http://xdaforums.com/showthread.php?t=2085344 .Or just watch CarlosWii5 video, hes basically showing u how to do all the steps in the flashing guide.http://www.youtube.com/watch?v=WyNtFP_TkKc&feature=youtu.be
[LG Optimus L9 P760, P765, P768, P769] LaDY Vengeance:
Thanks for helping me. One final question. After I flash ICS, then I flash 20b as shown in the video?
[LG Optimus L9 P760, P765, P768, P769] Wicked2013:
you can flash any rom to any rom, BUT it seams that if u want to unlock you bootloader going from V20F to V20B gives problems.thats why i recommnend flashing to V10G first, THEN flash to V20B

---------- Post added at 11:49 PM ---------- Previous post was at 11:48 PM ----------

yes, thats what i did
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:

there was a usb connection error when flashing to 20B. I should just leave it on for a while unplugged then plug it back in? Because ive had this happen to me before and i think its because the battery can be full
[LG Optimus L9 P760, P765, P768, P769] Wicked2013:
is the on phone on LGSoftware on? ive had a problem before when the battery is 100% charge, let it discharge to less then 100%

My phone is now officially dead. I tried everything, even what [MENTION=4447066]kuma82[/MENTION] said. It doesn't even want to turn on now. :( So, I'm back to the Sensation. I had to pry it off of my cousin. I promised him this cellphone, but now when I get back to New York, I'll send him something else for his trouble. 4 more days left in my vacation, and now I'm just trying to get everything back on the Sensation and keep running as normal. This LG phone has been a very good phone, I only did a few tweaks, to root, and disable QApps, and make the status bar black. It ran with me perfect, and it was modern and stylish. It's a female dog to get it unlocked and having a custom ROM installed. Unfortunately, I will never get to see it actually running on my own. You were good to me phone. Thanks for everyone trying to help me get my phone back to normal, the two tries I have tried to get the bootloader unlocked. Y'all were some troopers.
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:
whenever i try to run the adb reboot oem-unlock command it just reboots. Shouldn't i get a message? Also, when i try to boot into the recovery, it once again wont work. When i open busybox it says something about you have to reroot it because it wasn't rooted correctly. Can someone please help me put a end to this phone crap and unlock it.
[LG Optimus L9 P760, P765, P768, P769] omgbossis21:

[LG Optimus L9 P760, P765, P768, P769] kuma82:
So you took out the battery, and connected to your PC?

And if you did, did it make a sound? Did you install the fastboot drivers twice. Trust me, your phone isn't dead, you just have to play with in the right way to wake it up ;P and I'm not trying to sound dirty ;) make a thread in the help section and I'll help your bring her back to life.

i think i have it. I'm back on 20f for the time being. When i get more time ill try this again. I think i forgot to type in su before the adb reboot oem-unlock command. I hope thats the case, but if it is, wow i messed my change.
[LG Optimus L9 P760, P765, P768, P769] t.d:
Guys, this is actually very easy if you follow the video, just enable "show touches" before you starts. Plug your phone into the windows PC in ever mode ( mtp, lg software, photo bridge) to install all drivers. I had to do some running around since I left my lock on but was able to flash multiple ROMs with an inverted screen and finally got it working. The biggest problem is the screen which scares people , but it you played around with show touch enabled you get used to it after a little practice
[LG Optimus L9 P760, P765, P768, P769] bulletfreak:

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

Phone off , hold vol+ and home press power
[LG Optimus L9 P760, P765, P768, P769] leolawliet:
Yes I'm on ICS and nope will not boot into recovery at all but when I go to software update this is what pops up, it's definitely unlocked, right?
[LG Optimus L9 P760, P765, P768, P769] Lelus:
Yes , looks good.

How did you install the recovery ?
[LG Optimus L9 P760, P765, P768, P769] leolawliet:
Nandroid Manager *ROOT*

I even tried through fastboot, still no luck
[LG Optimus L9 P760, P765, P768, P769] Lelus:
What happens when you try entering recovery?

Maybe after you press power , try holding vol+ and home for a longer time
[LG Optimus L9 P760, P765, P768, P769] leolawliet:
I can't get into recovery that way, so I rebooted from terminal by typing reboot recovery, it's worked on every other one of my devices. Right now I'm on JB, and I'm unable to flash the P760 JB x and u loaders. I guess I'm gonna reflash ICS with Lelus Root method and flash P760 x and u loaders and then attempt to flash CWM from that point.
[LG Optimus L9 P760, P765, P768, P769] Lelus:
Hold on, don't flash anything just yet. Are you rooted and when you turn on your phone is the lg logo mirrored and wrong color ?
[LG Optimus L9 P760, P765, P768, P769] leolawliet:
Nope, I flashed official JB for P769 by the way.

Edit: In the meantime till I can figure out what I'm doing wrong, I'm gonna stay on JB with init.d support and some build.prop tweaks, that should at least improve stuff a bit.
[LG Optimus L9 P760, P765, P768, P769] Lelus:

[LG Optimus L9 P760, P765, P768, P769] Lelus:
I don't think that you bricked your phone with prada files has anything to do with it.

How about LG logo when you turn on your phone, is it mirrored ?
[LG Optimus L9 P760, P765, P768, P769] leolawliet:
Yes I just flashed V20B for P760 and everything is reversed again, I'm about to run LelusRoot and install ICS, but I'm wondering is it better if I try installing the recovery now while I'm still on this firmware?
[LG Optimus L9 P760, P765, P768, P769] Lelus:
make sure "adb reboot oem-unlock" reboots your phone into fastboot mode first
[LG Optimus L9 P760, P765, P768, P769] leolawliet:
Yep :)

Should I flash recovery now?
[LG Optimus L9 P760, P765, P768, P769] Lelus:
yes but flash regular cwm recovery, it'll be easier to navigate with physical buttons

So, after all the pain and agony I have watched everyone go through unlocking this device (with only a few people successful, and then, often with unreproducible steps), and thinking, "this is a GREAT phone from LG, it shouldn't be this hard", I have to sadly admit that I have basically given up and instead purchased one of the fire-sale Nexus 4's that were available from the Google Play store. I basically decided that I had two options: Spend what would no doubt be HOURS and HOURS trying to get this to unlock properly, or just go and buy an even better phone that cost only 20 bucks more than I paid for my L9. Sometimes, you just gotta take the easier path :)

If your reffering to creating a kdz and flashing it with the tool we have no method to create a kdz, only extract. In the firmware thread there is a 20h open for 760?

the 20H cant be unlocked. I dont know what you mean. So we'd need LG's help to get a tool to create a kdz?

In the infobank under stickies it says p760 20h euro open.... if your talking about flashing roms with the LG tool then yes. We would have to be able to create kdz files....
