Check out twrp. Way better then cwm. Cwm may be the problem

You probably still have system still mounted. Use adb in recovery and type

adb shell
umount /system

then try to format system

I'm starting to wonder this too. At this point I've read and tried just about everything mentioned in various posts, and no unlock. I got it from Best Buy last week and updated to 20D before trying to unlock it, and went from that to 20B euro on the first attempt.

Back to trying again tomorrow.

Woooooooooooooo

big thanks to everyone helping out in this thread. finally got my p769 unlocked

Some problems that I encountered & fixed, going from v20f rooted -> 10g unrooted -> v20b unrooted -> v20b rooted -> CM 10.1

- during offline flashing, if you get to 15% and it tells you your phone isnt connected and you have to reconnect, then use fastboot to flash ics xloader & uboot (everytime I flashed JB onto my device, I had to use fastboot)

--- if you're using fastboot and your device is not detected, then you havent properly install the OMAP drivers in 2 places

- during offline flashing, if you get something along the lines of a "fatal error" your kdz may be corrupt (i had to redownload)

- if you can't get the recovery to install (some "exec" error), then you haven't rooted properly

--- if you flash v20b and you're not rooted afterwards (like me), you can root by using the LGPwn.apk

------ if LGPwn.apk doesn't root,

- if you can't reboot into recovery, make sure you have the correct version of busy box. Then reinstall the recovery

- if you're trying to unlock with adb, and it only results in a reboot:

--- make sure you have a signal during the waiting period

------ if you flash the radio.zip and still get no signal, make sure the sim card is in the phone (not necessarily activated)

--- wait for at least 1 hour after boot, with a valid signal

--- make sure your phone is in "LG software mode" when you send the adb unlock command

------ if you can't get into "LG software mode", replug your phone into a usb 2.0 port (not usb 3.0)

Please Help

I swear that I followed these exact steps perfectly (and began in the same state) but I am now unable to get step 7 to work and I have identified the following things about where my p769 is right now:

Currently on 20b EU Open

active sim has been seated in place throughout

Completely inverted (all splash/boot/ROM/colors)

USB Debugging is enabled (icon in status), but in Dev Options it shows checked but greyed out

PC Connection mode: LG Software

Signal was weak on edge (2g) but consistent for well over 4 hours (I paused to sleep during that time)

adb commands function without errors

`adb reboot oem-unlock` reboots back to the ROM no fastboot screen

`adb shell su` returns: "/system/bin/sh: su: not found"

I have a few questions:

In step 1 you state: "Download and extract x and u to sdcard." I used the p1jb769.bin & p2jb769.bin from [MENTION=4447066]kuma82[/MENTION] (cant find the fastboot.zip post). Where are "x & u" that you used from? Can you post a link?

What should I do now? :confused:

I really don't think 'x & u' are an issue here because from my understanding those were to allow for offline flashing of kdz files and I had successfully offline flashed 20b in step 6 (above)

I'm pretty frustrated because I had originally watched [MENTION=4730658]carloswii5[/MENTION]'s youtube video all the way through before then attempting to do the actual steps for real and ended up with a 20b that was in no state to oem-unlock. I later found this set of instructions and got everything prepared and ready before going through all of them. All-in-all, I've spent the weekend and 20+ some sleepless hours only to be stuck in an unknown place. :crying:

I'm truly grateful to all of you who have converted your own frustrations with this freakin' bootloader from hell into useful instructional posts for the entire community to build from. The root of my frustration comes from meticulous preparation and jumping through well over 6 separate threads here only to come up short.

Could someone please help me proceed from here?

Thanks.

So I followed this and it doesn't work. It goes okay until 5% when it goes into Software upgrade. I set it to SP3 for Windows XP, and put it as admin. I have Windows 8, I assume that is the reason why it is not working. I have tried several times to no avail. Please help?

Amazing as that was so little information and focussed on the P760 variant. I'm going to offline flash 10G again and then begin the ol' ICS unlocking process here.

This may be my final attempt as I return to work tomorrow and will have zero time available to work on my Daughter's phone. It's funny to think that this all began when she was unable to install the SIMs game without app2sd enabled :p

I'll report back after. Thanks again!

Well, spent all day today trying to get this to work and nothing came of it. Tried the newer method as well and all I have to show for it is a 10g phone, previously 20d, with an inverted screen.

Shttp is in your c drive, correct? Not in subdirectory. You need to be able to flash on and off line so you might want to familiarize with that procedure, as well as rooting that way.
[LG Optimus L9 P760, P765, P768, P769] erraggy:
towel. thrown.

Well I tried. Same exact outcome. adb reboot oem-unlock fails to unlock the bootloader and lands me back to the ROM upon reboot.

If I offline flash 20d, will I end up with mirrored display and wonky touch-screen? I'm going to try that now, but if any of y'all know the answer and have a remedy to get this device back to stock jelly bean for tmous, please chime in.

peace.
[LG Optimus L9 P760, P765, P768, P769] greencartim:
Yes it is in the C drive, it won't install the mobile support tool and flash the kdz file. Once I can flash the kdz file and wait the 30-60 mins I be good to go, right?
[LG Optimus L9 P760, P765, P768, P769] kuma82:
Yes you will. Just restore someone's 20f cwm backup, fix touchscreen with lelus zip, and fix the inverted lg logo (20b u-boot) with my flashable 20f zip.

And I actually have a CWM backup that I made of my daughter's phone previous to any of this. I had thought that CM10.1 was possible without unlocking the bootloader and only had completed the [MENTION=2159458]Lelus[/MENTION] L9 root and then installed CWM Recovery via the LG Recovery app.

Searching now (with no luck) on finding how I can get CWM installed or flashed.

Inverted LG

Hey I was thinking about unlocking my bootloader but I don't like the inverted LG. If I were to unlock the bootloader and flash my v20f again will that correct the invert?
[LG Optimus L9 P760, P765, P768, P769] The Bouncer:
I've been stuck with a inverted screen and messed up touch screen for the past two weeks because I can't get this to work. I've tried 20B Europe and a p65 Indian 20A but all I get is a reboot on the command. I've watched the video, read thru multiple threads and after all this time I still haven't gotten it unlocked. I instaledl omap4all, I've tried lelus script but still the only way I can boot into fastboot on the phone.
[LG Optimus L9 P760, P765, P768, P769] Nathan.7118391:
When you flashed the v20b did you have signal? You have to flash your radio or it will not work. I'm guessing you have tried flashing your original ROM which would be the v20a right? Have you tried a factory reset? Maybe you should install omap4boot and fastboot again just like you did before then try the command. I have been thinking about troubleshooting problems before I get into the situation so these are some of the resolutions I came up with while brainstorming. Also I would try to do the procedure again but this time flash you my original stock ROM and start over. Oh yeah and you have to re-install the drivers after you flash v20b.
[LG Optimus L9 P760, P765, P768, P769] DJ Scooby Doo:
So, I got up to waiting the half hour or so to do adb reboot oem-unlock, however I have one question. Do I still have to flash the radio.zip if I have signal already? It seems unnecessary to do so, following the video.
[LG Optimus L9 P760, P765, P768, P769] Meda808:

[LG Optimus L9 P760, P765, P768, P769] DJ Scooby Doo:
Wasn't all that easy to be honest. I had to do a mix of steps to get my phone working. For starters it was downloading the latest V20F, update then injecting the 11 bin inside while the phone was updating (just like you did with 20B). Hopefully you have the CWM installed, but if you didn't, install the app and the recovery. Then flash the zip a few posts up. It took me a while to get this all set up. Trial and error. But now I'm up and running like before.

V20F: https://mega.co.nz/#!zMtijS4C!FUQuC01hnmKc72cyNMuCvD4A1HIeX3MYyZPZSh3t4aI

[LG Optimus L9 P760, P765, P768, P769] Meda808:
So you have inverted blue LG logo.. congrats on unlocking your bootloader. Will the phone boot up with an inverted screen? If so, then you need to install root, busybox, artas182x recovery.. then you will be able to flash a rom, apply the touch fix, apply 20f uboot fix, and you're good to go.

After two weeks of trying the command and workiing with the screen Ive decided I'm just gonna give up. I got back to 20f and fixed the touch. The phone just wont boot into fastboot after the command. As a matter of fact the only way I can get fastboot on the phone period is to hook it up to the pc and run lelus scrip or omap4all. But even then it is inverted and you can only send commands to from the PC while the phone is connected. And even then after about 3 min it just reboots without me even doing anything.

This is too much to just to be able to put roms on a phone... Never again will i get another LG phone!!
[LG Optimus L9 P760, P765, P768, P769] kuma82:
You don't get the official fastboot until you unlock bl(plus you need to be on an unlockable Rom or custom rom), that inverted one is the unofficial fastboot. I'm glad this is my first real phone, I didn't know other devices had it so easy. However, it is really hard to hardbrick an LG phone ;)

I'm also wondering if flashing the open firmware then booting into its built in recovery will help. I however can confirm that from 20f if you flash the 20b u image and cwm recovery then reboot recovery you get a inverted lg secueity error. Then flash x and u from ics so it recognises it and flash open firmware. This does it right (fully inverted start to end) like it should be.

[LG Optimus L9 P760, P765, P768, P769] omgbossis21:
You can run the 20b boot image on 20f but you gotta fix inverted. It wont help though, I've spent days messing like that. Heres something interesting.... In order to do the unlocking process it has to check the sim right? Well whats its looking for is that the gsm.operator.numeric is 00101 which is a generic operator value for "test". I think we should pull a 20b build.prop and change the gsm.operator.numeric value to 00101. If it doesn't work its one more thing we've done to bring us closer to what it wants to see......
