Hello i have just purchased this phone and i want to unlock the bootloader and install CWM and then Cyanogenmod but im finding it is very difficult to do so.. I have a few questions.. i have found some info on here but it says from tmobile 10g..which i am not.http://forum.xda-developers.com/showthread.php?t=2277639. Why is it so hard to do this and why after so much time has an easy fast method not been posted anywhere.It pisses me off they lock this thing up with all this built in bloat and make this so hard for users.. we are paying for the phones-therefore we should have 100 percent control over how they are used..
1. Is there any easier less risky way to unlock my bootloader and install cwm/cyanogenmod than this clusterfack way
(http://forum.xda-developers.com/showthread.php?t=2277639) for noobs ha
2. I rooted and flashed Cwm but i cannot get into it either with key combo or adb reboot recovery(brings me to android with open stomach screen, thats it..and i assume if i try to flash a zip like cyanogenmod IF I DID GET IN WITH A LOCKED bootloader it wouldnt work or id get security error)
i have busybox installed and phone is fully rooted..I need to avoid bricking and security errors at all costs
3.i need detailed step by step instructions for lg l9 p769 21d (locked bootloader) willing to offer a bit of cash to anyone who can help me successfully Unlock my Bootloader without any device brickage or security errors.
Update: Itried installing the artas test version on cwm with his installer and I now can get into cwm..the stable one wasn'tworking..
So now Ihave recovery just bbootloader locked preventing me from flashing any new ROMs...sighh
Update..I used cwm recovery installer by artas and I now can get into cwm
Device info
lg l9 p769 21d (android 4.1.2)
build number JZO54K
1.) Flash to 10G. T-Mobile doesn't matter, it still works with Wind. I've used Wind ROMs on my T-Mobile.
2.) That is the only way to unlock it, I'm sorry. Some conspiratist was trying to unlock it using a different method, but he rage quit when someone made fun of his website (lol).
3.) Really, it just takes luck. I haven't got it yet. But I try daily and it takes about 20 mins of work and 30-40 mins of waiting, so it's worth it. About to give up though lol.
LOL, I just realized you used numbers too. My numbers here don't correspond to your questions in that order. What a coincidence!

OK flash from 21d wind too T-Mobile 10g... Then I need to flash to Europe open 20b for 760...unlock the boot loader with mirrored image and messed up touch screen..then gain root..install cwm and fix the touch screen..
ARE YOU SURE I CANT GO FROM 21d to EUROPE 20b? Unlock bootloader and root and then Be done with it?And if so , Why not?
Anyone here unlocked boot loader of 769? BTW there is no working link to Europe open 20b kdz..I've been looking everywhere for an hour all links and downloads are broken/not working..anyone have the Europe open 20b for this process?
edit think i found the europe 20b
People say there's problems with it lol.. I haven't unlocked yet sadly. It's an annoying process and I feel that some devices can't be unlocked no matter what

Well it can be unlocked..but its a pain..day 1 and lg support tool will not install w admin priv/compatibility mode for xp sp 2/3.I'm on win 7
I take it this is why it won't flash the kdz and crashes the kdz installer..also shows phone not found in emergency mode but it is found in diag mode..what's with that?
Lol.. I'll try again tomorrow.. But I think I need to on a diff PC cause I've tried everything and it just gets stuck(lg support tool) at like 10 percent install..
What is the reason for going from 10g to 20b Europe and then back to 10g
Why not just stay on 20b fix the touchscreen etc and leave it..?
What issues if any would arise from flashing 20b Europe from 21d wind?
The unlock boot loader for.noobs 769 has files for SD including radio.zip..
Does the radio not work after flashing 20b Europe open? And if so how can I flash a zip on Europe 20b and unlock the boot loader without first installing radio.zip through a cwm?

Go to the General section, and find the sticky (at the top) of the thread with the stock KDZ's by cmahendra. Find the ICS KDZ for P769, and download it.

Same here man i had unlocked the bootloader a while back before the JB upgrade was gonna try a Rom so decide to flash recovery and got the Sec error did all reflashed KDZ back on JB rooted and with artas recovery they say once you unlock the bootlader it stays that way, anyways did all the steps again to unlock, but boot normal and i have no way of checking... How can we know or check that the bootloader is unlocked??
Anyone????
If you have unlocked your bootloader, you would know
anyways here are a couple of ways to check, because y'all still want to check
1. Dial the number EVIL#*769# (3845#*769#) this will get you into the hidden menu
note: if you have a P760 change number to 3845#*760# change the last number/digit to whatever your device is
Once in that menu look for the bootloader tab, if it doesn't have it, sorry the kdz you are on doesn't show if it's unlocked or not.
2. Put your phone in the s/w upgrade mode, it should show unlocked bootloader
3. Another way to check is to fastboot and flash a custom recovery for your device BUT first extract your current recovery.img in case you receive a security error. However, I would advice y'all don't fastboot and flash anything unless you really know what y'all are doing. You have been warned!!!

In your case @elpuertorro you have to flash the u-boot.img from a P760 v20B
I uploaded the u-boot here http://forum.xda-developers.com/showpost.php?p=43386521&postcount=14
Another thing, if you did in deed unlock your bootloader, flashing a new kdz will (should not) not replace the u-boot.img. All P769 or LGMS769 will know right away if their bootloader is unlocked because the "LG" letters will be inverted when your boot up the phone (unless you flashed a u-boot.img from a P769).
Thanks! This are my unfortunate results.
I did not see the menu. I did the offline flash of V20_00
Nothing about unlocked bootloader
Yeah... I don't feel confident enough to try this again. Not yet.
Oh well. I'll wait longer until I feel better about what I am trying.
I have the P769BKGO GSM unlocked using Net10. So I think I won't be able to do the adb reboot oem-unlock trick. Other thoughts? Is flashing a different KDZ the only other route?

Thanks kuma the thing is i did this when i got the phone back in Jan so as you can see by now what ever i did is a bit of a blur, (short time mem loss you know lol) but i did recall doing it and have my folder set up for my phone, but to try to remember what or how and what tut i followed is the problem...but it's cool because i was looking for
V20b and since i could find one yesterday talking to carloswii for a copy asked if V20c would work as he didn't know figured i will try it and report back for the benefit of all....so that's next today
ps Kuma that's great advice but hey @thchipmunk don't be scared man is scary reading all but once you do it like 2 times it's all smooth plus with th KDZ offline method this cel comes back to life in no time so far as they have said you can't brick this phone even if you tried lol. to the rest stick with kuma's advice lol.
I am mostly just scared because it took me forever to get the KDZ to flash again. I kept getting that the USB was not connected to the phone so I wasn't able to ever complete the flash.
I do wonder though, if I would be able to unlock the bootloader. I see the directions say you need to wait 30+ minutes once connected, I assume this is some restriction in place on the actual phone with the SIM. However, I have an ATT SIM that I am using through NET10. Will that matter?

Been there , done that lol
By anychance when that happened to you
1 you were connecting the phone on lg software mode? that's what it should be and i'm sure you was
2 if you did, was it giving you errors about installing drivers failed?? that happens to me sometimes so i just restart the pc and then the phone get's recognized.
just remember sometimes we have to hit that skip that pops up when it's searching for drivers on the phone.... worse comes to worse reinstall the drivers for the phone hope this helps you out man.
Okay, so I restored animusFL's deodexed stock backup, and then I flashed the CWM recovery V20F update, but now my phone is stuck at the T-Mobile logo, and even if I try to flash a KDZ with S/W upgrade mode it doesn't work because I was previously on JB. I'm unable to access my homescreen to activate LG Software Mode. Can somebody please provide me with a simple hotfix? Please I need this fixed before night lol.
EDIT: I'm unable to access my Locked Bootloader CWM as well, before the flash I selected to preserve root and recovery but it didn't work... So now I have a phone that says T-Mobile constantly. /:

Hey llxaot, I'd be interested to know if you tried Kuma82's suggestion & if it worked. I'm in a similar boat ... working phone, but locked bootloader and not rooted on P769 with v20f OTA.
Kuma82, my phone is fully functional now. I'm "simply" trying to unlock bootloader & root the device. The methods in the links look to restore function of a device that's been soft-bricked, etc.
Is this the only currently known method for unlocking bootloader on P769 v20f?
Basically get fastboot working via Lelus script, flash the uboot and xloader from the 3rd link in that post & I'll be unlocked & have ICS recovery on device?
Then, I just need to flash back JB, flash CWM recovery (if I want) and root?
SO DAMN CONFUSING...this is by far the most difficult phone I've ever worked with.

I fixed it with Lelus' help. Kuma's would definitely work but I can't seem to get fastboot to work. Anyways, what I did was went into LG PC Suite and clicked on Device -> Emergency Recovery or something like that. Make sure you don't have the local server setup from cmahendra's offline KDZ flash method. Then you just find where you put in your device's IMEI code or whatever and click OK, it'll flash the stock v20F firmware straight from LG's server to your phone! Then you have to re-root (I recommend LG Pwn method) and install busybox and then flash Artas locked CWM recovery. About the whole bootloader thing, just wait. @carloswii5 is making a video to upload soon on how to do it, that's when noobs like you and I can do this.

What unlock BL thread did you use? It's possible after issue "adb reboot oem-unlock" and your phone just normal reboot. Many people has that problem. Let me guess it about new board hardware version. But some people keep trying to unlock and they success in third or fourth try.

I have read working signal is needed and important to ul bootloader on 20b and I cant seem to get the radio working
ive heard I need to swap radio..which I did(flashed the radio.zip) from his files( after I rooted and confirmed root on 20b)
