What events lead up to your bootloop problem?
If you didn't unlock the bootloader you should be able to get LG or your carrier to flash for you.

To tell you the truth I kind of don't know because it was working fine the day before this happens and when the next day came I try to check the time but the phone was dead.....
Then i relized that 2 days before this happen i tried rooting it which i wasint really good at or even knew how to root it so i download a kdz file and im guessing that is what probably caused but what i dont understand is when i try recovering it using lg support and when it gets to the update mode it keeps on stopping at 50% saying there was a problem between the phone and pc I tried using another computer and it told me the same problem.
P.s. I took it to a phone store they said it could fixed for 60 and they even said it just need an new kdz

Maybe try a different .kdz from here: http://forum.xda-developers.com/showthread.php?t=2107971
Sometimes files fail to download the way they should - maybe you have a corrupted kdz file and a new one will work?
Edit: Or maybe try the official update, you have instructions here: http://www.lg.com/us/support-mobile/lg-LGP769BK
P.S. If I was you, I'd simply unlock bootloader, flash a recovery and format from recovery. Then, I'd flash a ROM.

Use the offline kdz method to get back on 10G rooted. Search for lelus' screen fix and apply.
Basically follow links here http://forum.xda-developers.com/showthread.php?t=2198114
Skip the flashing offline kdz of euro 20b, do the rest.

You can also use Smartflashtool and just pick the .fls file. Works without any problem Way faster and easier

Can you elaborate on this? I've tried to use the Smartflashtool to fix this problem and haven't had any luck.
Havent used it in a long time, but in fact you only need smartflashtool (sft), the fls file you extacted from the kdz file and that's basically it. Reboot your phone in download mode and open sft. In there change to the correct tab, choose your fls (dont remember which field, since it is REALLY long ago) hit start and it should update your baseband.

Great idea but how do you get past the magic number does not match issue? If you have the model.dll file for the p769 could you please forward so I can replace the one I have. Mine is for the 940

Like I said, I only inserted the fls file and there was no magic number error.
Maybe check the p970 forum, there is another version of SFT. Maybe it was this one, that worked.
Well that would be great if we could get that to work for our phone because it take like three minutes to flash. This would be an alternate to the offline flash.
P769v20h- 'tis the season to give thanks so push the button already!
Ok again:
It works to flash the BASEBAND ONLY!
It does NOT and I repeat N O T work for the full firmware.
For this to work we would need a new modell.dll, which we probably can only get from LG itself, or a REALLY good reverse engineer here on the forum. But I really doubt anyone wants to do this. I was also talking to xonar_ and he is like an android god to me. He confirmed, that it's very hard, up to impossible to get this to work. I also tested a pack made by him, but it also wouldnt work. If anyone is interested, go ahead an contact him. He is a really nice guy and explains everything very much in detail, if you nicely ask for

Fixed my touch screen on LG P769
I am now able to fix my wonky touch screen finally. Thank God.
After spending the whole day Saturday to unlock the bootloader and install custom rom, I finally gave up after 24 hours. Next I wanted my phone to be in working condition by Sunday night.
I just flashed the stock kdz (V20h) for t-mobile usa. I had this one originally. My display was okay (after initial switch off and on) but touch was still not good.
After that I just did root my phone and installed Super Su. as mentioned in other threads
Then followed the command to cat v6.bin into some firmware file, as mentioned in other threads. It feels so good to get the touch screen working again.
The display is still mirrored when phone boots, but first time i switch off the screen and on again, and it's fixed.
I will edit this post, later with more details and links later.
Also, I did a Factory Data reset, after flashing v20h kdz. But I believe it was not required. In fact, it was very difficult to enter passwords for wifi, google play account etc with the wonky touch screen.
Sounds like you got it under control. Here is a zip file Kuma made that I use when I try to unlock bootloader. Sometimes I have to install it twice but it's the fastest way to get back to normal

I think the easiest way is to use LG mobile support tool. refer to this member post http://forum.xda-developers.com/showthread.php?t=2456558&highlight=encrypt
- Boot you phone to S/W update mode
- Run LG mobile support tool (B2CAppSetup.exe)
- Select recover you phone from menu and wait for about an hour
- *Dont forget to comment lg server that you add in host file for offline flash
There're also other way to fix it, if you can boot into Stock recovery by Holding vol- + ... (I can't remember ), but this combo may hard reset your phone if you don't have stock recovery. In stock recovery mode you can use adb to push and replace busybox. I don't try this myself but some member unbrick their phone by this method.

I can get to the factory hard reset but it says secure booting error Cause: boot certification verify. I cant get it into fast boot, only download mode. I downloaded LG KDZ updater but I am unable to find a firmware file. I tried Original LG FIRMWARE, but it never works for my phone and IMEI. I have tried a few, and searched, and pretty much frustrated right now! lol
So any help would be great!

Flashing a rom for an locked bootloader phone?
Can you fix it by kdz offline flash?

My bootloader is unlocked.One day on stock rom like a week after flashing a fresh kdz my phone just crashed so now whenever I start my phone there is a dead android with a red triangle over it. Whenever I flash a new kdz it changes nothing, my phone still boots to a dead android with a red triangle over it. I think it may be stuck in a recovery bootloop. So after I thought that, I used omap4boot and entered fastboot mode and flashed me a new recovery. But now in the recovery I cant do anything it says something like E error cant mount \cache or sd card and things pertaining to that. The recovery is also mirrored. So after about a month of posting on xda in the questions and l9 questions areas I decided that I would just try and replace it. So I flashed ics u and x boot which when I enter s/w upgrade mode doesn't say bootloader unlocked then I removed the custom recovery which makes it just load up to the lg logo and freeze
What questions might they ask me if I want it fix is there anything not to say to them
If you want to try sending it on warranty you can start here: https://www.lg.com/us/support/repair-service/schedule-repair
I don't know if they will replace it or repair it. I also don't know if unlocking the bootloader voids your warranty.
I sent my rooted P769 in under warranty. They replaced the flash memory and sent it back with the latest FW about a week later. Works fine now.
It only cost me about $5 to mail the phone to Texas. YMMV

You better say nothing about your phone but just "IT FREEZE" and let them check themselves. Before that I suggest you flash the ics kdz first because ics don't have bootloader checking and your phone can pretend to be "Offical".

Messing with the bootloader voids the warranty. So you'd be better off just booting to LGs logo and NOT the Security Error Security Error will tell any tech right away that you've been doing things you're "not" supposed to do.
Yeah be tactical. If they anyhow come to know your boot loader's status then you're screwed. I mean the security error stuff.
