Nope, they are two different phones so it's impossible to use any work that is being done on their device on ours

how much going wrong are we talking? and can it be fixed with reflashing the kdz?I ask these questions because this is currently my only working phone ( I "dissected" my galaxy exhibit in a fit of boredom)

I would say a possible brick requiring a trip to LG Repair Center. But that's what warranties are for.

I'm afraid what it can't be undone by KDZ reflashing, d'oh

If I had a backup phone I would dive right in but I recently sold my HD7, so it's a no go. Good luck whoever is brave enough.

I have 2 phones so I am willing to give this a try even though I may brick it.
Here is my device status: P769BK 10g rooted.
I need to know exactly how to attempt the bootloader unlock. Do I need CWM? What software and steps to flash? etc.....
Ok I'm about ready to give this a go. I've familiarized myself with fastboot, and will flash u-boot and x-loader thru fastboot. Does anyone have an original u-boot and x-loader so I can unbrick my phone when this doesn't work?(P769)

Here seems to be original files with patched files. And IDA working files... Take a look in archive.
Ok I flashed patched bootloader thru omap4fastboot. Upon flashing u-boot and x-loader the phone is bricked won't turn on or anything. Was able to go back into fastboot though and flash the original files back. Its back working again, however when booting up the screen is mirrored(just picture not touch) it stays inverted like this until I lock and unlock the phone after that its fine until next restart and a very minor inconvenience until I can get a hold of P769 u-boot and x-loader from some kind person. So confirmed not working at least on P769.

@Tablechair
Great you have tried without fear and congrats for recovering back phone when it failed.
But tell me, was your P769 already had the mirror issue due to earlier P765 flashing? Or it appeared after above procedure you performed and now screen working fine?
What happened was:
I did not have the original bootloader file from P769. I only had the unmodified files that payday was working on. I suspect he had files from another device variant P760 or something. The screen mirror thing I haven't experienced before. I believe if I can put the proper files back it will be fixed. So, I really need someone with a full P769 dump to share with me u-boot and x-loader. The screen problem goes away shortly after boot, but I've noticed another symptom when I try to flash using the method in your thread the tool hangs after trying to contact the phone. It was very late though I could've overlooked something even though I've used that method before I will be trying again tonight after work.

xmmm maybe someone with a p760 variant to try, but first we must find a way to safe revert the trouble before trying

Now I start to have a picture of the pioneers in tech
Quick question: is this your primary phone or just a fun/backup phone?
This is my primary phone. Thank you for your kind words but, it was actually a really foolish thing to do. Next morning after this I tried a few times to flash a kdz to get root with Lelus's new method, but it does not work something got really messed up from flashing stuff in fastboot. Now after attempting to flash kdz I get security error again, and I will most likely have to send my phone into LG for warranty service. I'm not upset about it though, if I saved a few people from trying the same and bricking their phone I am happy and it was worth it.

Use the offline kdz method to get back on 10G rooted. Search for lelus' screen fix and apply.

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

Ok so a spark bursted in my head at 2 in the morning of an idea and it has worked so im noticed that alot of people struggle to unlock the bootloader but not because the steps are hard but there is one missing part i have found which is it needs to have a signal connection to you provider for it to work and the thing is when you flash V20B the radio is different so it sometimes might get the signal but that is like what 1/100 or something like that haha ok back on track my idea was what if i install the radio for the P769 which was extracted for the workaround that we had for the JB manual install via CWM on V20B and we would a working radio so the bootloader would unlock on first try and i tried it and it worked muahahaha ok so what to do
Well before you go flash V20B to make everything easier make sure this app is already installed on your phone
Artas Bootstrap Recovery Installer and make sure you have the radio zip on your sd card
Then make sure you have debuging on and show touches on also so everything is easier
Now flashing set up first go download the JB guide its in the root l9 offline method and download the bin for V20B ok so now flashing run the rootl9 bat file but for JB then start the flashing process and were going to swap the bin then after swapping let it do its thing
ok after it finishes go to supersu install the binary and after that go to artas bootstrap recovery and install it then boot to the recovery after in recovery flash the radio zip and let it install it takes a while maybe a min to 2 minutes and after it installed reboot and then you should see you have signal hoorah , now just let it sit for 30-40 minutes then after the time is up run the command "adb reboot oem-unlock" from your computer and it should take you to the acept to unlock it and just press volume up and tada you have unlocked bootloader on first try
Sorry For No Links but in a Hurrry Good luck

Ok, I hate being hand held, but I have a question. Fm my understanding these are the steps I should be doing to unlock BL and Rooting the Sweet LG L9 P769 below:
1. First flash the V20B_00.KDZ Process.
2. Next Unlock the BL
3. Then Root the device Process.
4. Install recovery cwm, and the RC5.
Please let me know it this is correct, and add anything that i should lookout for.
When I start this process I'll make sure to take Note to write a first grader process.
I love this device for the price i pay for it, and i love a challenge.
My future device will be a LG optimus G Pro, but until then I need to get the LG L9 P769 hacked.

So I got my bootloader unlocked but unfortunately during the second flashing process the up test program froze and errored out, now my phone isnt recognized in adb devices and will only go into s/w upgrade mode.
Edit: I also tried fastboot and was able to sucessfuly get into fasboot but flashing the stock x-loader and u-boot was unsucessful and fastboot just gave me the "waiting on device" message.
Edit 2: So after quite the night of running through your guide and a couple of hard ships, I have to say this a very well written guide and it would have worked the first try if I had been doing too much multitasking while in the second flash process.
Overall was easy to follow and I got through after having failed attempts with others guide before due to oem unlock command not working after waiting.
Also I highly reccomend anyone who is going to try this to at least give the other tutorials on unlocking the bootloader for the p769 a solid read through. It will make a difference in what you understand and dont.
Lots of props and I look forward to seeing what you do for our phone in the future!

Edit 2: So after quite the night of running through your guide and a couple of hard ships, I have to say this a very well written guide and it would have worked the first try if I had been doing too much multitasking while in the second flash process.
Overall was easy to follow and I got through after having failed attempts with others guide before due to oem unlock command not working after waiting.
Also I highly reccomend anyone who is going to try this to at least give the other tutorials on unlocking the bootloader for the p769 a solid read through. It will make a difference in what you understand and dont.
Lots of props and I look forward to seeing what you do for our phone in the future!

confused abotu superuser part.....
So carlos it looks like i was having the same issue as you that you posted in another unlocking bootloader thread, cant get past the adb oem-unlock. It just keeps doing a normal reboot.
I saw you got it to work with the wifi connection, is that confirmed needed for every attempt?
also in your guide you have the following command: Go to the Superuser App and update the binary the normal way
I dont know what that means , could you explain that part a little better. Thanks
If my phone is still under warranty would I be able to get a replacement one if it has software problems like being stuck at lg logo and saying security error?
I think they wouldn't replace it but fix it for you. What have you done to your phone?
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.

I cannot answer that, sorry.
so i've tried everything to unlock this v10 and so far no go.I need an unlocked phone modem to compare to a locked one and see exactly causing the lock or if i can just flash an unlocked and it will work?
Also can't flash modem of any other variant or else you will be bricked for good.
so i tried flashing system and boot partitions of a lot of different variants to try and get unlock prompt to pop up.
H900(at&t) no boot
H900PR(brazil ver) same thing as at&t no boot at all
H960TR(turkey) hangs on boot animation
H960 (vietnamese ver) same thing as with 960tr hangs boot animation
F600k(boots perfectly, but no sim unlock menu)
F600L(again boots perfectly but no sim unlock menu)
Starting to notice anything? similar model names have similar behaviors ex. h900 and h900pr show exact same boot fault
So, the only possible way is the modem!
can someone with a unlocked t mobile modem please upload theirs. i'm going to flash the unlocked modem and use the f600k system so no tmobile bull**** can lock it again.I really think this could work as long as no stock tmobile rom is installed.I would really really appreciate it as im stuck with this phone rn.
ALSO , here is how to easily get modem partition if you have root.Download "partitions backup and restore" in playstore by wanam
check firmwire/modem in green and backup and that's it! tested myself and works.
So please if you have a unlocked tmobile v10 and are rooted it would very helpful if you could take a few mins to backup modem and upload it.
ok as an incentive im adding a 10$ bounty through paypal.i need the following 5 modem partitions backup using flashfire.
Modem firmware aka modem
Modem firmware data #1 aka modemst1
Modem firmware data #2 aka modem st2
Modem firmware FSG aka fsg
Modem firmware SSD asa ssd
Download flashfire by chainfire from playstore and backup the above partitions and upload them.i've backed up these partitions my self on my v10 so yes it works.I only put a bounty because this device barely has any dev half of these v10 are dead lol also im patient from trying to unlock this thing ffs.First one with the CORRECT partitions i will reach out via pm.
Quick 10$ takes no more than 10 min!!
Backing it up right now as I type this. Whats the best way for me to upload this for you?
EDIT: here is the link, backed up via Flashfire and then zipped up, no password. My phone is currently running stock rooted Eliminator ROM (software version H90120L) https://www.dropbox.com/s/a3l518nse4vkj4q/LGv10Modem.zip?dl=0

Thank so much man for taking the time.no i dont need the compressed ver.i meant to ask if your v10 is network unlocked (permanent via the t mobile device unlock app) . I need these modem files from an NETWORK UNLOCKED device.if its not i really really appreciate it anyways!i should be been more clear lol

Not sure if I did that or not. The phone is paid off so I would assume I can put it on another network. I've moved on to the newer model v20.
Question, why would the modem firmware change whether it's unlocked or not? Wouldn't that be done via firmware update?
Sent from my LG V20 using XDA Labs
Nope.tmobile has locked these down using the device unlock app.if you never used it on another network other than tmo then its most likely not network unlocked.even if its paid off, you have to contact tmo to request a permanent unlock.once they give you the green light for the unlock then you just use the device unlock app that comes on the tmo phone and hit permanent unlock. modem files hold the unlock info in this case.as i said above ive tried roms from even the international variant only to be greeted by the network locked notification.im sure theres at least one person with a network unlocked tmo v10 lurking around these fourms lol.again i appreciate you taking your time to help!
I will look into getting it unlocked. No big deal for me to do so since i don't use the phone anymore

Here you go my friend, V3 is device unlocked. Used the T-Mobile app Device Unlock. Went through the process. Phone rebooted and a toast notification popped up saying phone permanently unlocked. I suppose you can compare both V2 and V3 to see what changed?

Well, i just gave up.i tried everything, this phone is just locked down tight.The phone would not flash the modem.bin at all through fastboot or flashfire since it is a locked partition.I managed to flash the modem firmwire 1 and 2 since they are not locked partitions through flashfire.Phone still not unlocked, so i tried flashing http://lgviet.com/forum/threads/rom-radeonmaya-t-mobile-h901-v4-0-update-19-11-2016.58894/ rom and it has a working sim unlock menu but it says phone cannot be unlocked or something.so i flashed the modem firmwires again and run the sim unlock app and it prompts me for a code! I had my unlock code from ebay and entered it and it said network unlock successful and the phone rebooted itself.But after rebooting it still showed network locked.i think it needs to be on stock rom.i tried porting the sim unlock menu to stock but it doesnt even open.i just gave up on this phone, i just use it like an ipod lol.we have unlocked modem files though i cant find a way to flash it.it just might be what we need.flashfire wont flash protected partitions (modem is protected) and also fastboot keeps through an error when trying to flash anything.the only way to flash the unlocked modem bin is with LGUP.ive managed to extract stock kdz and replace the modem.bin with the unlocked one but i dont know how to convert it back to a kdz or tot so we can flash the modified kdz.also maybe 7.0 has some modem changes? Or i might just try flash modem of korean variant though i would be just testing my luck as it will result 99% a hard brick. 4 ways to do possibly unlock this
Port sim unlock menu to stock rom 99% chance your phone will unlock
Flash modified modem.bin somehow through lgup or lg flashtool.good chance this will work as well
Wait and see if you can expliot something in nougat .if were lucky this might have something.
Sending AP commands through Modem.i tried this myself.it seems you can only communicate with modem with the korean or tizen rom.you can send the command AP%ULCW.
UlCW=unlock code write.so you can write the unlock code through direct comm with modem via usb but i dont know the correct format to enter the code as it keeps throwing an error.
Still thanks to @amoot329 for coming in clutch with the files.when nougat comes out i'll try messing with it again but honestly this phone is useless lol.
