L9 p769 V20H unlocking bootloader issue - LG Optimus L9 P760, P765, P768, P769

Hey there all,
I have followed any and all threads and guides to flash the 10A and the 20B European ROMS so that I can attempt to unlock the bootloader on my P769. I follow all of the steps till you get to the point where you click on "Normal web upgrade test" to start the upgrade and then shttps is supposed to step in and block the LGMobile Support Tool connections to it's server, but all it does is bring up the current installed Support Tool and gives me an error and crashes instead of starting the flashing process. Does anybody know where maybe I have missed a step or maybe something that I am doing wrong to where things just aren't clicking right??
I have attached what I am getting as my result. I hope one of you really smart guys out there can point me in the right direction.

uninstall the support tool, modify hosts file, reinstall support tool and try again.

the only reason you're crashing on that version is it's the new one... so something didn't get set right...

Is there a good way to make sure anything LG related can be totally deleted so I can start anew like drivers and whatever else that may be messing with this process?

[Q] Cant unlock bootloader through HTVdev

Hello eveyone
I am trying to root my legend. First, I tried the method on http://wiki.cyanogenmod.org/wiki/HTC_Legend:_Full_Update_Guide
It has 2 steps: downgrading and rooting.
I completed whole step 1 (downgrading) and went back to android 2.1 through the RUU.
Then I came at step 2, rooting the device. In step two of the rooting, it gives a link to the rooting files. This mediafire link is dead.
I went online searching for another link, and eventually i came at http://forum.xda-developers.com/showthread.php?t=1680584#3 wich guides to do the root through HTVdev. Before i actually went and tried this i needed a working phone for work so i did a full reset and updated trough android OTA update.
When I tried to unlock it through HTVdev, i runned into a problem.
Before i even could start, it asked me to update my rom with one of the given links. It says:
NOTE: If you do not find your ROM version in the table below, and your ROM version is newer, then your device does not require the RUU. Please bypass these steps and continue to the next page.

So my problem is, my version is not listed, but it is ALSO NOT newer than the versions listed below. The versions that are listed are:
3.14.161.1
3.14.163.1
3.15.1600.
3.15.178.3
3.15.405.3
3.15.708.2
3.15.709.3
3.15.720.3
3.18.751.2
3.19.1010.1
3.20.666.1
3.30.415.6
3.30.466.6
Click to expand...
Click to collapse
My problem is, i got version 3.15.405.7, very similar to the one listed, 3.15.405.3. First i skipped this part, and went ahead to follow the steps anyway. When i had to type fastboot oem get_identifier_token (step 8) in command prompt, it supposed to give me a large list of numbers.
Mine did nothing, so i knew i was wrong. I tried all of the steps a few times but with no effect. Then i thought, can't i just use the RUU of 3.15.405.3, maby then it will work?
But when i tried to run it, it didn't work since i dont have the right version to begin with.
So now what, can anybody help me? I realy want to unlock my device, it is so slow on stock 2.2 i'm getting crazy
I'll trie to follow every suggestion somone gives me but i cannot guarentee i can do everything since i'm a bit new to this stuff (although i know a lot about computers)
Thank you very much!

[Q] Root ICS with New Lelus method & Offline Flash - Newbie question

Hi thanks for looking.
I'm a new register and newbie to rooting. And I'm currently following
[ROOT ICS L9 GUIDE] Root ICS with New Lelus method & Offline Flash [11-Mar] guide.
http://forum.xda-developers.com/showthread.php?t=2173465
Unfortunately, I'm a new user register so I can't post on that message thread. So, I was instructed to post my question here.
So, I'm following the guide word-for-word from steps 0 - 8 and now I'm up to the part where it says to "When done, REMOVE USB CABLE AND POWER OFF THE PHONE."
Okay, now question:
[Q]1: For step 9a and 9b. When do I actually perform these steps:
So, currently my USB cable is removed and the L9 is power off from the above step in STEP8.
9A. says to Add lines in "hosts" file as mentioned in step 1 of this post.
So, I'm going to assume that I add the Hex-Edited BIN file and related KDZ file that I've downloaded in STEP1.
But where do I add said lines to?
[Q]2: okay so for step 9b. Start "SmallServer" as mentioned in step 2 of same post.
Where is this "SmallServer?"
In step 2 of the same post, I've already Downloaded Root_and_Flash_Guide_byCMahendra(date).zip file (attached with this post) and extract in your C-Drive.
and gotten three folders named "C:\RootLelus" and "C:\RootFlash" and "C:\shttps"
[Q]3. Okay, now that I'm just advance reading to STEP10 that asks to follow Steps 3-10. Does that mean now I have to reconnect my phone back to the PC from STEP8 and go through the steps 3-10 again, since I've already gone through it the first time around.
[Q]4. the Actual Magic.
So, which LG UPDATE TOOL is the step 11 referring to? Is this when I'm installing the driver to my PC in Step 3? Or is said LG UPDATE TOOL sometime during step 4-8?
Sorry, for all the confusing NEWBIE questions. I'm just trying to follow all the steps without bricking my new phone.
Thank you in advance for your patience and assistance.

OKay, sorry... another question.
So, I'm now flashing with the PHONE UPDATE TOOL and after going through all the steps and the 'MAGIC' swap. My phone reboots and when it turns on I get an error message:
[Driver Software Installatior
Device driver software was not successfully installed
Please consult with your device manufacturer for assistance getting this device installed.
OMAP4430 Device unplugged]
Please let me know what I did wrong and at which point in the process do I need to repeat all the steps again to root my phone.
Do I go back and use the [GUIDE] FLASH L9 Factory ICS/JB ROM WITH OFFLINE FIX + UNBRICK
http://forum.xda-developers.com/showpost.php?p=36351786&postcount=1
And start with STEP7 and rerun the PHONE UPDATE TOOL and MAGIC swap?
Thanks in advance.
Hmm I remember getting a driver installation error when trying to put the phone into 'software upgrade mode'. In my case, I held the 'volume up' button down and plugged the USB cable into the phone. Then I got the error notification that the OMAP driver didn't install. Yet right after this, another set of drivers installed (I'm guessing the computer took a minute to recognize the different mode of the phone?). These new set of drivers installed successfully and I was able to root with no problems.
tl;dr I disregarded the OMAP error, and rooted just fine with no problems
Have you checked if you got root after flashing? If you do have root, then you should be fine.

Protomartyr,
Ohhh..so that error message isn't the cause of my phone not being able to successfully root, huh? No, my phone still isn't rooted. Basically when my L9 is successfully rooted is when all default icons on my phone are gone right?
So, a couple new questions then.
[Q]1: Okay, I know when it's time to flash you have to hold down the volume button and then plug in the USB cable into the phone. How long do you hold the volume button down? I hold the button down until the phone turns out with the S/W flashing message and then I let go. Do, I need to hold down the button throughout the whole flashing process?
[Q]2: How can you tell if the phone is rooted? Does it look different?
I'm guessing my phone is still haven't been rooted and I'm only getting this error message.
[Driver Software Installatior
Device driver software was not successfully installed
Please consult with your device manufacturer for assistance getting this device installed.
OMAP4430 Device unplugged]
So, if the above error message isn't the cause of my failed rooting. At which step do I go back and reattempt to root my phone?
Do I go back and use the [GUIDE] FLASH L9 Factory ICS/JB ROM WITH OFFLINE FIX + UNBRICK
http://forum.xda-developers.com/show...86&postcount=1
And start with STEP7 and rerun the PHONE UPDATE TOOL and MAGIC swap?
You wouldn't see a difference once you rooted right off the bat. You should see the SuperSU app in your apps list if you followed the procedure. However, having the SuperSU app doesn't mean you are rooted (SuperSU binaries must be installed as well and this requires super user privileges).
To check if you have rooted successfully, the best way is to just download 'Root Checker' here (Click Me for Link)
Once you install Root Checker and open it, you should see a notification asking for Root Checker to get super user privileges. Accept the notification and you should see 'Root successful' or something along those lines.
Let me know if Root Checker says 'successful' or not, and maybe we can troubleshoot after that?

Hey Protomartyr,
Cool, my phone installed SuperSU in my apps menu and Root Checker says my phone has been rooted. Now I just need a guide or info on how to remove the bloatware and what I can do with my rooted phone. Thanks for all your assistance and guidance.

No problem. Congrats on getting root :highfive:
As far as removing bloatware safely is concerned, you might have to ask someone else (I'm still a newbie at these things). You can remove/disable them using Titanium Backup (from the app store). Proceed with caution though, as you don't want to remove an app that the phone needs to function. From what I hear, it's safer to just disable unneeded apps (though even then you must tread carefully). Titanium Backup is also useful for backing up all your apps/system apps/user data.
As far as what you can do with root...well that's like asking how many drops of water are in the ocean You can fully customize your phone and even install a new ROM; just naming a few. You can get a better picture of what people are doing with their phones in this thread [Click Me] as well as the other LG L9 threads.
Enjoy!

Thanks again for everything Protomartyr,
You've been really helpful. Okay, another question. So, now that I've rooted my phone. Do I now go back and turn on the Lookout Security Antivirus, that I've had to turn off during the rooting process steps? Or would I need to allows need to leave it off to keep my root active?

[Q] All in one Root tool

Hi folks. I am not allowed to post in the developer forums since I am a new user so I figured I'd try here and hopefully some developer will be watching this forum.
I want to root my new Verizon Samsung Galaxy S4. I found the thread regarding the all in one tool for doing the root and installing recovery.
I followed the instructions, downloaded the tool, connected my phone, invoked the tool and selected Option 1 (Root my phone). The cursor skipped down one line and then nothing. I waited 15 minutes to make sure it wasn't doing anything but that's it, nothing.
I am new to Android and therefore new to Rooting so I thought this all in one tool would be perfect for me to get the job done. But I now have no idea why nothing happens when I invoke the tool and select Option 1.
Is there somebody in this forum who can help me please?
Thanks ............ Rob

Once you select Option 1, you need to go back to the main windows to uncheck one box (F something) and then click start before it does the rooting. I missed it yesterday also and just keep waiting until I realized there was a step I didn't do.

Did you enable USB debugging and third-party? USB debugging can be found by tapping on build number (i think) under about phone like 7 times. Developer options should appear in your settings after that. Third-party sources is under security I believe. Hope that helps!

I actually found my problem. Even though I had the usb debugging flag set, when I tried to root, a popup window came up in the background asking me to confirm that I wanted to enable usb debugging. Because it was in the background I kept missing it. Once I saw it and replied, everything worked perfectly. Hope this maybe helps someone.

Root just allows you to hack the software on your phone, and the "unlock" refers to the bootloader. It does not unlock the phone for other carriers; this is done (from what I understand) by dialing a specific set of codes, generally provided to you by the original carrier of the phone if you have an account in good standing with them and you tell them you plan on travelling out of the country and need to use GSM. I have never needed to do this and as such only have a minor theoretical knowledge of the subject; I would appreciate it if somebody with more knowledge on this would confirm or deny my suspicion that you are better off trading the phone for an AT&T/T-Mobile one that actually was meant for GSM, or otherwise obtaining one.

This is the original bootloader; not the stock firmware. You need to flash this after you successfully root, start the phone, start SuperSU, and update the SU binary.
The full stock firmware is rather large and available here:

thanks for telling me this first of all, so let me see if i get this right and im hoping you or someone will tell me if im correct or not. The all in one root method does that take care of the whole SuperSu, and update part or do i still need to do that after the root tool does its business? With unrooting do i just need to flash the stock firmware in odin use triangle away and i should be good correct, im not quite understanding the whole thats the original bootloader....the file that downloads is a .tar i thought that was firmware/rom....what do i need the original bootloarder for exactly?

The original bootloader is locked and doesn't allow for us to use the exploit to install SuperSU and root the phone.
We are installing the unlocked bootloader via Odin...
Then running motochopper to exploit a vulnerability to gain root...
Then MANUALLY (this can't happen automagically) opening SuperSU and updating the SU binary...
Then rebooting the phone to make sure you still have root (personal preference)...
Then re-loading the original bootloader (we don't need the modified one anymore!) via Odin...
Then we are done!
The steps in the how to are very precise and accurate. If you would like to PM me, I am available for another hour or so.

Well said. Only correction is the bootloader still remains locked. The recoveries included are loki patched. This bypasses the bootloader. All roms and kernels are loki patched so flashing them is safe. This is as close as we're gonna get to an unlocked bootloader for now.
Ah. I was under the impression the bootloader was unlocked. Thanks for the info.

Could be a couple of things first make sure your using the cable that came with your phone. Try switching usb ports. Alsi try rebooting your pc

Bricked Your Newly Rooted Tungkick's H900 TOT? Fear not. ;)

As we all know, Tungkick's Root Method by TOT instructions, are to be observed and followed step-by-step in order to achieve proper root on this device. One of the instructions is to leave the settings in LGUP, as "Refurbished".
Well, after accidentally flashing a zip file on my H900, my phone went through several boot loops and started giving me a headache from Hell. After considering the instructions by Tungkick, I thought, "What would Wesley do?" Think outside the box. Since I had not set my phone to MTP, I was not able to make any type of connection with the LG Bridge app, but once I crossed my fingers, ran LGUP and chose the "Ugrade" option, the phone rebooted like out of the box, and the good thing about this is that YOU DON'T LOSE YOUR DATA (pics, music, call logs, etc....) The recent lags my phone had been experimenting, went away and I was able to recover all my data using LG Bridge.
So, there. I hope this comes in handy for anyone experimenting issues and are Rooted.
Do you have a tutorial? Or links to this! I have the same issue please.
Nvm found the information tnx.

what zip did u flash? if u got bootloop with "fail *something*" on the top left, it's because u didnt unlock bootloader using fastboot (dev setting is not enough)

Follow Tungkick's tutorial to "re-root" your phone, but instead of selecting "Refurbish", you'll select "Upgrade".
It's that simple.
If you have Xposed, you'll need to reflash it using Flashfire, and you'll have to re-install BusyBox. The rest of your apps keep the data, just as a computer would if you would to do an "upgrade" with the "without losing your files" option or something like that...sorry, it's been a long week.

No Download Mode - Only Fastboot

Hi,
I tried to upgrade my US998 from Oreo to Pie using LGUP patched. The upgrade process went well until the phone restarted and have this error message:
"Your device has failed a routine safety check and will not boot..."
I did try using LG Bridge to fix = not working
I did try fastboot boot laf.img (using extracted laf from H93031a_00_OPEN_EU_OP_1105) not working.
Any other solution?
Thanks
This Post got recommended to me. I am a Samsung user so my answer will probably be very stupid.
If you have fastboot, why don't you flash a recovery and a custom rom? Ik stupid but it's the only thing that comes to my mind since i don't have a LG phone lol

Is that "Download mode" the same as the Samsung one? How do you NORMALLY access it?

I'm not sure. Normally I access download mode using volume up and power button. The download mode was there for a sec and then the screen back to
"Your device has failed a routine safety check and will not boot..."
again.
Ah ok so now I understand.
But why don't you unlock your bootloader then if fastboot works? Do you know for sure that TWRP doesn't work?
I really want to help but I don't have a LG phone

EDIT: The LG Bootloader unlocking page is "under construction". Guess you have to bring your phone to LG for them to fix this...

Unfortunately my LG V30 is US region. The official bootloader site not support my phone. Thanks for your info anyway
I'm not sure why a Samsung user was recommended this post. And no offense to the Samsung user, but the process for unlocking, etc is VERY different for Samsung than it is for LG... so I recommend not worrying about that. Believe me, I know, because I'm researching switching to a Samsung in the future, and the process is very different!
That being said, the best resource here is the WTF thread with the post by ChazzMatt. That post has everything you need in one place.
jacoozie, the error you're getting indicates that you had a non-stock phone when you flashed the KDZ on an unlocked phone. For this reason, it's no surprise you got this error - the phone must be COMPLETELY STOCK for a stock KDZ flash. I'm guessing you had TWRP or something else installed, which is causing this problem. Once you unlock, you cannot just flash things willy nilly... and generally you don't flash with KDZ unless you're trying to change models (aka Frankenstein) or on the way to a custom ROM.
It sounds like you've done some unlocking rooting... if so, I recommend you start over with the WTF thread, read it VERY CAREFULLY and ENTIRELY and then reflash as instructed there. I'm guessing you may need to go back to KDZ Nougat and then work your way forward. If you have questions, ask in that thread... but you shouldn't have any questions as the thread is VERY complete (been updated all the time with very detailed information, so everything is in there).

Thanks for the reply.
I didnt install TWRP or any recovery tools to my phone. My phone bootloader still locked thou.
I have read the WTF thread but the problem is I cant get into my Download mode.
Ok, what steps are you using to try to get into download mode? Presumably turning off the phone, then holding the volume up button and plugging in the USB cable (other end already connected to a Windows computer), correct? If that doesn't work, can you try other USB cables? Sometimes a bad cable could prevent the phone from going into download mode.
