(FlashKDZ/Root/Recovery/Hiddenmenu/troubleshooting) (noob2noob guide)
Okay, this is my first thread on XDA, the reason I'm making it is there is a lots of problems with progressing to lollipop. All of this is already mentioned in the forum, but this way it is much easier since it is all at one place. If I'm doing something wrong please warn me with explanation how to resolve the issue. If I'm posting in wrong forum section please move my thread where it is supposed to be.
1. Before doing anything check if your phone is ready to get updated:
1.1 Do you have a stock Kitkat rom or at least a rom that is kitkat based, since there can be a problem with partitioning if custom lollipop rom is installed
1.2 Create a backup. Don't be lazy LG backups will not help you since they can't go from kitkat to lollipop, don't try to do it from recovery because you will lose custom recovery. Copy your files from phone including extracted contacts, and back it up online with google or some other backup providers.
1.3 Check if you have a latest touch firmware, because you might have a problems after installing lollipop and it will be hard for you to check for updates since your touch might become useless.
1.3.1 To check it go to hidden service menu by typing 3845#*802# and go under HW Device Test, then Touch Test then touch firmware version and write everything down. After that go to touch firmware upgrade and after 15 seconds compare the touch firmware version values with those you written down.
1.4 In hidden Menu you can also go to wlan test then ota setting to check if it is disabled on your phone. After that check again if there is OTA updates for your phone, and also check if there is PC suite Update.
1.5 Check your phones version if it is D802, D800 or something else, and check which rom you have installed. You can do this in settings about phone or if you are happy about hidden menu found, go there and into settings then version info. This might not be interesting or fun to do, but it will save you the trouble if something goes wrong, because you will know what to ask.
1.6 Last but not the least, before starting to flash fill up your battery, i've read some posts that say there are problems with wrong capacity shown, and a lots of battery drain problems, and only solution till now is to have a full battery on start.
2. You will need LG FlashTool and of course installed drivers for your G2 on your PC.
All of that you can get in the thread by @quangnhut123 .
2.1 Just a bit of precautions, don't forget to always copy a kdz file in to Flashtool folder and then start a tool. All should look the same as in that thread, except you should always use CSE method because with this method you will install kdz from scratch, removing everything from the phone.
2.2 You should find the kdz file which suits for your phone on site . You can check for kdz by typing in imei in check new firmware section or find the one for yourself by searching the site. v30a is lollipop open while v30d is for branded G2's.
(I've read that this site is not allowed by Xda moderators, so if I can't post it please give me info on where should we download kdz's from).
2.3 I think it's all pure logic now but lets say it one more time. You have downloaded kdz file, and put it inside LG Flashtool folder. You should now start Flashtool and get your phone into Download mode. To do this you need to hold volume up button on turned off device and connect usb cable while holding volume up. Now just cse flash.
2/3 This is troubleshooting step, if you have a problem ask and i hope this great community will help you like they did to me, and ofc I will do my best to help.
3. Now we go to rooting.
Here is the thread by @avicohh which worked for my D802.
Just follow his step by step tut and you will have a rooted phone
3.1 The only issue that might happen here is you are stuck with # and adb waiting for your phone. To resolve this just go into download mode manually.
4. Okay rooting done, now let's go to custom recovery install
It's easy as installing an app from google play by @bender_007
4.1 After installing it open the app and follow the on-screen instructions. If it fails for the first time, try it few more times, it will eventually work. (OFC. I didn't install it with only one try).
4.2 To get into custom recovery hold volume down and power button till first LG sign shows up, then release both buttons and quickly press them again. It will ask you do you want to do factory reset, press yes and yes again, and it will get you to custom recovery if you installed it.
4.2.1 If you factory reset your phone that means you didn't install recovery correctly and you will lose your data, but again that should be no problem since you have that backup from the start.
Now optional steps:
5. Install system app remover to remove bloatware from your phone. You can do it manually but this way you will have those apps backed up.
6. Next suggestion is to install a few mods if you need them. In my case I had to have a Plug and pop, since it is lost from Lollipop and I loved that feature. Here is a thread on how to install that mod by @p_a_r_s_a7
//That's all, if you have any questions feel free to ask, since there is no dumb questions, but also try to read carefully before//
Thanks to:
@quangnhut123
@avicohh
@p_a_r_s_a7
@bender_007
A lot of others whose names i can't remember. If anyone else needs to be mentioned PM me and i will add you in this section.
I will add pictures and stuff if needed
Thanks, good all-in-one thread, + easiest methods. Ill recommend it‚to others
This forum is such a mess that a thread like this is like a fresh breath of air. Every advice given on other threads references something that you should already know how it's done, or you should already have done to your phone in the past and have a certain version of it, or non-working tools that are only around for a few months until an update makes them unusable.
No wonder that most of the first-page topics, including pinned ones, have the word "brick" in the title. This should signal the forum moderators that something is wrong around here.
My phone is stock international sim-free G2, never rooted or otherwise modified and yet no one was able to offer a coherent solution of how to update to Lollipop, until your post.
So, thanks for this thread.
Thank you, that is exactly why i made the thread. Every one of those threads has everything explained, but you need to search theough 150 pages to understand how something is done. That's why i wanted to make a thread with all explanations made in a single post and to make it noob friendly since the worst thing that happens in other threads is answer like use a search you have it somewhere.
Hi,
Thanks for the thread. It really helps noobs like me, but I still have a couple of questions...
I was running Paranoid Android L rom with root, twrp and kk bootloader on My D802.
I didn't see this thread before I decided to downgrade back to 4.2.2 stock rom, and now I don't really know what steps to take.(I have kernel version 3..4.0 and build number JDQ39B)
I haven't seen an OTA available, so I was thinking of flashing new Lollipop rom kdz file. But I've been seeing stuff about using LG PC suite to upgrade via OTA so i wasn't sure.
So my main question is that do I do an OTA upgrade on my current 4.2.2 stock rom or do I download an official Lollipop rom? Can you give me a brief idea of the steps to take?
Thanks

Updating through pc suite or ota is the best way if it is available to you. Flashing kdz is the same thing but that is doing it manually while through pc auite nad ota is pretty much automatic. Anyways which ever way you decide to use be sure to fully charge your battery and factory reset acter the update. If you need anything else feel free to ask

No need to flash bootloader if you didnt flash it for paranoid android. And definitely no need to root since you can root after update.
Problems with flashing KDZ
I have downloaded Spain Lolipop KDZ file for LG G2 D802.
Have backed up everything usint TWRP> ( Presently on Optimus G3 rom v 1.4.1 with dorimanx kernel and TWRP )
I have copied the KDZ file to the flash tool. When i use CSE flash .. it takes me to the next page .. in which I click on Start which then opens up the LG Mobile support tool.
Then it shows detecting ur phone .. unpacking or extracting file .. after that shows software updating .. reaches 2 % and then shows error .. asks me to retry .
Do you know what I am doing wrong ? or the cause of this prob ?

Had the same problem when flashing kitkat kdz. Are you sure that you have pasted kdzfile inside flashtool. If that is not the problem try other kdz. That helped me
Where are you from and more specifically whhere your phone is from so i can maybe help you with finding right kdz. And btw i think you might have a problem when trying to restore that backup so if you still can backup your phone manually or on the cloud.

Hi again..
OTA update to Lollipop has failed on my D802, LG PC Suite only upgraded me from Android 4.2.2 to 4.4.2, so can anyone help me out here?
Am I missing something for OTA update? If not, then which lollipop kdz can I download for my phone so that I can flash? I live in UK and i use a 3 UK sim if that helps
but also, In the process of trying to boot into my previously installed TWRP recovery, I discovered that i have been restored to stock recovery. I have rooted the phone, but just wanted to clarify: I flash custom recovery, then bootloader/kernel then lollipop kdz?
Thanks again

I am not sure but i think that update for the uk didnt come out yet. so you can't update to lollipop yet via pc suite or ota. and you got it all wrong. first you flash lollipop kdz but you will have to try out few of them since official for uk didn't come out yet, after that you root, and then flash custom recovery.
and as previously you will be back to stock recovery after update. you have it all explained step by step in first post. i know it is a bit long but that is the best way, since i didn't want to write stuff like "you should know that" and so on. so just follow the first post and you will be happy, or wait for official uk update over the ota you will be happy too, and i guess it should come out in a month.

Thanks for the quick reply.
I'll download all the lollipop kdz's and see which one of them works for me till the UK one comes out then I'll just do a normal flash over it.
But seriously, one month for the UK ota :crying: Right now, I don't even know which is worse: Google that takes forever to release updates with so many bugs, or Apple who generally release better stable updates but make older devices laggy...
Thanks again for all the help.

its a good update, not that buggy, and be sure to fully charge your battery before the process. you should try europe open or something like that, but there is no german or uk release yet and some guys suspect it is slowed down because they found out bugs in other versions
After CSE Flashing my d802 with a 30a, it got stock on lg logo screen, then an android screen with "erasing" on bottom, then lg screen. I let it sit for 4 hrs but nothing happened. Im back to stock kitkat atm. A little help please.

Where from is your phone? Are you sure you flashed right kdz? Did lollipop even turn off? DidCSE flashing finished sucessfully? I would like to help you, but i cant if you dont explainme what is your problem. I am not some pro who faced every error on every phoneso please explain a bit more
And i suppose that erasing screen could have been factory reset on stock recovery

I believe mine is an international version. Where it came from, well, I'm from the Philippines and I got my phone from a local telecom, Globe.
The flash tool said that it was successfully upgraded, but judging from the phone's behavior I think there's something wrong. My phone never started successfully, and I got stuck in the LG logo.

Phone: LG P500h - ANDROID v 2.2.1 buildnumber FRG83.
Country: Brazil
Anyway, what I know is that i have to downgrade it to 2.2 in order to be able to root. I've looked through a bunch of tutorials on a bunch of websites but there are a few questions i have about the process that isn't answered anywhere i've looked.
Apparently downgrading requires me to get a stock ROM from LG, there is a topic here for that but it does not have the right ROM for my country, i tried a couple codes but they all got me 404.
Can I just flash any standard ROM from, US maybe, will it work?
And if yes, how do I flash it? Apparently you can do that by booting into recovery mode, but to get there you need it to be rooted which I can't do.
I've read about KDZ and downloaded that but... it crashes a lot in my PC (whenever i try the Read Device) it gives me error and closes the program (windows program not responding dialog).
I'm afraid it might crash in the middle of it if i try flashing and that would brick my device.
Is there a simple way to flash a new ROM? Is that the first thing I have to do in order to get a custom ROM say Ubuntdroid? It says I need a new recovery... but for that I need to downgrade first? It's a lot to do... and I don't really get the order in which I should do it all in...
Can somebody post me a little "do this, then do that, then finally do that" so that I can understand it all finally?
Thanks in advance, and sorry for long post, was trying to be as informative as possible.
This shows what happens when I try reading the phone on KDZ... also a little part showing that I got my device to be recognized by windows...
also disabled the LGE modem on device manager, read that if I don't it'll get bricked.
Well it won't let me link the image so... just paste the name together.

1. Find a suitable v2.2 stock ROM for flashing (link)
2. Use KDZ to flash it (I am not aware of another tool capable of doing that). Try doing that on a PC running Windows XP (important - that's where you're stuck now and I guess you're using Windows 7).
3. Root your phone - search for "z4root" on Market, install it.
4. Install Custom recovery, which will replace your current (stock) recovery mode (link - you may need to create an account on another forum in order to download).
5. Using Custom recovery you can now install any custom ROM and create nandroid backups to restore your phone to a certain (working) state.
You will have to use KDZ again if you ever want to flash a stock ROM, also losing the custom recovery. But you will have no reason to do that, except if you need to take your phone to some warranty repairs.
Good luck!
NEW PROBLEM: About step 1... i finally found a way to get my country's rom, but... it's.. the same thats on my device right now, it says V10a_02 and thats the same on my phone (the kdz read phone tells me that) so... won't I just be flashing the same 2.2.1 again?
http://csmg.lgmobile.com:9002/swdata/WEBSW/LGP500H/ABRABK/V10A_02/V10A_02.kdz <---- the rom the topic tells me to get.
How do I know what version of android is in that rom? and if i can't, can you link me to a rom that does?
I found one from another country that the guy said is 2.2... but... will it work if i flash that one? does it HAVE to be for my country? also my model is p500h (the h) is it different from the p500 (different as in flashing p500 without h roms on it will kill it?)
As for flashing it...
I think maybe a computer with win xp will do the trick for kdz.
i've found this post today:
http://forum.xda-developers.com/showthread.php?t=944881
is it better to use that than kdz? theres no replies on topic saying "hey it worked" so i'm a little worried, but apart from a few errors it seems to work on my win 7....
i guess the reply would be "i only know kdz, do it with kdz" but i thought i might ask...
Indeed, I have not tried that method and therefore I can't recommend it. At least KDZ is successfully tested. If you are patient enough to wait for some replies either here or in that topic, you may find out if it works. I would recommend it only if you have no other choice, like if you're unable to try KDZ on an XP machine.
In the mean time, I remembered that a newer version of Custom recovery is available (v1.2) - here. But you still need to download a file and read the tutorial from that other forum I mentioned in the previous post.
what about the first part of the post? i think i might have added that after you replied i don't know... asking about the rom i found if it isn't the same i have on my phone. and asking if i can just add another country's one...

First backup your data, then download a factory ROM, it doesn't matter which version u download, what matters is the version. Make sure that it's 2.2 and not 2.2.1 or 2.2.2. Follow all the below steps without skippin any, no matter how simple or stupid they are.
Link for shipped ROM - http://forum.xda-developers.com/showthread.php?t=865479
Now download KDZ updater and uncompress it
http://www.4shared.com/file/UleS4dP3/KDZ_FW_UPD_EN.html
Install msxml.msi from the uncompressed directory
Charge your battery to almost full state (I'm not sure, but it can be reason if phone doesn't start)
Turn phone off somehow (remove battery etc.)
Install drivers properly
Get rid of all usb drivers like Nokia, microsoft visual ++ run time environments
Install the LG drivers by selecting the update manager from the lg site
Disable LGE Virtual Modem. In your Windows operating system, go to Control Panel > System > Hardware > Device Manager > Modems > Right click on LGE Virtual Modem and click Disable.
Press and keep pressed "Volume up"+"Return" and connect USB cable to phone
Yellow screen with text emergency mode should appeared
Shake the handset (I know, it sounds ... strange, but it helps for ones, so... why don't try it?) UPDATE: Read some quotes on bottom.
Run KDZ_FW_UPD.exe (Has administrator).
Select Type : 3GQCT (I have one report that CDMA mod works too)
Select PhoneMode : DIAG (in case of fail try EMERGENCY, and as last chance use CS_EMERGENCY)
I Recommend do not switch phone off. There was some people, which done it and after they was not be able to turn it on again. If flashing failed, just select some another mode and try it again, again, try shake/connect disconnect, again, again....
In KDZ file : Choose the ROM file you downloaded in the first step
Press Launch software update
Shake the handset (I know, it sounds ... strange, but it helps for ones, so... why don't try it?) UPDATE: Read some quotes on bottom.
Now Root it via Z4root - http://forum.xda-developers.com/showthread.php?t=833953
Then install custom recovery - http://forum.xda-developers.com/showthread.php?t=844483
Then download n flash any ROM of your choice, I wud sugget install Void or LOL.
Edit :- By the time I replied, many have already replied. Anyways you can check my reply too :-D

"it doesn't matter which version u download, what matters is the version."
does that mean it doesn't matter what country or operator the rom is for, as long as it is android version 2.2?
i have one from portugal (not my country) and that one is made for P500 mine is P500H... if that makes a difference i don't know, but i do know that rom is android 2.2. can i flash that one?
i also have one that i got from that topic following the instructions of putting my serial number, it linked me to a rom V10A_02... on KDZ when i try to read my device it says i have V10A_02 too. isn't that the same one i have now? with android 2.2.1? if it is it's very pointless to flash the same rom already in it.
any way to check?
because that is my last doubt ;p

Yes.... you can choose any country. I tried the Australian version. Use the below one http://csmg.lgmobile.com:9002/swdata/WEBSW/LGP500/AAUSBK/V10a_00/V10A_00.kdz

As far as my knowledge goes, the LG P500h you have is the same phone as the P500, only branded for Telus. The hardware should be identical, therefore you may use any ROM designed for the P500 family.
The only thing you may miss if you install a ROM not customized for a Brasil (or South America) network operator is the internet acces point name, thus rendering your phone unable to acces the internet trough its data service connection, but only trough WiFi. Nevertheless, the phone's APN can be configured manually, all you need are the correct settings from your mobile operator and you're good to go.
Ok since you guys told me i can go ahead and flash any country ROM i just did and now my device burst into flames and then the flames consumed my apartment.
ok, not. it worked too well actually, i did the kdz procedure on my win 7 anyway, despite the errors when reading device info, and it took like, 1 minute, rebooted, took like 2 minutes on the android screen then it came back, with all my data still there... i thought it didn't do anything but... its now version 2.2
i tried z4root, worked ... got the superuser app and.... i'm happy ^^ thaaaanks!
anyway about the custom recovery thing..
i'm going to install the one in that post you gave me...
but i read something about the best one being clockwork something...
shouldn't i go ahead and install that one?
or can i do everything i need with this one you guys linked?

Glad that it worked Install the Amon_RA's recovery!!! Many ROM's for OO won't support clock work I suppose. Amon RA's recovery is neat, I've been using that from the time I had an HTC tattoo.

You can do anything you need with ThunderG. Now that version 1.2 supports backup and restore of ext4 partitons (a feature you don't need if you don't plan on installing a custom ROM... but you will, eventually ), it is complete.
Moreover, in ClockworkMod's first topic says: "This recovery will not allow you to flash every ZIP file". ThunderG does, if you choose to allow flashing of unsigned zip files. Sometimes this is useful.
Peeeeeerfect
Recovery installed, LOL ROM installed, all fast smooth and error-free.
no more screen touch lag, it's soooooo much faster now, overclocked, i have yet to test my emulators but i can only guess they're gonna be at least 150% better lol.
thank you all very much for taking the time to help me ^^
ONE LAST QUESTION: I PLAN ON BUYING A NEW SD CARD, JUST PLUG IT IN AND IT'LL FORMAT THEN CREATE THE NEEDED FILES THEN I INSTALL STUFF BACK ON IT, SIMPLE AS THAT?
Simple as that =D
Although there are some criteria with the sd card or you'll get unmounting problems.
Use a class 4 or higher card
format with fat32
I've never officially tried this method but its apparently supposed to help
allocation unit size: 64kb when you're formatting

Any idea?!
== Updated
Ok, I´ve flashd it with KDZ and the log show´s thats all ok
"14:34:45 : ===FINISHED=== "
BUt its taking like FOREVER to start... almost 30min on android screen. Is this normal?! Should i restart the phone?!
leave it some more time , try shaking it ...
shake trick sometimes helps
Help please..
I did as instructed in the step to step procedures. kdz posted finished but my phone is still at the yellow screen..i did shaking but nothing happens..Is this normal?..SHould i wait..
Chapter 1: The Foolishness of the User
Hi, I have the korean version of the optimus one(KU3700). It was on gingerbread(2.3.4) stock. I was trying to root it by downgrading it. I entered "adb reboot recovery" and I'm stuck. I tried to reflash it by going to emergency mode with the button combinations using the KDZ updater with this
"csmg. lgmobile. com:9002/swdata/WEBSW/LGKU3700/AKTFBK/KU370040_00/KU370040_00.kdz"
and it worked without any errors but when it when it came up it was still on recovery mode. Is there any way I can change the phone mode to the regular mode
Chapter 2: Journey to Salvation
For anyone who has this korean optimus one, after days of searching, I've found a web site that gave me hints to solve the problem. I just needed a different kdz file and I got it here:
h t t p://sirospace.tistory.com/category/Android%E2%97%86
popped it in google translate because I'm Filipino and can't read korean.
Downloaded the froyo kdz and flashed. I hope this can help other people stupid enough to play with their phones by typing random commands without knowing what it does, like me, LOL...so happy, now it's time to root
Chapter 3: False Hope
OK so I have successfully unbricked and rooted my KU3700, now The problem I have is installing a custom recovery on this phone, none of the images I try work.
Recovery images I have tried are as follows:
recovery-RA-GNM-thunderg-1.1.0.img
recovery-RA-GNM-thunderg-2.2.1.img
recovery-RA-GNM-thunderg-3.0.6.img
Every time it finishes and reboots, it gets stuck at the LG logo.
Chapter 4: Wisdom Within
Found the problem. The images above are for the P500.Even if the KU3700 hardware is similar to the P500, flashing firmwares made for the other model will result in errors. The same holds true for custom recoveries.
Chapter 5: The Plea to the Gods
I've contacted drellisdee and submitted the files needed for custom recovery creation for the KU3700.
Just waiting for the flash image now. Thank you everyone
Chapter 6: The Forgotten
It seems drellisdee is busy right now. I'm a windows user and knows nothing about programing. So if anybody can help I'm sure the KU3700 community would be greatful. I've attached the files I think are needed to make a custom recovery.
Chapter 7: Quest for the Custom Recovery
I got tired of waiting. So as a windows user with no experience in programming, I did a lot of copying and pasting, I managed to port clockwork mod using virtualbox following this website:
h t t p://www.koushikdutta.com/2010/10/porting-clockwork-recovery-to-new.html
So I have got a bootable and flashable custom recovery but nothing works yet. I still need to configure it according to the device.
I have uploaded the image and the build files. Please help me configure it and tell me what's wrong. I really don't know that I'm doing
PS: you can try flashing the custom recovery by doing "fastboot flash recovery /Path to/recovery.img and you can go to recovery by using android terminal and type "boot recovery". It will boot, but that's that LOL. Take out the battery to boot to normal mode.
Chapter 8: The Holy Grail
LOL, I found the answer again. I was so frustrated that I kept squishing the phone in recovery and found out that it was just a button configuration problem. A bit of research and I found out that I can toggle it by pressing volume up and volume down at the same time. WOOHOO!!! Custom Recovery at last
Chapter 9: Invasion of the ROMS
And here at last, the user is retired. But the adventure is far from over. It is foretold that the creation of the Custom Recovery will begin a new era. The key to open the gate has been found. So our hero will await the invasion of the ROMS<background music...> END

Thank you for the reply but as I said, I can flash fine without errors it's getting back to regular mode I have a problem with. Rebooting and reflashing does not take me out of the recovery screen(it's just a opened box with an orange arrow and the android logo).

This is just a shot in the dark because i didn't understand what you did entirely : have you used the combination to actually recover the stock rom after you flashed with KDZ ? (Home+VolDown+Power)
Yes already did. The computer can see the phone whenever I connect it except that I can't access adb. I may have to take this back to the store

Are you sure you flashed the right rom for your phone? There's an application that downloads the required rom for your phone according to your IMEI/SN, but i don't know if it works with the korean version.
Yes it's the KDZ file, unfortunately it's the only KDZ file out there for ku3700. Shouldn't have settled for this korean version
why you wanna downgrade the latest version?
Dude I have the same Korean edition as you.
Actually why you wanna downgrade the latest version.?
My phone had 2.2.2 and I did upgrade it into 2.3.4 I did it officially and I can tell you How to re-install 2.3.4 if you want.

Thanks for the reply. I wanted to downgrade it to root it. And now I'm rooted. My only problem now is installing a custom recovery. I've already tried several custom recoveries:
recovery-RA-GNM-thunderg-1.1.0.img
recovery-RA-GNM-thunderg-2.2.1.img
recovery-RA-GNM-thunderg-3.0.6.img
but I get stuck at the LG logo when it reboots. I think it's because it's for the p500. So if you have a custom recovery for the ku3700 please help
I dont get it ,p504,p505,p506 are versions of p500??? And why some of our roms work on those phones?? So by logic this stock work on p500???

this method worked for my working KU3700 when I'm using my 1st KU3700 I also was struck as you and finely I realized there are No custom roms for Optimus one Korean edition (KU3700/SU370) and I had to connect my phone to an Octopus box (lg softwere box) via software box installed the official firmware. if this method not working you have to connect to a software box.
connect to the internet your PC and 1st install Driver and 2nd install the LG update tool. after installation connect your phone to computer and wait a five seconds for comport installation. after install your phone Run LG Update application.
it is connect to the server automatically indicating red line and after search for latest firmware.
if you can Update your phone it is shows Update butten.
Driver

LG Update Tool

Thank you all for the quick answers, but I already have a rooted ku3700. All I need now is a working custom recovery. If someone has the same phone, please tell me which image is compatible
you can appear the emergency mood with android logo.
it means you have an Empty phone. your Os was been erased. You have to connect your phone to Octopus software box and box server has you original Os for your IMEI. this is the only solution. if you will able to solve this problem without a Software box please inform me. we can open a New Thread for Korean edition.
(ku3700/su370)
I already got out of the emergency mode without an octobus box. It's really simple, you just need to use a different kdz file. The hard part was looking for the kdz file. I have 3 kdz files. KU370017(froyo), KU370033(gingerbread-rootable), KU370040(latest one from LG, gingerbread-unable to root). Just flash with the KDZ updater. I'm on the second firmware because I can't root the latest firmware. To root it, I used super one click(latest version, use zerg rush option). Now I'm just waiting for a custom recovery from drellisdee so I can use custom roms. When I get it, I'll ask him if I can post it so we all can have uber phones LOL

If you have flashed a working clockworkmod you can enter into clockworkmod via ROMManager (search in google play aka market). In ROMManager you have "reboot to recovery" option in case you want to go to recovery to flash something. Also you can try to flash from ROMManager a custom recovery (5.0.2.0 for oldBB or 5.0.2.7 for newBB), try to choose to phone model LGP500 oldBB, try and test if it's working. Wish you luck.
Thanks but I already have a working recovery. I just need some ROM makers now

Have you tried CM7.2? if your phone is very similar with Optimus One i doubt it isn't compatible with your phone.
If your phone use 2.6.35.10 or 2.6.35.14 kernel you can give a shot to try CM7.2 on your phone, but before try this make a backup first.
Check this thread Post Your CyanogenMod 7.2.0-RC1 Nightly Questions HERE!! for CM7 custom rom.
yep, it doesn't work. Is there a tutorial for building cyanogen for unsupported devices? All I can find are tutorials for supported devices. I've already got the source code from LG. The problem is just incorporating it in the cyanogen mod. I wish this phone had more users LOL
I have the Verizon LG G3 with build 12b installed (Was updated by the store when I purchased phone). Is there anyway to unlock the boot loader and root the device as is, or roll the device back to a previous build that is easily unlockable/rootable?
You should have posted in the q&a forum area.
Anyhow - if you want to root, and install a custom recovery (twrp), use the kdz method to get back to 10b:
http://forum.xda-developers.com/showthread.php?p=56484240
Then from this forum area install the bump/twrp from autoprime, and make sure to either freeze system updates or rename the two LGDMSClient files in /system/app. The freeze or rename is so new ota don't get pushed onto your phone after you get the custom recovery (twrp). Otherwise you'll needed the solution in the "stuck in custom recovery" thread:
http://forum.xda-developers.com/showthread.php?p=56061720
(It is handy to download the "stuck" zip onto your phone as a just-in-case. If you do get an ota, and your phone keeps booting to recovery, tell twrp to Install the zip to clear the ota files )
HTH!
I am trying that method now (actually before you replied) but the kdz file is taking for ever to download. Been running for 30 minutes and still showing 7 hours remaining. I have a really fast internet connection but that one file doesn't wanna download!

I think I am in love with you, JK.....seriously though thanks a bunch....downloading the Mega link now and it seems to be going MUCH faster.
Did it work for you? I tried to downgrade, when phone said 100% it rebooted. I had a dark screen.... Went to the Verizon store, was told it was hard bricked. Haven't tried rooting my replacement yet.
Early adopter, got my phone in July, used the original ioroot, never had to revert.
The kdz method has had quite a few people who succeeded, based on what I read, no idea why it went bad for you. If you are gun shy, understandable, post 2 of annoying duck's thread has a link for the tot approach, supposed to be a slightly more pita way but not too exotic. Key is to flash any existing g3 drivers on your PC, install the proper things used by the tot method.

Recently I Rooted My Sprint G3 Lolipop. Had no Issues there. Then I wanted to install TWRP, So I downloaded AutoRec, waited for the app to confirm everything and installed it. When I turned my phone off and tried to reboot into recovery, it Gives me a screen that has the LG Logo and it says Security Error and turns back off. I can still go into download mode but thats all I can do.
Ive read the other posts for this problem but i havent found one for my specific Phone.
Can anybody please help me with step by step Instructions?? Im still not super expirenced in rooting phones and the other phones I have rooted have always been successful..
Sprint LG G3 5.0.1
LS990ZVC
Heres a link to that same problem. The member experiencing the issue fixed it by flashing a .tot file from a previous ZV version he went from ZVA to ZV4 u should be able to do that i believe by using the 2014 lg flash tool, look it up. While i dont like flashing different ZV versions myself i think u might be safe for the most part.
Me personally think but might be wrong so dont quote me.. Lol but i would flash using a ZVB tot/kdz in the 2014 flash tool and i believe the lg support tool will then upgrade u back to ZVC if not the LGUPtool i mean your taking it from a noob but i think i stand correct here lol

Thanks. Actually didn't even waste my time on it. I still flash and do everything else with my phone. Found out it was a authentication code or something like that. Thanks for the reply back though!!!
Dear XDA,
I've rooted my LG-H850 some months ago. After some time i decided to update my phone to a new rom and saw that Nougat finally came out for the LG G5.
Now i'm reading the topic from Fulmics 1.0 and saw the following : '''Just flash in TWRP recovery after performing necessary wipes. Be aware that you have to be on Nougat bootloader, so make sure to have installed official nougat KDZ first.'.
I did some reading around on XDA but is still leaves me with some questions and i hope i can get some information about it.
People are talking about LG Bridge.
I haven't checked this out so far. My phone has TWRP and a custom rom on it.
If it's possible to update my phone, is it safe to do it this way?
Also i've seen people talking about a KDZ file. It has been a while since i rooted my phone and if i remember correctly you needed to use the KDZ to get TWRP on it. Correct me if i'm wrong.
If i install this KDZ file, am i ready to go and flash the Fulmics rom?
And if this is so, where can i find this file?
Sorry for the noobish questions but i reallly want to safely update my phone.
Thank you for reading!
With kind regards,
MarshalSmit

Thank you for your reply. I totally forgot to mention i have an LG-H850. Does this works for the H850 as well?
Anyone that can help me ?
I also have H850. I was rooted on MM. All I did was flash N KDZ with LGUP. Then I falshed TWRP (N version). Then I Flashed SuperSU (N version) from TWRP. For now I'm using rooted LG stock (N). I honestly don't see the point of custom ROM for now...it works great, smooth, battery life is good (approx the same as on MM).
I've done everything you have said and the phone worked perfectly with SU and all.
After that i installed Fulmics on it. After i restarted my phone it gave me an message that the phone encription had failed and that i needed to reset the phone. With my stupid head i pressed on this button.
Currently i'm getting instantly booted to TWRP and that's it.
Did i just fully bricked my phone?
// Starting the phone connected to a charger fixed it for some reason .
