I recently purchased a LG Optimus G and started installing programs on it. once it got late I plugged it in to my computer (to charge it) and out of habit, i restarted the phone. It got stuck on the LG logo and kept saying Security Error...thats it...no number or any other explanation. I did a hard reset and nothing happened. I NEED INDEPT INSTRUCTIONS ON HOW TO RETURN IT TO WORKING CONDITION. I spent all night reading other post and devs or other users gave vague answers like "oh download this..." with no link....or use this with dead links.....PLEASE HELP THIS LG NOOB. .
The security error is from uninstalling bloat without having bootloader unlocked. You will need to restore using a program called lgnpst with stock firmware. Found here http://forum.xda-developers.com/showthread.php?t=2219953&highlight=jellybean . Links for lgnpst can be found here in teenybin thread ( you may also use teenbin files in place of stock firmware if you want to install custom ROM, it will unlock bootloader and install twrp recovery) http://forum.xda-developers.com/showthread.php?t=2230994 . If you decide to install custom ROM it will need to be on SD card so it will be available in recovery.
Edit... Be certain you have AT&T LG E970 model before attempting this, if you have any other model you will need to use different files.

Hello. This is my first time actually visiting the Optimus One forum although I have had my phone for maybe 2 months. I was not going to root my phone, in case I need warranty, so I was using the stock rom, although it was a little slow.
So I thought MAYBE there is an update on LG website, so I went on there, and found out that I can update by connecting to the computer. So I did download all the files they required (at least I think I did), and I followed the instruction, and started updating. Here comes the first problem encountered: While the phone was n Emergency mode, during the updating was in process, it said Phone and PC has problem communicating or something like that. And there was a restart button. It said disconnect the phone, and remove battery and connect again, and then press restart. So I did. Then now after that the LG software update tool doesn't recognize the phone. It said connect it and press OK or something. I think this is the point where I bricked my phone. A NON rooted phone. So I don't even have a custom recovery to flash anything! I hate LG right now. They are so stupid. I don't know what happened..
I tried the method here:
http://androidforums.com/optimus-one-support-troubleshooting/237642-bricked-lg-optimus-one-help.html
But I couldn't download the right KDZ firmware for my phone, that is available in the link in that link above. I'm in Canada and my phone is from Koodo and the model name is P500H.
So I got a random KDZ file that's for P500 from internet, but the in the KDZ_FW_UPD emulator, that's in the link above, it says my phone is NOT detected! I reconnect the phone and restarted the software so many times. I think they want me to connect the phone while it's Turned ON, and press the "Connect to USB" button. I'm not sure though.
***PLEASE*** Help me! I really need to unbrick this..
Sorry for the long post. And Thank you!

Thank you SO much for your reply. I was searching for HOURS, and Finally found out how to make the KDZ update tool recognize my device. A LOT of people can't get it to work, but I saw someone in this post http://forum.xda-developers.com/showthread.php?t=1015332&page=4
that you need to remove sim card and battery. So I did, and restarted the update, and YES! It worked! I was on Foryo, but I got Gingerbread Rom from
this forum http://mobilesyrup.com/forum/showthread.php?t=21446&page=2
And I'm actually on GB now!
OMG, I have so much homework, but have been doing this for the WHOLE day! Wow..
Thank you so much for your help anyway!
Oh thanks

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!!!
I recently rooted my lg fortune 2 by installing the lg aristo 2 twrp file and magisk. This was my first rooted device so I was surprised at my success but being new at this it didn't take me long to attempt to use a module from magisk that encrypted my device. I hadn't flashed a no verify opt zip because i didn't know i needed to lol. So me being a novice i ended up wiping-deleting my os in twrp while trying to fix it. Since i bricked my device iv'e tried to install factory lg firmware using lg bridge,lg mobile support tool and the lg flash tool for flashing kdz files but they always fail at 5% installation with a contact your local admin screen when it fails. Is it possible to flash stock firmware for cricket devices or could i somehow turn a kdz file into a zip file i could install via twrp. I also haven't had any luck finding a tot file for my device either.
Fortune 2 help!
Hi,
My lg fortune 2 lm-x210cm10o is being a pain. If you wouldn't mind too much, I would like to know where you got your root method from. It's been two weeks of failed attempts and to be honest I was just about to throw the same thing out the window. I mean that literally. So, to prevent such a catastrophic tragedy, could use a little help.
Thanx if you can or cant,
Matthew
