Hello guys,
I am new to android and xda. Recently I got unlocked At&t Optimus G E970. I rooted the device and then froze all the At&t bloatware and also some google apps. After restarting the phone it is showing 'Security Error' on boot screen. So I was searching for a fix on it and found this,
http://forum.xda-developers.com/showthread.php?t=2010624
I can get the phone in download mode but how to download the KDZ file? I am using the software in the above thread for downloading the KDZ but its not working. Please help!!

You need to use a program called LGNPST to recover. Go to this link and study the section in "additional info" about LGNPST. In your case the teenybin files would only be helpful if you wish to flash a custom ROM , but the same process can be used with files for stock firmware.

Your welcome, let me know if you have any problems.
Also should mention that unlocking boot loader with FreeGee app will disable security check.

Got an optimus g off CL. The guy didnt tell me he converted it to mako (thats what it says on fastboot screen) I am trying to get it into recovery mode after I flashed a non mako rom on it. It won't work. So I figured I would lgnpst it. That wont recognize the phone. I'm on windows 8. Is there a special way I have to enter recovery now that it was converted to mako?

Install Proper Drivers And Try To Boot In Download Mode And Usr LGNPST To Flash Stock .tot File.
Teenybins Are Excellent To Recover From A Softbrick,But If You Are Using A N4 Converted G Then You Will Have To Restock First.

If your boot loader is unlocked it will say mako, doesn't have to be converted to say that. Which splash screen did it have when it first boots? If it shows LG for a second or so it is not converted. You may just not have updated rpm/tz partitions needed for 4.2 ROMs. Also lgnpst won't work with USB 3.0 for some reason, and your phone needs to be in download mode for lgnpst to work.
Thanks for the fast reply guys. It was on a usb 3. Got back into cwm and restored it. Will attempt to flash the ota firmware but LGNPST can find the .dll file. I have no idea where it is.

If you use tSilenzio's automated lgnpst it registers DLL for you, it will say ls970 but it works fine for e970, click on the little folder icon in lgnpst.
Edit...is your phone converted?
No it is def not converted. Thanks again guys!

If you are certain it is not converted then you can use teenybin file with lgnpst. It updates your partition and installs twrp. You would just need to flash your rom afterwards and be done.http://forum.xda-developers.com/showthread.php?t=2230994

Be Sure With It.Because If You Flash Teenybins On A N4 Converted Phone,It Will Hard Brick [Only Way To Recover Is Jtag]

Not sure what would cause that error. Automated lgnpst wasn't out when I installed it on my laptop, and teenybin wasn't out when I updated to 20j. I always selected dll first then bin. You may want to ask for help in the irc channel http://webchat.freenode.net/?channels=lg-optimus-g
got the dll but now it's giving me some error. something about version number 501 or 503...I'll get back on it tomorow.

[Q] Need help unbricking my att e970

So I rooted my att Lg-e970, and things were running great. But then I deleted the google books, and google movies, and then I rebooted it. Now when it tries to reboot I get security error. I can get to the factory hard reset but it says secure booting error Cause: boot certification verify. I cant get it into fast boot, only download mode. I downloaded LG KDZ updater but I am unable to find a firmware file. I tried Original LG FIRMWARE, but it never works for my phone and IMEI. I have tried a few, and searched, and pretty much frustrated right now! lol
So any help would be great!
Thanks in advance!!!
You need to use lgnpst and restore your phone. That will get you back to normal. It's happened to some people in here so you aren't the first.

Here is firmware link. Go to teenybin thread in android development for links and guide for lgnpst. If you want to delete bloatware you must unlock bootloader, use freegee app from playstore.

Well if your phone isn't bricked (meaning you can boot it up to the home screen), you may flash the entire JB zip located here: http://forum.xda-developers.com/showthread.php?t=2067871
This is safer then using the LGNPST which is mainly if your phone is bricked.
But you did not mention that your phone is bricked, meaning you cannot turn it on past the boot logo.

As bricked as it can Get...please I need help!

Hey guys,
I'll keep this short but first of all I would like to thank all the people that make this website what it is!
I have always come here for help in the past but this time I am really screwed.
I tried installing a rooted TOT file using LGUP (a 20j file), and I forgot to do OEM UNLOCK before hand. Also, my phone was on 20L so I think I screwed up there anyways.
My phone boots up and gives me the "fail root verification" error in red and just goes on an endless bootloop.
At this point and after looking online for almost 2 hours I think the only two solutions would be to find a TOT file that works with my phone (H901) or the KDZ file that is from the latest update 20L. I have tried using a kdz file from the 20e update (first MM 6.0 update), but it says that antirollback will not allow to go back to a "smaller" firmware.
The files on this thread below are dead otherwise I would not be here asking:
https://forum.xda-developers.com/tmobile-lg-v10/development/rom-v20e-6-0-t-mobile-t3356412
Please can someone reupload the kdz file for the 20L update? or a tot file that would work on my case?
Thank you so much in advance!

lg logo infinite boot state. Help me

I was cleaning up the carrier file while cleaning up with "adb_appcontrol".
The apk is all backed up.
It is in infinite booting state in the lg logo.
fastboot- ok
QFIL-ok
Download mode-ok
It is possible. a001lg (Japanese version of lg v60) cannot obtain kdz.
That's why you can't put kdz back in using lgup.
Is there any way to restore this device? Please help me.

Can you try to factory reset it somehow? A factory reset would restore deleted apps.
If you relock or unlock the bootloader i think that will automatically factory reset.

I tried to reset the factory, but I only saw the LG logo for 30 minutes. Reset did not proceed and failed.
The bootloader is unlocked. The factory reset has already failed, so I can't try because I think I might fail even if I play.

I don't know if this will help.
I remember that it was restored a long time ago and solved by switching to a->b.
I remember switching from partition a to partition b using twrp in xda at that time.
Please refer to the link. One of the ways to switch partitions.

The Japanese version is managed by softbank docomo, not by LG, so they keep the kdz private.
It will be possible to change the slot without unlocking the bootloader. I wish you success.
