[Q] Stuck on LG Security Error bootscreen

Rooted my Optimus G and uninstalled Google Books and Google Music and when I rebooted I'm greeted with the LG Security Error screen. Tried the factory reset but that doesn't fix it. Am I screwed or can it be fixed? If so, how?
Thanks

I googled your problem. It looks like LG is rather dickish about debloating.
You might have to wait until some brick fix via ODIN is out

Maybe its possible for you to re-install the .apk's using push from adb...

download & install latest usb driver
download & insatall LG Mobile Support Tool
remove the battery from the phone
while pressing volume down button connect the usb cable and wait (about 10 seconds) in this mobe until SW upgarde is displayed on the phone
insert the battery back
perform a SW update via LG Mobile Support Tool
I don't have the optimus G but this helped me with other lg phone ; maybe will help you also
If the above metod don't work they are also other metods to try

Did you freeze the apps or totally uninstall them?

My guess is uninstalled with root explorer because when he factory reset it should of repushed them if they were still on the system.

Yeah, I uninstalled them. I also tried the LG Mobile Support Tool, all a no go. Sucks, I really like the phone, more so than my Galaxy S3. Just have to be patient and hope a someone finds a solution.

Go to AT&T and replace it lol still got 14 days

Can you access adb?

Couldn't access adb either after this happened, could before. I did solve the problem although I feel a little guilty how I did it since I know it is totally my fault. I returned it, said I was using the LG update software on my desktop and said it got half through the update and our power went out and it wouldn't boot after that. If the earlier post hadn't reminded me that AT&T no longer has a 30 return I would have waited it out in hopes of a solution, but I'm going on a business trip and won't be back before the 14 days are up. Thanks for all the help and ideas, this time I'll just remove the AT&T crap and not any Google stuff.

I have everything just frozen and no issue for me just dont remove anything as it might cause Software issues

if it was me I'd unscrew the back and take it out as long as it is not marked by a sticker or something it shouldn't void the warranty
read thoroughly " I WOULD DO IT" it's not a suggestion for anyone to do it, I'm just saying what's on my mind

I can verify that freezing, with TB, certain DRM-related apps will cause this problem too.
Sprint doesn't have the images from LG required to restore the device yet, and the guy at the store tried to take it apart to get the battery out so now all the glue is unstuck from the back glass and it's squeaky. I'm waiting on a replacement from them now. :-|

From what I saw of the Sprint guy's efforts they filled the thing with glue. I guess that's why it feels so solid

Another victim of this problem here. Any help would be appreciated. I was able to get to recovery menu from the phone, but not much can be done in there at this point.

Hop on the IRC freenode #lg-optimus-g we'll help u out!

Hello, I could not install anything, you can only enter TWRP, and have nothing in memory, as can be done to install a rom Stock?

As far as I know .tot.files are only available for at&t models.
For other g-pro models, there are no freely available flashtools.
"lg support tool" (with the .kdz.loader "uptest.exe") seems only to be safe with a locked bootloader on the phone.
Would be nice to make sure g-pro owners get to know that, before they have costly experiences with their phones.

what is going on here?
amilio just told us he isn`t able to flash!
already starting this thread with the misleading information!
this really gets down here to pure spamming!
why are you doing this???
nevertheless trying to give an answer:
TWRP has traditionally among its advanced tab features some sort of "adb" support.
on my other older android phone i could easily push zip files from pc to the phone.
This might be a way to go to get something to the phone that boots up or is close enough to stock firmware to be flashable with lg-support-tool

hello
thank you all, but I could not solve the problem, low battery error, and only enters TWPR, and I tried installing the CM, and error, which can not do.
thanks

cant you enter download mode? can you open your phone? maybe your file is broken. tried testing the archives using 7-zip it should not have any errors. if there is a single error , redownload it. that's what i when i flash g2 v5. i always get error status 1 but i fix it by redownloading and test if it has no errors in 7-zip. hope this helps

Before I created this thread here, I had already tried everything you have mentioned in your original post instructions. The instructions you provided are the first things I tried when I was troubleshooting and everyone should have already tried doing the obvious already. The problem most of us are facing, goes well beyond these instructions. I think it has something to do with missing boot files or permissions that were only exposed after the unlocking process using a specific released version of freegee.
I have managed to use LG Flash Tools now, even after being affected. I would not advise trying this though, as it was an accident for me. I had the back cover off while flashing a custom rom with CWM. After the rom file was installed, I rebooted my phone from CWM. As the phone was rebooting (was on the rom boot animation) the battery fell out. After I put the battery back in the phone would load to the rom boot animation, but it would freeze on this screen and then reboot and do the same thing over and over (bootloop to animation) - I then tried to factory reset and flash the rom again, with the same thing happening again) - I then went in to restore my phone using a backup through CWM. After the restoration, then phone would still hang at boot animation and then bootloop. I retried restoring and flashing multiple roms and re root the phone with a saved zip file on my phone. None of this was working. I decided to try to use LG Flast Tools again, only this time it actually passed the low battery warning. The funny thing is, I have tried thousands of times even at 100% battery level and lower (when there was nothing wrong with my phone at all) and it has never worked. This time it did (even though I had 66% battery) and still works now, as I just tried it again.

Thank you!!

LG G3 5.0 Problems

Hello guys.
I have LG G3 5.0 V20-i-TWN-XX
I have a lot of problems with the phone.
I get every couple of minutes a message says: unfortunately the home has stopped and unfortunately ui system has stopped.
Also the battery drains very fast.
I understood that there are a lot of prbolems with the lolipop 5.0 so I want to downgrade to 4.4.2 which doesn't have all these prbolems.
Can someone please send me a guide for this?
I mentioned above the version of my phone.
Just to be clear I live in Israel if it has any mean for the guide you will give me.
Thanks in advance!

The problems you have are not normal. Maybe an application or settings issue.
Have you tried to a hard reset? (Back to factory settings)
Alternatively you can try a custom Rom. I'm on cloudy and it is rock solid. You need to root and install TWRP.
