Hey XDA.
Before you asked, yes, I used the search tool.
I'm having trouble recovering my D800 LG G2 from being a brick. The situation is, I was running the Euphoria 5.1.1 rom, with TWRP and root status. I went to reset the phone through the settings, which began my list of problems. While it was rebooting, it kept flashing the TWRP splashscreen, and I had to turn it off and go into the recovery manually. *NOTE* at this point, the phone was not reset, it's almost as if I just turned it off and on. I went into TWRP, and wiped the phone. I think this is where I made the mistake. I did an advanced wipe and wiped everything but internal storage, instead of just doing a regular wipe, because I'm a dumbass. So now, My phone is stuck on the LG logo when I turn it on, followed by a black screen. The usual unbrick methods aren't working because my download mode is not working. When I try to go into download mode, the main window on the phone pops up, but a window on the top left saying "security boot error". My computer will recognize it, but nothing will show up in the port, and I'll only see the qhusb_bulk in the other devices.
I have no idea what to do, and I would really love some help and suggestions.

Can you get into download mode? if so just reflash stock.
sorry, i can't put a link here because i don't have 10 posts, but if you tipe in youtube search ''How to Unbrick or Restore the LG G2 ATT Version'' you will get a rootjunky video which helped me to unbrick my phone and back to stock rom. There you will also find some usefull links.
If you can get into download mode this will save you each time. I have had to flash mine a few times while soft bricking it. Its mega fun when you hard brick it. Good luck.

Hello, I went through Rom Manager to upgrade to the latest CM, I opted to clear the dalvik-cache, and clear data but didn't back up (I have other backups). It started going through the process, then the phone seemed to reset as if it was done installing and rebooted, It hung there for a long time (15+minutes), then the screen went blank, no lights/no response. I tried to restart the phone, it now stays at the google screen, so I tried going into recovery to flash a previous back up, IT WONT LET ME, the screen just goes blank and the lights at the bottom go on. When I go into fastboot mode it tells me my phone is locked again! And when I try and access fastboot through my pc it wont even read the device..Please help me..factory reset, I don't care..someone please help, what can I do?
Did you have fastboot working on that PC before? I.e. are you sure you have sdk/drivers correctly installed?

Hello everyone. I recently just recieved my ATT LG G2 in the mail, and since I really didn't like the OS it had I wanted to root it. Anyway, I rooted it, installed twrp, and i tried to install cm10.2 but that didnt work. I then did somethings and re-booted my device into stock LG G2. Then, a notification popped up telling me of a software update that was avaliable (MY LG G2 was already on 4.4.2 so i assumed this was for android 5.0 or something) I clicked update and now I am where I am now. My phone just goes through a loop showing the LG logo, then Showing the LG logo with "security error" under it, and then it goes to black and restarts that whole thing. The thing is though, when I go in to the Factory reset screen and press the power button twice to start the process, it goes back to twrp and when i navigate to reboot to system, the whole process just starts over again. Please if there is anyone knowledgeable on this subject, I REALLY need your help to be able to use my phone again. I am very new to the whole rooting process so this is something i dont know how to fix. Please help im begging you!!!
P.S: another thing to note is that, out of panic, i formated my phone's data from the wipe menu and thats how this all happened.

no need to panic...
1: from twrp format/wipe data system cache leaving internal (assuming you have stuff stored like pictures and etc)
2: sideload cm11 or any other rom for your model(assuming d800 here)
or
1: goto download mode and flash tot (reflash stock lg software). will loose everything on phone.
and do shutdown your phone properly to save battery till you download cm11 or tot.
via twrp choose shutdown and dont plug the phone
via power button looooooong press

What problem you're in?
well I am stuck in twrp, and can't use the terminal because of twrp 2.6.3.2 not responding to touch on the bottom half of the screen. My screen isn't broken. And I made the mistake by taking the OTA while rooted.
Hey guys,
Is data recovery possible after a flash? Also, what is wrong? I have searched but no answer directly hits on this. I am not a tech guy- Biology- sorry for that ahead. To the issue, I dlowded a software update to my Galaxy s3.....and boom froze on Samsung screen. I can turn phone off and on. It would not boot past Samsung. So I went into cache partrition, and tried a system reboot- cannot. So then I seen a program that supposively recovers data after factory reset if you do nothing else to the phone. However, problem I hit te dreaded factory reset- nothing. Over a software update? My computer is not recognizing the device. So I went to Samsung, they tried installing software, however, the computers were recognizing, but not connecting. One tech said they did not have flash- I went back again, the othertech said they did. Anywho, after 4 days, I forked my phone over to a repair guy. He I believe tried Odin- as it currently sits in odin mode. Now it was getting into download mode- but ow I have this message- " Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again." A samsung guy mentioned it might be able to be flashed, as my concern data- not backed up. This info is pretty important, as I have several contacts and mssgs. The two modes my phone can go into: Odin and recovery. I could really use the help, on both saving data, and getting the phone to fire- as it might be able to- but data?
Thanks in advance.

Before or after the a Flash? Thanks for the reply.
Hey XDA,
I have a D800 that is totally stock. I have no custom recovery, and have never rooted the device.
A couple days ago I got the notification for an OTA update. I hit the notification, and rebooted the phone. It started the update process. It got through the first step. When it started the second part of the update, a black box popped up, and a code like "ERR 0x04ff" or something like that popped up. The phone rebooted, and got stuck in a boot loop with a "Security Error." The phone will boot up, show the LG logo, then show a slightly different LG logo with "Security Error" underneath it, then reboot and start the process over. I started messing around with the power button and volume keys to see what different modes I could boot it into. Initially I could boot it to the Factory data reset screen, the Hardware Mode Keys screen, and I got it into Download mode once. I didn't have any of the software or files available at the time to do anything with Download mode, so I opted to try a Factory reset. The phone attempted a Factory Reset. The little android with wiggly ears, and the spinny cube thingy popped up for about 4 seconds, and the phone rebooted.
Since trying that initial Factory Reset, I have been unable to get the phone into Download mode. I've tried doing the Factory Reset multiple times to no avail. I have not seen fastboot at all.
At this point, the only thing I can do with the phone is boot it to the Factory Data Reset screen, and to the Hardware Keys Mode screen. It will not do a factory reset. The android pops up for about 1-2 seconds, and the phone reboots, and goes right back to the boot loop with the security error.
I'm at a loss at this point. I've called AT&T, and unfortunately my phone is out of warranty by about 3 weeks. So they can't just mail me a replacement. Does anyone have any ideas? I can't seem to get it to be recognized by my PC, on Windows or Ubuntu. I get the feeling that it's just hard bricked, and there really isn't anything else I can try.
Any suggestions would be greatly appreciated
TL-DR: Totally stock D800, no custom recovery or root. Security Error Boot Loop after OTA attempt. No download mode or fastboot, factory reset is ineffective. Not recognized by PC. What do I do now?

Thanks for the reply. I was about to reply saying my phone wouldn't go into download mode, but then I randomly decided to use a different usb port, and now it went into download mode.
I'll give it a shot now and see what i can do
Ok, It seems I'm back up and running. I followed this guide http://forum.xda-developers.com/showthread.php?t=2432476 which re-flashed me to 4.2.2. I'm going to try and upgrade using LG PC Suite from my laptop, and see if I have better luck this time.
Lesson learned, try every USB port when trying to boot into download mode.
Thanks for the help
So, I am fairly new to rooting and flashing roms, but I have done it successfully a few times. This past time, I flashed Cloudy Flex and everything was fine until my messaging was not working. After a quick google search I found a solution that said I needed to purge my internal memory cache and relfash the rom. I took this as wiping my internal memory and I went in to recovery to wipe everything before I flashed. When I got back into recovery, however, my rom was no longer there. I then made the mistake of rebooting my only to find that it can not get passed the LG logo. I also am unable to turn the phone off or enter recovery using the power and volume button. Any advice is helpful as I am stuck. When I attempt to enter either recovery or download mode, the screen remains black and the LED flashes red.

If you can't access recovery or download mode then your phone has become an expensive paper weight. You should take it to a service centre for a final verdict.
