So I somehow soft-bricked (I think) my d802 international LG G2 on CloudyG2 2.2. It displays the LG logo then 'Security Error', it loops when USB is entered. I have been able to enter Download Mode (however it keeps automatically initiating a Firmware Update staying at 0%).
I think what happened was, I was trying to flash the latest version of Xposed Frameworks, in order to do so I had to install TWRP, so I 'flashed' (presumably) TWRP using LGG2 AutoRec Lollipop, which I think made a backup before flashing, but when the phone switched off it is now somehow softbricked.
What would be the best steps to recover my phone? I was going to use 'LG Flashtoolnow' but I'm afraid that it will screw things up further because I'm on custom firmware. Is there anyway to retrieve data such as photos and videos if I have to flash to stock?
Any help would be great thanks.
Try using lg mobile support tool and perform an upgrade recovery.
I tried to perform an Upgrade Recovery, it tries upgrading the phone but after 2% says 'Upgrade stopped due to an error.' This is all while the screen is stuck at the 'Firmware Update' screen at 0%
Some updated information: Even if I want to flash to stock, is that easy after being on a custom firmware? Currently when I connect the phone during 'Download Mode' it automatically goes to 'Firmware Update' where it is stuck at 0% and says: USER B13 R00TED. I have a D802 international model I bought online (from Korea or Hong Kong, working fine in the UK) but I'm not sure what ROM to download, any help? http://forum.xda-developers.com/show....php?t=2432476

Ok, So I tried flashing Lightning Rom 2.0 using Philz Recovery. Installation went smoothly until the end where it failed to Lokify. I went ahead and installed the KK Baseband and attempted to boot. It was stuck in a bootloop. So I tried to boot back into recovery but being that I'm using the D801 model I had to flash Smiley's rom to remove recovery in order to avoid the "white lines" bug. So now I'm stuck with a rom that won't boot and no recovery. And when i try using LG Flash tool it says "Download Fail" " Device model is different". I know I'm using the correct files as I've used LG flash tool like 7-8 times on this phone. I think the rom failing to lokify changed the device model or something because even the bootloader looks different. (Before the interface was smooth, now the "No (exit) and Yes options are in boxes and turn grey when I highlight them. Someone please help me.
Hey everyone I'm quite new to android, and I'm currently stuck in Download Mode after trying and failing to install Twrp
I was previously Rooted, tried to install Twrp via Autorec, however when I ran the app it soft-bricked my phone and put me into Fastboot mode.
I followed http://forum.xda-developers.com/show....php?t=2476972 method, and got back to Download Mode.
I am currently in the middle of returning to stock through http://forum.xda-developers.com/show....php?t=2432476 using the .TOT method.
I'm fairly close to repairing it but my only issue is that I cannot get my computer to recognize my phone. Neither in Device management nor adb devices anymore.
Therefore I cannot change the port to COM 41 to flash the .TOT file.
I constantly tried installing drivers for the phone both 3.10 and 3.08 but still no recognition can anybody help?
Some more info about the phone:
it's the D801 variant but its on Wind (Canada) not T-mobile
it was previously Rooted
it did not have any recovery software installed
no roms had been flashed previously.

Try to restore your phone using the official LGMobile Support Tool. Just switch on normally the phone, plug it to your PC and wait for your kdz to be downloaded. Once it done, it should install the kdz by itself. Then factory reset your phone (if needed) as it should ask you some pin/password.
Hope it'll help you as it did for me!
I've got a T-Mobile D801 and tried flashing to the stock lollipop rom D80130b_00 using TWRP and the instructions on this page, but the flash must have failed. I did a full factory reset back to stock 4.4.3 prior to attempting this flash and I'm not sure what (if anything) I did wrong for the flash to fail. I can boot in factory reset mode and select clear everything, but then I just see the android guy with gears turning for 2 seconds and the phone reboots again.
Now I'm in a bootloop where I get an "error: Boot certification verify" above the T-Mobile startup logo followed by a "Demigod Crash Handler: Critical Error!" screen that provides options for rebooting (volume down) or putting the phone into download mode (volume up). After using the volume up the screen displays "Volume Up is pressed: Jump to Dload mode" and after connecting via USB appears in device manager as "LGE AndroidNet USB Serial Port (COM41)". I can't (1) boot directly into download mode or (2) get back into TWRP.
I've tried both the KDZ and TOT methods listed in this thread and neither are working. The LG Flash Tool 2014 / KDZ option starts the LG Mobile Support Tool, but it fails every time once "S/W Upgrade is in progress" reaches 4% with a generic "Upgrade stopped due to an error" message.
The TOT method fails every time with a "Model Information Check FAIL!" message. The full text is - "PID: NULL, IMEI: NULL, Model: , DLL:801, BIN: BIN_LGD801AT-01-V10c-310-260-AUG-13-2013+0.tot , SWV: , SWOV: , Model Information Check FAIL! , 00000000"
I've also tried using srktool to repair fastboot, but it gets stuck at "waiting for device".
What do I try next?
Finally got back into 4.2.2 using tot method. LG Mobile Support Tool doesn't think updates are available though??

Yes, I *think* what happened was that my 30b bootstack was flashed successfully via twrp, but then the actual kdz flash of D80130b_00 failed. I had a lot of trouble at this point - needed to fix qhsusb_bulk problems first, then use the more aggressive TOT flash method to reset to stock 4.2.2.
Finally the LG Mobile Tool was still reading it as having D80130b_00 / lollipop after going back to 4.2.2 via TOT (?). Last step was to do a full restore from the LG Mobile Support Tool (options -> upgrade recovery) and it actually downloaded / flashed D80130b_00 so everything is working well now :good:
If it helps anyone I used the LG backup tool to restore apps / media and have to say that for a stock solution it's pretty solid.
qhsusb_bulk?

you said your g2 was detected as a lge androidnet in device manager but not as a qhsusb_bulk...then what problems have you fixed about qhususb_bulk? and what is the more aggressive tot method different from this threadhttp://forum.xda-developers.com/showthread.php?t=2432476
Were you able to find a solution? I'm in the same situation. Please help!
Update,
I fixed this problem by using LGUP. My phone was refurbished (ls980) so that's why twrp didn't booted,
Hello,
I have a LG G2 d802 32gb variant. I bought it a week ago. I was running andoid kitkat OS (HK D80220C). It wasn't rooted. I tried to get official updates from about phone section but "no updates". So i decided to manually flash updates from a rooted recovery as i did in my LG G3.
First of all I rooted it by "IOroot". Then tried to install custom recovery by "autorec d802". Everything went good and autorec was also successful. I asked me to reboot into recovery, I pressed yes and then it took me to "fastboot mode". I tried to reboot into OS by pressing power button (As battery is non-removable). Everytime it rebooted back into that fastboot mode. This once happened with me on LG G3. So i tried to flash "laf" and "recovery" image and downloaded from here
http://downloads.codefi.re/autoprime/LG/LG_G2/D802/Stock_Firmware
I flashed them by CMD fastboot method. Now it stuck at "LG Logo" and download mode was also started. So i decided to install a stock rom by KDZ or Tot method. First i tried KDZ method. I downloaded stock rom "Hong Kong D80220C_00.kdz" which it was previously running. Also installed all drivers, downloaded flashtools2014 and connected phone while in download mode.
I started KDZ method as told here
http://forum.xda-developers.com/showthread.php?t=2432476
But everytime it shows internal error on "2 or 3 percent". It didn't worked for me. So i decided to do tot mothod.
Download tot file, dll file, LGFlashtool, drivers etc.
Followed whole process which was also described in above post. But when flashtool reached at 94 percent and mobile was being rebooted it showed error
"Fboot check"
"Fboot Check"
"Can't reboot completely"
I tried to turn of phone at this condition by waiting and then doing a factory reset by keys combination but it keeps resetting and rebooting. I searched whole internet but can't find a solution. Can anyone please help me. Because i bought this cellphone a week ago for my friend and i would not be able to face him after showing a sick phone. Please someone help .
Only download mode of phone is working, It also keeps led light on while stuck at logo.

Hi so my friend gave me his LG Leon to flash CM 12 because he didn't use it anymore. For my surprise when i turned on the phone it boots automatically in flash mode showing "910K" in the little box. I try to flash a kdz but nothing works, when the phones restarts boots in flash mode again.
I installed TWRP but always is showing that is not detecting the OS.
Why can I do?
Is a corruption of the partitions?
help
Try to flash a official rom using LGMobile Support tool. Connect the phone, open the program and Select "Option -> Upgrade recovery".
From what I can gather, the recovery was either replaced with an incorrect version or was corrupted.
