Hi guys, skipping the introductions, I somehow unrooted my F320S (I have no idea how!) and am currently unable to use even the download mode to get back to stock ROM.
Technical details:
F320S, Korean LG G2.
Was rooted since October
Lao Hong rom (before the upgrade)
The story behind it:
1) I upgraded my phone to 4.4 on "Rom VDT-V9 Cho LG G2 4.4 Kitkat" and found myself unable to access the recovery menu. I thought it was an outdated TWRP (2.6.3.2) causing the inability to access the recovery and decided to flash CWM (6.0.4.4), but was still unable to access the recovery. Even though I had flashed CWM, it did not cause any problems as I used the phone as normal during the week up until today.
2) Wanting to remove the navigation bar, I messed with the build.prop file and caused the system to "brick", and being unable to access recovery, I went to download mode (yes this isn't the first time I bricked the G2) and went through the mobile support tool hoping to revert to stock.
3) However, I got stuck in a bootloop on the boot animation screen and read on a reply to the thread (http://forum.xda-developers.com/showpost.php?p=49822996&postcount=1794&nocache=1&z=448867873440083) to do a hard reset on the device (Press vol down and power, then press power when the LG logo shows) but the confirmation failed to appear.
4) Now, I'm stuck in an endless bootloop, unable to access recovery (as I suddenly became unrooted) or do a hard reset (hard keys do not work) and unable to use the download mode to revert to stock (endless boot loop after the upgrade completes).
edit: It seems like when I'm doing the upgrade in download mode, the phone finishes the upgrade before the mobile support tool. I don't remember this happening last time I did it...

Try this...Hold the vol down and power and have it reboot at which point hold just the power button till it turns off. At that point try the volume down power till LG logo and then just power and see if that lets you access the recovery. I fought many times with the buttons to try and get into recovery and the easiest way was always with the phone off to start with.

I've been trying to get into hard reset this way for the past hour or so, but I think it might be a different key combination for the Korean models? Accessing recovery mode was vol up+power for mine too. I tried with both vol up and vol down, holding vol down all the way and releasing it after the lg logo boots, but i still have yet to find the right combination.
Thankfully I'm not fully crippled as I have my trusty S3, but I'd like to get the G2 up and running.
Just wondering if the fact that it was unsyncronized while in download mode affected anything? My G2 shut off before the download mode was at 100% complete, and I don't recall that happening the last time I used download mode to unbrick my phone.

So I don't know why this happened, I had rooted and installed TWRP and was happy, so I tried to install Malladus (1.2.9) and gapps and the 24a upgrade .zip, and now here I am.
I've tried most methods, and the LG Flash tool just says "failed PreviousLoad()" when I click the yellow arrow.
I f'd this phone up 12 hours after I got it.
If you see the LG boot logo than there is still a chance to fix the phone. Try to manually go back into recovery. Turn off the phone by long pressing power button. As soon as the screen is black, press power and volume down together, you only get a half second to do it. When LG logo appears release and press them together again until the factory reset screen comes up. Then press power 2 or 3 times and you should go back into your recovery. Once there you can try to reinstall rom, backup or side load a new rom. Hope this helps!
What is your phone model? Without that I cannot help you.
Same problem
Hi guys, like an idiot I was successfully able to install the debloat 4.4.2 on my vzw LG G2 but I tried to flash nandroid recovery back to my 4.2 and now I am stuck on boot loop and cannot get back into recovery. I tried to hard button by pressing both the bottom button and power, and press it again when the lg logo comes on and after pressing the power button a few times, it just goes into a black screen, so I cannot get back into recovery in this manner. Anyone know how I can get back into recovery without going through the full wipe back to factory?
I know that there are loads of threads on XDA regarding bricked G2s (and how to fix them), and believe me, I have scoured every one I could find. None of them had the same situation as me. Here it is:
- tried upgrading rooted G2 (d802) to KitKat through PC suite
- on reboot, phone gives repeated "Unfortunately, com.android.systemui has stopped" messages
- this prevents me from doing anything - cannot start developer tools/USB debugging; cannot software factory reset; may as well have a broken screen
- tried booting into recovery - there seems to be no recovery
- I have booted into recovery before the update; I tried using the same method - nothing
- I googled for alternate methods, none of them worked either
- has download mode - what does this enable me to do?
- tried using a 'restore to stock' flashing tutorial on XDA - didn't work
- it is here if anyone was curious
- cannot access through ADB
- TWRP gone
- have no idea how to access through fastboot
Any other options available? Is there any other way to enable USB debugging, trigger fastboot, access the phone through ADB, or factory reset it?

ok well first entering factory reset(or custom recovery)
-before d80220d the key combination to enter factory reset is with phone fully powered off hold volume down+power and when lg logo pops up let go and hold volume down+power
-after d80220d(or any update that includes knock code) the combination was changed(pretty sure it had to do with the fact that on kitkat we used stock recovery to install root and everyone who couldn't get in via adb just had to use button combination which everyone knew) and the new combination with phone fully powered off is to hold volume down+power and when lg logo pops up let go and hold onto volume up+down don't touch power, if you have tried these then you should mention it

You are an absolutely beautiful person. I think I have fallen in love with you. THANK YOU SOOOO MUCH! I swear I found at least 5 different tutorials and none mentioned this.
If your name doesn't go down in history, the world is cruel and unjust.
Sorry. But thanks. SO MUCH.
Im facing the same problem, wanted to go back stock and had CloudFlexy 2.3 installed. Did the firmware flashing, got stuck with procesesses stopping and couldn't boot into factory reset.
Found this thread and got to factory reset, tried factory reset but now my phone only has android figure with spinning thingy inside of it going on in my screen. ADB wont recognize the phone.. I think i need to flash stock rom or something but not sure how to. Please help, how did you proceed rtswan1211 after getting the factory reset screen?
Edit:
After waiting for 'bout 10mins for something to happen i just tried to reboot the phone and still the same spinning android logo came on. Finally plugged in the USB cable and phone booted up with working software. Had me really worried.

after tried several times, FACTORY RESET successfully done.
Previously, I updated the 20G through custom recovery and forgot to wipe clean. After completely installed the 20G, error shows blocking the screen and the custom recovery was gone. after several attempted, I succesfully done by:
- turn off the phone completely
- press vol down and power
- release immediately, upon LG logo pop up, and
- press vol up and vol down
- Factory reset menu pop up
Seems now is harder than before, I need couple times to try before succeed

I have the same problem, no download mode on my G2 (European version, stock kitkat without root, bought it a week ago).
Just to be safe, the way I tried to launch it into download mode was:
1. Powering off the device.
2. Holding the volume up button.
3. Plugging in the USB cable (while still holding the volume up button)
The LG logo shows up for a while, after which the charging animation shows ups...

Your phone must be turned off
So, press power button and select “power off”.
Then, press the volume up button on your LG G2.
While you are holding the volume up button, plug in your phone’s USB cable.
Keep pressing the Volume up button until the download mode is being displayed.
that is the known method for G2 unless you flashed a custom boot-loader or changed the keys to enter download mode or recovery etc .... now try to enter a hard reset mode but don't apply it or all your data will be gone i say again don't approve it it is power+Vol down
if it works i think the keys combination are still in default then try to enter download mode again
if it didn't work return the mobile to be fixed or changed
Thanks for your reply!
The method you described is the same as the one I used, unfortunately it doesn't seem to work. I can't seem to get it to boot into recovery either...
I believe this reddit post describes my problem:
https://www.reddit.com/r/lgg2/comments/2n4gqa/unrooted_lg_g2_on_stock_android_442_kitkat_will/
The OP's conclusion is:
So I rooted and installed AutoRec and that got me Download Mode. Afterwards I used LG Flash Tool to flash the stock KDZ file onto my device to unroot it and to see if Download Mode is still enabled which it was not.
I believe this is LG's way of preventing users from upgrading to unofficial/unreleased firmware.

I managed to fix the issue by performing an emergency recovery using LG software. It must have been caused by one of the OTA updates.
Hello,
Yesterday I tried to upgrade my LG G2 from android 4.4.2 to 5 via LG PC suite.
The upgrade was failed at some point around 30%, it let me re-try the upgrade, but it fails over and over.
After deep research, I found that it could fail due to lack of space (Under 1GB), unfortunately I think that's the root cause of the failure. (No alert was given before the upgrade)
Now, it stuck on the Firmware Update screen (even after reboot), attempting to get into download mode direct me to the Firmware update screen.
The only thing I was able to perform is getting into the Hard wipe screen (holding vol down + power button till device is powering off and powering on, when it power on with the LG logo I let go the vol down button and keep holding the power button), I chose to reset factory, but I think it just restart my phone into the Firmware Update screen and perform nothing.
This is un-rooted device, made in Korea. Sorry, but I don't know the current firmware version.
Any help please, if anyone know how can I delete data without the OS it could help.

Hey guys,
I feel totally stupid for writing this post but I'm actually out of ideas how to get out of my situation. Also I didn't find any comparable topic here on xda. So let's hope you can help me and a big thanks in advance!
First of all i have a flashed D802 running TWRP and CM13, which worked well the last weeks. I thought about updating to the todays nightly as it is already a few weaks since I did my last update. I downloaded the nightly via the CM downloader and started the installation with running phone. It rebooted into recovery mode and installed the nightly without any problems. After the installation was completed the phone automatically rebooted and this is where the problem starts.
I am stuck in "bootloop?" at the CM logo. It is not automatically restarting after a while but just loading and loading and nothing further happens. I am not able to enter the recovery mode via the factory reset (Pressing Vol Down + Power, releasing after the lg logo appears, pressing and holding the power button again).
This never happened to me and as I am not able to enter TWRP I am not able to install a previous release or a backup. What am I doing wrong this time and what can I do?
Thanks for your support!
have you tried flashing a stock rom?

Actually I don't really know how to do this when I'm not able to enter the recovery mode? Is there a certain way to do this?
In the meantime I managed to enter the recovery mode / TWRP via a mode I don't know how it is called. I pressed vol down + pw btn, released after the LG logo appeared and pressed vol up + vol down. I guess my userdata is deleted by now, which shouldn't be a big deal but I am getting redirected to the recovery mode. I tried to install the yet working CM13 nightly but it has the same problems now.
Now I have two questions:
Does anyone know which part of the system is broken now / which part I need to update in order to get my phone back to life?
Is the download mode working if my phone is rooted? I am able to enter this mode.

yes you can enter the download mode: turn down your phone, press and hold volume up button and connect the usb cable, release volume up when your screan shows dowload mode.
