Bootloop problem, no recovery, no download mode (Non rooted and No custom recovery)

Hi, I just bought an LG G2 D802 20B Model a couple days ago, yesterday I wanted to downgrade to 4.2.2 and I ended up bricking the phone.
The phone is non rooted, doesn't have any custom recovery, and not recognized by adb even though i installed all the drivers ( koush drivers, PdaNet, Lg drivers ...)
At first I flashed with .kdz file and it ended in bootloop, I tried to factory reset but it doesnt have any effects with the stock recovery it only shows the green android bot and blue progress bar and then restart in 3 seconds and reboots to lg logo and start looping.. After a restart the download mode didn't work anymore it showed me fastboot error, I searched for the tutorial that actually worked and I flashed with .tot method but there is still bootloop and the download mode is stuck at the image attached. The phone is not recognized by neither windows or ubuntu therefore I can't use adb to fix the partitions.
Can any body provide me with a solution? The phone is still new and it will be a shame if its transformed to a brick in 3 days :crying:​

Hey..hmm i think thats how download mode it is...so did you tried to flash again a firmware?

Thanks for your reply, however the phone is not recognized on windows neither on ubuntu therefore this tutorial can't help ...

I am in the exact same situation.
Mine is a D802 32GB Hong Kong model. I stupidly ran AutoRec which soft-bricked my phone. Managed to get Download Mode working, then flashed 20C and 20B which bootlooped. Then I attempted to flash 10B, which got me into this exact state:
Download Mode not working (only shows "Download Mode", does not go to firmware recovery screen, not detected in Win/Linux)
Factory reset (Power + Vol Down) can go to factory reset screen, after factory reset, still bootloop.
Once in a while, I also get the Android icon which then disappears after a few seconds and goes to LG logo again.
If I plug the phone in and do a factory reset, Windows detects the LGE AndroidNet modem, and Linux will detect cdc_acm USB Abstract Control Model driver. Flash Tool and LG Mobile Support seems to detect the phone and attempt to flash, but the phone restarts after a short while.
I have no idea what else to do

[Q] Ruined Fastboot mode, but regular boot works?

Okay, so not sure what I did here.
I have an LG G2 ATT version with 4.2.2 installed.
I was trying to install CM, which I already have on my Nexus 7 and love. But the LG G2 doesn't have a nice one-click install app like the Nexus 7 does.
So, I managed to root it, and got SuperUser installed and Clockworkrecoverymod.
At one point I also had TWRP installed, and I think that is where I went wrong. I went to flash a new fastboot / recovery mode and think I selected the wrong one (LG G2 International).
Ever since then, attempting to reboot into recovery using the hardware method (volume down + power) doesn't work. If i force it into fastboot mode using Clockworkrecoverymod or ioroot, I get a strange message.
All the phone shows is white text on a black background:
[830] Fastboot mode started
[940] -- rest --
[950] fastboot; processing commands
then, if i unplug the USB port, I get a few messages. If I replug it in, I get the above message again, with different time stamps.
If I boot normally, it pulls up the normal stock OS, but any attempt to boot into fast mode gets me this message. I can also boot into download mode, but it hangs at 0 %. I tried Flashing a new Recovery using clockworkmod, and it says it worked, but booting into recovery just results in ending up in the same Fastboot mode deadend.
I see the same message if I try to factory reset the phone through the normal software method in options.
So, it is great that I didn't completely brick my phone when I idiotically installed for the wrong mode, but without being able to get into fastboot mode, what are my options for getting back on there and back to stock so I can try again?
And yes, I tried to make a backup on my device, but when I went to go back to it, clockworkmod said it isn't there. Not sure how I messed that up, but anyone have any suggestions on what I can do going forward?

As I understand; If you're trying to boot it to recovery mode, it goes to fastboot mode, right?
If I understood right; you need just flash recovery to your device.
G2 has a different boot process from other devices. If bootloader failed to boot the thing you want to boot, it goes to fastboot mode. That's why it goes fastboot mode when you try to boot it to recovery.

Ah yeah, i just couldn't figure out how to get it out of Fastmode. I was a little confused about the difference between fastmode and recovery.
I seemed to have fixed the problem by AutoRec, for whatever that is worth. Now it boots into TWRP's recovery mode. Shouldn't be hard to get cyanogenmod now.

What Options Have I Got At This Stage With A Bricked D802

I installed autorec recovery.as soon as i booted I realized the presence of white lines which have never gone.I cant flash any zip file such as the JDI kernal.It cannot enter into download mode even after erasing recovery, laf, aboot, boot and flashing back stock aboot, boot and laf.I cannot see the LGE port so I cannot tot it back neither does kdz flashing work since it cannot go into download mode.Adb doesn't show up.
What I got is only fastboot + white lines (they only cleared up once by luck so I could see fastboot mode on the phone) .
Please help me Un-Brick it ASAP.look at the questions below.
Thanks
-Should I re-flash all 12 partitions via fastboot (use twrp as recovery).
-It is written d802 on the cover but could the motherboard be different inside?
-Supposing I was to flash 16 GB to a 32 GB phone or vise versa would it affect anything.
-What are my options at this stage and what is the best method to approach this

http://forum.xda-developers.com/lg-g2/general/mega-tut-how-to-fix-bricked-lg-g2-t3055033
Would This Guide Work? I have seen in other guides where they warn about replacing the original recovery but rather suggest you use twrp.
-I think this is a refurbished device.

UPDATE
ok So I managed to fix the white lines and they have completely disappeared which is a plus point.I can finally see download mode for a second before it disappears.I can also go to factory reset mode after holding vol down and power but I have not reset it yet.
Any fix for 1 second download mode?Once I get to download mode i can tot back.

if you have custom recovery try different kernels, wipe, flash bootloader you must be on download mode to revert to stock.
at this point if you cant use the download mode at all, you must try riffbox(search on google)

Holy Mother Of.......The RIFFBOX is crazy....i do XBOX 360 modding and i know the difficulty..hehe.....Actually I see download mode for a second and it disappears........which custom recovery can i flash via fastboot, philz or twrp and which ones are the right ones to download.....i am already pissed off at autorec.i feel I am getting close after I cleared up white lines now only fastboot stands in the way.I know many people who mess up and enter bulk mode at this stage and I wanna avoid.I also cant find the right kdz file for my LG cause the imei is a spoofed one that is invalid in the first place so i am hoping for a miracle at this stage.Thanks for the help.......what do you think I can do apart from riffbox?

Just try everything you see on xda. I never faced a 1 sec download mode before and believe me i bricked(hard/soft and beyond) many times and came back, it aint die. Once download mode is broke there must something really not working. In other saying you need to revert to stock. Also, if you dont have custom recovery i also dont believe you can flash a custom recovery, you could try adb push laf.img recovery.img aboot.img etc. But its going be hard bricked.
Man i was thinking i faced every difficulty with d802 but you proved me wrong :laugh:

I pushed the three files that's when the white lines cleared up and download mode came for a second....there is a similar case on Android forums where they download mode comes for a second. The worst part is the IMEI was patched to a very u usual IMEI on the back cover, it's not even an LG imei so i can't find the write kdz file to extract partitions from....I have to rely on trial and error......at this stage I don't wanna enter qhsusb mode aka hard brick...... I just have to revive download mode.......actually when I attempt to boot laf. IMG I get a dtb error ?any thing I can try

So I just wanna confirm this. if i flash any custom recovery say cwm (of course for lg g2 d802) via fastboot mode using the command fastboot flash recovery recovery.img will it actually install the recovery or what.and then to enter recovery i have to essentially hard reset (vol down + power ) so as to enter recovery.now if there is no recovery it will hard reset and i will enter qhsusb mode which i dont want.So does flashing a recovery image via fastboot install the recovery or what.Please assist.

LG G2 Hard Bricked

So I wiped the system partition on my LG G2/D800 (mostly out of stupidity) and now I'm stuck in the boot loop.
Symptoms are following:
1. Stuck in the boot loop
2. Will not go into download or recovery mode
3. When turning on the LG logo appears and disappears repeatedly
4. Device is not detected when plugged into the USB
5. Factory reset using VolDown+Power doesn't do anything
I've tried most of the ideas I've been able to find on the forum, but it looks like I'm stuck mostly because I cannot enter download mode and the phone is not detected in any way when plugged into the USB (no many partitions or anything).
Will be grateful for any ideas how to get out of it?

so vol up and then plug usb, does not take you to download mode?
if not try using srk tools.. if that doesnt work i think you need to short circuit your motherboard.

Indeed I cannot enter download mode with vol up then plug usb.
Good news is that I was able to enter qhsusb mode by short circuiting the moterboard. I used srktools to unbrick in qhsusb mode, however it didn't work. The linked guide recommends to flash only laf.img, aboot.img and boot.img. I don't really understand how flashing more can hurt. I also don't completely understand why flashing these should help. After all, I messed only with the system partition. I'll try to follow the guide more closely, but I'm thinking that a better idea would be to flash system partition in a qhsusb mode. I just need to figure out where to get system.img from.

So now I can consistently get into ghsusb mode by short curcuiting the motherboard, and I can flash img files with dd. I flashed every partition from the stock FW which was on my phone. Now when hold vol up and plug in usb, I'm ending up in a stock recovery. However, I still cannot enter download mode and the phone still suffers from boot loop if I choose to reboot the phone.

Bricked LG G6 H870

Hello all,
After having trouble to boot to TWRP through recovery (and when the phone was still functional), I messed around and flashed TWRP through Flashify and now I can't even go to the OS. When i try to get to recovery I get sort of a bootloop in TWRP and I also get this if I simply reboot the phone. At this point I already lost all hope since I think the phone is bricked for good.
If someone have any idea how to get through this I would be very pleased.
Thanks.

Have you tried to flash through lgup?

I had the same problem last week and i said the same (bricked phone)
this solution worked for me after 100 attempt
before the LG logo appear try to enter to recovery (volume down + power button / release power when the logo appear and click again )

try this, from the unlocking guide
https://forum.xda-developers.com/lg-g6/how-to/official-lg-g6-bootloader-unlock-t3614719
Alternatively, you may be able to boot into fastboot without ADB by powering off the phone then power the phone on while holding Volume UP (USB cable will need to be removed otherwise it may boot into LG Download Mode)

if it boots into fastboot you should be able to flash twrp.img from adb
then i would go to recovery and start fresh by wiping everything :victory:

Hi guys,
Thanks for the support! It turned out to be a corrupt SD card I had in the phone that was causing TWRP to get screwed.
Thankfully everything is working fine .
Neverheless, thank you all for your support.
Thread can be closed, issue solved.

happy for you bro
