[Q] Brick or no brick? - G2 Q&A, Help & Troubleshooting

Hi.
I have a Vodafone Germany LG G2 with stock KitKat.
My story:
I installed root and recovery. Then I tried to install the OTA, doesnt work, tried it with LG PC Suite. Boot certification verify error.
Recovered all with this guide:
[FIX] NO Recovery mode, No download mode, after OTA on rooted LG G2
http://forum.xda-developers.com/showthread.php?t=2582142
Then flashed an open LG G2 kdz and all was fine again, but...
no Update for me with knock code.
----------------->>>>
So i tried to flash the original Vodafone KDZ in Offline mode. I get an error at 15 percent and it wont work. So i restarted my phone, but i only had a black screen. Nothing worked again (no download, no recovery). Ok, plugged in in PC and woha, broadcom device detected. Back to ubuntu and recovery again (see above).
After that, i restarted my phone, but no recovery was there... only the lg logo. Everytime. Again: No Download, no recovery. Stuck at bootloop every time. Factory hard reset can be called, but if i confirm, "Factory reset processing" appears, now for ~30 minutes. Is there a way to fastboot or to another state than that?
Any idea?

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:​

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] LG G2(F320L) not booting after OTA with stock recovery with TWRP aboot

Hi,
First of all i committed a mistake of thinking that with TWRP aboot + stock Recovery i will be able to do OTA upgrade, which made my phone not booting, undetectable by computer and majorly not getting the LG Flash download mode by pressing any combination of keys., Stucks at LG logo.
Device: LG-G2(F320L)
KDZ stock: F320L21V_00.kdz
1. Flashed this kdz using LG Flash Tool 2014.
2. Flashed from F320L_AutoRec.apk, the images only aboot, and recovery.
3. From DorimanX project generated the boot.img with StockROM(F320L21V_00.kdz) version bootimage RAMDISK.
Everything was fine., till then.
After that, i got the OTA pop up., So, thought of installing OTA. As I had already faced the TWRP bootloop once and in some post i remember i read flashing OTA needs stock recovery image. Here is the place I commited the mistake. So, signed the stock recovery with aboot of TWRP using loki_flash. Accepted OTA. Thats it.
From then, no booting, no recovery, no adb, no fastboot, and unfortunately NO LG DOWNLOAD MODE also it goes.
When i try to go TWRP, it stucks up after the initial TWP message.
And pressing some key combination, the device goes to LG service mode, and showing the IMEI and some list of 3 options in korean which i dont understand. By pressing any of the option device reboots and stucks with LG logo.
Even my device is not shown up in the ubuntu, when i checked "dmesg".
Can anyone help to get the device into Either download mode or fixing the boot.
Sir,
Please wait until mods will move this thread to the device specific forum.
Stand by
Good luck
No solution yet?
The phone is still in the same state. Can anyone please suggest the solution to make the device working? Thanks in advance.

[Q] D800 Brick after OTA? Help, please...?

Just took the Lollipop OTA update from stock 4.4.2. Upon completion my phone rebooted and is stuck on the LG boot logo. I tried entering download mode (holding volume up button and plugging phone into computer) but my phone doesn't enter it. Attempting to power off the phone doesn't work either, since the phone just powers off for a second and turns back on to the boot logo. I tried factory reset (power + volume down) and after proceeding with the reset the phone is still stuck on boot logo. I've tried the Linux method here ( http://forum.xda-developers.com/showthread.php?p=48765620#post48765620 ) but when I enter the first command (ls /dev/sd*) I don't get a sdb where the device is detected.
What should I do?
same problem here, not with OTA update.
No Factory Reset available, no recovery mode, only download mode. Same as you with Ubuntu i find nothing...
Flashtool stop working after S/W at 9 %
Stuck on the LG logo ...
Help needed :/

Bricked LG G2 D802

Hi Guyz, so i managed to brick my phone yesterday. Was running Optimus G3 and decided to flash CloudyG2 3.3. Followed the instructions did a full wipe but when rebooted LG logo would flash for a split second then screen goes blank. The screen is on because can see the back-light but nothing boots. Tried a couple more restarts but the same thing happens. I did take a TWRP backup prior but when i enter recovery mode and restore the backup, when it reboots i get the LG logo then the android animation but then it freezes/stops on the Android text.
I then tried flashing stock rom via LG Flash Tool, downloaded both kitkat and lollipop kdz files, entered download mode on phone and got the firmware update message, went through the process of flashing with the flash tool but when it comes to the software upgrade part, it gets to 2% then fails. with a message - Upgrade stopped due to an error. I get this message when trying to flash both kitkat and lollipop kdz files and i have tried on both windows 10 machine and windows 7 laptop.
As i have access to recovery i have tried restoring backup many times but it just gets stuck at after the android animation, i guess my next step is to try the tot flash method but im struggling to find a clear guide on how to do this so any advice would be helpful.
Cheers, Justin.

Thanks, actually shortly after i posted question it fixed itself... i tried flashing lollipop again, the software upgrade started and it got to 2% then error. I left the LG flash tool open with the error on screen, disconnected phone and rebooted the phone... it went past LG logo and got stuck in boot just after showing android animation, so then i plugged in phone (wanted to see if could access phone via windows whilst stuck at boot) and after a couple of minutes the software upgrade window started on my pc so checked phone and it had switched into Firmware Update mode and was updating... so all good now!! Lollipop has installed and phone all working.
^^^ This may help someone with similar problem.
Thanks,
You should've flashed the kitkat bootloder before.. If you want to go back to cloudy ,flash the kitkat bootlader again..

Flashing Recovery Post Hard Brick

Hey,
I hard bricked my phone (no download mode, no recovery and no fastboot) and then managed to fix it (VIA SRK Tool) and got download mode back.
Now I need to install a recovery, and I cant go and manually check if the TWRP recovery is already installed or not, because if I do go to check and the recovery is not there then the phone will factory reset (and I'll lose all my data).
KDZ Method isn't working, it keeps saying I need to restart my device at 23% (same on two different PCs).
So is there any way of flashing the TWRP recovery through the download mode?
Thanks a lot
(I have a D801, I can get to download mode, factory reset screen and LG logo which then leads to the "Security error" coz there is no firmware in the phone.)
