[Q] Need help to fix my bricked LG G3 - G3 Q&A, Help & Troubleshooting

hello geeks,
I really need serious help. First the setup I have is as follows
1. I have LG G3 D855 but its european or Hong Kong or Taiwan version I don't know. I bought it in India. I updated it to android 5.0 Lollipop. Everything is fine till now.
2. Then I rooted my phone. This step was also fine. No problem.
3. Then I tried to download camera mod v2.0 to get some extra camera features like 60fps. In this step I got problems. I downloaded the media_profile.xml and copied it to /system/etc. But I made a mistake that I did not change its permission and rebooted the phone.
I am troubleshooting from a windows 8.1 PC. I downloaded the LG USB driver.
Due to this my phone stop at initial LG,Life is Good Screen. I tried different methods in internet.
1. I tired to access the device file file through adb. But the adb does not list the device.
2. I tried to use fastboot mode, but still fastboot does not list device when in the boot screen.
3. I pressed down pwr + volume down button and release after screen come up and then press again. I was asked to erase user data. I said yes and it erased the data. But still the same symptom when I reboot. Stuck at initial screen.
4. I tried to use LG PC Suite. But it does not even detect phone through the USB and there is no repair button.
5. I tried to enter downloading mode. This one is strange. I pressed down the vol up and then connected USB. But sometimes only it enters downloading mode and sometimes not. May be once in 10 times it enters downloading mode and 9 times it goes to initial boot LG screen.
I am not sure whats going on. Can anybody help me to figure it out ? Please help.

Thats because your not doing it properly
Research a guide on how to enter download mode and after that you can use flashtool to wipe your system and reinstall the original lg firmware

[Q] Rom install failed now can't boot

Hi guys, so my problem is I was installing a new rom on my rooted D855. everything was going along fine but then the process stalled. I left it running for 15 - 20 minutes but it was still on 33%. I tried holding the power button in desperation which shut the thing down. Now when I try to factory reset it goes to the prompt screen, I answer yes, then it asks me to confirm. from there however it goes to LG splash screen and eventually a black screen with Fastboot mode started. -reset- portcharge -reset- portcharge fastboot: processing commands in the top left corner. That's it.. If I try download mode it goes to the download screen and then to the black screen as described above.
Sounds pretty ordinary but if there is an answer out there I am sure one of you guys will know it.
TIA
i had some similar other issue and the only way i got out of it, is by using the lg flashtool 2014 and the KDZ file appropriate to your version
there is a thread with a step by step instructions.
you launch the flashtool, then insert the kdz file (original stock rom) then you put your phone into download mode (making sure in windows/controlpanel/devicemanager/ports - comp port 41 for the device driver)
you press volume up and plug it into the pc, the pc sees the phone and it starts reflashing the custom rom to your cell.
i presume that as soon as your download mode is working by flashing whatever command is corrupt and makes your phone black should be bypassed by then
i hope it helps - look for the thread how to flash the lg
Thanks I'll give it a shot. Not sure device manager is seeing it properly. I'll have a play and see. Thanks again for the reply
O.K here's the thing, my phone is seen in device manager as a Samsung Android Phone. Under the details tab it shows it connected via USB Modem Phone ADB Port. There is no option to change the port to 41. Anybody who can help I would be very grateful......

Stuck in Fastboot boot loop after OTA update -- HELP!

So I just got an LG G pad 10.1 VK700 from Verizon the other day. I rooted the device on the first day but never really added any additional apps or software.
Another member in the household was using the tablet and it asked if they wanted to accept the VZW Update for KitKat 5.0. They downloaded the update, and now the tablet is stuck in a bootloop at the Fastboot screen.
There are only 3 options I can select from this screen in the top left using the volume keys: RESTART, RESTART BOOTLOADER & POWER OFF. Any time I select either of the restart options, the screen just goes blank and hangs. I have to manually power off, and upon turning back on I am right back to this limited Fastboot menu.
Bottom left reads:
FASTBOOT MODE
PRODUCT_NAME - E9LTE_VZW
VARIANT - e9lte_vzw Toshiba 16GB
HW VERSION - rev_10
BOOTLOADER VERSION - N/A
BASEBAND VERSION - N/A
CARRIER INFO - N/A
SERIAL NUMBER - VZ7005xxxxxxx
SECURE BOOT - disabled
LOCK STATE - locked
I booted into Recovery mode, but any of the options I select from the System recovery menu send me right back to the Fastboot screen.
Is there anything to be done at this point?
UPDATE: Problem solved. Research into the other variants of the LG G Pad lead me to the the LG Mobile Support Tool, which you can find by googling B2CAppSetup.exe.
Now, if you are stuck in a Fastboot loop as I was, I ended up having to restart the device while holding down the Power + Volume UP & DOWN. This brought up a screen displaying a bar code and the device MSN and IMEI number. Using this number return to the LG Mobile Support tool and select Options>Upgrade Recovery. Even if your device is already plugged in via USB, the software will not recognize the device -- you may want to double check to make sure your device drivers were installed prior to this step. Input your IMEI number into the box and restart the device in to download mode. It took a few attempts due to the quick action of Fastboot, but I was finally able to access the menu while USB was plugged in to the device and restarting while holding the Volume + key. Now you can continue with the installation and you will be back into your tablet in no time.
I have access to the device via usb / fastboot, adb is not registering. If anyone has any suggestions on what I can try, please let me know. I do not have a backup or a version of the OEM ROM. Every effort so far just sends me right back to the Fastboot screen with 3 options. Anything I can run from command prompt using fastboot alone that would help in this situation? Any way to do a factory restore without having an actual OEM image?
Well im stuck at the verizon screen too but for a different reason

Hello I have the exact same model I got 28th my g4 and successfully rooted with kingroot and used supersume to change it to supersu. Everything was perfect and running fine and I tried an entropy engine I use on my other rooted phone and it was not help so I disabled it and rebooted like I have with my other one before and it stuck at that horrible red screen lol. I haven't done anything else major to alter anything to do with the OS like installing an OTA and I can only get to the same screens as you. My problem is I don't have a PC and haven't in a very long time and if I get to one I wouldn't know where to start out, last computer I owned has a floppy disk lol but I don't see how I would need to re flash the entire OS because of an entropy engine hickup. If you or anyone know of a way to slap this thing back to reality I would highly appreciate it. I got very familiar with the android os and how it works but never had a PC to go beyond a basic root so technically I'm still a noob in a way. I only care to expand dual window to other apps if I get it fixed cuz I'm not gonna risk screwing with it any more now than I have to, my luck is too bad lol thanks in advance

If you are stuck in this particular Fastboot loop without a computer I am afraid your options are going to be very limited. The only thing I can imagine that you would be able to try is restarting the tablet while holding down the Power + Volume Down keys to access the stock System recovery menu. You can try to use Factory data reset and Wipe cache to see if that can resolve the issue, but for me every attempt to perform actions from this menu brought me right back to the Fastboot screen. The only other way I could communicate to the device in this scenario was using command line, and even then I could only access fastboot and not abd.
I would highly advise getting at least a cheap older laptop with Windows if you plan on rooting any device, otherwise the dangers will far outweigh the benefits. I'm just hoping some development comes along for the VK700 G Pad 10.1, at least a TWRP or CWM release.

Thanks for your response, I have unfortunately tried that too and wipe cache, reset , all back to fastboot. I figured it would be impossible without a pc. Oh yea my stock recovery says modified in the top left corner, but anyway I can get access to a PC But honestly it's been awhile since I even needed to use one and don't know exactly where to start, like navigating around, and how to install what software on the pc. I can't find anyone that will walk me through it locally or online and every tutorial I find is missing some lil step I need. I know Android in detail but after basic root my experience hits a brick wall. I'm capable of more jus got to get broke in on a pc again. Now I only care to root for stuff like freezing apps, gesture control, and really want to use any app in dual window. Ain't screwing with any system tweaks again it was pointless lol I guess I need all the right files and hit up the pc...can't really do worse no??

Oh yea I almost forgot I got side tracked earlier. I know there is already a twrp, I have 2 versions (2.8...something and the next version strait off twrp site. I was the one guy it wouldn't flash through flashify for but others claimed it did. God knows really, but I'm gonna wait till I have a PC of my own before I touch my g4 but man the ability to open any app in dual window is just too damn sweet...if I could only change that one word on build prop to false without all the other hassle

I tried following your recommendation, but the LGMobile Support Tool said the device wasn't plugged in no matter which combination of buttons I pushed while running the Upgrade Recovery option, and I wasn't able to figure out how to get to download mode either.

If your problem is from an OTA failing due to taking it while modded and you can get to fastboot the following command might fix it:
Code:
fastboot erase cache
That will delete the OTA zip and break the bootloop.

Solution for Hard Bricked LG G4 (9008)

Hi guys,
Some people including me faced Hard brick issue with LG G4, which has now two solutions. the first is temporary, i discovered it and it involves using an SD card flashed with Original EMMC dump ( i tested it with H815 ands H811) , the second needs advanced hardware, equipment and soldering skills ( JTAG) .
The solution that i want to explore is trying to revive the phone with the SD card.
http://forum.xda-developers.com/g4/development/unbrick-lg-g4-h811-9008-qualcomm-t3456417
http://forum.xda-developers.com/g4/development/unbrick-lg-g4-h815-9008-qualcomm-t3452853
The H811 dump that i made has TWRP recovery and unlocked bootlloader, so if someone know how to help that would be awesome.
How ???, its very simple. I dont have very good UNIX architecture skills , but if the SoC successfully booted from the SD card. We could see if it detects the EMMC memory ( with parted or with LS command). I personally Tried to brow /dev/block directory from TWRP i hoped to find MMCBLK1 or something but that was unsuccessful , im pretty sure the TWRP or the Soc Does not mount it automatically .
I really dont know How , but i'm very Sure that there is a Solution headed that way , So if some one is Good with Unix architecture and can find a way to soft Flash the EMMC from TWRP ( installed in the SD card ) it would be very Nice
hi,i tried the sd card method...it boots but immediately gives me secure boot error (1006).
i have an h815 bl locked
Hello
I have LG H815 and have bricked. I have installed wrong firmware so it is brick now.
I try new tot file with QPST . but it says fail what s wrong with me?
My computer is win 10 64 bit
You can fix fastboot mode with this way.
1. First you need to download stock rom that your phone supported. extract laf.img file from rom and copy it into fastboot directory
2. download LG Flash Tool and make it ready
3. open flash tool and load firmware and dll that support your model.
open command prompt and make sure you in fastboot directory where the fastboot and related files are stored.
Run following commands.
fastboot erase recovery
fastboot erase laf
fastboot flash laf laf.img
fastboot reboot

Hurry up, now you need to start flash with lg flash tool, if device does not start into download mode. remove battery and insert again, press and hold Vol Up btn and plug USB cable it will boot into download mode. and your device com port should be 41, if not change it in device manager. and start LG Flash tool to load stock rom. once it finish loading rom your device will start and will show you factory test 1, 2, or 3. if it stuck there more than 3-5 minutes. reboot your phone. now you will have welcome screen.
I hope this will work with supported models.

lol, when you see a screen with 0% and a usb connected image, that mean your battery dead
why not just try to charge your phone? or replace a battery?

Hello, well after what happened I thought the same and went to buy another battery and when they tried it did not work, I repeat, not fastboot, no logo, no recovery, only a small vibration without screen, it is not detected by the PC in any of its modes as dead, the detail is that this happened after restarting when I had flashed bootloader N, rom V30, magiistic, I gave it restart and it did not turn on again, so I discard that it is hardware .
I think the problem was that I flashed the bootloader with full aboot, that gave me hardbrick I was told in a forum in Spanish I leave the link I hope you help me thanks

Hey MichaelCV
I have exactly the same problem with my LG G4 H815p. I was running [ROM][H815] H-ROM G4 NOUGAT [v29a] _ LG G4. The phone was up and running and last night I flashed the "LG-H815_29a_Modem_and_Bootloader.zip" to try resolve an issue I was having with the mobile data indicator not showing. I flashed the zip in TWRP, rebooted the phone and now it is bricked. I have exactly the same symptoms as you. Windows and FWUL does not see the phone, no matter what combination of keypressed etc that I try.
Lets hope we find a solution here for it.

LG G3 in download mode not detected by Windows

Dear xda-developers-community,
I'm trying to get a phone of a friend of mine working which just reboots whenever the phone is started. The resulting boot loop can only be interrupted by taking the battery out or wait until it is depleeted.
In order to fix this soft-brick I first tried to use recovery by pressing VOL - & POWER. In the menu, I could select and confirm to recover to factory settings, but after some seconds the boot loop appeared again with (seemingly?) no change having been made. The error kept appeaing over and over again.
After trying recovery mode, I attempted to start the phone in download mode by pressing VOL + on the (switched off) phone and connecting a USB cable. The respective menu also opened, here, showing "Firmware Update" and "Do not unplug the USB connection until the process is complete". According to many tutorials I found on the internet, when having installed the required drivers (I used LG United Mobile drivers from here), this procedure should allow you to flash a recovery image through LG's flashing tool (which one can also find on that page).
However, when I connect the LG G3 (D855) to a computer the driver is installed on, there is no new device shown in the Device manager. I tried this out with Windows 10 x64 and Windows 7 x64 and disabled driver validation on both systems and enabled test signing on Windows 10, respectively. Additionally, I followed these instructions, but in this case the screen stays dark and the device is not detected either. It seems like there are not so many people experiencing this error, but I hope we can find a solution.

This may sound like a dumb question, but have you tried a new battery yet? If it is one of the original batteries it could have gone bad & started bootlooping...like mine did a few months ago.
As far as the PC not recognizing the phone you can try downloading USBDeview and uninstall anything that has the vendor ID's of 1004 & 18d1(pretty much anything that says android or LGE in the description) & reboot the PC. Hopefully it'll recognize your device and install the drivers the next time you plug it in. If it doesn't find the drivers automatically for you then install LG drivers manually.

Good luck :fingers-crossed:

You're still soft bricked, just force your device into download mode and use LG Flash Tool to return back to stock and start again.

If I remember correctly (please check threads here, it's been a long time since I've used this device, so memories are fading), download mode is activated when you press Volume Up (or both of volume buttons) and insert USB cable. I know that E98x has some strange button sequences, like rebooting to recovery is a two step operation (Volume Up + Power until navbar blinks, then power button twice, that's the only way mine wanted to boot into recovery), so please check around.
As far as USB connection issues, don't use USB3+ ports and if you're on Windows 8.1+ and later, run with Administrator privileges. I never experienced that one (used LGFlashTools from inside VirtualBox running Win XP for all my needs, I'm not a Windows user), so can't really help much but forums are full with explanations how.

Thank you very much...now the phone is back to initial state. This what i've done:
1. Download LG Flash tool from http://lgflashtool.com/
2. Download LG USB Drivers from http://lgflashtool.com/
3. Install LG flash tool and LG USB Drivers
4. Plug usb cable to phone
5. Hold volume buttons and then plug the usb cable to PC (i use win 10)
6. Voila, the Download Mode icon is showed up
7. Run LG Flash Tool (Administrator privilege) & follow the instruction (i use e988 v20c stock firmware)
8. Phone back to normal (only if you use the correct stock firmware)
A very big thanks to ShadySquirrel
Hopefully this thread can also be used as reference for anyone who has the same issue as i had
