Hi!
I recently bought an LG G4 from an online seller. The cell phone itself is working fine, but it has some problems. It is a refurbished model.
I will very much appreciate any help.
The cell phone is actually a F500L model (I checked it by looking at the motherboard), but in the software information it shows to be a model H81510h.
The phone is not rooted. But I believe that someone did it, changed the device's descriptions and then uninstalled it.
It is an android 5.1, but I cannot update using the update center. There it shows that it is already in the latest version.
In the developer settings, I try to enable OEM unlock, it activates for 1 second and deactivates automatically.
I try to do the hard reset, but when restarting to start the process, it presents an error "Secure booting error 1002".
I can activate USB debugging, it is recognized in ADB tools and I can send commands to it. But it does not start the bootloader with the command "adb reboot bootloader", and it presents the same error "Secure booting error 1002" if I try to send the command "adb reboot recovery".
I can activate the Download mode (by pressing the VOL UP button and inserting the USB cable), but it is not recognized by LGup (UNKNOW / COM5 H81510h), LGup does not let me work with it.
In the LG Flash Tool, it does not start the flash process, when it reaches "BIN CRC Check" it presents the error "Failed PreviousLoad0". (I already changed the port to COM41)
In LG Bridge, it is recognized as F500L and shows that there is an update. But when trying to update, it does the first steps, but after the download, when installing it gives an error and asks to start over.
I have tried to use UPPERCUT_1.0.0.0, without success.
I do not know what else to do...
Any help will be appreciated.

Hello all,
I've done a lot of googling and searching on these forums and I'm having no luck. Hopefully by asking I can get some headway.
I was attempting to restore to stock rom. At 17% of the process using LGFlashTool 1.8.6 the tool gave me an error 'Unable to Communicate with phone' after about 10 minutes of no progress. I exited the LGFlashTool program and ran it again and now it fails saying 'Cant' change to download mode". If I turn the phone off and then press Vol+ and plug in my cable it just goes to the Firmware Update screen. My phone *IS* detected properly in the device manager as LGE Andriod MTP Device and under ports as LGE Mobile USB Serial Port (COM41). If I go into recovery (Vol- and power) it asks if I want to do the restore - but it doesn't actually do anything once I say yes twice. Just sits at the firmware update screen at 0%.
I looked at this post (http://forum.xda-developers.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091) but it appears to be either for a different phone or different problem (showing in device manager as a bulk device - mine is not doing that). Frankly I don't want to make things worse (if that's possible)
Does anyone have a way that I can restore the download mode for this D852 phone? I'm hoping if I can get download mode to work again I can reflash the stock rom. I don't care about the data on the phone at this point.
I'm willing to send some $$$ via paypal to whomever can get me back up and running! Thanks

What happens when u just power up the phone ?
Thanks for the reply.
If I shut the phone down (by pulling battery) then plug it back in and just power it on, I get the LG logo then it goes to the firmware update screen with 'USER B84" in the box below the progress bar. Progress bar never moves. I get to this screen whether I start it in recovery (which is just the factory recov - looks like during the initial 17% it wiped out my TWRP), attempt to start it in download mode (I do not get the download mode screen with the blue dots anymore), or regularly by just holding the power button.
ok
Dont plug it into the computer and try to power it up what does ot do?
Same thing.

Ok that didn't work for me but I did try the LGFlashTool using Board DL instead of Upgrade DL and it was moving a bit. Finally got to 10% and failed at 574 sec with the error "We can't communicate with Phone". I am using the cable that came with the phone. It isn't damaged or anything.
Here's what is shows in the LG Flashtool window (this is port 1 (com41)
Code:
PID: BS09S150309001007
IMEI: <myimei>
Model: D852

On the phone it shows COM41 under the usb icon on under firmware update and 0% progress. In the box below it says:
Code:
F USER 50.0 A50.0 B70 UHS
S U LG-D852 04.4.2 Hrev_10
D85210b
D85210b
That's it. Should I leave the phone connected at this point or unplug it? Device still shown in device manager (have had it up beside the LG Flashtool window the whole time. I do see it refresh from time to time but the contents dont' seem to change at all.
Ok so I left this over night and when I checked the phone this morning it's different but I don't think it's good.
Looks like it proceeded but ended with:
FBOOT Check
FBOOT Complete Time [0s ] 1th try
Factory Reset Flag = 2
Factory Reset Flag Check Fail!!!
And my phone has a blue screen with Factory Reset Status and a big red '2'
Now what do I do?
Some further information.
If I run the LGFlashTool in Board DL action mode, it seems like the process works but I end up with the red 2 on the screen. But I don't get 'can't change to download mode' or 'cannot communicate with phone' errors.
However if I choose Upgrade DL action mode, then I get 'can't change to download mode' or cannot communicate with phone'. ARGH. What gives?
I have tried things like fresh restarts (restarting PC), restarting the LG FlashTool between attempts, not restarting flashtool, etc. I can't seem to find the sweet spot.

http://forum.xda-developers.com/sprint-lg-g3/help/fix-bricked-lg-g3-ls990-stuck-fastboot-t3084562 another tutorial to try
Thanks, but no dice.
I don't get fastboot options, and if i download and attempt to use fastboot, it shows no devices.
Also, when following the steps for the BOARD DL option in the lg flashtool, it goes through the process but I get no ATT screen. Nor do I get the option to tap OK or Normal - as soon as my device reboots after the flash, it gives me a MINI OS (iirc) screen with a bunch of vertical bars below it moving up and down then it changes to the Factory Reset screen with the number 2.

Thanks - I'm going to give this a try, however I can't finda .kdz file for my phone (canada/rogers D852 LG G3) - the links in that post that link to firmware is for a tot file. Does anyone have a link to the KDZ?
Hi, I'm having the exact same problem now, where the phone only boots to the Firmware Update screen. Did you manage to fix it?
Indeed.
I used the KDZ method pacods61 posted last, but I had trouble actually finding kdz firmware. With some help I finally managed to do so from here: http://devtester.ro/projects/lg-firmwares/country.php?country=Canada

Hello,
I seem to have really messed up my G3 and after days of research I have not been able to get anywhere with it. I've read posts of people having similar issues, but their solutions do not seem to work for me.
What I tried to do is flash the ROM, starting with TWRP. After installing TWRP and rebooting I was getting the "no command" message on the screen. I believe (this was days ago), I used ADB to remove laf and reboot the phone (for some reason I could not back it up). The phone rebooted in fastboot and it has been downhill from there.
No download mode. When normally started the phone just hangs on the LG logo. Vol- and power gets me to the "Factory data reset", but if I do that, it flashes "erasing" for a second and it goes back to the LG logo screen.
I can get to fastboot, however, any command that I enter in CMD or Linux terminal just shows up on the phone's screen and it does not do anything. Fastboot devices shows the device as "????????" in Linux and as "?" in Windows. I have tried multiple drivers for Windows.
I tried BoardDiag (3 or 4 different versions running as admin) and shorting the pins, but any time I try to run the checks, I get an error - "No response from device" or "Device was not found in dload trying flash programmer"
I also tried SmartBootDiag, but once it detects the phone, it does its checks and it disconnects the device, without giving me an option to flash anything. Looking at the logs, it does not find any anti-rollback issues.
Any suggestions would be greatly appreciated as I am not sure what else to try.......
Thank you.
Anyone??
Help please..My Lg G4 H815 is stuck on infinite loop since yesterday..
Just shord to be in words...My phone was stuck on lg logo after the battery whrn dead and then boots up and on the type the pin he restarted over and over, and i tried to reflash with LGUP and at 17% my phone restarted just like that..

I can't enter recovery(stock one) but when i him yes the second time to erase the error shows up and restarts.
Use the search option. Not for me and not for anyone else but to help yourself as fast as possible. You'll also learn stuff.
XDA user roopesh had the same problem: http://forum.xda-developers.com//g4/development/stock-h815-20a-stock-rom-t3233049/post63721579
He/she fixed their problem by following this guide: http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
Or follow my guide:
i) Make sure you have the LG Drivers installed from here: http://oceanhost.eu/e4h2px4e0hkd/LGMobileDriver_WHQL_Ver_4.0.4.exe.htm
ii) Download the LG Bridge software from here: http://www.lg.com/us/support/product-help/CT10000025-1438110404543-preinstall-apps
iii) Remove the battery and reinsert it so the device it is fully off.
iv) While holding the up volume button, insert your USB cable.
v) You should enter download mode. Go to the Software Update tab of the LG Bridge. It will say connecting and then should say your device is up to date. Click on the recovery text on the bottom right and then follow the instructions. The software will download the system image for you and this is roughly 1.6GB so make sure your firewall doesn't block this connection.
I've searched everywhere i think..before i posted the question
The phone wont stay in download mode....
It shows the little box with download and then the error i mentionet above and restarts..
And means SEA mobile?
hey alex have you fixed your g4 ? i have same problem.
Hello Gurus,
Well i am trying to boot my phone into download mode but i am continuously getting
secure booting error 1014 and my phone then boots lollipop 5.1 which is stock rom.
my lg g4 model is h81510h build number lmy47d, it is not rooting or flashed anyway.
I want to flash flash marshmallow kdz with lg flash tool but my phone is not booting into download mode, please help or suggest any other method
HALP PLS
I'm having more or less the same problem. I bought a used H815 and it came with Android 5.1 (software version h81510h)rooted and stock recovery. I tried upgrading to MM over OTA but tapping Update Center leads me directly to the App Update screen instead of giving me a choice between software update and app update.
That is when I decided to go the KDZ route but when i tried switching the phone to download mode it went there and in the top left corner there was this 'Secure Booting Error 1014' message and then it restarted in about 5 seconds. I have tried this multiple times with the same exact result.
ADB detects my phone but when I send the 'reboot bootloader' command it just does a plain reboot so I can't use any of the fastboot commands. I also have no idea whether this phone has an unlocked bootloader or not.
Also for some weird reason my phone is not using the MTP mode when I connect it to my PC. It either uses PTP or charge-only depending on what I select but if I select MTP it automatically reverts to the previously selected mode. LG Bridge doesn't detect it and neither does the Mobile Support Tool but I can transfer images just fine. MTP was working last night but it suddenly stopped working and I have no clue why.
I can get into the recovery without any problems.
Please help me get it working again

Any update ? I am also facing same issue. One wierd thing I noticed that adb devices displays phone as "LGLS991" can you tell me your result of adb devices ?
Im having the same problem.
Lg bridge, lgup and flashtool not detecting my phone. How to flash my phone with any os? Kindly help me
Same problem with my H811. Any solutions?
I cant get my g4 into download mode. I was able to earlier but it died on me. My buddy has the same phone so I am using his fully charged battery now (mine was around 40$) but I'm still getting nothing. Should I reformat the SD card and try again? I can't think of anything else.
Hello i have tried many times to unlock my lg g4 bootloader but every time i have tried i get towards the end (fastboot flash unlock unlock.bin) its says "waiting for any device" although i have installed and updated every single driver required its keeps giving me the same problem
any help would be awesome:good:
Hi, did You try this tool https://forum.xda-developers.com/g4/orig-development/tool-universal-fastboot-adb-tool-t3475834 ?
Are you sure that you are in fastboot mode on your phone? That you have "unlock OEM" marked in development tools?
Check that you do not accidentally enter bootloader mode.
Greetings
Same issue here, and "unlock OEM" cannot be activated on the device Developer mode.
This issue is with a "H815 20o" (MM 6.0 as stock rom, refurbished Ali/Ebay model from China).
So no access to Fastboot (but device is detected by Adb with "Adb devices" command).
And flashing many KDZ or TOT files with LGUP or LG Flashtool always end up with a fail/error message at 9% of the process.
(And LG Bridge doesn't update anything too : "your phone is up to date"...)
If somebody got any solution... Cheers.
