My device is rooted with towelroot, I installed supersu afterwards...
before bootloop I installed fontexplorer, and installed few fonts, it asked me to reboot, i rebooted, and now it just bootloop's all the time, LG animation and vibration, I can't get into fastmode, tried all kinds of button combinations..
When I try to factory reset, after pressing yes it shows erasing, and then it's stuck on boot logo, not animation..
Download mode is stuck also, just shows 0% but at least then pc's device manager shows com device found
How to fix this ?
All this happened after I rebooted my phone, before rebooting I installed few fonts with Font Installer ★ Root ★(com.jrummy.font.installer) app
THIS guide will help, you've softbricked, only in this guide you will of course need the dll and tot files for your phone and not Sprint. As long as phone comes on,computer recognizes it, and, it goes into dl mode, you should be good.

I've been using iFont and Fontster from the Play Store without any issues for future reference.

G3s to me are finicky about changing or modifying. I modified one build prop setting, rebooted, same thing as op, mine wasn't bootlooping tho, but stuck on the big red 2 screen. Flashtool is your only friend at this point.

Wow, I can't believe I fixed it, I thought it's impossible
I just went into download mode and used LG Flash Tool 2014 to flash to stock firmware..

I think I read back when I was unbricking that .KDZ files have to be converted to .tot, to use with this version of Flashtool.
Quick Question
Hey guys,
I am a bit of a rookie with rooting and i have an LG G3 for tmobile. I rooted my phone and had TWRP installed and accidentally attempted to install a software update and it soft bricked my phone. Here is my problem-all of the solutions i am finding for this issue require a PC, and I, unfortunately, am only running on mac software. I have no way to get lg flash on my mac and to make it comparable with my phone. Is there ANYONE who can help me? I am at my wits end and CANNOT believe I was so stupid as not to make a backup flash but I, as per usual, did not think about it at the time. If anyone could help me, I will be forever in your debt.

I believe you can run virtual Windows on a Mac, not sure if it works with Flashtool though.

Unable to boot my rooted LG G3 S (beat), stuck at lg logo.
hello everyone. I recently rooted my lg g3 s (beat) D722K. After a few weeks I was trying to install apps as system apps using ES file explorer for which I had to copy the desired apk in the system/apps directory and restart the phone. it worked for a few apps (which I successfully made sys. apps) but not for a majority of apps . Everything was fine until now . After that I wanted to normally install an apk but the phone was unable to install it showing ' application not installed' . Then I tried to install other apps but got the same result . I decided to reboot my phone but it got stuck on lg logo and won't boot .
I tried to factory reset it using hardware keys but after wiping all the phone data it again got stuck on the same sucking LG logo .
I also tried to update firmware by connecting it to windows(8.1) pc in download mode which didn't work either. The firmware download got stuck at 0% everytime I tried.
please help me in getting out of this issue . I will heartily appreciate any help regarding this issue.
thanks.. in advance.
Hey all,
I restarted my phone yesterday and it was stuck in a boot loop for some reason. I tried to factory reset, but doing so still resulted in a boot loop. I then proceeded to attempt to flash stock, but the flash tool crashed while during the process. When I try to boot to download mode now, I get "Secure booting error, Error!: Boot Certifcation Verify". I know this also happens on the G2, and I know the process for fixing it. But when trying to use the same method with the G3, I can't access my filesystem from Linux. Any help? Thanks.

I was rooted before updating to lollipop, then tried to back dowk to KK with TOT and this happened, so I dont think I am rooted any more.
The better question is: do you have TWRP (custom recovery) installed? If you do, your phone can be fixed. If not, you are probably screwed.
Basically it sounds to me like your phone managed to flash the updated Android 5.0 bootloader but didn't update the LAF image (download mode). The old download mode doesn't work on the new bootloader, it gives the error you are experiencing.
Because you still have a LAF partition, and presumably a recovery partition (even if they are not working) you cannot access fastboot mode.
In other words, there may be no way to fix your situation.
As the hardware is fine there must be a method, but it might be something only LG can do.

I'm in the same situation now.
I was bumped with TWRP and CM12 installed. I wanted to unroot and go back to stock. Started a flash with LG flashing tool, but it was taking ages, so I unplugged the USB cable in the middle.
Now whenever I boot via either VolUp+USB or trying to get into a recovery I get secure boot error.
Is there a way to fix this ? Or do I need to send a phone to LG ?
This has happened to me today. Downgrading got stuck at 3%. LG Flash tool said to remove phone and plug back in. Any way to fix
Also, does anyone know if downgrading voids warranty or anything?

I didn't find a way to fix it, so I've just sent it to LG repair shop. They haven't yet looked at it so I don't know how much would it cost.
People just tell the service center that you were upgrading from KitKat to Lollipop when the problem happened
Evidence wise it support your claim since the OTA from KitKat to Lollipop overwrites the aboot, sbl, laf and recovery partitions and service center people ultimately cannot tell between failed OTA and a failed KDZ flash

solution for no download mode
Hi guys.
If you cant enter into download mode then you need to force your g3 in to qhsusb bulk mode by shorting the test point.
When you short battery must be removed.
After short your phone will be detected as qhsusb bulk mode.
Send me msg in pm for further help.
If u dont know the test point then let me know.

Hi! I just recently bricked my LG G3 D852, and I would really appreciate it if you could PM me and help me out here.

Try this. This will revert to factory default, tons of bloatware included ?
Sent from my D855 running CloudyG3 2.3 with Gabriel5 kernel.
Don't forget to smash that thanks button if I, or someone else helps you, guys!
First of all I want to Thank cybertag (a member at reddit.com) whose help made me find this solution. And sorry if my English is not good, it is not my first language. As I don't have enough posts here, XDA restricts me to post external links so this is the best I could do. I will add links to the files needed once i am allowed.
A few days ago I was tinkering with after my lg g2 ls-980, the sprint version of lg g2, rooted but no custom recovery installed and I made my first mistake of changing the model number from ls-980 to D802 in built.prop file thinking that it will only change the model number shown in the hardware information and restarted the phone. Once my phone booted up after that restart everything was crashing. There was a huge number of crash reports popping on the screen and I was not able to use anything. So I downloaded the .tot files of the stock firmwares LS980ZVC and LS980ZVE (don't know why but I downloaded both) along with the .dll file needed to flash the firmware for ls980 and when I tried to flash the firmware booting the phone in download mode and using the LG Flash tool but it gave me an error saying that the firmware does not match with model number of my phone. Both firmwares gave the same error. My phone and the flash tool both were thinking it was D802 while it was not.
Now i made my second mistake and downloaded the stock firmware for D802 and flashed it using LG flash tool. The firmware was flashed successfully without any error, but when the phone booted up after the flash the touch screen was behaving funny and phone restarted every 15-20 seconds because this firmware was not meant to be used with LS-980. I was unable to do anything the way touch screen was behaving.
I spent most of my time for the next few days googling for the solution and searching on XDA and also on reddit. I found multiple threads reporting that a generic no-check DLL file is the savior in this situation, but when I tried to run it I get continuous errors telling me the following: "CrossDL [D8012] to [LS-980]". Then i found this thread by cybertag on reddit which lead me to the right direction. It suggested to hex edit the .tot file for ls-980 so that the flash tool thinks that it is for D802. So I grabbed a hex editor and found the first mention of LS-980 and changed it to D802, saved the file and tried o flash it but it was still giving different errors. Then someone suggested it only works if you edit the .tot firmware in linux based OS. So i installed ubuntu OS on a virtual machine and tried editing the firmware in that OS using Bless Hex editor, still no success in flashing. Then I tried editing in pinguy OS but in vain. Then I found FlexHex for windows and used it for editing the LS980ZVC.tot firmware did the same thing, found the first mention of LS-980 and changed it to D802, saved the file, flashed it and bingo! the flash tool gave no error this time and flashed the phone successfully.
Now there was another problem. When the phone rebooted after flashing the firmware it got stuck on LG logo forever. And when I tried to boot it into download mode, the download mode was gone and it took me to fastboot mode. The phone was stuck in bootloop and there was no download mode anymore. Now after more searching i found a method to resolve this problem. Downloaded the aboot.img and laf.img partitons for LS980ZVC and flashed both using fastboot commands. Tried to boot into the download mode again and it worked and i was in download mode one again. When I checked the phone model was changed back to LS-980, the original one. Flashed the LS980ZVE firmware from original .tot file as it was the latest version available to date and it flashed without any error. When the phone rebooted after completing the flashing process, it was as good as new, up and running the original stock kitkat rom for this model. Tested and tried everything and never noticed any issue.
Thank you @tauheed that will help a lot of people I'm sure.
Thank reddit member cybertag out there to.

the only possible option is to flash the aboot.img and laf.img partitions. But we need to find a way to do so in your phone's current state. Things can be a lot easier if you could manage to get into fastboot mode.

more info is better than none, what did you do to "accidentally brick" your phone? and if you are stuck in download mode you could try the lg mobile support tool and re load the rom for your device.

READ completely, including the link in 4 before starting!!!
download the tool using the lg d851, under t-mobile. the tool is generic, and can be found at lg.com under support/downloads
1. install LG Mobile Support Tool
2. run Tool, it will query lg for updates and do so if needed.
3. Install USB Driver (dismiss if you have done so already)
4. follow this process: http://forum.xda-developers.com/showpost.php?p=51268802&postcount=21 (use 5. below to put into download mode, not vol up and down like the link states)
5. with your device off, hold the volume up button while plugging in your USB cable with the Tool open.
6 you system will recognize the device and configure drivers, this will take a minute.
7. continue following the link in 4.
I ran into the same problem and now i'm stuck in downloadmode!
Does this method work? Or is there any other fix yet?

hey guys, don't ask for a different fix if you don't bother to explain how your phone got stuck in download mode. as for does this work? Why don't you try, it's the same tool used to upgrade firmwares instead of using OTA, and the link included shows how to get the tool to download the file (if it sees the same/current f/w it does not download the firmware) and you have nothing to loose, and this method is often used to recover from "soft bricking" your phone.
i was restoring my LG G3 to stock through the lg flash tool .....when i got through with it and restore was succesfull. somehow i forget the usb cable plugged through my pc usb port ...then connected my lg g4 that is where the flash tool got my Lg g4 on Downloade mode ....i tried all the methodes somehow i think the recovery is messed up .....i can get to the recovery through the button but it reboot straight to the download mode ....thanks every one for their support

don't think it's out yet, however my statement was somewhat incoherent. I meant to say if he had the kdz, he could use the flash tool to recover his phone.

Yea, at this point there no way to fix this without a kdz that I know of.
Call LG and tell them you need the kdz to restore your G4.
i was lucky, i had flashed twrp before my phone soft brick..

I got an LG G4 which is stuck on lg screen. When I put it in download mode, it shows download mode for a few seconds and restarts. I was trying to flash ZVB over ZVD and it ended up like this. Model is ls991 . Any help would be really appreciated!
Anyone got any idea? The whole thing started with getting rid of the Genisys rom ... I did not like it ... I thought I was going to bring it back to the stock, but then LG Up wrote an unkown device ... I thought it was flash with lg bridge ... that's what I lost. .. has removed recovery and has stopped updating at 16% ... since then it is only download mode I tried to update but failed with all three programs ... LG up to start - unkown device, LG bridge stop at 16% , LG Falsh Tool 9% ... sorry for my english
Hello, (complete n00b here)
Several days ago I've tried to flash a 6.0 MM (from 5.1) to my LG G4 H815 phone. There was no option to do it automatically so I proceded to do it manually via flashboot.
I hard-bricked it to oblivion as in black screen, no response whatsoever.
While investigating @ the internet I've managed to understand I could get it fixed via quadcomm drivers (mode 9008).
Tried various "fixes" for H815 but was getting safari download errors. For some reason I tried a LS991 fix and it worked. When I started the phone it showed no logo but just a secure booting error 1006.
Still, could enter firmware download so I began to flash a lot of KDZ firmwares with no success.
LGUP shows my model : H81510H.
While in fastboot mode there is a note below (wasn't there the first time) with codes : 633 B46 or something like that.
While flashing anything it ALWAYS STOPS at 9% with a tot anti-rollback error. While flashing the code changes briefly where one can read smth like : LGLS991ZVA ver. 6.0
Managed to download some KDZ for that exact model, SAME ERROR. Tried to find / flash LS991ZVA with no success in finding a TOT file.
Also, managed to get ADB drivers up and it shows unauthorized in listing (LS991). Fastboot does not detect my device even in fastboot mode @ phone.
Please HELP!

H81510h is os version it is still at 5.1 I think....what may help is plug your phone in with lgup and drop the battery out of it then closes of LG up put battery back in and start LG up and find kdz that matchs your phone and make sure that it doesn't have anti rollback.....

Hello and thx for reply. I tried to do what u've said. It did something (I was looking for a while back). When I plug the cable back in, my windows 7 immediately installs quadcomm hs-usb driver (9008) and my phone acts as if it was dead. LGUP cannot find it in that state. I've been trying to QFIL the "proper" soft but it continues to pop different errors (using different QFIL versions). Either saharafail or some sort of download fail.
LGUP still presents an error (if I decide to "fastboot" it) @ 9% 0x2000, TOT antirollback version is smaller than device version.
How can I make sure I've got the proper KDZ without ANTI-ROLLBACK?

Thx again. Uppercut shows H81510H as LGUP did. Is it possible that it's somehow write-protected?
It confuses me, since during the firmware update on my phone, I get this small box below the picture showing wierd codes : 633A Bxx and when I'm trying to flash my phone, the code gets longer with LS991ZVA v6.0 and more other. It then stops.
Funny thing is, when I got the phone I couldn't even connect to the LG bridge to update it at all. I've managed to do it bugging the MTP protocol but THAT on the other hand prevented me from copying stuff / FLASH my phone to MM 6.0. Had to factory reset it back then and all went back to "normal" = LG couldnt detect my device but I could copy photos or stuff from it.
NOW, when my phone is bricked, LGbridge DETECTS my phone (in fastboot), downloads the newest KDZ update BUT cannot install it (same thing as in LGUP). Hence my question : is it somehow write-protected?

Have you tried to eset it by pushing power and volume own then when you see bootsplash then release power button and hen quickly push the power button again....
But in your case push power and volume down within the count or 20 then release power then push power button again and see what happens and then try the same thing on volume up......
Thanks for the reply.
I did what u've said. Despite no logo I tried to release power button for a second just after the screen's brightness goes up (I also get a small vibration @ start). Everytime I get secure booting error 1006 after a few seconds.
On the other hand when I did that with volume UP button there was no error but there was nothing aswell until I release power button in which case I got the secure booting error. All of the above tries were done with no USB connection with anything.

Do try with usb s well it may do something r do nothing......
Can't tell atm since I gave it to professionals. I'll wait and see how it'll turn up. Thx for all the effort tho, was nice to tinker with a lil help
@Longbranch did you solve this problem ? I'm in the same state but my phone model is H810, everything else is the same as yours.
Nope, not really. I gave it back to the reseller and my money got returned luckily.
The professionals I refer to above did install a specific firmware for the ls991 type. Firmware ZVB I think. The only one appliable apparently. Anyways, as I suspected the ls991 type is for the US and therefore it didn't work in my country in EU. My sim card wouldnt work with it. Besides, without the sim card, the phone decided to freeze and die after several minutes every time I turn it on. Swapped for LG G5 and it's working flawlessly up until this day.
good for you, what i don't understand is that it's a h810 model but now identify as ls991 does that mean you can convert it just by a Qfil flash? I may try another model flash if can't find a suitable Rom for it

Yes! That's what I and neutrondev telling everyone :
do not use qfil without the knowledge about the result!
The only working firehose file available out there is for the ls991 and that means if you use it it will turn your device into a ls991 without any way to get back to your previous device model!!

@steadfasterX since I have done it already is there any way to get it working even as an LS991 ?
here is what i did till now
the reason for using Qfill is that it went dead after flashing an H810 rom .
after that when it's in download mode it doesn't allow me to flash the ls911ZV5 ls911ZV6 ls911ZV6_12 roms that i found ( it says LS991ZVA )
so i went in fastboot and flashed boot/aboot/recovery....img extracted from the ls911ZV6 rom then it accepted the rom in download mode
but it is stuck in a hard bootloop ( reboots when it is getting in recovery but still has download mode yet no fastboot as before)
any thoughts ?

Yes it's possible. You can boot a h811 H815 or any other rom you like. Even LOS!!
Great right? BUT you are bounded to the ls991 modem and so you need to be in a sprint network to use telephony. That means the phone is now useless outside the US .
And you wrote you tried ls911 ROMs? I hope you meant ls991
I work on a fully working experience on every network though. Checkout my proof of concept for unlocking the bootloader thread
I can go into details on IRC if you like.

@steadfasterX thank you for keeping up with me ! ( btw what room on IRC ?)
for now I have used Qfill again and got fastboot working again and flashed TWRP ( not sure where ! ) so when the phone is off and i plug the usb it boots to twrp ( but it doesn't in recovery )
normal boot will show "secure boot error 1002"
then i flashed twrp img to recovery partition using twrp but it didn't work in recovery ( still reboots after showing Recovery Mode loading screen )
also tried to load some roms on the device to try them but I got error "file too large for filesystem " when copying them .
atm I don't know the state I'm in and what should be next ?
btw here are the recovery log and dmesg

Np we can bring you back to life but as already said without cell service. That's the price for the firehose and unlocked feeling you have now.
Did you found and read my thread here?
https://forum.xda-developers.com/g4/general/bl-unlock-unlock-bootloader-proof-t3648288
There you will find some more info and also the IRC details how you can find me. I'm online from Monday to Friday mainly.
It's much easier to talk in chat then here. once all the details are known I will provide a full guide.
