Hello there pals, I have a problem, I have an Lg H815P (Mexico Version), and i was using it normally for about 15 days, then suddenly the home screen freezed, and then the phone restarted, i thougt it was just a lagging issue, but then, when the phone booted up again, after like 5 secs it freezed up again and restart, a infinte loop, then i said, this Rom must be corrupted (Stock TELCEL Rom v20b Android MM), and decided to do a hardware keys factory reset, then the phone restarted but when it was android upgrading apps, it kept restarting, at last it booted up but the problem persist. So im kinda worried, how a problem cant be fixed at a full hard reset? When im trying to flash a KDZ file From lg flash tool, the program fails because cant find phone, a kinda weird thing because the adb detects it sometimes, others not, i booted the phone in safe mode and the problem persist anyway, what can I do? I already have the drivers, the lg up, and the lg bridge apps, they all said that im running the last software for my mobile device, i´ve tried another battery as well, so im kinda lost, another thing, after the hard reset, the phone was able to stay on like 15 mins, sometimes 5, sometimes just secs, dunno what is happening but i really need some ideas, can you help me to work this out?
Greetings pals!

I have had this problem occur because of the launcher. Try cleaning the cache and data and see whether an updated version is available. You could also try a 3rd party one and see if that helps or simply re-install the LG launcher.
If no luck, you could try flashing another kdz with LGUP-NEW: https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
There are a couple of TCL kdz's listed on this site: https://lg-firmwares.com/lg-h815p-firmwares/
Scroll sown to LG H815P Firmware List.
Back up everything first.

Ty pal, I´ve tried with nova launcher, but no dice, still restarting, perhaps because i cant disable lg launcher from apps menu, actually i´ve been trying with flashtool and kdz files but i think the program doesnt recognize phone, cuz it show the message in lg mobile support tool: error required info cannot be found, contact administrator. I have the drivers, the pc in download mode and connected to pc, full charged, what else im missing?

Make sure you are using the correct LG Mobile Driver on your PC: LGMobileDriver_WHQL_Ver_4.2.0
If you are using the drivers your PC installs, you will have issues. Check in Device Manager on your PC.
Use LGUP-NEW to install a kdz.

I found the correct drivers and installed a DLL for lg up, so the program now detects my phone, the problem is that i install as Refurbish the same version that i was running, the h815p v20a, but when it finishes it says rebooting, but in the device is boot looped at lg logo and powered by android, the phne used to boot and show desktop, now is bootlooped, what else can I do to make him boot?

If the phone is still recognized on your PC, see if you can get into download mode. If you can, try re-installing the KDZ from there. Make double sure it is the same kdz that was installed on your phone when it worked.
The other option is to see if you can get into recovery mode and try a factory reset.
It is possible that the freezing you were experiencing before when it booted up was, as raptordd suggested above in post #4, an early sign of the hardware bootloop issue that has now manifested fully. The only real option then is to send it in to LG for repair and tell them your phone, you believe, has developed the hardware bootloop issue. Even if out of official warranty, they should replace the motherboard in that case, at no cost to you.

Now that u mention that, the phone was recognized by pc, but i installed a lot of kdzs, and none of them made the phone boot, every one of them were for h815p v20a, the one that was installed, but now i connect it to pc and then says download mode but doesnt enter and then the lg logo appears again, even the charge is meesed up now, i think i screwed the download mode and the charge mode, is that possible? but i tried the factory reset when i had the working firmware but the problem persists. Now im thinkin my only option is to use a octoplus box to revive it, but dunno if that will fix the restart problem, about that warranty stuff, i can send it to lg mexico and they should change my motherboard for free? That sound too good to be true.

See if you can enter recovery using the hardware buttons and try executing it again.
LG has been replacing motherboards in a lot of cases where the issue is attributable to their own hardware issue (ILAPO). You don't really want to discuss the things you have done to get it working again with them ... if you get my drift, i.e., play dumb ...

No luck at all, phone is still bricked, is there any way to flash stuff via bootloader or abd without bootloader unlocked or root?

Hi
I have a t-mobile D851 LG G3, for which i was trying to restore to STOCK software, through one of the guides elsewhere on the forum. My first try FAILED, and now the phone is stuck on the "FIRMWARE UPDATE - Do not unplug the USB connection until the process is finished - USER B51" screen
No matter what i do (all key combinations for recovery mode, download mode), plugging, unplugging the phone, taking the battery out for 30 mins or so, and putting it back - NOTHING is working. It all goes back to the screen mentioned above.
I tried running the LG Flash tool again, but it fails.
Any ideas? Any help would be greatly appreciated. This phone is my daily driver, and I am in a major fix without it.

EDIT - SOLVED
Thanks to everyone who chipped but especially to pside15 and one other person (but i can't find his post)
The solution was very simple - I was making the idiotic mistake of looking at just the computer screen and NOT the phone screen. The computer kept giving me all sorts of errors saying 'update failed - can't connect to server, yada yada' etc. I just left the phone alone - came back 10 mins later to working phone.
Moral of the story - Watch BOTH the phone screen and the computer while doing these things, because my computer had me believe that this is not gonna work - the phone obviously disagreed
When the flashtool fails, whats the error? Its not hardbricked if it still comes on and goes into download mode. Look at THIS image and see if you set action mode the same. This one mistake caused me a headache last night for 6 hours.
Your link doesn't work.

it doesn't come into download mode - its just stuck at the 'firmware update' mode at 0%
And does it matter that its a D851 (the t-mobile) version?

Uninstall drivers from device manager in computer, reinstall. Make sure to change com port to 41. Also board dl in action mode is a complete overhaul of firmware, the other setting in action mode is to update firmware.

If your phone can turn on an go into download mode you can flash it. Just try w different computers

I am not allowed to add the link yet.. Sorry
Type the following on YouTube
How to Unroot/Unbrick LG G3!
My Phone was up and running and I forgot to close the LG Flash tool on my PC. The flash tool started to flash my phone again, at about 80%, when the tool restart the phone , it never came back and since then I am sitting at the firmware upgrade screen.
I can see a yellow mark in device manager under Portable device.... I can see under port LG Mobile Serial port which i set it to 41. I read about something called wipe cache partition. I have used few different PC but it is not downloading the firmware at all.......... Please help!!!!!!! Can I use Linux ADB to flash the firmware .... Any tutorial ......
I have really searched and searched whatever i could but could not achieve any thing sorry for opening a new tread but i am really desperate for fixing my G.
So to start i was on Art Mod v7 and i saw that he posted a black theme so i installed it after installing some system stop responding what i guessed that it might be i didn't wipe cache, well i did that and got into soft brick, i am not blaming him for any thing it was all me , so i should have flashed new kdz but i didn't do that i flashed teenybin Files i dont know why i did that but i did resulted in a different kind of brick.
So problem is i have fastboot i have download mode but device some times get detected on download some times it doesn't when it did i tried flashing kdz through lg kdz flasher but resulted in continuous operation break also no driver is detected in fastboot and more over no recovery as it is in secure boot. I am a noob so please do bear my questions.
do kindly help LGOG is in continous bootloop more to add.
some what LGNPST detects phone in download mode the same application given with teenybin.
Kindly do help i know about android i just read silently but this time i am unable to solve it.
What system do you have on the machine that you're trying to flash the KDZ file? Did you install the LG driver?
I had trouble to flash kdz on my device from Windows 8.1 64bit. The flash would freeze after some time and nothing would happen. Try it maybe on another computer but after installing all the needed drivers.
Which software do you use to flash the KDZ file?
thank you for replying

I'm sorry but I really have no more ideas on how to help you. I did not have similar problems, I had a problem when my phone didn't want to boot anywhere except download mode. But the flash went through after a few tries.
Maybe you should try to flash it on a different computer? Install drivers and everything again and try to flash again. There may be a problem with drivers or something
I got it, done it

What did you end up doing? I've been trying for weeks to unbrick my phone i even took it to 3 cellphone repair guys in my town and no one knows how to unbrick it.
Please get back to me! Im stuck.
Hello so I am hoping i could get some help fixing my lg g3. Its been stuck in boot loop for a couple of days now and I've looked and searched and I cant seem to fix the problem. I don't know if its hard bricked or maybe there's a way to fix it. The issues all started when i couldn't connect to wifi or use Bluetooth on my phone. At the time i tried updating to 5.1 but was not available yet. I had seen on some threads that by downgrading it might fix the issue. So I downgraded my phone by using LG flash tool. I downloaded the dll. at&t D850 file and the at&t D850 tot file. Afterwards the wifi and Bluetooth was fixed. But then it started to reboot on its own and the issues came back. Although after a couple of reboots it just got stuck.
I've tried doing the factory reset by holding the volume down and holding the power button and i see the android logo but it s till gets stuck on boot loop.
I've also tried reinstalling kitkat with LG flash tool and when i do it says Fail Mino OS at around 90%.
I was also gonna try and use Odin3 which i read might fix it but when i connect my phone to my pc it doesnt recognize that its connected. I uninstalled and reinstalled the lg drivers but still cant recognize it.
If anybody could help me and give me some advice that would be greatly appreciated
Same problem here, did you fix it?
I got exact same problem, don't know how to fix it.
Possible solution (if u downgrade mm to kk and the result is boot loop)
hi guys
i tried to explain my solution (sorry for my english but i'm mexican)
i had the same problem like u, but my problems with this device start with the wifi and bluethoot, when i tried to turn on just doesn't work.
i tried the same method with TOT and DLL files (Kitkat) V10a and LGUP, LGFlashTool and LG Flashtool 2014 but nothing, the phone finish the flash done but the boot loop continued.
i search and read a lot of tutorials and nothing, but i found a KDZ for D850PR, this firm is from Puerto Rico but works on ATT Devices and vuala!! my phone comes alive!!
ok, u need some file but i think u have almost all of them....anyway i will explain everything than it's possible..
Files to need:

LG D850PR Firm V20a - http://www.easy-firmware.com/index.php?a=browse&b=category&id=314 (i will try upload to my dropbox and paste the link)
and here we go!!
1.- follow this tutorial to learn flash with LG Flashtool 2014 - http://forum.xda-developers.com/showthread.php?t=2797190 (thanks to quangnhut123)
2.-when u finish to flash the firmware, perform a hard reset
*HARD RESET - remove battery, press volumen down + power, when u see the LG logo release the power key and hold on again, and u do the hard reset.*
PD. *if ur device turn on with Mini OS 3.1 screen do the next steps
-check the options and u will see "normal boot (+ power key)", hold on the power and press on this option and the phone will starts normal
i hope help u with this solution, i don't know if this solution works in ur devices but maybe u can try and get back work ur LG G3!!

Can you put your phone into download mode? => Hold volume down button for a few seconds and attached the usb cable to your phone?
Also, how old is your phone? LG phones have a history of having issues with batteries dying and this causes the phone to constantly reboot. I had this problem myself, which is why I know about it..

In particular the part where you change your device to COM41 in the device manager.
After you get it discovered by LG Flash Tool flash an official KDZ.
Reboot the phone and connect it to your Windows, allow the connection from the phone screen.
It should promt you to install drivers on the computer, do that (they are different from LG Drivers you download from the web mind you)
Now you can change your COM port back to 3 and everything should be fully discoverable by both LGUP and LG Flash Tool.
I think I replied to you on reddit (same photo) Have you tried plugging the phone in while in download mode ? Did you try installing drivers from the internet ? Coz thats how I fixed the same problem you have.

You asked for other people's time to help you, but now you don't have time to explain how you made it work?
Yeah... there MIGHT be other people with the same problem, but why would you care to share.
What an as*hole you are. Another typical new buttuser ruining a great dev community.
exactly

Exactly, here I am running around in circles over this BOOST Stylo 2, just got it with MM 6.0.1 out of the box 2 days ago. I caught the 454.4mb update it has been trying to do! Got that baby downloaded! 1.02gb unzipped and renamed to kdz. Got a script for Terminal that will replace Kingroot's temp root with SuperSU but I am not going to attempt any further until I know LGUP will recognize and flash my .zip the bas****s deem not worth enough to put up for download on LG's site!
I got LGUP to recognize it in download mode, reads out LGLS775 but still says it cannot open it...............
His info on how he got it to work would prolly have solved this dillema..............
oh well
zach
ok had a LG G3 that's done this- as long as you can get download mode it should recover, YOU need to use the LG mobile support tool from LG website ( LG UP sees phone as unknown model ) run LG mobile Support tool and in option choose UPGRADE RECOVERY . follow instructions and allow to start process, it took 57 minutes to repair my phone - it will seem frozen anywhere from 0% to about 22% JUST WAIT IT OUT!! lg up / twrp flashes in 5 to 10 mins -- the LG m.s.t writes block by block and takes 1 hour +
so hints and info took 3 goes to find and start upgrade recovery - error on a couple of attempts. phone seems frozen around 10% and 15% of firmware upload -- go make a coffee drink it, go pee then come back and worry! A watched pot never boils!....

It didn't. It's EVEN MORE broken :'(
I figured out how to get my PC to recognize my D851. Apparently all the LG software didn't like how many COM ports I have. As soon as I unplugged everything else from my PC, the software worked. In this case, it was LG Flash Tool 2014, but I couldn't get any of them to work before.
Try running LGUP as Admin!!! For me it worked!

Hope someone can help me. I flashed a rom for a d855, d855g30 I think, and although I can access download mode all aps for flashing fail saying it's the wrong model number. Even the generic DLL file cant trick it. It still starts booting the rom but boot loops before entering. I no longer have twrp and when I try to do safe mode or factory reset I get a boot validation error or something similar. Just seem to be stuck. Im using a VS985.
One cause of LGUP "UNKNOWN"
While an old thread, it'll be found in searches. For anybody who gets "UNKNOWN" device with LGUP for the LG G3, I found that LGUP for the G3 is often distributed with the wrong DLL file. See the details here, post #11. After installing LGUP, make sure that the "model" subdirectory in the LGUP program directory is the same number as the processor in your phone, in my case c:\Program Files (x86)\LG Electronics\LGUP\model\8974 (was 8994 with the "LGUP for G3" I downloaded).
HTH
Long story short, I tried flashing an older version of the firmware because I was having constant wifi issues even with a factory reset.
Everything went well, the phone rebooted with the android character on its back with the trunk open and the progress bar loaded until it froze. Now every times I try to boot it there's the droid on its back with the frozen loading bar.
Then when trying again to flash the stock rom using the COM41 LG flash tool, it keeps saying ''communication failed with device''
Here's everything I tried:
-De-installing and re-installing the LG drivers
-Tried the LG Flash tool method with 4 different computers and I still have the communication failed with device error
-The qualcom 9008 method where you need to short the ground with another pin
-Tried using LG's own tool from their websites to try updating or use the update recovery and it still gave the communication error
I can still boot it into download mode so there is still hope right?
Which is very annoying is that I still have 175$ to pay on it and LG's ''one price repair'' costs 150$...
Thanks in advance for your advices

I've found the LGUP tool on the G5 thread and I've unlocked the hidden features. Except I keep having the communication failed issue.
Both the LGUP and LG Flash tool make the same results it gets up to 6% says: ''LAF with a few numbers LAF 567.878.XXX as example'' then gives the failed to communicate with device

Looks like I'm pretty much in the same situation . I used to have a galaxy S4, every time I thought it was dead I would find a way to bring it back to life. Even my other G3 "D851 model from T-Mobile" which I did about the same manipulations in the same goal and didn't have any issues with it.

Yes! That's the worst thing! I can set it to COM PORT 41. Then when I start the Flashing with LG Flash Tool, the phone displays COM 41 in green and the complete name of the .tot file even appears of the screen of the phone!

If you used LGUP that definitely the reason your phone is in the state it's in. If i buy a cheap g3 off of somewhere and downgrade it I'll never use LGUP. lg flash tool is your best option though I'm getting a g6, cause the g3 is old now i think you should upgrade if an upgrade is your thing the i got some good phones on my list. But if you're gonna stick with the g3 then they sell 'em for pretty cheap and if you're gonna downgrade to 4.4.2 kk then use lg flash tool. If you're gonna downgrade to 5.0 or upgrade (not really) to 6.0 then use the modified lg flash tool 2014. All i gotta say is you're phone is done i learned it the hard way

Yeah :/ it'll teach me to stop wanting to crack every phone that falls in my hands. Just to bad I still owe money on it though. I doubt selling it on auction for parts on eBay would even be worth it.
I got the same problem with my LG G3 D852. I have tried multiple USB cables and USB ports. I can get into download mode easily, factory reset just returns to the same problem with a Droid open hatch and spinning wired shape and a bar on the bottom. I have tried LG flash tool and LGUP, but both fail at 6% with a communication error. I think the problem is my USB cable, but that is just my guess. I have followed the guides on the forms on this site, that is the only conclusion I can come up with.
