[G4 Q&A, Help & Troubleshooting] navendugoyal:
Same problem I have run into :(

Hi Guys I have the SEA variant H815 model.

This is my sequence of events.

1. First thing I did was to root on an unlocked bootloader as bootloader unlock wasn't available at that time.

2. Then after the release of marshmallow I flashed it using flashfire - as there was a version available at G4 android development, which could be flashed without unlocked bootloader.

3. Then I realized the bootloader unlock was available for the SEA variant so went ahead and did the official LG unlock of the bootloader.

4. With an unlocked bootloader and android 6.0 i tow I wanted to get the root again which I had lost after flashing the marshmallow.

5. So I tried flashing TWRP for a custom recovery and to get root through it. TWRP install always failed using fastboot (fastboot flash recovery command).

some luck with TWRP when i used fastboot boot twrp after copying twrp in the internal storage.

That is when the problem started. I clicked reboot system in TWRP and all hell broke loose. I am stuck on LG bootanimation logo since then.

I have tried all possible methods described here and possibly everywhere else.

Looking forward to a solution as many others.

Does anyone know how to detect my device is susceptible to motherboard problem before the problem happens?? I have been following the Sprint forum. People there saying that devices made before September are risk-prone. But most of the devices I guess made before that. So how to tell?
[G4 Q&A, Help & Troubleshooting] TheBledard:
I'm currently flashing mine, I report you back, if it works, we'll find how we can manage to flash yours.

Well, odd note:

In the Octopus software, Android version is 5.1 and build is V10d. In the Download Mode, in the little box, SW version is 20A and Android version is 6.0. Why so ? Maybe that's why we can't currently use Flashtool and LG Update to get our device back, along with the issues with the DLL file...

[G4 Q&A, Help & Troubleshooting] TheBledard:

Did you solve your issue yet ?

if you can log to recovery and download mode you can fix it congrats ;)

waiting for your answer to explain the steps so i dont type them for nothing lol :)

just fixed my lg g4 h815p yesterday took me around 8 hrs it was having the same problem
[G4 Q&A, Help & Troubleshooting] shudoha:
how?
[G4 Q&A, Help & Troubleshooting] navendugoyal:

[G4 Q&A, Help & Troubleshooting] Waleedaligomaa:
Well first of all i tried fixing it on windows 10 but it never succeeded for like 6 hrs so i had to install windows 7 ultimate and got my phone alive in like 2.5 hrs so all what i am going to discuss if for windows 7 users because it looks obvious that windows 10 lg drivers aren't ready completely yet i will tell the steps that i followed but cant tell if all of them are important

1- Boot to recovery mode and get your phone wiped (assuming you can boot to recovery)

2-download the .kdz compatible for your phone from here http://storagecow.eu/index.php?dir=Xda/LG+G4/ thanks to [MENTION=2607037]hyelton[/MENTION]

3- download and install flash tool and drivers from here http://oceanhost.eu/ed0bnrnghgef/LGUnitedMobileDriver_S51MAN312AP22_ML_WHQL_Ver_3.12.3.exe.htm

http://oceanhost.eu/mipqojfvv9ti/LG_Flash_Tool_2014.zip.html thanks for [MENTION=2607037]hyelton[/MENTION] again!

4- Boot into download mode (assuming that you can do that)

5- MOST IMPORTANT STEP FOR ME get to device manager on your computer and scan for hardware changes and make sure your internet is working properly its very important that your computer defines the drivers for your phone correctly (windows 7 does that easily through searching for drivers on internet while windows 10 failed to do so )

6-Now open the flash tool and locate your .kdz file then use cse flash ( thats the one working for me) make sure that the type is CDMA and phone mode DIAG now just click cse mode >> start>> change the language if you would like to and press OK then you get your device flashing and you can see progres on its screen

thats the steps exactly that worked for me if u faced any trouble during flashtool its always a problem with drivers make sure that drivers are corrective defined

GOOD LUCK

Hit thanks if it helped and PM me if u faced some trouble i will be glad to help

[G4 Q&A, Help & Troubleshooting] pen²:
Translated steps from http://www.android-hilfe.de/thema/a...asht-und-wieder-zurueck-auf-android-5.733674/

Downgrade to LP was possible if you flash using "Refurbish".

"Refurbish" is essentially the CSE Flash (i.e. you lose all data).

"Upgrade" is the normal flash of other flash tools (i.e. data is kept).

Manual for the tool:

* Install both files

* Boot device into download mode (shut down device, press volume up, connect with PC)

* Tool starts ONLY if it recognizes a connected device.

Now it is getting important: You can only choose kdz files for the refurbish mode using the following workaround. Otherwise, you can only flash tot files:

1. Choose "Upgrade"

2. Click in the line with "bin" and choose your kdz using the button with the three dots

3. Close the program using "exit"

4. Start the program again

5. The program always starts with "recovery" but it still remembers the kdz file from step 2

6. click "start"

7. after about 5 minutes of waiting, the flash is through

Disclaimer: I couldn't try the steps or the tool myself, so I "blindly" translated it. Most of it is clear, however, I miss the point where "refurbish" mode was used.

Is there anyone else suffering from this?

H815, rooted, twrp, running stable with seven's LP build. Suddenly it freezes while browsing and reboots.

And reboots maybe ten seconds after each boot. Occasionally, it would reach the pin lock, I enter the code, apps start, reboot (everytime at different stages).

TWRP seems stable (no reboots).

Reflashed the rom, still reboots.

Formatted system, internal storage, cache, reflashed the same rom, still reboots.

What would you suggest as next steps? Flash a KDZ if possible?

TWRP flash the stock v20a system, kernel, modem

Reboot into recovery again

TWRP flash V20a bootloader

Reboot into system

Set up phone

Then I was able to use LGUP to flash my v10e KDZ with the refurbish function.

Boot Loop

Hi all. My G4 H815 was manufactured in June 2015. Mine was purchased on 24 July 2015. started to boot loop on 19 November 2015. Returned it to LG the next morning and just got my motherboard replaced and received a November 2015 unit today. The technician does not know the problem of the unit when asked.
[G4 Q&A, Help & Troubleshooting] Nadeox1:
Thank you a lot mate (and that dude on the german forum). This saved my phone.

I accidentally rooted with Marshmallow, and went stuck in a weird bootloop.
[G4 Q&A, Help & Troubleshooting] Ali Mirza:
Worried if it can be repaired under in-box warranty

My H815T (hong kong version) being purchased from a grey market in Dubai, there's in-box warranty in original box, i'm worried that LG only repairs H818 variant only , I'm having annoying boot loop and checked my IMEI that my phone is 6 months old prior to manufacture date. Should I send my G4 to LG Hong Kong to replace motherboard for free? Hate to see the situation of G4 like this!

And inside the original box, does all G4s carry international warranty?
[G4 Q&A, Help & Troubleshooting] montrealguy:
I also have a H815T and am in a bootloop at the LG logo. As other people said - sometimes it starts very slowly and open up to the homescreen, but then the phone just shuts off and starts the bootloop again.

I'm running the LGUP Marshmallow for the H815. It was working perfectly until this morning. I'm wondering whether a faulty app was to blame.

I tried upgrading the kdz bin again through LGUP and it completes but it still goes into bootloop.

Is my phone recoverable or does it need hardware repair?

At last.....at last... what I started, paid off or should I say, what I dreamt, came true. I have been creating posts, threads, polls etc. so that well known websites likes androidauthority, pocketnow etc. would write about the bootloop issue in their websites so that this becomes public n LG acknowledges it. At last they did it authough previously many people discouraged me n were annoyed at me.... But I took all the initiatives that I could. Now u see how many people are suffering. I wish these websites would at least gimme a little response when I requested them, so that not so many customers had to suffer. Anyway here's the link: http://www.androidauthority.com/lg-g4-bootloop-petition-669421/

RIP my G4. Was working fine, then all of a sudden it reboots and freeze on LG logo. I try to fix this and it boots normally.

Then almost an hour later, it reboots continuously.. tried my best but still bootloop. I'm going to download and flash kdz.. if it's not working I'll be obliged to go to reseller and ask for a brand new.

Not lucky at all. As said in previous posts, impossible to reach adb and TWRP (stuck 10 seconds on factory reset then back to bootloop) :(

P.S. bough my phone on August, no problem since then except today :(

Heya, my G4 has some issues too...light usage, everything is ok, it just freezes most of the times when I receive phone calls, it hangs and vibrates until it reboots, then all is ok until it happens again. I can leave the phone sitting all day idle and nothing happens, something is triggering this. to isolate the problem, I tried to measure the battery with a multimeter, and the voltage fluctuates between 4.03v and 3.5, it stays at 3.8, then at 4.03, then starts to jump around, the lowest was 3.5v. my S/N starts with 509, model H815. is this a battery related issue? is it normal for the voltage to fluctuate like that? haven't got a second battery to swap yet.
[Samsung Gear S] smatofu:
Hi,

The tread is so other people don't make the same mistake and they don't have high expectations. I was able to connect Gear S to Sony Xperia (the usual: some features worked, some didn't). One of the main purposes of buying this watch was running outdoors. I think there is no way to use S Health with a non-Samsung phone. Nike+ works. However Nike+ was designed/coded by a complete idiot. I am extremely frustrated. There is a big white distance number. Other metrics (time, pace, time of day) are displayed with a small black scrolling font on a red background. The scroll is pretty fast. It is impossible for any normal human being to read those scrolling numbers, especially while running: they are too small, scroll too fast, the contrast is too little.

The design is as if they want to discourage people from using the app! Or maybe it was designed by someone who never run?! I am returning the watch!

BTW, you can find "revelations" on the Internet about reverting Gear S colors in order to use Nike+. Doing it breaks other watch functions and doesn't help much. Why would we have to go through so much hassle for the very basic feature: seeing running time in a running app?!?!?!?!

S.
[Samsung Gear S] contradude:
Why not use S health?
[Samsung Gear S] foxbat121:
Because he doesn't have a Samsung phone.
[Samsung Gear S] rsfinsrq:
I believe the 9/17/15 S Health update added support for non-Samsung Android devices. It's available in Google Play.
[Samsung Gear S] ampm325:
And he didn't even complain about how inaccurate the GPS is. I shaved a minute of my mile time switching back to the Nike app on my phone.
[Samsung Gear S] hackerse7en:
simplest solution, install android on the watch and download any running app youd like, like endomodo or so, or download nike app for android ahahahha
[Samsung Gear S] smatofu:
Thanks for replying. I have returned the Gear S watch. Samsung did everything it could to discourage me from using it with non-samsung phones. No problem! Fortunately, there is something called: competition. I am thinking about buying LG Urbane 2 LTE. It will be available in a week or two. If not Urbane, the progress is fast and there will be more wireless/phone watches soon.

S.
[Samsung Gear S] foxbat121:
I'm also interested in the LG Urban 2 LTE but need to see more details first. I have absolutely zero interest in another Samsung phone. They are pure crap. My current phone, Galaxy Alpha, not even one year old can't get a decent reception anywhere. The only reason I haven't jump on Nexus 5X or 6P is because of my Gear S.
[Samsung Gear S] AnotherLameUser:
So you but a low end device and then complain about a low end experience? Try a note 4 or 5 or s5 or s6. All of them are impressive devices.
[Samsung Gear S] foxbat121:
First of all, Galaxy Alpha is not a low end device. Don't confuse it with A3/5. Not the same thing. I have owned Galaxy S, S2, S3. All premium devices at their time. And they are all craps (original S has crappy, barely working GPS, a well known/documented problem, S2 is a so so device. S3 battery circuit craps out a few days past 1-year warranty). Have no interest in Note 4/5 or S 5/6. Handled them and they are not that impressive.
[Samsung Gear S] AnotherLameUser:
Why would you continue to buy samsung devices if all of them are "crap" as you put it? Do you always buy products you hate and then continue to do so as a form of self punishment?
[Samsung Gear S] foxbat121:
It is none of your business what devices I buy. But I thought I need to speak flankly about Samsung products since I probably owned more Samsung products than most.
