This is embarrassing, but I was trying to install Pokemon Go on my G4 and the phone got really hot and rebooted. It never came back. Just went into a boot loop. I found instructions online on how to do a master reset with the power button and volume down letting it up briefly when seeing the logo and then pressing it again and letting it boot. I answered the question about deleting all user data and then answered it again. It said it was erasing data, then froze for a few hours at "optimizing apps" on one of the steps while I left it plugged in. I eventually pulled the battery to get it to respond again and now it just shows the LG logo and then goes dark. While dark it doesn't respond to button presses or let me try again to power it on, etc.
Any chance of me getting this phone working again? Is there anything else I can try aside from the master reset that I've already tried?
Hello if you look under the battery and your serial number starts with 505 or close its dead.

send it back for reapir.
hi, mine was 509. It died 2 weeks ago, showing only "LG life is good" if trying to boot it. No way into recovery. (did boot one time very slowly to lockscreen before the definitive death)
This seems to be the same for you.... dead CPU I suppose. I'm still waiting for the repair.
(curious about the 505 asserted here, since mine was higher)
Hello the first 3 digits of serial number indicate date of manufacture, and the early ones have a manufacturing defect.

Hello,
mine was 510 and died on me 4 weeks ago, (boot loop with only LG logo) as it died from overheating (or at least was very hot when die occured), I tried to cool it and it was "succesful"
It put it in the freezer for some time and then could boot it on TWRP and make a full backup (I left it in the freezer the whole time)!
boot at normal temp lead to black screen in 10-15secs. I sent it back for repair (motherboard replacement was made in less than 1 week by Lg France), I am now waiting the answer from Lg developer to unlock the bootloader again.
I guess you can at least try and see if you can have the same result as me.

Dear xda-developers,
about a month ago my phone started acting funny, sometimes my browser or youtube would close randomly.. well, if it happend i just thought “oh, i pressed home accidentaly” or “oh its just a bad coded app”..
just 15 or 20 days later, not only my browser or youtube were crashing down.. it took my launcher with it (resulting in htc-sense prompting LOADING... for 2 minutes).
well, so far it has been “just annoying” me but my phone remained "functional" but: update saved the day and fixed this problem :laugh:
untill yesterday: all apps started crashing (including PROCESS ANDROID.PHONE etc.), a reboot fixed the problem.
today, all apps crashed again.. reboot didnt fix it, and my phone got stuck on boot sometimes (sometimes on the "ONE X" rom screen, other times on the "HTC" screen).
so, what did i do? what everyone would.
i started my htc bootloader, clicked "factory reset" and i hoped that this would fix my problems
it booted, and rebooted, and rebooted, (bootloop for 3 times), and then finally: it booted normally..
all apps crash again!
this happens every time i start it.
now it doesnt even boot anymore (stuck on htc logo), so what do you guys think?
faulty ram? warranty ?
edit: now my screen stays black, phone doesnt respond to anything.
Dunno, it's a strange one. Drop into fastboot and run:
fastboot getvar version-main
Then look on htcruu.com for a matching RUU, this is the ENDEAVORU.

cant get into bootloader, phone died.
it has been charged this morning so its not an empty battery.
i did NOT root, flash or unlock my phone.. i've only updated through "settings" in my htc.
(want to use it for a year before unlocking.. because warranty will be voided)
Try plugging in a mains charger, does the charge light come on within a few minutes?
Now plug into laptop USB, charge light? Anything in device manager?

This is so weird, charger LED will not turn on when connected to the charger.
i tried connecting it to my pc, same problem: but with an error:
"usb device not recognized" (yellow warning triangle near the error)
its completely dead, not responding to anything or any input.
before it died, i did try 3 factory resets with a full battery (and i didnt touch it)...
none of these factory resets fixed my problems.. :/ well atleast htc cant say "try factory reset" .
since the bootloader is bricked, the phone isnt even responding to charger and it wont "try" to turn on..
i think my phone is completely dead.. just have to send it back to htc (during christmas..! will take longer than
normal i guess).
the weird thing is, i havent done anything wrong to my phone.. havent flashed, havent updated the bootloader, havent rooted it or even installed another recovery or rom. (i've only dropped it once, the screen broke immediatly.. got it fixed by my phone-insurance company thats certified)
any other solutions? would htc let me pass the warranty and repair it for free? (its just 3 months old)
Dude that's one of the best and funniest starts to a post lol
'Dear xda developers'
In serious response though. HTC warranty is two years should be fine. They will ask for proof of purchase. If you havent got it they might still do it. Failing that and they don't. My normal advice is mail your regions ceo and complain then they'll do it most probably

Hello,
Today, while I was using my phone, it restarted itself and has been stuck at a boot loop almost entirely since then. It has successfully booted up 2-3 times but will usually restart itself within 30-45 seconds of booting and then will be stuck in a boot loop again. When it has started up its usually after it has been bootlooping for a while. I have an H811 , I'm rooted and using xTreme Rom v2.0. I have had occasional random reboots here and there before but the phone always booted right up again without any issues. I haven't done anything with root/recovery since early September.
I've tried doing a factory hard reset without any luck. My phone booted up after I tried the hard reset and it was like the reset didn't happen. I can't boot into TWRP. I can boot into download mode and I tried to reset using kdz. It got to 100% but the the phone restarts and is back in the boot loop (then the lg flash tool gets an error and force quits). I've tried removing my sd and sim cards, I've tried swapping to a different battery, I've tried leaving the battyer out and letting the phone cool down. Nothing is working. I have noticed that when the phone is going to boot up correctly the full LG animation plays. When the phone is going to boot loop I only get a static LG Powered by android image.
Since I tried and failed to reset to stock using kdz, the phone no longer boots up past the LG screen. I've redownloaded the kdz file and tried to reset again with the same results. When I have it in download mode Windows recognizes the phone but it says there's an issue with the MTP driver. I've reinstalled the drivers and I still get that the MTP function isn't working correctly.
Any suggestions?
Hey man u r just having my problem. There is a thread already for this http://forum.xda-developers.com/showthread.php?t=3233160
Did u do CSE flash? If not, try to connect via adb.

I am having the same issue. I have T-Mobile G4 that is NOT rooted. I bought it on release day. I too would get random reboots, particularly after the recent security update. I also noticed that the operating temperature was really high, a lot lately. I thought it was a rogue app (clean master). Anyway, I updated a few apps and installed a few watch faces. Suddenly, my phone was drained prematurely. Plugged it into a quick charge charger when all the fun begins. Early on it would boot to the home screen but would reboot a minute or two later. Then it stopped booting to home. On two occasions that I caught, it was starting up like a firmware update just installed with the "Android is starting 1 of 143 apps" type of line. After seeing that and still not getting to home, I figured I might as well factory reset it. Well I was amazed to discover that a factory reset yields the same boot loop. All I get is the LG logo.
Defeated. I go to my local TMo retailer where I bought the phone only to find out that I have to wait for delivery of a replacement. I'm in Jump btw. I did notice that when the phone will boot to home screen for whatever length of time, the LED would work. The LED does not work during a boot loop. My research on this issue uncovered an alarming trend on the Internet. No solution other than replacement. No cause has been identified either. Without proof, these are my top suspicions: Quick charge, 128G SD, apps moved to SD. My hunch is quick charge. All of my chargers are Qualcomm certified quick chargers. and I use them 95% of the time. I would hate to add LG to my list of boycotted Android vendors under Samsung.

Thanks. I'll try reposting this there. I did use CSE flash. Oddly enough it booted up once this morning for about a minute then got stuck and rebooted. Now its back in the boot loop.

Sounds like the boot loop issue is a decent sized one- quite a few others, from different variants, having all having a similar issue. For me I was walking with my phone checking facebook when it restarted and got stuck. I definitely notice the LED issue too. I'm not on jump but will likely go into T-Mobile today and see what they tell me.

Exactly what happened to me. now after CSE flash of KDZ, it won't start at all. just boot looping. also after hard reset.
Hi All,
My phone will not boot. I have tried soft resets multiple times. It will not even boot after I selected the factory data reset by holding down the volume down and power button since it seems like that requires a full boot to reset. During boot it shows the LG logo and sometimes makes it to the AT&T logo but after that either black screens, back to the LG logo and powers off, or boot cycles and keeps showing the LG logo multiple times. I have taken out the SD card and tried all these steps with and without it. Took out the sim card and reseated it. The phone is stock and not rooted.
Let me know if you guys need more information or have any ideas.
Thank you all and I'm sure this is been solved before, but I'm at work and don't have time to research so thoroughly through all the threads/posts.
if it's not rooted and stock, i'd send it back to lg under warranty

I have already put in a ticket to LG before this post for their return shipping information and repair. I was just hoping by some miracle that someone had a fix besides a factory reset since it won't even boot to allow the factory reset.
Thank you
Ok, sorry for the lacking help! Good luck, hope someone else replies with a suggestion
This just happened to me too.
Shows the lg logo. Sometimes the att logo.
But, just doesnt boot up. All i see is a blank screen :/
From everything i read here on XDA it seems that many of the phones are faulty.
Symptoms are almost identical. Outta no reason reboots and dead phones. Many of them are stock not rooted.
I have still no answer from LG about mine. Hope to hear soon. Something is going on with these phones but what causes it.....that`s the question....
The same thing happened to my H-815 model. I went to bed listening to YouTube and woke up to a dead phone. The LED doesn't come on when charging. Just like you, when I turn it on all I see is the LG boot screen and then it shuts off. The phone repeats this twice and then doesn't turn on again.
So I'm pretty sure my phone is fried. Just wanted to double check with anyone before sending it in.
I was driving and streaming music to my car when it stopped, and I noticed my screen wasn't responding. Swapping the battery only showed me the LG splash screen before restarting, showing the splash screen, then shutting the screen off and not responding. No length of time will let it boot.
I have everything on my SD card so no worries, I tried wiping from recovery. TWRP booted, froze, screen shut off and the phone was again, unresponsive.
Last resort, restoring with the KDZ. I got it into download mode, waited to see if the screen shut off again, and went ahead with flashing after I saw it was ok. It finished up and rebooted, and once again all I saw was the LG splash screen. I got to the "Android is upgrading" screen at one point, and it froze and shut off the screen again. It was, again, unresponsive.
tl;dr
Phone crashes, even after KDZ flash and master reset. Is there any hope I can fix it? I have a backup phone in the meantime but it's so horrible, I miss my G4!
Thanks for reading.
Better send it. Got crazy bootloops myself.
At the end even couldn't charge it. After i got it back i asked what was broken, they told me that it was unable to repair mainboard and usb port and they put new.So my advice let it fly to the repair shop.
Hey. So just yesterday I flashed Venom's kernel (could be completely unrelated to the issue). However today my phone froze up and when I tried to reboot it all it does is vibrate. The screens stays off completely and all it does it vibrate once every minute or so. I tried the guide to unbrick it and restoring it with xFSTK but it's basically impossible since it keeps rebooting and it is only detected for a couple of seconds before it disconnects again. I managed to get it to install dnx,fwr droidboot and ifwi. But when xFSTK tries to start it up nothing happens and it times out. Hopefully someone can help me here. Never seen anything like this before
I think I saw somewhere a similar thread. Their solution was to let the battery completely drain before starting it back up. Maybe it will help?

I tried opening up the phone and remove the battery. Then left it detached for a while, then reattached it. Since making it run out of battery could take days. I will still try that however. But detaching it and reattaching it did nothing unfortunately. Went right back to vibrating every minute or so with just a black screen
