I'm sorry to ask a question that may have been asked dozens of times, but I am unable to find a thread clearly describing the much talked about "Bootloop" issue with the G4. After reading through several threads, I've come to the conclusion that there may be an issue with the LG G4's with serial numbers that begin with 505.
My own G4 has been working great until this morning. I bought the device from a T-Mobile store in about June, 2015. It is not rooted, and is completely stock. This morning I woke up to find my phone would not turn on. I tried removing and replacing the battery, changing batteries, plugging it into a charger, booting without the sim and SD card.
Eventually I looked up how to boot it into recovery (power vol down, let go for one second at LG logo, then power and vol down until menu screen appears). My phone will not boot into recovery.
It starts to boot normally, but either reboots after the LG logo, reboots at the T-Mobile screen, or simply turns the screen off and stops. One time it actually booted to the home screen, but ran very sluggish, then the Lookout app reported that, "Malware has successfully been removed". Then the phone froze and I had to reboot.
From what I've read in several threads, this is a common issue and the only fix is to have LG replace the motherboard. But if this is such a common issue with this phone, why is there no sticky?
Thanks for any help or tips.

Update: LG had me send it in and they replaced the motherboard, like many others have reported. Warranty was expired by several months, but they did not charge me. Working like new.

Please help! My rooted LG Revolution won't turn on. When I unplugged it from the charger this morning I powered it off. when I went to power it back up all it does is flash the LG logo and do a little vibrate like it is force closing! I have 2 days left before I can no longer return it. I did several battery pulls also with no luck. thanks in advance!

Did you install Clockwork on it, or just rooted?
If you only rooted it, try performing a factory reset.
This can be accomplished by holding volume down and power until you see the screen change to "Clear data and factory reset?".
Press power to confirm.
You will lose your data, but your phone should return to normal.
Just rooted, no clockwork. I will give it a try! thanks!
Tried your suggestion...just keeps flashing and vibrating. Any other suggestions?
Did you ever see the factory reset screen?
No I didn't. just the LG logo flashing and the force close vibrate. the only way I can get it to stop is to take the battery out and put it back in. Then when I hold the voume down and the power button it just starts doing it all over again.

make sure you are holding it long enough. You have to continue to hold the power and vol button for sometime before you get the recovery screen.
As rooting will generally not brick a phone (it is the recovery mod that generally bricks), if you cannot get it, take it back tell them you woke up and it was on the charger like this. They should exchange it with out issue. (Do not mention that you rooted the phone)
It sounds to me like your phone is defective, it happens.
Another option is here: http://forum.xda-developers.com/showthread.php?t=1120062 .
I can walk you through it on IRC tonight if you're on around 12PM Pacific Time...
If not, there are guides for using LGNPST on the internet.
Good luck!
Thanks! Held the buttons down for a full 3 minutes and nothing. Is that long enough? Read through the other info you posted and boy does that look scary! LOL! I will try tomorrow when I have more time. Or maybe I should just return it since I have only had it for 12 days
try pulling the battery and holding the power key for about 30 seconds. my original droid use to do this from time to time and it always worked for me.
Thanks. Tried but it did not work. Ended up just returning it and getting a new one. Now I can start over! LOL Just came from the Samsung Fascinate and was pretty proficient in flashing roms and kernels. But I have to admit that I am a little confused with the process on the Revolution.
Not sure boot problem is related to root
I've had repeated problems with not being able to boot my Revolution. This has happened consistently no matter which ROM I've used. I've factory reset and tried Decrap and Revolt both. I can reboot my phone fine, but if I ever turn it off overnight, I go back to a blank screen in the morning.
It seems a number of non-root users have this problem.
https://www.youtube.com/watch?v=IOGM__SQB6Y
I'm not sure if having a low battery contributes to the problem, but I do know that Clockwork works better with a full battery.
This morning is the first time, however, that I have this exact problem. For a few times this morning I was able to get to clockwork and restore different ROMs, but always to the same blank loop during boot. Now not even able to get to Clockwork or Factory Reset. I'm headed in to Verizon to try for a replacement. I'll let you know if they make any noises about rooting.
Getting back into Clockwork
Update: I ended up getting back to Clockwork. Can't say exactly what did it, but what seemed to work was:
1. Charging the battery fully overnight
2. Removing the battery and holding the power button down for 30 seconds
3. Leaving the battery out for some time, about an hour I guess
4. With the battery still removed, plugging the phone in and allowing the bottom lights to flash about 10 times
5. Replacing the battery, holding down the power button and volume down.
After a full day of not being able to get into Clockwork, I was able to get in and do a factory reset.
Returning Rooted Phone to Verizon
FYI, I returned a rooted, stuck in boot loop phone to Verizon yesterday. In the store they arranged the return and did not ask about or look for rooting in any way.
They did try a factory reset, which was not working in any case, so no signs of Clockwork.
Same problem, different results.
I have a ROOTED LG Revo, but the first one I owned had the same problem. That one was NOT rooted, so must just be an LG thing. First phone had stock android 2.2, and this one has STOCK 2.3.4 ( after OTA ), and is just rooted with simple memory management and font tools. I WAS able to Hard Factory Reset, but the same problem still existed after reset. ADB cannot even recognize the handset. Boots with animation, stops halfway through, reboots into blank screen and freezes. RETARDED!!! This will be the second handset being sent back in as little as a month. I bought the REVO the DAY it came out, and loved it. But now I don't. No love left. I'm getting the Droid Razr!

Please don't necro threads....
Hi. To start with I bought a phone from a friend which I knew was faulty but decided to take my chances and try to fix it. He claims he did nothing to the phone but don't know for sure. Phone is in constant bootloop, Goes until splash screen and reboots. Worst yet to come - even bootloader menu restarts on constant basis when i try to get into it. Meaning it goes into bootloader but restarts in few seconds before i can get to factory reset. Computer is not picking up this device but i also don't have any drivers installed but don't even know how to install them with a phone in this state. Is there anything i can do about it? Been with Samsung for the past few years and here is everything completely different so don't know much about adb but am a quick learner and can follow any steps! I can provide picture of bootloader if it would be any helpful.

Send a picture of the bootloader while I find the drivers you need
Seems like battery is completely dead as it only reboots when there is power supply connected, but then it won't turn off (any charging light don't come on, not sure if it should though). Just now i've seen a vodafone logo for a very short second when I connected to pc from charger. But phone rebooted again just after.

edit. downloaded drivers (4.8) but that didn't change anything and windows still doesn't pick up device.
After connecting my one to computer for past 3 hours its started more frequently boot and showing Vodafone menu but still restarts shortly after. Vodafone logo shows on and lights on soft buttons starts flashing like 3 times and than it keeps rebooting. Does it mean anything?

That almost sounds like your POWER button is stuck!! Are you able to completely power off, and it stays off.
I think i know what it is. Power button stuck and keeps restarting device. Although i can feel pressing it, this is what it looks like.

Didn't see your comment but this is exactly how it looks to me. I can't switch off phone and in bootloader it acts like i was pressing power button. Although it operates normally meaning that it can be pressed down. Arranged warranty repair with HTC and they are collecting phone tomorrow.

Good luck mate, but definitely sounds like the power button is stuck
It's been fixed under warranty by HTC. They replaced motherboard on mine HTC. So all good
So. My Moto G is completely un modded, not rooted, and is exactly stock how I bought it and haven't changed any of the software. My Moto G has been getting slower in the past couple of months with everything going slower than usual. I bought my phone in February 2014.
Yesterday while I was at school, in my pocket I had my phone. I felt random vibrations in timed cycles. So I pulled out my phone and had a lol at it randomly rebooted but came back to the home screen. As I started to use it just to send a couple of messages it rebooted again but this time after the reboot animations they just went on and on, what I've found out to be called a boot loop.
So I went home did some research and figured I would have to factory reset. I couldn't get into the phone therefore I had to do it externally. I got the the menu thing ( I think it's called fast boot menu ) and I wanted to select newer bootup or power up just to see if that would possibly stop the boot loop. I selected it and got into my phone, into setting and factory erased my phone.
Well I factory erased my phone and re installed the apps I on,y essentially use or NEED such a social media, within this time there was no unusual activity. Shortly after my phone randomly rebooted ( after downloading the apps ) and turned off, and then went in to the former boot loop! I was furious!
Well here I am, left it overnight for charge and it's been looping for 10 hours. I tried going back into the fast boot menu, the first time I got into it this morning I selected recovery in hope to reset it, however the screen said no command with the android and the exclamation point. The second time I got into the menu I tried 'Factory' and it just rebooted and back into the cycle.
At one point I did get into my phone however shortly after that guess what happened, it turned off and rebooted. And back into the vicious cycle.
I am led to believe it's the power button that's causing the problem ( correct me if I am wrong ) as when I did manage to get I to the phone I did try pressing the power button to investigate this and on some occasions in did lock the phone but in several others it displayed the power off popup and then turned off shortly after indicating that I was holding the button down which I definitely wasn't doing.
So where would I go from this? Do I call Motorola, try flashing a stock ROM ( it's completely stock ATM , I don't know how to do this so if I have to do this can you please explain briefly ) or try going back into the fast boot and go into recovery and try and get rid of no command ( if I can, and how ? ).
Please any help would be very appreciated!
Thanks in advance.
PS you don't think it's the back cover that's doing it because it took that off last night '

Since your phone is completely stock, don't start tempering with it now. Just return the phone. But you have to act quick, warranty is about to expire.

Hi, I had a look online and came across a forum post saying it was a jammed or sticky power button and the poster stated to hit the power button side of the phone on a desk a couple times and it will go back to normal. I'm glad to say it did work after I hit it a couple times, as fast as ever now due to the reset!
I was wondering if I call Motorola would they give me a free new moto g out of it, as I see it as an opportunity to do so, or will they just prompt me to send it so they can repair it under warranty? Is it worth calling ?
Hey guys,
I'm on the newest 10N TMO rom. Everything's stock - no root, stable 3rd party apps, no debloat..
So I'm on the plane, playing around with the gogo inflight texting thing, which I tried with four phones and it's still never worked... My phone stopped responding and attempted to reboot - except it never finishes booting because it keeps on showing the black LG - LIFE IS GOOD screen. I attempted to master reset with the down and power button, but even after the reset, it throws me back into the loop. I've tried booting it on with or without the SD card and SIM, but it doesn't make a difference. TMO is sending out a replacement unit, but I know it's going to be a refurb. I've had the worst luck with TMO replacements since they just end up sending me someone else's broken device... The phone doesn't react to vol up + power to enter download mode either.
Any other ideas?

ok so now what i got it to go to the download place but now it is just sitting there telling me that i shouldnt un plug it. sorry if i missed the answer already.
Did I miss something here? On post 4 he states to use the power button? What? All the blogs I've read to get into Download mode states holding the Vol Up button down while plugging in the usb cable. I'm doing that and all it does is shows a battery symbol. I'm stuck in a boot loop and cannot do anything. Hoping someone has a resolution to this.
This is known issue all over the internet, has to do with some bad connector inside.
I am waiting on my replacement as we speak, my started this boot loop yesterday.
This after being rooted fine for 4 months.
Have found no way to solve, it just restarts, hangs on the animation or says its updating the apps and then just restarts yet again.
Look at your serial, the 505-509 supposed to be bad batches.
Mine is 507.

I'm already on my third LG G4 due to bootloops.
The deep freeze method seemed to work for me to get my data off.
I got a feb 2016 'buyers remorse' phone sent to me from tmobile.
Hopefully better luck with this one.

So I can't boot my phone. Previously stable h811, unlocked bootloader running latest 20i Extreme 3.3 MM with G4 Tweaksbox. I have a Qi/NFC sticker on the back, but which has worked flawlessly and was not in use when the phone died. Here's what happened and what I have attempted.
Problem began when phone simply went black. The only thing running was Maps, which had a route displayed but was not in navigation mode. The screen went dark like normal, and when I went to wake the phone, nothing happened. I was in the car and tried plugging in the car charger and did not get a charge light. Pulled the battery and was unable to get a response. The phone and battery were quite warm.
When I got home, I tried a different battery, and the screen turned on to the LG initial boot screen, but nothing else happened.
After many battery pulls and attempts to boot into recovery, I tried it with the phone plugged into the computer. Finally, it showed the charging screen and light, and after several more attempts- pulling the battery and inserting it, then powering on, it appeared to be booting, (boot animation started, but then looped and froze on the initial boot screen (with bootloader state: bootloader unlocked in the upper corner). After another round of attempt/battery pull, it booted all the way up, but at that point I had my sim pulled. Pulled the battery and tried to restart and it froze on the initial boot screen again. Haven't been able to get into recovery at all, can't get into download, can't boot past the initial LG screen. Sometimes it loops, sometimes it just hangs. Nothing I do pressing combos of buttons, plugged into computer or unplugged, seems to change anything. The very farthest I've gotten is the breathe blue light before the boot animation, but then it looped. Now it's boot looping plugged into the computer.
Any ideas? I'm at a total loss.

Im bricked myself from another issue but i think there is a black screen of death issue with some of the g4s
Try to boot download mode and re flash stock kdz with Lg up tool
You will loose all data though.
Good luck on help here noones helped me at all .
The g4 is just not a good device or user friendly
Sent from my LGMS631 using XDA Free mobile app
Black screen of death here too
Yesterday, I was using Chrome, site loading, screen just went black. I had about 1/2 battery at the time. I figured maybe the battery was just reporting wrong. When I got home, swapped batteries, same issue. I've been able to get into recovery and attempt a factory reset a couple of times (after many frustrating attempts.) The phone seems to only be able to be powered on for about 30 seconds before it goes black again. I'm going to attempt to fix with download mode now. If anyone else has solved a similar issue, any tips would be appreciated.
Hardware appears to be at fault!
Check this out, people!
http://www.androidauthority.com/lg-admits-g4-bootloop-problem-hardware-fault-669603/
Spread the word. Sounds like this is our problem. Apparently affecting mostly models with serial numbers starting 505xxxxx... which is what mine is. Called LG and they issued an RA# and shipping label to send it to them for service. I'm a little concerned since I didn't buy mine through a carrier, but this seems more like something of a soft recall than strictly a warranty issue, so I'm hoping they fix it no questions asked. I'll keep you guys posted on the progress.
Same thing happened to me today. My phone randomly shut off and it won't boot. Its stuck at the Android logo. I wasn't messing around with it. Just normal use (Snapchat, youtube). I tried booting into recovery but it just goes back to the android screen LG logo and keeps looping. I at least want to wipe the phone before I send it (personal info).
Same here. Mine has serial number starting 505, was purchased back at end of 5/2015 with not problems until this. I filled out the warranty repair form on LGs website and they sent me an RMA with label to get it fixed. I sent it in, they sent it back, and the only thing I see is on one sheet they printed out and included in the package said 'replaced board'. However, when I started up the phone it looked like new initialization with xx of yy apps initializing and then it began bootlooping with the LG splash screen. So frustrating!
So, this time I contacted t-mobile via their online chat, and did a warranty exchange through them. They will send me a replacement LG G4 next day ups air and I will send them the defective one for them to claim warranty themselves. We'll see where this goes. I might just take the replacement unit and do a tmobile jump exchange to another device. I wanted to wait for the new line of HTC nexus phones that are rumored for this year (and was loving the LG 4 until it died), but I might need to just jump twice this year and go for something like the new Samsung S7 of new LG G5 now and then again switch to HTC nexus once that comes out.
Sent mine to LG, and they fixed under warranty with no questions asked. Got it back within a week. All good now.
