Some kind of "bootloop" on my G4 - G4 Q&A, Help & Troubleshooting

Hello everyone,
I'm trying a new telephone, gave on loan by a friend. So I left my G4 in the drawer for a month, and it's battery dropped to 0%. Today I tried to turn on the G4, the display showed me that the battery was full out.
But, when I plug in the charger, the telephone reboots, does the animation of LG booting and then stuck on the LG Life's Good logo, and the notification led keeps flashing blue as the common booting. I saw that the bootloop repeatedly reboots the phone before the animation , pratically when there's "Android" in the bottom part of the screen. My G4 stucks after this, so I hope that it's a sort of bug or something similar.
Any suggestion? Someone else have got this problem?

It is either the ilapo bootloop issue,Or it is a faulty battery. the LG G3 was reported of doing the same thing.
But hardware issues are a common problem on LG G4
You can attempt a warranty claim through lg possibly if hardware.

Try charging your battery externally using a desktop charger
if your phone boots it was probably a battery problem
if still stuck on logo then its either soft brick or ilapo
try all the soft brick fixes (like lgup and flashing twrp) and pray. if they work, that's good luck
if they don't that's probably ilapo
now u can try this

[Q] Lockscreen On / Off while QI charging.

Hi
Yesterday I've got the OTA to 20E for my D855.
Now I have a annoying problem.
Last night i left my G3 on the Original LG QI Charger (which i'm using since i've got my G3.
In the middle of the night i observed a strange behavior.
The G3 turns on displaying the Lockscreen... after about 5-10seconds the screen turns off... then it takes about 30-60 seconds the procedure starts over...
So the screen goes on .. off .. on .. off .. and so on.
The same behavior happens on another QI Charger.
Without the charger this behavior stopps.
I think this bevavior starts when the battery is full.
Has anyone else seen this behavoir or has a solution to turn this off?

Yeah cause the QI power is low so it start charging for 10'' then stops,the screen is on,then start,the screen goes off,then stop...etc etc etc!!
But before 20E (Android 5.0 I didn't have this behavior).
So there must be something wrong.
I am getting this as well, same charger as before android 5.0 update
It's an annoying bug that's been in all the G3 lollipop builds so far, I posted about it a while back: http://forum.xda-developers.com/lg-g3/help/lollipop-v20a-wireless-charging-textra-t2935987
I've been pestering LG UK via twitter to fix it, maybe if more of us contact LG in our countries it will get fixed?
@PsychoMania Thank you for your feedback. Since this issue is widly spread I've sent LG a message on the LG Service Page for Switzerland.
I'm curious to see if and when they will answer...

Help! Blue screen, no download mode, can't factory reset.

Hello!
A few months back I rooted my Verizon LG G3 without any issue. Worked great, went smoothly.
Last night I was watching Netflix when the phone suddenly shut off without warning. I haven't recently installed anything out of the ordinary. When I tried to reboot, I got the green screen with a HW reset warning. Pressing Vol down to reboot gave me a blue screen. I'm able to reboot using Power + Vol down, but if I try any of the options [including factory reset] it suddenly goes to the blue screen.
I also tried getting into download mode without any luck - you guessed it: Blue screen. If I connect the phone to a PC, it doesn't recognize it. I've tried downloading and running the LG PC Suite, but it can't connect to the phone.
Any thoughts on what's going on and how I might be able to repair it? I've looked through various threads here and anything similar seems to revolve around flashing gone awry...and I'm not flashing anything (nor do I really have the know-how to do so).
Thanks, in advance, for any assistance.

Do you get the blue screen when attempting both recovery and download mode?
Blue screen no matter what I do - recovery, download or normal mode. As a matter of fact, now the phone won't attempt to boot at all.
Really strange.

I feel you. I started a thread about my issue but sadly no one helped...
Seems like you got a "bricked" phone though Qualcomm phones are theoretically unbrickable.
I was in a worse situation than you, I think my board fried haha, but i'll try my best to help you here
Do you have a custom recovery?
IS there anything else showing on the blue screen? (example: Factory Reset Status)
also does your led flashes?
If you can't boot, or flash through download mode (KDZ and TOT method) I think either your bootloader got messed up (for no apparent reasons apparently) or it's simply a physical defect.
Are you sure your PC doesn't detect your phone's USB after installing the appropriate drivers?
Or does it detect the a device as "QDLoader 9008"?

I appreciate your help - thank you. For what it's worth, no - there was never any text on my blue screen, and I couldn't ever get it to get into Download Mode. Plugging it in to a computer did nothing except give me a blue screen, and the computer never recognized it as a device.
I ended up getting a replacement G3, so [for now] my troubles are over. Thanks, again, for your help.
(I guess this thread can be closed now.)

Quick update: I just learned today that a co-worker who also has a G3 (T-Mobile) also got a blue screen last week. He was told that this was a "known issue" with this phone...but they wouldn't provide him with a replacement, which also seemed strange.

Glad you got it replaced!!
And a shame for your friend :/
In my case, it was practically hopeless, nothing seemed to work, eventually i had to have the motherboard replaced. It was clearly a damaged bootloader, yet, they repaired it under warranty! funny
I doubt you can damage a bootloader without root or stuff.
I wonder what would suddenly mess with the bootloader after months of no issues?
I'm having the same issue. Or rather I had the same issue but I was able to get it back to stock through all the various .tot methods and using download mode and everything. I had no issues so I rooted it again, installed the 35B firmware from xdabbeb, as well as his 46A so everything is still stock, and running the latest android update, but the phone is still rooted. In any case it has been working fine for almost a week. Today it shut itself off again and now only blue screen when I turn it on. It barely gets past the LG logo before it blue screens again. I can't enter download mode because while installing the device on the PC it blue screens and crashes in download mode.
So I'm not sure what the deal is. I have the extended insurance and warranty but if you pull the battery for a couple hours and put it back in it will boot past the LG screen and start the OS, but the boot loading screen shows "Android" instead of "Verizon" so they'll know it's a custom firmware and do nothing for me. If anyone has any ideas I'm open to them! I would love to revert back to stock but with it crashing in download mode I can't even do that.
try these things but g3 is crap phone
you can try these things: use stock charger and try to boot then, i think its a 2amp charger. if it boots then swapping out battery with good one will likely cure it. its hard to find good new oem batteries though. usually that only works if you see a blue screen with a number on it. if its just a flat blue screen and connected to stock charger wont improve anything then its likely corrupted bootloader (hard brick). i currently am trying to resurrect one that is acting the same, it will only randomly turn on to blue screen, sometimes after days left with battery in while turned off. all the tricks like taking battery out, connecting to charger or computer without battery or holding power button to drain capacitors with batt out dont seem to help really. i am trying to get it to turn on into download mode at which point i will flash stock kitkat but seems like it wont happen. seems like lollipop 5.0 has something to do with this issue. there is an outfit on ebay that fixes it for 29bucks in texas. you will find them on youtube. g3 is crap. g2 was excellent except for touch screen issues.
can you explain what outfit in you are talking about? i am facing the same problem,

Sorry "outfit on ebay" means seller on ebay. Don't remember what their name was. With the g3 it's like this: bootloop is usually fixable with a new battery. If it loads with charger connected, then definitely try new battery. If blue screen without a number, it's likely faulty motherboard. It may still boot occasionally, after leaving batt out or putting in freezer (yes freezer). If it does boot then do a backup immediately but phone is likely in need of new motherboard.

BSOD is not so BSOD as you might think. This is actually the default view of the screen controller. It just means.... well... basicly... you're ****ed....
Something in the hardware doesn't fire up as it should and it's usually the SoC.... or the so called processor. Heating and baking might help if the problem is with low temperature welding but again it might not. And even if it does... it will be totally temporary (most cases weeks) because of the rapid increase/decrease of the processor temperature and thus welding joints... I'm basically in the same situation right now with the same phone... he fought well as it is 2014 phone after all but in the end it died heroically.... ;(

LG G4 bricked?

Good Morning all....
Yesterday I took my phone off the charger, played some of my games I play and then took a nap....battery percentage was probably still around 80% at this time...when I woke up, the phone was off. I plugged it into a charger and when the battery displayed it said it was 1%. I let it charge to about 30% and tried to turn it on. All I got was a bootloop of the LG symbol in the beginning. After that I tried to use recovery mode to clear the cache and it still just jumped back to bootlooping. I then tried factory reset from recovery mode and it just sits stuck on the yes or no screen to do the reset. I then tried to flash the firmware using the LG tool on my computer and it starts to flash then says it has lost communication with the phone, and to try again later.
Any ideas? Totally Stock LG G4 with the latest update.... I love my phone and hope theres a fix for this.
sounds like you got the dreaded bootloop issue... this is a known hardware defect that occurs (randomly it seems) and renders the phone useless. There are a few solutions if you hunt (freezer, or removing the motherboard and baking it in the oven [precisely]) but your best bet is to go to verizon and get a new one warrantied (no promises it won't happen again) or mail it back to LG for them to repair, sadly.
nice phone, until it isn't..

Phone wont boot due to motherboard?

Hello!
So lately i tried to change battery on my LG Optimus G E975 and i faced some problems during that process... Now the battery connector has fallen off and phone cant boot properly and only dies after the lg logo shows up. I am able to boot into download mode for a period of time and then it dies again... I have pictures off the motherboard aswell as the battery connector, have a look at them and please tell me what i might be able to do to make the phone alive again
Thanks in advance.

HELP? BLOD or Power Failure?

My phone is unresponsive until i plug it in the charger and the red led starts blinking...after a bit the phone seems to charge and if i try to boot it boots normally until it reaches the google logo and becomes unresponsive again...After the first attempt to boot the phone always is dead until i leave it for an hour out off charge...What does that mean,is it the bootloop of death or a battery failure... After that i'm thinking about switching the phone but it would be nice if i could fix it at a low cost (btw my warranty isn't valid because i unlocked the bootloader)
(Kindly sorry if i placed the thread at the wrong category!)
