Icant beleive how lg does quality control. It is probably such a pain in the ass for LG in terms of customer satisfaction.
[G4 General] thorcyar:
I am surprised, but it SEEMS that the factory reset did actually correct my freezes issue (not seen yet, as opposed to already present at setup screens when I got the phone back). so they did corrupt the system in their factory and did not test their repair .... wow, how professional is that :confused:
[G4 General] linasj:
I don't really have the time to go through the whole thread, but what is there to avoid doing in order to avoid bootloop issues? I'm asking, because I just checked my serial number, which starts with 505. I thought maybe there's something I can do to avoid the issue. So far been using the device for a little over a year, no issues whatsoever. I'm not rooted, so no customs ROMs or recoveries have been ever installed.
[G4 General] thorcyar:
nothing you can do. It's a matter of elements not beeing correctly sticking together in the phone, probably bad soldering.
[G4 General] linasj:
So things like rooting, installing custom ROMs, recoveries, kernels and such have absolutely no impact on whether my phone could eventually get into a bootloop? As in, it's just bound to happen at some point no matter what?
[G4 General] Jens1969:
All that does not seem to be related. Not unlocking your phone could make a huge difference for your warranty claim. But even many devices with unlocked bootloader got repaired for free. One thing that you can do, is make backups regularly. ;)
[G4 General] chriss_android:
They probably sold this device in the millions but not so many complaints i read in the forums... i also had this lockup/bootloop issue just a week after the last Firmware update was issued. My phone was bought in June 2015 and is one of the 505 serial-numbers. LG repaired it (switched MB) without any issues and they even added a complete new display unit because my front glass was getting loose again, probably glue was melting or something like that. It was a rough ride with the LG G4 so far, because even 1 week after i bought it, the display was already replaced under warranty, because there was an issue with the Gorilla Glas' top layer getting off or so...

Hopefully it will now run smooth as before. And yes i also noticed from the beginning that it wasnt as fluid as my older Samsung Galaxy S4, especially when drawing through menues or even worse when typing in any app - it seems my samsung could handle more simultaniously inputs (im a fast typer on smartphones). Probably wont buy an LG again and will stick with the Samsung Flagship Models. Loved everyone since the S2 Series.
[G4 General] Diatomix98:
Hey bro, I'm a Malaysian as well. Went through so much troubles to eventually get an Euro version after the SEA variant. It's so good to have its bootloader unlocked with useful mods.

http://www.handtec.co.uk/lg-g4-32gb-smartphone-genuine-leather-black.html

This is the site where I bought from. Hope it helps, good luck.
[G4 General] Spillunke:
NOT! LG didnt repair my phone, because of the unlocked bootloader. They wont repair if the phone is software-modded. Interesting, because its a hardware problem. FU LG, will be my last LG device.
[G4 General] dontpannic:
That is the most ridiculous thing I've seen all year. I've got two eyes, and both of them are shortsighted - therefore if my maths is correct 100% of eyes are short sighted.

It just doesn't work like that. You have been unlucky.

But then others have had warranty repairs done with an unlocked bootloader too. This is a local LG service issue.
[G4 General] Spillunke:
Ok, then FU LG Germany! ;D
[G4 General] Sammae7:
Topic creator is making a very bold, but probably true, statement.

I'm sure use of the device plays a very large role on when it'll happen. I'm a moderate to heavy user and mine hit after about 8/9 months.
[G4 General] daddymikey1975:
Mine died last week. Purchased in June of last year. Sprint model of that matters. I'll be done with LG after this fiasco.
[G4 General] nipun1110:
Ok tell me one thing, any defect in hardware other than drop or fire or water damage is to be repaired by the manufacturer under warranty if warranty papers are available, isn't it? There was none who claimed that LG didn't repair his device even though he had warrenty. Problem was for those who bought it from third party sellers without warranty and LG wasn't or I should say, isn't repairing those. Imo petition was that LG allows these devices also to be repaired under warranty as this was/is clearly a manufacturing fault. Otherwise why there would be any petition???

Then you asked why I bought both 505s. It's because I couldn't take risk 2nd or 3rd time to buy a G4 without warranty and only G4s available here in my country from the local LG are all H815-SEA with S/N 505s. So.......

Then if LG are the only vendor who doesn't support bootloader unlocking. Technically, no but practically yes. I have seen only G4 has this issue of un-unlockable bootloader. HTC, Samsung, Motorola, Nexus all have now-a-days techniques of unlocking bootloader somehow. Besides, how is it a justice to let one variety of G4 to be unlocked and others not? I don't get that.

Btw as you know I had 2 dead G4s at home. Today I took both of them to the local LG customer care. The one with warrenty was repaired by replacing motherboard within half an hour and another one wasn't lucky as LG refused to repair it.
[G4 General] mohitgalaxy3:
That costs a bomb bro almost 2000 MYR, first i bought LG 818N for 1500 dual sim variant and sold it in 7 days as i thought I will easily get H815.

However after trying everything I couldn't get H815 with warranty so had to take the korean model.

I will sell this **** again and buy MI5.
[G4 General] dontpannic:
Why?

Problem -> Warranty -> Solution

If you send it off and get it back in a reasonable amount of time (which I suspect is the case), then why is this a fiasco and enough to not trust LG any more?

They've admitted that there is an issue, offered to repair or replace under warranty, what more can they do?

Just remember that LG don't just make the G4, they also made the Nexus 4, Nexus 5, a selection of very good watches, the G2, G3. They have one faulty component on one model of phone. It can happen to anyone.

I know of plenty of people who had RROD's on their xbox 360's - were they "done with" Microsoft after that?
[G4 General] CiViCKiDD:
Mine bootlooped but their repair status says s/w emergency download. I'm getting it today but a little skeptical it even works and worried if it does, it can die any day now.
[G4 General] One Twelve:
ok

how long is good back up for you ? mention sot and runtime.

depends, this camera is the best at it. otherwise manual is an easy option and here its manual focus that nails it.

hmm, its quite loud.

options for front facing speakers are dwindling. so requirement is for a good speaker. G4 definitely qualifies.
[G4 General] spartan268:
One things for sure. The PS4 is currently destroying the XBone in sales. Maybe this is reflective of a few people being "done with" Microsoft.
[G4 General] dontpannic:
Probably more that the ps4 is a higher specification device for a cheaper price. But let's not get into that one.
[G4 General] One Twelve:
Has LG officially launched the G4 in your country ? Can't see any mention of G4 on their

website

.

So you bought an import before LG officially launched it. You have to be a serious phone fanatic to take this risk. kudos :good:

LG has no obligation here. What good will a petition do then ? this is really black & white for them, limiting liabilities.

it means 505's are the cheapest to buy wholesale :mad:

i keep telling people that are interested in G4 to avoid that serial# or to ask for serial before buying.

Remains to be seen how long for others will continue to do so.

The latest nexii come with a fuse that gets blown the moment you unlock the bootloader. There is no way back and your warranty is gone. But you can play as much as you want.

What is complicating matters is the finger print scanning BS. Which can then be used for pay. This requires added security and hence more lock down. You would think devices that don't have a fingerprint scanner are not required to have this level of security.

neither do I. By doing it only in one place it means any problems that come out are limited to just that one place. If there are no problems then going beyond isn't a problem. My hunch is they don't want any problems. So once the G5 is out then any untoward publicity of the G4 isn't going to affect LG too much. This means things could still change in the future. Its a slim hope but its just that. Hope.

Ah, so G4 is officially available in your country after all then :)
[G4 General] mohitgalaxy3:
: I meant sound as in headphones.
[G4 General] nipun1110:
Hey first of all, it's nice chatting with u. Yes G4 is officially available (although after 2-3 months of official international launch during which I bought the first one :p). Thing is, I was a hardcore HTC fan before G4. Till date I believe HTC flagships are the best made devices around here (not talking about specs). But in my country HTC had no warranty although I never faced a single hardware problem with my previous 3 HTCs. And all those were rooted and unlocked, so it made me somewhat fearless about buying devices without warranty, but alas....
[G4 General] One Twelve:
What are using for source and what are you listening with ?

Go through this thread.
[G4 General] Astur_Torque:
the have to repair it because the problem was when you buy the phone
[G4 General] spankmatic22:
I just got my g4 last week. Wow nice phone. Got it used on eBay. It is a 505. I asked LG if it is covered by their warranty. They said no so i bought a square trade warranty through ebay. Scared i will get boot loop but i will run it as long as i can and then see how it goes. Wish me luck!
[G4 General] doomalikaw99:
I read your post 2 days ago,I said to myself:"no it can't be!my phone is 6 months old and still working".

An hour ago,it started bootlooped...SO ****ING PISSED ATM!!!Can't seem to find a way to recover my data,if anyone know how to please tell me.I don't know if the big core disabling method works because it's saying only for lollipop and I'm on marshmallow.

S/N 608

is there anyone with bootloops on S/N 608
[G4 General] raptorddd:
last was a 604.
[G4 General] zirahel:
i have seen some posts where poeple complained about bootloops on 607 but didn't find a single post for 608 so i wonder if they fixed it there already
[G4 General] 350Rocket:
If it has happened on 607 models then that's a long time since the first batches, so my guess is that it's never been fixed at all. 608 were built very recently so just aren't old enough to have failed yet. Mine is a 607 and I've only had it for a month or so now. I am not going to root for a year in case it fails and i need warranty.
[G4 General] raptorddd:
wich variant you have>?
[G4 General] 350Rocket:
Mine is an H812 Canadian variant, from Koodo mobile. There is absolutely no carrier bloat pre installed which helps.
[G4 General] nikomedes:
Mine is 505 and I am using it since December. I had ghostscreen issue but not bootloop problem yet. I am trying to burn it by playing pokemon go with 100% brightness. It closes after high temp warning, I am doing it maybe 10 times in a day but I could not manage to force it to bootloop.

I am not sure if I am lucky or not. My warranty will be due at the end of this month. I hope in next two weeks I will have bootloop issue.

Do you have any other suggestion to expedite the process to force it to have bootloop?
[G4 General] Riardon:
Why you want to break it? Maybe it won't boot loop ever. If it didn't already. Not all G4's suffers from the boot loop. If you are insisting on breaking it though assuming the loose connector is at fault and assuming your phone has a bad connector to begin with then overheating could do it. Play intensive games at sunlight. This can overheat it.

Hello everybody. I have also a G4 from June 2015 and I had after 9 month the same bootloop problem. I had a 505 version. My phone was unlooked and rooted. I had no problem to repair it and it came back with a new platine with ser.numer 605. Everything was fine. When it came back I unlocked my phone and rooted it again. It works after that great. I have an officials rom only rooted. I have the problem right now that my phone makes 3-4 times a day a softreboot. I do not know why. I think there is somethi g wrong with the platine. Maybe s.o. has the same problem. Thank you

Gesendet von meinem LG-H815 mit Tapatalk
[G4 General] nikomedes:
Actually my concern is the possibility of having bootloop after my warranty is over. Of course I do not want to break my phone but I also do not want to pay money for mainboard replacement because of bootloop.

I think I've explained the situation.
[G4 General] 350Rocket:
There's just as much chance that it would have lasted maybe 6 months or a year past warranty but with your stress tests maybe it will last a month past warranty now. It's just a gamble really
[G4 General] gallego18:
Flash a custom kernel and underclock both big cores could avoid a possible future bootloop??
[G4 General] 350Rocket:
It certainly couldn't hurt.
[G4 General] john306:
Oh well it final happened, boot loop on a 15 month old G4, I've sent it in for repair, hopefully no problems as I never rooted it or bootloader unlocked it.

Crazy thing is my daughter's 8 month old G4 had the exact same boot loop issue the very next day after mine... Hopefully no problems repairing her's either as that's been left standard too.
[G4 General] equiliym:
i guess news from my side, after a month, today i got a call and my G4 is repaired and on the way back, they told me the main board was replaced, no one mentioned anything about the warranty or unlocked bootloader.. now the question is, as far as i know, there is a rooted image that i can flash without unlocking or should i risk it and unlock for a newer version of android.. i didnt really notice much of a difference between 5.1 and 6.0.. however i dont know what kind of warranty ill have from now on so would prefer a rooted image with locked bootloader
[G4 General] QuickNET Tech:
Welp, my G4 (LS991) model 509 bootlooped as I was was preparing to make a backup of the files on the device. I was cleaning out junk files before I copied what I wanted to my PC and the phone froze for a few seconds and then turned off. At first I thought that SystemUI or something else system critical had crashed, but it refused to boot back up and I then knew what had happened. I love how life can be so ironic. The phone had so many problems leading up to the failure. Severe degradation in battery life, overheating for no apparent reason, pixels along right edge of display that would turn white and then back to normal in a very random manner (almost like static, but not as noticeable. Just one vertical line of pixels that would sometimes do it, but I couldn't discern a pattern of when it would happen and when it wouldn't.), near instant pixel retention, screen off swipe down gesture not working or if it did, it left the display on but all black (causing double tap to wake to not work, battery drain and overheating. Had to hit the power button twice to get to the lockscreen), constantly dropping wifi connections, constant lag spikes. I thought that I was just being paranoid about the device being near death, but I guess not. I just find it funny that it happened before I could pull my stuff. I found that sticking the device in the freezer for a few hours would allow me to boot it and keep it on long enough to pull some files. I usually got about 5 minutes of functionality before the device would heat up and die again. I did this twice and was able to pull everything I needed from the internal storage.
[G4 General] redentor666:
After poor headphone speaker sound,red color retention on display,bad responsivity touch screen,overheating,lags,my H815 505 series has has died by irreversible bootloop after thirteen months of agony for me,will not miss him and i will remember him by nothing.Still have eleven months of extended warranty,so in agreement with the dealer i will try to replace it with a toaster or washing machine
[G4 General] larsdennert:
Doesn't matter what kind of cell phone. Everyone should be prepared to lose the entire phone at any time. Make sure your contacts, calendar, tasks, game data and other apps sync to the cloud. Back up photos using google photos, Dropbox or OneDrive. Turn on Google backup in phone settings to backup apps and other settings. Turn on Android device manager in the administrators section in case it gets lost. Set a lock screen password. Encrypt if you have really sensitive stuff.

My 505 series G4 is bootlooped today. It was on my desk and suddenly restarted, then stuck at LG logo. I am lucky that I got a back up 2 days ago.

But I am unluky also, because my warranty is over.

I will push LG to take an action as tjis is not my fault, it is a manufacture issue which LG is responsible.

[G4 General] ZephonWave:
Finally happened to me 2 days ago. Bootloop on my LG G4 H818N (Hong Kong), serial number 506, bought in august 2015.

I was kind of prepared for it, after following all these disscussions about it.

What makes me angry is the support from LG. I called the support center in Hong Kong, and all they told me is that since it was bought more than 1 year ago, it is no longer covered by the warranty. It would cost 150 HKD (~20 USD) to CHECK the problem on the device, and if the problem was the motherboard, the fix would cost around 2000 HKD (~250 USD)!!

That's it, no more LG for me. With so many chinese brands making decent devices at a much lower price point, the least that LG could do it provide a good support. I liked the G4, specially the camera, but this is a dealbreaker. Never again.
[G4 General] jest30:
I actually hope mine loops again. It first did in may 2016 and if it loops again until may 2018 i will get new phone or so they said.

My 511 G4 looped a few days ago (13.08.2017), bought late november, 2015 (so almost 2 years old now). I'm currently waiting for a response from the store.

If they refuse i'll try some of the methods posted here on xda - stil can't decide between cooking the motherboard and shutting down the high-performance cores. And i'm hoping i don't end up having to choose... :p
[G4 General] Minto107:
If store refuses it, try to contact LG, if they won't take your phone, say sh1t on their Twitter, they should contact you and replace phone ;)

Anyone facing random reboots with 508 serial?

Anybody who is using a G4 and hasn't backed up their important data deserves to lose everything. Manufactured date/serial number doesn't matter, back your stuff up.

Hi there,

I'm considering buying a new G4. Does the new ones still come with the faulty motherboards¿
[G4 General] starfcker69:
Yes and the serial number should be on the outside of the box. I doubt there's old stock still around for sale.

---------- Post added at 11:58 AM ---------- Previous post was at 11:14 AM ----------

You might be right but you can't look at your experience and extrapolate that info and come to the conclusion that all 505's will go bad. You might be an outlier - just rotten luck. BUT the fact remains that our G4's with SN 505 -508 have a lower resale value than later dates. And what happens once they are out of warranty? In the US the warranty is one year. Will LG or the carrier still do repairs if it goes into bootloop the 13th month, or the after 2 years?

LG only makes around $1USD profit per G4 so I could almost cut them some slack on this. Almost...
[G4 General] Nexus 4:
Sorry but I might have missunderstood your message. You mean that there are still some chances to get a faulty one with the new ones?

Cheers
[G4 General] touns_j:
508 here , stock Marshmallow, locked bootloader , no random reboots issue

there's a poster in the bootloop thread who said his G4 510 serial went into bootloop so i am not sure it's only 505-508 that are affected
