Bootloop on brand new G4... what's your advice... send it back or fix it?

Hi,
Sorry for the mistakes, i'm french
I bought and received a brand new G4 (serial N°603XXX)
The very first day of using it i had a bootloop
I really think that a G4 is perfect for me now and i hesitate on what to do:
Should i send it back to the seller (he agrees to refund me 100%) to buy a new one or should i fix it?
the cons and pros:
If I send it back, i take the chance to receive a new one that will maybe do a bootloop after a few month or years while i'll have many data on it BUT, I may have a new phone that will work immediatly.
If i fix it, i'll have to send it to LG (actually, a professionnal tried to fix it through software and didn't manage to do it.... he told me that it's certainly a hardware problem)... for 2 weeks maybe and i'll have back a phone that will work but that would have already been "opened"... it's a shame for a new phone.
My opinion:
it's better to have a phone that is fixed than a new phone that will maybe die later.
Can i think that if it is fixed ,it will NEVER do a bootloop again?
What's your opinion, please?
Thanks

It can't necessarily be fixed, it can only be replaced.
I had my G4 for exactly 11 months (June 2015 release date through last week) before I ended up with the bootloop problem. I got it replaced under factory warranty, but it is a manufacture's defect.
If I were you, I'd just get the G5.

to buy a new "flagship" is not an option.
i hesitate between fixing it or changing it for a new one
if they "fix" it... what do they do? they change the motherboard?
if the phone is "fixed"... am i right to think that it won't have any bootloop problem?
thanks

What is it about the G4 that makes it perfect for you? What about the V10?

V10 is to big (and not on sale in France )
with my budget and all my needs, the G4 is the phone i need (compared to all the other phone with the same price)
so... what do you think about my strategie...? is it good or am i wrong?

I say exchange it for a new G4. It's not 100% certain that all G4 phones will have bootloop issues, but it is 100% certain that the one you have right now does.
The problem is that all LG is doing is replacing motherboards, but even new motherboards may have issues, as you've witnessed. So what does a "fixed" phone really mean? They're not doing any fine soldering work to actually repair the problem. If they were, I'm sure someone would have noticed that by now and there would be DIY threads on how to fix it yourself.
I would just make it a habit to regularly make backups of your phone and be prepared in case the new G4 fails in the future.
I was one of the biggest G4 fans when it first came out since it's also everything I wanted in a phone other than the 808, but throughout the course of this week, I decided that I was over it. If I'm lucky, my replacement G4 lasts long enough for other better options to come on the market at the right price, new or used.

OK. Thank you for your answer. I thought that they would install a motherboard that DOESN'T HAVE this bootloop problem but if they do as you say (install a motherboard that may also have the problem.... There are no reason to do that)
And wich phone do you think about?

You're welcome. If LG could guarantee that you would receive a motherboard that won't ever bootloop, then it would be worth repairing the G4 you have now, but if your current G4 was built in March 2016 (serial 603, after the problem was allegedly fixed) and it still bootloops, then I don't have much confidence that LG completely figured out the problem.
If I were to replace my G4, I like the LG V10 if there is a reliable root method released for the T-Mobile US version. Otherwise, I would consider the Samsung Galaxy S7 edge only after a very big discount, so that would have to wait at least a year. I like that LG still believes in removable batteries and obviously their camera hardware and software is excellent, but they need to improve the quality and reliability of their phones. Also, the G5 is a poorly implemented concept that I really don't like, so the V10 successor needs to get everything right for LG to prove they have any idea of what they're doing anymore.

So you're telling me that all the LG G4 even the new one can have this problem and that if they try to fix it, they may install a motherboard that CAN have this problem. It's crazy.
I love this phone but I don't want a phone that can break at anytime
...! ?

It's not likely, but it's possible. Recently, some users, including you, have reported that phones with serial numbers starting with 603 and 604 have gotten bootloops as well. With the original 505 phones, these issues started happening with great frequency after half a year, so we could have to wait until later this year to find out whether or not the newly manufactured G4 phones will also start showing the same symptoms with high frequency.
I wouldn't recommend the G4 anymore either, so that's why I asked earlier what do you like about it, because you might be better off finding those features in another phone. I'm just enjoying my replacement G4 while I have it, but I no longer think it's going to be something I can keep forever, like a couple of Motorola dumbphones I still have from 2006 and 2009.

From what it seems no g4 is safe. From what ive read even the g5s are suffering from this bootloop to. Several people said that ic power managment is the problem and mother board replacement are the fix. Now i dont know how far all of this goes as i have a suposed safe model and only have had 4 months.
But from a longtime lg user id got with another manafaturer. Such as a nexus.

Suposedly they are. But. Many claims that even the refurbs. Claims that the one that lg repairs. Bassicly. Rumors are no g4 is safe.

Your best bet is to buy a refurbished one which already had a motherboard replaced...just ask the seller whether it is repaired

How to 'naturally' damage G3

This question will be controversy...
In few months my G3 warranty will end... My friend who lately send his G3 for repair under warranty got back new G4.
(Maybe they were out of some parts? Doesnt matter....)
Curently I'm thinking about to check, would I also get new G4 instead of repaired G3?
So... Is there any way to damage it without leaving any hints for repair man?

This is fraud. If you want a G4, buy one. If you can't afford one buy something else or keep using your G3.

You could try a few second in the microwave (but not too much)
Edit: BUT REMOVE THE BATTERY

change your way of thinking dude, or you'll end up brutally " damaged " in jail.

Indeed. There is no comparable warranty on your rectum. Your friend was lucky. In addition, he wasn't actively intending to commit fraud. This grinds my gears...

To be honest I really like my G3 Only thing which bother me is overheating.
I will make hardware thermal mod but after warranty end Thought maybe there is a chance to solve it other ways.
Read that G4 CPU better manage thermal problems.

People like you are the reason the majority have to pay more for things such as insurance or extended warranties.
Don't like the phone? Sell it and save up fro something else.

will my g4 bootloop?

Hi, just bought a second hand g4 with serial number starting 509 will the phone possibly bootloop? Also the phone is the Taiwan model and I currently live in the UK, will having the Taiwan model cause any problems? Thanks

It may Bootloop it may not. There is no definite answer. You may have problems with a non EU model in the EU. They may fix it or may not. You have to ask an LG service centre about this.

If you ask if 509 is prone to Bootloop issue I think it is. Most bootloops happened on 505 though but the general consensus is the newer G4 you have the less chances for bootloop. Again there is no definite answer. We do not know the dirty details. We don't know which S/N is safe and if LG fixed the problem and from which S/N and after they did. We purely rely on public reports to draw conclusions. Up until now 6xx seems safe with only 1 or 2 ppl reported a bootloop on Reddit. Just make a backup and keep your data on the SD card. If you get a bootloop contact LG. They seem to be aware of the issue and fixing all broken phones even out of warranty some times.

Thanks so much for the response!!! So do you recommend I return the phone as there is a risk of boot loop and the phone is from Taiwan so they may not fix it?

yes theres a high chance it may bootloop.. and no UK wont repair your phone.. you must shipped to the country you got it from .. i say return. and get a phone with 6xx serial number.. there less reports with those serial numbers..
maybe @jinderation can chime in... hear hes story.

I'm in the UK and have the same problem - a bootlooping TWN H815. It was purchased used last year, so no receipt or warranty card. I was wondering whether you had explored paying LG for an out-of-warranty repair? At this stage I'm looking at the best way of cutting my losses.

In US cost of repairs alone is 200US$ cuz of morherboard replacement either that or which u can get a used g4 at the same price so even if ur bootloops there is no point of fixing it....all i can say for u is to wait for atleast an year after the bootloop so the prices fall down for repairs....there is no way u can send it to taiwan also there is no warranty n recepit thats only even if u have a friend there...

Avoiding heat
Hi all am in same boat. Got a EU H815 an 506 hw1.0 and until a week ago had never heard about bootloop issue. I've had unlocked bootloader, rooted with custom ROMs nearly whole ownership and as a result have never had any heat up issues. After reading 100s of pages of the issue my conclusion is that it seems to be heat that affects a soldered component which eventually fails. So based on this theory I'm using Kernel Adiutor to control the throttling when CPU temp gets >55degc. It is only an educated guess but does seem logical. Hope it helps others

Definitely the cause. I did always notice with stock ROMs Genisys etc my phone got hotter than CM and logically it makes sense so I'm sticking with it :fingers-crossed:

Seems like the issue calmed down over the winter in the northern hemisphere. And now that the summer is in full bloom people are looping like crazy. Im hoping between being almost as far north as one gets in usa. So like 85 far. Is blazing here. Plus me doing the thermal mod im keeping my device cool enough to make it as i have no waranty so a mb replacement costs me about 200 dollars american.
I have a s6 and a couple other mid range devices. I wont hesitate to toss my g4 in the trash. I got mine on a trade in from my g3 i only paid like 150 for my g4 so nope not me. Unless i get one cheap.
If this was an automobile this would be a recall i dont understand why these devices arent recalled.
I saw a news cast talking about how they make devices so cheap and breakable "for the economy" why would u buy the newest devices out if your old ones are running quite perfectly they say. So this is for economic reasoning. So go ahead lg keep making s****y devices i will buy a new one but not from you.
Yea i want a g5 but i wont give more that 100 bucks for it in the fear of failure.
Like i said keep it up lg seal your economic fate........

They are always better options than LG out there...the credibility rate for lg is always has been the worst thats why there used phones are sold dirt cheap everywhere

Hi, my G4 had bootloop recently, motherboard was changed under the warranty. New motherboard was made in 04/2018. Is it known if newer motherboards still have a bootloop issues?
I cannot found any relevant informations. Maybe because nobody already have this old phone

they are all bad as far as i know. And yes, nobody has this phone as its later revisions bootlooped after warranty and its more expensive to repair this piece of crap than what it is worth even after repairing.
I have my bootlooped G4 in a drawer since 1 year ago.

I have a phone that's never bootlooped

we cannot guarante you wich one. but i could point out wich might be less likely to bootloop.
this is whats happening it either wont loop or it may, thats uncertain. but phones that are serial number that starts with 6XX they are LESS likel to get bootloop. as far as reports theres have been a few. not like the old ones bootlooping one after another. and try to get a variant that would be able to unlock bootloader.
do a search for list of variants that can be bootloader unlocked.
