How to tell if your G4 is susceptible to bootloop? - Sprint LG G4

I just acquired a used LS991. Can I tell from the ESN if it's susceptible to the dreaded bootloop? (It's running version ZVG).

its a g4 it will bootloop not if but when
if u got the box theserial will be lik 506 7 8 610 the higher the num the newer it is

Don't have the box, so that's out. Didn't I read someplace that later-production G4's did not have this problem?
So, no way to tell from the ESN it's manufacture date?

Bassicly nov 15 and later are much less prone. But have been reports of bassicly all. Doing it.
Biggest thing i tell people is hve a backup device just incase. Regular backups. And Dont use while charging. Its a heat buildup issue. And mine died after 2 years and 3 months due to true mechanil failure not bootloop. And it was a 506 or 7 most common one

I bought one of the first LG G4. Should I be worried?

I bought my G4 August of 2015. It is dated 05/2015. Serial number starts with 505. I read on xda that batches 505-509 could be bad. Should I get additional warranty on this phone? Do I have until date of purchase to invoke the warranty in case of failure? Or does the warranty end 05/2015? What would you recommend?
Thank you
Yes get the warranty. It's better to be safe than sorry. Not every phone made on those days are bad but you always want to be ready just in case.
I'm in the same boat. Bought mine the day it came out in April. Been using 6p for a bit and heard about all the units just self destructing for no reason. That is thoroughly ****ed up. This is grounds for a class action lawsuit. What is causing these 'events' with the g4 frying itself? And what should I do? I purchased April 1st 2015

Whether you can get an extended warranty at all depends on where you bought it and in any event extended warranties must be purchased within 30 days. You may already have an extended warranty if you paid by credit card. If you are the original owner of the phone and have a sales receipt LG's warranty is valid for one year from the date of purchase.

The bootloop are random and reports say it's due to a bad connection on the mobo which is the part that LG replaces when you send it for service. Some users say the phone will restart randomly a few times before actually looping so if your phone randomly restarts one day back it up and be prepared for it to loop. Doesn't mean it will but it might and better safe than sorry.
I've had three warranty exchanges already... So including my original, I'm actually on my 4th G4.

LG has acknowledged the issue and should fix it. Carrier phones should be covered under warranty till it runs out.

2gb ram instead of 3gb

Just noticed my phone has 2gb of ram, not 3gb
Anyone know why that is?
Before anyone brings up it might be a clone, its an original lg g4 T-Mobile h811
Where did you buy it? I was considering getting one from ebay...says it's bnib...I wanted to upgrade from my lg g stylo :/
What is bnib?

Mine is not purchase from eBay
If it is brand new in box you should be good? I'd message reseller and ask just in case and ask him if it is sealed and specifications are all the same
Where is it coming from?
The only problem I see is you open the box, and find out it is a clone.
You could always put a claim return to it. Reseller might argue it was sealed but your point is valid
If it is coming from China I wouldn't bother
Bought a lg g2 once. Seller did not claim it was bnib. When I got it you could see the extra glue that screen was replaced
Try local
Nope it's coming from new york not china luckily...idk though now I've been reading about this boot loop problem the g4 has...I'm wondering if I should just stick with what I have...I use my phone everyday for work and really don't want to risk an issue...not sure what to do really :/

Ask him for first few numbers of the serial number
Post back
A lot of the issues are with the 505 phones. Some have never had a problem even then
If it is a 505 you are taking a risk
Ideally you want 7 series number if you are taking it with no warranty
First 3 numbers year month
505 is 2015 may
708 would be 2017 august
I know no one is going to be selling there phone with a serial number listed..... But atleast you know your getting a 7 you are getting the newer motherboards
No one has exact info on which are known to bootloop. You might get lucky with a 505, or you might end up pissed off
The newer the motherboard/serial number less risk

Need some advice please...should I get a g4?

Hi all...I'm sorry if something like this has been posted before...if so please link me to it and delete this.
I have the g4s little brother, the LG g stylo (metropcs), and I was thinking about a slight upgrade. I found a bnib tmobile g4 on eBay (located in usa not china)
My current phone is stock rooted 6.0 with xposed and I have everything set just how I like it...I also use my phone everyday for work so it's very important that it works flawlessly.
I've been reading about boot loop issues with the g4 and that worries me...I'm also worried about this whole thing I've recently come to find out about xposed not working on nougat? But I suppose I could just stay on a mm based Rom? I'm also trying to learn about magisk as I didn't even know what that was because I really haven't tinkered with this phone in quite a while.
Anyway I'm wondering if anyone here has any good advice/knowledge to share with me...any links that could provide good reading material would be appreciated to catch me up to speed...or if maybe you can suggest another phone to upgrade to? The g4 I found was $140...but I'd probably spend up to 250ish? The g4 is just sounding like a good little upgrade for less than what I paid for my stylo new...plus I'd still get to use g4 tweaksbox...If you've read all of this I appreciate your time thanks.

depends on 2 things... 1 if its really a h811 ive seen many and inside motherboard is another variant..
2. its not guarantee but as long as you get a phone made from 2016 onward the better. doesnt mean it could not bootloop but chances are slim. i have 1 from jan 2016 anyhting above that manufacturing date . less chance to bootloop also LG has extended warranty to 2 years from manufacture warranty so they say.

i think its allowed if not will know LOL
by real what you mean.? the only way to tell if its a h811 is by opening phone.. and look at motherboard model number.

well the only way i guess is to ask the seller for manufacturing date. tell them some units are defective and you want to look for the phone with newest manufacturing date. cause if you get one and its from 2015 are very likely to bootloop.
This isn't coming from New York
Read it fully
Coming from hong Kong or china
Likely a refurb

"Charger is WDT expired"

Hey guys, so I've gotten this kernel panic that's resulted from apparently this "Charger is WDT expired" and I've googled haven't found a single thing save for the deep discharge issue. I haven't been affected by that (or have I? I've been to 0 with device powering off 2x since new & no issues w it taking charge) . Does ANYONE know what this means? Let me note that I am rooted on samfail v2.5, U2 BL, BQL5 build and BQK2 baseband.
Also, I just was informed by the "Samsung phone info" apk that my battery health is only @ 49.45%(??? Got the thing brand new at the very end of November) Does this mean that I've lost just over FIFTY percent of my overall capacity that Sammy claimed would retain at least 90% at one year of use? Any help/insight would be greatly appreciated due to that and the several kernel panics I've had would mean that battery IS unhealthy then I need to make sure i start on getting a replacement ASAP. Thanks in advance guys.
If you have had your device for under 14 days then I would take it back for a replacement unit.

You didn't read the post at all did you?
If, root is no problem for warranty purposes, go asap to claim warranty

Question Zenfone 8 suddenly died - no sign of life - Asus EU support not covering because of an unlocked bootloader

Hi,
A week ago I was using my < 4 months old Zenfone 8 while traveling in Germany, and at 19% battery the screen turned black. I went back home, tried charging it for as long as possible, it was staying cold and never showed any sign of life.
So I opened a RMA on Asus Belgium website (as I am from Belgium), and shipped the phone to their repair center.
Today, I got an email from them, saying that the warranty wasn't covering the damage, and that I had to pay 500,28€ for a replacement of the motherboard.
When going into their OOW website, I saw this table :
Warranty start:2021-05-16Warranty end:2023-05-15Issue date:2021-09-13Receive date:2021-09-15Charge reason:OOWCustomer agree to quotation:Charge reason:OOW - Out of warranty ASUS Product Unlock Flag-oow scratched
It seems to me that the "unlock flag" is their bootloader unlock tool, that I had indeed used to root the phone before, and wanted to try a few custom ROM - which I actually never did since there were none at the time. Of course, this is completely unrelated to the issue, as it is not even rooted anymore and I basically did nothing with it.
As I am from the EU, I saw that there are laws that protect consumers from these types of abusive behaviors from companies, as explained here https://piana.eu/root/
I am therefore
1) looking for people who had this problem with their Zenfone 8 (what is it actually? never seen a brand new phone die like this)
2) looking for people who had their warranty denied for an unlocked bootloader in the EU, and what is possible to do
Thank you very much for your attention and for your help
There loads of people that has the same bricked state:
ZenFone8 stuck on waiting for flashing full ramdump
As requested by the mod - opening new discussion for the issue. The Flashing Full Ramdump happened to me too - the phone was being charged over the night and the error was waiting when I woke up. I hope that at least your service will fix it quickly.
zentalk.asus.com
I had it on my 1st ZF8, complety dead. Sent it for repair but ASUS refunded it.
2nd one seems resistent to this bug, rooted, flashed all kinds of roms etc, ended in ramdump state but can always boot to fastboot.

I've seen that but I'm not sure it's the exact same state, as for me it didn't even display anything anymore. Also, did Asus refund you even with your bootloader unlocked?

Yes, it was bootloader unlocked.
You can also check state when you plug it to computer, even with dark screen.
Check what the usb connection says in device manager

Yeah I tried it back when I had the phone (since it’s now hostage at Asus) and nothing showed up in the device manager
So update: After a bit of back and forth emailing, I finally got an answer: « Im really sorry but our answer will not change. By using the unlock tool you have agreed that the warranty will be dropped, no matter what problem you are experiencing and regardless of how the problem arose. »
So basically they openly agree that they are scamming me of 500€ after selling me a faulty device, but thanks to an abusive clause, they think they can do it.
Great customer service, always a pleasure to give business to such a great company as Asus… I’ll get my lawyer involved now, anyone who has advices on the legal process in the EU is very welcome.
Seem to be some hardware fault with the 1st batch. Really bad customer response from asus, loads of reports of dying zf8's now

I really hope my small 128 GB phone won't have this issue. I really like this phone...
There are reports on Zentalk forums of both 128 and 256 models dying
We are basically all held in suspense wondering if our phones will die or not. Personally, I have a second phone (Xperia z5 premium) that is fully set up and I can easily switch in case of problems, but it is still not a nice feeling
Possible battery failure. Inspect.
I dont think its battery fail, seems more likely that storage or RAM gets corrupt, the 1st state is
"waiting for flashing full ramdump". I have this state on my 2nd zf8 but can always reboot to fastboot. That was not the case on the first unit

I haven't found the cause. My phone is working normally.
However people on Zentalk forums which have sent their phones for repair have reported that the service report has information that motherboard was replaced. I can't confirm or deny this

Was the 128GB model for me, we still don’t know what the issue is.
If I can’t get the phone fixed the legal way I think I’ll pay the 60€ to get it back unrepaired (because yes, I have to pay for that) and open it myself to try and find the issue. Maybe I’ll be more competent than their lame service at identifying the issue

Oh man I feel sorry for you. In Germany, they'd have to prove it was not their fault in the first 6 month after buying
