Im on Android 6 H81520A unlocked bootloader, can access download mode only, see full animation for lg logo & stuck on it. waiting for next lg flash tool
[G4 General] cjm1979:
Looks like mostly modded phones.
[G4 General] nipun1110:
That's what I thought at first. but more n more I am getting to know about the fact, it's actually a hardware issue and it's LG's fault, not users.
[G4 General] fr33kiLL:
H815 Euro BL Unlocked, flashed H81520A via zips and now Bootlooping at LG Logo , no access to TWRP :(
[G4 General] nipun1110:
I have been digging the issue. What I found is

1. A good number of people are having the problem.

2. Provided solution: Changing the motherboard or Replacement of the device

3. Rumour: G4's before September 2015 have major design flaws. Sprint has been pulling in all their devices and giving replacement of the complained devices or offering other devices.

(I have attached screenshots of a community of Sprint users)

If this is real, why we people have to be sufferer? Those who cannot claim warrenty or have unlocked bootloader will do what? In my screenshots, u will find that, some sprint guy saying that it's a known issue. If it's a known issue, why not LG addressing it publicly and helping the buyers?

I have compiled some xda screenshots also to address the severity of the problem.

Had my motherboard replaced. They also replaced the original battery. Pre-ordered the phone a month before it was released here in Sweden. So I guess I got one of the early ones.

H815, not rooted or tampered with in any way.
[G4 General] shudoha:
no ... when you unlock . or flash . its your responsability not lg . for the problem you showed on your another post . this problem was only for sprint user .. not for another brand or in europe etc etc

Got my phone in July 2015..

My phone suddenly boot looped yesterday while using google map navigation.

Was using rooted H815_V10E system image http://xdaforums.com/g4/development/h815-eu-l-p-t-sea-twn-t3176195 .

I went from original H815 sea 10a to OTA 10b to original H815 eu 10e kdz to rooted H815 eu 10e system image.

I dropped the phone at least 20times?

I installed original xposed apk on my phone but it says it wasnt supported around 1 month ago from the app itself. I didnt do anything after that.

But yesterday , i click the uninstall button in xposed app in the morning and phone suddenly boot looped in the afternoon. Download mode works , kdz original sea 10b, still boot loop. Tried to kdz original eu 10e , but download mode didnt work , hard brick
[G4 General] martin20144:
Yeah the poll can be misleading considering most people here are interested in some form of modding (root).
[G4 General] nipun1110:
Again someone is getting wrong. It's not about modding. This thread is not about only those people who went to bootloop while flashing MM firmware, rather their device went into bootloop for no reason. In most cases of modding, there is a reverse way to recover because you know the reason. But where u don't know the reason what's causing the device in bootloop, what can u do? and this thread is to find out how many sufferers are there like this. got it now?
[G4 General] the_scotsman:
LG won't touch them if it's due to being modded. You take the risk by modifying your phone in any way. LG are under no obligation to fix any faults caused by those mods.
[G4 General] shudoha:
i agree completely .. is not the fault to lg ... but the fault at user
[G4 General] One Twelve:
Update : after a week, out of 40 votes 10 were unrooted Therefore 25% unrooted affected. This is a drop from the 30-70 earlier.

leaving the rest at 75%
[G4 General] R.Suave:
Those who are having bootloops...

What month was your device manufactured? You can check on the outside sticker on the original box (if you still have it)

Mine was made in May and i'm having this problem. I think there was a bad batch made shortly before release that had defects. Here are some others with the same problem with phones made in May
[G4 General] nipun1110:
Yah mine was also in May. This device is so new that most of the devices are produced in May I guess. Then I guess how many people are vulnerable for bootloop problem. It's like a ticking timebomb, isn't it?
[G4 General] nipun1110:
did u find anny solution yet??
[G4 General] R.Suave:
I just got off the phone with LG. I told them I went through all trouble shooting with T-Mobile (up to a factory reset) and said I'm still getting them. Since it's within 15 months of manufacture date, I can send it in for repair. I'd take advantage of that if you have no other options... So it looks like i'll be sending mine in. Good luck!
[G4 General] HappyPessimist:
I ended up going to tmobile and they're initiated a warranty exchange. I should be getting a new phone by the 4th of November.
[G4 General] uxkghost:
What I have found out to work for me is to, flash the kdz and wipe the data at the same time. When flashing the kdz via LG flash tools, use the CSE flash NOT the Normal flash.
[G4 General] simonbens:
i'v already try this method but the process stop at 9% like everyone
[G4 General] R.Suave:
what happens afterwards? what can you successfully boot into?
[G4 General] shudoha:
the flashtool is not update then he can use all the solution. nothing happend like for a lot of people with the same problem
[G4 General] Culfa:
My problem this, please check solution please :(

finely my phone back alive after flash stock firmware by octopus flash box. and rooted again then flash marshmallow by flashfire app
[G4 General] shudoha:
how you did? you have a link for octopus? because it was not possible with the new version i tested . then weird

and you paid the 99 dollars for that?
[G4 General] dxbi9100:
http://www.fonefunshop.co.uk/Unlocking/octopus-lg+sam.jpg

i see on the workshop this flashbox, he flash stock 5.1 and he pay me $25
[G4 General] shudoha:
the prize on your website for octopus +lg and sam activation its 200 dollars ... lol
[G4 General] dxbi9100:
its easy for him & it's take less than 30 min :) & exactly pay him $21 lol
[G4 General] nipun1110:
what's this thing
[G4 General] shudoha:
its a software but the liscence of activate the software on the official website its 99 dollars
[G4 General] TheBledard:
It is a device (flashing box) with permits to flash MOST (nearly all model) LG and Samsung phones. When you purchase the device, it comes with nothing. You have to pay for LG activation ($ 99) and/or Samsung activation ($ 89). Then, you have either unlimited flash (for LG devices) or the ability to flash most of Samsung, HTC and Sony (+/- Ericsson) devices against credit purchased on their servers. It's a device for repair shops, but delivery is worldwide when you purchase it on the net.

From the latest version (Octopus 2.0.9 if I remember), it seems that we can flash and downgrade LG H815 having bootloop on 20A (and repair IMEI and so on).

I think ordering EDIT: Octopus BOX with Octopus activation for LG.
[G4 General] shudoha:
yes you can with the liscence . and there are not crack or serial number on the net for the new version
[G4 General] nipun1110:
Seriously guys, any H815-SEA guy facing motherboard problem for bootloop (not bootloop due to 20a flash). My purpose is to unlock the bootloader as it is supported. I want to take a chance.
[G4 General] shudoha:
my 815 is unlocked . and the bootloop come after the flash
[G4 General] nipun1110:
So I guess noone with SEA varient has bootloop or needed replacement for motherboard problem.... That's great... Probably I am gonna unlock the bootloader then...
[G4 General] releva:
My sea phone just had a bootloop and had the mother board replaced. Rooted , bootloader locked
[G4 General] nipun1110:
Can u tell me after how many days the bootloader problem occured? 2 months?
[G4 General] Enfimus:
Stock h815 here, ordered from the internet in late July. Phone started bootlooping (reboots every 2-6 mins or so) after about two months of use. It got worse, and at this point it only gets past the initial LG startup screen maybe once in 20-30 attempts to boot.

LG has been absolutely zero help-I was trying to pay them to repair it but they wouldn't even do that. (wtf?)
[G4 General] boundphoto:
In Thailand model H818P, Many people found the problem same like this.
[G4 General] maildaemon:
H815 in Europe here. The phone is rooted with unlocked bootloader and custom rom - The warranty was declined. Still trying to get to talk to LG directly :(
[G4 General] superbonto:
this is the thread i've been looking for. too many questions and inquiries regarding such bootloop problem in my local G4 forums, now i can give them the proof that it happens not only in my country's variant.
[G4 General] nipun1110:
When I started this thread, many people were very much against me. Yes I was the only one who created multiple threads on this matter and people used to blame me for that. Now I see lots of other new users complaining about the issue. Though I see hope in that, this way someday soon some media will focus on the matter but it also makes me sad that, such a great device has such a major flaws but LG is so silent about it.
[G4 General] xyannide:
cant agree more with that!
[G4 General] nipun1110:
At last.....at last... what I started, paid off or should I say, what I dreamt, came true. I have been creating posts, threads, polls etc. so that well known websites likes androidauthority, pocketnow etc. would write about the bootloop issue in their websites so that this becomes public n LG acknowledges it. At last they did it authough previously many people discouraged me n were annoyed at me.... But I took all the initiatives that I could. Now u see how many people are suffering. I wish these websites would at least gimme a little response when I requested them, so that not so many customers had to suffer. Anyway here's the link: http://www.androidauthority.com/lg-g4-bootloop-petition-669421/

Thanks to them for doing it. At last.
[G4 General] Zenouzenou:
Would be nice if AndroidPolice write something about this issue.
[G4 General] Sfkn2:
LG just acknowledged that this is an issue and has addressed it publicly. :)
[G4 General] SavageRobot:
Had it twice. Once on LB H815, once on UB H815, lets see if I get the hat trick, sick of this device now
[G4 General] Amightypotato:
It would be good to add an option for people not having this problem. So we got some relative numbers.
[G4 General] nipun1110:
Yah still u talking like this... u know what, when I started making the noise for the first time, many people were like u. They wanted to prove that not so many people are suffering. Many also told that all devices, when they first come, have problems and it's a common thing. It was kind of depressing u know!! Now see where it has come! LG has finally acknowledged it. U know what I used to say - it's not about how many people are suffering and how many are not. It's about what's right n what's wrong. Those who buy the phone, not all are rich enough to comfortably buy another phone again.. So just ignoring such a fact, which is not user's fault, cannot be acceptable. It makes me sad that still someone like you asking for such thing.
[G4 General] Huck33:
mine was Stock ROM; Locked BL; Unrooted; H815 model and crashed under MM 20C
[G4 General] undercover:
Whoa, easy there, tiger. Guy you quoted has the correct approach. It would be interesting to see what the ratio is. It would be a very rough figure, but interesting none of the less.
[G4 General] DTR204:
Stock rom, att variant 81010o rooted w/xposed

Started boot looping a week ago... Att device support is gonna replace the phone for me (should be delivered tomorrow or the next day) but I can't get the phone to boot up long enough to unroot. I'm not sure if the warranty center will even be able to tell it's rooted since it doesn't boot. But I'm still concerned about it. Anyone know what will happen if they do notice root? Will I be charged the full price of the replacement?
[G4 General] Sfkn2:
They will know that you're rooted.

After they replace the motherboard, they will have to boot up your device in order to make sure that it works before sending it back to you.
[G4 General] undercover:
Just FYI memory module is soldered onto MB. What do you think will happen when MB is changed? Memory changes too. No, they won't see root.
[G4 General] Sfkn2:
Except they don't actually replace the entire motherboard, unfortunately.
[G4 General] undercover:
That's not what I've heard. All reports I've seen so far have motherboards replaced.
[G4 General] Sfkn2:
What reports have you been seeing? LG official? Can we get access to that?

The technician who replaced parts in my phone told me that it's not the entire PCB. Please link to the reports. Thanks
[G4 General] Evnul000:
my one isnt even in a bootloop it just go to the lg logo with the one that says powered by android and turns off. But connects to pc as a different name not as my phone.
[G4 General] DTR204:
They replaced my phone completely...the paperwork sent with the phone doesn't say anything about warranty besides ' if the water indicator is lit you may be charged the full cost of the replacement...'

I think i'm good, I just didn't wanna risk it. If I remember correctly I left an unrooted system.img on the phone, so I attempted to reflash that as a precaution, but I have no way of confirming that the unroot was successful without being able to boot.

Guess we will see. I'll post back if they end up charging me as a precaution for others in the same situation.

[G4 General] djnikkofb:
I'm on vs986 (13B). after rooting, xposed, etc.. I've not seen any boot loops.

Inscribed by LG G4
[G4 General] tqwzUX6fn39GZMEzSnDF:
Can every G4 have these problems?

Any experience which parts will be changed?

Actually I don't have bootloops, but I'd like to have my G4 changed 'cause Qi is damaged and LG says the problem is not the G4 but the cover - but this is not true.
[G4 General] Makster:
Mine is a TWN H815 that I got back in July from tropical_mobile.

NOT rooted or modified in any way.

Turned itself off a week ago, and doesn't get past the LG logo ever since. Sits there a little while and shuts off.

LG customer service refuses to honor the warranty of non-US phones. SquareTrade won't honor it because nominally it's under manufacturer's warranty.

So it looks like I'm screwed.

It's good to know I am not the only one, but the whole thing did sour me on LG. Which is sad, because I like the phone and LG's features.

---------- Post added at 10:59 PM ---------- Previous post was at 10:39 PM ----------

ETA. It looks like LG has acknowledged the problem and promised to fix the phones since I last talked to them. I'll call them again. We'll see if anything changes now that it's official.
[G4 General] venom_tan:
I purchased from tropica_mobile and has this bootloop issue also .Now i tried to contact them to claim the warranty . This failure not suppose to come out with a manufacturer like LG because they already having their 4th generation devices . S**tty company i ever seen
[G4 General] IlyaKol:
Joining the club.

LG G4 H815 TWN, rooted, locked BL, Xposed installed. Was fine all night, picked it up this morning to snooze the alarm and 2 minutes later noticed it was off. Hasn't come back since.

Anyone know what part is actually fixed? Is it something I can do at home (I'm a systems engineer and have repaired a few G3's and G4's) to get a temporary fix until I can mail it in?
[G4 General] brasewel:
[MENTION=3820486]Makster[/MENTION] or [MENTION=5026624]venom_tan[/MENTION]: were you guys able to get LG to fix your phone? I also bought mine from ebay (tropical_mobile) and started having this problem back in December. I read that LG wasn't going to honor the warranty since it's an international phone but not sure now after they have acknowledged the problem. I've since moved to a Nexus 6P but wouldn't mind having a functional G4.
[G4 General] Makster:
The short answer for me is no.

I must have spent at least a couple of hours on the phone with different flavors of LG support (US+UK) and SquareTrade. None want to have anything to do with my Taiwanese phone. SquareTrade at least refunded me the full premium.

I had to deal with the Taiwanese LG. Which doesn't have a word of English on its site. Well, together with Google Translate I was able to submit a query on a Chinese form that claimed it was incomplete and wouldn't submit. (!)

I got a reply back, which I think means that I need to send the phone into a repair facility in Taipei. But no instructions or anything. I can't just send the phone to a building without something like an RMA, so I tried emailing them for more directions. No reply.

I then tried calling the number for that repair facility. All I get (during their working hours, of course) was an answering machine in Chinese, after which they would hang up.

I know that somebody here was able to talk to a human, but not me, not yet.

I think I'll keep trying, but it's not as urgent for me anymore, since I bit the bullet and bought another phone.

A $600 lesson I've learned the hard way: No more Asian phones from ebay for me.

The most I'd do would be a phone from the UK, but most likely I'll just stick to American variants, regardless of bloat.
[G4 General] Illmatic662:
If you go to the other boot loop thread I just posted yesterday and literally have the same problem you have.

Agreed, no more unlocked phones from out of the United States again.
[G4 General] venom_tan:
Not at all , i've been emails them about 2 weeks , they just replied same s**t to me : " i will check for you " , that's all ! F**K this tropical mobile
[G4 General] jcamachott:
HI everyone. A few days ago my phone bootlooped. However, I was able to hard reset it, and while in the screen to choose my wifi, it bootlooped again. This happened a few more times, then I was able to get it to login and it started to download apps. I left it like that and after about 5 mins it bootlooped again. Is the bootloop you folks experience the same? Or is it a completely non-recoverable bootloop where you can't even get to reset the phone? Someone also told me it could be the battery in my case...I'm going to test that today.
[G4 General] undercover:
Sorry, didn't see this. Won't be looking for links now, can't remember exactly where I've seen it but if you google LG bootloop fixed I'm sure you'll be able to find it.
[G4 General] brasewel:
That is really unfortunate. The only reason I bought it from Ebay was because Bestbuy didn't have the leather version unlocked. Had I known LG wouldn't honor the warranty since it was an international phone, I would have got it from bestbuy. Lesson learnt :(

I wonder if I can find some mobile shop to replace the motherboard for me, if not it's going on Ebay for parts.

That is the same problem we are all experiencing. My phone at times was able to boot into the OS but then a few minutes later would boot. 95% of the time it just keeps booting.
[G4 General] Zenouzenou:
A friend or mine just got a second bootloop...

His new motherboard was 8 months old, cant provide the S/N.

[MENTION=6366138]H@wK11[/MENTION] ... It's a sorry thing to see when a member of your apparent experience on XDA resorts to plagiarism to open a new thread. The reason your flashable zip doesn't work is because you have copied the "Meta-Inf" file word for word and comma for comma from the original by [MENTION=5365186]caitsith2[/MENTION] who pioneered flashable zips for boot logos. Not only have you failed to give him/her due credit for the work but you have also been ignorant enough to copy/leave in the three "dummy commented out" lines from his original. If you had an ounce of original thought in your being you would have seen that there was no way this "updater-script" was going to work.

Unlike you I have taken note of the requests by posters to this thread and have incorporated your "image" into a new flashable zip which works. As usual flash through custom recovery.

Might I suggest that you delete the logo and re-instate the original, I presume you backed it up before installing this one, then re-download this logo just in case it was corrupted in the download and flash it again through recovery.

You might also look back at the post by [MENTION=1608086]Stryder5[/MENTION] on page 1, he suggests the alternative method of flashing using ADB Fastboot.

Apologies first if this is a stupid question, but when I had problems with my PDAs/Mobiles the Windows seems to be reinstalled and I lost all setup/configuration.

I had this problem once with my Trinity, and I would like to make a backup of the ROM "as it is" to avoid this problem.

Is there any easy way to do it?
