Sorry for all tje typos my loner phone has a crackes screen
Hi,
I've searched over xda and google before but haven't found anything relevant so I've decided to post my own problem.
My G4 freezed unexpectedly while listening to music, I had to remove the battery to put it off.
But it never passed the LG logo again.
So, i've been stucked on this LG logo, looking for an answer and found about this hardware issue but I'm not certain to get the same error.
It's not a bootloop (even if I sometimes got stuck in bootloop while trying everything to revive my phone), I have been able to get to the download mode and TWRP (which I don't have anymore because I went back to stock using LGUP and LG bridge), even though I hardly get to the download mode now (I sometimes manage to do it though). I've also managed to save my data when I've managed to enter TWRP (plug in, remove battery, push volume down + power while putting battery in) which, people with hardware issue haven't, as far as I know.
I've tried everything I could and wouldn't even be able to describe it all.
Do you guys know how I could be sure if it's hardware or software related ?
Last try: update via Lg Bridge, succeed but still stuck on LG screen.
Thanks a lot !
Flash a lollipop kdz via LGUP, then try the ILAPO (works only with lollipop, no marshmellow) metod, there is a thread on xda.
There is a video on youtube too

Thanks, I'm going to try this and let you know !
I gave a look on what you've suggested, but is that going to let me use the phone or only backup ?
From what I understood (and I might be wrong), this only allows to backup because the phone would be worthless...

You'll be abble to use the phone, but it would be slower duo to the fact that with ILAPO you disable the "2 more powerfull" cpu cores... this metod let only 1 core active from the other 4, if you want to use the other two you have to gain root permissions and install an .apk to reactive the other 3. It's a litle triky but better than nothing I guess ��
PS: if you dont want to deal with all this bulls**it send it to LG
Same problem
This morning my Lg G4 also got stuck in boot Lg screen. Did you manage to fix your issue or got the data backup ?
sometimes flashing stock LP firmware fix it.. sometimes you must send it back to LG for repair..

I managed to backup, it's a weird trick and you need to have TWRP installed I guess:
- Remove the battery
- Plug your phone (I used my laptop but I'm guessing it also work directly from the charger)
- Push volume down + power
- Insert battery holding those buttons
I managed to enter TWRP and backup with this.
It didn't work at first, I had to try it several times.
I also read you have to keep holding volume down + power until the phone reboot itself once, and then you get access to TWRP but I tried so many times differently I don't remember which one worked best. Anyway, it worked for me that way.
I didn't fix the issue and I sent it to LG... I'm so frustrated, it's been 10 years I'm into this stuff and I always managed to fix everything
Hi guys,
So my G4 just came back from LG, they replaced the motherboard and that's it... A bit disappointed to not having been able to fix it myself but at least, it worked.
I didn't have to pay anything since it was a hardware defect, LG took care of it.
Thanks for those who tried to help, I hope this post would be useful for some with the same issue.

I'm having this same issue out of the blue. Is your serial number one of the infamous "before 509" ones? I'm on TMo with the H811, so it may not be similar at all....but I'm at my wits end. I've never had a spontaneous boot loop happen to me before now. It was always something I'd done.

Indeed, my serial number was 505 something.
I've been there too, if it's spontaneous, it must be this hardware defect...

Interesting... Especially since mine was a 509 or something. I guess they missed some units. Oh well, I just JUMP'ed early with my TMo plan to the G5. That was my second G4 after a similar issue 13 days into owning the first one back in November. Having your phone spontaneously die is quite a fun way to spend your anniversary -____-. I wasn't about to give that model a 3rd try. Thanks for replying.
Good evening everyone,
I come to you guys with a very particular problem. The LG G4 in question is an H815T (Asian variant). Let me clarify right now, it was not bootlooping. This one was getting STUCK at the LG logo, it didn't restart to it multiple times, it just got stuck there one day after turning off by itself. It did go into the download mode, though.
It went into the first part of the recovery, but when you selected that you wanted to factory reset, it got stuck there. The only way to get it out of the logo or the stuck recovery was taking the battery out. Interestingly enough, the phone DID charge at the stuck logo, albeit not so much due to the screen being constantly on at full brightness.
An even more interesting fact... I managed to fix it! I flashed the KDZ corresponding to the latest LP for the H815T, after the process was done, it did bootloop. I found the YouTube video about flashing a certain file to deactivate most of the cores and said "what the hell have I got to lose?"
Flashed the KDZ and.... VOILA! It showed the Recovery Android doing its job at Format Resetting !
Something even crazier... The phone booted into AndroidLP, I was worried about the cores thing, but the phone seemed to work at full speed... I was surprised to run HWmonitor and notice that all of the cores were active. The phone was fully working!!! Or so I thought... Now I have TWO problems:
I cannot update to MM. If I try to update from the phone itself (because it does say there's a new version available) I go back to being stuck at the LG logo.
When I make a call the screen goes off... nothing I do will turn it on, and if the other person does not hang up, the phone will remain locked. However, if I plug in a headset everything works normally.
Is there anything I can do about these two problems? Please, leave your comments and questions, I think this phone is pretty weird and I found nothing else like it on YouTube or here on XDA.
Take care :good:!
Idk for the call but for the mm you could try using something like lg mobile update tool... Something like that.
Be warned cuz i dont know if it will bootloop.

Got it! The sensors thing was definitely it for the screen problem. I also read this is very common with many screen protectors in 5.1.
Do you have any ideas regarding the issue updating to MM?

All good, Willy! Even is you're stuck at the LG logo, take your battery out, or it back in BUT DON'T TURN IT ON... Instead, try to access DOWNLOAD MODE. If you're able to do it, you can flash any KDZ you want, but be careful.

Yes ur right using a heavy screen protector will block all the sensors so ya try removing it... No issues in MM u can try OTA through wifi

your screen protector had the sensors covered . you need one with the cut out in the speaker and sensors..
hello everybody
recently my H818p G4 , just got in a bootloop out of the blue , I tried all these safe mode , hard reset , .. nth works always freezes at one moment so I decided to reflash a KDZ
the thing is , the phone sometimes gets in download mode and sometimes it doesn't just like there is no battery inserted won't even boot with battery in and fully charged
the times when it gets into download mode it starts flashing and then it just reboot and stuck in LG logo in the middle of flashing process.
I used both LG flashtool and LGup softwares .. and same problem every single time
any fixes to this ?
Your phone has developed bootloop issue just like hundreds of us here (thus there is no need for another thread) so you have 2 options though ultimately it will be still repair job for LG if it is under warranty:
1) Temporary solution to disable big cores and try to recover the data if it is of any importance and you can have phone working for some time but it will be slow:
http://forum.xda-developers.com/showpost.php?p=67550617&postcount=1273
2) RMA your device to LG to have motherboard replaced

but the link u gave me , talks abt H815 mine is H818p .. would it work still ?
update
I successfully flashed it using LGup software .. all went aright , 100% ... phone reboots then comes that green android robot , then comes LG logo for a while and then everything goes black , like phone totally shutdown
Of course it won't work as per my post above. Hundreds of posts on this so not sure why there is a need for you to be different and create new thread? Is the search button not working?
Everything you need to know is here: http://forum.xda-developers.com/g4/help/recover-data-bootlooping-phone-t3313869
Download the files and read the instructions, it does say what models are supported and what not. Big cored disable tool is not a guaranteed way that you'll recover your phone but if it is outside warranty then you have nothing to lose.

Hi hope you can help, I'm trying to fix my sisters phone that has developed a software fault. The phone is completely stock, never rooted and I believe its on lollipop but cant switch on to be sure. Her fault happened when on snap chat to a friend and the phone just cut off and kept boot looping to the lg logo.
I have tried booting it into android recovery by holding the power and volume down button together, the re applying this when the logo appears, instead it just shows the battery charging.
Tried opening it through sdk manager in a cmd command of "adb reboot recovery" and still nothing.
When plugged into my pc it tried to install the drivers but stops after 2 mines and reboots.
Is their any way around this issue or to at least boot into recovery? its the LG G4 H815 model.
Thanks
Didn't it just bootloop? XD it's typical issue for 2015 G4s???

Search for boot loop over here there are multiple threads!
If your serial (sticker behind the battery ) starts with 5xx you have the hardware issue hundreds other have. Repairing is the only option to fix.

Thanks for that here is a picture of the sticker under the battery. I think it does is this one of the hardware effected ones?
see attachments for photo

Yes you have a 505 and so it seems you have the infamous bootloop.
As long as you have warranty send it to LG for repairing
There are guides here how to backup with the freezer method of you want to.

Thanks you have been a great help, its my sisters phone so the freeze backup would be perfect as she has photos on their she wants to backup. Have you got a link to the best guide to follow? Also final question. If it is under warranty for them to fix she has smashed the phone screen and has been cracked for almost a year (don't ask why she is living with a cracked screen because even I don't know haha). It still displays and responds to touch (prior to bootloop failure) and the intention was to get her phone up and running then replace her screen for her. Even if the damaged screen has nothing to do with the cause of the bootloop screen will LG dismiss this and refuse repair because of a faulty screen? In which case am I best replacing the screen first then shipping the phone off to LG repair that way they cant dismiss the screen as a cause.
Thanks

Cab you just boot into the recovery and clean the cache partition and see if it reboots successfully.

Thanks for the suggestion but sadly tried that with no look. her battery isn't great either doesn't hold much of a charge. Phone is in a mess really and trying to fix it for her rather than a shop or company charging her an arm and a leg. It just goes to the LG logo then the battery logo then nothing.

This can not be solved with deleting cache.
Google is your friend!! Here is the"link". :

Besides that check my signature... the first line. Really.. :silly:
Well to be honest if you can I would replace the screen first just to be sure that this will make no trouble when sending it to LG. Jm5c
