Hey there
I'm new here and didn't know where I should cry about this problem.
I just dropped my phone and the battery popped out. Now I've got one of those "bootloops" I think you call them, that point where you get stuck at the LG logo blinking.
I think I got that bootloop because I modified a bit the "mixer_path.xml" to push my volume on the headset, if not, I don't know what happens. Now my question, what should I do? I don't mind if I have to do a hard reset, havn't got nothing important on the memory. But still, I can't do a hard reset with the hardware keys. Now my question, can I do something with that piece and a computer ? I read that you can "repair" it with LG PC Suite or something but I just can't find the button for repair . I can enter download mode if that's important to know but nevermind. Nothing else. Please help me asap.
Thank you
Greetings !
You softbricked it. Which variant is it? HERE is a guide for the Sprint version, but you must use the .dll and .tot for YOUR version of the phone.
sent from my LG G3
I've got a spanish one, unbranded, European common I think
I'm on T-Mobile, and I upgraded from a G3 to a G4. Ordered the G4 from T-Mobile yesterday, got it a few hours ago. Earlier today, I went through the restore process for the G3 using the LG Flash Tool (essentially following these steps here). That all went fine. Shortly after that, without thinking, and without closing the LG Flash Tool, I plugged my G4 into my computer to charge it. I got confused for a moment when I noticed it restarting. The Flash Tool had picked it up, and was setting up to push the G3 firmware to it. I panicked, and unplugged the phone from the computer, right as the phone went to the "Firmware Update" screen. Now, whenever I turn it on, it just goes straight to "Firmware Update". Won't enter recovery mode, etc, etc... No matter what, just "Firmware Update".
Any help?

You done goofed OP. i dont think g3 method works on G4 from what ive heard. can you try to hard reset the phone? or if not connect to computer and use the terminal or ADB(i think its called) to restart to boot to the recovery menu

Well, it has the same download mode as the G3 (which is unfortunately the only thing it will boot into), so technically I should be able to flash the firmware the same way, only problem with that is, because it's so new, the .dll and .tot files aren't available anywhere.
I tried a hard reset from the phone, didn't work. I couldn't get ADB to pick up the device (since it only boots into download mode), so I couldn't reboot into recovery via ADB
Took it into a T-Mobile store, they couldn't do anything, as expected. Notated my account, and said to call. New phone was ordered and being sent out to me, should have it Monday

well at least your having it replaced. did the replacement cost anything?
sorry theres no fix to this right now. but i think its a little too early to mess with the G4
You have to restore you LG G4 to stock ROM.As your device is bricked you can't Flash via recovery.Download & Install LG Flash tool on your PC.Then download LG Stock Firmware according to your device model number.Then Flash via LG Flash tool.Below i share some helpful links
LG G4 Stock Firmware (Flashing Guide)-->>http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848

Actually there was no need to go to the store and get a new phone
You can easily flash G4 KDZs via LGUP, if you're stuck in download mode. Easiest game of your life. Sorry, that you had a lot of trouble, but keep in mind, that there's a way to get out of bootloops and such 99% of the time (well in fact 100% if it's a software problem). For future problems just check this thread. Easy to use, easy to get out of bootloops. Cheers

Thanks. But this was back in May, about 24 hours after it launched in the US. KDZ's weren't available then. Otherwise I would have done exactly what you said

Oh sorry! I'm a bit late then :laugh: Didn't see the date.
Long story short -
Tmobile G4, tried to root it, bricked; authentication error #11.
Got it to boot up to the download mode, followed this guide (http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848); got the Sever Connection error, everyone said that was fine and to let it run... I did.
The LG tool got to 100%, the phone turned off and well... it's never turned back on.
Windows gives me a chime when I plug it in but nothing happens on the screen, I plug it into the outlet and it wont boot up, remove the battery just incase, still no dice.
Did I totally kill this phone?
EXACTLY what happened to me. I'll be following your thread!

This is a classic hardbrick. I am guessing you had 10n on phone and the kdz was for 10h. The downgrading of software is a nono on lg g4. At the moment, lg is the only 1 who can fix this.

So he just has to take it to the service centre and they will fix it ?
Yes

I downgraded from 10d to 10c without problems on an H815 after exFat support broke. What exactly is not downgradeable (system, recovery, boot, bootloader? My guess is the bl) and which variants can't be downgraded?
Nevermind, just found this -> [PSA] **WARNING** DO NOT TRY TO DOWNGRADE YOUR G4 BOOTSTACK (in USA at least)
@ThatsMajor I know it doesn't help, but for the future, make shure you do enough research. This could've been avoided.

Let us know how it goes at the service center.
if they bring it back then you did not 'kill' your phone
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.
Hello there, First of all i am new here, This is my first post here... well let's continue with my problem.
I bought a LG G4 about 1 month ago, everything was going perfectly, but 2 days ago it start to install a new android version on the phone, it says a new update was there, so i tried to download it... Everything goes ok and then my phone start with problems, i can't unistall any app because my phone restart, can't do a password because it close, can't use my phone like always...
So i tried to downgrade my phone to a previous android version, i tried this method: http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
I used the kdz method using LG UP, i downloaded the firmware (PR H810PR10a_04.kdz) so i decided to follow the step in the thread mentioned before, everything was ok, it show up 100% and say complete, so i decide to unplug my phone and tried to power up, so what's up? My phone died, i can't make it power up, can't access download mode, can't acess factory reset or anything else, It doesn't power up using power on button, tried to charge and does nothing, PC don't reconigze it...
So maybe i bricked it, Is there any solution to this? As i need help... I am afraid of losing my phone as it was working amazing before.
Thanks you in advance.

Just give another cable a try. Maybe it's just the charger. Otherwise you may be another victim of the motherboard issue. Which serial? 5xx?

Pull out he battery and you will see the serial. If it starts with 5xx your chances are big that you're another victim of the main board issue.
Check the other threads regarding bootloop and if you wanna recover your data try the freezer or oven method (search for those here)

I have read others thread regarding the bootloop issue but it's not my problem... The main problem is my phone is dead... I can't make PC to recognize it, can't put chargers, don't even give any sign of life to power up, LED don't power up... So how can i do any of these methods when i can't make it awake?
Thanks you.
Me too, my phone doesn't turn on anymore, please help
Any solution to this please?
Your phone is proably refurbrished, and it have no all h810 parts inside. So proably it's not H810, and you flashed image for this, that's can be problem. you have to disassembly your phone and check parts.
I buyed it new so it's not refurbrished

It's an Online shop, I bought it directly of a trusted seller so i am sure it's new... The problem come when it start updating.
LG is having a hard time with dead phones, one of my Nexus 5x just died... It just died and will need to send it to repair.
