Bootloop after restart - G3 Q&A, Help & Troubleshooting

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

please help on a bricked/dead i780

Hi all experts,
I am a newbie on this. I am in Canada, since here we dont have i780, so I brought it on ebay and didn't realize its not really an unlock phone.(been cheated) although is sim free but GPS and many other 3rd party app don't work. so i was looking for solutions and found your thread here.
I followed the flashing guide and everything seems to be ok until the russians rom is flashed. The phone turned off itself and cannot turn on anymore. I have tried holding ENTER and FUNCTION button, solf reset hole, and Start + End buttons to turn it on but it doesn't response at all.
I have spent my hard earned $500 on this phone and i am so depressed now... Please kindly help me on fixing my "not just bricked, but dead phone" or i have to save up for months for a new one... sigh..
your response is highly appreciated
Jack
I feel your pain and I had the same issue as you before.
Phone won't turn on after flashing and the mirage reported the flash was 100% done.
I suspect this is due to the samsung modem driver was not installed properly. I had forgotten to do a reboot after the driver install or it might be due to something else.
The way I fixed it was to send to ther service center as it is still under warranty. They had to replace some chips to make it work again and I think that might be your last hope.
thanks for your advise. I did install the samsung modem driver and did reboot the PC before starting mirage updater..... but somehow turn that way.
I brought it from ebay, do you think it can still be warranty? anyways.. gotta try my luck.
thanks tho
I just contacted Canada's samsung service centre. They said They dont have this model here in Canada, so cannot fix my phone.
Please, anyone can give me a hand?
What about a hard reset? have you try it?
try to re load the rom.. i am using HH1 for phone and HH5 for the PDA... works good... with the russian ROM PU (if i am not wrong) i had to load few times as the process stopped at 80% or so... and u can load the ROM from this thread without loading the PU rom..
i have the same troubled too~~

When flashing my KS20 in emergency mode, after ~10 sec the LGMDP said something about an QCSBL writing error, or somethint li that. I pressed OK too early
Now my phone doesn't work, can't turn it on and no emergency mode. What can I do now?
Take out the battery,insert it and do a hard reset.

1)Wrong thread.Please do not post irrelevant things.
2)Download my guide and you will see how you can hard reset.But I cannot understand why your phone hungs up!I do not think this has to do with opera.I have opera and it works fine.
Help! My LG KS20 is dead!
I have tried searching, but nothing came up.
Yesterday while flashing, it said something timeout (1st time the bar runs across)
Now, I cannot activate emergency mode. I cannot charge the phone. There is no response, no light. Charging the battery full has no effect. Taking the battery out has no effect too.
Is there any way to fix this? My warrenty expired just yesterday

Very strange problem!Maybe your battery is dead Take out the battery and connect the mobile with the pc.If nothing happens then it is not a battery problem.Have you tried a correct hard reset?By saying correct, I mean holding the 3 buttons for many time until the leds flash and then flash out.Then you must release the buttons.
Thanks ibanezman for your reply...
Nope, nothing. Battery is fully charged (I have an external LG charger that was given free).
Nothing happens when I remove the battery and connect to computer. I cannot do a hard reset, because there is no LG logo, and no lights. Not green, red, or blue.
I can't flash in emergency mode, because holding down Internet Explorer and Power gives nothing. No usual green light. Laptop doesn't detect anything. Nothing in device manager.
Today while going through the logs in the LGMDP folder I came across this.
<AppName>Log For Web DownLoad</AppName>
<TIMESTAMP>20090908235324</TIMESTAMP>
<Date>2009-09-08</Date>
<Time>23:53:24.-473</Time>
<IMEI></IMEI>
<TIMESTAMP>20090908235324</TIMESTAMP>
<RESULT>FAIL</RESULT>
Notice there's no IMEI number? Could this mean anything?

I do not think this has to do with IMEI.Maybe you have lost your IMEI in the flashing process.But I believe your phone is dead/bricked
I really cannot feagure out any other suggestions.Maybe you should take it to LG Service.

Hi.
If you have tried the Hard Reset and it did not work then I have to ask you if you are still under shop or LG Warranty. If you are take it back.
It may seem obvious to you my reply but it is so. If you can return it you do not want a problematic phone right?
However:
If you do not have the Warranty any longer then your best and perhaps only solution is to flash with a computer <preferably windows 7> a KDZ or TOT+DLL file. This will flash the LG stock firmware back into your phone and eliminate this issue and make it like when it first came out of LG factory.
Be careful to READ and understand very well this process. YOU MUST choose the correct KDZ or TOT file for your model. If you flash the wrong file for your model...goodbye LG G3! Do not be in a hurry until you completely understand the whole process.
Below is a link to an XDA thread where you will find LOTS of help in doing this. The OP of this thread @hyelton is a really nice and helpful guy and has helped thousands of people. Just head over to the thread, first READ the OP and then post your questions and you will get help.
If you have no Warranty do this. Be patient and YOU WILL get your beloved G3 fixed.

[H815] Stuck on lg screen, no bootloop, access to download and recovery ok [SOLVED]

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.

AM i Bricked or not?

Hello all!
My wifes sister let some idiot at work mess with her LGG4 , Anyway he tried to flash a factory kdz to the phone, i believe he pulled the plug before it was done. Accidentally he said, i think he tripped over the cord, moron. So, she brought it to me, ive been able to salvage most electronics she brings to me, but this one has a secure Boot error 1014, cant find any info on it. i can get to recovery but the options there do nothing but bootloop, download mode gets as far as the first download mode screen then bootloops. any insight in to what is going on would be greatly appreicated. thank you and sorry if im missing any info.
Edit: So the guy tried to flash 10b over MM to "start fresh" and accidentally pulled the cord out before it was done, anyway to recover this phone?
nothing?
Trying to go from anything back to 10b is a no no. As far as I know you're probably bricked. If you have insurance, use it.
I remember downgrading off certain higher rom numbers to lower ones will always result in a hard brick and there were some limited exceptions. So be careful

I too have a g4 still under warranty, can I send her g4 and get a replacement? If I call them and tell them it's bootlooping?

I'm expecting same problem for over a two months, it happened without any previously signs: I typed SMS as usually and got black screen, after two seconds phone restarted itself and I got same error as you (1014).
There is no fix yet, unfortunately, but you are lucky, you are under warranty. Also I had previously this problem described on link here
