My LG G4 received one 880Mb OTA upgrade this morning, which I assumed to be Android Marshmallow.
After step 1 and Step 2 of the upgrade was completed successfully, the LG G4 display couldn't be turned on.
I can hear incoming call ringtone and make phone calls by saying "OK Google, call ..." and sending texts.
Everything works except the display is off.
I tried rebooting multiple times. The LG boot animation didn't show either.
However, when I plug in the power cord to recharge, the screen would light up to show the battery status.
I bought the LG G4 H815 from QD_AU on eBay. I can't send it back for warranty service because they are closed for two weeks for the Chinese New Year.
Anyone knows how to fix this?
Any help would be great appreciated!

About 3 weeks ago my D855 running stock 6.0 30b flashed with lgup (phone had worked perfectly for 8 weeks with no issues) started to shut down randomly. Upon rebooting the phone would not pick up a cell signal at all, rebooting the phone would just cause some sort of shutdown loop where the notification light would pulse blue green and the backlight would remain on but the phone would not shut down. only a battery pull would get the phone back on.
I sent it back to lg and they just sent me a new battery, this made no difference.
I have installed stock lollipop via lgup and then updated to v20n with lg software update tool and it has stopped the shutdown and loss of cell signal issue but its still experiencing random reboots. Not as frequent but usually once a day. Not app specific either.
The phone was repaired because of the crack at microphone area issue, about a month before the problem started occuring.
Im on 3 network.
Its booked to go back to lg on monday, anyone else had this problem ?
Hello,
Did a software update to my LG G4 H815 and now my phone isn't working. When I turn it on, the blue notification light starts blinking and I can hear the LG welcome screen, but screen isn't turning on. No sight of screen working, even when trying to access hard reset menu. Any solutions?
Best wishes,
Siim
After upgrading the first full boot can take up to several minutes which should not be interrupted. If you had waited a long time (20 minutes should be more then enough I think) and it is still black screen you should connect your phone to a pc. Install adb drivers if you haven't already and exec:
adb logcat
The other think to check is can you go into the recovery screen? Do you have twrp or cwm installed?
After upgrading, I experienced the same issue. Took it to service center (still in warranty). They said they changed the power chip. Excellent now, upgraded to MM. They load software on their power chip too.
Sent from my LG-H818 using XDA-Developers mobile app
I updated the phone with LG Bridge... No recoveries were installed. Took the phone to service center. Hopefully get it working again...
Hi, from last six months my Lg G4 h815 started showing random black screen. Meanwhile the screen is black the phone keeps running (music, leds, messages). Sometimes I lock the phone, then I unlock and display turns on, sometimes not. I face this problem only in stock MM fw, not AOSP or LL. What can I do? Thanks
I have exactly the same issue... I returned it to LG (it is still on warranty time), but with a random issue, I think I'll have a random fix lol.
Did you found any solution ?

Hi guys,
this is the second time that LG bricked my phone. I updated my g4 and now it won't boot up anymore. Installed was Android 6.0 and the last security patch was from 2016-08-01. Software version was V20h-EUR-xx. I already had the fun of having the famous bootloop and a screen burn in, so i basically got a new phone in early 2018. Mid 2018 i got the notification of a software update (it said something like stability update and was just 50 MB big) but I didn't have the time to back up my stuff properly so I delayed it till yesterday. Two days ago I was preparing myself for the upcoming android 11 devices, so I saved my photos etc and got most of the stuff out of my phone, then I did a backup through the onboard app (LG bridge won't recognize the phone most of the time and if it does it tries to save the backup temporarily on the phone, which didn't work because of low memory space(on a sidenote wth is the g4 doing with all the memory space anyway)) and saved it on the sd card. After that I updated the phone. A screen appeared with with software update process (1/2) and (2/2) and both completed succesfully. After the reboot it got stuck on the LG animation logo, this is a screen right after the "lg powered by android" screen, and it is stuck there since. I tried to get into recovery mode but was unable to do so.
So yes I have a backup, but afaik no user data gets saved in the app backup, am i correct? This is the reason why I haven't tried to hard reset yet. I thought maybe some bright minds in this forum know a way or solution to this problem.
I have read a little bit about LGUP and TWRP but i don't know if this will help. And i don't know which firmwire i need cause there is a bunch with H815.
What I'm asking is, is there a way to restore the phone without losing my data that is still on the phone?
sry for the long text, let me know if you need additional info
greetings Johnny
tl;dr: LG is producing garbage, please help
UPDATE 1
I was able to get into download mode.
Plug the USB Cable into the PC(not connected to the LG G4)
Have you PC Powered On and Logged in
Power Down the LG G4
Press and Hold the Volume Up Button on the LG G4
While Holding Volume Up, Plug the USB Cable into the LG G4
Continue Holding the Volume Up Button After You See ‘Download Mode’
Let Go of the Volume Up Button When You See the ‘Firmware Update’ Screen on the G4
Right now I'm trying to do the update via LG Bridge and the download mode.
Funnily the update is now 1,68 GB in size while on the phone the size was roughly 50MB iirc.
My free memory space is only about 4GB, so i hope this will suffice.
UPDATE 2
The installation was sucessful but only on my second try. The first time it failed at 81%, so I did it again as I was told via LG Bridge and followed the instruction steps. The second time it worked. After rebooting I got the screen that 80 apps are getting optimized. Took nearly 40 minutes. After that I got in and did a quick check if everthing was alright, saw that some apps weren't installed, so I restarted it and the rest got optimized. Power off again, sim and sd card plugged in and power on. Now everything seems alright and if I'm not mistaken battery life has improved.
So in the end it was a failed update caused by LG and fixed by LG Bridge.
BUT in the meantime I contacted LG customer support and it turns out customer support is on par with their update policy, non existent!
Talked to a guy who didn't understand what I wanted from him, so he gave me a number where I could call. Called there, turned out it's the company who repaired my phone when I had the bootloop and screen burn in. After asking them about technical support, they told me they don't do that, they only repair. I understood, so phoned LG again. The same guy picked up again (is he the only one there?), so I asked again. This time he googled my questions and told me he can't find on google what i'm asking. I thought he has to be kidding but he was serious. No blame to this guy though, he is first level support and obviously not qualified to answer such questions, so I asked if he could redirect me to someone who could answer my questions and help me. Therefore he let me wait in the line to call a colleague so he could tell him my problem and then told me the answer of his colleague. I wasn't satisfied so I insisted to talk to this colleague of him, he said it wasn't possible because of technical reasons, but he phoned his colleague and but both phones together so we could talk (wth haha). Needles to say I didn't understand anything and I was absolutely bewildered about what was going on and the state of the LG support. I tried to convince this guy the he was of no help to me so if I just could call this other guy or be called by him would really help me. Finally he understood and gave in. He wrote down my number and five minutes later the other guy called. Well he was of no help either. Couldn't really answer my questions but could at least explain two things of interest to me. I am still shocked of the state of the LG "support". Don't they have guys who know their products and their software?
Thankfully everthing is fine now and I definitely know that I won't buy an LG smartphone ever again.
(The camera and the screen were really nice though)
