Hello to all of you who's reading, I ask for help from all of the skillful and knowledgeable folk in this wonderful community, I have a LG G4 phone that ran on CM.13, everything was running fine up until two days ago, phone just froze for a minute, nothing was responding, it crashed and LG logo came on, attempting to power on, but 10-15 seconds later it goes blank and lights up LG logo again... Now I've tried getting into TWRP but factory data reset msg comes up, after hitting yes and yes screen lingers frozen for another half a minute until LG logo shows up. I can get into download mode and tried flashing a stock image with LG Flash Tool 2014, it looked like it went through successfully but ends up doing the same thing... loops without ceasing. Do any of you have any idea what is going on and how can I get it fixed? Thanks for reading!!

Yesterday I was backing up my phone through the third party recover screen when my phone shut off during the recover (I think I may have hit the power button?). Now when I try to start the phone when it's not plugged in I don't get any response from the phone. I can get to the fast boot screen but selecting recover mode just leads to a grey screen that says google on it for a second then the screen shuts off. I tried the LGNPST recovery method but the phone gets stuck in a loop at 67% where it shows the LG logo, the screen shuts off for a moment then back to the LG logo again. I've tried all the methods I can get my hands on, does anyone have any alternatives?
I thought I'd update this so that people that google their symptoms and come here have an answer.
I can't link to the youtube video but its called "Disconnect Battery LG Optimus G Sprint"
Pulling the battery fixed everything after installing the stock rom from LGNPST
Thanks to the folks in the IRC for help!
So I have an, I beleive korean h815, I have been rooted for a couple weeks now, nothing else done to the phone. Today all of the sudden it stays on the LG splash screen. Very occasionally it'll start up and say "android is updating" but then it reboots the splash again. Is there a way I can just wipe everything and start like from factory again? I've tried the factory reset from the power+volume screen, I got to that screen, but it didn't do anything.
correction, it says twn on the box, so i'm guessing it's taiwan.
I found the thread on using LGUP to install kdz's. Went with the 20c kdz. Phone went to restart and it's just sitting on the screen that says LG. No animation or anything. Someone please help.
I had to buy am LG g stylo to get me by. I really want to fix my g4 and return this thing.

Can you tell us your android version? I think i have exactly the same issue which is quite annoying.
Each night i put my phone in the power plug with flight mode ON. In the morning, when i remove the flight mode , the phone restarts and falls into bootloop. Happened 3 times exactly the same way. I went for PCB replacement the previous week and i got a PCB starting with ser. No 601xxx. Today morning when i removed the flight mode i got a bootloop again. I am sure that this is caused by the V20D version that i installed the last days.... LG messed up again...i have a bootloop each week..
Not sure. But this is staying on this screen, it doesn't restart and stay on.

Hi, I have an LG G3 VS985 on 47a (according to LGUP) and I recently tried installing an OTA update that I have been putting off for a while. During the update I got an error that froze the updating process so I pulled the battery. After pulling the battery I can not get passed the LG logo in the beginning. The logo will show up, turn black for a few seconds, vibrate, then restart again. I tried downgrading using the TOT and KDZ methods but kept getting a no ks version error or some other type of problem. So then I decided to use the newest 48a KDZ file and LGUP to update/overwrite what I have installed right now. The process starts and the phone shows that the installation is working but when LGUP gets to the point where it has to restart the phone (about 80%), it just keeps bootlooping instead of going on with the installation. I tried clearing cache, factory resetting, and everything else I can think of. I read that the bootloader might be corrupted? If that is the case, how would I go about fixing it? Thanks in advance.
Edit: Another strange thing happens when I plug my phone into a charger from the off state. Instead of showing how much battery is charged, it just shows a loading circle on the battery picture then proceeds to restart into the loop (without me touching the power).
Exact same problem I'm having
1 difference my led light does not work . Is there a fix? Need help
Hey! Check the bottom for TLDR.
I have had my G3 since they came out (have the 2GB, 16GB RAM version), and even got the G4, but remained with the G3 since it didn't have any issues with rooting and recoveries...
Anyways, I was talking to my brother on WhatsApp yesterday and ended up checking out my Hangouts messages at the same time. I believe I accidentally hit the camera feature on Hangouts, and then everything froze. I could still talk to my brother, but I could not get to the home screen or even change from looking at Hangouts. I turned off the screen in hopes that I could get back in, but when I turned the screen back on, I could not log into the phone (I do not have a pin or password, it has no lock at all).
After a few more minutes talking to my brother, it suddenly shut off. When I tried to turn it on it went into a bootloop where the front light changes different colors, and the LG logo continues to show that shine going around the logo.
I was able to get into download mode and went ahead and tried to flash a KDZ as per instructions (I have done this in the past). The install would complete and the phone would give the prompt about updating all the apps. Once that was done, it would show the LG logo and again for about ten minutes. Afterwards, it would get stuck in updating all the apps again and performing the same process...
I also tried using the LG PC Suite and trying to "Restore upgrade errors", but every time I would click that option, I would get a Windows error that something happened and close out the program (it never recognized the phone). I then used the LG Mobile Support Tool, which allowed me to perform an update for the firmware. It too completed, but then went back into the process of updating apps, showing the LG logo, then looping.
The final thing I tried was doing a Factory Reset. I was able to get to the area, and when selecting yes, it immediately went to the LG logo and "Life's Good" sign, which it would never get passed. This is also what happens when I try to turn on the phone and wait.
I contacted LG, which was pointless, as I expected. They wanted me to go to a local repair shop, which is of no use to me if they can only perform the same things I have done.
TLDR: My phone can get into download mode and the Factory Reset area, but flashing stock firmware, or performing the Factory Reset, still leads me into one of two bootloop situations. LG PC Suite and LG Mobile Support Tool seem to be of no use.
Does anyone have any suggestions? Is there anything I can try that I haven't?
Thanks in advance!

Well my G4 (VS986) has been running ok on 13b rooted since december 2015, and today it suddenly died, it was on my desk and when I tried to use it the screen was black and it won't turn on, something like this had happen before but I usually just remove the battery and voila it had it working again. But not this time.
Now It only goes to the LG screen and then it turns off again (but it doesn't bootloop) so I keep trying then I connected the phone to the charger and it tried to boot again and this time it went to a black screen saying Secure Booting Error and it was error code 1007 but it went off again.
Then I tried to access recovery mode and it can access and be there for 40 min and it wont turn off, however I can't put it on download mode alway when is connected to the PC it says "qhsusb_bulk"
Anyone have any idea on what happen and how to fix it.
Thanks.
