Hello,
I tried to unroot my phone from SuperSU, my phone restarted and started to do smth in the boot screen. Now there's a LG logo on the screen and the blue light is slowly blinking.
It did so for like 2 hours then I gave up and tried to reboot. Power buttons didn't work so I took out the battery for a second and then tried to boot it up, it went back stuck to the LG screen, has been so since.
Now it has been like 4 and a half hours. No idea what to do, can't boot safe mode or anything, always the same boot stage stays.
This is called a Bootloop, if you have a custom Recovery like TWRP, try flashing another ROM (you will lose all your data).
If you don't have a custom recovery, you can Re-install the Stock Rom, take your time and read this Guide, it is simple and explained step by step: http://forum.xda-developers.com/showthread.php?t=2785089

I tried the second method from this link ( http://forum.xda-developers.com/lg-g3/general/guide-root-method-lg-devices-t3129197 ) with a tmobile lg g3 on 5.0.1 non rooted. Followed the steps and and everything worked good. final step was to reboot the phone and now my phone is not booting up. I am just stuck at the LG life is good screen and it flickers and fades to black. please help. I don't know what to do.
When i try to get into download I get that little box that say download mode but then after that it is just a blank screen. Please HELP
I was able to restore 20G back in my G3. But now the screen goes black within a few seconds. But the buttons still work with the black screen. I think I am still soft bricked. I am not sure though. Any help or advice?
Bricked LG G3
Is your device rooted? Can you open TWRP? If you have TWRP you can go in and install a custom rom.
I'm having problems getting my phone past the bootup screen. It first loads the logo then goes to the animated logo then the rethink possible animation and then finally gets stuck on the glowing samsung logo. It then shuts off and redoes the loop a couple of times until it stops with the battery charge up screen and freezes there until I remove the battery.
History: Purchased an att phone for the mb to replace my original phones because it had the insane chip. Had to root it to be able to unlock the phone with my carrier(telus). Since I was in it I flash the DN4 custom rom and everything needed into the phone. The phone functioned fine for about a month and then frequent freezes and restarts started happening. Near the end, the phone was stuck in a boot loop, loading into the DN4 animation boot screen then shutting itself off then on again to endlessly repeat the loop.
Present: At first I was able to get into TWRP and tried some things in there but nothing happened. When there I notice it stated "internal memory 0"-not sure if this means anything.
I was able to flash the saved recovery file from TWRP. Once I did that I could no longer go in TWRP and now have to use the samsung install/recovery.
I have since flashed the stock rom several times with odin and also wiped data/factory reset many times still does the same in bootup. Tried flashing TWRP into phone using odin 3.07 but failed.
What should be my next move? Pretty new at this so I may be missing something very simple or perhaps a dead phone???
Finally got the phone to boot up and run fine. It seems everything was good except the battery was acting up.
Next step is to get the battery to charge when phone is off.
I'll post this question in new thread.
Hi,
Today while browsing my stock LG g4 (h815) suddenly rebooted. It showed the LG boot screen for a while but then ended up with a black screen. The power button does nothing. If I remove and insert the battery the power button works again, but I get the same result.
I can boot to (stock) recovery OK and if I connect it to a pc it shows 100% charge. I tried using recovery to reset everything but no change.
I am on holiday so can't easily send it in for repairs. Any ideas? I do have a Windows tablet pc with me with ADB on it.
Search "bootloop" in G4 forum.
Warranty is the only solution.
But this is not a boot loop? It seems to boot normally and then goes to a black screen, it doesn't reboot. I direct about the boot loop but from the videos I could find it looked like it kept booting.
I guess I was wrong trying to start it today it boot looped a few times before the black screen. Guess I will try disabling the big cores so that I will at least have a phone until I get home.
So I recently bought the Korean LG G3 (F400) and the first thing I did was rooting it, which was a breeze. Of course to root it I needed to install the LG Mobile Drivers, which I did and were working completely fine. Then I decided to take a little risk and attempt to flash CWM recovery (I did not know that I need to unlock the bootloader first or BUMP! the device) and well, flashed it the same way I flash stuff on my previous Samsung phones.
So now, when I try to boot the phone, I get the LG Logo and goes through with the boot animation, but after a little less than a second the boot animation fails and I get a black screen + the LED flashing blue and green and the phone remains like that. I tried factory reset but after I click yes it shows the LG logo then goes into a black screen (without the boot animation) + LED flashing blue and red.
So I tried finally going into download mode and attempting to return it to stock via LG Flash Tools, and like I said before the drivers were installed, but when I connect the phone to the PC it gives the message "Drivers were not successfully installed" and the LG Flash Tools fails to detect the phone. I checked within Device Manager and it says the LGE MTP device "cannot start".
So I'm pretty much stuck with a phone that doesn't boot, can't flash anything via adb or flash tools and no recovery installed. Can anyone suggest anything I can do to get this beast back up?

Hello everyone,
Yesterday when I was going to use my tablet I noticed it was off, but minutes before it was on, so I tried pressing the power button and nothing happened, plugged the charger in, nothing, no signs, it seemed bricked, so I tried to power through download mode and it worked, after that I pressed volume down to cancel it to start normally, the first samsung logo showed up (that one that says the model and stuff), but it was there for really long, i left it running and after 5 mins or so it changed to the pulsing blue samsung logo, left it there and about 30 mins later it was back to the 1st samsung logo again. I also tried a soft reset and booting to safe mode, didn't work either.
This tablet has no custom rom installed (I think it is on stock 4.4.2), the only thing different I installed is TWRP and root, years ago, but I cant boot to TWRP through the vol up+home+power, it doesnt work, tbh it never worked since back then, the only way I found to boot to twrp was thru "adb reboot recovery" using adb, which didnt work in download mode, I want to be able to backup some data before flashing it with Odin, so here are my questions:
1- Is there any other command I could try to force it to boot to recovery?
2- Is there any way to backup data via download mode on this device?
Thank you for your attention
