stuck at LG logo after reset - LG G Pro 2

After upgrading to 5.0 via LG PC Suite, my phone won't knock on (but can knock off)
So I go to setting and perform factory reset.
After that it reboot and just stuck at LG logo.
Then I pull out the battery and reboot, the phone didn't reset. Then I just go to service menu (3845#*350#) and perform reset.
It reboot and stuck at lg logo again!
But this time I pull out the battery and reboot, I cannot boot into phone again and stuck at lg logo!
What should I do in this situation?
Also I have tried to reset at boot up (pow + vol down then vol up + vol down), it can show the reset option but also stuck at lg logo.
And I cannot enter recovery and i don't know why...

Can you in Download Modus? Power off,press and hold volume up and connect the Usb Cable in your Pc.Works this,flash with Kdz Tool 2014.

yup i restore back to 4.4.2 using kdz
I found that when i upgraded the phone to 5.0, the knock function is not working properly(can knock off, cannot knock on, when i turn on screen using power key, it immediately turn it of again)
When i use 4.4.2, the mobile network always disconnect but reconnect 2-3 seconds later.
Is that my phone problem?

Stuck on LG Logo after flashing a corrupted ROM file

Hi.
So I was flashing a ROM using CWR but it looks like the Zip file was corrupted. So after I selected the zip file, the phone restarted and now is stuck on LG Logo.
Anyway to resurrect the phone from dead?
Any help will be greatly appreciated.
Try power button+vol down+3d button if you can get the recovery....

Thanks for the reply.
When I hold those three buttons the phone started, shows LG Logo for a few second then turns off.
I tried LG Mobile Update tool as well, after I type my Serial and IMEI, it says "Starts downloading data..." then immidately shows a "There a fatal error with LG Update tool, please contact your adminisitrator"

When you see the logo release only the power button immediatly after 5-6 second the recovery should appear...
If you will not able to get the recovery look here:

I had the same problem and:
1) Start LG Mobile update
2) Power off your phone without USB cable
3) Connect the USB cable and wait for the LG logo and the annimation battery
4) Pressing Vol.up + power 6-7 seconde wait for the LG logo and The screen turns off
5) Again pressing Vol.up + power 6-7 seconde and wait until the drivers are installed (LG Mobile update detects your phone and the screen is always off)
Here I was lucky because lgupdater detected my phone and then said that an update was needed. Applied and then everything went fine.
PS sorry for my english...

I have the stock v10c ROM on a 'Rogers' LG Optimus 3D.
I had been using the Google+ Android client and pushed the power button to put the phone tosleep (with the G+ screen still being displayed). About 15 mins later I pulled the phone out of my pocket and it was dark, but the touch countrols were all lit up.
I know that usually isn't good news.
I pulled the battery and tried to re-boot. It gets to the Rogers bitmap and then boot-loops, with a flash of the Rogers scren each time it restarts a cycle.
I did vol+down+Power and the it booted into a recovery (3e) menu that only offered me the chance to wipe all user data. Ok. I did that. The phone then presented a triangle logo and the green android and sat there.
After about 10 mins I pulled the battery again and did the Vol+down+3D button+Power boot to the REAL recovery menu.
I then did a factory reset. I have assumed the Home button is the enter button (BTW).
Again the triangle and the green android appear. They are still there 10 mins later.
Not sure what to do now...the phone won't boot and the factory reset won't fix it. But it isn't dead. I can still get to recovery, so in theory this is fixable. I just don't have time for it right now.
I was wondering if maybe the phone had updated OTA in my pocket and i didn't realise it and I may have messed up the process. But I have never seen a phone do an OTA update without first notifying the user and seeking confirmation...so I that probably isn't the case.
Very annoying.
I'm posting this here in case anyone else has the same experience.

Did factory reset now bricked

So I did a factory reset, the tab rebooted to wipe the device, went to nvidia logo then screen went black, shuts off automatically and I can turn back on just for it to get right past the logo and shut off again, I've tried volume up with power and volume down and same thing happens. Sometimes the power won't even turn it back on for 5-10 minutes. Any suggestions?

Dumb question, but are you sure the battery is charged? I would leave it plugged in for awhile and try again. Then if it still is not booting try to enter download mode while connected to PC. Mine did something similar to this once when I did a factory reset as well. It only recovered after connecting USB to my PC.
I'm guessing you have custom recovery installed?
1. Download the factory image from NVIDIA website (specific to your device version),
2. Go into fastboot by pressing volume down and give a slight nudge to the power button (don't press until the logo comes up, just a quick nudge will do)
3. Unlock your bootloader using the instruction which can be found on this forum (if you have, skip this step) sorry I'm on mobile phone, so a bit hard to do a search for the link with small screen.
4. Unzip the recovery image zip file.
4. While still in fastboot, flash the recovery images using flash-all.bat contained in the unzipped folder.
You will lose your custom recovery and your root, but since you were gonna wipe your device anyway.. let me know if you're stuck somewhere.
I think i might have found fix....
Shut down the device with long press (8sec) Power button
Press and hold Vol down key
Press and release Power key
Device enters fastboot mode
Select Recovery mode option (using Vol up/down for navigation and power key to select)
Device enters recovery mode (after showing NVIDIA boot logo) with Android Robot screen.
Press and release Vol UP + Power button simultaneously
Then select wipe data/factory reset with Vol up/down key to navigate and power key to select
try this but be PATIENT AND wait for it to say erasing then i think ill be normal once its done also just wait with it on the "blank screen" we could have just got ahed of are selves and whent to conclusions and thought it was bricked

[Q] LG G2 Soft Brick after OTA...Help?

Just took the Lollipop OTA update from stock 4.4.2. Upon completion my phone rebooted and is stuck on the LG boot logo. I tried entering download mode (holding volume up button and plugging phone into computer) but my phone doesn't enter it. Attempting to power off the phone doesn't work either, since the phone just powers off for a second and turns back on to the boot logo. I tried factory reset (power + volume down) and after proceeding with the reset the phone is still stuck on boot logo. What should I do?

You can power off if you hold power button longer. wait till logo appears, and still hold, till it gone away second time, and hold even a little longer.
Turns off but still stuck at logo when turned on

I have the same problem with the friend who posted first. There is no way on how to get to fastboot mode and when turned on it just restarts and back to logo. Hard reset is the only thing it allows me to try but no result. Any possible way to get to fastboot or download mode??? Help somebdyy

After i flashed the Lollipop firmware, it looked like the phone got stuck with LG logo but i gave it good 5 to 6 minutes and all was fine. The phone just needed to breathe a little.

Honor 8 (L19) stuck and logo, can't reboot, can't enter (e)Recovery

Hi,
After a wrong(?) update of stock ROM, the phone stuck at logo. I can switch if off, but when try switch on into recovery (Vol- + On) LED blinks and symbol of empty battery shows on the screen.
When I attach a charger, after some time the phones start up ... then hangs on the logo.
Any idea how to reset/update/recover?......
Wojtek
Anybody? Help...
Try this if you have unlocked bootloader and frp unlock
1. First connect it charger and leave it for 30 min
2. Now connect phone to pc and long press power button until screen shuts off. Quickly hold vol- button. Now you will be in fastboot.
3. Flash appropriate twrp recovery in fastboot.
4. Now use huru updater method for firmware flash. (search in google)
But if none of this thing works and if you are still in warranty then take it to customer care

Phone won't boot after factory reset / Open Beta 2

I have no idea why, but the phone won't boot after I initiated a factory reset while on OB2. Only thing the phone responds to is when I press Power + Vol DOWN for 10 seconds. It vibrates, the Android logo comes on and then the screen seemingly turns off again.
Tried getting into recovery but phone does not seem to respond to Power + Vol UP. It did once, but did not go into recovery or fastboot after letting go when the Android logo came on.
Any suggestions?
MSM saved my bacon. Thank you XDA!
