Hello. I got very urgent issue with LG G5 H850. I didnt had any software of LG on my PC nor drivers and connected G5 to pc while holding VOL UP button, phone entered into Dwonload mode for second, then into the firmware update state and its stuck in 0% for hour. I tried holding every possible button combination for 20 seconds and its not reacting, disconecting from cable also didnt do anything. There is a box on bottom with "633A B50". I installed LG bridge with drivers, connected to PC (still in Firmware Update state) and PC software cannot detect phone, i also clicked error list but it also says i need to connect to pc.
What can i do? My mission was simple, guy gived me the phone, saying "i want to sell it, i made factory reset (from system) and i forgot my gmail password". He's apple user, so he hate android, and he didnt used gmail for year or so, but seriously damm the google bypass, how to get phone up from Firmware Update state?
NWM - i just noticed i can unplug battery

Hey,
I saw many posts regarding LG E615 being stuck in bootloops. I had rooted my phone a month back, yesterday i went in for a software update.(Mistake i guess) and after the update when the phone reboots, it started going into a boot loop. I had backed up my data before i updated the phone using LG PC Suite. Now when i switch on my phone, the LG icon keeps flashing on and off. Also when i go into Emergency Download mode, it starts installing the Drivers on the laptop but the LG USB Mobile Modem driver doesn't install. I even installed the driver from external source, but still to no avail. I have already downloaded the firmware for flashing my phone altogether, but will that result in all backed up data also being deleted? Or is there any other way by which i can get my phone working? Also, i forgot to mention but i am unable to open the Recovery mode of the phone as suggested on net as Pressing Volume down+Power and then releasing and pressing Home button. Please help
Thanks
So i post a lot of threads getting help of unblocking my phone, but the replies that is given won't work
[Heres all the info what i did with this phone]
My phone is an Lg p769 T-mobile(Bricked)V20H
All i did with this phone is rooted it, to get root access to moving files.
I have a Locked Boot loader.
I Accidentally installed chain fire 3d without knowing its not compatible with JellyBean.
So my problem is I'm stuck in boot loop.
when i turn it on its stuck on Lg logo. (No Security Error)
I am able to get into S/w upgrade mode but not Recovery mode.
My PC (Windows 7 Professional) won't detect my phone when in its in S/w upgrade mode. But it shows as LG modem
Device driver software shows my phone when connected as s/w upgrade mode as Unidentified Device - Unplugged
I installed the my phone driver from the Lg websites even the latest drivers 3.8
But still its not connected
I tried following guides to offline Flashing with lg mobile support tool to flash stock rom to my phone. but still my phone won't get detected
getting stuck on 15% when upgrading.
Adb also dosent detect my phone
all i need is to get anything to get my phone working even if i have to wipe everything.
i provided images to see what I'm getting when my phone is in s/w upgrade mode and connected to my pc
Sorry I'm for my bad english
Hey bro. Same deal happened with me. I got a bootloop with a root app. How i got it to work was through sw upgrade mode. You hold vol. up only, while plugging it in to your pc. Then you can do a recovery update, and it should work then. Message me if this doesn't work. Before this though, try a hard reset/wipe. That will wipe your phone, but so will the other solution i said. Hard wipe is vol -, power, home. Release after lg logo pops up.

Hello Yesterday i have upgraded my phone ROM.
First have unlocked the bootloader.
Next, followed this video to upgrade to Android 5.0 AOPS build:30-11-2014 by Artas.
It was great and useable while i did not installed a new CWM.. (CWM 6.0.4.5 Touch by Pollos).. after that, the phone is stucked at "LG" logo and while i charge random times reboot..
Earsed all with fastboot, and now the phone is not turn on while i charge or try to turn it on..
I have got this problem earlier with an other android version (sercurity error) and the S/W update was good.

Hello

- when i volume up + power the phone nothing happen, same with volume down + power and volume up+down+power
i have installed the lg tools and using the imei downloaded a 600+MB package which should be the restore image of the phone but when the procedure starts to flash the image it gets stuck at 4% trying to connect to phone without any luck

Now.:
When i try do S/W upgrade with the "LG Mobile Support Tool", it stops at 4% and the phone disconnect itself from the PC.. the installer goes (without the phone plugged in) 4--->8% and if i turn again my phone to download mode, go to 15%.
At 15% again disconnect and the installer say "Error, try to unplug USB and remove battery and try again......"
I have tryed KDZ offline flashing but it is force quit when i click "Start"..
Tryed:
Official support tool - Say "You have already installed the latest version (V20H). If i try to "Upgrade errors fix", it stop at 15% as i said..
Fastboot - earse boot, system etc.. after that again upgrade, but stop at 15% and phone turn off.
LG Flash tool - these 90% exit with some error before i can start anything..
I hope you can help and understand my bad english:'D
Did you invoke "Download Mode"? If i remember, this requires switching the phone off, and attaching it to usb while keeping volume up or down pressed, and will show a special screen, if successful.
Download mode is even more basic than fastboot or adb, and the final line of defense, before throwing the phone away.
All LG tools require the LG usb drivers. These at least no longer recognize the phone with Artas' CM11, except for when in download mode. Then Windows should auto-install a virtual COM port. For ADB and Fastboot you need different drivers then, like those from the Google SDK. But with these the LG tools won't work, not even the sync suite.
Hello, my Z3v was downloading/installing the Lollipop firmware over night and when I checked in the morning the phone was stuck in boot loop.
Following the SONY logo screen, it immediately goes into "Error - Update Failed" and it keeps repeating the loop if plugged in to the wall charger (if not, it shuts off shortly after). I have tried recovery mode but it doesn't work (tried both Power + Volume Up and Power + Volume Down), it immediately goes to the dead android robot with "Error-Update Failed" screen and repeat.
I have tried PC Companion, however there is no Z3v in the available device recovery list, and based on the search neither Verizon or Sony is providing support for the device? which is just plain ridiculous. I can get as far as having the "Upgrading, do not disconnect device from PC" screen when connected to the PC Companion while I have to choose the restore device (again, no Z3v so can't proceed any further from here).
My question is -
1. Is there a way to access the folders in the phone to retrieve data from it? My guess is not while in boot loop since it keeps disconnecting but a way to do it on the "Upgrading" screen?
2. If I don't mind the hard wipe, is there a way to get this fixed? Verizon technician gave up after 3+ hours of trying...
Thank you so much!
Just Turn off your phone and flash it with Flashtool then it will comeback
Thanks for the reply. The Verizon technician told me he tried flashing it several times with no luck. And personally, I've never done it myself. Is there a step by step guide on how to do so? Thank you so much!!!
My V30 got an Update yesterday. It downloaded and I pressed install, hooked it up to the Charger and left it there to do its thing... After about 80% was completed it automatically restarted and now it stops booting at the LG screen. I tried pressing the POWER OFF switch but nothing happened (even after a full minute). Then I tried POWER OFF + VOL. DOWN. It rebooted, showed me some error and got stuck at the LG loading screen... Did POWER OFF + VOL. DOWN again and tried to enter Recovery mode with pressing POWER OFF again... Stuck on LG loading screen...
What di I do?
I have exactly the same problem.
The error showing is:
Your device has failed a routine safety check and may not work properly.
I contacted both LG and my carrier about it, both said that I should send it for repair, but that will cost me a lot of money.
I tried a hard reset, but it didn't seem to work.
I'm wondering if more people seem to have this problem after the Pie update, but more importantly, does anyone know how to fix this?

Unlocked bootloader message is normal. If it's stuck there then try factory reset erasing all data
I had exactly the same problem with 30b software. I was coming from 21w with all my data on there (22j never came with OTA). I hooked up the phone onto PC and ran LG Bridge where it showed that I have update waiting (nothing showed in phone settings Update option). So I vent ahead, LG Bridge downloaded 3GB update, phone restarted, update began to load. After finishing phone restarted again and was supposed to boot into updated Android 9 but got stuck on LG logo instead. Tried all button combinations but no luck. Then decided to downgrade to 21w again as that one was working before. Unfortunately for me, I left option on to refurbish the phone (all data gone). Silly me. So then I flashed 22j and left it boot. As I logged in on the phone the message popped up about new update. Software version 30b (Android 9). I left it to download (1.73GB) and updated it. Booted without problems. Just to clarify, I had non rooted stock 21w, which came after I let the LG Bridge to repair my phone as no updates were coming. It did that and immediately received 21w software. Since then I had no updates or notifications.
I have the same problem, my device is a korean V300L, boot correctly on oreo V300L21S, but doesn't boot on update V300L30D, stuck on LG logo, then I've back to oreo by refurbish with lgup.
I had the same issue, this video helped.

Took me a few tried to get it but once I did I was able to erase everything then boot. Hope it helps.
