[Q] G2 goes black after tried to update using LG Flash tool

I have a serious problem with my LG G2 D802 which I could not solve: I used the new LG Flash Tool 2014 , everything was going just fine till I received an error recovery failed, I disconnected the USB cable by mistake from my G2 and afterward I saw that it was in the middle of flashing process (49% was completed). I turned it off and tried to reach download mode again and nothing!, I'm receiving the "LG" logo and nothing- the screen goes black (it is still on).
I tried also to connect my phone to the computer- I received a list of 13 "new" local disks "H" to "T", only "H" disk is available and it's showing "image" folder with list of files.
I cannot reach "download mode", nothing is working!
I hope anyone can help me.
Itried pressing power and volume button down together and aa lot more don't know how to slove.

@sandeep1421 Hi, you can still fix your phone using this guide: http://forum.xda-developers.com/showthread.php?t=2582142
But, Read everything carefully, Download the right files for your phone and do everything good, if not then you could hardbrick your phone if you forgot/didnt flashed an file.
So goodluck :good:
P.S. Ubuntu is recommended for this guide.

Excellent tutorial! Thank you! Phone is working again
You can stop the "unable to mount..." error messages from popping up by disabling
the automount feature of Ubuntu.
"To enable or disable automount open a terminal and type dconf-editor followed by the [Enter] key.
Browse to org.gnome.desktop.media-handling."

Nexus 7 stuck and keep loading the OS with X symbol.

Hello, a year back I had a problem of hardware in my tab, after restoring the hard ware the service center person installed a mobile version of OS.
the tab was ok but when I tried to install a system update, while install I got a error and from then the tab never starts it stuck at the X symbol.
I have tried to reboot the device by doing boot cache clear option, not worked.
I tried by using the adb as well the I am getting the message Verification failed.
As I am not able to use my tab I could not set the USB debug mode.
Can any one please help me in the above issue.

I've heard of a problem with the flash component becoming corrupt after so long. It could be that but did you try fastboot commands on your computer to see if it shows the device?

Hello ZionFreak,
Thanks for your response, yes I have tried with adb devices command which don't show any device, I have downloaded the Nexus tool kit, when I tried to unlock the device it says that no device is recognized. Please help me in solving this issue.

Mobile not starting but detecting in PC. Help!!!!

I was trying to flash CM11 ROM in my Samsung Galaxy Ace GT-S5830, for that I have also installed CWM 6.0.5.3. While flashing ROM from recovery it failed with some error message, I tried it once again and again it stopped with the same error message. I decided to try some other ROM and kept mobile on side to search new rom, the mobile was still in recovery mode connected with usb for charging, after a minute as I saw at my mobile it was not in recovery mode, the screen was OFF. I tried to restart it again & again but failed, I even tried to start it in recovery mode but failed. Tried overnight charging, thinking that its battery is down, but failed to restart it. Then I searched about it on google, and came to know it was bricked with solution to flash it with stock rom using Odin, if it is still getting detected in PC. My PC is still detecting my mobile, tried flashing stock rom using Odin, but it is getting stuck at "< 1 >setup connection...". I don't know what to do now. My mobile is not in warranty, so no way in getting it repaired from service center. If anyone know any solution for this, then please tell me. I am eagerly waiting for your reply. Moderators, please don't delete this thread saying to go and search for same kind of threads, I have already done that & at last posted in new thread. Please Help me as soon as possible. Thanks..

Extract it, open "S5830_Odin+Multi+Downloader+v4.38.exe" then in the OPS section select the .ops file in the extracted folder, then give a check on "One package" check box. Then on the bottom press the "One package" button and select the firmware in the folder and you're done !
P.S. If that doesn't work, try reinstalling Samsung USB Drivers, removing Kies, switching cables, ports or even PC's (if possible)

Stuck in Boot, fastboot locked, no adb sideload

Hello,
I have a Nexus 6P stuck during boot on the white google logo. Apparently it happened during an update to N.
I have attempted a few solutions I have found either on xda or on other pages but the gist of what I’ve attempted so far is thus:
I have tried to reflash android stock after obtaining it from google : https://developers.google.com/android/images (MTC19T) but the oem option was unchecked so “fastboot flashing unlock” returns with an error.
I have tried to apply an OTA update, again I obtained the file from google (MTC19T) , via the recovery > apply update from adb . But it fails. The error from the phone is:
Code:
E: failed to verify whole file signature
E: signature verification failed
And on the pc side I believe that the failure comes from the fact that my pc has never been connected to the phone via ADB, so it’s unrecognized.
- I have also tried to bypass the adb pc signature issue by connecting a usb flashdrive to my phone via a usb-c adapter but the mount /sdcard command doesn’t work.
I’ve tried a few more esoteric solutions, like booting into Emergency Download (EDL) but my phone just boots into the google logo and stays there.
A few informations on my device (according to the fastboot/recovery screen)
Code:
BL: angler-03.51
Baseband: angler-03.61
Product/Variant: ANGLER-ROW-WN1
6.0.1/MTC19T/2741993
Current Build Number: MTC19T
So, to summarize: Fastboot is locked and won’t work, ADB is unrecognized and using a usb drive pretending to be an sdcard doesn’t work and I’m working with a stock recovery.
I'm looking for a way to bypass the fastbook lock or the adb verification. Or (even better) for anyone here to tell me that I've been going the wrong way all this time and that the solutions involves three easy steps...
Thank you!

Try again but you have to use an OTA that is newer than MTC19T. You still may be able to sideload when recovery is in ADB Sideload mode. There is no way to unlock your bootloader. Make sure you are using a recent, known working copy of ADB/Fastboot. The problem many people can't overcome is that they never set up ADB before or used it on a few occasions, so now the phone is dead they can't get it set up correctly. When the phone is connected in recovery>>ADB sideload update, what returns when you run "adb devices"? Do you have another phone you can use to confirm your ADB/fastboot setup is installed correctly?

Download the Nexus toolkit and then boot into recovery and select on the toolkit "softbrick" , good luck. Private message if you need any help

Hi,
Thank you for your answers.
@v12xke For the OTA after trying MTC19T I downloaded and tried half a dozen images from Google. Previous versions, next version of marshmallow, a few of the nougat versions. The results were exactly the same.
As for adb I just updated my Android studio, and it's not the first time I've used these tools. The process of sideloading the zip always stops at 47% but I can see that adb and the recovery are communicating.
Fastboot devices also detects my device, but I don't have my computer on me right now.
@DavidSantos I already tried the toolkit but it just launched my phone on the Google logo and got stuck there.

Yes, I did that. The soft just makes my nexus reboot to the Google logo.

@v12xke: Looks like there are also more and more of those bootloader + recovery access bootloop. With sideload OTA fails...
@Hipstronaute: I have already seen one or two users with the same kind of problem and if I remember, nothing fixed the problem.
Good luck...

Might be a special edition Nexus 6P , oh well. Mine had the same problem and it worked just fine

That's too bad. Sounds like the storage memory going bad and the write process is interrupted when it hits that area. Thing is, I've heard the same OTA write failure occurring several times at 47%. Wonder what that means? Anyway sounds like @Hipstronaute is looking at a replacement phone, under warranty or otherwise.

Samsung Galaxy Tab A(10.1 2019) SM-T510 soft-brick

Hey guys,
im sorry if the topic doesnt fit here. I am new and not a techi. My Son just tried to flash some custom ROM on our Samsung Tab A and somehow bricked it. It is not possible for me to get into Recovery or Download Mode i have already tried all Button-Combinations. It just shows an error saying "An error has occured while updating the device software. Use the Emergency recovery function in the Smart Switch PC software."
I have already tried with draining the Baterry empty (described in forum thread here: https://forum.xda-developers.com/showthread.php?t=1478361) and plug it in to get the Charging symbol. But it doesnt happen. It just shows only the Error..
So i really dont have any more ideas how to get into recovery/download mode.. Is there anything i didnt tried??
It seems like the download-mode is not available. Is there a way to "install" a new one??
edit: it seems like this IS the download-mode.. anyways i think i just need the stock firmware for this model T510NZKDDBT. I cant find it via duckduck/google..
Maybe someone can help me with it?
Thank you

I know I'm a year late, and you've either figured this out or moved on, but maybe I can clear this up for anyone else in the same situation.
I stuffed up and got the same message - "An error has occured while updating the device software. Use the Emergency recovery function in the Smart Switch PC software."
That error message screen is basically the download screen. Windows (and the Smart Switch software) won't connect to the tablet while that screen is displayed, but Odin will.
You can bring up Odin and re-flash the stock software (or whatever you need) while that message is displayed. If you still have trouble, holding power and down-volume will re-initialise the download screen, though it will still display the same "emergency recovery function" error message.
I hope that's enough of a description to get people out of trouble!
