hi guys I have an LG G Pad updated to kitkat officially, I have root it and I was installing the clockworkmod recovery using the recoveryinstaller.apk,
when I have tapped on flash recovery my device got stuck on black screen!!! I have tryied all buttons combination but nothing and the lg pc suite or mobiletool cannot do anything.......what I have to do?
Try to power off your g pad and turn it on again. If it get you to recovery mode, then you should connect it to your PC and try LG Support Tool to restore to factory kit Kat update.

If nothing else works, just enter Download mode and recover with LG Mobile Suite. To enter download mode:
1) With machine off, and cable plugged into the tablet but not into computer, hold volume up and down button at the same time (NOT power button).
2) Still holding the combination, plug into the computer. It will now enter Download mode. This can sometimes be tricky if the tablet won't stay off. The key is: on/off unplugged and still holding it-> plug into computer.
When you see the Download Mode on the screen (feel free to unplug the USB as it will now hold the mode until told otherwise), load the LG Mobile Suite and install the standard ROM.
Hi i tryied to put the device in download mode but the pc won't recognize it I can hear the sounds of Windows about the peripheric but the tablet continue to remain in black screen and the support tool won't recognize it.... I can try with another pc but for lg the warranty can pass with root?

Hi,
I'm in the same boat. I bought the device rooted and it was working fine, then after a day it just shut off when I was in recovery. It wasn't even while I was doing anything to it. I had rebooted into recovery from an apparently stable ROM. The battery was at about 40%. Now there are no lights and almost no sign of life at all. Occasionally when trying to connect it I get the cursor change that indicates that a USB device has connected but the LG Mobile app won't recognize it. Is there any chance that I'm just not pressing the buttons correctly? The instructions I've read say to make sure that the device is off, but I don't know how to tell conclusively that it's off. Has anyone had any similar experience, or is there something else I can try?
Thanks

Just follow the instructions above. If it has no charge, you may plug it in the wall for 15 minutes before starting.

I've done it many times but there's an element of uncertainty because I can't tell whether it's on or off. My Sony would go through some cycles of blinking lights. I'm probably overlooking something obvious. How do you tell whether it's off, or at least make a good guess?
Thanks

Hi all,
I've got exactly the same problem, maybe even worse ....
Been reading all about unbricking, updating, recovering etc ... Downloaded about all software I could lay hands on...none working. The B2CAppSetup, which is supposed to install the Mobile Tools doesn't even recognise my Internet Connection , go figure... Or is that suposed to be a fixed-line connection instead of WIFI? I've got some 'off-line-fixed-tools' that starts OK, but as soon as I point it to the *.kdz file and apropriate *.dll's, it just stops with an extract-error. The flashtool I found doesn't find any device on any port,etc etc etc ...
My G-Pad is only running in a kind of bootloop (LG-logo 2x, the death-droid, and again from the beginning) The 'recovery-mode' isn't doing anything and the only thing that surely works is 'download-mode'. But then again, Win XP sees several LGE-USB-devices which are NOT recognised by the LG-software.
Any one ?

If you are in download mode, then you are halfway there. As to the drivers, try uninstalling them and reinstalling. Then enter the LG Mobile Suite fresh and try from there.

If you hold the power button for a few seconds, you will see it go off, even if it is showing a black screen. The difference will be visible.

NVM. Misread. Anyhow, I found it doubtful that the LG Mobile Suite has issues with WiFi specifically, since the software has no way of knowing how it is receiving data via the internet. It may be an XP issue.

I had a similar issue with Sony's Emma update tool. On one of my computers (a Fujitsu Lifebook) it consistently failed saying that I had no internet connection. Another computer was fine.
My bricked LG-V500 must have been some hardware issue. I wondered if I had done something because I was flashing various ROMs, but I didn't do anything careless and it died when I inserted an SD card, not while I was performing any updates. I had just bought it on eBay and I really didn't want to make the seller deal with it (even though he had rooted and tinkered with it) when there was a decent chance that I had done it anyway. He sent me his newegg invoice, I returned it to them, and they just sent out the replacement.

Hi, I have an LG G Pad v500 with the same problem. I was trying to unlock my bootloader. Then I replaced my aboot to this one http://forum.xda-developers.com/show....php?t=2698267, following this guide: http://www.grupoandroid.com/topic/1....t-todo-en-uno/.
I have an LG L70 D325 and it worked to me, so I tried to do the same with my LG G Pad.
Now my LG G Pad doesn't turn on. My screen is black and I can't access "Download Mode" nor "Recovery Mode" and nothing else. It's seems like my device is dead.
Can someone help me?
Is there something that I can do to fix my device?
I appreciate all kind of help!!!

I know this is old 3 year old reply. But i'm fighting with same issue on my T-Mobile LG PAD V521. Did you get this fixed or could tell me how? I don't know when tablet is on or off and can't tell.
I understand it has to be off for download mode but problem is it might take long time for battery to be "off".
Thank you

So yesterday at school, I logged on to the WIFI network, signed in from chrome browser using my login credentials , few seconds later phone frooze totally.
I have pulled the battery several times, charged the phone for a lot of hours. Gave me nothing
Download mode, seems stuck at the small logo "download mode" it won't go any future.
Hard reset, dosen't progress either. When I hit "Yes" it keeps stuck at "Life's Good LG Logo"
Recover mode, my pc won't recognize the usb driver, it keeps getting "unknown driver" (Phone is otherwise dead? How to solve the USB issue without a boot-able phone) "Perhaps LG's own tool, could recover the phone, if I could solve the driver issue, maybe a manuel .sis file to install the driver?
Phone behaviour keeps staying at boot logo "Life's Good LG" No LG, Life isnt so good.
Solutions are welcome, I will probably call and use my warrenty. Because I had not installed root, messed with bulildprop, anything at all. First phone I ever used totally stock, and then this happens.
The fact it's turning on and the PC is seeing that it is connected is good. My first G3 was completely hardbricked (my fault) Just keep trying different return to stock methods.

Thanks for your reply
I have tried almost anything. There's only two stock options for 'back2stock' "recovery, & download mode" neither of them work. My pc won't regonize the usb-driver in recovery mode, so I can't use any firmware flash tools. I have installed driver and so forth.
Seems useless to continue to same two stock options, when they seem to be "corrupt or somehow damaged"
But a big thanks for you optimisme

That is very weird situation... Just can't understand why your phone bricked after logged in WiFi,...

So I got my phone back from the "repair shop" today. It said on the repair note "Mainboard replaced"
Glad I diden't use to much time trying to flash/whatever. Thanks for your support and reply.
If you experience similar issues as mention in this thread by me. Chances are you'll need to use your warrenty or replace your 'mainboard'
Peace out..
So today I tried flashing android 5.0 on my T-mobile LG G3 D851. I put it into download mode, started the flash and waited. My LG flash tool then crashed and closed. My phone was %6 through the installation however and was just left frozen after it crashed. I tried every way possible to restart it and get out of the screen while keeping it plugged in, but I couldn't...so I took out the battery and put it back in. Now nothing is turning on, I can't put it in download mode and the charging LED doesn't light up, etc. It's completely bricked....what do I do? I've already tried taking out the battery and waiting and plugging in the cord and then battery. Please help! I can't afford the insurance or another phone...
EDIT: Also the battery does have charge...although I don't know how long it will last.
EDIT 2: I just realized this flash was for the 855 variant..not 851. Does this mean that I am just screwed?
It means that you got expensive brick.
You cant enter into download mode or recovery?
Probably only help is jtag. Find someone who can do that.
Sounds like someone has learned a very expensive lesson! Have you tried to factory reset it?
Yeah JTAG is all you got if no download mode

The linked solution works only if the device shows some signs of life - atleast a boot logo.
i have a D851 that a friend bricked. She tried upgrading to Lollipop and flashed the AT&T baseband on this TMobile version. The result is a hard bricked device which does not even seem to power on. Shows no signs of life, except when connected to a windows pc. It shows up as 'LG Androidnet USB modem' in the device manager. No boot logo, recovery, or download mode. Fortunately she has IMEI and twrp backups for this phone (boot, efs1, efs2, radio, rpm, tz). I did some research on JTag solutions. Unfortunately, none of the boxes support the D851, yet.
Any ideas on how to recover this device would be greatly appreciated.

I'm in a bit of a pickle...
Phone is dead, I'm unable to wake it using any method, however PC sees the device being connected. I have tried to restore TWRP backup which was completed correctly but then phone stuck and failed to wake up again. I have tried to unbrick it using the LG flash tool and dll +tot files however this method fails each time -with factory model check error - and download fail notification. Right now im waiting for kdz file to download (im using the tool checking my imei to select correct one) but it takes ages with my internet.
Anyone has any ideas? Am i doomed?
Hi
Happened to me also. I got out of it by using LG flash tool and clicking on options and selecting restore recovery. It puts it back to stock and you then need to reroot etc.

Device acts dead - only visible on my pc (serial port LGE)
PID and IMEI not available to read using LG flash tool 2014
Tried
Loading KDZ file - connection failed
using tot and dll with flash tool - Failed to connect to device
Read something about laf.img using adb... Anyone has any other ideas? Funny enough when I was searching forums I was not able to find more info about cases when device is not waking up at all. but now i see few very similar threads around? Possible flaw somewhere?

It might be the PC (work pc at the moment and some IT limitations on it) however drivers installed ok, software confirms that I have latest software on my device - when phone is connected to the pc. After running Recovery Upgreade, it gets problem with comunication between the pc and mobile. in troubleshooting asks to power on the mobile (which I cannot do) before retrying. Also I have installed LG usb driver from outside as options coming with this software seem to be for really old models?
A thing I tried with another G3 was to connect the phone to the PC without the battery and then insert the battery, disconnect from phone and then remove battery again then insert and hold volume up and connect the USB to the phone again and it went into download mode and allowed the use of LG support tool as before.
Its worth a try!!

No dice... so far. I'm back home in 2 days when i can try all of this again making sure that PC is not restricted from any functionality... although it does sucks to not to have a phone until then. If you get any ideas I'm happy to try it as well.. as not like i have anything to lose at this point.
Without checking the forums I went ahead and clicked on the Wireless Update on the P8000 and now it just hangs on the Elephone logo and is not recognized when I try to connect to the PC. Has anyone else done this and has the same problem, any way of fixing?
UPDATE: Decided to mess around with the phone to try and get back to life, found an old laptop, loaded the Drivers (without any security warnings), loaded the SP Flash Tool. Connnected the phone to the laptop, did not register, downloaded the ROM 150907, went to Flash Tool clicked on scatter.txt file, pressed the power button on the phone and somehow connection was made to the phone. Bottom line is that it kicked into life with the new 150907 software, from a non techie, I am well chuffed, certainly will not be doing a Wireless update anytime soon. The new ROM is a lot more stable and even allows me to use my Works email on the Exchange services account where I had previous issues.
I have the same problem. The OTA update got my phone stuck in the Elephone boot animation. I am using Windows 10 currently and I can't install the drivers. What OS did the computer you used run?
UPDATE: I did it!! I used this guide ( http://www.howtogeek.com/167723/how...8.1-so-that-you-can-install-unsigned-drivers/ ) to allow me to install the drivers in Windows 10, and then used the flashtool. It took me some tries to get the flashtool to recognized the device but it did it.
Unfortunately all data was wiped

Which sp flash tool version are you folks running?
For me, with version .520 and .532, the flashtool stops responding as soon as the phone is connected.
Also, does the phone need to be switched off for it to be recognised? Or does it need to start booting after a shutdown?
One more, initiate "download to phone" from flashtool and then connect phone or vice versa?

The zip I downloaded is this: "SP_Flash_Tool_exe_Windows_v5.1520.00.000"
Yes it has to be switched off first and then to be connected. As for the last question I don't remember exactly because I tried many times in different ways and I don't remember which worked in the end.

The problem with this one was phone never stayed off. It would just keep switching on and getting stuck at boot screen.
I managed to fix it. Used 532 SP tool. Used an XP computer with anti virus turned off. To keep the phone shut down, I let it run out of juice (took a loooooooong time, not looking forward to doing this again), and then used an older usb cable to just get the phone to stay alive on usb current. Once you get the vcom loader message for mt65xx for usb recognition, that's when you're good to go.

There is an easy trick to turn phone off. Reboot to recovery . (in stock there is the red android then press and hold power , press vol up and it will Boot into stock recovery)
Browse to "turn phone off."
Then its off and dont reboot, you can use the flashtool....etc

Everything went fine. I was able to boot under LineageOS reinstall my apps etc, etc.
This morning when I woke up everything seemed normal too. But, few minutes ago, I sent an SMS via Google Messages the phone froze and then black screen.
When it froze I had 97% battery.
Ï tried to reboot it with power button -> Nothing.
I tried to remove the battery put it back on and pressed the power button -> One tiny vibration but nothing
I tried several times the same last process and finally I managed to get the screen with "Bootloader state : Unlocked !", but I cannot go further.
If I connect the phone with a USB cable, wether he's "turned on" or turned off no led is blinking.
Does someone have a clue to fix this or has ever encountered this issue ?
Tanks in advance and do not hesitate to refer to an old post. I wil check (but found no same case).

Just to perfectly understand.
Are you advising me to flash my recovery with an older version via my laptop (I imagine via adb/fastboot) despite I can't even get my LG be recognized by my laptop ?
Will the adb/fastboot command be functional as the LG seems not to be recognized on the PC?

The best way to get your laptop I recognize your phone is to get LG up running then with the usb plugged n drop the battery out then put battery back in then close off LG up.
Then start it again and when it go's into download mode the pull usb and close off LG up Then plug it back in with dos prompt open............

Thanks for your reply and your time. I didn't know this software "LG Up", I will give it a try this evening (in France ^^') and give you feedback then.

LG UP had no effect on the phone.
However, now the phone seems to have 0% battery and when I try to boot it I get the graphics to plug the phone on a source of energy. Once I do that the front led is blinking in orange (I guess because I had less than 1 or 2% o battery) and now the front led is still lit on in orange. Is this a good news or I'm hoping for nothing.
Anyway tomorrow I will try to get it back to my retailer.
Does anyone succedeed to get it replaced by LG even if the bootloader is unlocked ?
Thanks.
After a little journey to the repair shop of my retailer everything seems to work correctly, for the moment, with LineageOS !
Thanks everyone for your help !
