Oh did you install the drivers that are required on Windows from Asus ? Make sure you install them.
Code:
fastboot devices
will let you know if your device is connected well.

yes, i insalled driver from asus and i tried to press POWER ON and VOLUME DOWN so it change to APX mode. So, i update driver, pick driver from my computer>C:user/minh/download/usb_driver and nexus 7 still on APX mode with "ASUS Transformer prime APX interface" driver.
fastboot devices--->nothing
adb devices-->nothing

hi same thing happened to me
can you post the link of where to get the asus drivers from
any luck with your nexus yet??

Driver from Asus? Pretty sure you just use the one from the Android SDK.

thanks for that
and do you have any idea on how to get the nexus back up and running
or anyone else

Can you get in to fastboot? If so, you can flash a recovery or system imaged or anything from there. Fastboot should always work (volume up + volume down + power all at the same time)

thanks for replying
i tried many times to do various combinations o fholding down the power and up,down volume...nothing
i will try later when i am on my desktop to look at fastboot...and update the drivers
right now when i plug the nexus into the pc it comes up as not recognised...
if the nexus were completely dead would it still even come up in the device manager??
i also tried to pull the battery for a few minutes and then try again....nothing
i charge it into the mains with cable and nothing...
i will need to check it when i get home on my main pc in a few hours
please wirte any further siggestions or any web video/links which may help in this situation
THIS is the point where i turned the power off in the FIRST SCREEN
http://loewald.com/blog/?p=5198

i am on my main pc right now
i have downloaded the SDK manager and installed the Android SDK platform tools and Google USB driver
nothing happens when i plug the nexus into the PC
do i need to actually manually install these drivers or they are already installed when i ran the SDK manager...
the nexus shows as unknown device right now

Try to install WugFresh's toolkit. http://www.wugfresh.com/
Follow the driver installation guide and make sure thet the previous drivers is removed.
Choose the recomended driver.
If you can start your device in fastboot mode (bootloader) it should be salvageable.
If you use Windows 8, getting a working driver can be quite a struggle.

it was wugfresh toolkit that i was using
so i uninstalled all drivers and installed the drivers from his toolkit
sadly the usb device is still not recognised

well, i searched google and they said there was one way to fix hard brick nexus 7. It is using "JIG usb". If somebody used "JIG usb" please reply me.

I think I'm having the same problem as you, but I am still able to get into bootloader mode. It may take up to around 20 seconds holding the volume down and power button to get back into bootloader mode. In fastboot bootloader, going into recovery freezes (freezes on the "Teamwin" screen), "start" freezes on the "Google" screen with padlock unlocked. Used Wug's to try to go back to factory setting (but to 4.3 instead of 4.2.2), failed to write 'bootloader' and device never boots back up when it says "waiting for device". Then tried using Nexus 7 toolkit (not Wug's) to lock it back up and now I can't unlock again...same thing..."waiting for device" and device never boots back up.

any update for this problem?
any update for this problem?
i try alot of solution but nothing change

Look for a file v10d_downgrade.kdz in the net, you have to flash that. And the flash whatever kdz you want
It wont work with other kdz.

It does not work, the KDZ throws me the same error. Look:

DELETED sorry wrong post

First of all reinstall the drivers on your computer
Then, did you try to remove the battery, plug the phone to your computer (without the battery), then try to start the phone in Emergency Mode?
If you get to the Emergency Mode with the correct drivers installed, you should be able to flash anything from KDZ.
This method was the only way I could get my L7 in Emergency Mode AND recognized by KDZ, so you could be in the same situation as me maybe?

That method never worked for me, did you get a "UpTestEX_mod2_marwin.exe" in the packge that you downloaded? Use that, select emergency and the v10d_downgrade and flash! (follow a tutorial, you need to install small http server before...... like here)

have u tried "vol down" + "power button"
and when buttons light up, press the "menu" button
and do it a couple of times?

Nothing I've read has worked for me, trying to read the information on the device I get this:

Let pass without touching the screens and it appeared this, the touch screen does not work at this point, I touch it and nothing happens.
At a time when one of the combinations I appeared the cwm recovery, but when I restart the screen turned white and yellow of the previous photos.

Hey friend. I have already almost lost my phone several Times.
But persistance is the best to resolve your problem.
Firstly ur phone isnt bricked as it turns on!!!
So try this:
1° turn off phone
2° bottom up + down + turn on
3° should apper "emergency mode" [if this didnt work, try And get in this screen"
4°flash KDZ ( MAKE SURE ITS ON EMERGENCY MODE ON KDZ UPDATER ! AND THE MOST
IMPORTANT WHEN YOU FLASH IT WILL POP UP SEVERAL ERROS . DONT DO NOTHING LET IT CONTINUE )
5° Phone will boot loop (resolve it making a HARD RESET (bottom down+ menu+turn on)
6° now it will reset everything. Then u must flash AGAIN KDZ UPDATER (BUT NOW IT WONT SHOW ERROS ON KDZ UPDATER )
Job done
Phone recovered
PM ME IF ANY DOUBT OCCOURS
Sent From ... Lg e400 <-- {[Brasilian Here]}

Enter in DIAG MODE vol up+vol down+ turn on
(Just do it IF -> u have tried my tip ABOVE this one.)
After that , make sure u connect ur phone then, flash in KDZ UPDATE.
NO ERROR . THIS MUST WORK FOR YOU . AND AS I SAID
IF IT DONT RECONIZE YOUR PHONE THEN U MUST HARD RESET IT .
Sent From ... Lg e400 <-- {[Brasilian Here]}

Finally I could fix the problem without using KDZ and now I want to share with the community.
1. Remove the phone battery.
2. Press the button '+', and connect the usb (without battery).
3. Wait until the drivers are installed on the computer.
4. With the program of LG Mobile Support Tool, and with the phone connected press "Upgrade Error recovery" within the program.
5. Let it download the rom, you unzip and install.
Note: All this process without the battery attached to the phone.
That's all

Bootloop on CMWR and phone never close, only without battery!
Hello.
Today i want to upgrade my android, and surprise! When i push "install"and phone is was restarted, is entered in a continuos loop restart directly in CMWR mode. Here, it was impossible to install anything or make any changes, only "restart", and again, the phone is restarting directly in CMWR mode. At first I thought I bricked my phone, because even in emergency mode it could not start
BUT all this is madeit with battery inside!
After reading what was written here, I realized that I have to remove the battery, and surprise, on the second attempt i managed to start in emergency mode! (with usb cable connected to PC! ) :laugh:
Good...
Now, i openet the "LG Mobile Support Tool" (with usb connected to PC), and after LG mobile tool i let to check and install the last version of USB drivers , it was able to communicate with my PC. After that, i installed the latest available version of Android, via LG Mobile Tool and now is working.
BUT i lost the root of the phone. Anyway, it's the phone of my wife, and she's not interested in "walked" through it
Thanks to "andersonlima" , i understand that as long as boots, is not bricked !
Good luck in the future, and most importantly, read well, with calmness, that can occur various ideas, along with what you have in face, may lead to solving your problem! :good:

Its not windows 8 that is giving problms mate. It is that our phone's bootloader drivers aren't workinng. And this is best place to search for our device.

Already tried those methods of installing drivers in Win 8.1 x64, nothing works. Adb works fine, but fastboot drivers doesn't get installed and we still see those unknown E7 devices as mentioned above. If someone else have all drivers installed, kindly share us the method to install all drivers properly. Another reason to hate this driver enforcement crap!

Can you share the bootloader drivers you are trying to install via inf files? I can try it on my system. I've already enabled test mode on my system and disabled driver enforcement checks.

the official drivers from

contains bootloader drivers. if you install these via inf and able to fastboot let me know

Fastboot Drivers
Did anyone figure out how to get fastboot working? I am having the same issue. ADB works fine when the phone is off (battery charging logo on the screen) but when I go into fastboot mode (the red gionee logo displayed) the phone is not recognized by ADB or FASTBOOT commands.

^^ That issue can't be resolved under Windows 8.1 64 bit, I tried almost everything but vain. Only way it can work is to install Win XP 32 bit, and then try with the drivers posted above. It should work hopefully. Problem is my SSD is quite low on space so I won't be able to dual boot XP. If anyone else can try this on XP, let us know.

can you boot into fastboot mode by vol down + power (flashing gionee logo). if yes then it would be easy to unbrick your phone. i will post whole unbrick guide as soon as i unbrick my phone.

You people need to install the E7 Flash tools posted in development thread on your XP. Then use that to flash back the Gionee stock firmware to your phone.

When I press the vol down + power button, it turns the phone off if it is ON. When I press vol down + power when the phone is OFF, it just shows a RED Gionee Logo (no flashing logo). when I run adb reboot-bootloader, it also goes to this red Gionee logo screen and stays there. I assumed this was the fastboot mode. When the red gionee logo shows, my PC does not recognize the phone at all. Pressing Vol up + power loads the Android System Recovery (3e)

LG G2 D802 stuck on gray lines

So when you turn it on your phone after turning off you don't see the LG screen but only the lines? or only in the recovery?

Try entering download mode - poweroff the device -> hold volume up and connect to pc. Then try flashing your stock firmware.

Just tried that - it switched the phone on - the lines moved around again then settled into the screenshot.
Do I need the drivers installed on a PC for this to work? I tried it on a mac with Android File Transfer.

Unfortunately I can't get to the dialer to get my IMEI. I know they used to be under the battery but thats obviously a no no on the g2.
Regardless, I found the .kdz here http://storagecow.eu/index.php?dir=Xda/LG+G2/Stock/Hong+Kong+D802/
Installed the drivers, LG Flash Tool 2014, attempted to put my phone into Download mode (The phone has the grey lines in different places) but the PC still doesn't recognize the phoen when I plug it in and the flash tool cannot read the phone also.
Any other suggestions please? Thanks.

You may also try the tot method.
Can you recognize if the image behind the lines is small (centered on the screen) or a larger one ?
Because it might be that you've got blue circles, which are shown prior to entering the actual download mode..

I don't actually know if its going into download mode or not. I've taken another photo as below which shows what my phone looks like when plugged in, the lines move around like an animation to start of with then settle in this position - there isn't actually anything behind the lines. It's almost as if the screen is messed up and the pictures aren't displaying correctly. I seriously doubt it is a hardware issue as it was working just fine before using AutoRec.
Just so annoyed at myself for doing this so soon after I got it -_-

1. power off
2. hold volume up and connect to pc
3. flash kdz

or just connect to pc if it doesn't boot, see if there is some device in device manager that wasn't there.

To make things more clear, I've posted a video of going into download mode and showing the flash tool. Maybe this will help?

Did you install the drivers or not ?
I'll send you few links later, please remind me one more time via inbox.

Iam facing the exact same issue right now
Phone was already soft bricked. user to get stuck at the lg logo and download modestopped working , volume + power would bring fast boot so i used adb command prompt and flashed boot,aboot and recovery files and then did a reboot and all i have are these moving gray lines
IF anybody resolved this issue please help with the steps

I have a same problem. Please help me, please !

Where did you buy the phone? Some online sellers combine parts from all variants and sell refurbished phones under D802 so when you flash it bricks your phone.
Do you have IMEI on box?

But flash tools fail to connect device. please help me to solve this. I am a Sri Lanka. If you a place to repair my phone. Please advise.
Thank You.

Same thing happened with me when i use autorec, lines on the screen but the phone work normally, receive calls and messages, the touch works normally, every thing work normal but there's no screen output or colors only gray lines wuth black screen. I think it's a refurbished phone with a different board that written on the cover, and we use the wrong autorec according to the board.

To develop together...
What you'll need:
LG Bridge (Install as normal app)
Device as normally :l
Windows Using PC (I'm not sure if it works under Windows 7)
*Device drivers.
*Device drivers= Find right drivers for your phone. Download it from official LG website. How?

Should work cause it flashes whole partitions, as you can see the which partitions in attachment.
And be sure you're doing all the steps for your device model.

LG K428

Used King Root last night on my wife's K10, everything worked... gained root access no problem. Woke up this morning to a boot-loop. Found your thread and figured I would update error recovery but I can't get LG Bridge to connect. I've already installed the drivers and rebooted both the device and the PC (windows 10). The device is in download mode and the PC recognizes the connection, but LG Bridge will not connect. Any thoughts?

LG Bridge
Cannot get K10 to connect to LG Bridge. All drivers were downloaded, the computer signals that it sees a device connected, LG Bridge will start to connect when I plug in the USB cable. They I fails to recognize the device each time.

Can you paste a screen shot from devices screen when it's connected to PC in download mode? (Win+X and then select "Device Manager")

Not sure how I would take a screen shot while in download mode. I do not see my device in device manager.

I've tried Fastboot and LG Flash Tool as well to try any clear cache or factory reset. I think the issue is USB debugging may not be enabled. Would that keep LG Bridge from working?

You got me wrong. I mean, I want a screenshot from your computer's screen. In download mode, it doesn't matter has debugging been enabled or disabled.

I'm able to access the device with Fastboot. LG Bridge tries to connect when I plug in the USB cable but is unable to. I tried on 2 seperate PC's. One with Windows 7 and one with Windows 10, same result.

This reply can help you but I'm not sure how can you boot into fastboot by buttons.

Pretty sure it was volume down when USB was plugged in. Honestly I was surprised when the Fastboot screen appeared on the device. Then I figured I could try wiping data and cashe with Fastboot but it would not allow me to.
