Bricked nexus 7 please read!

Hi,
I. Have gotten myself into quit a frustrating situation. My nexus 7 was unlocked, rooted and had several different custom roms installed at various times and had never had a problem. But then one time in particular, when trying to flash a rom (which I can't even remember which one it was,) after the rom had "successfully" been flashed, it rebooted to the splash screen, which it stayed at for a very long time; before just turning into a series of flashing vertical lines that never end. I can use the power+vol- method to get to fastboot, but not recovery; it would appear that my recovery has been wiped as I get the same google splash screen loop as when I try to boot. My problem is that nothing I do allows me to successfully connect the device to my pc (w7, 32bit.)
I have uninstalled any conflicting drivers, un/re-installed the proper drivers from like 7 different guides, I have also tried two different nexus root toolkits. I even tried to use a Linux machine to no avail. I have switched USB cables, everything I have tried has not worked. This is by no means my first foray into android devices, I even freshly installed my android SDK and still my computer just fails to recognize the nexus 7 in fastboot mode.
Any tips or advice would be a godsend. Thanks.

This sounds like a issue a few people have been having.. As far as i know as of a week ago there is no solution . You need to flash the boot-loader it sounds like. There is a thread about this. Search for NV FLASH .. OR APX MODE. Sorry for being lazy and not looking for the thread for you..
They may have some things in that thread that you have not tried.

Turn your Nexus off and plug it into your computer. Does your Nexus start charging? A completely bricked Nexus wouldn't charge. If it starts charging, then try turning it on into Fastboot mode.
Sorry, I'm no dev. Just a random thought to try. But if your Nexus can charge you shouldn't be fully bricked, hopefully. At least this is what I think.

When you say your computer fails to recognise the device...
If you open your device manager in Windows and then plug in the nexus 7 in fastboot mode, what happens? Does it show up in the device manager in any category? Even with a yellow exclamation mark or as unknown device?

My bro bricked his N7
He was rooted and unlocked, flashed a rom now it bootloops on the logo. Now when doing adb devices, it doesnt detect the device when in bootloader, went to device manager and shows problem with driver. Tried other drivers but says its up to date. Thing is I just upgared his friends N7 with the same drivers so I know thats not a problem.
It wont go into recovery either. Now when it is bootlooping, the decive is recognised when doing adb devices. So can I flash a factory image when it is bootlooping or does it have to be in fastboot?

TRY THIS
from powered down,
hold VOL- and POWER for ten seconds,. then let go of POWER and still hold down VOL-

Just goes to bootloader?
Edit seems to be working now even though when doing adb devices in fastboot it doesnt list the device id

In fatboot mode you don't have adb access - down load a recovery image and name recovery.img
Hold shift and right click in the folder recovery.img is in
Choose open command here, in cmd type
fastboot devices
If you see your serial number proceed
fastboot flash recovery recovery.img
When finished reboot to recovery and flash rom of choice
ps, you have had to either change your path in enviromental variables to include platform-tools from the sdk or have both fastboot.exe and recovery.img in the same folder that cmd is pointed to

HELP! Can't get fastboot to recognize device

Plugged in device. Drivers loaded. Turned off tablet. Restarted into bootloader (both volume buttons held, hold power until vibrate)
In cmd prompt, navigate to folder with fastboot.
typed "fastboot devices" (without quotes) and it returned nothing. Shouldn't it return the device ID or something?
All I want is to unlock my bootloader and root the device!
No search has helped me. Hopefully someone hear can!

Are you sure the ADB driver was installed for the device? Try reading through this:
http://trevorsullivan.net/2012/07/03/forcibly-installing-the-android-usb-driver-in-windows-7/

couple things to try
As silly as it sounds with modern computers, but make sure you are plugging into the back of your PC rather than a a usb port on the front.
Also, even if fastboot devices comes back blank, try typing the fastboot oem unlock anyways. 9/10 times my computer comes up empty when I query for the device but then am able to flash recovery, unlock etc with no prob

As mentioned in the above post... I've had a handful of devices that won't return a fastboot id, however they except commands just fine.

Thank you to everyone for your help.
First thing I did was force the driver. It was showing up under mobile devices as Nexus 10, but I pushed the Google USB drivers anyway
This didnt help show the device ID when using fastboot devices, but I followed the above instructions anyway and it unlocked.
It's now at the X boot screen and taking a while. I hope I'm not in a boot loop. I dont know why I would be as all I did was unlock the bootloader and going to give it another minute before I reboot.

OK. It did boot loop. To fix this, follow this video to do a factory reset:
http://youtu.be/T1Se7Hr9Cww

I had the same issue as you with my Galaxy Nexus recently, and force installing the USB drivers does the trick every time. I think it has to do with Windows seeing the device as a media device (external MP3 player, or similar), rather than as an ADB interface. That's why you have to tell it to forcefully install the ADB driver, so it can talk ADB, rather than treating it as a media device.
Glad you got it working. Cheers

OKay I cannot for the life of me get this to work at all. I have never had a problem unlocking an HTC device, but anytime it comes to a samsung it doesn't work. I've tried the steps listed here, I've watched a video guide on unlocking from another post, I have the SDK updated, it sees the device as Android Bootloader Interface in Device Manager, I've rebooted straight to bootloader on the tablet, I've tried two different USB ports in the rear, fastboot will not read this device or give it commands at all. No reboot, no unlock, nothing. I'm seriously starting to freak out here. Been at this for 2 and a half hours now.

I'm sure you did this right, but let's walk through the steps again anyway...
1) turn on tab and plug into USB do windows can install drivers
2) force ADB drivers according to link at the beginning of this thread
( it wouldn't hurt to reboot windows between steps 2 and 3)
3) shutdown tab and lead into boot loader
- do this by holding down all buttons while tab is off. When it vibrates, let go of power button until boot loader comes up
4) make sure USB is connected to back of PC and to tab
5) open terminal by going into start menu and typing CMD
6) change directory to location of fastboot
7)type fastboot devices
8) if ID comes up, you're home free. If nothing comes up, try step 9 anyway
9) type fastboot OEM unlock
10) follow instructions on tab screen
Let us know if any step failed.

I've done every one of those steps to the T. Rebooted multiple times, tried different USB cables, tried every port in the back, plus both up front just for extra measure. USB port works on the tab because I'm transferring media files to it right now, it recognizes as an ADB device, drivers were also force installed from SDK Toolkit, but it won't take commands, not reboot, not ID, and certainly not unlock. The only other thing I can try is using my fiance's laptop and see if for some reason it's just an issue with my PC, because if not then it's an issue with the tablet, for whatever reason, and not being able to root this is not an option for me.

If you'd like, I can remote into your computer and walk through it with you to see if I can help in anyway. Let me know.
I will PM you my phone number so you can text me if you want to try this.

I am presently having the EXACT same problem. I have a Mac mini (mountain lion) and Windows 8 (vmware). Under osx I follow all the steps and similarly I can't get fastboot to give me the ID or recognize the unlock command. In Windows it recognizes the tablet when it's booted up normally. But with fastboot in the cmd prompt I get the exact same results as in osx.
P.s. I also had the same issue with my Samsung galaxy 3. Wound up having to root it at a friend's house.

Download and install the Android SDK. Use the fastboot tool that is inside of the Android SDK/platform-tools/ folder. I can almost guarantee success.

My win 7 didn't recognize my n10 fastboot too, so I went into device manager and updated the android 1.0 or something by selecting the main SDK folder in the android SDK as an update source
Same for adb

[Q] Cant access bootloader

Hi,
I ran into a problem with my Nexus 4, the plan was to unlock the bootloader using my mac and fastboot. (used this as information but didn't follow it step by step, youtube.com/watch?v=fHZJ2f6JLw0)
I turned off the phone and went into the bootloader with volume down + power button. From here i used "fastboot devices" to secure that i was able to communicate with the phone. My device showed up together with an error message saying "ERROR: could not get pipe properties nexus 4".
Before doing any more i wanted to understand what this message meant so I searched the web without any success. I booted up my android, turned on usb debugging and used "adb devices". This time only my devices showed up and no error messages. I used the "adb reboot boatloader" to access the bootloader once again.
I still had the same error message with "flashboot devices" as before.
From here i didn't do anything more, I may have disconnected the usb from the computer while the terminal window was open and the phone in bootloader but without running any command from fastboot.
So I didn't run "fastboot oem unlock" or anything else.
I turned off the phone and tried to access the bootloader one more time with the volume down + power button. It didn't respond to this any more and nothing happened, the device just stayed turn off.
I turned on the phone and tried to use adb to access the bootloader but now when running the "adb devices" it just responds "-bash: adb: command not found".
I have tried to restore the phone thru the android setting meny without any success. The phone is working fine without any problem except i cant access the bootloader or use adb.
So I desperately need help from you guys. :crying:
Have any of you heard of this problem before?
Regards Rasmus

I have to change my statement.
Actually I succeeded rooting and installing CWM recovery using a win7 computer together with Nexus4 toolkit.
The issue i have right now is that i can't start the device into bootloader using volume and power buttons.
To access bootloader i have to go thru the toolkit and this can be an issue in case i flash a bad rom or kernel and can access android usb debugging.
Is it possible to restore the bootloader?

Are you holding the down volume and pressing the power button?

What OS is the computer that you are using? If you have reset the device, make sure that USB debugging is checked again. I know it sounds dumb, but a lot of times it's the simplest things we forget. Once you factory reset your device, it resets everything.
If you are on Windows 7, make sure you are starting the command prompt from the same location your adb is installed. If you are on Ubuntu or another Linux distro, please let me know which one. This seems like it should be an easy fix for you, but a little more info is needed. Thanks!

adb working with device booted, but not in bootloader

adb works fine when the devices is powered on, but once I reboot into the bootloader, it no longer recognizes the device. I am trying to sideload an OTA
I have tried to update to the latest USB drivers, but in Windows 10 I constantly get the error message "The folder you specified doesn't contain a compatible software driver for your device. If the folder contains a driver, make sure it is designed to work with Windows for x64-based systems".
Any advice?

Well... You can't use ADB in bootloader. Only fastboot commands work here.
While in bootloader, use volume up/down till you see "recovery mode". Press power button and you'll reboot to recovery.
Check this guide to sideload the ota:
https://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928
2nd post...

Sorry I should say it also does not work on the prompt where I am supposed to type in the sideload command. I get a no devices found error.
Again it works fine when the phone is booted into the OS.

When entering recovery, are you sure you pressed power button + tapped volume up to see the recovery menu? And from there scrolled down and selected: apply update from ADB? Only from here your phone will be recognized...
Well, if you already did it, i'm not sure how the phone would not be recognized if it does when powered up... Maybe someone else already encountered the issue...

Yes this is in fact what I am doing. I receive a device not found error, even though adb works with the device booted into the OS.
In fact, I can do:
adb reboot recovery
Then when recovery comes up:
adb devices
and list of devices attached is blank

I figured this out. I had to unplug and plug back in the phone once I got to the sideload step.

I had this exact issue with Nvidia shield TV. I had old or corrupt adb/fastboot. I redownloaded and set up my environment from scratch, adb worked and fastboot worked

Windows 10 won't Recognize my Phone in Fastboot Mode but ADB Is working

Hey Guys,
i tried to Root my Moto E4 but Unfortunally i cant get Fastboot to work under Windows 10 Home 64 Bit on Both my Notebook and my PC. I installed The Motorola Device Manager (Since it comes with drivers) and installed ADB and Fastboot but once i Reboot into Fastboot Mode it wont Recognize it for flashing. The CMD Just Says Waiting for Device. I have expierience with Rooting other Phones but i never had this much Trouble getting Fastboot to work properly. Would be awesome if u could show me a Solution to this since i really want a Custom Rom.

There's no trick, it just works. I have Windows 10 64 bit as well and no issues. Maybe you need to update your platform tools (adb and fastboot). Using old ones can be a problem.
What command are you issuing? Just fastboot devices ?
Make sure you're not using a USB 3.0 port on your computer.

Few other thoughts:
- try a different cable; a cable that works for charging and adb communication may not work with fastboot
- avoid external hubs if possible
- be sure to reboot both devices after switching drivers if communication isn't immediately established

When you say you booted to fastboot what do you mean ?
Did use adb and your phone was recognized and then you issued adb command or what method are you using ....
You need to ensure you establish USB debugging connection first & grant authorization ...once link with authorization has been established run adb ...from adb check if recognized run command to boot to fastboot
So start from the top && go down
ARE YOU CERTAIN YOU USED CORRECT METHOD TO TURN OFF DRIVER VERIFICATION ON WINDOWS 10 && YOUR DRIVER ACTUALLY INSTALLED
Last noteworthy point ... when unlocking my motoE4 I had to boot to bootloader ONLY to use fastboot NOT "FASTBOOT"
Hold power + volume button

Excellent troubleshooting from our community. OP has not come back yet to confirm, ask another question, or simply a thanks. (Maybe he got it) Hopefully he gets it sorted.
Maybe the junior members underestimate just how quick and helpful our little community can be.

@Marc_Xperia Do not forget to install AndroidBootloaderInterface Driver Software. *android_winusb.inf*

Thats what my Problem is. I installed the Latest Android Studio, i have gone to SDK Manager. Installed the Android 7.1 Files and USB Drivers and this happens everytime i want to unlock my BL. And yes i disabled Driver Signing on Windows 10. I call it Fastboot Mode since im Used to Xperias so im Sorry i confused anyone.

When you authorize your adb connection do you tick or select always allow connections from this device ...the fact that your device is listed as *unauthorised* is a clear indication in your previous attempts you didn't authorize to "allways allow connections" from this device

Why select meta mode ? When you are in bootloader you use your volume keys to navigate between meta, recovery& factory reset & meta and you use your power key to select different modes ...what do you want to do in meta mode ?
When you are in bootloader you are essentially in fastboot mode too so it isn't necessary to choose any of the other options unless you are trying to get into recovery which is pointless if you haven't flashed custom recovery yet ..

I Succeded. I Booted into Bootloader with ADB and took a look at Device Manager to install the Driver Properly.
i followed this guide https://forum.xda-developers.com/moto-e4/how-to/guide-unlock-moto-e4-bootloader-unique-t3654275.
