I think I bricked my New Nexus 7

I'm new to the forums and I've been searching and reading all over for help. This was my first time rooting. I was trying to flash a rom in TWRP and somehow erased everything, no OS or anything. Now when I boot up it only says google. It won't load past that. I can get into the fastboot screen but the adb options don't work. And now since trying two different tool kits to flash to stock image, I can't get on TWRP anymore. Any help would be great thanks. I'm not even sure what I did but I can try to add more information. Thanks

You can boot in fastboot and flash it back to stock.
I see Google hasn't posted the factory images out there yet, your tablet is fixable, but you need the image. Maybe someone else can chime in with a image I haven't found yet. BTW, you can fastboot flash the recovery if its a .IMG file to get that back.
Note: you'll need the android SDK because you'll need the fastboot drivers and the fastboot.exe program to flash back.

Can you boot into fastboot mode by holding all three buttons for 5 seconds with the device off? It doesn't need a os or recovery just as long as you didn't kill the bootloader. Once in fastboot just flash it back to stock.
Download your image here: https://developers.google.com/android/nexus/images
Don't freak out yet, its hard to brick a nexus device
Edit, I just saw you said you can get fastboot. Use the link I posted to download your image, if you need the android SDK because you'll need the fastboot drivers and the fastboot.exe program to flash back.

Obviously ADB would not work in fastboot. Erasing your ROM and recovery is no where near being bricked. You get into bootloader by holding Power + Volume down. Google has not released the official image package yet so flash the stock images from these -

I'll try this all out in the morning. It's getting late here. Thank you and I'll be back to give you all an update!

You could even skip flashing the stock recovery and reflash TWRP. Rename it "recovery.img" put it in platform-tools... Then:
fastboot flash recovery recovery.img
TWRP should be flashed. Install a stock deodex or odex ROM and wipe data before install. Should be good.
But, everyone else's solutions will also work too (ie you are NOT bricked )

I think I'm having some problems trying to download things in the correct folders, seeing as I don't understand most of the lingo. I used a all in one tool to unlock the bootloader and root but when I tried putting things in the folder it wouldn't load properly. I deleted everything off of my pc and I'm going to redownload everything and try again.
Tried http://forum.xda-developers.com/showthread.php?t=2381582 early this morning and it wouldn't load properly. I ran it and it said ?????? fastboot and then said some files were missing. Let me get back at it though.

You're just gonna have to own up and install the SDK. It only takes a few commands once it's downloaded.

Installing the SDK isn't necessary.
All you need is fastboot.exe and the ADB files.
I really wish people would stop telling others to install the entire Android SDK, because it really is a waste of time.

+1 I didn't know somebody compiled that for the new N7. I was mostly trying to get this fellow to shy away from the toolkits - not that they're bad... But when they mess up, it's a headache to recover.
Sent from my Nexus 4 using Tapatalk 4 Beta

When I post on here I think its better to assume I'm posting to a noob rather assuming they know something they don't and making their situation more stressful. The SDK is a blanket install and you know everything is there. For someone inexperienced its better than: get this driver, and this one, and these files...move them here..you get the idea.

The guide on that thread should work really well, but I will just point out that for me, ADB wasn't working (yet) while I was still trying to flash TWRP on it, so the 'ADB reboot bootloader' line in the "Recovery_Nexus7.bat" was pointless. In my case, I go to the bootloader/fastboot mode by holding the power button + volume down.
Once in fastboot/bootloader mode, ensure that fastboot can see your N7 2013 by typing 'fastboot devices'. If you see your device there, you are good to proceed with flashing all the files that are in that zip file. It even roots your device. Good luck and let me know if you need any further help.

Are you logging in from your administrator account and is it windows 8 by any chance ?
Well, Rule is log into from your administrator account and windows 8 will need manual drivers installation for your Nexus 7 (2013). Try downloading USB drivers from SDK.
I am also attaching fastboot drivers which I hope will work
Good luck

[Q] [VK810] Stuck in Fastboot. Need Boot Image

Hi.
As the title says, I have bricked my GPad and am stuck in Fastboot mode. I am able to pull up a command line on my computer and reboot the device from there, but that's about all I've tried. I have read online that there are commands for flashing a boot.img file, but I can't find one and I don't know how to do it. Do I wipe the device from my computer first, or just flash the .img file? Any help would be greatly appreciated.
God Bless, Mark

Don't wipe the device! At least I wouldn't. Might not be able to get back in!
Flash recovery and then a ROM.

I was rooted, running 4.4.2. I tried to flash 4.2.2 aboot.img with Flashfy, so I could flash TWRP recovery. Didn't work out.
Flashing a recovery is what I don't know how to do in fastboot mode. Can you walk me through it? Also, I don't know which recovery to flash.

The directions for installing are in the link I gave you, showing to push (put) the files in the proper places for your device.
You must have ADB installed on your home computer. There is a guide on how to do this in the general section ( second sticky post), or, if using Linux, the first post.
After ADB is installed, both the Loki patch and the recovery.IMG will need to be in the platform_tools folder in the ADB folder. In Linux this would be /opt/adb/platform_tools.
In either case, to install, you must open a terminal (prompt) in the path of the install, meaning you must open the terminal in platform_tools.
Then follow the commands in the recovery post to install both Loki, and the recovery.img

Ok, I got it. Duhhh...I re-read it and it makes sense now. Somehow I had it in my mind that I had to open terminal emulator on my GPad, which I can't do. I'll try it tonight when I get home from work and let you know how it goes. Thanks again.

OK, Sleekmason, I put everything where it should be, but when I use the "adb" commands (adb push loki_flash...) I get "device not found" in terminal. As I said, I can reboot the GPad using "fastboot reboot" command, so it sees it in fastboot mode, but not in adb mode. I loaded the drivers during the adb install, so I'm pretty sure all of them are there. Is there something I'm missing? Is there a way to push the files to the GPad with fastboot?

not saying you should, but you could always try to flash the recovery just to see if it would work.

same problem, but how I fixed it
How I got bootloop'd - I was on a trip and tried to root/flash twrp from a chromebook and as you can tell the process did not work. I ended up trying to flashfly a 4.2.2 boot.img over a 4.4.2 setup. Not the best idea. Once I returned to my windows machine, I was able to flash via adb/fastboot tools. So I found this thread and wanted to help anyone else if they arrived here and read thru the posts.
I was stuck at the fastboot text base screen on my Gpad (VK810). I dl'd the LG tools, the LG driver & tried a KDZ recover, but I was unsuccessful. Fastboot would control my device, reboots worked, but when I run fastboot devices, I only saw a single ? where the device serial number is. After a few attempts at various methods, I ended up guessing which file I had to flash.
After dl'ding a few roms from here and extracting them, it took the boot.emmc.win and flash my boot.img with that. worked with the following code and now I'm up and running.
Code:
fastboot flash boot boot.emmc.win
followed by
Code:
fastboot reboot
this worked for me and could work for you, but I can only say that it worked when I was able to access my tablet via fastboot commands.

Downgrade aboot
dd if=/sdcard/aboot.img of=/dev/block/platform/msm_sdcc.1/by-name/aboot
exit
exit[/HTML]
I am not able to do the above after installing Lollipop because can't get root, specifically can't update binaries in supersu and no su. Also Adbd Insecure not working. Now I am able to get into fastboot, strangely thru factory reset. Can I use 'fastboot flash aboot aboot.img' instead. Many thanks.

[Q] Need help ASAP! CWM problem.

Hey guys, this is my first post on XDA forum.
So I've recently bought a nexus 7, I used wugfresh's root kit to root my nexus but then it didn't work... so I've tired the auto root by chainfire. Then I was able to get root. So then I went to playstore and downloaded rom manager to install CWM. I went to recovery then I get this message:
E : Cant mount /cache/recovery/log etc.....
I've tried everything I can do such as researching, changing recovery, and watching a youtube tutorial but nothing helped.
Thanks.

I would start over from scratch using fastboot to flash a factory image and stock recovery. If your bootloader isn't unlocked already, unlock it.

DO NOT USE TOOLKITS. They cause too many problems. Learn to do things the proper way using fastboot. I agree with the poster above, you should flash a factory image to start over. Download the system image from here- https://developers.google.com/android/nexus/images
You need to unlock your bootloader-
Code:
fastboot OEM unlock
Then run the flash_all.bat. That will automatically wipe and reflash everything to get you back to square one.
Then you need to flash TWRP (don't use CWM)
Code:
fastboot flash recovery recoveryname.img
TWRP will automatically prompt you to flash SU when you reboot. Choose yes, reboot, then install SuperSU from play store, update the SU binaries, reboot again, and then you're done.

No, you can only flash custom ROMs if you have a custom recovery.

Flash failing tried everything.

Hi all,
I hope someone can help as I am at my wits and sanity's end.
I am trying to install twrp into my phone to make a factory backup before rooting. I have unlocked the boot loader via htcdev all OK, I have followed the guide online to install twrp but it just will not work, I have tried various methods and every one of them failed. ADB and fastboot are installed OK, when I type "fastboot devices" it shows the phone and serial number, HTC sync is installed and updated, SDK is installed, everything the guide said to do I have done but it just won't flash. Error when I try to flash twrp every time. It is the latest version etc (I think) the twrp image is in the adb/fastboot folder and the cmd was opened from the folder.
I really don't know what I am doing wrong, can anyone please advise?
Thanks in advance

download it, connect tehphone to pc, move the rom zip to either extsd or internal sd, boot to recovery select the zip and flash.don't forget to make a backup, and to wipe dalvik cache, cache, system,and data,under advanced wipe. nothing else then install the rom
what was causing the problem before, that you couldn't get recovery to flash, just curious

tbh i actually used the m9 toolkit by Squabbi - did it in 5 minutes

ok cool, glad you got it going.

Phone always boots in TWRP

My ZE551ML is unlocked/rooted running the stock MM from asus, everything worked fine for a long time now.
This morning my phone booted in TWRP, and whatever I try, it always boot in TWRP. The only thing I know has changed is that yesterday Magisk installed an update.
How can I recover my phone? adb is working, I can go in TWRP, but what else?!?

Try wiping your misc partition:
Code:
adb shell dd if=/dev/zero of=/dev/block/by-name/misc

Problem was Magisk v11.5 that updated itself, it is not signed. I restored a previous boot backup and back in business.
So people, do not update Magisk using their builtin updater!

Hi, I have same problem. Can anyone please post an step by step to do that adb thing?? I mean, my ZF is stucked in recovery (via fastboot I installed TWRP) but I don't know how to execute that line posted before. I can only get my device as adb sideload so that line posted returns an error... please help or tell me how to find that info.
Thank you in advance!

Hey, my phone randomly stopped booting, and I can't seem to get it to work. It boots to TWRP and I have full root access, with an unlocked bootloader. Do you have any idea how to fix this? I don't know what to do with this.

You dirty flashed your rom then. Everytime you update, first wipe your system (not data!), then flash everything you need (not sure about gapps and stuff, just flash them to make sure)
