Nexus 7 Bricked??/Broken

Nexus 7 was rooted,unlocked bootloader and was running paranoid anroid 3.90+ i think . i plugged it into the computer to get a new rom using nexus root toolkit v1.7.2. i was asked to update a few things, so i clicked yes. i then tried to flash stock + unroot and chose 4.3 cause i wanted to try the new OS. but i guess something happened because when i turned my nexus 7 back on i was stuck on the load screen (GOOGLE image with a unlocked lock) i could cycle thru a few options using volume keys (start,recovery,power off) .all of them seemed useless as they would just bring me back to where i was.when clicking start "booting failed" come up on the upper left side. when trying to flash stock +unroot using NRT i get up to the sending "bootloader" part and my nexus 7 just freezes, how do i fix this. please and thanks

download the factory image from the google factory image and extract the archive.
try flashing the bootloader manualy with fastboot.
locate your fastboot binary and copy the bootloader image to that directory.
open a commandline in that directory and type
fastboot flash bootloader name-of-bootloader.img
after that you can try to flash the whole factory image with the flash-all.sh script.

Simple

Boot failed??? That's a bad flash of the stock ROM. I had the same problem at my first attempt trying to flash Stock ROM, but don't worry! Let's do this:
WARNING: Before you continue you are accepting that I'm not responsible of anything can happen to your Nexus and your battery is fully charged.
When you download the stock ROM you have to uncompress the zip file. You will find the bootloader and another zip.
Uncompress that zip file, put fastboot program, the bootloader and the files together.
Then start your Nexus into bootloader mode, connect it to your PC, open a console (cmd for Windows, Terminal for Linux and Mac OS X) and type this:
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
WARNING: Your Nexus is FULLY EMPTY!!! Don't reboot it because it can get a full brick (It will not turn on any more).
Now type this:
fastboot flash bootloader bootloader-grouper-X.XX.img
NOTE: Replace X.XX with your version.
Now type:
fastboot reboot-bootloader
Your Nexus will reboot.
Type this:
fastboot flash boot boot.img
fastboot flash cache cache.img
fastboot flash recovery recovery.img
fastboot flash system system.img #Will take a very long time. DON'T INTERRUPT THE PROCESS!!!!!
fastboot flash userdata userdata.img
Now reboot again with:
fastboot reboot-bootloader
Re-unlock bootloader to get a full wipe:
fastboot oem lock
Reboot again:
fastboot reboot-bootloader
And then unlock the bootloader:
fastboot oem unlock
Press "Yes" to the petition screen and reboot:
fastboot reboot
Ready the Nexus!
I had the same problem and I did this.
I hope I can help you.
Sorry for my bad English. I'm from Argentina and I'm learning.
Well,
Good luck!

what do i type into cmd inorder to be able to type
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
and get it to work. im a noob . thanks in advance

You have to be in the folder with fastboot inside else those commands will not work.
It will be easier if you put the images extracted from the zip into the zip together with the fastboot program.
If you don't understand yet I'll try to be more specific.

It can be intimidating... and the so-called tool-kits don't help you learn
I assume you are using Windows.
follow the unzip instructions from the previous poster. (not quoted here). note the directory.
find the directory containing your android tools... ADB.exe and FASTBOOT.exe.
transfer your unzipped files to this directory. Open your CMD prompt window and change to this directory if necessary.
plug in your Nexus.
type fastboot device at the prompt. MAKE SURE YOUR NEXUS 7 is listed (serial number)
proceed with the complete instructions from the previous poster.
that should do it.

YES!!!
thanks alot for the instructions, it worked!!! i hope people use ur instructions as reference if they have the same problem. THANKS ALOT!!!

Hello. My brother's Nex 7 is also has this issue. I cannot follow any of the steps as it gets stuck on erasing any of the partitions. I tried erasing those partitions in any order and they still get stuck. His device was stock and bootloader locked too. When I try to unlock the bootloader, it gets stuck as well at the erasing userdata part. I suspect a bad memory chip. Anyone else experience this?

Yes, mine is sticking on the (bootloader) erasing userdata on bootloader unlock as well.
It also sticks on any fastboot ERASE command.
Factory reset had a bunch of errors and no longer comes up. none of the FLASH commands work because the BOOTLOADER is locked.
And since it freezes on the unlocking bootloader commands I believe I am screwed.
This was a factory installed, never flashed, unlocked or rooted Nexus 7 wifi 2nd gen. After installing the 4.4.2 that popped up it loaded once then crashed and never loaded again
I have tried every tool I can find. They all stick on the erase part.

Send your device for repair. My brother did so. My suspicions were correct. A faulty chip. They replaced the whole board, according to my brother.

nexus 7 bricked! need help

so i tried flashing the 4.3 stock image i downloaded from the google website for the grouper. i had already bricked this tablet before by accidentally unplugging it while it was flashing the boot loader. I just paid 30 dollars and received a new motherboard from eBay last week, and started playing with my nexus 7 again. This time, I made sure to not touch the boot loader as I noticed that the bootlaoder on my grouper and the one in the image archive were both 4.23. So first I issued the commands
Code:
fastboot oem unlock
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
i went ahead by issuing the command
Code:
fastboot -w update image-nakasi-jwr66y.zip
it started flashing, but my annoying brother came in and closed the screen of my macbook. When I opened it again, the fast boot mode was still showing on my nexus, but the flashing on terminal had stopped. i quit terminal and opened it again. i typed:
Code:
fastboot devices
and my tablet showed up as normal. However, when I tried to issue any command, terminal would just display a blank space. I then selected reboot boot loader on my nexus, but the device just turned into a black screen, exactly the way it appeared last time i bricked it. I'm so frustrated and confused. Why is the device refusing to go into the boot loader using power-volume down if I didn't even touch the boot loader? At the most my device should only be soft bricked. I checked the contents of image-nakasi-jwr66y.zip and the contents were
Code:
android-info.txt
boot.img
recovery.img
system.img
userdata.img
I don't think these have anything to do with the boot loader?
the flash log didn't show any evidence of touching the bootloader except the check part where it checked the boot loader version, which was reported as 4.23.
If someone could provide me with assistance it would be greatly appreciated!

Tried restoring to Stock/Unrooted and now stuck in Bootloop - Please help

Ok I messed up pretty bad this time.
I used my Moto X Pure 2015 for a couple months. Unlocked bootloader, rooted it and used a couple diff ROMs. My father liked the phone, so wanted to give it to him after restoring it to stock, meaning unroot, lock bootloader, restore to factory ROM. But somewhere along the way I messed up and dont know how. I may have tried to flash 5.1.1 when my phone was already updated OTA to 6.0 but I am not sure.
Now I am stuck in a bootloop. The Moto Android logo comes up and it keeps looping there. I can enter bootloader but cannot enter recovery. It goes back to the loop when I attempt to go to recovery mode. I tried flashing (with the Flash-All.bat) packages lying out there, but my device isnt recognized. It says device not found. I cant even restart bootloader through the adb command. I type adb devices in cmd and it says ADB devices attached, but I dont see my device displayed. But Device Manager lists my phone as Motorola ADB Device.
I took a chance and sent it to Motorola......................... surprise surprise...../s , they refused to fix it coz of the unlocked bootloader(even with a fee).
So, now I cant flash anything, I cant go to recovery, nor can get the phone to boot up.
Have I lost the device completely? I dont have any nandroid backups either.
Any help is greatly appreciated.

Ok. I made some progress. I Uninstalled my device drivers, reinstalled from the Motorola website. I am able to flash things from fastboot.
I did the following for MM6.0
adb reboot-bootloader
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot flash bluetooth BTFM.bin
fastboot erase cache
fastboot erase userdata
fastboot reboot
Everything was successful.
Now I can boot into the OS.
But now my WIFI isnt working. I go to settings and try to turn it on, but it doesnt.
Can someone help me here>?

are you sure you flashed everything correctly?

I don't know directions or anything, but I can tell you from other posts on the moto x pure forum that your not the first to lose wifi after restoring stock. To my knowledge you need to down grade to the original factory Android version, not just 5.1 or whatever, it HAS to be the original Android version, AND original baseband and system version, then upgrade from there. Hour that helps a bit, but do some searching and I'm sure you will find what I mean.

Thanks for your reply guys. I eventually fixed it. I now am running the TruPure ROM and everything seems to be working fine.
Except the the MicroSD card that I had 'adopted' is now write protected. I am not finding any luck trying to salvage that. I dont care about my data on it, just want it to be usable. I read somewhere that the card, once adopted, will only work on that ROM that it was originally adopted on. I even tried flashing the other ROM (OrionOS) but no go. My phone doesnt recognize the card except in Recovery. Computer recognizes it but I cant do anything since it is write protected. I tried DISKPART, the regedit fix and a bunch of other stuff. Didnt help. Its a brand new card, so I dont believe the card has gone faulty. Any idea on how to fix it?

Hello,

Please lock the bootloader." (Orange), but after researching on the internet many people said that was normal due to the boot loader being unlocked...
however my concern for today is i have flashed back to the factory images of marshmallow, and am now experiencing an error on boot up that Your device is corrupt. It can't be trusted and may not work properly." i followed the exact step-by-step guide on how to unroot and lock the boot loader on the link below however am still experiencing the issue, please help it will be ever so much appreciated.

I've had that as well with mine before. The way I fixed mine was a somewhat tedious process but it did work for me. Start by downloading one of the angler images from Google, then with 7zip, decompress the .tgz which gives you a .tar. Once more will get you a folder named xxxxxx-angler. (I think it was that way but not 100% sure since I'm not at my laptop at the moment). With your phone (unlocked) in bootloader/fastboot mode, run flash-all.bat. this gets you back to a fully stock system but still has the corruption flag tripped. Run stock recovery and do a factory reset and the corruption warning should be gone and back to the "normal" screen saying please lock the bootloader.

Try doing this process manually, if you're selling it. I would infer the data doesn't matter on the device.
Depending on which OS you are on. Focus your command prompt with fast boot installed to your directory containing the stock files (unzip the image zip)
Now do the following process manually. Step by step
fastboot flash bootloader bootloader-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash radio radio-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash vendor vendor.img
fastboot reboot-bootloader
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot format cache
fastboot flash cache cache.img
Now, if you still get the red warning. Repeat the process and add :
fastboot format userdata
DO NOT FLASH THE USERDATA IMAGE
If this does not work, I have other suggestions.

same prob in orange..plz help bro

To flash back to stock, you have to boot into bootloader and using fastboot to flash factory image.
But hey, you're in the Nexus 6P forum, try following this guide in the Nexus 5X forum:
https://forum.xda-developers.com/nexus-5x/general/guides-how-to-guides-beginners-t3206930

I just went through this. Just unlock your bootloader with the Nexus toolkit and it'll go away that's all i did

Nexus Player Rom help

Hi im having problems here with my nexus player
i purchased and used this since 3year with custom AOSP android lollirock that i found on this forum how to install in the begining when i purchased it now since there are newer version of android and app stop working correctly on it i wanna return to the stock rom
what it did is after booting into fastboot and running those command using google official rom
fastboot erase boot
fastboot erase recovery
fastboot erase system
fastboot erase cache
fastboot flash bootloader (bootloader filename)
fastboot reboot-bootloader
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash cache (there were no cache.img in the google official rom package so i leave it like this)
fastboot reboot
my nexus bootloader is in UNlocked state, i remeber unlocked it the first time i flash the original rom to install the lollirock one
the device rebooted and now im stuck in the bootloop of circle turning in the screen
i did the exact samething trying to install a older version of the rom (after i read on the internet that the 8.00 was sending people who never messed around with fastboot and just using OTA to update into this samebootloop)
i got the same exact problem using an older version of the google official rom 7.1.2 i try i think
then i tried to reinstall AOSP custom 7.1 of android that i found on the forum of zulu99 he tell to
fastboot flash boot boot.img
fastboot flash system system.img
fastboot -w (and i noticed that when i run this fastboot return me and error saying that the file is missing (cannot generate image for userdata)
anyone know what i can do from here ?
im able to get into fastboot no problem holding the button under the device before i plugged in the power cord
im pretty a beginner using ADB and flashing android roms so i have no clue what im missing here but i guess its something due to the fact that ivd run fastboot erase cache.img in the begining !?!?
Please any help would be greatly appreciated

I always used the nexus root tool kit for everything.
