Bricked 2012 Wifi Only Nexus 7, Please Help

Sorry if this has been addressed but I've been searching and reading and freaking out because I can't find out how to recover my Nexus 7.
I'm trying to manually update my 2012 Wifi Only Nexus 7 to Lollipop and my computer will not see the device any longer in ADB.
I downloaded the latest sdk and the latest image file (Nakasi 5.0.2 (LRX22G).
Ran through the steps found here: http://www.androidcentral.com/how-manually-upgrade-your-nexus
At this step fastboot flash bootloader [bootloader file].img it just sat there for about an hour and didn't do anything.
***Edit- I got it to work and then got the invalidstate error.
I then read that others have had success updating to Lollipop without updating there bootloader here: http://android.stackexchange.com/qu...t-flash-bootloader-failed-remote-invalidstate
***This is because my bootloader was already on 4.23.***
I then proceeded with fastboot -w update [image file].zip
The image failed after wiping everything with an error about too many links.
Now when I try I get "C:\Users\John\Desktop\Nexus 7\Android\android-sdk\platform-tools>fastboot -w upd
ate image-nakasi-lrx22g.ziparchive does not contain 'boot.sig'"
At this point, I can't get any adb commands to work as the device is not showing up as a connected device. I've rebooted my pc and the tablet multiple times. Fastboot keeps crashing as well.
Please help me get my Nexus back up and running. Thanks so much.

The Bootloader in the factory image is not valid see here
If you still can get into fastboot on your device,
Extract the img files from the zip file and manually flash each of them.
Alternatively, you could extract all the .img files in the zip file and flash them manually one at a time. This makes things really handy if you're using the factory image to act as an update rather than a complete return to stock. If trying to update using the factory image, extract the .img from the zip file into the same directory as your bootloader and radio img files and execute the following commands in order:
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cache cache.img

Are you in fastboot mode?
Step 4: Make sure the device is connected to the computer while in fastboot mode. Different devices may require different commands to get into fastboot mode. Make sure the device is powered off and then use the following button commands:
Nexus 7 - Vol Down + Power

Since you issued an Adb command first, suggest your not?
Another option would be to use Wugfresh Nexus Root toolkit and set the option to "Force Flash Mode" in Options Flash Stock.

Noticed this part after I posted last, seems to be working....I'll let you know. Thanks so much. Wish I would have seen the toolkit earlier today when I started haha.

You rock corkiejp! Working like a champ now! Thanks so much.

I had exactly the same problem and ended up using Wug's toolkit and the individual images.
Sent from my Nexus 7 using XDA Free mobile app

I literally had it restore the factory image and it did it all. Made sure I had force flash checked.

Man, I really need some help here. i am in a almost exact situation here. Only thing different is that my tablet is locked. I go to wugs and flash stock image and get stuck on "waiting for device".

Hi, rayandreas...
Something is definately not quite right with your posted screenshot/output.
Transcribing it as follows, we have...
Code:

So far, so good.
I can see nothing wrong with this output, thus far... and I've seen something similar on my Nexus 7 many times when I've fastboot flashed stuff.

But then this bombshell hits!!

WTF!!!
Bootloader is now locked!
How is this even remotely possible?
----
If the bootloader is locked, the first half of your posted output simply shouldn't have been possible... But yet, your screenshot proves otherwise.
The bootloader is either locked and NO fastboot flash commands are possible, or the bootloader is unlocked and ALL fastboot flash commands are possible...
Your Nexus 7 seems to have 'changed its mind' about its bootloader lock status, halfway through fastboot flashing!!!
----
To determine the bootloader lock status of your Nexus 7, you need to boot your Nexus 7 into it's bootloader manually...
*** shut down the device completely.
*** press and hold VOL DOWN, and press POWER ON.
*** the text in the lower left hand corner of the screen should indicate the devices bootloader locked status.
See my attached screenshot for the sort of thing you should expect to see if the bootloader is unlocked.
---
If it's locked, try unlocking it manually (ie, via fastboot), with...
Code:
fastboot oem unlock
Hope this helps.

Thank you for even taking time for helping me thus far. I can say that it states the boot loader is locked. I have tried using wugs to unlock it but it doesn't work. I can't boot it up either. Just stays on the google splash screen. I am at a loss at what to do as of now. If I could get some help on how to rescue this thing I would be glad to donate a 12 pack or a 10 coffee or something. I received the tablet this way. I am hoping to fix it so my wife can use it.

Hi again, rayandreas...
If it where my tablet, I'd just fastboot flash the Google factory stock image for your device.
The Google factory stock image for your device can be found here...
https://developers.google.com/android/nexus/images#nakasi
There's little point in my re-inventing the wheel by writing yet another tutorial... full details and instructions can be found here...
[GUIDE] Flashing a Factory Image with fastboot / return to stock
----
But all of this is contingent upon successfully UNLOCKING THE BOOTLOADER.
The bootloader needs to be unlocked, before anything can be fastboot flashed.
Whilst this can be done with toolkits (such as Wugs), I personally prefer to deal with fastboot directly (instead of through a layer of GUI polished menus and dialogue boxes).
----
From power-down state, or to force boot the device into its bootloader...
** Press and hold VOL-DOWN.
** Whilst holding VOL-DOWN, press POWER ON.
** Keep BOTH buttons pressed for a good 30 seconds.
If successful, you should see a GREEN ANDROID lying on its back...
----
USB connect it to your laptop/PC. Ensure you have the correct drivers installed on your laptop/PC as per the instructions detailed in the above link.
The command is as follows...
Code:
fastboot oem unlock
Due to security considerations, this command will wipe the Nexus 7, and you will be advised of this by the Nexus 7 itself, and you'll also need to confirm the bootloader unlock request at the Nexus 7 end via a confirmation dialogue box.
(See the attached screenshot for the sort of thing you should expect to see).
If successful, you should see an unlocked padlock symbol at the bottom of the screen, underneath the Google logo, whenever the device boots.
----
Unlocking the bootloader is critical if you wish to fastboot flash anything. Even official Google factory stock images require an unlocked bootloader to be fastboot flashed. And with the Google recommendation that the bootloader is re-locked afterwards with...
Code:
fastboot oem lock
This is optional of course, and I would generally recommend against it, because if you wish to unlock the bootloader again at some future date, it will wipe/factory reset the device...
General point of advice: Once Unlocked - Leave it Unlocked.
---
Hope this helps... and good luck.
Rgrds,
Ged.

Maybe your bootloader is corrupted? @GedBlake, can you provide him with latest 4.23 bootloader? I was searching the web and found out some bootloaders can be bad. Someone correct me if I said something wrong(just trying to help xD)

According to this article, some of bootloaders were corrupted or what. Update NRT masterlists in the toolkit and try flashing the latest bootloader if that is possible through the toolkit. Maybe it will let you to unlock the bootloader afterwards. If the toolkit can't do that for you, download latest factory image(4.4.4 or 5.1, what you desire) and extract the bootloader from the image. It will probably be named "bootloader-nakasi....." Try manually flashing it through CMD/ADB using "fastboot flash bootloader "name of bootloader file". I repeat, I don't have much experience with this tablet, but I'm doing what I can. Try doing what I suggested, maybe it'll work. You can't make it worse after all Good luck!
EDIT: In the link I posted, there are some neat instructions and a link to the new bootloader down the page. Make sure to check that out too.

I did update the NRT images and tried again with no luck. I also tried going into recovery and this is what I get. So, it looks like I have a crazy locked boot loader and no recovery at all. I am trying the other method now. We shall see!
Thanks for all the help so far. It means a lot!

You actually have a recovery, a stock one. While at that screen, press Volume Up + Power for 1 sec( or only Volume Up, not sure) to access it. You can try doing a factory reset there if that helps anyhow.

- Open the Unbrick folder and run blank-flash.bat:
- Flash Stock factory images: (Problems see #2)
Your phone should show up on the computer as fastboot.Just flash stock factory images. (Motorola via "RSD Lite" or Google one should do the trick).

If you just bricked by downgrading bootloader, the persist and modem calibration should still be happily where it was when you started.
This won't help you if you're stuck with Allow OEM Unlock. Be careful locking on 5.1. There's accurate information elsewhere in the forum on that.

No IMEI / No Signal

If wifi/bt/camera dosen´t work Then probably your /persist got somehow corrupted. (Post Under construction)
For a fix:
Flash a custom recovery, and open a terminal with the phone booted to it
run
umount /persist
mkdir /persist
mount /dev/block/platform/msm_sdcc.1/by-name/persist /persist
#e2fsck /dev/block/platform/msm_sdcc.1/by-name/persist
you will be propmpted to check / repair errors, keep pressing enter for each that it appears

Oh no wait, I DIDN´T SEE THE AUTHOR LOL.
may i ask was it hard for you to get the permission to post? afaik these files are proprietary (aside from the paritition table) or aren´t they?.
also can i ask you something a bit more offtopic?
i noticied the nexus 6 works directly with QPST (at least it can communicate with it)
but some other devices (like the nexus 5) can´t, its something that qualcomm or the manufacturer decide / make?
Once again ,props to you and motorola!
Never thought of an oem doing that, even more that the bricks can only be achieved when messing with things you shouldnt be :good::good::good:

Erm, don't mind me asking one question.
How do you back up your efs if your phone is bricked?

So I thought I would rid myself of no Xposed or CM12 on 5.1 (LMY47D) by going back to 5.0.1 and flashing CM12 again from an older nightly I had downloaded already....I think we all know what happened.
I managed to get through it all and have the blank-flash boot loader screen up but I get hung up on <waiting for device> when trying to flash factory image (LMY45D). The boot loader shows as locked and as a result I am unable to flash a factory image. Hopefully I am not breaking any rules or anything by posting this here but this is the error I am getting when running the flash-all.sh:

Looks good. Does this only help the CM12 people or does it override the "enable OEM Unlock" people too?

Damn, wish this was on here last week. Had to send my N6 off to repair centre for this as I thought it was a gonner. Fault diagnosed as 'Electrical issue - Replacement required'. Replacement is coming tomorrow hopefully. Will bookmark this, thanks.

I am stuck in the bootloader, which is locked. I can't boot the phone up. I am trying to flash stock images but nothing is happening. Just booting to the bootloader every time.
I can detect my device using fastboot devices, but every time I try and write an img it fails, because the bootloader's locked! Argh!

I HAVE THE SAME ISSUE!(A2017G) SOMEONE HELP! :crying:

You're not bricked, you're just down ATM. If you can get into bootloader or EDL mode you're fine. Just gotta put some work in. First, you've probably got a bootloader that doesn't allow fastboot commands. (the reason why you're getting the unknown command error). You need to flash that via EDL if you don't want to downgrade/unlock your bootloader. There is SOOOO much to read out there that with a little searching and reading you'll be up in no time. This toolkit is a good place to start looking. https://forum.xda-developers.com/axon-7/development/tool-axon7toolkit-t3573108

Hey, I CAN use Fastboot commands. but i cant get to recovery mode even tho i flash it. my bootloader is unlocked. please help!! i am stuck

Well with the error message you posted, "unknown command" means that you're on the wrong bootloader. You have two methods to install TWRP. Bootloader or EDL. If you want to do it via bootloader you need to load the B20 bootloader and that'll allow for the fastboot flash recovery "name of img file".img command. If you're wanting to use EDL you'll need to use a tool to force the recovery image.

I get this but when i try to boot into recovery, it boots into fastboot mode. Help

Ok that means that both of you are using the G model. If you're able to get to your bootloader try using the tool that I linked above. I have the U model so I can't relate with some of your issues but I believe that if you can reach the bootloader the tool can help. Have you tried manually booting to EDL?

There is no solution so far.
Have to wait untill someone will create a flashtool for DFU mode for Snapdragon 820.

Did you search on the forum before bumping a year-old thread?
So far there are 2 DFU guides, mine is the latest. (Google "dfu unbrick"). Though you might want to try an EDL cable before doing the process on the guide. Just use MiFlash or EDL Tool along with the cable, and you might fix it.

Dang now its totally bricked after the flashing failure... cannot boot up. what should I do? send it back to Essential?

What do you mean by can't boot up? Do you see boot animation and have you tried to go back to fast boot or recovery?
Sent from my ONEPLUS 3T using Tapatalk

Try different USB ports and cables. When 8.1 came out I had to swap my cable and change the port I was using on my desktop, for some reason the cable I had been using and the port I had been using since I got the phone was no longer adequate. There were a number of other people having the same issue. Some commands would look to complete properly, but following up with the same command (something un-damaging like fastboot --set-active=a | fastboot --set-active=b) would either error again or show that the 'completed' command hadn't actually done anything. I switched cables/ports around (ended up with an Antek USB-A to USB-C cable in a USB3.1 port) and everything worked properly.
If you're trying to flash a stock build image from Essential, you will probably need critical unlocked because those images do contain a bootloader that gets flashed, and that is secured behind critical.

Do not use the cable that came with the phone!!!!!

We are screwed mate, I am on the same boat with you. Essential took no responsibility and offered a 200$ replacement device. The phone doesn't power on anymore and no light indicators are working, so hard bricked.

I had a Asoip screw up(did not disable password) and was only able to get fastboot. Had to see what slot was active and flashed to that slot that was active boot.img,twrp,Asoip and was back up and running. My bootloader was unlocked. I read through all the posts and peoples screw ups and was able to get it up and running again in a day. I never posted as I wanted to learn it on my own. Good luck.........

and pressing the volume down key + power key at the same time doesn't work?.. what happens when you plug your phone into the charger? does it vibrate?

ive had fastboot command problems previously myself with this device and found that the usb port can play a pretty large factor. Swapping usb ports and reattempting to run the commands (as others recommended may be useful) make sure you are using latest version of adb/fastboot and have up to date drivers installed for the phone.
Look at the rooting tutorial there is information in there about swapping active slots (the essential has both a and b paritions) if you set the other slot as the active slot you may be able to regain some communication within fastboot (i would suggest you verify with fastboot devices prior to attempting to flash to partitions).
Additionally you should be able to still recover back to stock without custom recovery using the default recovery partition. I would think that if you are able to access the bootloader you should be able to access the default essential recovery partition. If you can access the standard recovery you should be able to factory reset the phone and sideload a new rom (id suggest the default factory image from essential until you can get back to square one)

I'm in the same boat. Tried to flash twrp after upgrading to 8.1 and got the same Error flashing partition, and now I'm stuck on the bootloader.
I've found that if I lock/unlock and lock/unlock critical it will let me flash the stock 8.1 boot and every other partition except for system and vendor, but gives a flash write error for those. I'm still unable to get past the bootloader.
Essential basically said I'm SOL. $200 out of warranty replacement assuming I live in the US, which I don't.

Mine was doing this too, but it was only a few days old so I returned it. I'm pretty sure it's defective flash memory.

My phone was doing this exact thing. Botched factory installs rendered my phone hardbricked.
Tried a thousand+ things to get it to turn on to no avail. LUCKILY I bought it second hand and have no warranty D:

Unable to unlock bootloader on my Asus Zenfone Max Pro M1

So, I bought a new Asus Zenfone Max Pro M1 3 GB variant today. I was really excited for it to arrive. Obviously, I wanted to install custom recovery and flash magisk on it. However, now that I'm trying to unlock the bootloader, I'm getting a message saying 'Press any key to shutdown.' What might be the problem guys? I've installed all the drivers and my OS is Windows 10 64bit with an AMD Ryzen CPU.
Help would be greatly appreciated.

To flash recovery do the following.

Fastboot flash recovery ( after this command hit the space key on keyboard, then drag the .img file to the command window and hit the enter key on keyboard)

I also have 6gb variant. Try using usb 2.0 port and windows 7/ linux.
I installed linux on my old laptop (this also worked for some users) and instead of installing windows 7 (bc i know i will run into drivers issues) i installed linux mint.

Try following my guide here. If it didnt work, post your problem there and I will see what I can do
