[q] hard bricked

OK,
So a friend of mine asked me to help him fix his Nexus 7 2013 FLO (WiFi only).
According to him he hasn't even unlocked the bootloader (and the info displayed while in fastboot mode confirms this). Apparently what happened, a few months ago, he downloaded an OFFICIAL KitKat OTA, clicked OK to upgrade, and since then, the tablet will not get past the screen that says Google. I can get it into fastboot mode but cannot flash anything, and when I attempted to use The Nexus Root Toolkit by WugFresh to unlock the bootloader at the very least, I can get it to display the screen that says "please use the arrow key to navigate Yes or No. Unlocking your bootloader allows you to load a custom OS, but may void your warranty, etc. etc. etc."
I tried using CMD to erase the cache and userdata and after giving it upwards of 20 minutes, during which the window (in CMD) simply said "erasing cache" and never actually made any progress whatsoever...
Any idea what (if anything) can be done?
Sound off in the comments!
Thanks a million!

I can't help... but am in the same boat as of last night with the 5.0 update.

Were you able to unlock the bootloader? You did say that you were able to get to the screen to unlock it. If not, i dont think much of anything can be done.

Virgin N7 2013... No hacking... Bootloader locked... started acting weird and I attempted a system restore. It now gets stuck at the Google screen. Fastboot gets stuck at erasing userdata. I have tried multiple USB cables on Win7, OSX, and Ubuntu. Help!!!

im wondering how this happens?, I already unlocked my bootloader just cause of this.. maybe the chip just dies?

When my 2013 was stuck at the Google screen, I RMAed and they had to replace the motherboard. Unfortunately, I think this is a hardware issue.

Too many of us with the exact same problem after trying to to flash Lollipop. Cant believe we re all having hardware problems at the same time.

Mine did not occur after flashing any firmware, but the symptom was the same in that I could get into the bootloader, attempt to flash new system images, appear as if all would be well, and then on reboot would stick at the Google screen. Not sure if folks are seeing the same thing here, but when I tried to get into Recovery from the Bootloader menu, it would reboot as if going there, but still never make it past the Google screen. It happened within 18 hours of unboxing a remanufactured N7 G2. Asus advised on the packing slip that is was a LED (Indicator) Error (whatever that is), and they they subsequently had to replace the board to fix it.
I hope it is a software issue, but not sure to tell you how to go about correcting it if you cannot flash new images via ADB or the bootloader and get it to boot successfully.

When i boot to recovery i get the TWRP startup screen but stays stuck.

Its driving me nuts.
I have found though that if I try a "Erase Boot" or similar and pull the cable after a second or so I do get a "OK" instead of being stuck with "Erasing boot..." Seems to work for Boot, Cache etc..
The problem is that when I try OEM Unlock it needs to perform 5 different erases, so pulling the cable wont work for this. I just stay stuck on "Erasing userdata...r..."

So you success?

NO success because I cannot unlock the bootloader.

Another Bricked Nexus 7 after Lollipop

Seems a few are having the same problem as me after trying to flash 5.0
My Nexus will no longer boot past the Google Logo (White one). I can only access the Bootloader. When I try to go to recovery I see the TWRP logo but stays stuck there. I tried flashing a new image a few times but always had the same problem.
I then tried to relock the bootloader and unlock again again to prepare a fresh install. This is where it gets worse. I managed to lock the bootloader but I can no longer unlock. I get to the screen warning that data will be wiped if I choose "YES", but when I do proceed, I stay stuck on "Erasing userdata...". I left it for 5 hours and was still stuck with the same message.
I cant see what else I can do now.
Ive read a few threads saying its a motherboard issue. Seems weird that it appeared when I tried to install Lollipop. Also seems Im not the only one.

this worked for me
I'm sure someone wiser will respond to you later but ..... I've been in a similar situation.
I use Windows 7 64bit and always connect device with usb 2 port (i.e. not usb3).
I was getting stuck on the google logo with an open lock symbol low on the screen - indicating unlocked bootloader. Like you could get into recovery but unable to get any further once there.
Try using Wugfresh's Nexus Root Tool. Look in the development thread. I'd suggest reading his faq's.
Download and install the latest version 1.9.6 (as I recall) - I had problems when using the earlier versions.
Get an stock image downloaded.
Then you should be able to flash the image using the force flash method he mentions in his faq. You set it in the options menu.
Set USB debugging on the device and usb options for storage to ptp rather than mtp - that's what worked for me.
You'll probably see repeated "installing driver" messages and new "open location" popups as you go through it.
(if your bootloader is locked you'll need to unlock it first. - just re-read your original post and I'm hoping that the latest NRT version will get you unlocked OK.)
If you have problems with this at first try going through the driver installation section of the tools.
After that you can use the same tool to root it. That didn't work completely but did allow me to use an OTG flash drive. If you need full root there's a patch you need to flash - Key Pie patch - took me a while to find it but it's somewhere on these forums.
After the problems I had everything went smoothly in the end. Just be prepared to watch it go through various rebootings while the magic is being done.
Apologies if this is a bit haphazard - I tend to try and rush through things and then forget what it was exactly I did!

I have tried NRT but cant do anything as I cant unlock the bootloader. I have tried both Fastboot and NRT, they both block at "erasing userdata".

Just a thought
Sorry to hear that.
Have you tried "Flash Stock + unroot" with the "Soft-bricked/Bootloop" option in NRT? I now recall that's something that helped me get mine recovered. Just a thought.
I recall reading forum posts that suggested I might have motherboard issues - but I didn't believe it was likely to be the case so I kept trying.

Tried all NRT options including force flash.
Problem is none work with the locked bootloader.

Nexus Root Toolkit v1.9.7 out now
Change log:
What’s new in Nexus Root Toolkit 1.9.7: November 16th, 2014
· Included the latest Masterlists to prevent users who never utilized the “Update” in the kit from getting the AutoIt error (for KTU84P Nexus 7 2013). This error was due to the modified boot.img for that build being accidentally removed from the server. Its was then reuploaded and the masterlists were updated, but those users who never updated would still get the error.
· No longer will the “Force Flash” recommendation be made to N4 users, because it seems to cause a bootloop – however factory resting will fix that either way.

IDEM
I spent exactly the same as you, I also lock the bootloader and now I can not do anything, always get "write failure" and when I try to unlock stays forever "erase ..."
There will be some way to revive it?
Cursed Android 5.0!
If the problem is confirmed to be Android 5.0, Google can help solve these problems?

Use the instructions to reflash your bootloader.
http://blog.laptopmag.com/how-to-hard-reset-a-bricked-nexus-7-with-your-pc
Note replace the instructions to download 4.1.1. with the correct version of the ROM you want to flash. Make sure you grab the correct version for your device. Flashing the wrong bootloader can hard brick your NEXUS with no chance of recovery. Also don't relock your bootloader unless you are certain that you will never want to flash again. Unlocking wipes all of your data and you also can't be rooted if you lock it again.

Doesnt work. Cant get passed the first step. After 1 hour its still "erasing boot..."

I flashed 5.0 successfully... You can't send it to Google with warranty? Try on other computer, do it manually using fastboot and don't give up!

As long as you can still boot into Fast Boot..
Your device can be restored..
I suggest using Wugfresh's Nexus toolkit
http://www.wugfresh.com/nrt/
The issues coming from the latest upgrade are common problems when ever we upgrade..
Its always better if you know how, just use the Nexus Toolkit and install the factory image..
Then it will sit at bootup for about 5-7 mins, then restore your apps... Profit
OTAs will always cause issues with some devices..

Again.. I cant unlock the bootloader whether manually trying with fastboot or running NRT. Flashing a stock image is not possible.

If you have not tried the latest version of NRT, you may of fried your locked bootloader..
Regardless, don't give up... Someone will come to the rescue.. Nexus devices are pretty robust..
Try using another cable, make sure you have the correct driver, double check in Device Manager...
Then try again with the lastest NRT.. Mine just updated.. As a rule of thumb its better not to use a USB hub if thats the case.. Try swapping out your cable, make sure you have the Nexus drivers... I had to re install mine..

I'm in the exact same spot. Also, I know that I don't have USB debugging enabled, so not sure if I'm blocked out because of that. Very frustrating.
The computer sees the tablet though. If I click on List Devices in NRT Advanced Utilities, it shows my serial # fastboot.
update: I tried the Unlock command and it goes to the Unlock Bootloader screen. I click Yes, but then the device just hangs on that screen (I let it sit for 30-40 minutes). Ideas?

It hangs because its probably stuck at "erasing userdata". If you do it manuall with fastboot oem unlock you will see this in the cmd window.

I ve given up . Bought a Nexus 9. Wasted too much time on this.

Having the same problem
My Nexus 7 (2013 32gb wifi) was working just fine on Monday. Had an unusual freeze up when I was reading something on Adobe Acro., but a quick reboot had it running again. I remember a notification about a system update but didn't pay it much mind. Later that evening I went to pick the N7 up and it was stuck on the Google loading screen. Freezes at Google loading screen when I attempt Recovery mode from Fastboot. Fastboot OEM unlock gives me the same stall at 'erasing user data' as mentioned above (left it on for this for 12+ hours yesterday and nothing). I haven't tried a different cable other than stock yet but I have tried multiple ports and two different machines to unlock the bootloader so I can flash the OS. No other functions with NRT (1.9.9) work including forced flash+unroot. I can't even flash the bootloader or erase or format any partitions. Feeling a little SOL here and I think it has something to do with Lollipop update.
N7 was unrooted and used for reading for the past couple weeks, so pretty vanilla use over the recent past.
4 months out of warranty with Asus and they want an est. $100 for RMA. Google tossed me to them after dragging me through the basic stuff I've been doing the past few days. Going to keep messing with it I suppose once exams are over but feel like I'm running out of things to try. If anyone has any suggestions, questions or a solution, posting them here would be much appreciated.

My upgrade from 4.4.4 to 5.0.1 took ages. It was like bouncing the four small balls for perhaps 5 minutes. Just have patience.
I would recommend not to use xposed or titanium backup as I expect those programs mess with /system files and that can break the android upgrade script. Just disable any unwanted bloatware in regular application control. At least all my updates have been successful so far. Yes, I am rooted.
Good luck.

For Wugfresh excellent "Nexus Root Toolkit" to work you need to enable usb debugging in developer menu. You enable the developer menu by tapping a lot on your version information.
The usb debugging gets reset on every upgrade.

They quote you $100 RMA, but once you send it in they will send you an invoice for $200. $165 for the motherboard, $25 labor and $10 return shipping. I fought it and they eventually dropped $10 for the return shipping. Last time I ever deal with Asus.

Bricked?!?

Just got the XL on Friday. Loved it.
Unlocked the bootloader about 45 minutes ago. Wiped upon reboot (as normal). Google logo displayed with progress bar but the animation never stopped.
Downloaded the factory image from Nov. Ran the flash-all.bat from bootloader. No errors. Rebooted. Got a "Your device is corrupt" error. Phone stuck on the Google boot screen. Going into recovery just gives me a dead droid.
Attempting to flash the 8.1 developer preview results in the same issue. As of right now, nothing seems to boot at all. I've changed USB-C cables, since I've read about those causing issues, but still the same.

By the way, the dead Droid is recovery, from that screen, hold power and press up for recovery menu, in case you ever get stuck again

And just for future reference for others who may be in a similar issue and stumble across this thread...
As long as you've successfully unlocked your bootloader and "fastboot devices" successfully pulls up your device, you'll be just fine. You just gotta take a step back, breath and then make sure your SDK tools are updated before moving forward.

if the flash tool isn't working, use my script:

If you cannot get the Bootloader to load, then you are seriously SOL. You have a hard bricked device.
Only thing you can do now is raise a support case with Google and hope that allow you to get a replacement with the only explanation being, "The phone restarted on it's own and never came back up." Or something similar and vague without expressly telling them what you did.

Make sure you try a different cable to connect your phone to your PC.. I had the same issue, and I try two different cable before my device accepted the flash-all

The funny thing is I was able to and was in bootloader but I couldn't use any commands from my computer (as far as I know) which is why I was freaking out.
I should've but I didn't actually try using other cables. I did try other usb ports but that didn't do anything.
I still kind of believe that my phone (somehow) got messed up from loading TWRP. I don't know if it's because it is still beta or what but I am like 99% sure it was from that as I can't see anything else being the problem.

just install the lastest fastboot and adb drivers from google and flash the factory image using commands or use any script .
after that everytime my phone got stuck on google logo .
how i fixed - Temporary boot twrp beta2 recovery using cmd (fastboot boot abc.img) "here abc refers to the correct name of the img file" and once booted into recovery go to advanced and select Partition A and reboot.
It will boot up just fine

Something similar for me but with different reason for starting all this. When I did sideload of 8.1 all went well but my camera wasn't working (I saw the same thing in 8.1 DP) so I needed to go back to 8.0 but you can't sideload downgrade. I went to Google to get replacement sent and figure I might try to sort things out with this one in the meantime. I had to unlock to be able to just flash the factory 8.0 image so did that with both the unlock commands, then after that and after update I just got hung on the white screen with google logo. I was able to get back to bootloader with the power button + volume from off and from there I would get to the screen with the android and the exclamation point - I think you hold volume up and then power to go to sideload. Once there I just sideloaded 8.0 and all was good. I do still get the warning about corrupt whatever and have to hit power on reboot or fresh power up but I could redo the locks and whatnot and all seems fine now with camera working.
At the least I got camera back while waiting for replacement.

This cleaned things up for me - still no camera in 8.1 but I got the replacement coming.

So I'm in the same boat as the OP but my bootloader is locked. Am I totally screwed? Is there a way to do any of this when the device won't show up in ADB?

Can you get to stock recovery for a factory reset?

It doesn't even let me get to recover. Picking recovery from the bootloader screen just make the phone restart like it try to go to recovery but then it come back to the same screen saying it can't find valid operating system.

Same happend to me on my first unit when I relocated the bootloader.
Unit resetted and then can no longer find an operating system..
Only option was to call Google and RMA it. I've seen it happen to others on the web as well

Did they accept the RMA? Was the issue after an update or did you try to flash the update using adb or fastboot?

Tell them exactly that. It no longer boots

As soon as I said there was no valid os the rep proceeded to rma. Seem like it a know issue so they didn't bother to transfer me to tech support.

Not sure if you want to try any of these solutions before you RMA, but here's another thread on the same "No OS ....." with several options, might be worth a try?

I ran into the same issue, however I found a solution, perhaps universal perhaps not.
When I enter fastboot mode, my phone shows (until I release the power/vol buttons) the "Start" option that is part of the boot mode. After releasing, I get the "no rom detected." So I used the script at the top of https://forum.xda-developers.com/pi...ol-deuces-bootloop-recovery-flashing-t3704761. I used the script by running it WHILE pressing the Power/Vol keys.
This worked for me.
Note: I let go of power/vol after starting script.

Question Unlocked Pixel 6 Pro - "Your Device is corrupted and cannot be trusted" error after trying to manually flash Dec 2021 factory image

I got impatient and decided to flash the Dec 2021 US Carrier factory image on my unlocked Pixel 6 Pro.
I set my device to OEM unlocking, grabbed the latest ABD/Fastboot files from Google, went into the bootloader and unlocked it w/ "fastboot flashing unlock", and then proceeded to flash my device. However, I now get a "Your device is corrupt. It can't be trusted and may not work properly" error w/ a red triangle exclamation mark upon boot. I can click the power button to get past it and the device will appear to boot, but it stays stuck on the Google screen w/ white background.
I'm able to manually restart into fastboot and fastboot devices recognizes the device.
I've flashed all my previous Pixel's many times before and never came across this error. Any ideas?

You're going to have to use the Android flash tool now. Just follow the link in the Google factory image site. You'll be able to get back to December at the very end. It'll tell you to relock your bootloader Don't do it if you don't want to.

Did you flash disable dm verity first after unlocking the bootloader before flashing a patched system image?

thank you! Using the Android Flash Tool resolved my issue.

I did this exact same thing, unlocked device, and flash-all.bat the December update, except my device was a hard brick. I could get zero response from the device, no matter how long I would hold in the power button. Connecting to computer would chime connected, then disconnect a second later. After the flash-all.bat command, it finished successfully, the phone rebooted to a screen that said software was corrupt and would not boot. Pressed power to move passed it and phone went black forever. Had 98% battery too. Had to send back to google for replacement. Did I miss something, or was it just the super buggy December update that did it. I am now scared to death to root this phone again fearing that I did something wrong, and that it will do this again. Is fastboot flashing the factory image a bad thing now, did I miss something, or was it just some weird glitch?

Hard to say, for those of us who haven't had any problems...yet. I've flashed the full factory image at least twice so far.
Normally, the USB cable and to a lesser extent, the USB port used on the computer, would be my first suspects as to the problem, but since you said it finished successfully, I have no clue.

Do I need to disable dm verity at least once, or is that just completely obsolete now.

When using Magisk 23016 for rooting it is not necessary at all.

The *only* time you *might* still need to disable verity and verification are for some custom kernels - until those kernels are updated the same way Magisk Canary 23016 was, and then they won't need it. If you're not planning on using custom kernels, and just rooting the stock kernel instead, then there's no reason to disable them anymore.

I got impatient and decided to flash the Dec 2021 US Carrier factory image on my unlocked Pixel 6 Pro.
I set my device to OEM unlocking, grabbed the latest ABD/Fastboot files from Google, went into the bootloader and unlocked it w/ "fastboot flashing unlock", and then proceeded to flash my device. However, I now get a "Your device is corrupt. It can't be trusted and may not work properly" error w/ a red triangle exclamation mark upon boot. I can click the power button to get past it and the device will appear to boot, but it stays stuck on the Google screen w/ white background.
I'm able to manually restart into fastboot and fastboot devices recognizes the device.

Did either of you verify the hash of the download before flashing?
Before flashing any image, the hash should always be verified as it ensures the file is secure and not corrupted.

^ This. For years now, I've just gotten used to verifying the hash of every important thing that I download that has the hash value made available. Saves a lot of hassle later on since if the downloaded file is corrupted just slightly, everything will go wrong down the road in the process.
I also check for new Platform Tools and Google's USB driver each and every time I flash a new update. It's just habit and again, saves a lot of trouble.

To add on the previously said:
Windows has a built-in hash checker, you just need to open CMD and type
Get-FileHash <Drag'n'Drop'le'File'here>

Then just copy the hash (strg+c) into your browser search window where you downloaded the OTA/firmware (strg f to open search, strg v to paste) and if you get a match (1/1), the hash checks out.
It's easy, it's fast, it's reliable. It will only cost you a few seconds. No hassle involved.

For anyone who doesn't know, this is referencing Windows' built-in PowerShell. It may be the default these days as Microsoft pushes it and it's more capable than Command Prompt, but you can still open CMD and the "Get-FileHash" won't be available there.

It's often better to use a program that will compare the hashes, else a SHA256 or SHA512 hash becomes tedious to manually compare - I'm partial to QuickHash [GitHub] due to its broad functionality (drag and drop file for it to auto-compute hash and you can paste what the hash should be either before or after)

For quick one or two-file comparisons, I prefer Implebits' HashTab, which adds a new configurable tab to the file properties dialog in Windows. I originally got turned onto the program when it was Beeblebrox.org, which being a Douglas Adams fan definitely got my attention back then but I stuck with it after they sold it.
Edit: I see Implebits is going out of business and HashTab will go to GitHub and be open source, so exciting times!
Implbits Software, LLC is going out of business
We will soon release Hashtab as an Open Source project on Github. Until we do... you can download the last build of Hashtab that we made using the link below:

Actually the same situation here. What's the version of your adb tool. Do I have to use the web tool to flash in the future? Could I use adb with flash.bat as always？

I think you should of used the full image not the update with flashall.bat

I had this before as well after manually flashing the November update. Got the device cannot be trusted. Rebooted, flashed again, and device completely fried. Wouldn't turn on, not recognized by computer, nothing. Complete brick. Suspect system board fried. I'll never try to manually flash an update with a Google device again. Hopefully it ends better for you.
