I'm bricked .. Getting worries. (Yes I've read the forums ...)

Attempted to flash Liquid Jelly Bean, then got stuck on the animation boot screen. I've tried Root tool kit for unbricking and setting it back to stock. Tell me it's successful but stays stuck on the animation screen.
I've also tried to unbrick manually however even though I have the correct files placed in my Platform Tools folder of Android SDK ... I constantly get stuck at the CMD prompt steps. Any time I type in "ADB reboot loader" or ..."fastboot flash bootloader bootloader-grouper-3.34.img" or anything similar I get the error message in CMD saying "___ Is not recognized as an internal or external command"
I'm not sure what to do. The bootloader does say that my device is locked, I just can't get passed the splash screen!

"I've tried Root tool kit for unbricking and setting it back to stock. Tell me it's successful but stays stuck on the animation screen. "

Here's an update:
I think I've made it worse ...
Nothing will boot now and it's currently locked. Any time I hit "Start" it says "Booting Failed"
My CMD now says; Error: Cannot Load "Bootloader Grouper-3.34.img"
I'm seriously lost. I've been working on this for about 6 hours now ....

Can you get into bootloader and then recovery by holding the power and volume down buttons? Was ADB actually working before all of this??

Nope. Nothing is allowing me to get into recovery. At first it was just stuck on the google screen now it says "boot failed"

No I can't get into the recovery at all. When I turn on the device I don't even need to use the rocker keys to get into bootloader either. Actually my bootloader is a bit different now too. I have the 'Google' logo and at the top the regular options for Start, Recovery, Power Off, etc.
In simple terms: I can't even get to the animated splash screen anymore

Open the command prompt IN the directly WITH fastboot
Fastboot oem unlock
Then wipe / flash factory images. Fastboot -w update image whatever the image name is.
Then uninstall / delete that stupid toolkit and never use them stupid craps again.

Are you still able to communicate with the device via fastboot? If you issue the command 'fastboot devices' does it return a serial number?
Edit: I'm going to bed so if you are able to use fastboot, download the factory image pack from https://dl.google.com/dl/android/aosp/nakasi-jro03d-factory-e102ba72.tgz
Extract the archive. Inside are there will be an install script, manually issue the commands contained in the script in fastboot. The only thing you need to add is the location of the .img and .zip files from the archive you extracted e.g. 'fastboot flash recovery c:/Users/name/desktop/recovery.IMG'
There is no reason this will not get you up and running again.

Thanks for your response.
I've followed the instructions in the file. From previous research, I've had these files. My device does communicate with Fastboot. When I give the command for Devices it gives me my serial. Also, when I ask it to reboot-bootloader in CMD it does.
My issue is when I get to "Fastboot flash bootloader-grouper-3.34.img". CMD states "Error: Cannot load bootloader-grouper-3.34.img"
I've followed the commands previous to that. (Erase boot, cache, recovery, system, userdata)

Fastboot oem unlock

Yes my device is unlocked again, but I still can't get into recovery mode. It just tells me "Recovery Failed" in small text in the upper left hand corner of my N7.

UPDATE:
After unlocking the device again. I used the Nexus Root Toolkit to restore to factory settings and it worked
The Problem: My device was no responding correctly to the toolkit when locked.
Cheers for the help. I'll attempt to root again, hopefully no problems this time If there are I'll be sure to post again!
Thanks to everyone that replied.

For the love of God..stop using the toolkit from here on out.. learn how to use ADB and Fastboot so you can avoid these issues.

So you erased the recovery then wonder why you could not boot into recovery....
You flashed or tried to flash the bootloader. You already had the same bootloader installed and there was no need to do so to try and fix your issue.
You still don't know what you're doing and are back using the tool that lead you to this issues. A toolkit. Learn what you're doing and you wont face this type of silly issue again.

Don't use toolkits. Most people don't have a clue what the toolkit is actually doing so if something goes wrong they aren't in a good position

Nexus 10 Boot Loop after OTA 4.4.3 Update

I have a Nexus 10, rooted but still running stock. I clicked the 4.4.3 OTA update, it updated, and restarted in a boot loop. No idea what went wrong with the update.
I went to Recovery Mode and did a factory/data reset, but after that completed, it was still in a boot loop. I noticed the system recovery says "K0T49H", which is 4.4.3 that didn't install correctly, so I'm thinking maybe factory reset is out as an option.
I also tried entering Recovery Mode and applying the update via adb, but it says "Fastboot device was not found".
Any ideas on how to get it running again?

It says "fastboot device was not found" because Fastboot is only for when you are in the Bootloader. ADB is for when you are in Recovery, or booted into the Android OS. Since you already did a factory data reset, I would assume you don't mind losing data. If that's the case, just boot into the bootloader and flash the entire factory image for 4.4.3.

Oh. You're using a toolkit... Sorry, can't help you much then. I'm not a big fan of toolkits for this very reason. It's much easier to figure out what went wrong, and where, when you flash everything manually. However, it sounds like there's a driver issue. Make sure you still have the correct drivers installed. That's all I can think of.

NICE! Glad I could help. These Nexus devices are so easy to flash manually, so I don't really see the need for toolkits for this device. I can understand other locked down devices though. After I picked up my Gnex, doing everything manually was how I learned the basics of ADB and Fastboot.

Hi,
Glad to see that you solved your issue, could you please add a [SOLVED] tag to the title now?

Soft Bricked Nexus 6P With Locked Bootloader (Need Help)

My Nexus 6P is stuck on the Android boot animation after installing the Android Beta OTA that came out today. I waited like 30 Minutes and nothing was happening so I tried Clearing Cache which did nothing then factory resetting, Clearing Cache & Even sideloading the OTA using ADB to no avail. My huge mistake was not having OEM Unlocking enabled so now I can't even flash stock android.. I know this is my fault for being so stupid but is there anything at all I can do to save my phone?

I'm in the exact same boat...hopefully something can be done, but I'm afraid we're idiots for not having checked OEM Unlocking. I've tried adb sideloading the OTA image, but as you said, with a locked bootloader, we've got nothing. Anybody have any ideas?

You might be able to use ADB to modify the OEM Unlock setting while booting.
Also, if you ever plan to mess with your OS, especially alpha/beta versions, always have your bootloader unlocked to prevent issues like this.

Use Fastboot boot [[[name of latest twrp]]].img (make sure the .img is in the adb folder on your pc) and then do a full system wipe (not just factory reset, but literally everything, internal and external -- access this from the advanced menu in twrp). That should boot you into the system so that you can enable oem unlocking, unlock the bootloader, and carry on like normal.

Can't boot twrp.img because the device is locked. Anything else I can do?

I had something similar like this happen, for my fix, all I did was boot to bootloader, cleared cache and then did a complete shutdown, do not just reboot, just rebooting, would go thru the boot loop, but a full power down allowed it to boot up normally. Not sure if it will help in your situation, but it's an easy try

No luck for me, unfortunately. Keep in mind that I tried to sideload the OTA.zip with a locked bootloader before doing this, so that may have made this process not work. For those who haven't tried to "fix" their failed installation like I did, give the cache clear a try first.

Apparently some people can use the fastboot format command while their bootloader is locked. You can try booting into the bootloader and issuing these commands. (THIS WILL WIPE YOUR ENTIRE DEVICE INCLUDING SDCARD/INTERNAL STORAGE. Of course, your device is now bricked, so I'm sure this is fine for you.)
Code:
fastboot format cache
fastboot format userdata

Hello guys. I'm having the same problem here: installed the update last Thursday, apparently didn't have usb debugging checked on and I can't get past the boot animation.
Tried everything: format several times, cleared cache, sideload, etc. I've tried to sideload this package you guys are talking about but unfortunately this doesn't work either... In cmd it says <waiting for devices>. Tried different usb ports and everything - still nothing

Locked bootloader 7.1.1 ota preview help!
I have the latest preview build directly installed ota from Google. The phone just started bootlooping the other day for no apparent reason. I didn't have the developer options on or oem unlock enabled.
I can get to bootloader mode and recovery mode. I have wiped and reset from recovery with no help. I can access adb and fastboot on the pc but it won't let me write any files because of the locked bootloader. Anything I try to sideload so far gives an error. Any further suggestions?

Bootlooping Nexus

My Nexus 6P is seemingly bootlooping.
I can boot into the bootloader menu but not into recovery. My bootloader is not unlocked so I cannot flash anything.
Issuing the command: "fastboot flashing unlock" does not work nor does "fastboot oem unlock". I cannot flash a custom recovery. Because my bootloader is locked.
Any help would be great.

You say that your bootloader was not unlocked, so I'm assuming you didn't have developer options turned on and USB debugging checked before fastboot flashing unlock?

Do you remember if you modded anything prior to bootloop? The reason you can't unlock bootloader is because USB debugging isn't on. What version of Android were you on when it happened? I believe you can still use google factory Image to restore your phone.

Since you don't have twrp you probably don't have a backup, which what I'm going to suggest will bring you back to stock and may lose everything. Though it's better than a bricked phone. Since I never did the flash-all.bat you may lose your stuff on internal SD. In this link, download the correct image your phone was on (under angler) and if using windows use the flash-all.bat in fastboot. If you're phone isn't 32 GB, extract all from zip and flash everything except user data. Forgive me for assuming you may be new. https://developers.google.com/android/nexus/images

Do you get the error on all that you try to flash? Maybe just try the recovery img only to see if you can at least get that. If that works you should be able to sideload ota through recovery. With having a locked bootloader you might be at a loss. But on the flip side, having everything locked and not rooted you should be ok for warranty replacement.

Tried running through those steps. I can't even get a temporary boot of TWRP or stock recovery continues to bootloop even though WugFresh claims it was successful. Tried doing it manually via Fastboot and continue to get the error in flashing.
I just received my replacement phone. So I might just call it a day on this one. :crying:

Good to hear about replacement! There are a few people in these forums that have a brick and can't get out of it. I thought you couldn't Hard brick these phones unless that was your goal. And most of these users who have bricks don't even know what causes it. Just a random reboot then loops. Kinda scary.

How to lock the bootloader?

Hi,
I have TWRP but I want to use the default bootloader. Is there a way to restore it back to stock without losing my apps and settings?
I downloaded (A2017UV1.1.B35 (Nougat) (Post # 2 or Click Here)) from here:
https://forum.xda-developers.com/axon-7/development/rom-guide-updates-to-stock-files-via-t3469484
https://androidfilehost.com/?w=file...c9cf15e47b9a9c4af6f1239b585792c06c0520ebc3480
I extracted the recovery.img
then I followed this:
https://www.theandroidsoul.com/how-to-install-twrp-recovery-via-fastboot/
But after I type this:
adb reboot bootloader
I am in the booting black screen for 5 seconds, as the loading screen tells me, before it reboots. Either way when I call this command right after:
fastboot flash recovery recovery.img
I am getting "waiting for device" print and it never finishes. Before that ADB sees my device. What do I need to do so I can fix this?
Thanks in advance.

First of all it would be a good start to actually get fastboot mode :laugh: You should actually follow a guide instead of trying to do this by your own. Find a guide for the U (assuming that you have an U). You'll have to install fastboot via miflash or whatever

Thanks the guides I found online all advise to use that fastboot command. That's why I couldn't figure it out. I have A2017U yes. Do you know any guide for this?
I will google more using your miflash keyword. Thanks again

The toolkit can do this for you. Make sure you are 100% stock bootstack, recovery, and system, with everything working, before you attempt to lock your bootloader. Lots of people ignore that warning and brick their phones. I'm not sure if your apps and data survive a lock.

I tried to lock mine via adb and bricked it. Luckily, the RMA people believed me that it was a failed software update and fixed it for me. I wouldn't try to do that again ^^
