After Android tried to update itself to the newest version, it seemed that this failed and has caused a "boot failed" message. The tablet refuses to go into recovery mode, its marked as red. The only accessible mode is going into bootloader. After reading many forums and trying my luck with toolkits of all sorts (Nexus 7 Root Toolkit, Nexus Root Toolkit, Android SDK commands), the bootloader refuses to unlock. I have successfully installed the usb drivers since my pc recognizes the device. fastboot devices recognizes the devise but adb devices doesn't. The bootloader is locked and nothing else is accessible, whats worse is that through all of these toolkits and commands bootloader refuses to unlock, trying to unlock it always results in a failure message (unknown error). Commands such as format, unlock or erase fail in reviving the system. Anyone have any experience with this? I have searched for over a week now and im terribly frustrated by this. :silly:

do it the right way, dont use toolkits.
to unlock the bootloader, go into the bootloader(fastboot), connect the divice via usb, type..
fastboot devices(to make sure your device is visable)
fastboot oem unlock(to unlock the bootloader)
if you get an error, reboot the bootloader and try again. i had an error the first time on my replacement seven, second time it unlocked.

Thanks for the reply, i tried this several times, each time rebooting bootloader, but the command still posts an error in unlocking the bootloader. Recovery and Restart bootloader are marked in red font, Start is in Green, Power off White. I also tried flashing the recovery, since its inaccessible but because of bootloader being locked in won't allow me. :S Anything else you know that can be done ?
Reflash the bootloader?
edit: making VERY sure that you DON'T erase the existing bootloader first.
Try a manual update

You can try a manual update. Download the update and run adb sideload. That was not working for me, cause my Nexus it's allready updated, but hopefully it will work for you.

fortunatley though bootloader doesn't allow any command even the erase, it wouldn't allow me, nor formatting it as well. So i think the bootloader is intact. This is the screen i get from pressing Power and Vol Down.

As i have come to learn, adb can only function when debugging is enabled, in my device it wasn't unabled. Also the recovery program cannot be opened so sideloading through commands cannot be done. At least according to how some forums described the How To sideload through adb

Use the volume up/down keys to navigate to "Recovery mode", then press the power button.
When the Android with the red exclamation point appears, hold down power first, followed quickly by volume down and volume up. (So that to start, you're holding down power, then you're holding down all three). After 2-3 seconds, release all three keys.
Use the volume up/down keys to select "apply update from ADB," then press power to select it.
On your computer, open up a command prompt or terminal window.
Using the command line, navigate to the folder containing the ADB executables and the update file.
type:
adb.exe sideload <update filename>
On my Nexus with Jelly 4.2 usb debugging is not enabled too, but I still get the option in recovery mode menu. Operation not succesful cause I cannot upgrade from 4.2 to 4.2. I will wait for another update and then try it again. Good luck!

Unlock Bootloader on 4.2
Hello, I was wondering if the bootloader in 4.2 can be unlocked the same way as it was on 4.1.2? I recently got a new nexus 7 and updated to 4.2.
Thanks and Cheers!
After some research into my issue, i have discovered that other users have posted "unbricking" solutions through a program called nvflash, when the device is put in APX mode. But unfortunatley i've yet to find a nvflash solution for nexus 7. I will experiment with the commands and what the others have reported as a solution.

First thing first... connect your phone and type "adb devices". Does your serial nr show up? Turn off your phone and boot into bootloader (hold vol up + power). Type "fastboot devices", does your serial nr show up? If not, adb and/or fastboot isn't recognizing your connection and device. If it does, you SHOULD be able to type "fastboot oem unlock" to unlock your bootloader.
Tip: you can view your bootlooader state on the device display when inside the loader. It says "State: LOCKED" or "State: UNLOCKED" respectively.

Yes that Odin package from Samfirmwares is for the I9020T. However it is not version 2.3.3, but rather 2.3.1 GRH78.
I have searched and couldn't find a fastboot thread. So here it is.
I found out fastboot is working on Linux.
Bad news is Windows seems to need another driver for fastboot.
Please help look for a windows driver or make one.
The fastboot commands all seem to work fine.
Here you guys go! Enjoy.

In the Fire TV section a fastboot cable was created by splicing two USB A to B cables together, so that the A to A ends were together which when connected from your computer to the Fire TV on bootup put the device in fastboot mode, in the process then your computer recognized (Running Windows 8 was the example given) the device and installed the proper drivers. Since the devices are similar, a potential solution would be use the cable, have the computer recognize it and install the drivers, then backup the drivers, and share them here for others to use.

I'm quite sure the cable isn't the issue. Also that's just it, I can't get windows to recognize it or find much info about it. The adb driver for the device isn't enough I guess. The funny thing is windows says it's working properly as 'Kindle' for a little while when you plug it in (while in bootloader) then device manager refreshes and reports 'cannot start'. I tried launching 'fastboot devices' many times but still nothing. I think it needs a software fix and not a hardware one but I have no past experience using fastboot. So... noob alert.
btw the driver windows tries to use is ms_comp_mtp(Generic driver installed=true) and adb uses the Amazon one on the fourm here.

I have a problem
I don't think there's ever been a question of getting into fastboot mode by using the adb reboot-bootloader command.
The issue is how to enter fastboot if the device is semi-bricked.
The device has source in the original bootloader to boot into fastboot mode if both volume buttons are pressed while powering on the device. But this has since been altered and now will only work if the device is unlocked.

Fastboot works with win8? Not with win7.1 If you have fastboot working with win8 please go to device manager (when your in the bootloader) click properties on the device then look for what driver it uses.

always go to grey screen logo...

I think all that works is reboot into fastboot mode. Windows 8 says no drivers are loaded. I tried a command (can't remember what) and it just went out to lunch so... I guess windows 8 isn't working either. Only to put the device in fastboot.
there are three oem commands:
oem device-info
oem idme
oem relock

but it doesn't support oem unlock so there must be another way of unlocking the bootloader, when you try some of the commands the device returns "not allowed for locked hw". Does anyone know what the "hw" is ?
hw = hardware?

Hi,
I have a bricked kindle hdx 8.9 that stops at "Kindle Fire" boot screen. I am a newbie at these things.
Just discovered that it still respond to some adb queries. Sounds like there is still hope to recover... Could it be the bootloader is messed up? Anyway to reload an image boot file to repair?
Also "fastboot reboot-bootloader" puts it into fastboot mode...with the status "ready"....and i just dont know how to proceed. Any one can help?

Facepalm
just back a little: was rooted in April but with subsequent amazon auto updates - didn't have su status. But I was able to load apps & files, installed vpns, quite a few docs,mp4 files, etc. Not really using much of the new freedom or whatever was left of it... Nothing exciting.
Was working well until one fine sunday afternoon, just 2 weeks ago when it just simply stopped after rebooting from a previous low battery charge. Was told it could be an interrupted routine update when the battery power just fell below threshold - but thot it wouldn't have erase the previous image before the new update is effective. Or it could possibly be a deleted file that is related to the booting process as I did a bit of clean up prior to the last reboot?
In the meantime, I did some adb shell/pull to explore or extract the files, photos,etc in /sdcard & other places back to my PC just in case they were not backup by the cloud. Maybe it was not bricked...but just lost a boot file or something...
In a bad situation, have absolutely zero ADB access as my build.prop is botched (bad permissions) and I did a factory reset in hopes of recovering. There is a "fastboot cable" on amazon that says it will reboot a hdx into fastboot mode, but I'm unsure of it's legitimacy. Help?

I don't know if this will add anything to the discussion...but I can confirm fastboot is working on Ubuntu 14.04. I am using a kindle fire HDX 7" and it detects it on devices..and most commands work. Sometimes the terminal must be closed and reopened for commands to go through..

Hello all! I'm having a problem with a Nexus 7.
This is my brother's tablet that he hasn't used in a few months. It hasn't been unlocked or rooted.
I can get to the boot screen with the android lying on it's back and the options with the volume buttons. The other info on that screen which might be pertinent:
Fastboot mode
Product name: grouper
variant - grouper
hw version - er3
bootloader version - n/a
serial number -
signing - not defined yet
lock stated - locked
When I go to recovery mode and push the power button, it says "booting failed" in the upper left. It still says Google in the middle, and has the options with the volume in the upper right, but the android is gone as is the text in the lower left.
I have adb and fastboot installed, but I can't seem to do much since the tablet is locked. I tried unlocking a few times, and it's always failed. Usually it doesn't give a reason, but one time I got this: "Failed (status read failed (Too many links))"
I've tried googling this and can't find someone with the same problem.
Anything I can try?
Thanks!

If you can get into the Bootloader, just run the below via ADB
Code:
fastboot oem unlock
Once you unlock the Bootloader you can use the "Soft Brick" Mode in the NRT to Re-flash back to stock and see if that will allow you to boot. You do not need debugging enabled to use the Nexus Root Toolkit if you use the Soft Brick mode, but you must have an unlocked bootloader.

What says "unlocking" (computer or tablet) and are you trying to do it through the Toolkit, or via command prompt ADB? I would first make sure your computer is seeing your tablet (ie. that the drivers and Fastboot are installed correctly). Do you know that they are?

I was trying this with the command prompt. I could get fastboot to list the device when using that command. And the tablet and command prompt both say "unlocking" when doing that. I would assume that means the computer is seeing the tablet and everything is set up correctly?
I think I tried to unlock with the Toolkit, but I believe it told me that device needs to be in debugging mode.
Hey there, I'm having a similar problem.
My info is the same except my bootloader version is 4.18 and my lock state says it's unlocked. I tried to use the root kit but I'm having trouble with the fastboot device being detected. Driver solutions attempted were the google ones, and the pdanet ones. I can't really do the manual thing since that involves the device being recognized when plugged in, and since I can't enable usb debugging... anyways the automated drivers windows says were installed successfully so I don't really know what else to do.
Note: I do know the usb port on the tablet and computer work since when plugged in, it will show that its charging with the white battery icon.
Same issue here
I was in the process of upgrading manually from android 5.0 to 5.0.2 owing to the serious lag that came with lollipop. The OTA was taking longer and testing my patience as most apps were crashing due to lag.
Therefore decided to go for manual flashing of the image. I have never done this before. I was able to make the computer see my device by disabling mtp via storage under setting in the device. This is one thin I noticed to make the device visible to the computer.
After installing the device drivers my nexus was visible within the device manager but it couldn't be seen as an external storage until I played with the MTP. I had even unlocked the boot loader before all this.
So everything was going well and while I started to think all is well, I ran into this issue. From adb I tried to run 'flash-all.bat' from the new device image. Something went wrong somewhere - don't know what it is, but from then on, I am stuck in the fastboot screen or into recovery mode but when i try to boot the device bu hitting the power button - I get this message 'Booting failed'.
I am also trying to use NRToolkit but no use. When I connect my device it is seen in the device manager in my pc but cannot see it as a storage. Therefore when I now try to run the 'adb devices' command it cannot see my device. From what I saw initially, until I enable/disable mtp mode adb was not able to see my device to communicate.
Now when I tried NRT and installed the drivers once again, it is being detected in the device manager but when I run the driver test within NRT - I get a ADB device not found error. Within NRT all that it says is go into device setting>storage to enable it which I know but at the current status of my device in boot screen/recovery mode how can I go in to enable this. This is not helpful.
Somebody please suggest a workaround for this issue. I know I am close to the solution but not sure how to enable the MTP or at least made the NRToolkit to say 'ADB device found'.
My fastboot screen shows these details:
Fastboot mode
Product name grouper
Variant = grouper
HW Version – ER3
Bootloader version – 4.23
Baseband version – N/A
Serial number – 015d21d910141c0a
Signing – not defined yet
Lock State - unlocked
Please help.
Hi guys,
I searched forums, web with no positive results. So I start a new thread. Here is the situation: one day my Nexus S (Worldwide edition) froze on restarting with the Google Logo on the screen. Every time I try to turn the phone on it stacks at Google logo. When in the fastboot mode the status is Locked. Every time I try fastboot oem unlock I get Phone’s prompt with Yes or Not to unlock bootloader and after choosing Yes, the status doesn’t change to Unlock. Tried on Linux, Mac, Windows (drivers installed successfully), the same result. Tried to force Flash Stock + Unroot in Wugfresh, doesn’t work due to the Locked Bootloader.
typing "adb devices" in cmd (should return the device number) shows:
List of devices attached
......
Empty line above
Any word of advise how to force Unlocking the Bootloader would be greatly appreciated. Please help. Thank you!

It looks like your device is not recognized in Fastboot mode...
Have you turned on USB Debugging while connecting PC and Allow in Device when Prompt some message ..
Go to fastboot mode and write this command... fastboot devices
If it will give you a message like this
List of devices
1235456785164
Then your devices is successfully recognized...:good:
It is not recognized by adb devices, but:
fastboot devices - gives the following output:

fastboot oem unlock - gives the following:

Pretty sure you have a bad USB cable, the error means the fastboot binaries are working on PC but can not connect to device, often this is due to a bad USB cable or port
Try a new cable, one you can verify works transferring data

Thanks, I tried 3 different cables on 3 different operating systems, with the same problem unlocking the fastboot. When I send fastboot oem unlock the device opens a prompt with Yes or No choice, but after choosing Yes, it stays Locked
Something indeed is strange...
So fastboot is for bootloader and adb is for within os and in recovery.
Try booting into recovery and see if adb works, also boot normal into your bootloop and see if adb works there too

Loading into basic recovery and trying to wipe data/factory reset - doesn't work. adb devices returns the following output:
./adb-linux devices
* daemon not running. starting it now *
* daemon started successfully *
List of devices attached
****empty line here****
Somehow, adb doesn't recognize the device, whereas fastboot devices shows it.
Is there a way to flash new bootmode with the currently locked bootloader?
Thank you!

UPDATE (resolved)
Here is an update. Hope this would help others with similar issue, as I've read many threads and folks complaining that they weren't able to unlock fastboot and further root their Nexus S, and who can't boot the phone, which stacked with Google Logo (soft loop). This was the case with my device and finally I got it resolved. I've read some guy tried to hit the phone and after that he was able to boot phone normally. It related to some hardware electrical circle issue. Anyways, I tried to hit my phone by placing it under the direct sun in balcony for some time until the phone got hot and then power it on. And ooops, my phone started booting passed by that Google Logo which was the good sign. Once the phone booted up, I went ahead and activated USB debugging and restarted the phone into the Fastboot mode. while the phone was still hot and in Fastboot mode I run "fastboot oem unlock" and hey, fastboot is Unlocked! Again, this was done while the phone was hot, any previous attempts (read above) weren't successful. From that point, I went ahead and rooted my Nexus S by Nexus Root Toolkit, available on wugfresh.com/nrt, without a slightest problem. Now my phone is fully rooted, bootable and working fine. I thank all who replied to my thread and tried to help and hope this info would help someone with the similar issue.

Got to OnePlus support center and go in download section and download official ROM. Hold power and volume up bottons and connect it to PC. After that go in folder where adb files are located on your PC (If you don't have them, search on Google for "adb install 15 sec"). Hold left shift on your keyboard and right click your mouse in that folder on an empty space. Click something related with command window and type "fastboot devices". If you get some kind of feedback it's 2minute of work! If you don't have anything come up, try to start your device in fastboot mode again (second sentence in this post). After you got a feedback from command "fastboot devices" flash custom recovery (I suggest TWRP, Google it and download the .IMG file for your device). To flash a custom recovery type this in command line: "fastboot flash recovery IMAGE_NAME.img"
*replace IMAGE_NAME with actual image name...
After that boot in recovery by disconnecting the phone and powering off the phone. Press and hold power button and volume down buttons till blue TWRP logo appears. After that connect your device on PC and transfer your .Zip file(ROM) to internal memory of your device. You should go back to main menu of recovery and select wipe>advanced wipe, select everything BUT INTERNAL STORAGE!!!***IMPORTANT***
Then you just install ROM like you would normally do...
Press thanks it i helped! Hope I didn't missed something.
This is written in mind with that you have unlocked bootloader like you have written in your post...

Fallow this and don't trust any guides written out of memory with likely any mistakes.. (no offense)
This guide has various approaches to recover your phone, remember to research first and don't type carelessly any adb commands, it's not enough to just tick "oem unlock" in developer options, you'd have to type command on fastboot too, to unlock the bootloader.. there are many guides and youtube tutorials on this subject, absolutely unnecessary to blindly kill it, anyways I'll never understand how you can be so reckless with your phone..

Don't!
If you get no joy from following the instructions in the link given by @Sam Nakamura, try @fareed_xtreme's Official OP2 Stock Reset to OOS 3.0.2

Aight thank you i had some suspicion it might be ...-bricked didnt know which though so thank you
If you can get in the bootloader then possibly the device is still OK. Just need to get the right ROM.
Try different TWRP versions. Sometimes, one particular version can save the world.
