Hi, I am a Nexus 7 user and was tried to root my device using the Toolkit v1.8.2
I am not experience in rooting Android machine, this was my first time and unsuccessful. My device is now could not be started up.
The following is all information I summarized for this exercise, and would like to seek all advice on the followings.
--1 Is my device "recoverable" if yes, how and what do I need to do please?
--2/ or is it definitely "bricked" so I have no chance to recover it at all.
I am totally in-familiar with rooting machine and I have no access to Linux machine.
Any advice is welcome.
Thx in advance.
Machine: Nexus 7 v2- wifi version Android 4.4.2, Build - KOT49H
Computer: Windows 7 64 bit system
Nexus Root Toolkit v1.8.2
Worked procedure:
1/ Follow the "Initial Setup - Full Driver Installation Guide- Automatic + Manual"
Step 1 to Step 4, install the drivers on the computer. and "Full Driver Test" passed
2/ Click "Unlock", pressed "Y" to proceed. - Device went into a screen asking me to select and confirm, I used the "Vol +" to select "yes" and pressed "power" to confirm, but nothing happened on both computer and device after the "power" switch was pressed. Instead, it freeze the device. nothing is responding even after 10 minutes.
3/ I have pressed the "power button again for 5 sec. and device shutdown to black screen.
4/ Since then, every time I try to start the device, the machine first show a "Google" , then a "rotating flower pattern" and won't started. i.e. - "the flower pattern" keeps looping.
5/ on the computer side, no matter what command is given in Nexus Root Toolkit, a notification of ADB device was not found error comes up.
Consequence
A) Device can be switched on and off by pressing "power" button. when switch on, it display "Google" , then a rotating flower pattern, and never end.
Switch the power button for 5 sec again, device switch off.
B) When device is off, press 'power' and "vol -" will switch on the device to a menu with a robot lay down, options "Restart bootloader", "Recovery mode", "Power off" and "Start" can be selected.
C) For "restart bootloader" the screen goes black for 2 sec, then the menu appear again with "Start" option. i.e.- no error no message
D) For "Start " - the device just just act like normal start, end up in a looping rotating flower pattern.
E) For " Recovery mode" - device screen goes black for 3 sec. show "Google" then show a dead robot with an exclamation mark on it, message " No command" is showing. - After awhile, device restarted and end up in the rotating flower pattern.
F) When plugged in, Window 7 can detect the device, when teh device is in the menu, "Android Bootloader Interface" is shown in Windows Device manager, when the device is starting, " Nexus 7" is detected in Windows Device manager but not both.Hi, I am a Nexus 7 user and was tried to root my device using the Toolkit v1.8.2

I'll take up the task to help you. You are not bricked. You are stuck in something called a bootloop, which is basically when the device enters the boot sequence, but never finishes. The flower pattern that you are looking at us called the boot animation. The computer never recoginizes the tablet through ADB because the tablet never gets to that point.
The screen with the Android laying on his back is actually the bootloader itself. That's why restarting the bootloader brings you to the same screen. I actually want you to be in the bootloader screen. You already have the Nexus 7.2 drivers, so you're ahead of the game.
You also need to visit here to download TWRP 2.7. You also need to put the file in the same directory as the fastboot and adb files.
You need to boot into the bootloader, and run the command:
fastboot flash recovery <recoveryname>.img
This should get TWRP onto your device. You can then download a rom of your choice to put on the tablet. Since you will not have access to place files on the device through USB, you will have to sideload it. First, let's get recovery working, then come back to me if you need help sideloading the rom through ADB while in recovery.
Dear aarsyl,
Thx for your help and it is much better to know my device is not "bricked". Thx again!
Thx for your detailed explaination and I feel much better by knowing a little bit more on what is going on.
>>>>You also need to visit here to download TWRP 2.7. You also need to put the file in the same directory as the fastboot and adb files.
[I also found it in my computer already .\WugFresh Development\data\Recovery_Custom\TWRP
but I downlaod it again from your link and put this file in the same directory where I find the fastboot.exe and adb.exe, which in my case is .\WugFresh Development\data\ ------ done.]
>>>>You need to boot into the bootloader, and run the command:
[- I supose you refer to my Nexus 7, so I will switch it on with the "power button + vol -" button. and get it into the bootloader.]
>>>>fastboot flash recovery <recoveryname>.img
[Here I got an query, what image file I need to use? is it the <openrecovery-twrp-2.7.0.0-flo> ? Do I neeed to run it as an adminstartor in Window 7?
so, do u mean I need to type: fastboot flash recovery openrecovery-twrp-2.7.0.0-flo.img ?
is it right?--(A)
if not, then I am not sure what recovery file to be used!
I do not have any other img file in package I downloaded previously

Not quite understand it this bit, but as you say. it can wait later.
So assume I do the "fastboot flash recovery <recoveryname>.img and get the TWRP on the Nexus 7.
What do I expect to see from the nexus screen. Does it have any note saying completed, or shuold I expect a reboot of the Nexus.
I think one of the problem dealing with these kind of thing is lack of acknowledgment fromt eh machine so we do not know if the operation is successful or not.

I decided to have a go with the downloaded twrp img file.
I launched the command " fastboot flash recovery openrecovery-twrp-2.7.0.0-flo.img" from a command window as an adminstrator.
The command failed with an error saying (remote: Bootloader is locked)
And when I check the Nexus 7 screen, it does said "Locked Status - locked" in the last line.
photo showing both the computer and teh Nexus 7 screen.
Oh, I hadn't realized that you were still locked. No wonder you're not getting anywhere.
Reboot into the bootloader, and run:
fastboot oem unlock
Follow the screen instructions to unlock the bootloader, then run the command to flash the recovery. I advise changing the recovery name to something shorter and simpler, like twrp27flo.img, for example.

Hi, Nice to have reply from you again.
Ammm. I switch on the device to the bootloader alright. run teh command "fastboot oem unlock"
On teh command window, it said" < waiting for device>
and there is no visible change on the device screen.
It already last for 10 minutes now.
I do noted that both windows are freezed and do not respond to key press and button press respectively. No responds on both the device and computer.
How lond does this process take to show the mentioned "screen instruction"? I don't see one!

wow.. it is unlocked now!
Should I continue to use the "fastboot recover command with TWRP file" as per your advise or should I continue to use the "Root" command in NexusRoot Toolkit ??
It is very happy to see there is progress.. Thx...
please keep coming...
I would go with using fastboot to install TWRP. In truth, to truly "root" your device, you actually need a working rom on the device. Otherwise, rooting will be in vain. Unlocking the device was the most important.

Hi again,
Yes. my device is now boot up as brand new.
One side observation though, every time I issue command through window 7 in a command window, everything will freeze up, (not remember if I unplugged the device) until I press the power button to restart the Nexus 7. Same for the last time when i did the unlock and this time recovery.
The hesitation was how do I know when to do this, was worrying there is still some communication between the two machines if I unplug or interfer, may just disturb the communication and corrupt files. -- I normally give it some 10 minutes before I do the unplug and restart. any comment or advice?
Anyway, the device is now up and running. What is the status now? is it with the original version of software? or TWRP version or what?
The device is now remain "unlocked" - is it ok or I need to lock it again?
You have mentioned to download a "Rom", what about it, it is only need if i want to continue to "root " the device?
Sorry for so much question.
I am so happy to see it comes alive again but really would like to understand the current status of it.
Thank again. aarsyl
To be honest, I'm not entirely sure what the status of your device is right now. I was under the implication that you had no Rom on the device. Since you are trying to root for the first time, then yes, you are on the stock software that comes with the device. If you search your app drawer and find the SuperSU app, then you are already rooted, my friend. If it is not there, then search for SuperSU 1.94 in Google, and download the zip file. Then reboot into recovery and flash it.
In other news, I am happy that you got your device working, and I am more than happy to help. The only thing that I don't do is recommend roms. I encourage users to explore different roms for themelves.

Well, sure I will continues to look up the information from the basic, but at the moment Would you please enlight me for the following 2 questions
1/ Should I uncheck or check the USB debugging tab under Developer options - it will be very good if you would like to explain a little on what it does, so I will have a more l\idea what it does when when do i need them.
2/ As i said, teh device is now unlocked, is it ok to leave it unlock or should i have it lock? - again if you would explain a little more on this that will be marvest.
cheers

I'm sorry for the long delay. I got locked out trying to log in after I changed my username twice, and it just got messy for me. At any rate....the SuperSU zip file is to be flashed through recovery. When you boot into recovery, select Install, then navigate through the device to find the folder that the file is located. Follow the screen directions to flash items.
USB Debugging needs to be checked for ADB to work, so.....yeah....leave it on.
You don't have to relock your device unless you have to bring it back to the store for repairs. It only stops you from making changes in the bootloader, such as flashing new recoveries, and I think that most fastboot commands might be blocked. I have never tried to use fastboot on a locked device, so I really don't know. Leaving the device unlocked doesn't make it vulnerable or anything, at least to my knowledge.

Thx for your advices AarSyl,
I have successfully root the device and get the Super user app running by following one of tutorial video.
For the first time, when I start at teh bootloader and conduct a "Recovery", it shows a dead robot again but without "no command". I have to redo the fastboot command in the command window with the TWRP recovery file once again. (but this time is very smooth no need to unplug cable that sorts of thing) then I get into the TWRP menu after "Recovery".

Great. I'm happy that it is working for you. A little tip...download Quick Boot from the Play Store. With one touch, you can power off, boot into the bootloader, boot into recovery, or reboot Android.
HELP! "device unauthorized. Please check the confirmation dialog on your device"
I guess that's a ROM problem (indian verison I think), but anyway, I just can't use the phone, it's like the touchscreen stopped working, but when I turn on screen and unlock it (put password) quickly (~3s) I can unlock (everything work), but after this.... no response, but the buttons work (volume, power and home)! So, it's on stock ROM, never was rooted or developer mode was activated, so I can't flash it by QFIL "Download Fail:Sahara Fail:QSaharaServer Fail:Invalid directory name", and at ADB "device unauthorized. Please check the confirmation dialog on your device", I don't know what did I can do now.... Please, help, I don't know which exact model are this one..

To use ADB commands, you need to authorise your computer to issue commends to your device. So, the first time you issue any ADB command to your device, you get a prompt on your device screen and you need to authorise by tapping on "Yes" or "Okay".

Nothing change on device screen when I execute that code..
Hello, I'm having some serious trouble bootloading my Kyocera DuraXV Extreme (AOSP)
I've went into developer options and activated USB debugging and allowed OEM unlocking.
But I get stuck on rebooting into bootloader mode. I've tried different approaches:
1. Starting up phone while holding volume up and down buttons. Then select "reboot to bootloader".
2. adb reboot bootloader command
Both options reboot the phone without going into bootloader mode.
Seems Kyocera decided to somehow lock the bootloader mode. Anyone know of a workaround here?

My comments below are based on the belief that you are trying to unlock the bootloader.
I am not familiar with this phone but generally the two steps mentioned by you are not enough to unlock the bootloader. After those steps, you'll have to issue a command via adb to unlock the bootloader and if successful, then you can boot into it for further operations. The command will vary between devices, so search and profit.
Thanks, this cleared it up a bit, you are right, I'm trying to unlock it.
I'm trying the command fastboot flashing unlock but only getting the message < waiting for any device >. I read somewhere that I might need some USB drivers but I don't know where to find them. I have the latest version of the standard USB drivers for the phone, but as I understand it I need special drivers for this?
I'm trying to follow the steps here: https://www.ifixit.com/Guide/How+to+unlock+the+bootloader+of+an+Android+Phone/152629#s317298
I get stuck on the step:
Enter the command adb reboot bootloader
Wait a couple seconds until your device rebooted into the bootloader, then enter the command fastboot flashing unlock
My phone isn't "rebooted into the bootloader", it just reboots. It gives the message "< waiting for any device >" when I write fastboot flashing unlock

It should be a driver issue. When the phone is on and you connect it to the PC/laptop and send the command 'adb devices', does it show an alphanumeric value? Likewise, when you are booted into the bootloader by key combination and send the command, 'fastboot devices', does it show the same alphanumeric response? If so, the drivers are installed properly. If not, either you don't have the correct drivers or they are not installed properly. Try installing the drivers again after disabling driver signing in Windows on your PC (search for it on Google).
Hello, can you clarify what you mean by "booted into the bootloader by key combination"?
My problem is I cannot boot into bootloader at all.
Any attempt at doing so results in a normal boot of the device.

Are you sure that the key combination for booting into bootloader is what you described in the first post?
1. Starting up phone while holding volume up and down buttons. Then select "reboot to bootloader".

I see Power plus Volume Up as the suggested one from a Google search. Try that.
If you can't even boot into the bootloader with the correct key combination, I don't know how to help you further since we are starting to go in circles. I am sorry.
Hello, thank you so much for trying to help me. It seems I can't boot into bootloader. Volume up + power gives the same result as what I did before.: It opens a "Recovery" menu where I can choose reboot to bootloader, but this option just reboots the phone.
I've been in contact with Kyocera and they say:
Thanks for contacting the Kyocera Customer Support. We will be more than happy to assist you with your concern
In this case allow us to inform you that since this device is a basic phone , it doesn't have the option to activate fastboot mode. By installing something that will change the way the phone works , that will void the warranty that came with the phone. We as manufacture can not help you to modify the software that came with the phone.
So the phone's fastboot mode has been deactivated. But since it's an android I guess it should still be possible with some workaround. I just don't know whee to start, I've been researching for a week with no result.
Something interesting ehre, maybe someone with more coding knowledge can tell what's going on.
I found the source code for the phone and located a file called recovery.c which I guess handles the menu I see when I press volume up + power button. Maybe some clue to why the phone isn't going into fastboot mode?
