Nexus 7 2013 - Root Failed
Hi, I am a Nexus 7 user and was tried to root my device using the Toolkit v1.8.2I 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. I use same toolkit for my n7-1st gen last year, also no start up, fortune within warranty, so they change motherboard for me {:9_404:} 有冇試過用大陸出既卓大師一鍵ROOT? Thx for all ching reply.
I get help from some guys in xda.
now teh machine is recovered and started up brand new.
Now still need to think again if I want to "root" it again!

多謝板主加分。
其實之前去過先達揾幇手。得一間用部腦抄咗20分鐘.
吾得後放棄.連個芒都冇望過一分鐘！
諗著去二樓間"億x" 見本雜誌成日講，以為勁D
問個CF, 仲要俾佢寸話" Nexus 都敢root 機，即係自尋死路！冇得整！"
又係望都冇望部機一眼.
俾佢嚇到以為真係死緊！
點知D高手睇完我寫D過程，就話冇有怕。
攪掟。一
