Here is the tutorial of getting root access on Amazon Kindle Fire.
Before getting access on Amazon Kindle Fire, you need to prepare 4 tools:
Ⅱ: The related drive of Amazon Kindle Fire
The first step is to install USB drive:
Firstly, let’s come into this step. Find Setting-Application program-USB debugger button, then check the first option. Next, connect your USB line with PC, it will prompt you to install driver. If it is the 32 bit system, then you are supposed to choose “x86” document to install the drive. Whereas, if it is 64 bit system, choose “amd64” document to install the drive.
The second step is to prepare the software for Amazon Kindle Fire:
In detail, remove the “TMG” document in your software kit to the root directory in C disk, in order to give us the convenience of finding C:\TMG\
The third step is to examine adb.exe and fastboot.exe:
To begin with the third procedure, all we need to do is to ensure that we have the document of adb.exe and fastboot.exe in TMG. So we need to accomplish those procedures one by one.
The fourth step is to check the condition of drive installation:
Unplug your USB line, then shut down Amazon Kindle Fire, next press the backspace key. Go on pressing the power key to enter bootloader. Then connect Amazon Kindle Fire with PC, and fastbootusb will come out in Amazon Kindle Fire. Pay more attention that never press mount at this time.
Open Start-Run-CMD, then enter the order: cdC:\TMG
C:\TMG>_ will come out when the order runs successfully.
Then input the order: fastboot devices.
The fifth step is to start rooting:
Enter: fastboot boot cm-hero-recovery.img after C:\TMG>. Then Amazon Kindle Fire will enter the mode of recovery.
We will see seven options in this mode, they are the following ones:
[Home+Back]reboot system now\\restart
[Alt+S]apply sdcard:update.zip\\install update.zip in SD
[Alt+A]apply any zip fromsd\\install any zip file in SD
[Alt+W]wipe data /factoryreset\\delete all datas
[Alt+B]nandroid v2.2 backup\\back up
[Alt+R]restore late stbackup\\recover the final back-ups
[Alt+F]repair ext filesystems\\suggest backing up ROM in Amazon Kindle Fire, use the trackball to move the cursor to [Alt+B]nandroidv2.2backup, check it. If there is something wrong with your Amazon Kindle Fire, it can also recover.
Now start entering the order, an order is in a line. Pay attention to the small letters and the big letters and also the blank.
adb shell mount /system
adb push su /system/bin/
adb shell chmod 4755 /system/bin/su
adb push Superuser.apk /system/app/
adb shell reboot
After rebooting, you will finally get root access on Amazon Kindle Fire.
