How to Install CyanogenMod on the Amazon Kindle Fire (2nd Gen) ("otter2")
This guide will walk you through the process of taking the Kindle Fire (2nd Gen) from stock to having a custom recovery image and the ability to flash the latest version of CyanogenMod.
Modifying or replacing your device's software may void your device's warranty, lead to data loss, hair loss, financial loss, privacy loss, security breaches, or other damage, and therefore must be done entirely at your own risk. No one affiliated with the CyanogenMod project is responsible for your actions. Good luck.
The 2nd-generation Kindle Fire has a locked bootloader. You must install a 2nd-bootloader for custom recovery support.
One-Time Install of Amazon 2nd-Bootloader Exploit
THIS IS A ONE TIME INSTALLATION TO ENABLE CUSTOM RECOVERY / ROMS
These instructions are for the Kindle Fire 2nd Ed.(otter2) / Kindle Fire HD 7" (2012)(tate) and Kindle Fire HD 8.9" (jem) devices only!
Step 1: Test your fastboot driver installation by doing the following:
(For Kindle Fire 2nd Ed. and Kindle Fire HD 7" (2012) a fastboot cable is needed for this procedure. This cable is a special USB cable with a powered pin that normal USB cables do not have. For the Kindle Fire HD 8.9" it is not required.)
- Power down your device if necessary
- Type the following command into a cmd/terminal window on your PC:
fastboot -i 0x1949 getvar product
- Should return with:
< waiting for device >
- If you need to, connect your fastboot cable to the Kindle at this time
- Reboot the device
- It *SHOULD* show a Fastboot screen and your terminal window should show something like:
If you have any problems with these initial steps try downloading Amazon's USB drivers for the Kindles and then repeat the above till you see the desired response.
Step 2: Download the files you will need to install 2nd-bootloader & TWRP recovery:
- An older bootloader with an unlock exploit (this is specific to your device):
VERY IMPORTANT THAT YOU DOUBLE CHECK THE MD5SUM ON THIS FILE. IF ITS CORRUPTED AND YOU APPLY WITH FASTBOOT, YOUR DEVICE IS A BRICK.
- TWRP Recovery:
- Freedom Boot.img:
Step 3: Use fastboot to apply exploit files and reboot into recovery With the device powered off: connect your FASTBOOT USB cable(if needed) to the Kindle which should cause it to power on and enter "FASTBOOT" mode. Issue the following commands into your command/terminal window on your PC 1 at a time. (if you don't need a fastboot cable then power on the device after entering the 1st command below)
fastboot -i 0x1949 flash bootloader otter2-u-boot-prod-10.2.4.bin
fastboot -i 0x1949 flash recovery otter2-twrp-220.127.116.11-recovery.img
fastboot -i 0x1949 flash boot otter2-freedom-boot-10.4.6.img
- (if using a fastboot USB cable swap to a normal USB cable before entering the next command)
fastboot -i 0x1949 oem recovery
If all has gone well, then your device should now be in recovery. (No need to do step #4 below in the installation process)
Installing CyanogenMod from recovery
- Make sure your computer has working adb.
- Download the CyanogenMod package for your device that you'd like to install to your computer.
- Optional: Download 3rd party applications packages, like Google Apps which are necessary to download apps from Google Play.
- Place the CyanogenMod
.zippackage, as well as any optional
.zippackages, on the root of
- Using adb:
adb push filename.zip /sdcard/
- Note: You can copy the
.zippackages to your device using any method you are familiar with. The
adbmethod is used here because it is universal across all devices and works in both Android and recovery mode. If you are in recovery mode, you may need to ensure
/sdcard(sometimes called Internal Storage) is mounted by checking its status in the Mounts menu. If you have booted regularly, USB debugging must be enabled.
- Using adb:
- If you are not already in recovery, boot to recovery mode now.
- During bootloader splash screen (blue Kindle logo), press Power repeatedly to open boot menu and move selection from Normal Boot to Recovery.
- In Team Win Recovery Project, select menu choices by tapping on the appropriately labelled button.
- Optional (Recommended): Select the Backup button to create a backup.
- Select Wipe and then Factory Reset.
- Select Install (if you're running Cyanogen recovery this is Apply Update).
- Navigate to
/sdcardand select the CyanogenMod
- Follow the on-screen notices to install the package.
- Optional: Install any additional packages you wish using the same method (if you are installing multiple packages, install CyanogenMod first and then install any subsequent packages on top of it).
- Once installation has finished, return to the main menu and select Reboot, then System. The device will now boot into CyanogenMod.
