好久以前的機器了，只有512M內存，簡直是閑，花了一天的時間刷成了cm12（cm14內存占用略大），主是參考xda大神的帖子（附在文末）
本文搬自xda，文末附有原帖地址，以及部分文件。
本人原先刷過twrp for otter，以及cm11，在此基礎上刷的cm14.
1、直接mout sd卡，用電腦將bootloder文件轉入手機，然后install OtterX Bootloader，文件百度地址otterx-u-boot_v2.05.zip
2、同理刷入twrp for otterx
3、Reboot after installing TWRP for OtterX
Open the bootloader menu by pressing [POWER]
Use 1-2 SHORT presses of [POWER] to highlight "ADVANCED -->"
Use a LONG press of [POWER] to select ADVANCED MENU
Use 5 SHORT presses of [POWER] to highlight "PARTITION MODE: AMAZON" (if this is OTTERX you can skip step 3)
LONG press [POWER] to open "PARTITION MODE MENU"
Use 4 SHORT presses of [POWER] to highlight "[CONFIRM] SET MODE: OTTERX"
WARNING THIS WILL ERASE THE CONTENTS OF YOUR "SDCARD" and USERDATA!!!! Before doing this step you should have backed up ANYTHING IMPORTANT and pulled it off of your Kindle!
LONG press will select this option and your system, cache, userdata will be changed to the OtterX layout (and ERASED)
Now use short [POWER] presses to navigate BACK and then to "RECOVERY"
4、此時可以通過ADB push命令，將刷機包移入平板
adb push <rom.zip filename> /sdcard/
adb push gapps-kk-20140105-signed.zip /sdcard/gapps-kk-20140105-signed.zip
5、如需谷歌服務，可以此時刷入gapps zip包（不刷入gapps，可能卡在歡迎界面，需要刪除system/pri-app/cmsetupwaized文件夾（需先mount system））
6、重啟，出現開機畫面，需要等待5分鐘左右進入系統。
4、5、6步驟可以刷入各個版本的刷機包。
機子還是太老了，運存太小了，愛折騰的權當弄得玩吧，可以體驗一下，cm的各種版本（基于安卓5、6、7）
