Rooting Intel Android Devices on Linux/Mac OS X
In this article I will explain how to root Intel-CPU based android Devices on Linux/Mac OS X. The instructions are based on this forum post. I used this code to root a Medion LIFETAB P8912. However this should also apply to all devices mentioned in this forum post.
The first thing to do, is install fastboot and adb on your PC/Mac. Make sure that you have enabled the development option on your android device and are able to connect to it via adb.
Then place the update, you want to install on the sdcard on your device. In case you want to install the root patch, you can download the latest SuperSU. Note that you will be not able to install custom roms, if your bootloader is locked. If the signature missmatch it will refuse to boot.
The next thing to do is to download and extract IntelAndroid-FBRL-07-24-2015.7z mentioned in the post. It contains a recovery images for CWM or TWRP and some custom trigger code to start a temporary CWM Recovery Session on the device. After reboot this session will be gone. But you can apply updates during the session such as SuperSU. You will not be able to follow the exact instructions from this forum post, because it contains a windows specific batch file and windows executables. However these are just fancy wrappers around adb and fastboot, so you can still use the contained images/launch code.
To reboot your device into the bootloader, connect it to your computer and run, while it is turned on:
Within the boot loader, we will first put the alternate rescue image on the device along with some custom launcher code. I first tried TWRP on my device, but my touchscreen didn’t work with it, so I sticked to CWM:
1 2 3
The next thing to do is to trigger the device via fastboot to start our recovery. The forum post contained 4 alternatives approaches based on the android device. The following (T4) was working for me:
This temporary replace logcat with a launcher. It is important to execute all commands in one shot. Otherwise fastboot will fail to flash logcat.
If the command will not work for you, you could one of these commands:
1 2 3 4 5 6
If everything works it should start the recovery image.
