Was having a very difficult time trying to Superuser this android tablet (kylin MID android 2.2), but finally got it working. Here’s how:
From this site:
The instructions:
Whats needed
Set up the SDK-ADB for instructions on setting up adb see this video by unlockr
You need to be able to get to your phone via a USB cable.
Rageagainstthecage – download this.
1.) Enable usb debugging if you dont already have it enabled
2.) Extract rageagainstthecage.zip to c:\droidroot
3.) Connect your phone to the computer via usb cable
4.) on the computer open the command prompt. (In the start menu under accessories)
5.) cd to your adb tools directory. For most the command would look like this cd C:\android-sdk-windows\tools
6.) adb devices (This should list a device as a long number under list of devices. If it doesnt something is wrong.)
7.) adb push c:\droidroot\rageagainstthecage-arm5.bin /data/local/tmp
8.) adb shell
9.) cd /data/local/tmp
10.) chmod 0755 rageagainstthecage-arm5.bin
11.) ./rageagainstthecage-arm5.bin (This can take a minutes just let it go until you are returned to your adb tools folder)
12.) adb devices
13.) adb shell (you should now see a # instead of a $)
14.) mount -o remount,rw -t [NAMEOFDEVICE] /dev/block/mtdblock4 /system
15.) exit
16.) adb push c:\droidroot\Superuser.apk /system/app
17.) adb push c:\droidroot\su /system/bin (<– this is where I had to change it to xbin instead of bin)
18.) adb push c:\droidroot\busybox /system/bin (<– change this one as well to xbin)
19.) adb shell
20.) chmod 4755 /system/bin/su (<–another change to xbin)
21.) chmod 4755 /system/bin/busybox (<–and the last change to xbin)
22.) mv /system/recovery-from-boot.p /system/recovery-from-boot.p.disabled Note if you are on a build earlier than froyo this step will fail. That is fine and expected.
23.) mount -o ro,remount -t [NAMEOFDEVICE] /dev/block/mtdblock4 /system
24.) rm /data/local/tmp/rageagainstthecage-arm5.bin
25.) exit
I would suggest rebooting your phone but its not required.
Install Terminal Emulator from the Market, type
su
then hit enter and it will let you know if you have superuser access.
