【失败】华为Mate2 使用LEAP WIFI

试了半天，终于替换了网上说的wpa_supplicant，但是还是不行。。。 刚买了华为的Mate2，结果发现上不了公司的Leap Wifi了。 搜到几个有用的页面： 1. http://blog.csdn.net/quqi99/article/details/17144869 这个基本上就可以解决问题了。 其中提到了google

这个基本上就可以解决问题了。

其中提到了google的这个bug，里面可以下那个wpa_supplicant.

其中有一个回复我觉得这个方法会更方便点。

Hurray!  LEAP is working on my 4.2 Nexus 7!

I am running the 4.1.2 wpa_supplicant executable on my otherwise stock 4.2 system.  

Here are the instructions for the steps I went through to do this:

Step 1:  Get a copy of the proper 4.1 wpa_supplicant executable for your device.

  My approach: download factory image
    If you have a Nexus device, use this page: 
      https://developers.google.com/android/nexus/images
  Un-tar image
  Use unzip to extract file "system.img" from image-xxxxxx.zip
  Use expand script (simg2img) to expand the system.img file, creating tmp.img file.  Script is found here: 
    http://usefulshellscript.googlecode.com/svn/trunk/simg2img.py  
  Mount tmp.img file using this command (as root): 
    mount -t ext4 -o loop tmp.img /mnt (or the mount point of your choice)
  Copy wpa_supplicant executable from the bin subdirectory, for example:
    cp -p /mnt/bin/wpa_supplicant ./wpa_supplicant-4.1.2
  Unmount the image file and clean up the gigabytes of files you've created during this process

Step 2:  Transfer the file to your Android device (I used WiFi File Explorer, but do whatever works for you)

3.  Install the 4.1 version of wpa_supplicant 
    (commands assume the new version is in the Download directory - modify as needed)

  On your device, open a terminal session, become root
  Make the /system directory writeable: 
    mount -o rw,remount /system
  Copy your new file there: 
    cp -p /sdcard/Download/wpa_supplicant-4.1.2 /system/bin
  Make it executable: 
    chmod 775 /system/bin/wpa_supplicant-4.1.2
  Rename the old version: 
    mv /system/bin/wpa_supplicant /system/bin/wpa_supplicant-4.2
  Create a link to the new version (makes it clear which version you're running): 
    ln -s /system/bin/wpa_supplicant-4.1.2 /system/bin/wpa_supplicant
  Verify this all worked: 
    /system/bin/wpa_supplicant -v
  - should return version 4.1.2
  Restart your system and LEAP should work as in 4.1.x

还没最后实验成功，期待能用。
