第一步:取得tattoo的root权限
具体过程参考http://forum.xda-developers.com/showthread.php?t=635961
第二步:更改环境变量
export LD_LIBRARY_PATH=/system/lib
export PATH=$PATH:/system/bin:/data/local/bin:/data/busybox
第三步:加载tattoo-hack.ko,重新挂在system
insmod /data/local/bin/tattoo-hack.ko
mount -o rw,remount /dev/block/mtdblock3 /system
第四步:修改tiwlan.ini
Code:
adb pull /system/etc/wifi/tiwlan.ini .
This will copy the file from the device to the computer. In Linux the file will be stored in the user’s home directory. I am not sure where it will be stored in Windows (search for it if you can’t find it). Open the file in a text editor. Locate the text “WiFiAdhoc = 0″ and change the 0 to 1. Then we will place two new lines right underneath it, to make it look like this:
Code:
WiFiAdhoc = 1
dot11DesiredSSID = InsertyourSSIDhere
dot11DesiredBSSType = 0
Replace InsertyourSSIDhere with the name/SSID of your planned ad-hoc network. We are finished with this file for now, so save and close the file.
In the terminal, type:
Code:
adb pull /data/misc/wifi/wpa_supplicant.conf .
Wpa_supplicant.conf is the tool we use to configure the network security. Open the file in the text editor. I have my file configured like this:
Code:
ctrl_interface=tiwlan0
update_config=1
eapol_version=2
ap_scan=2
fast_reauth=1
network={
ssid="InsertyourSSIDhere"
scan_ssid=0
mode=1
key_mgmt=NONE
# group=WEP104
# auth_alg=SHARED
# wep_key0="InsertyourownPASSKEYhere"
}
Once you are happy with your configuration, save and close the file.
第五步:将文件放回tattoo
先将tiwlan.ini和wpa_spplicant.conf通过adb放回sdcard中
adb push tiwlan.ini /sdcard
adb push wpa_supplicant.conf
然后通过busybox的cp指令copy到/system分区
export PATH=$PATH:/data/busybox:/data/local/bin
cp /sdcard/tiwlan.ini /system/etc/wifi/
cp /sdcard/wpa_supplicant.conf /data/misc/wifi/
注意在/system/etc/wifi/中也有个wpa_supplicant.conf,但是修改覆盖这个文件没有用。
然后,重启手机 就可以看到wifi有ad-hoc网络了,
但是wifi的IP地址还不知道怎么设置,现在使用的是DHCP方式获取IP。
现在我的tattoo已经可以通过笔记本共享上网了
