Yes, we can!

“Your time is limited, so don’t waste it living someone else’s life. Don’t be trapped by dogma – which is living with the results of other people’s thinking. Don’t let the noise of other’s opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.”

Play with MOTO Droid 2 Global

Posted on:  February 4, 2012  |   Category: Android, Computer  |   No Comments

I got a MOTO D2G from my friend, but actually this is a broken one, first it cannot be unlocked (band lock), and its camera somehow just won’t work, even after I changed the camera module. So now these two problems seem cannot be fixed, and I just simply use this D2G as a TOUCHPAD for games and surfing the net. Lucky that its WiFi still works fine.

 

(07/02/2012)P.S. Now after a few days’ using, I found that its touch screen is also broken……the right side of the touch screen (about 5mm in width) doesn’t work…… -_-!! (I found a lot of people have the same problem.)

And also, when playing the Need for Speed 13, when using the original rom, it just plays sound and shows a white screen, however under the MIUI rom, the game just won’t run……-_-!!

 

Maybe here I take this chance to warn those who are going to buy or who have already had a D2G, pay attention to your phone, this one seems easily to be damaged.

 

The following are some tips and tools for rooting and changing its ROM, I post them here for your convenience and my future reference.

修改Android版Opera Mini的服务器实现翻墙

Posted on:  August 25, 2010  |   Category: Android, Computer  |   9 Comments

 注:本文所用文本编辑器为UltraEdit。

补充:发现有些同学在改地址的时候有些误解,首先,更改后的地址不要加端口,其次,不要只把your-application-id.appspot.com给写上,还有后面的/opm。如下:

http://your-application-id.appspot.com/opm

socket://your-application-id.appspot.com/opm

 

一、修改Android版Opera Mini 4.2:

 

 1. 先到此处下载并安装JRE:

 http://www.java.com/en/download/index.jsp

2. 点击此处下载我打包的opm4修改包,将其解压至某目录,这里以D盘根目录为例,解压后的目录为:D:\opm4。

 

3. 用文本编辑器打开 D:\opm4\opm\Code.smali ,将 http://server4.operamini.com:80  和  socket://server4.operamini.com:1080  都改成你自己架设的OPM服务器地址,如这篇文章介绍的利用GAE搭建的Opera Mini服务器地址。修改后保存。(用UltraEdit编辑的话,保存后删除自动生成的bak文件,否则一会儿影响编译)

HTC G3 Hero 5键工程机刷Recovery,Radio和ROM

Posted on:  August 24, 2010  |   Category: Android, Computer  |   2 Comments

其实这种教程已经遍地都是了,虽然大多数针对的是G3的上市版机型,但是因为5键工程机和上市机的配置基本一样,所以流程也一样。这篇文章是为了帮助群里的两个兄弟刷机。

1. 安装Android SDK。不过貌似Android的官网被墙了,而且对于只想刷机的同志们,安装SDK有点儿浪费,所以请点击这里下载这个压缩包,解压到任何一个文件夹即可,我这里以 d:\sdk 为例。

2. 到这里下载Recovery-1.6.2,解压出img文件,名字随便命,比如 recovery.img,然后将之拷入SD卡。(工程机用户请勿下载1.7版RA,刷后无法进入RA,3键用户似乎也用不了1.6.2,请使用以前的版本)

3. 到这里下载Radio,下载完后不用解包,直接将zip文件命名为radio.zip,放入SD卡根目录。要想顺便刷ROM的话,也把ROM的zip文件拷贝到SD卡根目录,命名为rom.zip。(名字都是可以随便命的)

4. 打开命令行,进入 d:\sdk。

5. 按下图命令执行:(在执行下述命令前,手机不要处于“装载”状态)

6. 如果上述过程执行无误,关机,按 小房子+开机 键开机,即可进入Recovery界面了。

7. 再下一步,无论是刷Radio还是rom,进入recovery后选择Flash zip from sdcard即可,下一个界面里会列出所有的zip文件,所以不必非得命名成“update.zip”。

8. 最后,在5键工程机的recovery界面里,音量键是上下,拨号键是确定;此刷机过程也可以用手机上的超级终端来完成,方法与本文类似,若遇到问题请自行Google。

若有需要,也请同时参见我另一篇博文:http://www.p4cpu.net/2010/08/04/openvpn-on-htc-g3-hero/

在HTC G3 Hero上配置OpenVPN

Posted on:  August 4, 2010  |   Category: Android, Computer  |   2 Comments

前阵子从小毛球手里买到了一个HTC G3 Hero的工程样机,此机器与零售版的Hero略有不同,它没有轨迹球,ROM和RAM的容量也比零售版要小,并且只支持Android1.5版的ROM,俗称“5键版”(还有一种工程机为3键版)。

好了,回归正题。我的设备,只要是能联网的,都免不了要为其添加翻墙的功能。起初在网上看到很多朋友是下载了各种必须的文件之后,通过命令行一步步手动执行的,可是我执行了多次都没能奏效,可能是手机系统的个体差异,再加上我对Android命令行操作也不太了解,所以最总没有成功。后来搜到一个可以直接通过软件安装的方法,再借助xda-developers论坛和android-openvpn-installer项目里外国大牛们的指点,最后成功解决,下面是详细的步骤:

我的ROM版本是:3.2-update-hero-modacocustomrom-core-signed.zip (1.5固件)

Recovery 版本是: Recovery-RA-hero-v1.6.2-blue
