【原创】移除RX filters在C118上面

11.24.2013, DIY, by .

最近由于一系列安全问题,无意中看到GSM Sniffer的内容,最近也尝试了一把,在这里面最关键的就是更改这个RX 过滤器的事情,没有点专业工具,真是搞不下来,最近又是淘宝,又是电子城的跑,终于花了近500大洋把所有的东西,都买齐了,做这个事呢,不是为了什么,只是喜欢而已。

主要工具:

     热风拆焊台

     小电钻

芯片:

     HHM1526

     HHM1523C1

     04025A150JAT2A

     04025A220JAT2A

辅助器材:

     台灯

     放大镜

     助焊剂

     洗板水

     台钳

学习资料:

     看一下热风枪如何使用

     看一下官方文档

开始

    第一步,把手机的的主板拆下来,拆成下面图片的这种样子,这个是用小电钻把那个屏蔽罩已经去下来的图片

1

这一步是用热风枪把那两个换衡器吹下来,这是吹下来的图片

2

这一步就是把买来了四个元器析焊到上面的成果图片

下面这几张是第二台机器改装的图片,不过都是一样的,只是时间不一样。

这一步当然是试机了,可以看到已经出现uplink的链路数据了

这个更换,真心不好换,搞到零晨几点才焊上了一个,第二个在前面的经验下,三下五除二就焊上去了。

  1. Hi! This is kind of off topic but I need some advice from an established blog. Is it tough to set up your own blog? I’m not very techincal but I can figure things out pretty fast. I’m thinking about creating my own but I’m not sure where to start. Do you have any ideas or suggestions? Thanks| а
