Droid 2 Global 的FM收音機 求助刷機達人

小弟發現D2G原生沒有FM收音機，爬了XDA後才發現有人將Droid X的收音機拉了出來給D2G用，

但是小弟看了很久實在看不懂這個教學，板上有大大可以提供小弟一點協助嗎?

以下是XDA上的教學，小弟畫紅字的就是看不懂的部份，請大大給予指教

1. Droid2 must be rooted. Remount the /system to RW

2. Unzip the archive, and use abd push to put the files in the appropriate folders.
cd system

a. adb push app/FMRadio.apk /system/app
b. adb push app/FMRadioService.apk /system/app
c. adb push bin/fmradioserver /system/bin
d. adb push lib/libFMRadio.so /system/lib
e. adb push lib/libfmradio_jni.so /system/lib
f. adb push lib/libfmradioplayer.so /system/lib

3. Remount /system to ro
4. Plug in headphones.
5. Run FMradio
