Replacing Built- in CD-rom .iso on mtk devices
First off this has only been tested on my chinese mt6582 chipset phone. (HDC Note 3 N9000)
It came with a build in CD-Rom option when connected to the computer which mounts an iso file that has a single pdf file, this guide will show you how to replace the .iso file with anything of your choosing.
In this tutorial I will be using the following:
- Root Explorer
A rooted mt6582 phone
Damn Small Linux .iso (any .iso should work)
- Start by placing the .iso file on your sdcard
Open Root Explorer and navigate to /system/mobile_toolkit/
In the upper right hand corner tap "Mount R/W"
Copy or move iAmCdRom.iso to your sdcard to have a backup
Move the .iso file you placed on your sdcard to /system/mobile_toolkit/
Rename the .iso file to "iAmCdRom.iso" (spelling has to be exact)
Connect usb to computer
Select to connect as "Build-in CD-rom"
It is as simple as that!
Now when you can use your phone to boot operating systems or you can even create your own ISO that contains drivers for your phone
If your phone is a MediaTek device and has the same file structure and option to mount a CD-Rom it should work - if it does please comment and let me know so I can get a running list of compatible devices
