Replace Virtual CD on the HTC EVO 4G LTE

Every now and then, a mod so unique pops up that it bears closer examination. For HTC EVO 4G LTE owners, a mod such as this has appeared. When booted into a Sense ROM and connected to a PC, one will notice that the device mounts as two drives. One is the internal storage, and the other is a CD-ROM. Yes, a CD-ROM. Naturally, upon discovering this, the first step is to see if it can be used for something else. As it turns out, it can be.

XDA Recognized Contributor closeone has discovered that there is a file on the EVO LTE called PCTOOL.ISO, which is what causes the EVO LTE to show up as a CD-ROM when it’s plugged into a PC. Closeone explains why it is there and what can be done about it:

There is a file named PCTOOL.ISO inside the /system/etc directory that normally contains the HTC Sync Manager Software. By replacing that ISO with another, it’ll mount that one instead. Because there isn’t too much room to spare in the /system partition, the file should probably be kept relatively small.

There are a number of things users can put in place of the HTC Sync Manager Software, although not a whole lot of things have been tested yet. In theory, though, quite a few useful tools can be placed here, as closeone says:

1. ROM Developers can include a package that contains a copy of the ADB and Fastboot executables within their ROM. ADB would be useful while the device is on; Fastboot would probably have to be copied to the computer.
2. Because the ISO is mounted as Read-Only media, it could be incredibly useful for field technicians who need to run portable software, without the risk of being infected with a virus on the host machine.

Being able to run portable software without thread of virus is definitely something anyone could benefit from. Aside from being one of the more unique mods on XDA, having functionality like this on the EVO LTE can lead to various possibilities.
