Unlocked --- Now What?


android, clockworkmod, htc [link] [comments ()] [raw]

As explained in an earlier post, the HTC Wildfire (Buzz) that has been my phone for a few years has been "bootloader unlocked" using the facility provided by HTC at their site for developers. Note that this is not the same as "S-OFF". The phone is still "S-ON" so some sort of "security" (as determined by the manufacturer!) is still "on". As seen below this does not prevent us from installing "Clockworkmod Recovery" which is a useful tool.

Note that this does not change the "normal" functionality of the phone. It merely prepares the phone for "non-standard" usage by replacing the "recovery" image.

First of all one needs the "Clockworkmod" image. The possible images can be seen on the ROM Manager homepage. My phone, the HTC Wildfire (Buzz) is listed as "Buzz" with the Clockworkmod recovery version 5.0.2.0. Unfortunately, the file for the image on that page is wrong. The correct file is recovery-clockwork-5.0.2.0-buzz.img. This can be downloaded by a simple

wget http://download2.clockworkmod.com/recoveries/recovery-clockwork-5.0.2.0-buzz.zip

Now that we have the image, it has to be flashed.

Note that this will erase the existing recovery image so the potential for "brick"ing is ever present! I was impatient and did not backup the recovery image. Perhaps a more cautious approach would be to install the "su" binary and then use an application like "ROM Manager" to backup the recovery first. Luckily, it all worked for me!

The phone has to be rebooted into "fastboot usb" mode. This can be done by connecting the USB cable and running 'adb reboot bootloader'. (It may be worth reading the earlier post to figure out the different states of the bootloader if you get error messages.) After this the procedure is simple

fastboot flash recovery recovery-clockwork-5.0.2.0-buzz.img

Once it completes, reboot the phone and disconnect the USB.

To get a hang of using "ClockworkMod", reboot to the bootloader in "fastboot" mode and highlight "recovery" with the Volume Button. Now press the power button once to run recovery. You should see the "clockworkmod" screen. The buttons work as follows:

The first thing to do is to run the "backup" from clockworkmod and backup your current state of the phone to (micro) SD card. It is probably a good idea to copy this from the SD card to your laptop in a safe location.
