This guide is 5 steps. Please start at the beginning There are 2 other threads for this, but over time the steps have been refined so this new guide gives the same result with minimum effort. For reference the previous 2 guides are here: http://androidforums.com/desire-tips-tricks/160560-force-apps-install-sd-without-root.html http://androidforums.com/desire-tip...ed-device-noobs-guide-updated-09-02-11-a.html Note*** This is for the HTC desire. This should work on most android 2.2+ devices (no 2.1 devices can do this) but you will need your own devices drivers. For HTC devices, HTC Sync provides these. Feel free to ask questions about this process here if you do not have a desire, but other than confirming you have at least Android 2.2, I will not know any more than you do about your device specific issues. 1) download and install htc sync HTC Desire - Application - HTC Sync for all HTC Android Phones (NAM) 2) download sdk and extract to C:\ http://dl.dropbox.com/u/20471345/SUroot/Tools/PC/sdktools-toolsonly.rar Double click the zip file once downloaded and drag the "android-sdk-windows" folder (contained within) to your C: drive *** Note, the provided download is designed to work with this guide. The SDK has changed the path since so if you already downloaded the SDK, you can either keep with that and amend the instructions to reflect your path, or just download the supplied files. 3) Connect your phone by USB (you may need to test with USB and Charge only modes) 4) Open command prompt (in Windows) Go to Start > Run Type "Cmd" and press OK 5) In the black window: Type "cd\android-sdk-windows\tools" and press enter (or platform-tools if you have adb in there) Then Type "adb shell" and press enter Then Type "pm setInstallLocation 2" and press enter Further notes*** This will not move apps that are already installed. It changes the default install location to the SD card so newly installed apps should install to that location. To move apps you already have installed, download "Apps2sd" from the market. This will go through all apps that can be moved and allow you to press the "Move to SD" button for each, sequentially. For some people this will not install apps to the SD card, but still allow those apps to be moved manually. Keep an eye on this. If it doesn't work for you the first time. Try toggling usb debugging to the opposite of what it is currently set to. If it still fails, toggle back again.
