how to unlock and install superuser (su) on android without breaking OTA updates


Phone that allows unlocking ie: N1, NS etc

You will need to first install the android sdk for your pc which can be found here:


This should come with fastboot but if you are on osx fastboot-mac can be found here:
fastboot-mac.zip (Fastboot for mac)

Download a custom recovery for your phone. This site seems to have a decent http://www.clockworkmod.com/recovery_images.html
If not try googling for recovery that will work with your phone model.

Download SU for your phone here:

How To Do IT

Copy the custom recovery .img and su.zip files to the SDCard in your phone

Connect your phone via USB and put it into fastboot mode. reboot phone and hold volume down and power. If this doesn’t work try googling for “phonemodel how to get to fastboot or recovery”

once in fastboot mode on your pc enter the commands:


This will unlock your phone. Accept the onscreen prompt.

fastboot oem unlock


Temporarily boot your custom recovery image

fastboot boot customrecovery.img

In your custom recovery use the menu option to flash the SU.zip file from your SD card.

Now reboot your phone.

Your phone is now unlocked and able to run applications in super user mode!

Get super user elite. If u have trouble finding any file online google "expressfiles" it has its own search and download engine

Once in recovery if you get error. Back up files and do factory reset. Install super user after installing custom recovery.img like clockwork mod. Have usb debugging enabled also.

Thanks for letting me know Amanda. I updated the links to for fastboot mac and for recovery images as they were broken.

HTC seems to have updated their page and the file is no longer available for fastboot :-(
