bootloader unlock on the Nexus S

Excellent news, folks. The bootloader on the Samsung Nexus S (watch our hands-on video) can be unlocked just as the Nexus One's was. Gandalf44 in the Android Central Forums reminds us of the instructions:

  1. Shutdown the phone
  2. Hold down volume up + power
  3. Now you are in the standard recovery mode
  4. Assuming you have 2.3 SDK installed with fastboot (Google around for that info..), now on terminal/windows or Windows cmd depending on OS type "fastboot devices" to check your device can be seem via USB
  5. Assuming you device is seen via fastboot devices, now type "fastboot oem unlock"
  6. Accept ... and new bootloader is unlocked...

Why would you want to unlock the bootloader? You need access to install a custom recovery. And you need a custom recovery to install custom ROMs. And you need custom ROMs because, well, you just do. Trust us. So this is very good news indeed. If we don't see custom ROMs by the end of the day, somebody's slacking. :p More in the Nexus S forums!

May want to point out that it can be locked again via fastboot oem lock. The Nexus One couldn't be relocked.

Has this been confirmed?

Yep, a friend of mine did it last night to his Nexus S.

I notice that this image for the Nexus ONE unlock includes the warranty void message:

Can anyone confirm that also happens in the Nexus S? Or has google wised up to the Magnuson-Moss Warranty Act and deleted this un-enforceable phrase?

They changed the "will" to "may"
