Last year I got a free Android phone at a Google event, and I would like to upgrade it to the latest Android version (probably with Cyanogen).

What is the quickest/safest way to do the upgrade?

It is a developer phone, so:

HTC Magic, Model Number GDDJ-09, Build CDB56, Android 1.5, details:

HBOOT-1.33.3005 (SAPP20000)

  • I believe this isn't possible because that phone doesn't have enough memory or something like that. Android has gotten a lot bigger since 1.5 . I'm not putting this as an answer because I'm not 100% sure – WalterJ89 Oct 28 '10 at 14:46
  • @Walter Cyanogen managed it, he's basically magic ;) – FoleyIsGood Nov 19 '10 at 13:47
  • The workaround for "data plan required" is only for the G1 - you can't enable USB Debugging on the Magic without activating the handset. – Broam Aug 4 '11 at 21:32

This section of the Cyanogen instructions seems to cover the developer Sapphire handsets


Unfortunately Cyanogen have not build 2.3-Gingerbread yet but you can get Gingerbread on the MAGIC through Ginger Yoshi. Details on XDA: http://forum.xda-developers.com/showthread.php?t=932118

  • Nice. I will try it on my veteran Google Ion, currently stuck on Android 1.6, and recently banned from the Android market / Google play store. – jap1968 Jul 10 '12 at 9:16
