Upgrade from JF 1.5 (Cupcake) to Cyanogen 1.5 (Cupcake + a taste of Donut)

CyanogenMod is a rapidly evolving build of Android for the HTC Dream (T-Mobile G1) and HTC Magic (T-Mobile myTouch) phones. If you’re running a stock T-Mobile phone but had already rooted it and installed JF’s 1.5 build, here’s the quick upgrade path to Cyanogen.

Fast upgrade instructions:

  1. Download the latest update-cm-*-signed.zip
  2. Rename it to update.zip
  3. Copy it to the root directory of your phone’s SD card
  4. Turn your phone off
  5. Turn it back on while holding the Home key
  6. Once the recovery mode finishes booting (There should be a yellow warning sign displayed and perhaps a menu) – hit alt-s and wait for it to install
  7. Home + Backspace to reboot to Cyanogen

Cyanogen has a handy updater app that works like the JF one, but you’ll need to install a new recovery firmware for it to work.
