Steps to manually update your G1 to (1.5) Cupcake!

  1. Download the update file
  2. Rename “” to “
  3. Copy to a freshly formatted microSD card (copy it to root)
  4. Reboot and flash your G1 with the new Cupcake firmware
    • Disconnect your T-Mobile G1 from your computer if you used the data cable to access the microSD card
    • Turn off the handset by holding down the “Power” button
    • Turn it back on while holding down the “Power” (End Call) and “Home” buttons
    • When you see “Triangle” icon, open the keyboard and press “Alt” and “L” simultaneously
    • When you see some yellow text, press “Alt” and “S” simultaneously
    • Follow the on-screen instructions
    • Press “Home” and “Back” buttons simultaneously when you’re done and ready to reboot
    • The G1 will reboot as it does its thing - let it do so.
  5. Enjoy Cupcake with on-screen keyboard and stereo Bluetooth support!
