T-Mobile G1 owners have been patiently waiting for T-Mobile to roll-out the Android OS 1.5 update, known as “Cupcake,” through over-the-air installations. Alas, we’ll all be waiting until at least next month before T-Mo gets the eagerly-anticipated Android OS 1.5 “Cupcake” update to the entire US. But, that doesn’t mean you have to wait on T-Mobile to get your hands on the new Android OS. The Android OS 1.5 ROM is now available through the Android Code website as a free download – and with a little elbow-grease, anyone can force-update their G1 without T-Mobile’s help.
With video-recording, homescreen widget support, stereo bluetooth and an on-screen keyboard, the Android Cupcake update is worth getting your hands on. For those of you already familiar with force-updating your G1, go ahead and do your thing (the steps are the same as we’ve outlined previously). Follow these instructions to force-update your G1 to Android OS 1.5 “Cupcake” -
- Download the signed-kila-ota-xxxx.xxxx.zip update file
- Rename “signed-kila-ota-xxxx.xxxx.zip” to “update.zip”
- Copy update.zip to a freshly formatted microSD card (copy it to root)
- 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.
- Enjoy Cupcake with on-screen keyboard and stereo Bluetooth support!
