How to manually install the official T-Mobile Android 1.6 on your G1

T-Mobile has started sending out Android 1.6 to its customers in an over the air update. The rollout is staggered and occurring over several weeks. You can stare at your phone endlessly waiting for the download or you can manually download it yourself.

We have discovered the file for the T-Mobile G1 which updates your phone to Android 1.6. This file is being hosted by Google so I don’t think anyone will complain about distributing it.

For the full list of Android 1.6 highlights, visit the official Google Android site.

If you have a T-Mobile myTouch 3G, please be patient while we wait for the download link to be discovered.

Method A – My G1 has the official T-Mobile version of Android 1.5

Read first: This method is for people running an official T-Mobile USA version of Android. You will be downloading the official update file from Google and manually installing it on your phone. The update file is the exact file that is being sent to phones over the air, but this method allows you to manually download it (instead of sitting there waiting).

Warning: Some developers have not updated their apps to be compatible with Android 1.6 yet. Check your favorite apps to make sure they have been updated and contact the developer if they have not.

Warning 2: If you have a home replacement app that does not support Android 1.6 you may get stuck in a force close loop. You can boot into safe mode and uninstall the offending app. Hold down Power+Menu when turning on the phone and keep holding down both buttons until the phone boots in safe mode. You can then go to Settings > Manage applications to uninstall the app.

  1. Download T-Mobile Android 1.6 (DRC83) from Google. (Search Google for “signed-kila-DRC83-from-CRC1.c41b93c1.zip” if the link is removed)
  2. Copy the downloaded file to your phone’s SD card. (Advanced users only: Use the command “adb push signed-kila-DRC83-from-CRC1.c41b93c1.zip /sdcard/update.zip”)
  3. Rename the downloaded file to update.zip (Make sure you can see the file extension. Many users make the mistake of naming the file update.zip.zip)
  4. Reboot your phone into recovery mode. Power off the phone first and then hold down the Home key while powering it back on.
  5. The recovery mode is finished loading when you see the ! mark inside the triangle. Press Alt+L  to display the list of options.
  6. Press Alt+S to flash the file update.zip.
  7. Wait for the update to apply. Your phone may reboot during this process so be patient.
  8. Press Home+Back if prompted to reboot your phone.

Verify: When the update is complete you can double-check your version of Android by going to Settings > About phone.

The build number should read DRC83.

Method B – My G1 has a hacked version of Android currently installed

Read first: This method is for people running any hacked version of Android. Installing the official T-Mobile version of Android 1.6 will wipe your phone and you will lose root access. This is for people who wish to return to the latest default install of Android.

Warning: Some developers have not updated their apps to be compatible with Android 1.6 yet. Check your favorite apps to make sure they have been updated and contact the developer if they have not.

Step 1: Downgrade to RC29

  • Download the file DREAIMG-RC29.zip (Search Google if this link is removed)
  • Unzip the file DREAIMG.nbh and copy it to your SD card home directory.
  • Power off your phone first and then hold down the camera button while powering it back on.
  • When prompted, press the power button to begin the downgrade. Wait for it to finish and display the rainbow screen. Press Talk+Menu+Power to reboot your phone (or just pop your battery out once the downgrade has finished)

Step 2: Upgrade to Android 1.5 CRB43

  • Download the file signed-kila-ota-148830.de6a94ca.zip (Search Google if this link is removed)
  • Rename the file to update.zip and copy it to your SD card (Advanced users only: Use the command “adb push signed-kila-ota-148830.de6a94ca.zip /sdcard/update.zip”)
  • Reboot your phone into recovery mode. Power off the phone first and then hold down the Home key while powering it back on.
  • The recovery mode is finished loading when you see the ! mark inside the triangle. Press Alt+L  to display the list of options.
  • Press Alt+S to flash the file update.zip.
  • Wait for the update to apply. Your phone may reboot during this process so be patient.
  • Press Home+Back if prompted to reboot your phone.

Step 3: Upgrade to Android 1.5 CRC1

Step 4: Upgrade to Android 1.6 DRC83
