Android Firmware Upgrade 1.5 on MacOS

After finally getting a G1 from T-Mobile for testing purposes I quickly realized it is pretty useless if you want to do edge development because you are not allowed to upgrade the latest firmware (at least not straightforward because you need a signed version from T-Mobile). So I ordered an Android Dev Phone 1 which arrived incredibly fast and came in an incredibly unimaginative box that smelled like gummy bears .

After unboxing I started the upgrade process, and as there of course were some minor complications I will outline the detailed steps here.

1. Go to the HTC Page and download the newest Radio and Recovery Image, place them wherever you want just be sure they stay the zip they are meant to be.

2. Connect your Android Phone to your Mac and do not mount the SD Card.

3. Check if your device is connected by using

adb devices

4. Copy the Radio image to the SD Card by using

adb push <radioimagename>.zip /sdcard/update.zip

5. Be sure it is copied by using

adb shell sync

after this is returned everything is done.

The next step is to turn your Phone of by holding down the power button. After its turned of hold down the home button and turn it on again. Some moments after the android sign a ! accompanied by a triangle should appear now your are in recovery mode. Slide out the keyboard and press ALT + L, you now should see the recovery console. Now press ALT + S and you should see some command verifying the package etc… and a progress bar. After that press the Home and Back button (just press do not hold) to reboot the device, note only if you do exactly so the new radio image will be installed. It will display another Image (arrow and a chip) and reboot the system to normal mode after it is done.

Now you are half way through just repeat the steps above with the Recovery Image and you are done
