It’s been a year since the HTC Inspire 4G was released. Back then, it was powered by Android 2.2 Froyo that was later on upgraded to Android 2.3 Gingerbread. Still, we know a lot of you out there would crave to upgrade your phone’s firmware to Android Ice Cream Sandwich. You’re quite lucky though. In this post, we will teach you how to upgrade your handset to Android 4.0.3. But before anything else, keep in mind that this is not the official firmware and you might encounter a couple of bugs and errors.
Also, we recommend you to create a backup of your important files, messages, call logs and contacts. You would also need to enable your phone’s USB Debugging mode. To do this, simply go to Settings > Applications > Development then check the box next to the USB Debugging option. To prevent your phone from shutting off while in the middle of installation, ensure that your handset’s battery won’t go any lower than 60 percent. If you’re all set, read on.
Step 1: Download the Android 4.0.3 ICS Firmware for your HTC Inspire 4G at this link. Save the file to your computer then connect your phone to your computer using a USB data cable. Copy the file to your phone’s SD card. After that, disconnect your phone from your computer.
Step 2: Turn off your handset then reboot to recovery mode. You can do this by pressing the Volume Up key while holding the OK and Power buttons. Select ‘recovery’ from the list of options.
Step 3: In recovery mode, select ‘install zip from sd card’ then ‘choose zip from sd card’. Locate and select the file that you have downloaded from step one. Wait until the file gets fully installed. Repeat this step for the Google Apps Package.
Step 4: Once done, your phone will automatically restart. Select ‘++++ Go Back ++++’ then choose ‘reboot system now’ to reboot your phone.
Step 5: Check your phone’s firmware version by going to Settings > About Phone > Firmware Version. You will then know if you have successfully installed the Android 4.0.3 ICS Firmware on your HTC Inspire 4G phone.
