Android devices, however well-made, have acquired a bland taste when Android 4.0 Ice Cream Sandwich arrived. Eclair, Froyo, Gingerbread, and Honeycomb have all taken second place when Ice Cream Sandwich reared its delicious head.  That is why many users of Android devices are longing to have Ice Cream Sandwich on their devices–including users of the powerful, Honeycomb-run tablet, the HTC Jetstream.

There are several custom ROMs for the HTC Jetstream, and it won’t be long before a stable ICS ROM arrives on it.  But, you can only enjoy those custom ROMs on your Jetstream if you have rooted your Android tablet.  Unfortunately, rooting your Android tablet will also void its warranty.  That’s the price you have to pay for the power to completely own and control your Android tablet.

If a voided warranty is a small price to pay for freedom for your tablet, go ahead and root your Jetstream.  You’ll find the rooting instructions in the rest of this guide.

Requirements

• HTC Jetstream with an unlocked bootloader. You can unlock your device using HTC’s official booloader unlock tool here.
• ADB with Fastboot installed on your computer. See our guide about ADB and how to install it on your computer.
• Download the following files:
  • Insecure Kernel v02
  • Root Toolkit
• Enable USB Debugging on your tablet by going to Settings > Applications > Development > USB Debugging.

Reminders

• Create a backup of your tablet’s data in case it will be erased while rooting your device.
• Maintain battery power of at least 60% or more to make sure your device lasts all throughout the procedure.
• System tools such as antivirus software and firewall programs may interfere the rooting process. Disable these programs before you root your device.
• We will not be held liable for any damage on your device arising from your use of this guide. Use our rooting instructions at your own risk.

Instructions

1. Download the insecure kernel image from the link above into your computer.  Rename it into “insecure.img”.  Copy the file into the same folder where adb.exe and fastboot.exe are located. This is usually inside the Tools or Platform-tools folder in the Android SDK installation directory.
2. Download the root toolkit from the link above.  Save it to your computer and extract the ZIP file into a folder on your computer.
3. Connect your HTC Jetstream to the computer using a USB cable.
4. Open a command prompt on your computer.  Change directory to where adb.exe and fastboot.exe are located.
5. At the command prompt, type in the command “adb reboot bootloader” (without the quotes) to restart your device into fastboot mode.
6. From the command prompt, type “fastboot devices” (without the quotes) and press the Enter key.  Your device should be on the list of devices detected.
7. Issue the command “fastboot boot insecure.img” (without the quotes) at the command prompt, then press the Enter key. Your device will then reboot.
8. Disconnect your device from the computer.
9. Reconnect your device to the computer via USB cable.
10. Using the Root Toolkit you have extracted, run the “RUNME.bat” file on your computer.  This final step will provide permanent root to your tablet.

Hooray! You have successfully rooted your HTC Jetstream. With your rooted tablet, you can now flash  custom ROMs and other mods and tweaks for your HTC Jetstream.
