A RUU file is an executable file that contains the firmware and software for your HTC device. It can be used to restore your device to its original state, or to upgrade it to a newer version of Android. In this article, we will show you how to use the RUU file named "RUU Buzz Froyo HTC WWE 2.22.405.1 Radio 13.55.55.24H 3.35.20.10 release 160191 signed.exe" to update your HTC Wildfire to Android 2.2 Froyo.
Disclaimer
Before you proceed, please note that flashing a RUU file on your device will erase all your data and settings, so make sure you backup everything important before you start. Also, flashing a RUU file may void your warranty and may brick your device if done incorrectly, so proceed at your own risk. We are not responsible for any damage or loss that may occur as a result of following this guide.
Requirements
A HTC Wildfire with an unlocked bootloader and S-OFF. You can check your bootloader status by turning off your device and holding the volume down and power buttons together until you see a white screen with some text on it.
A Windows PC with HTC Sync installed. You can download HTC Sync from [here].
The RUU file named "RUU Buzz Froyo HTC WWE 2.22.405.1 Radio 13.55.55.24H 3.35.20.10 release 160191 signed.exe". You can download it from [here].
A USB cable to connect your device to your PC.
A fully charged battery on your device.
Steps
Connect your device to your PC using the USB cable and make sure HTC Sync recognizes it.
Run the RUU file on your PC and follow the on-screen instructions.
The RUU will check your device compatibility and then start the flashing process.
Do not disconnect your device or interrupt the process until it is finished.
When the process is done, your device will reboot automatically.
Congratulations, you have successfully updated your HTC Wildfire to Android 2.2 Froyo!
Troubleshooting
If you encounter any problems during or after the flashing process, here are some possible solutions:
If the RUU fails to recognize your device, try reinstalling HTC Sync or using a different USB port or cable.
If the RUU gives you an error message saying that your device is not supported, try changing your CID (customer ID) using a tool like SuperCID. You can find a list of CIDs for different regions [here].
If your device gets stuck in a boot loop or does not boot at all after the flashing process, try doing a factory reset by holding the volume down and power buttons together until you see a white screen with some text on it, then selecting "clear storage" and confirming with the power button.
