[WARN]
- This voids your warranty
- You probably can never go back
- You'll never get an OTA again
- You may break something
- You will be bootloader unlocked and can fastboot flash custom ROMs and hacks
If you've got a T-Mobile US Wildfire S, you probably know that HTC has not released a firmware to use with their official bootloader unlock tool. This gets around that by flashing the European GSM unlocked hboot so you can use the tool.
EDGE/3G still works fine, as does Wifi calling. Of course, your mileage may vary.
- Download this file. It's the hboot and bin file mentioned above.
- DON'T RENAME IT
- Copy it to the root of your SD card
- Pull the battery on your Wildfire S, then replace it.
- Boot into bootloader mode by holding volume down + power
- It will find the file, and ask if you want to flash it. If you say yes, there is no turning back.
- Use the volume key to select "yes" and flash the new hboot.
Next, head to HTC dev and follow the instructions to unlock your bootloader. You won't have to worry about trying any of the RUU files, you've already updated your hboot.
Good luck
