So you decide to revert back to the official rom or you need to return the phone for warranty or you are selling it. Here are some simple instructions:
You will need:
- Windows 7 Home Premium Edition 64-bit
- Actually any version of Windows XP or later or Linux could work, but these instructions were written using a machine with Windows 7
-
HTC SYNC UPDATE
- HTC HERO (SPRINT) 2.1 SOFTWARE UPDATE
Steps
- Backup everything on your phone!
- I like SMS Backup (Christoph Studer) for backing up my SMS and MMS messages to my Google Mail
- If you have a Google account you can login to it on your phone to backup all your contacts
- Remember to backup your SDCard contents too
- Install HTC SYNC (or the USB drivers) before running the RUU update or plugging in your phone
- Plug in your phone to your computer via USB
- Make sure your phone is in USB Charging mode and not USB Disk mode
- Run the HTC HERO (SPRINT) 2.1 SOFTWARE UPDATE
- Go through the prompts
- Once complete you should reboot your phone and the original factory ROM will be installed just like you never used it before
- Login to your Google account on your phone to restore contacts, etc.
- You can also manually check for OTA (over the air) updates on your phone to update it to the latest official version
