Did you apply any OTA Update to your *ROOTED* phone? Read here for fix.

First and foremost, you cannot apply OTA updates to rooted phones. Doing so will cause a boot loop. If for whatever reason you did this anyway, I quoted a fellow XDA member with instructions to fix your phone.
* I did this just to be helful and for those who keep on posting questions and spamming the board because they did not read this q and a faq http://forum.xda-developers.com/showthread.php?t=1220484. I suggest you read all of the post at the provided link after fixing your phone. All future questions you may have will most likely be answered there.

What's the best way to wipe an Android phone?

I have a T-Mobile HTC Hero. One thing I did, was reinstall the operating system, by downloading an updated OS from the T-Mobile website, and installed it using HTC Sync.
According to HTC Sync, this wipes everything on the phone and installs the new OS..
But is this actually the case? Does this really completely wipe the phone before installing it?
What I am looking to do... is completely wipe the phone, and then install the new OS. If I've already done that, good. If I haven't, I need to.
If you go to Settings and do a factory reset, that only resets user settings and removes applications. It doesn't wipe the OS and everything on the phone. As said, I need to do all of that, and the install the new OS.

You can either:
1) To initiate the Android device wipe process, first tap your Android Menu key to bring up a number of on-screen options.
2) Next, choose the Settings option within the on-screen menu, and on the following screen scroll down to and tap Privacy.
3) Within the Privacy Settings menu, tap the Factory Data Reset option, and on the following screen choose whether you want to wipe all data on your device, all data on your external microSD memory card or both, by filling in the appropriate check boxes. Then confirm the action by tapping Reset Phone.
4) You'll be prompted one more time to confirm your Android device wipe on the Factory Data Reset screen, and if you're sure you're ready to erase your device, tap the Erase Everything button to complete the process.
or to delete the data from your phone and to install a ROM:

Reboot phone and then:
1. Press down button and Power button together.
2. Use the volume down button to select recovery then press the power button.
3. Okay use the volume down button and go to advanced three times.
4. Press the power button and use the trackpad to select.
5. Wipe/factory reset and then select yes.
6. Wipe cache
7. Select advance
8. Wipe dalvic cache
9. Select install from sd card then select the ROM you wish to install.
NB: I am not responsible for any data lost on your phone for the above.
