You'll need to download a brand new rom for it. Your phone will run Windows Mobile 6.5 perfectly, so it's definitely time to upgrade. You'll need a computer running at least Windows XP, your USB data cable, as well as Windows Mobile Device Center installed to upgrade your rom. Once the software is installed, connect your phone to your USB, and start the .exe file for the rom. Make sure you have a full battery before upgrading your rom, and DO NOT TURN OFF YOUR PHONE even if it looks like it has locked or frozen - it hasn't. The file can be found here. http://www.htc.com/www/supportdownload.aspx?p_id=179&cat=2&dl_id=533 Input your serial number, and select the rom upgrade in the drop down box, make sure your phone is connected and charged, and that WMDC is running, and click the file to start the upgrade. Again, DO NOT TURN OFF YOUR PHONE even if it looks like it has locked or frozen. Leave your phone upgrading for a while, go have a cup of tea. When you get back, you'll have an upgraded operating system, and a phone with English as the language. Any problems or questions, please feel free to reply.

From your explanation, it sounds like you've downloaded an app or program that has a driver conflict with the phone's operating system. You may need to flash your phone's ROM (operating system) with a new updated version to get it to work properly again. Since you didn't include who your cellular carrier is, I'm going to assume that it is AT&T. If the phone is not an AT&T Branded phone, disregard these instructions.

This phone is also called the HTC Tilt 2 (AT&T) and there is a new ROM download for the phone which should solve your problem. You'll need to follow the directions EXACTLY to flash your phone's ROM - and I do mean exactly!

This software update is intended for the HTC Tilt 2 for AT&T only and users should not load or attempt to load this version on any other device as it may cause serious issues/damage.

Please note that during the update process, the device will be Hard Reset and anything that is NOT part of the Operating System (contacts, calendar, music, etc) will be permanently deleted; always make a point of backing up your device's data on a regular basis!

Before you proceed, please confirm that this software upgrade is a newer version than what is currently loaded on your device. If it is the same version and your device is operating normally, there is no need to reload the software.

To determine the software version running on your device, go to Start > Settings > System Folder > Device Information > Software Information.

Validate that the ROM version is 2.10.502.4 if it is not, you will need to update the software on you device.

Before you run the ROM Upgrade Utility (RUU), make sure you check and do the following first:

• USB sync cable is connected to your device and PC to establish a connection with Activesync/Windows Mobile Device Center. If you don't have ActiveSync installed on your PC already, the CD found inside your handset box can be used to install the application. If you lost the disk, please go to www.microsoft.com >Downloads & Trials> Windows Mobile Downloads and download the appropriate application (ActiveSync or Windows Mobile Device Center) depending on your PC's OS. You will also need Outlook or Outlook express installed in order to backup your contacts, calendars, e-mail, tasks etc.
• Remove your storage card prior to running the upgrade. Do not put it back into your phone until after the upgrade process is complete.
• The standby and hibernation modes are disabled on the computer.
• All running applications on the computer have been closed.
• Ensure that you device has a battery level of at least 50% (Start > Settings > System Folder > Power > Battery) If the battery "dies" during the upgrade process, there is a chance that the device will not recover and will need to be sent to HTC for repair.
• The update can take several minutes so set aside time when you will not be interrupted.
• Do Not interrupt the upgrade process or press any buttons on the device until the process has been completed (the device will reset itself when the update is done).
• Warning: Installing this update will erase all data stored on the device, restoring your device to the factory default settings. Please be sure to back up any important files to preserve your data.

General Procedure on Installing the ROM Update

1. Back up your personal data from the Mobile Device to your computer using ActiveSync (Windows XP or sooner)/Windows Mobile Device Center (Windows Vista and Windows 7) or a 3rd party backup utility if you want to ensure you don't lose any of your data.
   • If using a 3rd party backup utility, be sure that you are not backing up the Registry as this will cause issues once restored to the device after the update.
   • You will need to reload any 3rd party applications manually. Once you have created your backup file, be sure to copy the backup file to a storage card (ensure that Storage Card Encryption has been disabled on the device if you have enabled it) or to your PC before proceeding with the ROM update.
2. On your computer, click on the Download link (below) and save the file to your desktop.
3. Establish a connection between ActiveSync/Windows Mobile Device Center and your device using the provided USB Data cable.
4. Locate the ROM file (the one you saved in step 2 above) on your PC and double-click on the file to run the ROM Update Utility (RUU) to install the ROM update to your Mobile Device.
5. Follow the RUU Wizard prompts. When presented with the readme screen, please read the Readme since it provides a lot of valuable information on the upgrade process and what you can expect during the upgrade process. Check the box beside the "I understand the caution indicated above and has reviewed the Readme" and then press Next to continue. The remaining steps will typically involve checking the check box and pressing the Next or Upgrade button until the upgrade is completed.
6. Restore your personal data back to your Mobile Device using ActiveSync/Windows Mobile Device Center or the 3rd party backup utility you selected.

Are yous sure it is running CE.NET 4.2? I dont think that the HPC 2000 version can effectively use the USB host. If it is HPC 2000 after all, upgrade the ROM. Try http://hpcmonex.net/nec900/roms2.html to upgrade your ROM.

I don't think that's possible as unlike the newer machines the 54x series has the OS embedded in ROM. Even so, I own a 568 but notice that there are no plans to provide an upgrade to PPC 2003 so we'll both have to get Ipaqs :-(
