This will probably be a painful process and I am sure I will lose some data along the way. However as an IT Pro who supports these devices I fell like I need to take the jump and see how the process works.
How will I do this?
Download and install MyBackup from the Android Market. This will allow you to backup all your apps and app data to your SD card or on-line.
Step 1. Backup all data with MyBackup
Step 2. Perform a Hard Reset
Step 3. Run the setup wizard
Step 4. Testing HTC mail client with Lotus Traveler 8.5.2
*** It does NOT work *** Still force closes when trying to open an email
Step 5. Wiping phone again
Step 6. Upgrade to Froyo
Step 7. Run Setup Wizard
Step 8. Testing HTC mail client with Lotus Traveler 8.5.2
*** It still does NOT work *** Still force closes when trying to open an email - arghh
Step 9. Setup Google account and download MyBackup from the market
Step 10. Restore Apps from MyBackup, It's kind of nice that you select all the apps to restore and then it makes you "install" them just to double check that you want them.
Step 11. Restore PhoneData from MyBackup -- Just realized I probably lost all app data
Step 12. Activate phone again by dialing *228 option 1
Step 13. Play with mobile hotpsot and 720p video recording
Next up, Setting up touchdown and the traveler client to see what works and what doesn't.
