I found this on Android Central (thanks to IzelTokatl) and someone there did verify it worked for OTA 2.1 phones. I tried it on my leak version 3 phone and I got the Hboot error again. I'm thinking this does not bode well for phones with the leak as once Verizon releases the upgrade for download from PCD or HTC we still won't be able to use it until the Hboot problem is fixed. The following instructions for doing the downgrade to 1.5 are cut and pasted from the Android Central forum and I edited them for PC's: Download the MR2 Upgrade Eris ROM from verizon partner: Personal Communications Devices 1. Unzip the file 2. Plug your phone into your PC. 3. Navigate to folder ADR6200_MR2_Upgrade 4. Run .exe file in the folder (RUU_Desire_C_Verizon_WWE_1.17.605.1_release_signe d_with_driver.exe) 5. follow on screen instructions.
