Always use loader.exe. Never use the DM.
Always have ONE installed software package at a time - never more.
Always make a backup.
Always make sure your device is UNLOCKED (enter the password) before you do an upgrade.
Since you seem to be stuck at a common sticking point, jsut unplug, restart the phone and the comptuer and try again.
As i said above, enter your password before doing the upgrade.
IF the battery pull / comp restart does not work, you will need to connect the device using the /nojvm command lime flag for loader.exe
best of luck
