2. Dell P4 2GB RAM WinXP Pro SP3, this is the PC w/ clean BB DM/OS installation and the first time I tried it w/ ATT OS, it worked (too bad I didn't try pulling battery to test at that time). But then I started to risk with other non-ATT EastAsia as well as ATT EastAsia OS and noticed the battery pull problem. After that, the failure to reinstall OS and/or to pull battery keeps failing one way or another.
Your 1st and second pc are running same OS. Can you find a pc with different OS? I am going to flash my 9700 soon. I can post the result here. My pc is running windows 7 ultimate 64bit.
