Uh-oh I tried this on my Blu Studio C D830U. First using Win 7. Didn't work, so tried it on XP. Pretty much did the same thing (stuck on 'please wait a moment'). However, after unplugging the device, it said that the recovery was successfully installed. I used flashify to reboot to recovery. Phone powered off and now won't power back on at all. Can't remove the battery, because it's built in. Any ideas?
