haha wow ive done this so many times its ******ed. check ur cable for 1 - most of them suck and are only able for charging... first time i ever bricked it i noticed a pattern - i would work flawlessly the FIRST time i plugged it in, bam drivers, etc... then if i unplug (device cannot start) so peel off that back and throw it down for a while you may need to take out that battery a couple times, check out the SWUPDATE method for unbricking, its kind of impervious, othewise ODIN 1.85 and theres many TAR's of full intercept wipes except ODIN seems to hate most of my packages and force closes.
PS my intercept is Virgin Mobile but ive switched to Sprint, Ubuntodroid, blue_rom, Fast Black, everything. And theyve all worked great, even sprint. lmao
