    Galaxy Tab 2 10.1. After an unknown update awhile back (my wife's tablet, but she thinks it was a system update), the tab appeared dead. Cracking the case let me verify the battery had a full charge. Connecting it to a PC showed me it seems to be trying to boot (OMAP 4430 driver request) but fails and reboots. This loop has a period of about 2 seconds or so, making me suspect the bootloader or boot chain is corrupt.

    Screen never comes on, so no logo or icons are ever seen.
    I have yet to make it shut down except for running the battery dead.
    vUP+Pwr, once finally off, starts the loop again once I let go.
    vDwn+Pwr does the same.

    Thanks,

    About to give it a try but I'm thinking it won't work since I can't get it to boot into ODIN mode either.

    Hold on power SHOULD shut it down, but I've yet to have any luck doing so.

    Long press either doesn't turn it off or holding it down too long turns it back on. It's hard to tell when the only indicator is Windows' device manager popups.

    Unplugging the battery doesn't help since it turns back on if it was on when it last had power.

    It's amazing how many days this thing can bootloop on no more charge than it can get from being plugged into the pc for 30 minutes...
