    Revert to Android 6.01 from 7.0 Samsung Tab 2

    Hello,
    I downloaded the firmware etc as per instructions to revert back to Android 6.01 from 7.0 as the battery drain was killing my tablet.

    The firmware installed, but it kept rebooting itself. I tried again, and it failed, now the tablet is goosed. It says for me to Smartswitch it to recover it.
    I cannot use smartswithch as I cannot boot it to get the app on it.??

    Any Ideas?

    Glenn

    Hi there,

    What I don't understand: why do first and ask later?

    You can't downgrade from Android 7 to Android 6

    Try to get in Recovery-mode (Vol-UP - Home - Power), then choose FACTORY RESET device

    Hi there,
    I read that you can do it and followed the instructions to the letter.
    Version 7 kills my nice expensive Tab 2... battery drains even when the cover is closed.
    When I use it, the battery drains like mad.

    It was perfect until it upgraded from 6.01 to 7.

    It is useless to me, as I cannot take it anywhere... battery just keeps draining...

    ready for the bin....
    Any advice is greatly welcome

    Hello,
    I managed to get it working- back to 6.01.
    [ Login above or register to see download links. ]
    I had put the file on in Odin, under BL instead of AP. I then did the recover mode and did a factory reset.
    Now it works. It is tricky, even with the Odin AP - firmware and obviously the imaging... it kept rebooting, so the factory reset after, reset it to 6.01 as the image was based on this as well as the firmware.

    I have disabled upgrades.

    Thank you.
