    Hi all, would really appreciate some help please.

    I've got a rooted tablet that was working fantastically for a while (thank you to vampireifo for rooting help).
    Last night for no reason what so ever the sound stopped, both from the speaker and headphone, to fix this I tried a CWM back up. That didn't work so I flashed vampireifo's cf9 rom, which worked but still no sound and also no wifi, so reverted to the very first cwm back up I did, Wifi worked still no sound.

    Next thing I did was a wipe data/factory reset to try to reset the sound, still no sound, but wifi and screen worked, so decided stuff it, I can cope without sound.

    In the end decided to revert to my latest back up with cwm mod, now I have no working touchscreen.

    Any advice would be much appreciated, I do have a system dump available, but when i try to use cwm to install dump from zip it wont do it.

    Please note, returning or exchanging is not an option as it is a second hand tablet and well out of warranty.

    once again any help would be much appreciated.

    ok, change of problem, sort of....

    Screen now sorted, can use tablet again, just don't have any sound, apart from a glitch that I created, had netflix running to test the sound, hit the power button to put it into standby and the sound suddenly came on for no reason, very mystified by this, so any help please.

    Sounds like hardware problem, your speaker wires are rubbing or shorting out.

    would the wires cause the headphone jack to stop working as well?
