    I have just followed online instructions for rooting my galaxy s2 tab, however, now my wifi is constantly in the off position and won't let me turn it on. Can anyone help with a way to fix it or tell me how to undo the root if thats possible

    OK the only way to unrooted is to flash your s2 with a new operating system. It will be exactly as it was on the day you got it.This will wipe all of your data. Do you use a backup Program? Samsung Smart Switch is recommended.
    We need to find exactly what firmware to send to your device, so go to settings, slide the left hand side menu to about device, then hit software info on the right. I need to know your build Number.
    Something else to try is a factory reset after you have backed up. It may cure the wifi problem but if not we can flash it

    I can't help with your wifi problem but can tell you that you will need to flash with stock firmware using Odin

    Just made me register. Thanks for your reply but I'm not sure what you mean. I'm not very tech savvy but had read about all the things you could do if you rooted an android device and thought i'd give it a go. What a mistake!!! Any help in real simple terms would be appreciated.

    No I don't have a backup as this is a new device so nothing to lose. Already tried factory reset but no luck.

    Build number is MMB29M.T713XXU1APD7

    Just tried to reply for waiting for moderator (i think because it contains a link).

    I followed the instructions on tech beasts (search root T713)

    Somehow I seem to have deleted SuperSU so unsure if rooted or not.

    I am a walking advert for not messing with things you don't understand :-

    I agree with Pugs. Reflash the stock ROM and start all over.

    Yes just flash the firmware to your device that matches your build Number. Do you have that Firmware?
