    I rooted my Pendo tablet so I could spoof my Wi-fi MAC address. Now my tablet's MAC address changes at every boot up even though I haven't done anything to change it. So far it appears to be a good thing in that I haven't had to actually do anything to change it and the tablet still works fine.

    Is there some way to confirm that the MAC address is actually changing and that the MAC address as shown in About Tablet - Status is what the MAC address really is? Maybe a web site that can read it? I can't physically connect the tablet to my Wi-fi access point.

    I suspect the root process, whatever it did, might have damaged and corrupted files that are to do with the baseband, which is what decides the MAC address, which should always be fixed. And the fact it can't connect to WiFi now, could possibly indicate a corrupted baseband firmware.

    No firmware files online for Pendo AFAICT, so you might need to contact them about re-flashing it.

    I can connect wirelessly to my Wi-fi modem, just not physically with a cable. The Wi-fi on the tablet works fine. I was just wondering if there was some way to confirm that what the device says the MAC address is is also the same MAC address it is sending to the modem. I factory reset the tablet last night and the MAC address still changes with every boot.

    If you can log-in to the modem's admin page, there may be a "wifi security" section that allows filtering MAC addresses. All MACs visible on the network should be displayed, allowing you to compare what the tablet shows to this list.

    Just about any wireless router will have a setup menu with some kind of variation of a 'connected devices' page. There will be a listing of any devices connected to the LAN, by name and IP address, and often MAC address. What kind of router do you have?

    You could also install a networking analysis app like Fing onto your tablet.

    Just do a basic scan of your local network and in the resulting list tap on the entry for your tablet. The MAC address will be one of the items in the window that pops up.

    It sounds like you damaged or corrupted your device's EFS partition, which is not good. The EFS partition is which is where the wifi mac address, bluetooth address, IMEI number, radio configuration data, and much more important data is stored. If you have a custom recovery installed you can just make a backup of your current EFS and every time you have to reboot your device, you can just restore the backup. It sounds like a small pet-peeve if your in a rush to do something, but it helps.

    If that still doesn't save your Mac Address, then you may need to backup all your data, then flash back to stock. Some partitions are handled differently on other devices, but its not recommended to mess with anything sensitive in your device if you don't know what your doing.

    For information, using Odin would only be any good if the device in question was a Samsung. The OP here has a Pendo tablet. :)
