Thanks Diddy, but I'm unable to get past the first step.
My tablet won't boot - I just get a permanent loading screen, therefore I have no access to any of the device settings, only the options available through recovery mode.
Before I had these issues my device was still locked, USB debugging and OEM unlock were disabled, I am unable to enable them as the tablet won't boot.
I'm assuming there is no way to flash the device if it is still locked, would this be correct?
I'm also assuming that you cannot unlock a device via recovery mode, is this correct?
If both of the above are true, would it be advisable to enable USB debugging and OEM unlock as soon as you get hold of a device to avoid these problems in the future?
