Bought on ebay - locked tablet

[ComfySofa]

As above - i bought my s7+ from an ebay reseller and arrived requiring the previous users key. I contacted the reseller who essentially wasnt interested so got my money refunded from my credit card company (so i bought a new one!) so, ive got this locked tablet to which i can pretty well do anything with this one!.....ive not unlocked anything for a few years (my s9+ still works ok but its heading for it soon...)

Happy to be a mule for anyone that wants to try anything fancy!!
