I found a smartphone (typical $10 Walmart LG smartphone). When I turned it on, there is a pattern lock (connect the dots in the right order) to be able to use the phone as a wifi device. I tried various permutations to turn on the phone with no success. A cell phone shop said they could reset the phone for $10, and then told me I could do it myself by simultaneously pressing the power button and volume up (or down) button with the phone off. I tried various different ways of doing that with no success. I was able to get the phone to say "safe mode" in the corner, but I still couldn't get past the pattern lock. Could someone give me some other ideas how to get past the pattern lock so that I can use the phone as a wifi device? It boots up as a Tracfone. The phone is a type that has no sim card, but has a 4GB removable external memory.
