Purchased a Kocaso 1050s tablet off ebay. I think I hard reset the device but I am still be prompted for a user name. I tried USB connection to PC but device is not regconized. Ideas appreciated - believe OS is 2.3
Right, I used sequence for another model power off, power+menu, release power upon startup and release menu on adroid icon. It seems to reboot differently and the date was reset but, still being prompted for username.
You should be able to hold the power button down and the volume up (left side closest to power button) and it should bring you to a system screen that gives you the option to do a factory reset. You would use your volume buttons to scroll up and down and the power button to select. just scroll down to data wipe/factory reset and it should work.
