Hello and I need advice on how to get into a blocked tablet (Allwinner Q88.7 "). I borrowed it from my nephew (100km from my place of residence), he did not use it for a long time and forgot the combination of points for unblocking. The phone tried various combinations until the tablet reported that we had exceeded a number of attempts. The display showed a protocol to log in to a Google account. All attempts at hard reset are unsuccessful.I turned off the charged tablet and held the start button with volume + i -, even for a few minutes and nothing. The only change occurred when I tried this when turned on and the oncoming tablet, the text "emergency mode" appeared at the bottom left of the bar, but there was nothing you could do about it anyway. ola different icons, when I select one, the display switches back to the login protocol. Does anyone know what to do with it? Thank you
