Hello! I have a problem with the cavion Base 7.1 quad. The child forgot the lock code and it is impossible to do hart reset, etc. pressing "volume and power do not give anything, because of the computer also poverty because he can see two disks but empty and you can not enter there etc. I tried to do a hart reset through the programs but they do not see it because the computer probably does not see it too much, after connecting the tablet to the computer, the tablet screen displays "Unfortunately, the com.android.systemui process has been stopped." What else can you do, can you upload some software via the SD card?
