Apme A86 tablet, it would power on but then gets stuck and no movement at all

make sure you have charged the tablet, or have the power cable on during reset.
Just try resetting again. If it does not work contact the polaroid service centre.

The robot dude meant it was loading up the system settings to the next screen so you can wipe off corrupted data that prevents the tablet from completing startup.usually an incomplete update.So
as follows ... Hold power button to switch off tablet....then hold power button and volume up together for at least ten seconds.let the robot appear and do nothing until the menu option comes up to ask you to factory restore.you will lose all your apps and data.if the robot comes on and gets stuck make sure the tablet is fully charged and repeat the two button hold as this may take several attempts.sometimes Chinese technology is unpredictable.

Don't forget to plug in the power. And again, press home button and on / off switch, till it switches off. Then press the on / off button, till the Apple logo comes back, then release the button. It can take up to a minute, before the screen comes on.

use this program chines tablet software

So I guess nothing else to do but to get it to boot from a SD card with Android 4.1 on the SD Card, It appears your's is corrupted, there is a number of sites where you can download along with directions to make an Android boot card. Hope this gets you up and running.

hi try doing it this way.all data will be lost...

1. Shut off tablet
2. press the volume minus button and the power button @ start up
3. tmax logo shows up and then a android menu
4. factory reset
5. Once complete, reboot
6. wait 4-5minute... tablet works again

press the power and volume down simultaneously for 5 seconds or more until the tablet resets or goes to service mode . If service mode activated select reset tablet

You'll need to do a factory reset:
1. With the device off, press and hold Volume Up and Power.
2. Release the Power button when you see the logo, but continue to hold Volume Up until the recovery screen appears.
3. Use the Volume buttons to navigate the menu and select wipe data / factory reset. Press Home to choose the selection.
4. Press Volume Up continue.
This will reset you device to factory settings, however anything on your SD card will still remain.
At this point you will need to start fresh as if you just bought the device -- register with your email address, etc.
