Sorry for my bad english.
While my dad using the tablet, he called me because several errors of processes stopping appeared on the screen. After a few seconds the phone reboot and appeared the screen of encryption unsuccessful. the only thing that i could do was press the "reset" (or similar) button on the screen, but after that he stuck on bootloop, i tried to do the /wipe from recovery but the situation doesn't changed. I tried to flash the WW firmware from SD but i riceve this error:
"-- Install /sdcard ...
check.partition.size=[__PROP_UNDEFINED__]
installation aborted."
What i can do to solve this situation?

PS. I tried to start fastboot mode in recovery but the adb don't see the tablet.

PPS. The tablet is Acer Iconia A1-810

    Try this:

    1. go to acer web page --->support--->drivers and manuels
    2. choose your model acer a1-810
    3. As my divece was bought in usa, my FW upgrade is AV052.RV26RC06.PA.CUS1 (in O.S ), download it !
    4.when it’s done, you should unzip and should get update.zip separately.
    5. Put update.zip on SD card
    6.Put SD card in your device.
    BElieve in YOUrself.

    Thanks sir, but i've already tried to download the WW firmware (my device was bought in Italy, i think this is the correct FW.)  I've put the .zip on my SD, but the tablet gave me the error check.partition.size=[__PROP_UNDEFINED__]
    i will try again.

    That might be one of the errors that happen if your SD card isn't formatted FAT32...
