Unhappy ACER A500 APX mode

hi to all

I do not know if it's the right place for this post

I have a problem with my tablet A500 (never changed).
after it is blocked on the Acer logo, I wanted to update it with the different method found on the site.

but after using the software EUU file, it tells me that the update is OK but the tablet is rebooted.
So I put out after a certain time and when I turn back, it remains in APX mode.

you have a solution before I destroy

help me

PS: desolated for my English because I'm French lol
