Hi,

I have exactly the same problem.

Hi @Aquaange and @VFL1900, sorry to hear about this.

It does sound like both of you are experiencing a boot-loop since the Android system never boots up.

I would recommend that you try removing both the SD and/or SIM cards from your tablets (depending on which versions you both have) and try starting up the tablet again.

If there is no change, try performing a software repair using Xperia Companion. Do note that this will delete all data stored on the internal storage of your tablets and since they can't be unlocked, a backup won't be possible to create.

Let me know how it went!
