It's a little bit weird because Sony mobile lets you unlock the bootloader of your smatphone (http://unlockbootloader.sonymobile.com/) and also gives you an official tool, whereas with Sony Talets you can't do anything. I'll never understand great companies' choices. Anyway I hope it will be soon possible. That's the only thing we can do, to have hope, other than risk to brick our devices.
Hello Lorenzo, Welcome to the User Discussion Forums. If you ever need an immediate answer from Tech support we have chat support available here: https://www.docs.sony.com/startchat.asp For a prompt and live response.
Our Forums here are a way for the community to connect, share and help each other. We as moderators do our best to step in when the community has not responded. As stated by my colleague Dan in January. Rooting your tablet (bootloader) is still not recommended nor supported . If your tablet is no longer booting to the operating system please contact service for repair options.
Thanks, my tablet works perfectly, I just only needed a clarification, an answer more recent than the previous, on internet there are so many rumors, I'm sorry, I also knew my second post wasn't polite. Thank you again for your patience and assistance.
