With so many fails on this area on tablets what we use on a PC does not apply. Folk are finding themselves with bricked tablets and having to buy recovery kits from the tablet maker.
I rooted my acer iconia tab 8 a1-840. It worked great! I saw that I had an update, so to install the update I needed to unroot the tablet. While unrooting the tablet an error ocurred. I disconnected the tablet from the computer and this message appeared " EFI hard drive has been blocked by the current security policy". I've rooted and unrooted many devices, I've never recieved this message before. I have tried everything possible to get the tablet to boot up with no luck. Have I finally bricked it for good? Or is there a way to get around this obstacle? Any response would be appreciated.
