Ok, I will try to see how it goes. Regarding the recovery software, I wanted also to have it before I flashed the tablet but unfortunately it's offered only for developers and you need to have the receipt to attest the date when you bought the product, which unfortunately I didn't found in my papers... and I think is not other option to get the software. Probably I don't have other option than to send the device to service. Thank you for your answers and support! @TPFLegionaire
