I have a Samsung SM-T311 and it stopped working days ago. It wouldn't boot or charge. Recently, a message appeared in the screen, "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again".
I can start in Download Mode screen sometimes, with the USB cable in my PC. But as soon as I press "vol up" to enter the Download Mode, it restarts into the "Firmware upgrade encountered..." screen.
So, I have now an incredibly unstable tablet, that won´t boot or charge unless connected in my PC. And even connected, the only thing it shows is that message in the screen. Download Mode is not reachable, so I cant restore it in Kies or Odin, since it cannot be detected.
I know, it´s a mess. But before I send it to any repair services, there´s anything I can do to try and restore my device?
Thanks in advance.
