My Samsung SM T560 Tablet seems to be soft bricked. Before this happened, I was in TWRP trying to upgrade it. I wiped off everything besides external SD card (didnt end up installing it, I wanted to check something), and so I rebooted, which it ended up stuck in the 'Powered by Android' screen. Cant access download mode and neither can I enter recovery mode and do a hard reset. Holding Volume down+Power buttons results it in blanking for 5 seconds or so, and then the same booting up screen shows up. Apologies if I missed anything obvious, but what can I do to fix it? Or is it completely gone?
