I have Galaxy Tab 3 10.1 GT-P5210. I forgot the lock screen password, so I tried to hard reset the device using the recovery menu. (Power button + Volume up). When I tried to hard reset, I got a lot of errors. I don't remember all of them, but I know that one of them was E:format_volume: make_extf4fs failed on /dev/block/mmcblk0p9, and other error was E: failed to mount /cache (Invalid argument). The other errors were similar. I tried again, and the same result. I tried the option of 'wipe cache partition', and I got similar errors. (Or the same.. I'm not sure) After that, I decided to try to get into the recovery menu again. So I pressed the reboot option, and I was pressing the volume up with the power button while it was rebooting. And then, nothing happened. The device didn't power on again. I tried to charge it, with no success. I also tried to do a soft reset (Power + Volume down), and nothing happened.

There is something to do?
