Device not booting

[Jisifus]

Hey guys, looking to troubleshoot a (hopefully) simple boot issue with my wifi-version note 10.1 2014. Nothing happens after the Bootlogo after flashing the latest LOS 14.1, with or without gapps. The backlight is active but there's nothing happening, even after about an hour. I'm running out of ideas here and just hoping there's something wrong with the modem/firmware whatever even though flashing works perfectly. Appreciate the help...
