unbricking Samsung Galaxy Tab S6 Lite that can not get into Download mode

While installing LineageOS on my Samsung Galaxy Tab S6 Lite, I have ended up with a blue screen that says "An error has occurred while updating the device software." There is also a text in red in the top corner that says: "VOLTAGE Level " While looking online, it appears to me that I am supposed to use odin (or jodin3 for me, a linux user) and then flash the device firmware. However all these instructions appear to be in the Download mode, which I can not seem to be able to get to. The bootloader is unlocked but the tablet is not rooted. I can not figure out how to get into Download mode on this device. I have fastboot and heimdall installed, as well as adb however the problem is that none of these are able to get the device into download mode. In my /var/log/messages/ I get: Feb 12 09:42:04 localhost kernel: usb 3-2.3: new high-speed USB device number 97 using xhci_hcd Feb 12 09:42:09 localhost kernel: usb 3-2.3: device descriptor read/64, error -110 Feb 12 09:42:25 localhost kernel: usb 3-2.3: device descriptor read/64, error -110 Feb 12 09:42:25 localhost kernel: usb 3-2.3: new high-speed USB device number 98 using xhci_hcd Feb 12 09:42:25 localhost kernel: usb 3-2.3: device descriptor read/64, error -71 Feb 12 09:42:25 localhost kernel: usb 3-2.3: device descriptor read/64, error -71 Feb 12 09:42:25 localhost kernel: usb 3-2-port3: attempt power cycle Feb 12 09:42:26 localhost kernel: usb 3-2.3: new high-speed USB device number 99 using xhci_hcd Feb 12 09:42:26 localhost kernel: usb 3-2.3: Device not responding to setup address.

THanks again in advance, for any and all help!
