Not understanding how to flash jetson tk1 :o

Also haven’t been able to understand this
Lastly I have a black screen upon boot.

Try this one:

I am aware of that site too. I guess my biggest issue is that I cannot see anything.

I’ll try to explain it:

First of all, you need to have a host computer running Linux. This is the computer you will use to flash the Jetson. (A virtual machine will work, if you’re running Windows)
Connect the micro-USB cable that came with your board from the micro-USB port on the board to a standard USB port on your host machine.
Start the Jetson in ‘force recovery mode’: Press the POWER button while holding down the FORCE RECOVERY button. Open a terminal on the host machine and type ‘lsusb’. You should see a device in the list called ‘NVidia Corp.’ The Jetson is now connected to your host machine.

Now, download the L4T package ‘Tegra124_Linux_R21.2.0_armhf.tbz2’ if you don’t have it already.
Download the sample root filesystem to the same directory (named Tegra_Linux_Sample-Root-Filesystem_R21.2.0_armhf.tbz2.)
Run these commands in order (making sure your current directory contains the above files):

sudo tar xpf Tegra124_Linux_R21.2.0_armhf.tbz2
cd Linux_for_Tegra/rootfs/
sudo tar xpf ../../Tegra_Linux_Sample-Root-Filesystem_R21.2.0_armhf.tbz2
cd ../
sudo ./

And finally:

sudo ./ -S 14580MiB jetson-tk1 mmcblk0p1

I couldn’t find the package for Tegra124_Linux_R21.2.0_armhf.tbz2
But I found an older version and followed these steps. Anyone know where to locate ‘Tegra124_Linux_R21.2.0_armhf.tbz2’ ? Maybe the file I have to get isn’t called that by name ?

Under the Linux For Tegra R21.2 page:

See the link just below “Driver Packages”, named “Jetson TK1”:
