fastboot boot question

Note: This is not related directory to the Shield, it's about HP Slate 21 (they both use Tergra 4)
I would like to try the root_tn7 image on the Slate, I'm booting into bootloader mode, I see my device in the fastboot devices command.
But when I try to boot the root_tn7 (using: fastboot.exe boot root_tn7.img) it gives me:
downloading 'boot.img'...
OKAY [ 0.849s]
booting...
OKAY [ 0.071s]
finished. total time: 0.926s
Click to expand...
Click to collapse
Which means it's totally ignores the root_tn7.img
I heard that there is a kernel parameter (with -c) which needs to be passed.
Any suggestion to which parameters?

:\ It should work... "fastboot boot root_tn7.img". Have you tried removing the boot.img from the folder?

There is no boot.img in the directory I'm in....

It seems it just uses "boot.img" as what it's doing...

The TF 701 is also tegra 4 based. Yesterday I was able to use a TF 701 Clockwork disk in fastboot boot mode to root the slate 8.
Even if the root script doesn't work, if that image will boot your system you ought to be able to push su to /system/bin and chmod it, then install SuperSU by hand if need be.
Try the one from this thread:
http://forum.xda-developers.com/showthread.php?t=2524401
That specifically targets Tegra 4 systems running Android 4.2. There's a second TF701 clockwork tool, but it targets a specific bootloader and would not boot my Slate 8.
Good luck!

Who's your carrier? If its boost it should work. Try again after a few minutes. It happened to me once. If its Verizon then you can't unlock it

i think i 'm stuck like you
availables solutions are :
1- get the FRP key and unlock it via fastboot then unlock bootloader.
2- flash the correct firmware with tool that use Dload mode (dc-phoanix.....)

So I have roll back to emui 5 (with dc phoenix and hcu thanks to them) and I will wait that I have more time to understand how to go to oreo thanks for all your answer
