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

Delete Userdata

I'm trying to delete userdata using fastboot, but this command "fastboot erase userdata" gives me okay reply, but when I reset phone, the userdata is still there. Any ideas?

Fastboot operates on phone's bootloader, not on Android OS where user data are stored in.
Use ADB to remove user data.

fastboot commands disabled on locked bootloader. post full output pls

Wrong: on devices that support fastboot you after having turned on OEM unlock you e.g. run
Code:
fastboot flashing unlock
to unlock its bootloader.

right. fastboot boot format erase flash are forbidden in locked state, to be nitpicky...
unlocking bootloader will perform factory reset, therefore it is protect by OEM toggle in developer options, too.

the phone's Bootloader is unlocked, and I can't do anything else with the phone when it can only fastboot. I can't even normal start phone to go into ADB.......

Re-flash Stock ROM, and if successful immediately enable ADB.
