ok. first off, device is a shield K1 wifi only version.

device bootloader unlocked, fastboot says "device - unlocked

initially was on TWRP 2.8.2.0 and lollipop 5.0.1

it started as booting from the NVidia logo into a black screen.

I then tried "Shield + Ram"
tried flashin CWM, superSU then bonestock firmware (4.3 JB)

rebooted and it is still in a boot loop. "NVidia powered by android"

flashing with "Shield+Ram" , CWM , ------------- booting into fastboot then recovery mode, it goes into bootloop at "NVidia powered by android"

flashing with "Shield+Ram" , "Stock Recovery" , ------------- booting into fastboot then recovery mode, it goes into bootloop at "NVidia powered by android"

flashing with Windroid universal android toolkit, default TWRP. ------------- booting into fastboot then recovery mode, it just stays stuck at "NVidia powered by android"

flashing with Windroid universal android toolkit, with twrp-2.8.6.0-shieldtablet.img. ----------------- booting into fastboot then recovery mode, it just stays stuck at "NVidia powered by android"

booting normally,it would just go into a boot loop of "NVidia powered by android"

pretty much at my wits end.

any help is much appreciated.

that said, with WinDroid, I tried flashing SuperSU, it says "No Device Found"

WinDroid detects Nvidia Shield as "Fastboot" with a blue dot on the bottom left of the window of the windows app.
