Default [Q] Nvidia Shield black screen on boot

I rooted my Nvidia shield a day or 2 ago and everything was working fine, until i i went to the play store to look for some apps. it wouldn't connect. i tried everything anyone suggested and nothing worked. i tried completely resetting the whole thing. that didn't work. then i found a guide at http://forum.xda-developers.com/show....php?t=2110225 and at the bottom he explains that if you delete Hosts file under system/etc/ and reboot and Wipe Cache/Dalvik Cache. well i ended up deleting the whole system/etc/ folder. i so dumbly deleted the whole thing and now my nvidia shield will not boot. it gets stuck on a black screen during the boot process after the nvidia shield thing comes up. i tried reflashing the root_shield.img, i tried the recovery options and thats not working. please help me
Thank you.
