Bricked Nvidia shield TV 2015-Please help - Shield Android TV Q&A, Help & Troubleshooting

Dear all,
I have an Nvidia Shield Tv 2015 16GB which i had rooted. But recently while trying to return to stock looks like i might have flashed wrong rom and it is completely bricked. It powers on but no display and can't detect in terminal when i type adb devices even though i have all the drivers installed. The Shield shows up as APX in device manager.
Is there anyway to recover this with any toolkits or any other methods please.
TIA
Harish

[Q] Nexus 7 pauses at X screen on start up

Hi i have a 16gb wi-fi model and recently updated the build to Android 4.2.
On purchasing this originally i rooted and unlocked it so i could use stickmount for USB storage etc. but after updating it this app was only working occasionally so i downloaded root checker pro and it said my device wasn`t properly rooted so i attempted to re-root but since then i have had this problem.
I installed wugfresh version 1.6.0 and flash stocked/unrooted in softbrick/bootloop to see if this helped which it done but on start up i had the same problem with pausing at the X screen after the google and unlocked padlock screen.
The only thing i can do is get the tablet into recovery mode but have tried factory resetting this way but no joy there either.
My PC also wont recognise the device now and theres a problem with not recognising adb mode?
Lastly once i unplugged the device from the usb otg lead it turned off and wont come back on so i think the battery might now be faulty/broken.
If anyone can offer some advice for a fix this would be greatly appreciated but i`m not your average tech head so a simplified answer would also be appreciated.
Thanks

Razer Forge TV Bootloop

Since there still isn't a Razer Forge TV forum I'm posing this here... I went rogue and edited the build.prop file on my Forge TV after rooting. After powering it off it has been stuck in a bootloop for the past week. Thanks for @patt2k and some other folks on the Razer forums I am able to get into recovery. However, once in recovery I am limited in what I can do. I don't yet have the system images from Razer, but even if I did I'm not sure I could apply them via adb because my PC doesn't recognize the device at all. It's not the situation where the device shows as an unknown device because the drivers are missing, it simply isn't recognized at all. I have it plugged up via male to male USB cord, but the PC just doesn't seem to take any notice of it. If I could get into adb I think I could get it working again. Does anyone have any clues on what to do in a situation like this?

Unbrick Vontar V6 TV Box – Help needed

Hello! I was wondering if someone could give me a hand. I have researched and tried several things to unbrick my TV box but no luck so far. I was using PhoenixSuit to flash a firmware to my Vontar V6 (H616) box and during the process Windows crashed. After the PC reboot, I noticed Windows 10 recognize the TV box (Device Manager) as Universal Serial Bus controllers -> USB Device (VID_1f3a_PID_efe8) but PhoenixSuit is unable to recognize it again as a device. I tried also flashing the firmware via PhoenixCard as well as accessing the box via adb and fastboot but no luck at all. Based on what I have researched, I believe the bootloader of the box is damaged. So any help or guidance to fix it would be mega appreciated. Thanks in advance, Marcello.
