Yes i have the cable.
@sam_nazarko still waiting for the commands and how to proceed 
Thanks for your patience.
Good to hear you have a USB-A to USB-A cable.
Please confirm itās USB-A to USB-A and not USB-A to USB-C and not an adapter (some will work but some wonāt).
Take the file called āupgrade.imgā from the SD/USB and copy it to your desktop somewhere.
Then on a Windows PC (cannot be a VM), install the tool via the link sent to you via PM. There is a Linux and macOS tool but they are not very stable.
Open the tool.
Apply the USB cable to the device and hold the toothpick in as you apply power. It should then appear as detected on the PC.
And select the image āupgrade.imgā
Donāt change any of the checkboxes and click burn.
This should restore the device to a good working state. It will take several minutes. When confirmed as successful, unplug the cable and connect it back up to your TV.
