Here were about 10 or might a bit more bricks since this hack USB is used. Compared to download count of file it is low percent, less than 1%. But every brick is important for us, because Tv is not cheap gadget, and we don't want risk. It's up to you use this or not. You can find hack usb here on forum too. When it will be fixed or when the new version is released? That's good question. I do not know. Noone knows. Just the developer, who is gone away from our horisonts few months ago. He promised to fix it someday. I hope he does.
Another way is to root your tv without hack usb, do everything manually. Usb makes process automated and adds some features, but it could harm your device.

dont expect any updates of hotel hack. AFAIK

You may choose the method without usb-image (link just beneath)
the end-result of the preparing-step in this method is nearly the same usb-drive as in the universal hackdisk method but only with the things you need...

we discovered simple unbricking procedure if hotel hack failed, but works only of you've set rs232 to debug and watchdog off.
