Change setting Unifi to Streamyx will force box to use login id/pw...you can then use wifi and any other Lan ports not just port 4...at least my V5 works this way...
AFAIK lite no more free box

Is the STB connected to the right port on the main router? Standard connection and not through some power plug, etc.

The ideal/standard setup is that the STB be connected via ethernet cable to LAN port 4 on the main/TM supplied router. Some have been able to get it to work wirelessly, but will require extra equipment.

Factory reset if possible or see my previous post.. Easy... There's a search function people.. Either use it or read first before complaining.. 

The pass code for the OLDER firmware is 3008.. Try that.. If it doesn't work, means you have been updated to the newer one.. If so, then my previous post still applies..

That's probably because you are supposed to be using the specifically made for TM and that device Hypptv app. Anyway, you can try either of the following. Starting with the Tablet version first. FYI, the Hypptv Everywhere app is a tricky one and even on non-TM supplied STB, it's problematic and not all of your subscribed channels will work.

Phone version.
Tablet version....

USB?

As for YouTube.. You are not alone.. Search his thread for issues relating to YouTube. Frankly, I don't use the device.. Too much hassle.. Better off buying a more capable device..

maybe defective ports or the pendrive itself? Cuz the usb port on mine works.. Works for others as reported here too.. Try wiggling the pendrive in the port a bit or don't push it all the way in.. Probably get better contact that way.

Ya.. Mine barely gets switched on, except to watch local news.. It's either the TV's smart apps or the trusty Neo U1 box. For YouTube, I use the TV app. It's faster, easier to navigate, cast & queue videos from phone or tablet and best of all, don't have to power on the Neo U1 just for that. 

Yes, If you know how to do it safely without crippling the device..
No, If you don't or are not bothered.

Remember, If it's not broken, don't go fixing.

hypptv everywhere 6.4 apk and below does work.
the parse error due to android 4.42 min sdk requirement not met

The TM white box has very low memory available even after a factory restore. You need to how how to removed other apps that is not useful to free up the space for the apps you wanted.

These box are okay. Is working fine for me if you now what that work best with it and how to install.
Utilize something that is free and make the best out of it. 

Too bad and not unsurprising.. Try gaikon's suggestion.
Free isn't always good... It's 2017 boss.. No reason to continue living like "cave men"... No use building a tinder nest, making notches and spinning to get fire, just striking a match or lighter will do..   Call it, me being older or having the budget. I'd rather have a not so expensive - expensive device that powers on, does ALL I require as per current popular media capabilities, and goes to sleep/shuts down like a boss, than a device I have to constantly cajole into playing or performing the basics of tasks.
