Root-able Android TV?

I am looking to do some development for Android TV and need a physical TV to test on.
I have access to a Philips Android TV (2015 model) and there is no way to sideload an APK (this has been confirmed fully by Philips themselves)
So I need to get a new physical device for testing purposes.
Does anyone know of an Android TV make & model that allows for sideloading APKs?

What model do you have? 49PUS7150 can be easily rooted. Follow this this guide...
It's a 5500 model, so no ADB at all

Your TV is based on chassis QM15.2E LA. Other users have claimed that after the released update of official firmware from March 18th in firmware version QM152E_000.005.210.000 ADB and unknown sources are enabled...
You can intall APKs on the amazon fire tv. but I'm not sure it this is what you are looking for. As it is a modified version or android the google play services and so on are not visible

Android OS on projectors like the Nebula Mars

]The Nebula Mars, which is made by an offshoot of Anker, comes with a custom OS running on Android 4.4. For the unfamiliar, it offers a decent projector in a small size, combined with a battery for portability.
Since this isn't a phone running a typical phone ROM, I'm hesitant to root it and start tinkering, but the stock OS and software is absolute crap. The system allows updates and installation of APKs, but the company says they have no intention of issuing a firmware/ROM update.
Any advice on where to find others who have this device and are also interested in modifying the OS or updating to a newer version of Android? Any recommendations on approaches to non-destructively modifying the OS? I don't think it has a separate partition for restoring prior ROMs, and I'm just inexperienced enough that I'd end up bricking it.
Same question about the Nebula Mars Lite model
So I webd to Walmart and found that they sell the lite model for $349. The problem is that there is no android at all. I am not sure if the hardware is any different because both models look identical. I wonder if there is a way to either install the original mars OS on it or something better ie costom rom of some kind.
Hey ! I'm also interesting in upgrading the OS of my nebula Mars... Any news for this project? Thanks !

just grabbed the Lite version ($180 at my walmart) and it looks like it is running android (lollipop it looks like, PC shows "lollipop" when connected to the wifi settings page) but it's locked away behind it's launcher...
that's all I was able to figure out.
Nebula Mars 2 is on the market with Android 7.1. Anyone trying to port it to Mars 1 please?

[Help] Understanding the difference between Android over different platforms/devices

Hey guys,
I will try to post my question and problem as clearly as I can :
What is the difference between an Android OS TV (example mini PC with Android to make your TV smart) compared with Android OS for your personal Phone device or tablet?
For example : I have an Odroid Mini PC from Hardkernel, with Android OS fw 4.4.4 with root. I also have in my home several devices such as Android TV (came with the Smart TV). The main problem is what or where is a root file system that allows the TV to be found in the network?
The question is : When i use the Google Cast from youtube, Why i Can't see both devices? Where or What i have to do in order to make this option available.
On my personal device (phone) Asus ZenPhone 2 fw : 6.0.1 and Odroid Mini PC (fw 4.4.4) i found on different websites the possibility of the app "CheapCast" which cannot be found anymore on Google Store
If I run from Windows (Chrome web broser) the option to "Cast to device", I can only see the Smart TV , not the phone or the mini pc. The thing that disturbes me that if I use the YouTube App from any Android Device, i can select all 3 devices . Why?
Thank you for your time.
Please tell me if i didn't make myself clear, i can create a gif to display the issue or re-tell the story

Installing Nougat on any device?

Hi guys, I have a question for you. I have a tablet, which is not supported above android 4.2, but it is not that old (Asus Memopad 8 K00l). Nobody even on XDA posted ROM for Android 4.4 or higher. But: I can install Android Nougat on my laptop and it surprisingly works without any issues. Why is it so difficult to install it on some random tablet device?

Did you install nougat on a virtual machine?
No, it was installed normally as dual boot with my windows 7 (on separate partition of my HDD)

Every handheld device like a smartphone or tablet has its own hardware.
The kernel, for example, needs to be programmed about which drivers to load.
And most of the time, each device has its own drivers.
Each ROM is built for a particular device, that's why one ROM which works on one tablet does not work on another.
But in case of large devices, like laptops, they are designed so that any kind of OS can be installed upon them according to the concerned person's needs.
There are operating systems which work only on part of a computer chip.
These OSes help in installing almost any OS in a laptop.
The same are probably not available for handheld devices like tablets

Miracast sink application for Android 9

Hello everyone,
I have an Ugoos X3 Android box, on a stock-Ugoos Android 9 firmware, and it lacks a working Miracast sink application.
By "Miracast sink", I mean an application that will allow sending content to the Android box (not sending content from Android to another device [such as TV]).
I know some other boxes, such as X96H, do have a working Miracast sink application, but I don't know where to get the APK file of this application.
And I tried the "AirScreen" app but for unknown reasons it does not work with the Miracast protocol (others are OK), saying that Android Miracast feature has been dropped by AOSP since Android Oreo (which I doubt).
Do you have a solution to this problem ?
Cheers !
Solution non exist, in >my opinion<.
