You don't need help.. Just need to learn how to read thread first before asking for help.. Read back a couple pages.. Sure know how... Seeing as you just joined today, consider this forum etiquette 101 class.. Always read first for info before asking for assistance.. High chances, questions on your mind have already been answered... 

Nah, you haven't read the last few pages... Cuz if you did, you would have seen neocyke's post on how to get apks installed on the exact same firmware as yours. Which also happens to be the same firmware on mine too.. So probably the latest firmware at this time.. Just see the post before yours. No recovery or root needed... Now you know what to do & how to go about it.. You are welcome. 

It's actually quite simple. You will need a keyboard and mouse. Usb or airmouse one.
- Use the browser and go download the apk you want to install. Sites like apkpure or apkmirror work best.
- Try to download as usual until you get the "Sorry" error.
- On the page you're on should be a link for failed downloads.
- Use mouse and long click on it.
- On the menu that appears choose Save link. You should see Starting download appear briefly on screen.
- Now, using the keyboard hit Ctrl+J and you will get the stock droid Download Manager.
- Wait for download to finish and click on whatever it is you downloaded.
- A familiar app install window should appear. Rest should be self explanatory.
Rinse and repeat.

Do note that installing just the playstore apk doesn't do jack. It won't open. Working on figuring that one out..
Hmmm. Then that update.zip might be gapps along with some other hypptv stuff. Gonna need to get one to test after rooting this box and replacing the recovery.img.. Thanks bro.

You are correct... Then just leave the check box disabled... Checked mine and if you enable the check box, the box does a quick check and confirms that we are on the latest firmware. So leave it unchecked.
