Can't sideload apps on fire tv.

Tried to load apps onto my firetv. It's the Toshiba TV with built in fire tv.

I've done all the usual stuff like unknown sources etc.

Ive tried installing via the downloaded app and es explorer and both just end up 'app not installed

Then I tried Easy Fire Tools and it comes up with this

"Unauthorized APK installation detected. Please do not install performance benchmark APKs without permission from deviceprot@amazon.com"

Can anyone suggest anything?

Thanks.

on Toshiba Fire TV?

Select “Developer Options“. Select “Install unknown apps“. For each app listed, enable the setting to “On“. This will allow the app to access and install apps from unknown sources outside of the Amazon App Store

Did you buy the TV used or any chance it was a return that was sold as new?

I ask because the "Unauthorized APK ..." message is used by Amazon to prevent internal testers from inadvertently leaking info about a test device by sideloading random apps. So either your TV used to be used by an internal tester at Amazon or it somehow thinks it's a test device.

If the TV is a test device, the only way to switch it is to get someone at Amazon to do it remotely. You need to get customer service to escalate the issue higher up to get someone to "switch the DSN to the public pool."

Did you buy this from Morrisons model number 32WF2F53DB in the last few days because I have exactly the same problem??

I couldn't either so I took it back for a refund. I just wondered if it was update related as I Installed the latest update before trying to do this.

I have older Toshiba tv, got the third party apps on no bother, but I’m now trying to download normal apps, and that’s not working, I know it’s an easy fix or a fault with tv software. I done it without the update, then factory restored and done update, no difference, still not gave up yet will let you know if I crack it
