I think the video went members only now (YouTuber: Ginger Gaming Mentor Nvidia Shield TV Pro 2019 Boot Loop Repair (Recovery Image) https://www.youtube.com/watch?v=qc4m2Hfd4HY Try this one: https://youtu.be/9yHvOotwRjw or here https://techunwrapped.com/nvidia-shield-tv-how-to-downgrade-back-to-version-8-2-3/ Honestly, I think I just got lucky, it took a few tries to get it to start.

The pointer shows if you're just navigating the Shield's OS, but it disappears in the emulators... I'm still using mame4all. If you go into settings (P1 button calls it up for me) you need to click the box for Nvidia mouse support to get the trackball working. Hope that helps?

Ok, I bit the bullet and did the downgrade. Success! Just a few observations: What drove me to it was that the update also broke trackball/mouse support in mame4droid (with the Atgames Gamer Pro, probably with a regular mouse too). Oem unlock didn't take 2 hours - the entire process was actually under 3 minutes once I connected to the Shield properly. I used Win10 Powershell (so you need to add .\ before the fastboot commands) I used the crappy 2.0 USB A to A cable that came with the Gamer Pro and a regular old keyboard (I did have to plug and unplug them a few times to get it actually connect). I think the entire process is just finiky and less dependent on what cables or keyboards you're using.

You are brave! I started, but couldn't get past 'fastboot oem unlock'. Terrified of bricking the stupid thing, something isn't jiving. And, all the online instructions are a little different. Also, the warning of the 2019 Pro taking up to 2 hours to do a wipe sounds scary - we have sudden power outages around here, not risking it. Did you downgrade a 2019 Pro? How did it go for you? Flashing game systems never took THAT long!

I'm sure MANY people will be VERY grateful! I just put in over a month of work making tweaks to my collection, the prospect of never playing it on my Shield is very sad, I just got it to where I was happy. I appreciate your effort. Thanks!
