I got it!
I checked this guide out (google translated, cause it's not in english)
The SP flash tool on above link is Chinese tho so I downloaded the Flash Tool provided here instead:
In summary, I downloaded the drivers, SP Flash Tools, and the 2.9 file and followed the guide on the first link ....btw I don't have an SD card installed on my device
Do note I flashed this at my own risk tho but it was fairly easy and successful. I was back at 2.9 and now updated all the way to 3.8
