Hisense Firmware Repo by R-T-B First, a word: So yeah, anything you flash is your own responsibility. Make sure it matches the model number of your TV exactly, and I can't/won't be held responsible for damages. If this bothers you, get out of here and call HiSense. Second, some instructions: In this page you will find folders. Inside each folder (named for a model of TV) is a readme, much like this one. Those readmes contain firmware information to help you choose which to flash, and instructions on how to flash each file. It really couldn't be made easier, I tried. The folders also might contain some misc .txt files the readme may reference. You don't have to read those unless relevant to you. But seriously, do read the readme.txt. That being said, you can hurt your TV with this. So try and be sensible. The readmes usually tell you what you can/can't do with a model. I plan to expand this over time. As of the writing of this readme, we are actively seeking firmware from users. If you have any, please forward it, along with all the info on it you may have, to R-T-B at https://techpowerup.com/forums/ I will accept any TV firmware that is a Hisense and flashable in some situation, no exceptions. Just contact me. I'm a nice guy/frog. Really. -RTB
