See, Hisense TV's are generally pretty solid spec wise, but their firmware is all over the place. Some excellent, some alright, some downright awful, and they never ever list them all in a consistent fashion, generally only listing the latest one at their website (if anything). This archive is an attempt to rectify that.
Right now it just features all known builds for my personal TV, the 55" 55U8N, as well as it's other model number it was sold under, the identical 55U8K. But Hisense's are interesting beasts. They allow downgrading, crossflashing, anything really. Once you stick a firmware in and tell it to update, it will do it, no questions asked really. If you follow the right procedure anyways. I document those too.
So yeah, how do you use this? Start here:
https://glacialsoftware.net/FIRMWARE_HISENSE/
It's a real simple text based directory-like FTP style website (I don't have the willpower to throw anything better together, or the time to maintain security on anything more than static pages so...). You should probably start at the root readme.txt. Read the readme.txt's in each model TVs folder too and you can't go wrong honestly. The other .txt docs? You can ignore them unless something tells you to read them. The .zip firmwares? Don't touch those until told to. You've been warned. I won't be held responsible for your "I didn't read" stupidity. Sorry, but I have to say it.
So, enjoy. I'm actively seeking firmware from Hisense TVs of all shapes, sizes, and ages. If you have any plus any info on what that firmware does and/or how to flash it, please PM me and I'll try to add it to the listings!
PS: I actually still think this TV was a great value, but man, from my experience with this TVs firmware the past 2 days or so Hisense has some great specs that really deserve better software. The autoupdate is furthermore very cruel, activating an unskippable screen nearly immediately upon connecting to internet or wifi. I also have a guide on how to disable that for my TV, for the curious.
In short, I love this TV because it's a tinkering nightmare. But would I advise it to people who just want things to work? Uh... Hard to say. Probably not. Just keep that in mind. You can get great value with this brand, but it's going to be an uphill battle with regards to firmware fun.
PSS: If anyone wants to make these pages into a better looking static html thingy, I am not a webdev at all and would probably appreciate it. Not essential at all as the text pages do their job, just ugly to look at. Probably could use a WYSIWYG editor, but again, time...
