Anyone had a chance to try the new firmware yet?

I'm hoping to try in the next few days.

I've just flashed v727.

I was on v715 which I was very happy with. Have flash via the Local Update option as its OTA.
Updated well, no issues. at all experienced.
My use of the TV is 95% with a PC so only tested that so far. Works just as well, I dont see any additional settings or anything out of the ordinary, so dont know if anything has changed with this release.

Will keep using this and revert back to v715 if find fault with it, had only tried one other version between these two and wasnt happy. v715 is my benchmark, v727 appears equivelant so far

v727 on C815

Picture is smoother, tho I notice a few more artefacts (less background processing I'm assuming).
Overall I'm happier with this update for the smoothness over previous versions.

I do use Apps within the TV, Youtube/Kodi/Plex/Disney/Netflix/Prime, all working OK.

That said - Plex still assigns the wrong audio channels for generic 5.1 streams, so use the plex plugin for Kodi instead to get around that.

I don't understand, both your posts. :rolleyes:
With OTA can update and downgrade from any version, same as with IMG file.
Benefit of OTA is not loosing apps and data.
With IMG file loosing all.

I appreciate (or at least I hope) you may be trying to help (despite your impatience that appears to come across 🙄). I'm fine with not being able to use the OTA method (for the record, that ability is broken on my TV following update to 722 and running a de-bloat script - my choice). In my original post, I was only asking if anyone knew if 727 was available as an IMG, if the answer to that is yes or no then that's all that's needed. 😀👍🏻

Lost the ability?

Are you using a FAT32 formatted USB drive ?

If you do flash an img file, the OTA from local function should start to work again (unless you have a hardware issue)
It's an issue with the TV after I ran a de-bloat script which is preventing any OTA update, which didn't bother me until trying to update to 727. Happy to wait for an IMG file to become available 👍🏻

Are you talking about OTA network auto update or OTA zip file manual update ?
Again,
same as IMG file, you can use OTA zip file for manual update.

There are the 3 methods for OTA update

Btw,
Reflash TV again with V722 IMG (or do factory reset) and all your "debloat mistakes" will be gone.

I debloat my C715 100 times, never happen to me.
Flash any IMG file (or OTA zip file with IMG method) and don't run unproven debloat list.....

Flash with OTA file:
Download V727 OTA zip file and zip file copy to USB FAT32 formatted.
- Insert USB in TV input (be sure TV recognise USB)
- Off TV (by long press on remote or unplug from power socket)
- Press and hold TV power button (if you unplug , plug back power) until flashing start.
- Release TV power button and wait TV to be restarted.

Yes, you are right...OTA will never change present changes....(but at least can update !)
IMG will do ....(y) ...or from your list, what you disable, need to enable (reverse) again.
I don't follow any list, as I doing myself.
For debloating ,I using ADBAppControl from my PC.
So, anything I wrongly disabled, I can enable back anytime.
And I can see what I doing....
Samples attached....

    Another Argentinian here.
    As I got tired of waiting for the OTA to appear, with my adb logcat running, and it never did ...
    I thought: "why don't I edit the ota v213 url to see if it works?", and it did. :p

    I have a 75c815k (uk) and have just updated to V715 android 11 software, I was previously on V645 the current official TCL European software and had spent many many hours tweaking the settings to get what I consider the best picture quality to suit my taste and eye. My son has an LG 77" c1 oled which cost him roughly 4 times more than my TCL and whilst my picture is not quite up to his with my settings I think it comes very close and thought I would share them if anyone wants to try them. I like quite a vibrant picture so have used the standard mode with the following settings for SDR ( in movie mode the same settings give a slightly softer look)
    Brightness/backlight 45,
    Contrast 90,
    Black level 40,
    Dynamic contrast off, black stretch off, brightness+ on, local dimming low, gamma 0
    Colour 48, tint 50, dynamic colour on, colour temp -1
    Sharpness 50, digital noise and noise reduction off
    Gradation clear (not on V645) low
    Motion clarity on, led motion clear off, judder reduction off
    Expert calibration settings untouched apart from colour space set to auto.

    My Hdr settings are similar although brightness and contrast left at 100 and colour pulled back to around 46
    Dolby Vision left alone.

    These settings were originally set on V645 but seem ok with V715

    As with most things picture quality is subjective but these settings I believe would give a much better baseline to the out of box settings which are way overblown in my opinion.
