Please help.

I have 55c715 and i try to update android with 645 version. I selected file, verification went ok and tv rebooted. After that screen went black and led is blinking. Nothing on screen. I left for an hour and nothing on screen. The i turn tv off and on and screen is black and led is blinking - not pressing anything. Blinking even without USB inserted. Then I tried several Update.img on USB, push button for 10 seconds but screen remains black and led is blinking. No light on usb drive either. TV is only 14 days old.

thanks for your answers
Pitty you....best is contact TCL.

Hello.
I’m Sai NiYom from Myanmar.
We don’t have such things as professional TV calibration here.
We have to make our TVs’ color look as good as possible on our own.
My recent TV is TCL P8M Android 4K TV which I bought one and half year ago.
I was very satisfied with it until I messed up with white balance 2 point values while playing an animation film in HDR.
I reset white balance, did factory reset, upgraded the firmware and did everything I could to get the colors back to normal.
But the colors are not the same as they used to before.
I’ve been struggling with it for almost a month now and I would like to ask for your kind suggestions.
Thank you so much in advance.
Try again factory reset and afier flash IMG file...maybe help.
Edit:
You didn't play with "Service menu"?

my 55P8s uses the GMT+0 (UK time) since updating from stock firmware, and this resets to that time zone every time I turn off then turn on the TV. any solution for my time zone to persist (GMT+8/UTC+8)?

Hey team,

I am trying to flash this on my 50C715, the update is not recognised by the TV.

I have tried the full zip and also extracted it and neither will be detected.

In root of USB, its it the ziip or the extracted folder? Does the name of the folder or zip for this one need to be renamed maybe? The name of the download is V8-R851T02-LF1V649.019097.zip


thanks

I would also like to share a tool to debloat TCL that I have scavenged from 4PDA. If anyone knows Russian alphabet, could you write a working tutorial for it?

I have not actually used R709. I've gone through v389 which was atrocious, v645 which improved a lot of colour bleeding/blurring, and now v649 which I have to say, is another improvment and is at the moment, awesome. I never had the HLG issue, or could not identify it if I did.

Since update to v649, I've used the PC and streamed 4k HDR Netflix (Defenders and Lost in Space). The colours are more natural but very colourful without being over the top, no bleeding at all, and us noticeable sharper, clear and more defined. Specular highlight very sharp and detailed.

It could be all imagined, but it does seem clearer.

I wanted to return the tv after a week, quite happy with it now

    Be advised!

    I would suggest NOT to install this Android11 update yet, wait until bugs are sorted out.

    I have 50C715

    Firstly, great to see Android11 on its way! Awesome, cant wait for normal performance and functionality. Good job TCL and anyone else working on updates ;)

    Positive
    I have found that Auto Low Latency Mode (ALLM) is now available, I have not been able to test to see if it does anything yet​

    Negative - HDMI inputs DO NOT WORK
    I can not get my PC to display a picture. Have tried HDMI 1 and 3. The TV recognises the PC resolution but it can not find a signal. I also notice that the HDMI option for enabling 2.0 is no longer present in the options.​

    Digital TV channel scanning is not possible.​


    As most of use would be gamers on PC or consoles, this is not a viable update as cant play if you can not access the output of your chosen device. Im guessing DVD/bluerays wont work either, from what I can tell, HDMI is broken

    Trying to work out how to revert back to an earlier Android9 update, as I can't use my PC where I have the files lol. Lucky I have a work PC with me, just trickier..

    V900 works good on my TCL 55EP640...
    Thanks good.

    Its interesting then. 2 users having R007 (v900) working on xxEP640
    2 not working on xxC715
    1 not working in xxP615

    Is it better suited and made for only specific TV models? Eg just the EP640?

    The HDMI stopped working for me on this version as well... though my power on remote stopped working a couple versions ago. I had to use voice command. But then, voice command didnt work on new version. After downgrading way back to v453, my power still didnt work on remote. I tried repairing and unplugging tv, swapping batteries, even doing a factory reset and trying to pair remote in fresh setup flow... nothing worked until i found the exact process. I unplugged TV power, removed batteries, powered up tv, and did not place batteries in remote until TV fully booted (this was on TCL's troubleshooting steps) -- and it worked!

    Hello today i want Suggest & share TCL C715 settings for Xbox series x, at first never enable HDR for this tv disable HDR on xbox .

    also you need to enable in Xbox settings -- > ALLOW YCC 4.2.2 and use 10 BIT color depth this settings did not exceed hdmi 2.0 bandwidth also has less banding .

    tv setting must be

    SDR
    Game mode : ON for lowest input lag
    brightness: 100
    Contrast : 100
    Dynamic Contrast : Low or Hight ( I prefer High )
    local contrast : low
    Black stretch : 0
    Dynamic Backlight : off
    color : 45
    black level : 48
    Sharpness : 0
    color space : auto
    color temperature : -1
    Gamma : 0

    HDR : X not good for this tv

    with this settings tv gets darkest blacks as possible and brightest whites , picture are fantastic clear and 3 dimensional, fantastic result on forza horizon 4 and more

    I 100% recommend to try this settings on this tv and xbox if you want bright and Crystal clear image

    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
