Can you change from V277 to R166? Tell me how to do it if you can? and tell me if there is a significant difference and if it is worth it. I am from Spain and I have a tcl 55C725. I see on platforms like Netflix the image very rare and not very fluid as a lack of refresh rate. Sorry for not having written in English before.

R166 is IMG file and can be flashed on any other version.
Search in this thread how to flash IMG file (many times posted).
V277 is Android 11 and R166 is Google TV system.
In post #712 you can see versions which can be installed.

V407 IMG first, then V414 OTA update.

T615T03...V4xx firmware version will be also for 2022 models, as C735, C835, C935
Thanks, i did it as you suggested without any problem.

Unfortunately, the HDMI problem is back (no Dolby digital plus).

So far,
V83 : no Dolby digital plus
R74: Dolby digital plus working properly
V407: no Dolby digital plus
V414: no Dolby digital plus

So only R74 can output property Dolby digital plus :(

So I've decided to return TV back to shop, V245 firmware keeps showing random vertical lines which requires TV to be unplugged from mains. Thank you all for your help :)

It's seems to be problem with the V245 build. Related to powering back on using Quick Start. Vertical lines and no image requires a power off to get the image back. You can just install another GTV build like R166 which works fine or just disable the Quick Start option under the Power Menu.

No V245...is V254.
Originaly this firmware (V254) is for S546 N.America model, so any diviation in other TV models are normal
and will not be 100% fully functional.

Since last week in some countries C728 and C825 models, selling with Google TV out of box.
On box itself, is cleary stated ...Google TV (no more Android TV).
TCL placed on server V8-T615T03-LF1V414, as official network Auto update.

Hello, does TCL 65P725 (R51MT02, V277) support VRR? Based on Australia and New Zealand specification sheet, it does support the feature, but my TV (bought in the Philippines) isn't showing any setting related to VRR. I'm trying to use it for gaming but the screen tearing is quite terrible.

I recently bought the TCL P725 75" in Australia (local stock from a reputable local seller).

I also bought the Nvidia Shield TV Pro (2019) from the same local seller and a high bandwidth HDMI 2.1 cable to connect the TV and the Shield.

Everything is fine except when I try to play Dolby Vision content on the Shield and I get black screen but with sound. I get the icon "Dolby Vision" at the top but screen is black. I've searched everywhere (including these forums) and noticed some people experience the same issue as me but seems noone's had a 100% guaranteed fix.

Does anyone know anything I could try or just give up and use the TV's native apps to play DV content?
Hi @jedwvv23, is VRR supported on your P725 unit, if yes, how do you enable it? I have one but can't seem to find any information regarding this. Thanks~

    Back from the assistance shop with a BRAND NEW GOOGLE TV.
    They gave me a brand new 43C725 TV with GTV firmware installed.
    Even in the box it was written Google TV (previous box was android TV).
    Anyway they told me TCL are changing panels because they are having this kind of issue.
    Let's see how this tv will be

    Here are some photos of 43c 275 firm 468 GTV with quick start
    Same as mine.
    TCL will contact me to arrange an appointment for technical assistance in my home.
    If you have the same problem, change the tv at the shop or contact TCL immediately.
    I will update this thread [or maybe open a new one] as soon as I have news.

    Hi Stasiof, can you fix the Netflix UI with blurry text and subtitles? Netflix app is more blurry than other brand Google TV/Android TV, thank you so much!
    I am not TCL firmware developer..... :ROFLMAO:

    On other hand...no TV model, no firmware version noted from you.......so how ?

    When did you buy your TV? I bought it at the end of January, and I experienced all these issues after a couple of months.
    Back then I had ATV fw. But still had to disable quick boot to get the TV working.
    I asked for assistance on Thursday, June 9th, they asked me to send some pictures, and yesterday (Friday June 10th) they wrote me back. They said a technician will call me back to arrange an appointment in my house.
    If you have the same issue, try to write to TCL. I think this is a hardware problem.
    And I don't want a TV that cannot be updated.

    It's definitely a software thing as it only started happening on recent updates. As @solman67 says V435 works perfectly and I've been reverting back to it each time. On the TCL Telegram chat there are quite a few people with the same issue so let's hope they get it fixed. We just need to hassle customer service 😉

    About quick start failure 43C725, this morning the service center wrote me they want to see an photo of the actual software i have installed in my tv. I told them that with the last 2/3 updates of GTV, in my case, the quick start does not work and the tv starts with the stripes. And that now i am in version V435 and that the quick start works perfectly. They told me that they will translate this information to the technicians to find a solution. In my case i will keep the tv and not change it because i am 99% sure that its an software problem and changing the tv will not solve it. Lets see what happens. If any of the here affected has news, please inform. Thanks!

    There are certain regions where OTA is not available for years & neither on TCL local support. AP region hasn't. NA & EU are lucky though where updates are available via OTA or local TCL has it on support page.
