I tryed to update my C635 for the first time manually with OTA file V559, but whenever i Try to update local or with power button on tv, message appears saying there is no update avalable or don't find any update file on USB drive...
Tryed to re-dowload some times but, it fails all the time.
Why this happens? Any Ideias.
TV came with version V508.

Can you be more specific? what should I looking for? file system is FAT32
I don't understand what's wrong. The software is for my TCL C635 and when try to update says no update found...
V559 OTA zip file is on USB ?
TV recognise USB when inserted ?

Tv setting...software update...local update.
Try other TV USB input.....
Reformat USB again or try other brand.

Yes, extrated the zip file on USB, and the usb is recognized when inserted on port, so it's why don's understand it's says no update found.
Reformated usb drive,inserted also in the port 3.0, even with a previous update the V523, but get same message that no update is found.

May it's a problem with pen USB, will try again when get a new pen from other brand.
What pen is best, what brand do you recomend?

You don’t extract the OTA file, you put in the usb as it is.

Yesterday i saw this in Telegram :
New TCL T615T03 Google TV Update available in V511.
TV models .......C735 & C835 & C935.......(C728 & C825)
V8-T615T03-LF1V511.000744

V511 OTA

Link

build date= Apr 11 2023

It starts to get very confusing for me with these numbers, latest OTA was V562 with same build date, now V511...which is the newest ?! No release notes of course, as always...worst support ever in my experience !

Very simple.....
V469...V474.....V503.....V511.......2022 TV models (e.g C835)
V558...V562.......2023 TV models (e.g C845)

As is same platform.... T615T03, can be installed on last year (and 2021) models.

How do I disable weird backlight change. When I watch netflix in dolby atmos, changing scenes brightnesses the subtitle and scenes. I mean subtitle is sometimes full white, sometimes greyed outz It is annoying.

I did that yesterday without any issues. From v508 to v559 OTA via local update. Must be an issue with your USB stick...

Ok, but what if a 2023 models firmware is installed on 2022 model, like C735 ? Is it a bad idea and should we stick to the regular one, although it seems to work normal ?

The problem, was that I extracted the zip file to the usb stick, that was my mistake, now all ok, sorted out. Updated to V559 without any problems.
All ok now.
I see that the is a new V560 update, althoug this is an IMG file. Any big improvments with this update?

Hello all. I'm a newbie here and I'm trying to find a solution to my problem.
I recently (few days back) bought a 65p635 google TV, and everything works fine except from ARC that is connected to a Samsung 5.1 home theater. My previous TV, a Samsung UE55HU6900, was working perfectly with it.
The problem is that although the sound passes through ARC, the audio channels aren't working properly. While testing with Dolby 5.1 audio test or Netflix test patterns, the center channel gives audio to the rear speakers also, the rear speakers channels give audio to the front also and the sub doesn't give audio at all.
I tried all the settings available. Enabling CEC, disabling CEC and sending TV audio to ARC from the menu with passthrough and auto setting. I disabled also eARC (a feature the receiver does not have). All give the same result.
I updated from v63 to v69. Made HDMI reset and software reset but to no avail.
I also tried optical cable (just for testing because the optical is used by my PC), and the channels are working fine! But the audio comes from the TV speakers also. They cannot be disabled in the menu and there isn't an option to exclusively select optical for audio output .
Does anyone have the same issue?

You need to calibrate your AV receiver by the sounds of it.

There isn't anything to calibrate to the AV receiver unfortunately... You either enable CEC or/and Audio Return Chanel. It reproduces the audio the tv sends via passthrough arc (it can decode Dolby Digital, Dolby Digital Plus, Dolby True HD, DTS Digital Surround, DTS 96 / 24,DTS-HD Master Audio)

Hi. So I installed V562 on C735. Since this seems to be update for newer versions of TV, is it possible to switch back to normal V511? I don't think firmware updating supports downgrade to lower firmware version. Thank you for response.
You can download with any IMG file (T615T03).

    @spl_decibel ok, you have R51MT05, so the latest version is v573. It is probably not officially made for P635 as it is primarily intended for 2023 models, but it should work fine (at least it works fine on C635).

    Hello, I have a C935, how can I mark favorites in the TV channels? Excuse my English.

    Assuming you're using the latest v562/v582 firmware - hold OK button until info screen appears, there's heart icon to mark favorites.

    Good morning guys. One question: I have the C835, I currently use FW v582 (latest update). Everything is working great, my consoles, nvidia shield, etc. However, because my TV is a 2022 model (C835), would the FW v511 version work better? I mean, colors, shades of black, etc? Thank you in advance for the response.
    No, v511 is hot garbage - much worse UI, absolutely terrible eARC/CEC and it's not faster or anything. Image quality doesn't seem to change either

    With the latest update v573 for c635 the issue with Dolby vision has solved

    @Sagi.f So you can try upgrading firmware to a different version. I have TCL soundbar connected via HDMI eARC and I also sometimes have issues with it. Recently I was using V523 which was quite OK, after that some later version broke it so I returned to V523 and currently I am testing the latest V573 - it seems it sometimes disconnects+reconnects the soundbar sometimes when nothing was playing, but it was OK when I was watching a movie.
    Sometimes it also helps when you power off the TV and the soundbar (or receiver), unplug the cables, and then connect it again.
    Try also powering off and on your receiver when TV is on.

    Hello, i have P635 50" (TCL G03_4K_GB_NF)
    is this last firmware version?
    V8-R51MT05-LF1V573

    Many Thanks
    Post your current firmware version

    No one test the beta version..
    This is a forum for people who do exactly that. Developing and testing different firmwares and other forms of software development. If people didn't do that then you wouldn't have a forum to whinge on. Everybody is different and everybody has different things they enjoy doing, so I'd say yes there is people that care about it despite the fact that you may not.

    I have 50c735 europe_pl (bought and use here) first set up update firmware to v477, but that's it, no more updates to do, it says - nothing to update. I know that there are few next updates so I decided to do update by myself, but to be sure and safe, just for know I just update with v496 OTA, of course reset shop, reset all and after that full factory reset and configuration of all Google TV once again with all apps etc.. Hmm.. I don't know if this update give something new, may be some functions or naming of it, may be little smooth feeling, but rather little not many. Hmm, but what I noticed, after update the screen is more more red.. and maybe pink moreover in some movies/ apps so I have to change white balance in expert mode 2 points and red boost set to -16 and blue -2, now is very good, but.. hmm someone also noticed it?? Some said here that the Dolby Vision is repaired now, but don't know what, maybe is more smooth, maybe - ok, but still the problem about @OnyOnaki said above actually exist. I can't say that is brightness lag, its like a delay in led backlight software saying about reaction. Hmm Im good with that to be honest, it doesn't annoying me, but some in my family said that is really not cool. Hm.. in my opinion this is a dynamic hdr so..., but yeahh.. it could be faster... To avoid big jumps of brightness I set bright preset and gamma -1, everythings OFF and dynamic mapping on OFF [but to be honest this option is really good to have ON, because of details that he helps you to see in very white scene, but.. also makes more work to brightness regulators]...

    I think about v501 flash via IMG and make completly fresh instalation, but.. don't know if it make sense. I think the main problem is CPU and everything we say its about him. TCL make not good move with making money on us who don't need big-bigg screens and they implement ****ty realtek CPU inner <50 inchs. Really sad, because these TV to be honest isn't the cheapest we can buy, but maybe some updates helps us.

    Maybe someone has calibration settings for these C735 SERIES to 50 inches etc.. screens, I mean of course calibrated with sensor, not on eye, because on eye I also did that, I've got good eye hehe, but if someone has settings made by pro, it will be be nice to share with us.

    Someone test v501 on c735? I saw there isn't at v501 OTA so.. I don't know if it is safe.. and if it is worth to update.


    EDIT: UPDATE ABOUT FOR ALL OF US WHO HAVE DOLBY VISION BRIGHTNESS PROBLEM, THERE IS A WORKAROUND SOLUTION AND SOMETHING LIKE A GOOD NEWS.

    I found these instruction here on xda in other thread with beyond TVs:
    1. Activate Quick Start (EVEN if you have this option ON, just do TURN OFF AND TURN ON THIS OPTION once AGAIN)
    2. Turn off (hold power button on remote control 5 seconds and say YES/ OK to turn off question and unplug the TV and of course after 10-15 sec, plug in powercord to TV again)
    3. Turn on the TV
    4. Let it load all the GTV UI
    5. Turn off the TV with the remote control button (but not completly, just one short click - to quick start standby mode)
    6. Turn the TV back ON with the button on the remote
    7. Put the movie or series with Dolby Vision
    8. Enjoy, finally, the movie or series without brightness changes in the scenes

    And if you always use stand-by quick start turn off turn on method od remote control, these will be work. If you unplug TV or you lost power on TV powercord you will need to do that ALWAYS ONCE AGAIN AND AGAIN [DON'T SKIP ANY STEP, JUST DO THAT ALWAYS THE SAME WAY]. Don't test it how it will be working after few days and making a mess with apps etc.

    And these is that good news - its only firmware problem, not a hardware, but the question is if the TCL knows about that and has a will to repair that in next updates. Some say here that the V501 repair that. Don't know, im on v496 now after manual OTA update with V477 stock firmware, but on these two version, it was the same problem. Maybe I will try to V501 IMG full firmware flash with reset all and reset shop before, and factory reset after flash this IMG and I will also report if that helps or not, but to be honest I think TCL don't know how to repair that. I know one TV from my country which is on the market warranty Service and 7 days after still we don't know what will be done in this case. I also forward these news and instruction how to workaround these problem and maybe service will contact with TCL SUPPORT and MAYBE THEY forward this information on the next steps, but to be honest in these budget - the only we can do now is to have hope that they will still work on these platform, it's 2022y model so maybe... Don't know, will see.
