V715 OTA file working without any problem.
Describe how you try to update.....
Sometime other USB help.
I had a similar problem with the V715 file , unzipped then tried local update in settings and then unplugging and holding manual on off switch, screen started to respond and then yellow led's lit and then stopped. Powered off and back to normal. The usb I am using is same as one as used to load V645 (wiped)

Hi Folks, with V715 Android 11 on C715, how do you guys rate the Dolby Vision content? I feel it is blushed a bit on DV Dark mode setting! I prefer not to meddle (recalibrate) DV settings unlike HDR since DV provides dynamic content based on the actual scenes in a video. I moved from R114 which I feel gave me a better dynamic picture quality for DV Content on darkmode! Any comments or suggestions?

I downloaded V715 OTA file again and transfered to reformatted flash drive, left file zipped and tried local update but stopped after 1 second with message " the validation of update package failed and system update stopped" ?? I am obviously doing something wrong still but not sure what any help appreciated.

Try other USB FAT32 flash drive or other TV input.
At least you are on right way....with OTA zip file

What do You mean by that? V701 updated fine and worked as a local update unzipped on the very same flash drive. Since I am not the only one with update problems with this particular OTA, odds are there is something off with the update itself.

Like I said earlier, when unzipped V715 OTA is missing some directories and files compared to V701 OTA, and have downloaded V715 twice just in case.

You are first one who UNZIP OTA file and update by local update.
Never heard about this before.... :ROFLMAO:

I update 5-6 times with ZIPPED V715 OTA file, with no any problem.

Attached.....V701 OTA and V715 OTA.......NO files missing.....:rolleyes:

Guys on C715 once I enter into advanced menu (1950), I see the color temperature is set on Normal, I use the left right cursor on remote to change it to warm and then warm2, but not able to lock it on warm or warm2,. When I press the menu button to go back and then revisit the settings the temperature stays as Normal? Any idea on how to set it to warm2 or warm?

I really appreciate the assistance you have provided so far but I am still struggling to update to V715, I have reformatted my usb (fat32) and re-downloaded the OTA version on the link you gave me. I am not the most technical person and whilst I am good with tv's am terrible with computer tech (I am old chap) I use a chromebook to download and transfer to usb, would this be the cause of the problem? I downloaded 1st attempt on wife's windows10 laptop but it is old and very slow and keeps failing when trying to download file. Sorry for my ignorance! Again thanks for your help and patience

Did you try other USB stick, as I asked you earlier ?
To check V715 zip file checksum .look at post # 3605 above....

You see that only characters who do not have the basic knowledge to update the system and hate to read the previous posts appear here, but they torment us with one and the same questions. I don't know I haven't used p114, on my 65c815 dv it looks good on v715. Which option do you use light or dark?

I had the same issue with the OTA file from the link in this thread and thought it was my USB drive, so I tried 2 other sticks to no avail. Package verification failed when trying to perform local update.

However, I downloaded the same OTA file from another source and it installed without problems, so there might be something else to this, as there are at least 3 users on this thread who have replicated the issue.

When you say another source do you mean a different computer/search engine or different download location?

I think the below is the reason - but if others have better ideas please share.

This appears to be the new behavior - if the microphone is "listening" then the LEDS are off. If the microphone is NOT listening the LED's are annoyingly shining nice and brightly.

I have just bought a Samsung hw-s61a soundbar with Alexa built in which has the same behavior - LED is shining brightly if you turn Alexa off but it is off if you turn listening on.

man, I had to register to thank you
I got a C725 this week and I was going nuts abt those damned lights.

also, I wanted to extended my appreciation to stasiof and his firmwares.

Hi
I have upgraded my P8M to V715 (Android TV 11)
Android 11 locks the ../Android/data/ and ../Android/obb/ folders
That creates problems when Copying, Moving, and/or Editing files within them
Or with some Apps that save files inside ../data, for example Opera, now it doesn't save downloads in ../Downloads, and those downloads can't be accessed, nor moved to another directory.
Another app is Kodi, when you want to edit your settings, etc.
On smartphones, with Android 11 or higher, there are several file managers that allow access to them and make modifications
None of the ones I've tested work on Android TV 11.
Anyone know any method?
Tks!

    I'm sorry, no DTS too. I'll edit the text.
    About Atmos, of course it's not, my receiver can't decode it too.. But the audio is working with a perfect channel separation in a 5.1 environment. How can it work? I don't know. Give a try to Tidal and test these Atmos content.
    Atmos is a not audio protocol, but a extension feature. It is carried along DD+ or Dolby True HD, which are indeed protocols.

    And is mandatory that every DD+ ou DDTruHD stream have an old DD 5.1 stream, inside it. It's used to send, to the receiver/processor, the old DD 5.1 stream, whenever the handshake between source and origin check the receiver can't process/handle DD+ or DDTruHD. Or the cable data can't handle it. SPDIF (toslink or coaxial) and ARC can't handle DDTruHD. ARC can handle DD+. Only E-ARC can handle everyhthing from TV to the receiver/processor.

    So, im this case, the audio streaming is downgraded to DD.

    But, as I said, on my TV Semp SK83000 through ARC, DD+ only works in bypass mode. In auto mode DD is always selected, although my Denon receiver supports it.

    But this works only with mainstreams apps (NetFlix, Amazon, HBOMax) and internal media player.

    In V715 no surround options works, along with android media players like Kodi, MX Player, VLC.

    If I selected AUTO mode DD is displayed on receiver, but it's not a true DD signal. It's a downmix (and a bad one) from 5.1 to 2.0.

    Hehehe time to complete your speakers setup. I cant live without the surround speakers and I have a much more modest in-a-box ht

    I tried! But my small living room has no design to accommodate properly surround speakers cable.

    I tried to put them under the carpet, but my wife started to fill divorce papers, and I rolled back... :-D

    I have bought TCL C715 TV and it was running on older verison to which i upgraded to V8-R851T02-LF1V715 version, but its a lot laggy even lags while playing video on Disney or Amazon prime.
    Suggest me the best firmware along with link to download it for C715 model, where it doesn't lag while playing videos or opening apps.
    v715 is defnitely the smoothest and all in all the best software up to date. I tried every android 11 software and v645 android 9 software as well and there is no competition. Try reset all and reset shop settings and reinstall the v715 version.

    Hi guys,

    In Brazil, we have a rebranded OEM TCL called SEMP. SEMP and TCL are partners here and the SEMP SK5300 TV has the same V8-R851T02 firmware/board.

    I've updated a few days go from V660 (A9) to V715 (A11).

    My impressions:

    Pros:
    Image seems a little bit better. Better contrast and black levels.

    My Sony home theater is working at the same way before via ARC. Perfectly. I always use the AUTO mode, it passthrough correctly the Dolby Digital 5.1 in Netflix, Amazon Prime e HBO MAX. The ARC delay is lower now.

    Refreshed icons in interface like arc volume and others. Fonts seems more sharp.

    Cons:

    I believe that Android 11 is heavier than 9, it makes the TV a little bit more sluggish, marginally, but I feel. My emulator performance using Faster Open GL in EPSXE is the same as before, I still can plan play PS1 games in HIGH graphics at 1.5x overclock CPU PSX.

    Overall I think the update was a great choice since I didn't find any bugs in TV. A more recent OS can grant more apps updates. Thumbs up for TCL.

    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.
    Perfect. Thanks for sharing with us.

    unfortunately, no, I can't enter the main program, the led initializes as the main page of an android phone, without system, that's why I want to see if I can resurrect it with a firmware in img file
    Ah,ok,
    Has many IMG posted here, why didn't check a few pages back?
    Sample.... V715 IMG is in post #3512 and many more earlier.....
