[Philips, Sony, TCL Android TV] stasiof:
You can try any T615T03 version.

Issue or not, that I don't know.

Btw, you can always downgrade with IMG file.
[Philips, Sony, TCL Android TV] hwolfe:
Hi, I have the same question - did you find an img file to downgrade back to OTA v399 or earlier? If so, I'd be very grateful if you can share what you used. I have a 65S546 that I upgraded from v306 to v813 using OTA method, and I've had no luck downgrading with an image that will then allow me to flash OTA to v277 or v399. I used an image file I found on telegram for v166 (or maybe r166?) which worked, but now when I try to do a local update with OTA, it says something like "no update file present, please insert USB drive with update file" Thanks!
[Philips, Sony, TCL Android TV] stasiof:
Must rename OTA file ,instead of V to R.

Btw, no need IMG file to downgrade.

Can be done with OTA zip file in IMG method.
[Philips, Sony, TCL Android TV] hwolfe:
Thank you! That worked like a charm (as you knew it would 🙂). Will I need to do this with all local updates henceforth? When I local updated from v306 to v813, I didn't have to change the v to an r. Anyway, thanks again, much appreciated!
[Philips, Sony, TCL Android TV] crazymark84:
Hi all,

I have 2 problems with my 55C725 (FW version v.231) (Region ITALY)

1) Disney+ not present and not downloadable from the play store, reading the various pages of the forum it seems to be solved with an UPDATE.

I also checked the TV menu for updates from Device Info but there are no OTA updates to be done.

Do you recommend that I proceed with the V.238 update?

2) Passthough audio playback on rear speakers not working with non-native apps

I configured the TV via optical SPDIF to the SONY STR-DE597P amplifier (very old but still works fine). Before TCL I was using it without problems with the old Philips 55PUT6101.

After doing all the various configurations I noticed a strange thing; Kodi doesn't play the surround back audio.

I went crazy trying so many settings both TV and amp side, but I couldn't get it to work.

(The sony has a blue light that if it comes on means it's passing dolby audio and in my case of course it comes on).

Try and try again, I've noticed that the surround back works perfectly from the PC (connected in HDMI to the TV) and also from the PS3 (also connected in HDMI to the TV); so 2 devices passing audio to the amp through the TV's SPDIF and not directly to the amp.

I then try the various TV apps and discover that it is most likely not a configuration problem but an app problem.

In fact, Amazon Prime Video and Netflix (installed natively) reproduce surround sound back perfectly, as does the native Media Video app of the TCL TV media player (an embarrassingly featureless app).

While Kodi and Disney+, Nova Player, MX Plater, Plex... installed by me later, do not play surround back audio.

(Disney+ installed by Aptoide TV)

Clearly if I set it to full PCM no problem but the surround effect is not as good as Dolby Digital AC3 or DTS.

Is there anything I can do to try and fix the problem?

Given the 2 problems, do you recommend that I upgrade to V.238 or V.256?

In addition to the download links in the forum is there any way to get the link or where to manually download firmware and maybe see the list of bugfixes?

Thanks in advance for your help!
[Philips, Sony, TCL Android TV] stasiof:
Hi, first of all , yes you need to update firmware.

Instead of here, you can found TCL links also on telegram...

{Mod edit: Links to Telegram removed. Oswald Boelcke, Senior Moderator}

No firmware on TCL official web page is posted yet.

You mention 2 firmware ....V238 and V256.

V238 mentioned is OTA zip file and V256 is IMG file, so not same way to update.

I hope you read this thread and notice that mostly no changelog is provided and how to

manually update firmware.

How many additional apps you installed on your TV?

If not much ,I suggest to flash V256 IMG file first, which will erase all your apps, but system will be clean and ready to update to latest V267 OTA zip file ,which do not erase anything.
[Philips, Sony, TCL Android TV] crazymark84:
Thank you for your help!

I've installed v256 IMG and anfter I've upgrade to v267.

Disney+ is fixed 🥳 but not work surround back like all apps installed manually from playstore

Unfortunately, Kodi\Nova Player still has no surround back😭😭, and doing the various combinations I have noticed some difference, in the sense that where before it was whistling (depending on the combination) now it does not whistle, or if from TCL I select "Transfer" in the audio options, before I got Dolby from Kodi with the light on now I get PCM, a sign that probably something is moving. Hopefully in the next updates they will solve this case.

It would seem to be an Android API development issue that happens often on TCL and Philips.

I've got a TCL 55C825 last update (V8-T615T01-LF1V072 > EU version if I'm right) and the remote voice is not working

(When I push the voice button once on the remote, it shows the google bottom on the TV, but does not react when I speak to the remote. If I push the button twice, it activates the TV Microphone, and I must yell to succeed been heard by the TV...)

Since I've got another remote with a microphone that works on my Android BOX, I tried and it doesn't work either.

So I suspect the firmware to be buggy, I wonder if other guys who own the C825 have more success with the voice search by talking to the remote ?

Also, am I correct in thinking that if I want to swap over to Google TV [GTV], I need an IMG file?

To be honest, I'm not sure whether to move to GTV or not. I have a GTV Chromecast and it's zippy compared with this ATV's OS, but that might well be just the difference in hardware.

Does anyone have the img file for update V8-R51MT05-LF1V306, so I can roll back an update? My TCL S546 TV just updated itself to V8-R51MT05-LF1V813, and I can't get chroma 4:4:4 to work anymore. On V306, all I had to do was rename the hdmi input to "Computer", and then put the TV on standby and then turn it back on, and the image would look clear once powered back on. With the new update, there is noticeable dithering, text looks terrible, and color banding is really bad. It's almost unusable as a computer monitor now.

I tried a bunch of stuff to fix it, like replugging in the hdmi cable, restarting the tv, changing the picture settings, checking my graphics cards settings, factory resetting, rolling back to older firmware that's still available on the TCL telegram channel, but nothing works. The only thing I haven't tried is rolling back to V306, which I believe was previously installed. Download links for V306 posted in this thread seem to be dead. Thanks.

Thank you so much! Downgrading fixed the chroma 4:4:4 issue. Now I don't have to get a new TV :)

For anyone looking to downgrade the firmware, format a usb drive using FAT32, copy the OTA zip file over, plug the usb drive into the TV, turn off the TV, hold the power button at the rear of the TV for a few seconds until the LED light blinks and the TV turns on, and it should install the OTA update.

I cannot comment on OTAs cause it never worked for me. For me the versions don’t matter much since I anyway use a firestick primarily. But this eArc issue on my S546 after upgrading to V813 was annoying.

I flashed the V418(IMG, not OTA) and that seems to have resolved the eArc issue.

V418

But i started to notice audio lagging when watching some programs for an extended period of time. So flashed V501 IMG file(not OTA) afterwards. Havent seen any issues since.
