Works perfectly coming from R166.... Thanks
[Philips, Sony, TCL Android TV] JPelegrin:
¡HI! I bought a TCL C725 back in october and Im having some issues since then. The TV is so slow when working with some stream apps (especially HBO Max). In fact sometimes it doesnt work at all and I end up streaming the content from my smartphone. What could be the reason? Firstly I thought the cause was my ****ty internet connection, but recently I've upgraded it to optical fiber and nothing changed. I also tried installing again some apps but that did not work either. Now im thinking maybe I got a defective TV, what do you guys think?

I also tried to update my firmware, like @stasiof told me, but TV says I already have the latest version.

Thank you so much :)
[Philips, Sony, TCL Android TV] stasiof:
So how you try to update ?

Give more details, which firmware and way to update.

You should read posts here, to know better what's is going on, how to update,etc....

Edit:

Go to setting...About ..you will found your firmware installed version.

Easy for you, is to look for V277 firmware here in this thread , download and copy zip file to USB.

Insert USB in TV, be sure TV recognise your USB.

Then go to Software update in setting and chose local update.

Do not touch anything ,till TV reboot in Home screen.

Voila done, you have latest firmware.
[Philips, Sony, TCL Android TV] deltacreen:
Is there a certain order you have to apply the updates? My C825 is now V082. Can I just apply the new V414 OTA straight or do I have to move up to it with previous firmwares? Like first V407 and then V414? Thanks for the help!
[Philips, Sony, TCL Android TV] JPelegrin:
I followed TCL website instructions and my TV says that I already have the latest version of firmware. My model is 50" and im from Spain if that helps. Now im gonna try installing V277 manually. Thanks!
[Philips, Sony, TCL Android TV] stasiof:
Your firmware is V8-T615T01-LF1V082.

T01 is Android 11

Firmware you want to install is V8-T615T03-LF1V414 OTA file.

T03 is Google TV

So, to change T01 to T03 need IMG file V407 (also T03), to flash first, then update with OTA V414.

Since V082.......

I have a 75-S546 that is getting black screens whenever I play Dolby Vision content (from Amazon Prime, plex, etc). This happens only from my external device (Shield Pro 2019.) Already tried multiple certified cables.

Everything else is working

Firmware version: V8-R51MT05-LF1V254

Does anyone know if installing a different version will fix this issue? Or are there known issues with this?
[Philips, Sony, TCL Android TV] stasiof:
Is this happen with previous firmwares ?
[Philips, Sony, TCL Android TV] Cosmos58:
I just got the TV put in yesterday. This is the only firmware I've tried and I think it is the latest from what I gather on these posts. Although it is a little confusing since the version numbers go out of order
[Philips, Sony, TCL Android TV] stasiof:
So,what has been previous version installed ?

This what I asking.

Or your TV came with factory firmware V254 ?
[Philips, Sony, TCL Android TV] Cosmos58:
Oh I see. When I started up the tv it updated it's firmware automatically during the setup process. I am not sure what it had installed when I took it out of the box. It's only ever had V8-R51MT05-LF1V254 since I went through the initial setup
[Philips, Sony, TCL Android TV] stasiof:
OK, now is much more clear.

Regarding your issue,no other option then waiting for new firmware, by Auto update.

I just got my R646 delivered less than 48 hours ago, and love it, but have just joined this thread. Anyone here root, hack, or overclock it yet? I've enabled developer options, and decreased animation options to 0.5x, but wanted to play around with it a bit more. Any help is appreciated
[Philips, Sony, TCL Android TV] djalosha:
I haven't had any issues with my new Google TV. I recommend going a few routes - to start. First, choose "apps only" for your home screen. Second, turn on developer options and adjust the transitions to 0.5x. Third, use the App/Device Manager to clean up the background apps. If that doesn't do it, I recommend manually force-closing some apps. Most of them seem to stay on, in the background, even if you exit out of them. My TV OS has been faster than my other Samsung TU7000 - running Tizen

What's the difference between this OTA file and the current firmware? I just updated to the 4.19
[Philips, Sony, TCL Android TV] matrix79:
No new OTA update. Still version V8 R51MT06 LF1V114.020348

What is 4.19 ? :unsure:
[Philips, Sony, TCL Android TV] PepeBlanco:
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.

Sorry, I was having some issues and couldn't finish typing - while at work. I was referring to the kernel version being 4.19.116...I had a feeling, but got excited that it might've been a ROM or something I could flash my TV with lol. Has anyone, including yourself, hacked it yet - in this group? I'm not complaining about the processor, and like it, but I feel like there may be governors on the refresh rate and CPU

Well, the Harmony remote doesn't work well with this TV. No I tried 2 different Harmony remotes and neither worked 100% like they should. Right now that/this is the only thing keeping me from giving the TCL 6 series a shot again. I really liked the picture of the tv but all the little software...

R166 is IMG file and can be flashed on any other version.

Ok thanks, so to get to V254 from V277 I have to flash VR166 first? C725 doesn't recognise V254 zip file.
[Philips, Sony, TCL Android TV] christonge:
By

Yes, you need to flash the R166 IMG file first and then apply the V254 OTA file update to that version. As explained by @stasiof further back in this thread you need to rename the OTA zip to R167 for it to update.
[Philips, Sony, TCL Android TV] stasiof:
Yup.... 👍

So managed to install V254, but now have lipsync issues when connected to AV receiver.. I've tried turning off all of the TV enhancements...
[Philips, Sony, TCL Android TV] dailos78:
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 :)
[Philips, Sony, TCL Android TV] christonge:
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.

Hi there,

I recently bought a R646 55 inch android 11 TV set. There were some graphics issues initially, which then I updated the TV to V8-T615T01-LF1V082. However there are occasional blackout and I'd need to off the main supply and restart the TV every now and then.

I saw your post and downloaded this "V8-T615T02-LF1V097.000073" and put into the thumbdrive trying to flash the TV. But the TV don't seem to capture the file even if I tried local update. Kindly advise.

Many thanks
[Philips, Sony, TCL Android TV] stasiof:
To install V097 (original firmware for R646), need T615T02 IMG file, which is not released.

However, you can still use C728/C825 firmware.

As, you are on V082 now...look for V083 in this thread.

If you want to update to Google TV, search for V407 IMG, then update to V414.
[Philips, Sony, TCL Android TV] jorbik:
Hi everyone, I own a Tcl p725 with firmware V8-R51MT02-LF1V272, I have a problem with fast forwarding of MKV files it doesn't allow me to do it. The error it reports is: unable to search for file! In addition to this, often looking at the MKV file, after a while it jumps to the next file.

How do you think I can solve the problem?

I've tried various types of MKV files it does the same thing with all of them.

Thank you
[Philips, Sony, TCL Android TV] geetv:
Thank you for your reply Stasiof !

I've did a local update to V083, and the blackout issue is still around. Previously when I first gotten the TV, it was on V062, then I updated to V082, and now V083 OTA. (-->Local update) I have never flash firmware or any IMG files before. Am I doing something wrong?

Is it better to update to Google TV instead as you mentioned (If you want to update to Google TV, search for V407 IMG, then update to V414.) Read some article that TCL had some update in late December.

Kindly advise, this TV is just 1 month old. For Reference below when I just got the TV. Oh, and why the Model Number is "iniGetStr Failed"?
[Philips, Sony, TCL Android TV] stasiof:
Yea, try Google TV......V407 IMG>>>>V414 OTA.

Anytime you can go back to Android TV with V083 IMG file.
[Philips, Sony, TCL Android TV] perrythefirst:
V272 for me is very sluggish/buggy, applications like HBO Max and Hulu crashes all the time, and as you mentioned, local video files (h265 4K HDR ~24GB/2 hours) stops abruptly so I had to seek most of the time then it stops again about 10 minutes. I flashed my TV already with Google TV (R51MT02 to R51MT05, V254) and it's way, way smoother, worth the resetting up of everything, though just make sure you get the correct firmware for your region.
[Philips, Sony, TCL Android TV] stasiof:

Which update from early version I made manually over zip file on pendrive. OTA never worked for me at first it was showing problem with connection which I had. Now it's all the time something like this "your software is up to date".

But you say they released v083 and even Google TV with number like v407 v714.
