Dont install it, buggy firmware!

cant even playback video smoothly, lots of stuttering on playback

worst than v028, stick with that instead.

v062 does not really fix anything, local dimming is still broken (grey bars on movies) and now stuttering on video playback

Interesting, as majority of users has no problem with this version.

Even no grey bars at all.....on various forums....

Greetings. There is a question about the update. Someone would write why you can't see the TV update? The subject TCL 43C645 Googletv. Current Software Version: V8-R51MT05-LFV576 I downloaded the last version: V8-R51MT05-LFV578. I copied it to the TV, downloads, directory. I didn't pack out, left *.zip stock. The TV can't see it. Of course I chose the local update. I copied to the wrong place? An SSD is connected to USB. He doesn't see it either. Obviously I watch the movies and read the player. Thank you for your help in advance!
[Philips, Sony, TCL Android TV] BabaOeeMario:
Thank you so much for this! I'll try it today!

I have one question though now. Is this the original firmware for the Q750?
[Philips, Sony, TCL Android TV] stasiof:
Q750G, QM850G and R754 share same firmware.....T615T02.....
[Philips, Sony, TCL Android TV] svgyula:
Dear gentlemen! The problem has been resolved! FAT32 Pendrive see and do the update after copying! It's weird that the system can't do this from an SSD or HDD drive ....
[Philips, Sony, TCL Android TV] BabaOeeMario:
But if I downgrade to V8-T615T02-LF1V273, is that the version I had before I updated to V8-T615T02-LF1V283? Because I didn't update the Q750 when I set it up. I was using the firmware that came with it. Was that firmware V8-T615T02-LF1V273, or do I need a different firmware for its original out-of-the-box state?
[Philips, Sony, TCL Android TV] reg66:
Dude, maybe @stasiof happens to know, by chance... But, I'm not sure he'll know which rom/firmware version your TV shipped with. That's really up to you to note such things in the beginning.

Good luck with the long shot though!
[Philips, Sony, TCL Android TV] BabaOeeMario:
So I haven't been able to install the firmware, with work and all. But before I begin I have another question: do I have to install both the IMG file and the OTA file, or just one?
[Philips, Sony, TCL Android TV] stasiof:
To downgrade version, you need IMG file.

For update can use OTA zip file.
[Philips, Sony, TCL Android TV] BabaOeeMario:
Okay, but like I asked before: is V273 the original firmware of the Q750?
[Philips, Sony, TCL Android TV] stasiof:
Yes, all is original.

There is no "Home" made TCL firmware.

First Q750 models came with V273 version.

Hello again! I successfully installed V273 on my TCL Q7 with the help from stasiof and I'm satisfied with the results. But now I have another question: what is this firmware for, and can I use it on the Q750: V8-T615T02-LF1V011.

Thank you in advance!
[Philips, Sony, TCL Android TV] stasiof:
V011 is for early released R646 and not for Q750.

Okay, thanks for all your help! Just wanted to know.

Dear gentlemen! I put up the latest update. Unfortunately, it did not help the control tools! If 2pcs Bluetooth tools are on the applications will freeze within 5-15 minutes! You can never connect the control arrow! If Tool 2 is on, there are 2 arrows on the display! This problem was already solved by the 8 -year -old TV and this Android was not! In 2023, Bavó would think that this should not be a problem! But problem! And the factory remote control does not work properly for all applications! These have to use the keyboard+tapi pad! Without it, it doesn't work and the sroll shows nothing! You can just guess where the cursor goes! That's a big zero! No application if I quit it! BUT! A "running applications" operator no longer fit into what could see the system's resources in the background! This system is far weaker than any Windows! And the need for resources is huge compared to your knowledge! So it's a crap!

Does anyone know if the problem of raised blacks/local dimming zones not turned off will be solved ? I'm on the latest software version V562 and it leaves much to be desired. On full screen 16:9 content it works fine, but for any cinemascope or 4:3 content the black bars are noticeably on, when the TV is capable of very deep blacks if you were to turn them off.

This makes it very unusable for movie appreciation, to the level of deserving a return.

Hello, recently I bought 55c645. Overall I am delighted with this TV image quality and paid only 370 EU.

But I have two problems.

1. Having Dolby vision issues on Netflix. The transition from dark to light images is some kind of flickering ( If I could turn of Dolby vision in Netflix I would turn it off, but Netflix doesn't have that option).

2. When watching TV series or Movies from USB flash. There is some kind of buffering lag (don't know how to exactly express it), that lasts for a split of second and repeats itself every few minutes.

Can someone recommend how to fix those issues? If it is a software problem, TV box would fix it?

When I go into Picture > Advanced Settings there is no "Expert Calibration" no matter what picture mode I am in, any idea why this is?

Can it be solved with a firmware upgrade or is this controlled some other way?
