Hi, i'm stuck on this V999 version on my C825, what can i do ?
Thanks.
Flash V062 IMG file (post #47) first ,then after can update to V072.

Backup your additional apps somewhere, as will be deleted.

Pressing Off TV by remote 2-3 sec and Off.
Copy "update.img" on USB and insert in TV.
Press and hold power button on TV ,until front LED start to blink.
Release power button and wait for update finish.
Once you are back to V062, can use local update in setting for V072 zip file.

I have V231 and p725 now, but today I found out that there are V238 and V267. Why don't these firmware versions come to me via OTA? If I update myself, do I need to do a factory reset? Will I be able to roll back if I don't like this firmware?

Read above....user just update from V231......
Auto update depend on country location, will take a time to be available.
No need factory reset, only maybe reset in service menu.....
If you read more, I think rollback with OTA is disabled.
Only can go back to V256 IMG file, which will wipe all your apps.

You can google about this, even Sony X90H has this problem.
Latest firmware is V072, but I doubt can do anything.

Some links....

R011 is custom firmware from April 2021.
For update, try to ask your seller.

Btw,
if you want to risk , R51MT02... V267 can be flashed ,by renaming OTA zip file V to R.
Also, you can found in previous posts......R51MT02....V256 IMG file.

    Hi,

    Sorry if this is asked before. I just bought an export set (Japan) of TCL c825. It seems that Dolby Vision has issues, that have the sound but no picture (all black screen) while using Nvidia shield. Using the TV itself the Netflix has like buffering has issues unable to get a clear image. Disney+ unable to load the movie at all.

    Any chance could it be the firmware issues? Hope to get some sharing on this.
    As I know C825 Japan version is downgrade from Europe version.
    Old Realtek SoC RT51M and only 2GB of RAM.
    Not worth at all, waste of money.
    Edit:
    Japan C825 same spec as P725 or C725.
    If any chance RETURN back Japan C825 TV !

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

    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!
    Hi, first of all , yes you need to update firmware.
    Instead of here, you can found TCL links also on telegram...
    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.

    Hello everybody. I recently bought the TCl 50C725 and I am satisfied (especially after the adjustments I found in this forum; I followed the previous model C715).
    For the Italian market there is no PVR and Timeshit; as you indicated, I would like to try to change the Project ID of the TV (currently 6446).
    Compared to what I found here on the forum, now the Project ID is with 4 digits instead of 3.
    Also in the list of TCL Project ID sheets (let me thank stasiof for the great work he does to the community) clearly I don't find my TV (too new) and I only find 3-digit Project ID.
    Do any of you have experience with the Project IDs of the new 2021 series (C725)?
    In the meantime, thank you all for the great job you guys do!
    For 2021 models Project ID is not released yet, so need the time to be released and change Project ID.

    Changelog is very rare for TCL firmware.

    Are there special instructions for updating the firmware from USB?
    I have C825 and tried both placing a zipped and unzipped firmware on a FAT32 USB stick. Then going to Android TV settings - Device preferences - About - System update - Local update. But the update isn't detected.
    What firmware you running now?
    Do not unzip....copy/paste zip file as is. Try to change USB drive.
