Where to download recovery firmware for Thomson 55UG6300 MS6586?

Mark: THOMSON
Model: 55UG6300
Chassis: MS6586
More information: Good morning, I come to ask for help to recover the firmware, if anyone could send the RECOVERY firmware file I would really appreciate it.​
I already tried the procedure of unplugging the TV and holding the power button while plugging it back in and it "says software file check failed", so I need to recover the firmware via USB.
CURRENT SOFTWARE:V8-S586T07-LF1V020
THANK YOU
Could you please share the country/region of the TV and a photo or full text from the back label, including product code, serial number, panel code, or any “V8-...” / “TCL” identifiers?

What exact recovery file did you try via USB, what was the filename, and how was the USB prepared/formatted when the TV showed “software file check failed”?
I haven't tried USB yet, as I don't have the correct firmware file, I just tried the method I described.

On the SM SEARCH portal, simply type in ‘THOMSON’ and the service codes and EEPROM will be displayed

@ChrisTV8 In G......just search for ‘THOMSON 55UG6300 TV service mode’
is the standby LED lit? If not, check the power supply or search for ‘THOMSON 55UG6300 TV’ on eBay
eBay will display parts for the THOMSON TV
