Problems and improvements to the FW display are better addressed here: https://github.com/bigtreetech/BIGTREETECH-TouchScreenFirmware/issues The FW repository is tracked by multiple users and programmers.

It depends on what HW you have. If you don't know, take a picture of the display from both sides and send the photos. Then I'll tell you which file...

Bad photos. can you take a better picture of this so the text can be read? Or write the display type and processor model  

You use: BIQU_TFT35_APP1_V2.0.27.x.bin

What system are you using? TFT is optimized for Marlin. Other printer FWs are supported only partially or not at all.

TFT updated fine. What FW is your printer using? Marlin, RepRap, Repetier, Smoothie, Klipper, Prusa... ?

> I meant config file included in the software, there are two, one for reprap and the standard one,that I used. config.ini Both are the same, they differ only in...

Connect the printer, if you have the correct serial port activating and the same speed of the serial port, the TFT should work.

Set the same serial port speed on the TFT35 as you have on the TFT24 and it will work as well

You have many TFT displays and SKR boards. I got lost in translation. :-) So what is the result? Is everything working for you?
