Hi everyone!
I came here to say thanks to radioman! He saved my original TL866CS (converted to A) from its own creator.
I had problem when I downloaded, currently the latest V6.85 sw. It offered to update the firmware on my TL866A , I accepted and regretted. From then my TL866A could not read the Chip ID, and it was unsuccessful to properly program or erase the serial flash memory (SPI).
After a google search I found this forum and radioman, and solved my problem by forcing the bootloader and flashing to lower version of firmware.
Thank you sir, again!
