Hi i am using cooltec downloader and trying to upload it to my cooltec. uploader cant recognize file 143 which is a rar file.

rar is a zip file... get the rar utility and extract it to a folder, then your loader will see it. Good Luck !

i am using cooltec stb loadar. its firmware file or something. Is there another one if so where can i find it. thanks for your reply

I know what your using..... go get the rar utility and extract it. rar is just like a .zip file.. you have to unzip a zip file to make it work.
143c2.bin.rar needs to be unzipped.
goto win-rar.com
