ITI 5800s Nbox Conversion to Enigme: Issues with Tuner, Uploads, and USB-UART RS232 TTL Converter

Hello, I'm trying to convert the tuner to upload Enigme and OpenPLi or anything else. Nbox bought on ol ... BSKA version, without the card only pops up Card error nothing can be done: / I use this manual generally available on the web Software change tutorial in NBox v8 Final BSKABSLA
I have a usb-uart rs232 ttl converter from allegro with a pl2303hx chip works on win xp.
I tried to run blackbox but I never got the terminal "testbox" if I could type something.
Uploading the first software takes 10 hours, after uploading I connect the jumper to 20, and then I can not do anything else because the hyperterminal does not work, the blackbox also does not, and neither does putty. I can't read the decoder to send uboot to it via hyperterminal: /
Please help me, I will be happy to cooperate and I would like to thank everyone for advice

What was the version of the original software?

I don't know because I couldn't and still can't use the remote control to enter the settings and info about the software: /

After all, he writes in the turtorial you refer to:

For BSKA Soft max 4.7ca 17 (4.7aa 17), for BSLA 4.82a 17 (4.99a 17) - update 09.2009
you have a newer soft, you will not enter the service menu and you will not do anything with this method.
