If not, power it off/reset and hold down the ALPHA C - F - O keys. (all 3 at once) while the unit appears to be booting. Does a menu come up? Go into the FLS menu and do a format. 9 to reset (or reboot) once that is done. Any change?

You mention you are running the "Updater.exe" directly? I would recommend not doing that. Any calculator found in "updater" mode with the "recovery" showing should be detected and it will kick it off automatically. Running it directly can possibly mean the wrong update files get detected and it trys to use them. Please check on your system that there is no more then 1 place where the "PRIME_OS.DAT" and other files appear to ensure that it is not potentially flashing a version you are not intending to do.

I tried to update again holding down the baskspace key but nothing happened. I format the unit C using the diagnostic mode , didn't solve.

I can't downgrade using the connectivity kit. I use the following procedure:

1- put the calculator in recovery mode (v16)
2- open the connectivity kit
3- click to update
4- I received the message " There is not available updates"
5- the calculator automatic leave the recovery mode (v16)

Besides that I went to the temporary files and leaved just 1 file PRIME_OS.DAT, but didn't solve too.
