Got stuck with the connkit, that doesn't find an update with the prime. Then used the us tool.exe app, changing the files in the setting page to the three that appear in the firmware. The calculator won't restart, (black screen and no way of making it work), but it will go into recovery mode with clip and Symb. It won't "downgrade" to any past firmware (it says that it can't write anything with a recovery mode less than v16). What is the procedure to successfully upgrade it from here?

I can't get it into diagnostic mode, either.

[edit] sorted out. I edited the contents of the usbtool.ini file, and changed the number of files to move from 4 to 3, and also the addresses (the rom file on block zero, the master on block 10000, and the app on block 50000). It worked like that!
