Now open the connectivity kit and do a "check for update". It will download and place the files in the correct place. I don't think you have files placed properly in the new correct location. Just let the connkit handle it.

Put the calculator into update mode. I assume you are on windows. Let it detect the calculator and it will prompt for an update. It needs to run the 3 times to send the 3 files. Then try the C-F-O thing as I mentioned to get into the factory menu. You are trying to format the C: drive to ensure you have an empty filesystem.

I did exactly as you said.

1- delete the firmware files
2- run connkit
3- update firmware to the last version
4- update the calculator firmware using connkit and send 3 files
5- tried C-F-O and format C unit.

Nothing happened.

There are any problem if I update the firmware without the battery just using the usb cable?
