Trouble updating Prime firmware

[cyrille de brébisson]

Hello,

The "new update method" would NOT be the reason for the success.
You have never heard of it... because it's new :-).
This new method avoid the use of the 'special update' software which requires administrative privileges by using application level USB messages to send the large update files, and then reboots in bootloader mode to update the calculator locally.
However, this method will only work with a calculator that has the new firmware and which is running correctly. Any future FW update will be able to use it (this is NOT a future looking statement BTW and does not mean that such FW will be released, just that if it was released, it could use that method).

Anyhow, I am glad that you were able to complete your update and that it is now working.

I will investigate this error 14.
