well you cant upload a new bootloader without a ISP (hardware) so scratch that one.
No idea how cura does uploads though... I would expect that it emulates avrdude upload over serial, in which case there is an upload baud rate and protocol somewhere...
I was curious, so I took at look at cura... it uses protocol stk500v2 upload baudrate... I couldn't find before I got bored.
