Hi again,
Thanks for the help and the messages so far
I've successfully configured a new sdcard with hekate / atmosphere and made some backups.
I also created a partition based emuMMC to keep my sysnand as clean as possible ^^.
Now I want to go one step further and update the firmware to the latest version.
Currently 9.1.x on both sysnand and emunand if i remember well.
I don't want to mess with the fuses (burnt fuses displayed : 12). If my memory is correct, updating the CFW version in the emuMMC will not burn fuses right ?
Also the recommended way to update from atmosphere is by using daybreak right ?
