any links that let you download firmware JL10, right now i have JL11 but i can’t reverse it.
No, it’s not available, and we haven’t seen it anywhere.
Sorry, it isn’t possible to get hold of JL10. JL10 is LG’s first version of firmware for the GSA-H10N. That is the version that came pre-loaded with 1st generation H10N drives. LG never makes the first generation of its firmware available for download.
There is also no way to extract the firmware from an existing drive.
