A friend of mine gave me his kronos considered as "bricked".
Kronos 1 88.
In short : the mainboard has burned. He replaced with a new one bought from Korg (Intel D510). The SSD seems not original also, as it's a Kingston SSD 128gb.
When i got it, the keyboard was not booting, displaying a "19, keybed" error (file system corrupt...)
I did a full format + install on another SSD (the same Kingston 128gb) i had in spare in a drawer, because i wanted to keep his SSD intact, just in case.
After many aborted trials with Kronos V3 DVD, i managed to finish the full install with V2.0.2 DVD.
But when it came the authorization process, the problems started again.
I re-registered the Kronos via korg.com, with the Public ID displayed on the keybed, the serial number, etc etc.
I got a .reauth file i downloaded and put on a freshly fat32 formatted USB stick.
The synth says "authorization file found" then "success" but after reboot, i'm back to the authorization screen ever and ever.
I don't understand the problem. My .reauth file is sized 80bytes, it seems really little... i wonder if the authrozation process on korg.com is faulty and give corrupted .reauth file ?
Anyway, i need help to bring this keyboard back working. So, thanks in advance for your answers
(sorry if i made mistakes in english, i'm french native...)
