So I was trying to update my dash a few years a ago with no luck and decided to try again, again with no luck. It is a corona 4g on dash 17489 and whenever I try to flash it with simple360nand flasher, it all goes flawlessly, but when I check to see if it updated to the new dash, it is still on 17489. Could anyone help? (have have tried j-runner and flashed it multiple times no change).
