Hi,
I’ve found something I suspect to be a mistake in iso (at least for the SanDisk Ultra+ SSD SDSSDHP-128GB model, I have not checked the others).
there is an argument passed to the kernel (found in menu.lst file) which contains a parameter blocking the firmware upgrade, I think it is related to a serial number, the value is near of my SSD S/N.
I’ve tested the ISO on three differents computers (two laptops and one desktop) without success.
I finally managed to do the update by removing the parameter from the colored boot / grub menu (‘e’ key twice, modify / delete the entry, ‘return’ key and ‘b’ key to boot)
!!! Note that at this moment the sandisk SSD I want to upgrade was the only SSD/harddrive/whatever-disk connected to my computer, don’t know if it’s important but I prefer to not take any risk !!!
the line to edit is :
kernel /EFI/Boot/vmlinuz quiet splash locale=en.UTF-8 loglevel=2 sandisk.drive=131996401388 sandisk.command=ffu
and the parameter is
sandisk.drive=131996401388
I’ve removed the parameter, booted and I’ve been able to update my SSD easily.
If ever it may help…
