Downloaded the proper firmware (thanks for the guidance - the box ID versus the ID in System Profile - they were different). Burned it to a CD, booted from it. Must say here that my former internal DVD/CD is now external since I put a HD in its place. The boot goes to black screen, some text scrolls across the top then it goes to a blinking prompt and sits there. The CD spins down and nothing heppens. If there is a time frame between that first line and further action I’ll try again, but I felt that was as far as it was going. Don’t want to go mucking around and render the SSD to becoming a paperweight so I’ve stopped for now until I hear back on this. I don’t think the fact that the SuperDrive is now external is at the root of it since it does boot from it. I do, however, not use the “C” key to boot, I use the Option key to select the disk. The disk being external now may not be able to do that (didn’t try).
I have the SSD Ultra+ - the box lists it as a DHP, the System Report shows: SanDisk SDSSDH2256G. So I downloaded the H2 version. I don’t know how critical this firmware update is, if it isn’t I am going to cease trying since it could end up in disaster if done wrong.
Thanks for any guidance.
