How to update firmware for SSD

Do you know if it affects the disc content?

You should assume it will erase the SSD contents. Then if it does not, Merry Christmas!

The reverse assumption is truly horrible. Don't go there.

No I just made sure I had a current time machine backup. The drive content isn't touched but as Grant mentioned, plan for the worst!

David, I'm in the same case. Have you succeeded in making the boot CD working ?

Would appreciate if you could share your experience.

Thx.

can you please conferm that it worked back to normal?

I am not sure I understand your question.

I did not have any luck updating firmware via the Samsung method and ended up using Bootcamp.

No, I never did and so have not updated the firmware.

Thank you for sharing your experience !

I will retry as soon as possible by dowloading the new iso and burning it again to a CD.

Thanks again.

In the case of the 840Pro, the same firmware file can be used for the various 128/256/512GB sized drives.

May I suggest that you do not post your machine serial number on a public forum. 😉

On non-Apple supplied SSDs, TRIM is not supported. It can be enabled via a hack, but it is tricky, if version upgrades provide newer versions of kext files.

If you format the USB to a FAT and then run dd if=YourISOName of=/Volumes/USB, can you boot from the USB?

thanks for your answer: but can you be more specific on the different steps?

thx

Thanks, renevoorburg The Samsung uses FreeDOS, but this is worth a test.

The 05B0Q version does not work via USB, but 06B0Q does work.

Modifying a kext by doing hex byte replacement is rather a hack. Apple does not want you replace hardware in your Mac, but you should but it from Apple. 😉
