updating firmware problems *Sigh*

I just bought ultra plus 256gb ssd and through many recommendations I decided I would check for firmware updates and do so before I did anything else with it… Did the update all updated fine, pc restarted and now I can’t find the ssd??? Even the toolkit it doesn’t show up? I’m quite new to upgrading parts so I’ve followed all the instructions. Only now I have found similar post where the answer is the update killed his ssd and has to send it back??? Surly it would be cheaper if sandisk updated there toolkit to avoid this? I’m not sure if this is the case for me but I’m guessing so… But if anyone has any suggestions feel free to hit me up and I’ll give it a go to my best abilities. Ps the youtube video for updating fw looks so easy lol :frowning:
