Can anyone help me figure out if this hard drive on eBay would be recognized by my mid 2015 15-inch Retina MacBook Pro as the "original" hard drive so that I can upgrade the firmware and upgrade to Mac OS Monterey?

Below is a sequence of messages from this previous thread about this issue and why I suspect that this hard drive would work for this purpose. Huge bonus points if you can help me fix the error in Terminal so that I can upgrade the firmware manually without buying a hard drive at all!

Thanks in advance.

Thank you. Could you double check for me, is this used one on eBay the right part? I think it is because I see the number 655-1837C in the description like in the listing you posted.

I believe this is your issue -

You might have to buy one -

Does anyone know what the original OEM SSD hard drive for a mid 2015 15-inch Retina MacBook Pro (model identifier MacBookPro11,4) is, and how I can buy a used one, and/or how to fix the error in Terminal I'm getting while trying to manually upgrade the firmware?

I'm trying to upgrade from Mac OS Catalina to Monetery because GoodNotes on my Macbook stopped synching with it on my iPad because the version on my Macbook is too old, and I can't update it because Catalina is too old. I can't currently can't upgrade to Monterey because the person who we bought the computer from swapped out the original OEM SSD hard drive for a third-party SSD drive, so the OS won't update the system firmware and install Monetery. We do not have the original hard drive. I tried this workaround here to update the firmware despite the third-party drive, but haven't been able to get it to work. I am attaching the readout from Terminal I am getting currently when I try to update it in case anyone here can decipher why the firmware is still not updating.

If I can't get the firmware to upgrade manually, then my next step is to try to buy a used "original" OEM hard drive for the laptop and reinstall that temporarily so that I can update the firmware. Does anyone know what the original OEM SSD hard drive for a mid 2015 15-inch Retina MacBook Pro is, and how I could find one that the system will recognize as the original, without paying an arm and a leg?

Yes, it looks like the right drive since it looks like it came from a working MacBook.

Apple used SanDisk to make some of their 128 GB drives before switching to better-performing drives from Samsung.
