Is the OS from the Time Machine backup running on High Sierra?
The bootrom may be out of date and causing an issue?
Sorry I didn't say it very clearly.
I installed the Time Machine backup to my Kingston A1000, which failed every attempt to boot with a crossed circle. Then I overwrote the same A1000 with a fresh High Sierra installer. After this it booted to my Time Machine backup.
It continues to work correctly after that. It's one of those things I don't
need to understand because ...it worked... but still weirds me out.
Yes I believe the Time Machine backup had already been updated to High Sierra. That's what it is now too... although the Disk Utility you get from holding Option at startup appeared to be an older version when I booted from the Time Machine backup than the fresh installer.

A quick overview!
I just got a PM asking me to update my post with links since this thread is 100+ pages and a little hard to get into. In an effort to contribute and help others here's a quick summary:
The basics
If you've updated to High Sierra on your internal drive, your boot rom should be already updated to work with a third party SSD.
Remove the bottom cover of your laptop, disconnect power to battery, remove drive, install new drive with adapter, reconnect battery, boot Mac to installer or backup, install system on new drive. You're good to go.
If your old SSD is dead and you didn't update to High Sierra, you need to find a stock apple AHC SSD and do that. Don't waste your time, it's the only way.

The adapter -
Rev B Sintech adapter with tools. I used this one - don't remember where but somewhere in this thread I have a vague memory of someone saying not to use the Rev A., and that the long black (C?) only works with MBP

different drive types, pros/cons, and describing the basic issues with upgrading drives / Also shows how to use

My success was with
- mid 2013 MBA
- boot rom MBA61.0107.B00
- Kingston A1000 512gb
- Sintech Rev B adapter
I chose the Kingston A1000 because it looks like it will give me more or less stock battery consumption and speed for my MBA. It's also one of the cheapest options and is double the size of my SSD that died.
If I have anything inaccurate here please correct me.
