I have downloaded a bootable SD image from UV4L with which to run their webRTC demo and the SD image exhibits this thunderbolt [will not boot] problem in my 3B+. Naturally I have asked them to provide an updated image but just in case I don't hear back from them anytime soon, is there a way I might update their image using just my 3B+ ?

Perhaps they wish to reduce the strain on their servers or not flood people's inboxes.
Whatever the reason, I never saw your 2nd post until now.
That's unfortunate, considering I spent a good amount of time writing my response to your 1st post!
Nonetheless, since I took the time to write it, I'm sending the whole thing anyway:
Your question reminds me of theory versus reality.
In theory, there are all kinds of wonderful "projects" you can do on a computer.
In reality, you better be prepared to spend hours, days, weeks or even years to make it happen!
In many cases, it gets even worse: Time and effort may prove to be insufficient and your goals will never be achieved.
Unless some pioneer has already blazed the trail by publishing a clearly written, step-by-step tutorial that doesn't "assume knowledge" and skip over essential details, the vast majority of people will be dead in the water. This is especially true when it involves complex things like video.
But it gets even worse than that: Unless these tutorials are continuously updated to reflect the never-ending changes in the "software environment", the instructions will often expire and fail to work.
In my experience, most "tutorials" on the Internet are not even worthy of the name.
As if that weren't enough, for a whole bunch of cultural and psychological reasons, the few "gurus" who truly understand "how to do it" tend to be quite useless. That's because they typically suffer from the "curse of knowledge
" and lack the temperament or cognitive ability to explain things to a wider audience.
Why? Because everything is "so obvious" to them!
Or, if they do know how to explain things with sufficient detail and clarity, they typically don't bother sharing their privileged insights. After all, they already know how to do it – so it's not a problem for them!
In fact, if you look at the most advanced and prolific posters on this website, most of them have NEVER
posted a single tutorial. Never – not once.
I may not be a guru, but I have taken the time to write a series of comprehensive tutorials that take everything I just said into account. I try to write high-impact tutorials that address extremely common things that many people would appreciate – like my tutorials on playing videos
or viewing images
So, back to your question:
I can tell you already know this, but your query is definitely off-topic. You're asking about an "alien" operating system that has nothing to do with my tutorial or NOOBS. [Other than the fact the alien system you're asking about is somehow "based" on an old version of Raspbian – and the title of my tutorial coincidentally includes the phrase "won't boot"]
Nonetheless, I understand your frustration and I realize you were just fishing for an answer.
So here's my suggestion – a suggestion that may or may not work. I say this because I'm not about to take a deep dive on your project or learn about some random operating system you found on the Internet. But based on my quick take, it's what I would try if I were in your shoes:
One way or another, get your hands on a Raspberry model that's older than the 3B+. A model 3B or even a Raspberry 2 will do just fine. Maybe a friend can let you borrow one. You only need to get your hands on it for about 5 minutes.
Then, use the older Raspberry to boot the old operating system you found.
Once it's up and running, simply connect to the Internet and run the following command:
With a bit of luck, that will update your "boot code". At that point, just pop the SD card into the 3B+ and it just might boot!
I wager that my suggestion has a 35% chance of working. If it does, it does – if it doesn't, it doesn't!
Note to all the other Raspberry users out there: Unless an expert has specifically told you to do so for a specific reason, you should not run this command.
PS: I just read your other post in the Graphics forum. This is not the place for discussing it, but try the outstanding motionEyeOS
. It just might meet your "video monitoring" needs. Over WiFi, the latency is just a few seconds.
