Dear 808, from my own perspective your question is perfectly understandable.
I would help if I could and would do it for free in order to practice, for I have a 10 v3 to do, but I am not in the USA.
I found myself to dislike the flashing a Jolla thing.
Although I have been thinkering with “devices” from the 90’s when getting access to procedures descriptions & step by step guides by internet became easy and I do remember tomshardwareguide as sysdoc.pair.com …
Simply because it is part of a standard commercial procedure yet still it is nerdy and not at all fun, nor is it giving me the satisfaction of for example overclocking a 3Dfx video card by command line.
Every time I need to do it I have to waste time to look up the procedure again. It takes way too much time.
If I had a shop representing Jolla I would not have this issue. I would remember the procedure, be confident and put a fixed price on it.
Why not walk into a “phone repair shop” , show them the procedure, ask if they can do it under warranty or their insurance?
Further Comment:
People here tend to overlook the need for software installers in the smart phone branch.
It is is 2 minutes before twelve to ever get rid of Google spyware riddled phones, websites, TV’s, smartwhatever if we don’t want to become a patent in Google’s portfolion and to do that offering expert smartphone setup services way beyond the flashing of firmware is a critical factor.
