Another interesting update ergarding Coldcard Q crap wallet,
First they lied about having open source code, but later they changed it to source viewable, but even that is not exactly true.
Coldcard is using called Boot ROM, according to them this is piece of code stored in ROM, but they are hiding the fact that this code is totally closed source, you can't even view it.
If you ask them about this issue they will avoid the answer and block you on social media, like they have been doing for all other issues.
This is another confirmation how Coldcard and NVK continues to deceive everyone including their own customers.

Boot ROM is a piece of code stored in a Read Only Memory (ROM). It is the very first code executed by the CPU when it is powered on. This code contains critical instructions to configure the system-on-chip (SoC) and allow the SoC to execute legitimate applications.
