Yesterday I was reading Ledger Recover FAQ and there is a similar question (but about second operating system) in their FAQ, it may be interesting for you
Oh, don't get me wrong. I am under no illusion that a new device makes zero technical difference to existing devices. Even without this firmware being deployed to existing devices, it is now abundantly clear that Ledger have been lying for years about the capabilities of their secure elements. I was simply pointing out that if I was a Ledger employee/board member, then I would have done the tiniest bit of research first, realized that 99% of existing customers hate this idea, and suggested launching it on a new device only and saying nothing about our existing devices.
It's good that they weren't this smart, though, since it's served as a big wake up call for people to stop trusting these shady third parties. Unfortunately it seems many people are simply jumping from one shady third party (Ledger) to another shady third party (Trezor).
Is there something wrong with Trezor at the moment? Just asking. It's an open-source and you can verify whether the code of bought hardware matches the publicly available open-source code.
All their devices suffer from unfixable seed extraction vulnerabilities, which they deliberately sweep under the rug and do not tell their users how to mitigate against. They also have a
very pro-government, pro-censorship, pro-surveillance, and anti-fungibility ethos, as shown by their support of AOPP and their partnership with Wasabi and blockchain analysis.
