npub1d76s7zapvltswuyrayjk9kwey4jqkja0frtkfxkarszf0fykjzwq93897u (npub1d76…897u) unfortunately it’s SUPER dependent on the specific hardware and oftentimes the bootloaders are locked down. I believe it’s similar to the state of Android phones where a few with unlockable bootloaders exist, but the vast majority require an exploit if they can be reflashed at all.
This is where I feel like Right to Repair regulation should require reflashability at least after the EOL date, but also I feel like congresspeople would not understand the concept at all…
