I’ve used the installer v0.3.0 on Linux to flash IodéOS 7.4-20260401 on my Moto G32 (devon).
As I’m coming from LineageOS, I came across the “OEM unlocking” issue, for which I’ve documented the workaround in this comment.
Do you recommend always starting from the stock ROM to install Iodé? Because Lineage makes that requirement explicit in its installation docs.
If I don’t quickly respond to the bootloader lock prompt, installation ends with an error, even though the system was successfully installed (with an unlocked bootloader) at that point.

A question about the Iodé (network blocking) app: does it impact system performance in any noticeable way? For instance, I’ve noticed some extreme stutters and freezes while downloading a few torrents with LibreTorrent, which didn’t ever happen on LineageOS. I’m disabling blocking while torrenting for now on.
IodéOS is also affected by this LineageOS issue, which makes recent apps constantly have to reload and lose their state while multitasking, and eventually leading to a system reboot. A few other Motorola users have confirmed it, but the maintainers haven’t replied yet. An Iodé devon user reported no such issues, though. If you’re a devon user, please leave your feedback.
My guess is that this is the work of an overly aggressive out-of-memory killer that closes any apps that haven’t been focused for a minute or more. It only starts happening after some uptime and moderate multitasking — never in the first few hours following a reboot. RAM usage reported by the system show a decent amount of free memory.
All I know is that the last version of CalyxOS (based on Android 15) is unaffected, because I’ve used it for almost a year, running the same apps I do now. So far, every Android 16 build I’ve tried has this issue.
